description: We study the imprints on the formation of cosmic structures of a particular class of dark energy parameterizations dubbed PADE parameterization. Here we investigate how dark energy can affect the growth of large scale structures of the universe in framework of spherical collapse model. The dynamics of the spherical collapse of a dark matter halo depends on the properties of the dark energy model. We show that the properties of spherical collapse scenario are directly affected by the evolution of dark energy. We obtain the main parameters of spherical collapse for two different DE parameterizations in two different approaches: first the homogeneous DE approach, in which dark energy does not exhibit fluctuations on cluster scales and the other, clustered DE scenario in which, dark energy components inside the overdense region collapses similar to dark matter. Using the Sheth-Tormen mass function, we investigate the abundance of virialized halos in the framework of PADE parameterizations. Specifically, the present analysis shows that the number count of dark matter halos depends on the evolution of DE parameterizations and clustering properties of dark energy. Also we show that perturbations in phantom DE components enhance the growth of matter perturbations. This result were obtained in the literature for dark energy parameterizations that are phantom at all redshifts. But we obtained same results for dark energy parameterizations which are in phantom regime and enter in quintessence region at relatively low redshifts. We also show that in parameterizations under study, low mass halos were formed before massive halos.

description: The bacterium Xylella fastidiosa is a destructive pathogen which attacks a wide range of hosts of more than 350 plant, causing various diseases. Recent outbreak of X. fastidiosa in olives and other major crops in many countries in the European Union and other countries in the region is considered a serious threat to the Jordanian agricultural sector. Therefore, a survey was conducted during the years 2016-till now for the presence of this bacterium in Jordan on different hosts including olive (no. of samples: 975), grapevine (560), stone fruits (670), pome fruits (80), citrus fruits (790) oleander (120), rosemary (225) ornamentals plants (985) grown all over Jordan. Samples were taken from plants showing suspicious symptoms and from asymptomatic plants, and potential Hemiptera insect vector samples were also collected. All plant samples were tested for the presence of X. fastidiosa using commercial ELISA kits, followed by molecular confirmation by conventional PCR using 3 set of primers. Insect's samples were tested using real a time LAMP PCR commercial kit. All tested samples did not show any positive results in comparison to the positive controls. These results demonstrate that X. fastidiosa is not detected yet in Jordan. However, extensive monitoring program and checking the borders are needed to prevent the entry of this pest into the country.

description: Family Comesomatidae Filipjev, 1918   Remarks. The monophyly of the Comesomatidae has been established only by the presence of a spiral amphid of at least 2.5 turns by Lorenzen (1994). However, the Comesomatidae are generally large species,> 1 mm long, with cylindrical body and conico-cylindrical tail. The cuticle usually has transverse rows of punctations of variable size, with or without lateral differentiation and an enlarged/elevated lateral field may be present. Somatic setae run along the length of the body in 4 longitudinal rows. The cephalic region has 6 lips and a 6+6+4 sensilla arrangement. The labial sensilla are papillate, the cephalic sensilla setose and in either one or two rings, the posterior cephalic setae usually longest. Amphids are usually multispiralled and located closely behind the cephalic setae, with the exception of Cervonema in which the cervical region is elongate. The buccal cavity is perhaps the most variable character across Comesomatidae, ranging from small and undifferentiated in Cervonema to having a sclerotized, dilated and conical posterior section with well developed teeth at its anterior margin in Paramesonchium Wieser 1954. The oesophageal lumen is tri-radiate with distinct marginal tubes. Ovaries and testes are paired, opposed and outstretched. The male copulatory apparatus typically comprises arcuate spicules, proximally cephalate and distally acute, and a gubernaculum with or without (usually paired) dorsocaudally directed apophyses.

Distance measurements as a probe of cosmic acceleration

subject: FOS: Physical sciences

description: A major recent evelopment in observational cosmology has been an accurate measurement of the luminosity distance-redshift relation out to redshifts z=0.8 from Type Ia supernova standard candles. The results have been argued as evidence for cosmic acceleration. It is well known that this assertion depends on the assumption that we know the equation of state for all mass-energy other than normal pressureless matter; popular models are based on either the cosmological constant or on the more general quintessence formulation. But this assertion also depends on a number of other assumptions, implicit in the derivation of the standard cosmological field equations: large-scale isotropy and homogeneity, the flatness of the Universe, and the validity of general relativity on cosmological scales (where it has not been tested). A detailed examination of the effects of these assumptions on the interplay between the luminosity distance-redshift relation and the acceleration of the Universe is not possible unless one can define the precise nature of the failure of any particular assumption. However a simple quantitative investigation is possible and reveals a number of considerations about the relative importance of the different assumptions. In this paper we present such an investigation. We find that the relationship between the distant-redshift relation and the sign of the deceleration parameter is fairly robust and is unaffected if only one of the assumptions that we investigate is invalid so long as the deceleration parameter is not close to zero (it would not be close to zero in the currently-favored Omega_Lambda = 1 - Omega_matter = 0.7 or 0.8 Universe, for example). Failures of two or more assumptions in concordance may have stronger effects.

description: We investigate the longitudinal and transverse piezoresistance effect in suspended graphene in the ballistic regime. Utilizing parametrized tight binding Hamiltonian from ab initio calculations along with Landauer quantum transport formalism, we devise a methodology to evaluate the piezoresistance effect in 2D materials especially in graphene. We evaluate the longitudinal and transverse gauge factor of graphene along armchair and zigzag directions in the linear elastic limit ($0\%$-$10\%$). The longitudinal and transverse gauge factors are identical along armchair and zigzag directions. Our model predicts a significant variation ($\approx 1000\% $ change) in transverse gauge factor compared to longitudinal gauge factor along with sign inversion. The calculated value of longitudinal gauge factor is $\approx 0.3$ whereas the transverse gauge factor is $\approx -3.3$. We rationalize our prediction using deformation of Dirac cone and change in separation between transverse modes due to longitudinal and transverse strain, leading to an inverse change in gauge factor. The results obtained herein may serve as a template for high strain piezoresistance effect of graphene in nano electromechanical systems.

These phases include static precipitate: honeycombs and Wigner crystals; and novel dynamic condensate: toroidal vortices and pulsating rings. The observed structures are explained by the interplay between charged granular gas and electrohydrodynamic convective flows in the liquid.

Period Ratio Sculpting Near Second-Order Mean-Motion Resonances

Publisher: name: Zenodo
Year: 2021

description: Second-order mean-motion resonances lead to an interesting phenomenon in the sculpting of the period ratio distribution due to their shape and width in period-ratio/eccentricity space. As the osculating periods librate in resonance, the time-averaged period ratio approaches the exact resonance location. The width of second order resonances increases with increasing eccentricity, and thus more eccentric systems have a stronger peak at the resonance location when averaged over sufficient time. The libration period is short enough that this time-averaging behavior is expected to appear on the timescale of the Kepler mission. In this talk, I will present results obtained from N-body integrations of simulated planet pairs near the 5:3 and 3:1 mean-motion resonances. I will demonstrate how these results constrain the eccentricity distributions of real Kepler planets near second-order resonance, placing an upper limit on the Rayleigh scale parameter, σ, at σ = 0.245 (3:1) and σ = 0.095 (5:3) at 95% confidence.
Machine learning-based approach for thermospheric density prediction

Publisher: name: No Publisher Supplied
Year: 2025

description: For satellites at low altitudes, atmospheric drag is the dominant non-conservative perturbation force and is the most difficult cause for predicting the orbits of low Earth orbit (LEO) satellites. Among all the factors affecting the drag force, thermospheric density is presently the predominantly uncertain term. This dissertation presents a significant advancement in thermospheric density prediction through the development of a data-driven framework based on machine learning methods. The proposed framework integrates data from the empirical models including the Jacchia-Bowman (JB-2008) and Naval Research Laboratory Mass Spectrometer and Incoherent Scatter Radar Extended (NRLMSISE-00), geomagnetic and solar indices, the corresponding time indices and the geographic positions, and accelerometer-derived density data along satellites to predict thermospheric density.Key contributions of this dissertation include an in-depth exploration of the critical inputs Dst and SymH indices in the framework, which help to improve the accuracy of the model in predicting thermospheric density. The framework is initially validated using the Gaussian processes (GPs) and neural network model with dropout to predict the thermospheric density along the Challenging Minisatellite Payload (CHAMP) satellite during both quiet and storm periods. The predicted results based on the proposed framework show high accuracy and quality uncertainty estimations. Afterward, we introduced and applied the deep evidential methods to predict density along CHAMP based on the proposed framework. Based on the deep evidential model, we analyze the performance of the estimated uncertainty on both storm and quiet periods.A global thermospheric density prediction framework based on the deep evidential method is then developed and validated on various satellites. The results show higher predicted accuracy than the empirical models with reliable uncertainty estimations, even for testing on future periods or on new satellites that are not included in the training data. The model's ability to predict global thermospheric density across a wide range of geophysical settings is also demonstrated and compared with the empirical models JB-2008 and NRLMSISE-00.To demonstrate the practical application of our model, we applied it to orbit propagation and compared the results with those densities derived from JB-2008 and NRLMSISE-00. The simulation lasts for 10 hours based on a storm period in 2003 and a quiet period in 2007. The results show that the orbit propagation based on the proposed model is significantly closer to the actual observed orbits than the empirical models, highlighting its superior accuracy and robustness.

description: The present paper reports an economic evaluation of the long-term benefits to Australia of research by the Cooperative Research Centre for Weed Management Systems (CRC) into the improved management of vulpia , the major annual grass weed of temperate pastures in New South Wales and Victoria. Vulpia reduces livestock production by competition with more desirable pasture species, by the production of low quality feed at critical times of the grazing cycle, and by injury to animals. A 20-year stochastic benefit-cost analysis indicated that reducing the impacts of vulpia in these pastures produced a mean net present value of # A58.3 million and a mean benefit-cost ratio of 33:1. Temperate pasture zone wool producers would capture the largest shares of these benefits, Australian consumers would gain, but wool producers in the rest of Australia would suffer welfare losses from vulpia reductions in the temperate pasture zones.

Spicules enlarged proximally, gubernacular apophyses (is) paired or single. Also, Laimella, Cervonema and Setosabatieria exhibit a striate cuticle, rarely minutely punctations have been observed in Laimella (Ward 1974; Jensen 1979).

description: A modern assessment of the classical Boltzmann-Schuetz argument for large-scale entropy fluctuations as the origin of our observable cosmological domain is given. The emphasis is put on the central implication of this picture which flatly contradicts the weak anthropic principle as an epistemological statement about the universe. Therefore, to associate this picture with the anthropic principle as it is usually done is unwarranted. In particular, Feynman's criticism of the anthropic principle based on the entropy-fluctuation picture is a product of this semantic confusion.

The algorithm targets either a single graphics processing unit (GPU), or a cluster of those, performs all non-trivial computation exclusively on the GPUs, requires the minimal amount of memory to be reasonably expected, scales acceptably with the increase of the number of GPUs available, and guarantees the reproducible, bitwise identical output of the runs repeated over the same input and with the same number of GPUs.

description: We study the formation and propagation of chirped elliptic and solitary waves in cubic-quintic nonlinear Helmholtz (CQNLH) equation. This system describes nonparaxial pulse propagation in a planar waveguide with Kerr-like and quintic nonlinearities along with spatial dispersion originating from the nonparaxial effect that becomes dominant when the conventional slowly varying envelope approximation (SVEA) fails. We first carry out the modulational instability (MI) analysis of a plane wave in this system by employing the linear stability analysis and investigate the influence of different physical parameters on the MI gain spectra. In particular, we show the nonparaxial parameter suppresses the conventional MI gain spectrum and also leads to a nontrivial monotonic increase in the gain spectrum near the tails of the conventional MI band, a qualitatively distinct behaviour from the standard nonlinear Schrödinger (NLS) system. We then study the MI dynamics by direct numerical simulations which demonstrate production of ultra-short nonparaxial pulse trains with internal oscillations and slight distortions at the wings. Following the MI dynamics, we obtain exact elliptic and solitary wave solutions using the integration method by considering physically interesting chirped traveling wave ansatz. In particular, we show that the system features intriguing chirped anti-dark, bright, gray and dark solitary waves depending upon the nature of nonlinearities. We also show that the chirping is inversely proportional to the intensity of the optical wave. Especially, the bright and dark solitary waves exhibit unusual chirping behaviour which will have applications in nonlinear pulse compression process.

Economics of export subsidies under costly and imperfect enforcement

description: The present paper builds on the published literature on agricultural policy analysis under costly and imperfect enforcement by introducing enforcement costs and misrepresentation into the economic analysis of export subsidies. Specifically, the present paper examines the economic causes of cheating on export subsidies and the consequences of enforcement costs and misrepresentation for the welfare effects and the transfer efficiency of this policy instrument. Policy design and implementation is modelled as a sequential game between a government that designs and enforces the policy and the recipients of the payments. Two alternative policy implementation scenarios are considered. In the first scenario, export subsidies are paid to private trading firms while in the second scenario subsidies are paid directly to the producers of the subsidised commodity. Analytical results show that the introduction of enforcement costs and cheating changes the welfare effects of export subsidies and their efficiency in redistributing income to producers. The analysis also shows that, contrary to what is traditionally believed, the incidence of export subsidies depends on the group that is subsidised to export the surplus quantity – the way the policy is implemented. The results provide additional support for the contention that the economic consequences of cheating are highly policy-specific. Finally, the analysis reveals that when the government faces restrictions on either the volume or the value of export subsidies, cheating reduces the distortionary effects of the policy on international markets. This is true irrespective of whether subsidies are paid to trading firms or to producers.

description: Monitoring continental precipitation over Europe with high resolution (2 km, 15 minutes) has been possible since the operational production of the OPERA composites from the European weather radar networks. The OPERA data are the essential input to a hazard assessment tool for identifying localized rainfall-induced flash floods at European scale, and their quality determines the performance of the tool. This paper analyses the OPERA data quality during the warm seasons of 2015-2017 by comparing the estimated rainfall accumulations with the SYNOP rain gauge records over Europe. To compensate the OPERA underestimation, a simple spatially-variable bias adjustment method has been applied. The long-term comparison between the OPERA and gauge point daily rainfall accumulations at the gauge locations shows the benefit of the bias adjustment. Additionally, the daily monitoring shows gradual improvement of the OPERA data year by year. The impact of the quality of the OPERA data for effective flash flood identification is demonstrated for the case of the flash floods that occurred from 29 May to 3 June 2016 in central Europe.

description: Using the Chandra/ACIS-I detector, we have identified an X-ray source (CXOU 132619.7-472910.8) in the globular cluster NGC 5139 with a thermal spectrum identical to that observed from transiently accreting neutron stars in quiescence. The absence of intensity variability on timescales as short as 4 seconds (< 25% rms variability) and as long as 5 years (<50% variability) supports the identification of this source as a neutron star, most likely maintained at a high effective temperature (approximately 1e6 K) by transient accretion from a binary companion. The ability to spectrally identify quiescent neutron stars in globular clusters (where the distance and interstellar column densities are known) opens up new opportunities for precision neutron star radius measurements.

description: Genus Cervonema Wieser 1954
 Emended diagnosis. Sabatieriinae with striate cuticle; fine punctations may be also observed. Anterior and posterior cephalic sensilla in distinctly separate crowns and usually equal in length. Buccal cavity short and undifferentiated. Posterior elongate oesophageal bulb. Cervical region elongate and narrowed, amphids usually set back from cephalic setae, about 2 hd from the anterior, and up to 7 turns. Spicules simple, poorly sclerotized and <2 abd in length, usually ≤ 1 abd. Gubernaculum plate-like, or not observed, apophyses absent. Supplements minute tubular pores or absent. Tail conico-cylindrical.
 Remarks. To date 13 species of Cervonema have been described: C. allometricum Wieser 1954, C. tenuicauda Schuurmans Stekhoven jr. 1950, C. macramphis Jensen 1979, C. jenseni Gourbault 1980, C brevicauda, Gourbault 1980, C. papillatum Jensen 1988, C. deltensis Hope & Zhang 1995, C. minutus (Muthumbi et al. 1997), C. gourbaulti Muthumbi et al. 1997, C. chilensis Chen & Vincx 2000, C. hermani Chen & Vincx 2000, C. shia Chen & Vincx 2000, C. proximamphidu Tchesunov 2000. Table 5 presents a comprehensive comparison of the morphometric characteristics of these species and Table 6 provides the calculated body proportions, such as de Man's ratios. Where measurements were not presented in the original descriptions they are supplemented by measurements made by the authors from the original published figures where possible.
 Here one species, Cervonema pseudodeltensis is described based on male and female specimens, and a further two species are informally described owing to a lack of males. The intention of these informal descriptions is to indicate the presence of additional species and to describe them as best as possible, without males, to allow subsequent researches an ability to compare records. Although for some taxa it is common practise to describe species based on females, it is not so for nematodes. Whilst for the Cervonema the male characters are not very informative to species differentiation, there is a risk of introducing nomenclatural problems, as yet unforeseen, if these species are described based on females only.

description: Earlier studies of the Neoproterozoic magmatism and tectonic evolution in Erguna Massif of NE China are spatially confined to the central and northern parts of the area, but the southwestern part of the massif is poorly studied. This contribution documents new zircon U-Pb geochronology, Lu-Hf isotopic systematics, and whole-rock geochemistry from Neoproterozoic granites in the southwestern part of the area. The aim of this study is to determine the petrogenesis of the granites and further elucidate on the geodynamic setting of Neoproterozoic magmatism in the massif and their geological implications. Syenogranite samples from the region yield LA-ICP-MS U-Pb zircon weighted mean ages of 853 ± 5 Ma and 824 ± 3 Ma, and both dates are evidence for Neoproterozoic magmatism in the southwestern part of the massif. Both syenogranite samples are peraluminous (A/CNK = 1.06–1.43), calc-alkaline with high-K values, and assay 76.06–76.52 wt% SiO2, 1.98–3.20 wt% Na2O, and 4.63–4.77% wt% K2O. The syenogranites’ Chondrite-normalized REE pattern display a ‘gull-wing’ shape, with low (La/Yb)N ratios of 2.28–4.29 and significant negative Eu anomalies of δEu = 0.09–0.19. The syenogranites are characterized by depletion in Ba, Nb, Ta, Sr, P, and Ti and enrichment in Rb, Th, U and K compared to the N-MORB and non-fractionated granites elsewhere in the massif. These geochemical characteristics show that the Neoproterozoic syenogranite plutons in SW Erguna Massif are highly fractionated. Zircons from the granites also have εHf(t) values of +7.68 to −1.48 with corresponding two-stage model ages of ca. 1828 to 1258 Ma, indicating that they formed from the partial melting of a Palaeo- and Mesoproterozoic igneous source in the middle crust. In combination with previously published geological data, it is proposed that the Neoproterozoic granites in the southwestern study area were emplaced in an extensional environment before or during the initial stages of the break-up of the Rodinia.

description: The doping dependence of the superfluid density, r_s, of high-Tc superconductors is usually considered in the context of the Uemura relation, namely Tc proportional to rs, which is generally assumed to apply in the underdoped regime. We show that a modified plot of Tc/Do versus rs, where Do is the maximum d-wave gap at T=0, exhibits universal features that point to an alternative interpretation of the underlying physics. In the underdoped region this plot exhibits the canonical negative curvature expected when a ground-state correlation competes with superconductivity (SC) by opening up a gap in the normal-state DOS. In particular rs is suppressed much faster than Tc/Do or indeed Tc. The pseudogap is found to strongly modify the SC ground state.

description: Persistently active lava lakes show continuous outgassing and open convection over years to decades. Ray Lake, the lava lake at Mount Erebus, Ross Island, Antarctica, maintains long-term, near steady-state behavior in temperature, heat flux, gas flux, lake level, and composition. This activity is superposed by periodic small pulses of gas and hot magma every 5-18 minutes and disrupted by sporadic Strombolian eruptions. The periodic pulses have been attributed to a variety of potential processes including unstable bidirectional flow in the conduit feeding the lake. In contrast to hypotheses invoking a conduit source for the observed periodicity, we test the hypothesis that the behavior could be the result of dynamics within the lake itself, independent of periodic influx from the conduit. We perform numerical simulations of convection in Ray Lake driven by both constant and periodic inflow of gas-rich magma from the conduit to identify whether the two cases have different observational signatures at the surface. Our simulations show dripping diapirs or pulsing plumes leading to observable surface behavior with periodicities in the range of 5-20 minutes. We conclude that a convective speed faster than the inflow speed can result in periodic behavior without requiring periodicity in conduit dynamics. This finding suggests that the surface behavior of lava lakes might be less indicative of volcanic conduit processes in persistently outgassing volcanoes than previously thought, and that dynamics within the lava lake itself may modify or overprint patterns emerging from the conduit.

description: Many astrophysical flows occur in inhomogeneous (clumpy) media. We present results of a numerical study of steady, planar shocks interacting with a system of embedded cylindrical clouds. Our study uses a two-dimensional geometry. Our numerical code uses an adaptive mesh refinement allowing us to achieve sufficiently high resolution both at the largest and the smallest scales. We neglect any radiative losses, heat conduction, and gravitational forces. Detailed analysis of the simulations shows that interaction of embedded inhomogeneities with the shock/postshock wind depends primarily on the thickness of the cloud layer and arrangement of the clouds in the layer. The total cloud mass and the total number of individual clouds is not a significant factor. We define two classes of cloud distributions: thin and thick layers. We define the critical cloud separation along the direction of the flow and perpendicular to it distinguishing between the interacting and noninteracting regimes of cloud evolution. Finally we discuss mass-loading and mixing in such systems.

description: The economic feasibility of fertilizing irrigated grain sorghum with compos ted manure is evaluated using net return budgeting and production function analysis. Although the use of compost is technically feasible, the economic analysis indicates that compost does not comprise a large percentage of the nitrogen source in the profit-maximizing combination with commercial fertilizer.
Magnetic Fields in Star-Forming Molecular Clouds. V. Submillimeter Polarization of the Barnard 1 Dark Cloud

description: We present 850 micron polarimetry from the James Clerk Maxwell Telescope toward several dense cores within the dark cloud Barnard 1 in Perseus. Significant polarized emission is detected from across the mapped area and is not confined to the locations of bright cores. This indicates the presence of aligned grains and hence a component of the magnetic field in the plane of the sky. Polarization vectors detected away from bright cores are strongly aligned at a position angle of ~ 90 degrees (east of north), while vectors associated with bright cores show alignments of varying orientations. There is no direct correlation between the polarization angles measured in earlier optical polarimetry toward Perseus and the polarized submillimeter thermal emission. Depolarization toward high intensities is exhibited, but toward the brightest core reaches a threshold beyond which no further decrease in polarization percentage is measured. The polarized emission data from the interior envelope are compared with previously published OH Zeeman data to estimate the total field strength and orientation under the assumption of a uniform and non-uniform field component in the region. These results are rough estimates only due to the single independent detection of Zeeman splitting toward Barnard 1. The uniform field component is thus calculated to be B(0) = 31 microGauss [+/- (0.52 (north) - 0.01 (east)) - 0.86 (l.o.s.)] in the case where we have assumed the ratio of the dispersion of the line-of-sight field to the field strength to be 0.2.

description: We present the results of a systematic study using the density functional theory (within the local density approximation) of the effects of biaxial strain and composition on the self-diffusion of Si and Ge in SiGe alloys diffusing by a vacancy mechanism. The biaxial strain dependence of the vacancy formation energy was reconfirmed with previous calculations. The effect of biaxial strain on the interaction potential energy between a substitutional Ge atom and a vacancy was calculated. These calculations were used to estimate the change in the activation energy (due to biaxial strain) for the self-diffusion of Si and Ge in Si by a vacancy mechanism. The composition dependence of the vacancy formation energy was calculated. A database of ab initio migration energy barriers for vacancy migration in different local environments was systematically developed by considering the effect of the first nearest neighbor sites explicitly and the effect of the other sites by a mean field approximation. A kinetic Monte Carlo simulation based on the migration energy barrier database was performed to determine the dependence (on the composition)of the activation energy for the diffusion of Si and Ge in SiGe. A detailed study of the variation of the correlation factor with composition and temperature in SiGe was performed using the results of the KMC simulation. These analyses constitute essential building blocks to understand the mechanism of vacancy mediated diffusion processes at the microscopic level.

Apogonichthys taeniopterus

description: Apogonichthys taeniopterus Bleeker, 1860
 Apogonichthys taeniopterus Bleeker, 1860c, is based on two coloured paintings by Castelnau, No. 93 (Fig. 1) and No. 342 (Fig. 2). No specimen has been identified that served as the basis for the painting and the name. Bleeker provided a brief accurate description in Latin and made no additional comments. In his second description of this species, Bleeker (1874) changed two words in an otherwise repeated Latin description. These words were “3” for “4” in reference to the body depth (about 4.3 from the painting) in its length and “vitta” for “fascia”. He provided remarks on characteristics he could not determine, such as number of fin elements, number of scales and an uncertainty of serration on the preopercle. He believed the colour pattern was distinct. In Bleeker’s “Atlas Ichthyologique” (1871–1876: 99) the Latin description reverted to the original description although his remarks were brief with sentences lifted from his 1874 paper. In the latter two publications Bleeker placed this species just after Apogon truncatus Bleeker, 1854.
 Weber & de Beaufort (1929) listed Bleeker’s name as a synonym of Apogon ellioti Day, 1875, pre-empted by Apogon taeniopterus Bennett, 1836. Gon (1996) reviewed the nomenclature of Apogon truncatus in his revision of the species group but did not list or comment on Bleeker’s taeniopterus. Gon’s illustration and Day’s (1875) description and figure of Apogon ellioti agree on most of the diagnostic colour pattern present in Castelnau’s painting. The figure of Apogon truncatus in Bleeker’s Atlas (1871–76, Pl. 41) shows only the distal dark portion of the first dorsal fin. No other markings were present.
 We conclude that Apogonichthys taeniopterus is a junior synonym of Apogon truncatus, agreeing with Weber & de Beaufort. Gon (1996) treated Apogon truncatus in the subgenus Jaydia, now recognized as a genus, removing the homonym conflict with Bennett’s description of Apogon taeniopterus in 1836.
