description: We present a detailed study of a generalised one-dimensional Kronig-Penney model using $δ\text{-}δ'$ potentials. We analyse the band structure and the density of states in two situations. In the first case we consider an infinite array formed by identical $δ\text{-}δ'$ potentials standing at the linear lattice nodes. This case will be known throughout the paper as the one-species hybrid Dirac comb. We investigate the consequences of adding the $δ'$ interaction to the Dirac comb by comparing the band spectra and the density of states of pure Dirac-$δ$ combs and one-species hybrid Dirac combs. Secondly we study the quantum system that arises when the periodic potential is the one obtained from the superposition of two one-species hybrid Dirac combs displaced one with respect to the other and with different couplings. The latter will be known as the two-species hybrid Dirac comb. One of the most remarkable results is the appearance of a curvature change in the band spectrum when the $δ'$ couplings are above a critical value.

 Caliadurgus maestris Alayo, 1969, Poeyana, serie A, vol. 61, p. 17 [Holotype: ♀, CUBA, Oriente (IZAC?)].
 Diagnosis. This species can be recognized by the following unique combination of characters: the integument is orange-reddish with sparse purple reflections (Fig. 5J); the antenna is black, except the scape, which has the same color as the body; the pubescence on the body is short and silver, more abundant in the inner margin of the eyes; the front tibia has a large spine on the dorsal apex; the dorsal face of the hind tibia has scale-like spines; the last tarsal segment of hind leg is without a lateral row of spines; and the wings are uniformly dark with purple reflections. The male of this species is unknown.
 Material examined. DOMINICAN REPUBLIC: 1 ♀, La Vega, Cordillera Central, Loma Casabito, 15.8 km NW, Bonao, 19–02–12N, 70–31–08W, 1455m, evergreen cloud forest, east slope, yellow pan trap, sample 21262, 28.V.2003, J. Rawlins et al. CMNH –370.551.
 Distribution. Cuba, Dominican Republic.
 Host. Unknown.
 Remarks. This species was first described from Cuba by Alayo (1969) and included females only. To our knowledge, the males of this species are unknown. In Alayo's (1969) description, the institution in which the holotype is deposited was not specified, but the holotypes of other species described in his paper were deposited in the Academia de Ciencias de Cuba, Instituto de Zoologia. We believe the type series of C. maestris is at the same institution, although we have not studied these Cuban specimens nor been able to get confirmation. The Dominican Republic specimen differs from the Cuban in having sparse purple reflections on the body, which was not stated in the original description. This is the first record of this species from the Dominican Republic.

Dynamical classical superfluid-insulator transition in a Bose-Einstein condensate on an optical lattice

description: We predict a dynamical classical superfluid-insulator transition in a Bose-Einstein condensate (BEC) trapped in a combined optical and axially-symmetric harmonic potentials initiated by a periodic modulation of the radial trapping potential. The transition is marked by a loss of phase coherence in the BEC and a subsequent destruction of the interference pattern upon free expansion. For a weak modulation of the radial potential the phase coherence is maintained. For a stronger modulation and a longer time of holding in the modulated trap, the phase coherence is destroyed signaling a classical superfluid-insulator transition. The results are illustrated by a complete numerical solution of the axially-symmetric mean-field Gross-Pitaevskii equation for a repulsive BEC. Suggestion for future experiment is made.

description: The regions around the celestial poles offer the ability to find and characterize long-term variables from ground-based observatories. We used multi-year Evryscope data to search for high-amplitude (~5% or greater) variable objects among 160,000 bright stars (Mv < 14.5) near the South Celestial Pole. We developed a machine learning based spectral classifier to identify eclipse and transit candidates with M-dwarf or K-dwarf host stars - and potential low-mass secondary stars or gas giant planets. The large amplitude transit signals from low-mass companions of smaller dwarf host stars lessens the photometric precision and systematics removal requirements necessary for detection, and increases the discoveries from long-term observations with modest light curve precision. The Evryscope is a robotic telescope array that observes the Southern sky continuously at 2-minute cadence, searching for stellar variability, transients, transits around exotic stars and other observationally challenging astrophysical variables. In this study, covering all stars 9 < Mv < 14.5, in declinations -75 to -90 deg, we recover 346 known variables and discover 303 new variables, including 168 eclipsing binaries. We characterize the discoveries and provide the amplitudes, periods, and variability type. A 1.7 Jupiter radius planet candidate with a late K-dwarf primary was found and the transit signal was verified with the PROMPT telescope network. Further followup revealed this object to be a likely grazing eclipsing binary system with nearly identical primary and secondary K5 stars. Radial velocity measurements from the Goodman Spectrograph on the 4.1 meter SOAR telescope of the likely-lowest-mass targets reveal that six of the eclipsing binary discoveries are low-mass (.06 - .37 solar mass) secondaries with K-dwarf primaries, strong candidates for precision mass-radius measurements.

description: This article surveys the physics of systems proximate to Mott insulators, and presents a classification using conventional and topological order parameters. This classification offers a valuable perspective on a variety of conducting correlated electron systems, from the cuprate superconductors to the heavy fermion compounds. Connections are drawn, and distinctions made, between collinear/non-collinear magnetic order, bond order, neutral spin 1/2 excitations in insulators, electron Fermi surfaces which violate Luttinger's theorem, fractionalization of the electron, and the fractionalization of bosonic collective modes. Two distinct categories of Z_2 gauge theories are used to describe the interplay of these orders. Experimental implications for the cuprates are briefly noted, but these appear in more detail in a companion review article (S. Sachdev, cond-mat/0211005).

Buddhist Architecture in the Western Himalayas_Dimensioned plan drawings of Basgo
Creators: name: Auer, Carmen
Publisher: name: Graz University of Technology
Year: 2024

description: For more than two decades and within the framework of various field research projects, an extensive collection of research material on Buddhist architecture in the Western Himalayas has been compiled at Graz University of Technology. The material documents individual temples, temple complexes and votive buildings associated with the second wave of the spread of Buddhism in Tibet from the 10th century onwards.

These preserved buildings are the most significant source for architectural research as well as other fields of research and scholarship, such as Art History and Tibetology. The research results are intended to elucidate the contextual relationships and particularities of Buddhist architecture in Nepal, northern India and western Tibet. They contribute to creating a comprehensive typology of early Buddhist architecture in the Western Himalayas. 

In addition to the material provided on our website, we provide dimensioned plan drawings of selected examples, hence making the architectural documentation more accessible to a broader audience.

description: Given a closed complex manifold $X$ of even dimension, we develop a systematic (vertex) algebraic approach to study the rational orbifold cohomology rings $\orbsym$ of the symmetric products. We present constructions and establish results on the rings $\orbsym$ including two sets of ring generators, universality and stability, as well as connections with vertex operators and W algebras. These are independent of but parallel to the main results on the cohomology rings of the Hilbert schemes of points on surfaces as developed in our earlier works joint with W.-P. Li. We introduce a deformation of the orbifold cup product and explain how it is reflected in terms of modification of vertex operators in the symmetric product case. As a corollary, we obtain a new proof of the isomorphism between the rational cohomology ring of Hilbert schemes and the ring $\orbsym$ (after some modification of signs), when X is a projective surface with a numerically trivial canonical class; we show that no sign modification is needed if both cohomology rings use complex coefficients.

 Type species Dipogon populator Fox, 1897, by original designation and monotypy.
 Remarks. Species of this cosmopolitan genus are restricted to wooded areas. Females nest in twigs or aerial cavities. These wasps are rarely taken by conventional collecting methods, and several of the species are known from only a few specimens (Evans & Leatherman 2002). Evans (1972) described one species from Dominica, the first been recorded to Caribbean. This is the first time that Dipogon is recorded from the Dominican Republic.

X-ray and Optical Variations in the Classical Be Star gamma Cas

description: gamma Cas (B0.5e) is known to be a unique X-ray source because ot its moderate L_x, hard X-ray spectrum, and light curve punctuated by ubiquitous flares and slow undulations. Its X-ray peculiarities have led to a controversy concerning their origin: either from wind infall onto a putative degenerate companion, as for typical Be/X-ray binaries, or from the Be star per se. Recent progress has been made to address this: (1) the discovery that gamma Cas is an eccentric binary system (P = 203.59 d) with unknown secondary type, (2) the accumulation of RXTE data at 9 epochs in 1996-2000, and (3) the collation of robotic telescope B, V-band photometric observations over 4 seasons. The latter show a 3%, cyclical flux variation with cycle lengths 55-93 days. We find that X-ray fluxes at all 9 epochs show random variations with orbital phase. This contradicts the binary accretion model, which predicts a substantial modulation. However,these fluxes correlate well with the cyclical optical variations. Also, the 6 flux measurements in 2000 closely track the interpolated optical variations between the 2000 and 2001 observing seasons. Since the optical variations represent a far greater energy than that emitted as X-rays, the optical variability cannot arise from X-ray reprocessing. However, the strong correlation between the two suggests that they are driven by a common mechanism. We propose that this mechanism is a cyclical magnetic dynamo excited by a Balbus-Hawley instability located within the inner part of the circumstellar disk. In our model, variations in the field strength directly produce the changes in the magnetically related X-ray activity. Turbulence associated with the dynamo results in changes to the density distribution within the disk and creates the observed optical variations.

description: We report temperature (T) dependence (2-330 K) of DC and AC magnetization (M), isothermal remnant magnetization (M_IRM), heat capacity (C), electrical resistivity (rho), and magnetoresistance (MR) of a ternary intermetallic compound, Gd4PtAl, crystallizing in a cubic (space group F-43m) structure. In this structure, there are three sites for the rare-earth. The magnetization data reveal that, in addition to a magnetic transition at 64 K, there is another magnetic feature below 20 K. The C(T) data reveal an upturn below 64 K, shifting to a lower temperature with increasing field, which establishes that the onset of magnetic order is of an antiferromagnetic type. However, there is no worthwhile feature near 20 K in the C(T) curve. AC susceptibility peak undergoes an observable change with frequency and, in particular, the peak around 20 K gets suppressed with the application of a dc magnetic field; in addition, M_IRM undergoes a slow decay with time and isothermal M exhibits low-field hysteresis below 20 K only, which is typical of spin-glasses. The results overall suggest that this compound is a reentrant spin-glass in zero-field. There are experimental signatures pointing to the existence of both antiferromagnetic and ferromagnetic components, competing with the variation of temperature and magnetic field, as a result of which electrical and magnetoresistance behaviors are peculiar. The results overall suggest this compound exhibits interesting magnetic and transport properties.

Our results are consistent with results obtained by other groups, suggesting a best-fit FRW Universe with $\omegam = 1 -λ\approx 0.3$ and $H_0 \approx 75$ km/sec/Mpc. We point out some potential problems with this currently popular model.

Empirical study results showed that compared with values-related brand crisis, performance-related brand crisis had a more significant effect on consumers' perceived competence-based trust and there were no significant differences in the negative effects of two types of brand crisises on consumers’ perceived benevolence-based trust. In addition, consumers’ perceived competence-based and benevolence-based trust had a positive effect on brand attitude and consistency of negative word of mouth played a moderating role in the relationship between brand crisis type and brand attitude.

We further describe a numerical method to compute these $n$-widths approximately, and prove that this method is superconvergent. Based on our numerical results we formulate a conjecture on the asymptotic behaviour of the $n$-widths. Finally we describe how the numerical method can be used to compute the breakpoints of the optimal spline spaces of Melkman and Micchelli, which have recently received renewed attention in the field of Isogeometric Analysis.

description: Organic foods are one of the most rapidly growing sectors of the retail food market. This study applies a hedonic model to 2004-10 Nielsen Homescan data to estimate the organic price premiums for 17 products. Eggs and dairy products generally have the highest premiums, while fresh produce has the widest spread of premiums (ranging from 7 percent of the nonorganic price for spinach to 60 percent for salad mix). Processed food premiums range from 22 percent for granola to 54 percent for canned beans. The strong organic premiums, combined with increased sales, suggest that there is continued room for growth in the organic supply.
General Relativistic Geodetic Spin Precession in Binary Pulsar B1913+16: Mapping the Emission Beam in Two Dimensions

description: We have carefully measured the pulse profile of the binary pulsar PSR B1913+16 at 21 cm wavelength for twenty years, in order to search for variations that result from general relativistic geodetic precession of the spin axis. The profile width is found to decrease with time in its inner regions, while staying essentially constant on its outer skirts. We fit these data to a model of the beam shape and precession geometry. Four equivalent solutions are found, but evolutionary considerations and polarization data select a single preferred model. While the current data sample only a limited range of latitudes owing to the long precessional cycle, the preferred model shows a beam elongated in the latitude direction and hourglass--shaped.

description: A prominent issue related to land-use changes in Brazil is the westward expansion of agriculture into the country’s frontier region, which includes the surrounding Cerrados savannah. The conversion of range, pasture, and other land into cropland in Brazil is due to rising domestic and international food demand but is also a consequence of ethanol production and policies that have increased the demand for sugarcane (ethanol feedstock). Because the supply and demand for ethanol are inexorably linked to that of petroleum, oil prices can affect production and land-use decisions for ethanol feedstocks and related agricultural commodities. This study examines the effects of longrun changes in oil prices on ethanol production in Brazil and resulting cropping patterns. Given a sustained fall in oil prices, ethanol use would be expected to fall, leading to a decrease in area planted to sugarcane and an increase in land available for other agricultural commodities. However, a sustained increase in oil prices would be expected to increase the incentives to produce ethanol, thereby expanding sugarcane production and planting area. Given Brazil’s dominant position in multiple global commodity export markets, adjustments to output and exports would lead to changes in world prices.

description: We study the nucleon's partonic angular momentum (AM) content at peripheral transverse distances $b = \mathcal{O}(M_π^{-1})$, where the structure is governed by chiral dynamics. We compute the nucleon form factors of the energy-momentum tensor in chiral effective field theory (ChEFT) and construct the transverse densities of AM at fixed light-front time. In the periphery the spin density is suppressed, and the AM is predominantly orbital. In the first-quantized representation of ChEFT in light-front form, the field-theoretical AM density coincides with the quantum-mechanical orbital AM density of the soft pions in the nucleon's periphery.

Results from two implicit solvent models are compared with each other and with that from simulations in gas phase. While the helix-coil transition is in all three models a true thermodynamic phase transition, we find that its strength is reduced by the protein-solvent interaction term. The order of the helix-coil transition depends on the details of the solvation term.

 Type species Entypus ochrocerus Dahlbom, 1843, by monotypy.
 Remarks. Only one species of Entypus was present in our sample: E. ochrocerus Dahlbom. In the literature, however, three other names of Entypus are associated with the Dominican Republic fauna: E. caeruleus (Linneus), E. sulphureicornis (Palisot de Beauvois), and E. manni (Banks). Entypus caeruleus and E. sulphureicornis were recorded from Hispaniola by Perez-Gelabert (2008) as Pepsis species. Day (1979) formally transferred the first name to Entypus, while E. sulphureicornis was transferred by Vardy (2005) to Entypus based on a personal communication from Day. Both names do not have recent citations other than Perez-Gelabert (2008) and we do not include them in our key for the Dominican Republic Pompilidae. Entypus manni was first described as Cryptocheilus by Banks (1928), who provided a detailed description.
 Perez-Gelabert (2008) did not have any new material and his work was based on literature only. As the material we studied for this review contained no individuals of E. caeruleus, E. sulphureicorni, or E. manni, it remains uncertain whether these species are truly present in the Dominican Republic. Further studies of Entypus in the Caribbean are needed.

description: Understanding where U.S. households acquire food, what they acquire, and what they pay is essential to identifying which food and nutrition policies might improve diet quality. USDA’s National Household Food Acquisition and Purchase Survey (FoodAPS) provides a complete picture of where households acquire food, what they acquire, and how much they pay during a 7-day period in 2012. Nearly all households acquire food at least once during the week; 87 percent visited large grocery stores and supermarkets, and 85 percent visited restaurants and other eating places at least once. Households acquired food at no cost on 22 percent of occasions, and these events occurred mainly at food pantries/Meals on Wheels, schools, meals with family or friends, community events, and workplaces.

description: We say that a subset of $\mathbb{P}^n(\mathbb{R})$ is maximally singular if its contains points with $\mathbb{Q}$-linearly independent homogenous coordinates whose uniform exponent of simultaneous rational approximation is equal to $1$, the maximal possible value. In this paper, we give a criterion which provides many such sets including Grassmannians. We also recover a result of the author and Roy about a class of quadratic hypersurfaces.

description: The U.S. Department of Agriculture’s (USDA) National Household Food Acquisition and Purchase Survey (FoodAPS) is the first nationally representative household survey to collect data on foods purchased or acquired during a survey week, producing results that are both nationally representative and representative of Supplemental Nutrition Assistance Program (SNAP) participants as well as of low-income non-SNAP households. In order to assess the quality of FoodAPS data, this report compares estimates from FoodAPS to estimates from other national-level food-related surveys, examining: (1) general demographic and socio-economic characteristics; (2) food expenditures; (3) food security; (4) SNAP participation and income; and (5) diet behavior and health. FoodAPS estimates of total, food-at-home (FAH) spending are greater than estimates from the Consumer Expenditure Survey (CE) but less than those from the National Health and Nutrition Examination Survey (NHANES). Compared to other national-level surveys, FoodAPS estimates a greater share of households with low or very low food security.

description: We investigate the effects of gravitational lensing due to intervening galaxies on the recently discovered Type Ia supernova at z=1.7, SN1997ff, in the Hubble Deep Field North. We find that it is possible to obtain a wide range of magnifications by varying the mass and/or the velocity dispersion normalization of the lensing galaxies. In order to be able to use SN1997ff to constrain the redshift-distance relation, very detailed modeling of the galaxies to control the systematic effects from lensing is necessary. Thus we argue, that based on our current limited knowledge of the lensing galaxies, it is difficult to use SN1997ff to constrain the values of Omega_M and Omega_Lambda, or even to place severe limits on grey dust obscuration or luminosity evolution of Type Ia supernovae.

description: Launching in 2028, ESA's Atmospheric Remote-sensing Exoplanet Large-survey (ARIEL) survey of $\sim$1000 transiting exoplanets will build on the legacies of Kepler and TESS and complement JWST by placing its high precision exoplanet observations into a large, statistically-significant planetary population context. With continuous 0.5--7.8~$μ$m coverage from both FGS (0.50--0.55, 0.8--1.0, and 1.0--1.2~$μ$m photometry; 1.25--1.95~$μ$m spectroscopy) and AIRS (1.95--7.80~$μ$m spectroscopy), ARIEL will determine atmospheric compositions and probe planetary formation histories during its 3.5-year mission. NASA's proposed Contribution to ARIEL Spectroscopy of Exoplanets (CASE) would be a subsystem of ARIEL's FGS instrument consisting of two visible-to-infrared detectors, associated readout electronics, and thermal control hardware. FGS, to be built by the Polish Academy of Sciences' Space Research Centre, will provide both fine guiding and visible to near-infrared photometry and spectroscopy, providing powerful diagnostics of atmospheric aerosol contribution and planetary albedo, which play a crucial role in establishing planetary energy balance. The CASE team presents here an independent study of the capabilities of ARIEL to measure exoplanetary metallicities, which probe the conditions of planet formation, and FGS to measure scattering spectral slopes, which indicate if an exoplanet has atmospheric aerosols (clouds and hazes), and geometric albedos, which help establish planetary climate. Our design reference mission simulations show that ARIEL could measure the mass-metallicity relationship of its 1000-planet single-visit sample to $>7.5σ$ and that FGS could distinguish between clear, cloudy, and hazy skies and constrain an exoplanet's atmospheric aerosol composition to $>5σ$ for hundreds of targets, providing statistically-transformative science for exoplanet atmospheres.

The Structure and Dynamics of Luminous and Dark Matter in the Early-Type Lens Galaxy of 0047-281 at z=0.485

description: We have measured the kinematic profile of the early-type (E/S0) lens galaxy in the system 0047-281 (z=0.485) with the {\sl Echelle Spectrograph and Imager} (ESI) on the W.M. Keck--II Telescope, as part of the {\sl Lenses Structure and Dynamics (LSD) Survey}. The central velocity dispersion is σ=229\pm 15 \kms, and the dispersion profile is nearly flat to beyond one effective radius (R_e). Surface photometry of the lens galaxy is measured from {\sl Hubble Space Telescope} images. From the offset from the local Fundamental Plane (FP), we measure an evolution of the effective mass-to-light ratio of Δ\log M/L_B=-0.37\pm0.06 between z=0 and z=0.485, consistent with the observed evolution of field E/S0 galaxies. (We assume h_{65}=1,Ω_{\rm m}=0.3 and Ω_Λ=0.7 throughout.) Gravitational lens models provide a mass of M_{\rmE}=(4.06\pm0.20)\times 10^{11} h_{65}^{-1}M_\odot inside the Einstein radius of R_{\rm E}=(8.70\pm0.07) h_{65}^{-1} kpc. This allows us to break the degeneracy between velocity anisotropy and density profile, typical of dynamical models for E/S0 galaxies. We find that constant M/L model, even with strongly tangential anisotropy of the stellar velocity ellipsoid, are excluded at >99.9%CL. The total mass distribution inside R_{\rm E} can be described by a single power-law density profile, ρ_t\propto r^{-γ'}, with an effective slope γ'=1.90^{+0.05}_{-0.23} (68%CL; \pm0.1 systematic error). Two-component models yield an upper limit (68% CL) of γ\le 1.55(1.12) on the power-law slope of the dark-matter density profile and a projected dark-matter mass fraction of 0.41(0.54)^{+0.15}_{-0.05}(^{+0.09}_{-0.06}) (68% CL) inside R_{\rm E}, for Osipkov--Merritt models with anisotropy radius r_i=\infty(R_e).

description: Hemipepsis Dahlbom, 1843
 Type species Hemipepsis capensis Dahlbom, 1843, designated by Ashmead 1900.
 Remarks. Our record for this genus is based on literature only. Hemipepsis has not been reported from Cuba (Alayo 1969, 1976), Puerto Rico (Snelling & Torres 2004), or Dominica (Evans 1972). The only record of this genus in the Caribbean area is based on the type locality of the following species.

description: We present a model for compressible sub-Alfvenic isothermal magnetohydrodynamic (MHD) turbulence in low-beta plasmas and numerically test it. We separate MHD fluctuations into 3 distinct families - Alfven, slow, and fast modes. We find that, production of slow and fast modes by Alfvenic turbulence is suppressed. As a result, Alfven modes in compressible regime exhibit scalings and anisotropy similar to those in incompressible regime. Slow modes passively mimic Alfven modes. However, fast modes show isotropy and a scaling similar to acoustic turbulence.

description: Fruit flies decrease economic percentage of Pakistan by damaging variety of fruits and vegetables and reduce agricultural production. Eleven Species of fruit flies are recorded from Pakistan, but three of which Bactrocera dorsalis, Bactrocera cucurbitae , Bactrocera zonata that attack on apple, mango, beer, guava, musk melon, bitter ground and snake ground are serious pest species. In this research work Laboratory studies were carried out in Ayub Agriculture Research Institute Faisalabad to check efficacy of different insecticides and plant extracts after the time intervals of 6, 12, 24 and 48 hours against peach fruit fly on guava fruit. Emerging adult flies were used in the experiment. Six insecticides viz., Corajin (DU PONT ®/20 EC) Imidacloprid (Crown ®/20 SL) Aceta maprid (Admire ®/20 SL) Steward (DU PONT ®/12.5 EC) Flufenoxuron (Cascade®/05 ES) and NitenPyramid (Capstar®/10 SL) at their recommended doses and two botanical extracts viz ., Neem seed oil and kur-tuma fruit extract were used for peach fruit fly. The order of toxicity on the basis of mortality after 48 hours was recorded as Coragen > Steward > Flufenoxuron > Acetamiprid > Niten pyramid > Imidacloprid > Neem seed oil > Kor-tuma fruit extract.

Pepsis

description: Pepsis Fabricius, 1804
 Type species Pepsis stellata Fabricius, 1793, designated by Latreille 1810.
 Remarks. The following species of Pepsis were represented in our studied sample: P. marginata Palisot de Beauvois, P. rubra (Drury), and P. ruficornis (Fabricius). Perez-Gelabert (2008), however, recorded additional species for the Hisponiola Island: Pepsis cassiope Mocsáry, P. caerulea (Linnaeus), P. nana Mocsáry, P. sericans Lepeletier, and P. sulphuricornis Palisot de Beauvois.
 There are several issues concerning the distribution and validity of the species recorded by Perez-Gelabert (2008). Pepsis caerulea and P. sulphuricornis are no longer recognized as Pepsis. These species were classified as Entypus by Day (1979) (see Entypus section). Pepsis cassiope is found from the Southern USA to Bolivia, Colombia east through Guyana to the Amazon delta, and the southeast coast of Brazil (Vardy 2002). The single records for Mexico and Dominican Republic are dubious (Vardy 2002). As pointed by Perez-Gelabert (2008), P. nana is found only in South America in the eastern Andes, and the specimens recorded from Haiti are probably mislabeled (Vardy 2005). Pepsis sericans is the senior synonym of a complex of names that includes Pepsis domingensis Lepeletier and its variaties (Vardy 2000). Although P. domingensis had been described from Santo Domingo, Dominican Republic, Vardy (2000) stated that the distribution of P. sericans is limited to Cuba and the record of this species from the Dominican Republic is also dubious.
 Because our study did not reveal any of these species in the Dominican Republic, because Pepsis was recently reviewed, and because these species have dubious records attributed to the Dominican Republic, P. cassiope, P. nana, and P. sericans were not included in our key nor in our list of species of the Dominican Republic Pompilidae.
