description: Cell-free massive MIMO is one of the key technologies for future wireless communications, in which users are simultaneously and jointly served by all access points (APs). In this paper, we investigate the minimum mean square error (MMSE) estimation of effective channel coefficients in cell-free massive MIMO systems with massive connectivity. To facilitate the theoretical analysis, only single measurement vector (SMV) based MMSE estimation is considered in this paper, i.e., the MMSE estimation is performed based on the received pilot signals at each AP separately. Inspired by the decoupling principle of replica symmetric postulated MMSE estimation of sparse signal vectors with independent and identically distributed (i.i.d.) non-zero components, we develop the corresponding decoupling principle for the SMV based MMSE estimation of sparse signal vectors with independent and non-identically distributed (i.n.i.d.) non-zero components, which plays a key role in the theoretical analysis of SMV based MMSE estimation of the effective channel coefficients in cell-free massive MIMO systems with massive connectivity. Subsequently, based on the obtained decoupling principle of MMSE estimation, likelihood ratio test and the optimal fusion rule, we perform user activity detection based on the received pilot signals at only one AP, or cooperation among the entire set of APs for centralized or distributed detection. Via theoretical analysis, we show that the error probabilities of both centralized and distributed detection tend to zero when the number of APs tends to infinity while the asymptotic ratio between the number of users and pilots is kept constant. We also investigate the asymptotic behavior of oracle estimation in cell-free massive MIMO systems with massive connectivity via random matrix theory.

description: The popular Biometric used to authenticate a person is Fingerprint which is unique and permanent throughout a person's life. A minutia matching is widely used for fingerprint recognition and can be classified as ridge ending and ridge bifurcation. In this paper we projected Fingerprint Recognition using Minutia Score Matching method (FRMSM). For Fingerprint thinning, the Block Filter is used, which scans the image at the boundary to preserves the quality of the image and extract the minutiae from the thinned image. The false matching ratio is better compared to the existing algorithm.

description: Howickia nudistylus Marshall sp. nov.
(Fig. 45)
 Description. Colour: Head pale reddish except for silvery frontal strips. General colour dull pale brown. Tarsi pale yellow to white, fore and hind tarsi paler than mid tarsi. Face entirely pale microtrichose.
Head: Interfrontal bristles in 2 pairs, lower pair minute. One large orbital bristle, similar in size to outer vertical bristle. Ocelli small but distinct. Eye 2.5X genal height. Vibrissa strong; subvibrissa weak or absent. Arista with long hairs, hairs twice as long as width of first aristomere.
Thorax: Scutellum microtrichose, 3.0X as wide as long; basal marginal bristles short, apical bristles broken off unique type. Wing rudiment flat, slightly longer than scutellum, microtrichose, anterior half ringed by a loop vein. Halter fully developed, pale.
 Male abdomen: Sternite 5 subequal to sternite 4, slightly paler medially but otherwise unmodified; sternite 3 as long as sternites 4 and 5 combined. Subanal plate damaged on unique type. Surstylus narrowly triangular, tapering posteriorly and with irregular ventral surface and only small setae. Distiphallus narrow, tubular. Postgonites strongly bent posteriorly, narrow in distal portion as in H. mercurialis.
Female unknown.
 Type material. Holotype (male, NZAC, debu00127402): North Island, Te Paki, forest litter, 6.Dec.1984, N.O. Mitchell. The internal genitalia plus the subepandrial sclerite and surstyli have been detached from the epandrium on this specimen so some characters (cerci, subanal plate) are obscured.
 Etymology. The specific name refers to the characteristically shaped surstylus, which lacks the stout ventral bristle found in closely related species.
 Comments. The strongly bent postgonite is similar to that of H. mercurialis and H. bicolor. These three species are certainly closely related and also share similar wing rudiments and a fused, capsule-like tergites 1–3. Howickia nudistylus is described on the basis of a single somewhat damaged specimen, but several characters, especially the distinctive surstylus, distinguish it from the other two species in the clade.

description: We report the results of a Submillimeter Array (SMA) interferometric observation of 21-micron source IRAS 07134+1005 in the CO J=3-2 line. In order to determine the morpho-kinematic properties of the molecular envelope of the object, we constructed a model using the Shape software to model the observed CO map. We find that the molecular gas component of the envelopes can be interpreted as a geometrically thick expanding torus with an expanding velocity of 8 km/s. The inner and outer radii of the torus determined by fitting Shape models are 1.2" and 3.0", respectively. The inner radius is consistent with the previous values determined by radiative transfer modeling of the spectral energy distribution and mid-infrared imaging of the dust component. The radii and expansion velocity of the torus suggest that the central star has left the asymptotic giant branch about 1140-1710 years ago, and that the duration of the equatorial enhanced mass loss is about 2560-3130 years. From the absence of an observed jet, we suggest that the formation of a bipolar outflow may lack behind in time from the creation of the equatorial torus.

Wide-field VLBI imaging and astrometry and prospects for an Italian VLBI network including the Sardinia Radio Telescope

description: In this thesis the use of widefield imaging techniques and VLBI observations with a limited number of antennas are explored.

I present techniques to efficiently and accurately image extremely large UV datasets. Very large VLBI datasets must be reduced into multiple, smaller datasets if today’s imaging algorithms are to be used to image them. I present a procedure for accurately shifting the phase centre of a visibility dataset. This procedure has been thoroughly tested and found to be almost two orders of magnitude more accurate than existing techniques. Errors have been found at the level of one part in 1.1 million. These are unlikely to be measurable except in the very largest UV datasets.

Results of a four-station VLBI observation of a field containing multiple sources are presented. A 13 gigapixel image was constructed to search for sources across the entire primary beam of the array by generating over 700 smaller UV datasets.  The source 1320+299A was detected and its astrometric position with respect to the calibrator J1329+3154 is presented. Various techniques for phase calibration and imaging across this field are explored including using the detected source as an in-beam calibrator and peeling of distant confusing sources from VLBI visibility datasets.

A range of issues pertaining to wide-field VLBI have been explored including; parameterising the wide-field performance of VLBI arrays; estimating the sensitivity across the primary beam both for homogeneous and heterogeneous arrays; applying techniques such as mosaicing and primary beam correction to VLBI observations; quantifying the effects of time-average and bandwidth smearing; and calibration and imaging of wide-field VLBI datasets.  The performance of a computer cluster at the Istituto di Radioastronomia in Bologna has been characterised with regard to its ability to correlate using the DiFX software correlator. Using existing software it was possible to characterise the network speed particularly for MPI applications. The capabilities of the DiFX software correlator, running on this cluster, were measured for a range of observation parameters and were shown to be commensurate with the generic performance parameters measured.

The feasibility of an Italian VLBI array has been explored, with discussion of the infrastructure required, the performance of such an array, possible collaborations, and science which could be achieved.

Results from a 22 GHz calibrator survey are also presented. 21 out of 33 sources were detected on a single baseline between two Italian antennas (Medicina to Noto).

The results and discussions presented in this thesis suggest that wide-field VLBI is a technique whose time has finally come. Prospects for exciting new science are discussed in the final chapter.

description: The fetal electrocardiogram (fECG) was first recorded from the maternal abdominal surface in the early 1900s. During the past fifty years, the most advanced electronics technologies and signal processing algorithms have been used to convert noninvasive fetal electrocardiography into a reliable technology for fetal cardiac monitoring. In this chapter, the major signal processing techniques, which have been developed for the modeling, extraction and analysis of the fECG from noninvasive maternal abdominal recordings are reviewed and compared with one another in detail. The major topics of the chapter include: 1) the electrophysiology of the fECG from the signal processing viewpoint, 2) the mathematical model of the maternal volume conduction media and the waveform models of the fECG acquired from body surface leads, 3) the signal acquisition requirements, 4) model-based techniques for fECG noise and interference cancellation, including adaptive filters and semi-blind source separation techniques, and 5) recent algorithmic advances for fetal motion tracking and online fECG extraction from few number of channels.
Gibbs Distribution Based Antenna Splitting and User Scheduling in Full Duplex Massive MIMO Systems

description: A Gibbs distribution based combinatorial optimization algorithm for joint antenna splitting and user scheduling problem in full duplex massive multiple-input multiple-output (MIMO) system is proposed in this paper. The optimal solution of this problem can be determined by exhaustive search. However, the complexity of this approach becomes prohibitive in practice when the sample space is large, which is usually the case in massive MIMO systems. Our algorithm overcomes this drawback by converting the original problem into a Kullback-Leibler (KL) divergence minimization problem, and solving it through a related dynamical system via a stochastic gradient descent method. Using this approach, we improve the spectral efficiency (SE) of the system by performing joint antenna splitting and user scheduling. Additionally, numerical results show that the SE curves obtained with our proposed algorithm overlap with the curves achieved by exhaustive search for user scheduling.

description: Anaphylaxis is a vital systemic allergic reaction. A rapid diagnosis of anaphylaxis is lifesaving. In most cases, nurses are the first to encounter and intervene in anaphylaxis. Therefore, they have a vital responsibility in such cases. The aim of this study is to create a questionnaire and evaluate the anaphylaxis knowledge levels of pediatric nurses. This is a descriptive type of study. The study took place in Turkey. 80 pediatric nurses who work in pediatric intensive care, neonatal intensive care, child service, and pediatric emergency service participated in the study. The sociodemographic data collection form and the anaphylaxis knowledge level assessment form was used for the study. ANOVA and t-test are used to evaluate the data. The average anaphylaxis knowledge score of the pediatric nurses was found 12.61 ± 2.61, therefore it’s moderate. The reliability of the questionnaire was high. Knowledge levels were moderately sufficient in diagnoses and insufficient in treatment and follow-up. Considering how critical anaphylaxis is, the moderately sufficient and insufficient knowledge levels are not substantial and should be increased advancedly. The questionnaire created for this study can be used in future studies. Health institutions should plan training regarding anaphylaxis and recompose anaphylaxis training in general, elaborate treatment and follow-up, and assess pediatric nurses’ knowledge periodically.

description: In this paper, we propose self-supervised speaker representation learning strategies, which comprise of a bootstrap equilibrium speaker representation learning in the front-end and an uncertainty-aware probabilistic speaker embedding training in the back-end. In the front-end stage, we learn the speaker representations via the bootstrap training scheme with the uniformity regularization term. In the back-end stage, the probabilistic speaker embeddings are estimated by maximizing the mutual likelihood score between the speech samples belonging to the same speaker, which provide not only speaker representations but also data uncertainty. Experimental results show that the proposed bootstrap equilibrium training strategy can effectively help learn the speaker representations and outperforms the conventional methods based on contrastive learning. Also, we demonstrate that the integrated two-stage framework further improves the speaker verification performance on the VoxCeleb1 test set in terms of EER and MinDCF.

Neuroprotective strategies against neurodegeneration in cellular model systems

Subjects: BIO/09 Fisiologia

description: In the present study we analyzed new neuroprotective therapeutical strategies in PD (Parkinson’s disease) and AD (Alzheimer’s disease). Current therapeutic strategies for treating PD and AD offer mainly transient symptomatic relief but it is still impossible to block the loss of neuron and then the progression of PD and AD. There is considerable consensus that the increased production and/or aggregation of α- synuclein (α-syn) and β-amyloid peptide (Aβ), plays a central role in the pathogenesis of PD, related synucleinopathies and AD. Therefore, we identified antiamyloidogenic compounds and we tested their effect as neuroprotective drug-like molecules against α-syn and β-amyloid cytotoxicity in PC12. Herein, we show that two nitro-catechol compounds (entacapone and tolcapone) and 5 cathecol-containing compounds (dopamine, pyrogallol, gallic acid, caffeic acid and quercetin) with antioxidant and anti-inflammatory properties, are potent inhibitors of α-syn and β-amyloid oligomerization and fibrillization. Subsequently, we show that the inhibition of α-syn
and β-amyloid oligomerization and fibrillization is correlated with the neuroprotection of these compounds against the α-syn and β-amyloid-induced cytotoxicity in PC12. Finally, we focused on the study of the neuroprotective role of microglia and on the
possibility that the neuroprotection properties of these cells could be use as therapeutical strategy in PD and AD. Here, we have used an in vitro model to
demonstrate neuroprotection of a 48 h-microglial conditioned medium (MCM) towards cerebellar granule neurons (CGNs) challenged with the neurotoxin 6-hydroxydopamine (6-OHDA), which induces a Parkinson-like neurodegeneration,
with Aβ42, which induces a Alzheimer-like neurodegeneration, and glutamate, involved in the major neurodegenerative diseases. We show that MCM nearly completely protects CGNs from 6-OHDA neurotoxicity, partially from glutamate excitotoxicity but not from Aβ42 toxin.

description: Many cellular processes require a polarization axis which generally initially emerges as an inhomogeneous distribution of molecular markers in the cell. We present a simple analytical model of a general mechanism of cell polarization taking into account the positive feedback due to the coupled dynamics of molecular markers and cytoskeleton filaments. We find that the geometry of the organization of cytoskeleton filaments, nucleated on the membrane (e.g., cortical actin) or from a center in the cytoplasm (e.g., microtubule asters), dictates whether the system is capable of spontaneous polarization or polarizes only in response to external asymmetric signals. Our model also captures the main features of recent experiments of cell polarization in two considerably different biological systems, namely, mating budding yeast and neuron growth cones.

Φασματοσκοπία υπερύθρου

description: Οι τανίνες είναι οι βασικότερες πολυφαινόλες που συναντώνται στους οίνους, κυρίως στους ερυθρούς αλλά είναι παρούσες και στους λευκούς. Η ανάλυση τους είναι σημαντική διότι συμβάλλουν στην διαμόρφωση διαφόρων οργανοληπτικών χαρακτηριστικών των οίνων, όπως χρώμα, γεύση και αίσθηση στόματος. Παρουσιάζουν, επίσης, αντιοξειδωτική δράση και συμβάλλουν και στην παλαίωση. Συνεπώς, απαιτείται ένας γρήγορος και αποτελεσματικός τρόπος για την πραγματοποίηση των αναλύσεων. Μια μέθοδος που έχει αναπτυχθεί τα τελευταία χρόνια και έχει ήδη βρει εφαρμογή στον τομέα της οινολογίας είναι η χρήση φασματοσκοπίας υπερύθρου μετασχηματισμού Fourier (Fourier Transform Infrared Spectroscopy – FTIR). Η FTIR προσφέρει την δυνατότητα ταχέων και υψηλούς ακρίβειας αναλύσεων πολλών συστατικών ταυτόχρονα χωρίς να απαιτείται κάποια ιδιαίτερη προετοιμασία και χωρίς τοξικά απόβλητα. Στη συγκεκριμένη έρευνα έγινε μια προσπάθεια διερεύνησης της δυνατότητας χρήσης FTIR φασματοσκοπίας σε οίνους ερυθρούς και λευκούς με διαφορετικές συγκεντρώσεις τανινών. Σκοπός ήταν ο έλεγχος καταλληλότητας χρήσεως της FTIR για τον προσδιορισμό της συγκέντρωσης τανινών σε οίνους. Οι αναλύσεις έγιναν στην περιοχή MIR (4000 – 400cm-1) και οι κορυφές για τα ενδιαφερόμενα συστατικά βρίσκονταν στην περιοχή αποτυπώματος 1800-900cm-1. Τα φάσματα των δειγμάτων συγκρίθηκαν μεταξύ τους και βρέθηκαν οι κορυφές απορρόφησης που συνδέονται με τις διαφορετικές συγκεντρώσεις τανινών. Τα αποτελέσματα είναι ενθαρρυντικά για την χρήση της FTIR στην ανάλυση τανινών.

description: We study a chain of non-linear, interacting spins driven by a static and a time-dependent magnetic field. The aim is to identify the conditions for the locally and temporally controlled spin switching. Analytical and full numerical calculations show the possibility of stochastic control if the underlying semi-classical dynamics is chaotic. This is achievable by tuning the external field parameters according to the method described in this paper. We show analytically for a finite spin chain that Arnold diffusion is the underlying mechanism for the present stochastic control. Quantum mechanically we consider the regime where the classical dynamics is regular or chaotic. For the latter we utilize the random matrix theory. The efficiency and the stability of the non-equilibrium quantum spin-states are quantified by the time-dependence of the Bargmann angle related to the geometric phases of the states.

description: Recursive matrix relations for kinematics and dynamics of the Orthoglide parallel robot having three concurrent prismatic actuators are established in this paper. These are arranged according to the Cartesian coordinate system with fixed orientation, which means that the actuating directions are normal to each other. Three identical legs connecting to the moving platform are located on three planes being perpendicular to each other too. Knowing the position and the translation motion of the platform, we develop the inverse kinematics problem and determine the position, velocity and acceleration of each element of the robot. Further, the principle of virtual work is used in the inverse dynamic problem. Some matrix equations offer iterative expressions and graphs for the input forces and the powers of the three actuators.

description: The authors have measured the magnetic response of 33 individual cold mesoscopic gold rings, one ring at a time. The response of some sufficiently small rings has a component that is periodic in the flux through the ring and is attributed to a persistent current. Its period is close to h/e, and its sign and amplitude vary between rings. The amplitude distribution agrees well with predictions for the typical h/e current in diffusive rings. The temperature dependence of the amplitude, measured for four rings, is also consistent with theory. These results disagree with previous measurements of three individual metal rings that showed a much larger periodic response than expected. The use of a scanning SQUID microscope enabled in situ measurements of the sensor background. A paramagnetic linear susceptibility and a poorly understood anomaly around zero field are attributed to defect spins.

description: Humans have a natural ability to effortlessly comprehend linguistic commands such as "park next to the yellow sedan" and instinctively know which region of the road the vehicle should navigate. Extending this ability to autonomous vehicles is the next step towards creating fully autonomous agents that respond and act according to human commands. To this end, we propose the novel task of Referring Navigable Regions (RNR), i.e., grounding regions of interest for navigation based on the linguistic command. RNR is different from Referring Image Segmentation (RIS), which focuses on grounding an object referred to by the natural language expression instead of grounding a navigable region. For example, for a command "park next to the yellow sedan," RIS will aim to segment the referred sedan, and RNR aims to segment the suggested parking region on the road. We introduce a new dataset, Talk2Car-RegSeg, which extends the existing Talk2car dataset with segmentation masks for the regions described by the linguistic commands. A separate test split with concise manoeuvre-oriented commands is provided to assess the practicality of our dataset. We benchmark the proposed dataset using a novel transformer-based architecture. We present extensive ablations and show superior performance over baselines on multiple evaluation metrics. A downstream path planner generating trajectories based on RNR outputs confirms the efficacy of the proposed framework.

description: First-principles methods for time-resolved angular resolved photoelectron spectroscopy play a pivotal role in providing interpretation and microscopic understanding of the complex experimental data and in exploring novel observables or observation conditions that may be achieved in future experiments. Here we describe an efficient, reliable and scalable first-principles method for tr-ARPES based on time-dependent density functional theory including propagation and surface effects usually discarded in the widely used many-body techniques based on computing the non-equilibrium spectral function and discuss its application to a variety of pump-probe conditions. We identify four conditions, depending on the length of the probe relative to the excitation in the materials on the one hand and on the overlap between pump and probe on the other hand. Within this paradigm different examples of observables of time-resolved ARPES are discussed in view of the newly developed and highly accurate time-resolved experimental spectroscopies.

description: The quest to understand better the nature of the initial cosmological singularity is with us since the discovery of the expanding universe. Here, we propose several non-flat models, among them the standard cosmological scenario with a critical cosmological constant, the Einstein-Cartan cosmology, the Milne-McCrea universe with quantum corrections and a non-flat universe with bulk viscosity. Within these models, we probe into the initial singularity by using different techniques. Several nonsingular universes emerge, one of the possibilities being a static non-expanding and stable Einstein universe.

Howickia harrisoni

description: Howickia harrisoni Marshall sp. nov.
(Figs. 25–28)
 Description. Head: Lower half of face bare and shining except for a white pruinose ventral fringe. Upper orbital bristle large, equal to outer vertical bristle; orbital strip otherwise with only minute orbital setulae. Ocelli distinct. Anterior genal bristle enlarged.
Thorax: Postalar, dorsocentral, basal scutellar and apical scutellar bristles subequal. Scutellum microtrichose, 2.0X as wide as long. Wing rudiment short and narrow, similar in dimensions to the halter stem; halter fully developed.
Male abdomen: Sternite 5 slightly longer than sternite 4, slightly paler and concave medially and with posteromedial area flanked by a loose cluster of slightly enlarged bristles; sternite 4 unmodified. Subanal plate complete in upper third only; lower/outer parts of cerci broadly rounded and widely separated. Surstylus deeply bilobed, with a short stout spur at apex of posteroventral lobe, posteroventral lobe narrower and longer than anterior lobe. Distiphallus with a relatively broad but simple tubular distal part overlapped posterodorsally by a narrow lobe of basal part. Postgonite narrow, tapered, gently curved anteriorly and with small setulae on anterior surface. Basiphallus frame-like, projecting posteriorly at right angle to distiphallus base for a distance equal to distiphallus base.
Female abdomen: Hypoproct U-shaped, complete along posterior margin only. Sternite 8 small, setulose on posterior half in a continuous band with the posterior setulosity of the lateral portions of tergite 8.
 Type material. Holotype (male, NZAC, debu00134829) and 4 paratypes (2 males, 2 females, DEBU): North Island, Coromandel Peninsula, 10 km E Thames, pan traps, 22–29.Jan.1999, S.A. Marshall. Other paratypes: North Island, Kauaeranga Valley, Whangaiterenga River, 1.Dec.1970 – 18.Jan.1971, H.A. Oliver (13 males, 2 females, NZAC); Tiki Tiki Stream, Horohoro State Forest, Mamaku Plateau, 24.Jul.1976, J.S. Dugdale, forest litter 76/60 (male, NZAC); Coromandel Peninsula, Kopu Rd., leaf litter, 20 March 1967, R.A. Comber (female, NZAC); Mangakara Stream, Pirongia Mt., meat baited pit traps, 26.Sep.1971, H.A. Oliver (male, female, NZAC).
 Etymology. Howickia harrisoni is named after the great New Zealand dipterist Roy Harrison.
 Comments. This species is easily recognized by its stubby, narrow wing rudiment in combination with the dense white fringe of microtrichia along the lower margin of the mostly bare face. It is clearly defined on the basis of the distinctive surstylus and other male postabdominal features.

description: RESUMO: A crescente preeminência da preocupação ambiental e da busca por respostas aos desafios globais relacionados ao meio ambiente tem se manifestado nas últimas décadas de maneira notória. Este cenário é marcado pela emergência de questões prementes, tais como as mudanças climáticas, a redução da biodiversidade, a degradação dos ecossistemas e a escassez de recursos naturais, cuja importância não pode ser subestimada e deve ser ressaltada dentro da sala de aula, pois ela desempenha um papel fundamental na formação das futuras gerações, promovendo a conscientização , a conexão com o meio ambiente e o desenvolvimento devalores e comportamentos sustentáveis de crianças e jovens. Neste trabalho, foi realizada uma reunião de conteúdos de artigos científicos em bases de dados como Scielo e Google acadêmico. Nesse contexto, este artigo teve o objetivo de apresentar a importância da abordagem do ensino da sustentabilidade para os discentes nas escolas, a forma como se manifesta de maneira a impactar o cotidiano dos estudantes e os desafios do futuro face ao agravamento dos desafios ambientais e à imperiosa urgência de fomentar a sustentabilidade. Esta modalidade educacional assume, portanto, um papel fundamental na configuração da  consciência, valores e condutas das atuais e vindouras gerações, exercendo influência de notório alcance em múltiplos domínios.Palavras-chave: Ambiental, recursos, desenvolvimento, conscientização.

description: Howickia omamari Marshall sp. nov.
(Figs. 7, 8, 39)
 Description. Colour: Face bare and shining at middle only, upper and lower margins white pruinose; gena mostly bare with vibrissal angle and upper margin white pruinose. Legs mostly brown with orange knees, first tarsomere of fore and mid leg reddish brown, other tarsomeres pale brown to white.
Head: Interfrontal bristles in 3 small equal pairs. Upper orbital bristle small, outer vertical similar. Ocelli small but distinct. Aristal hairs 1.5X as long as width of first aristomere.
Thorax: Scutum entirely microtrichose. Postalar and dorsocentral bristles twice as long as scutellar bristles. Scutellum bare and shining except for microtrichose margin, 2.8X as wide as long. Anterior dorsal katepisternal bristle minute or absent, posterior dorsal bristle large. Fore femur swollen, twice as thick as mid femur. Wing present as a short, oval, transluscent flap with a single loop of venation. Portion of wing flap beyond loop of venation subequal to portion enclosed by vein.
 Male abdomen: As described for H. mercurialis, except for the surstylus which is somewhat differently shaped, with a smaller anteroventral lobe, a larger posteroventral spur, and a sinuate ventral surface with a small subquadrate lobe near middle.
Female abdomen: No everted specimens or dissections were available.
 Type material. Holotype female (NZAC): New Zealand, Northland, Omamari Beach Marsh, 27.Jan.1999, S.A. Marshall. Paratypes: Noises Islands, Otata Island, 11–16.Dec.1977, J.C. Watt (1 male, 2 females, NZAC); same location but 16.Dec.1977 – 14.Jan.1978, B.M. May and J.C. Watt, pit trap (3 females, one headless, NZAC); same data but collected 12.Apr.–14.Jun.1978 (1 male, 6 females, one headless, NZAC); same data but collected 25.Oct.1979 (1 female, NZAC); Whangarata, 17.Apr.1981, G. Kuschel, rotten wood (1 male, NZAC); Taupo Bay, pitfall, 21–25.Apr.1985, E. Richardson (1 female, DEBU); Little Barrier Island, Summit Track, 245 m, pit trap, 7–10.Mar.1974, J.C. Watt (1 female, NZAC).
 Etymology. This species is named for the type locality, Omamari Beach Marsh.
 Comments. This is clearly the sister species to H. mercurialis, from the Mercury Islands and the nearby Cuvier Island. Both species have a capsule-like abdomen and similar male genitalia with the exception of the surstylus, which has a unique midventral process in H. omamari. This species is easily distinguished from H. mercurialis by its dull, microtrichose scutum.
