description: Osedax tiburon n. sp.
Figure 4A, B, C
‘nude-palp-A’ (Jones et al. 2008; Rouse et al. 2011; Rouse et al. 2009; Rouse et al. 2015; Vrijenhoek et al. 2009)
Material examined. Holotype: SIO-BIC A7817 female (GenBank COI sequence FJ347622), fixed in formalin preserved in ethanol, collected from whale carcass (Eschrichtius robustus) deployed at 1820 meters depth in Monterey Submarine Canyon, California (36°42.496’N; 122°6.316’W) ROV Tiburon dive number 1163, Dec. 20, 2007. Paratypes: All females, fixed in formalin preserved in ethanol, SIO-BIC A1642 (GenBank COI sequence EU223359), SIO-BIC A7820 (GenBank COI sequence EU223356, EU223357), same locality as holotype, ROV Tiburon dive number 1119, Aug. 16, 2007; SIO-BIC A7818, A7819 (GenBank COI sequences FJ347623, FJ347624, respectively) same locality and date as holotype.
Diagnosis and description. Holotype female (Fig. 4B); preserved trunk 0.75 mm long, 0.2 mm wide; crown of four palps, 3 mm long. Tube gelatinous 6 mm long (Fig. 4A). Oviduct not discerned. In life, palps reddish with blood (Fig. 4A). Four palps without obvious pinnules (Fig. 4B, C). Trunk with no obvious demarcation into upper and lower trunk (Fig. 4B, C). Ovisac mostly missing in holotype, some traces of roots present (Fig. 4A). In paratype ovisac and root complex extends laterally on either side of trunk and posteriorly (Fig. 4C). Males not seen.
Distribution. Known from Monterey Bay, California from 1820 meters depth (Table 2).
Etymology. This species is named (noun in apposition) for the ROV Tiburon, which was used to collect the first Osedax specimens.
Remarks. Osedax tiburon n. sp. is part of Osedax Clade II and is closest relative (though with low support) to Osedax nordenskjoeldi from which it shows a divergence of 15%, though it shows a smaller pairwise distance (14%) to O. ryderi n. sp. (Table 4). The seven available COI sequences for Osedax tiburon n. sp. (Table 3) show less than 1% sequence divergence. It has been found in whale bones and experimentally deployed cow bones. There is little to distinguish Osedax tiburon n. sp. from other 'nude palp' species in Clade II, which share a similar morphology. The species status of Osedax tiburon n. sp. is supported largely on its COI divergence from other Osedax.

Oxytate kanishkai

description: Oxytate kanishkai (Gajbe, 2008)
Dieta kanishkai Gajbe, 2008: 59, figs 1–3 (description and illustrations of female).
Type material. Holotype female from INDIA: Madhya Pradesh: Jabalpur, Tilwaraghat, 02 September 2006, leg. U.A. Gajbe, not examined.
Remarks. O. kanishkai was described based on a single female specimen collected from Jabalpur, Madhya Pradesh, and was neither recollected nor re-described after its original description. We were unable to trace the type specimen in the National Zoological Collection of ZSI, even though the author mentioned that the type would be deposited there. We inquired about the availability of the type at the Zoological Survey of India, Central Zone Regional Centre, Jabalpur, Madhya Pradesh because the author was working there at that time. Unfortunately, we couldn’t find the type specimen from there as well. Therefore, the type material of O. kanishkai is currently considered lost. The female copulatory organ of this species is quite distinct from other Oxytate species reported in India. Although the illustrations are poor, the laterally oriented spermathecae, and the lack of anterior hood cannot be seen in any other Indian congeners (cf. Figs 1C, G–H, 2C–D, G–H, 4 D–F, 5A–E, and 6C–D with figs 2–3 in Gajbe 2008). The available description and the illustrations might help in the identifications of freshly collected specimens from the type locality (Gajbe 2008: figs 1–3). Therefore, we refrain to suggest this name as a nomen dubium.

description: This paper unites the gauge-theoretic and hyperbolic-geometric perspectives on the asymptotic geometry of the character variety of SL(2,C) representations of a surface group. Specifically, we find an asymptotic correspondence between the analytically defined limiting configuration of a sequence of solutions to the SU(2) self-duality equations on a closed Riemann surface constructed by Mazzeo-Swoboda-Weiss-Witt, and the geometric topological shear-bend parameters of equivariant pleated surfaces in hyperbolic three-space due to Bonahon and Thurston. The geometric link comes from the nonabelian Hodge correspondence and a study of high energy degenerations of harmonic maps. Our result has several applications. We prove: (1) the local invariance of the partial compactification of the moduli space of solutions to the self-duality equations by limiting configurations; (2) a refinement of the harmonic maps characterization of the Morgan-Shalen compactification of the character variety; and (3) a comparison between the family of complex projective structures defined by a quadratic differential and the realizations of the corresponding flat connections as Higgs bundles, as well as a determination of the asymptotic shear-bend cocycle of Thurston's pleated surface.

(Figs 7–9)
Material. Holotype right tegmen QM F58591, Dinmore, collected by Robert Knezour. Three paratype tegmina, Dinmore: QM F13625; ACC I.36 +; RKC: QM F58592.
Description. Tegmen c. 18–19 mm long (holotype c. 18 mm), 7.5 mm wide, length/width 2.5, anterior margin convex except at base which is somewhat truncate; stem of R shorter than in M. bryani, its primary fork before clavus ½ length, with 0 or 1 simple costal veinlet; stem of RA with 1 simple costal veinlet; stem of RA1 enters costal margin at about ½ tegmen length, with 2 anterior branches; RA2 with 4–5 branches, sometimes with an endtwig; RP simple or with an up-curved terminal fork; M1 and M3+4 with deep terminal forks; CuA2 much shorter than CuA1; tegmen surface somewhat darkly suffused, noticeably darker in basal costal space, along costal margin, in punctate area of clavus, and along the veins (Fig. 9).
Notes. Eoscartoides dmitryi, from the Dinmore site of the Blackstone Formation, is distinguished from its congeners by its larger size, stronger terminal forking of RP and M, and the shorter CuA2. The specific name honours Dmitry Shcherbakov of the Russian Academy of Sciences. It is only through his ground-breaking work on the classification of fossil Hemiptera that the present study has been possible.

description: Eoscarterella Evans, 1956
Type species. Eoscarterella media Evans, 1956, by original designation.
Diagnostic characters. Tegmen approximately 10 mm long, asymmetrically lobate, apical margin at RA2 gently convex, at M strongly convex, anterior margin fairly straight; precostal carina and marginal membrane very narrow; hypocostal carina well-developed, extending along most of costal space (Figs 11,12); sculpture comprising irregular, short, longitudinally orientated rugae, particularly coarse in basal costal space, grading to a finely punctate sculpture apically (Fig.12); strigil not detected in basal costal space; hyposubcostal carina short, angulately concave; clavus not preserved; primary fork of R proximal to clavus ½ length; primary fork of RA proximal to apex of clavus, at about level of CuA fork; stem of RA1 directed anteriorly, more or less in line with stem of RA, entering costal margin at about ⅔ tegmen length, simple or with 1 or 2 anterior branches; RA2 quite extensive, occupying a large area antero-apically, with 3-5 more or less pectinate branches, the middle one forked; RA2 and RP joined by a crossvein; RP simple, not up-curved apically; M1+2 simple, M3+4 deeply forked; M and CuA joined basally by a weak crossvein; apical m-cu upright; CuA1 strongly concave; CuA2 straight, much shorter than CuA1.
Notes. The retention of a well-developed hypocostal carina is unique among Australian dysmorphoptilids and is considered plesiomorphic for the family (Dmitry Shcherbakov, pers com.). The peculiar tegmen shape and surface sculpture, and the branching pattern of M (M1+2 simple, M3+ 4 forked) are considered as the apomorphies for the genus. It is similar to Eoscartoides, the Australian Permian Belmontocarta Evans (Evans 1958) and the unnamed Triassic species from Kyrgyzstan illustrated by Shcherbakov and Popov (2002, fig.184) in sharing the evenly rounded tegmen without an emargination, the early entry of RA1 into the costal margin rather than the apex and the associated extensive and antero-apically positioned RA2.

Material examined. Holotype: SIO-BIC A1643 palps only (GenBank COI sequence EU235218), fixed in formalin preserved in ethanol, collected from cow bones deployed at 2898 meters depth in Monterey Submarine Canyon, California (36°36.606’N; 122°26.122’W) ROV Tiburon dive number 1069, Oct. 1, 2007.
Diagnosis and description. Holotype represented by fragments of four palps (Fig. 4D), still within a gelatinous tube. Oviduct not discerned. In life, palps reddish with two blood vessels in each, lacking obvious pinnules (Fig. 4D).
Distribution. Known from Monterey Bay, California from 2898 meters depth (Table 2). It has only been found in experimentally deployed cow bones.
Etymology. This species is named (noun in apposition) for the ROV Ventana, which was used to collect many Osedax specimens.
Remarks. Osedax ventana n. sp. is known from only a single partial specimen, sequenced by Jones et al. (2008). It was found on a deployed cow bone and was not discovered during any subsequent sampling at the same site. Osedax ventana n. sp. is part of Osedax Clade II and closest relative (with low support) to Osedax ryderi n.sp., from which it shows an uncorrected divergence of 12% (Table 4). Given the holotype is a fragment, there is little, except for its unique COI sequence, to distinguish Osedax ventana n. sp. from other Clade II species. Three other Osedax species: O. crouchi, O. nordenskjoeldi and O. rogersi, were similarly erected based on fragmented specimens and DNA data (Amon et al. 2014).

description: At present, recognition of the Bangla handwriting compound character has been an essential issue for many years. In recent years there have been application-based researches in machine learning, and deep learning, which is gained interest, and most notably is handwriting recognition because it has a tremendous application such as Bangla OCR. MatrriVasha, the project which can recognize Bangla, handwritten several compound characters. Currently, compound character recognition is an important topic due to its variant application, and helps to create old forms, and information digitization with reliability. But unfortunately, there is a lack of a comprehensive dataset that can categorize all types of Bangla compound characters. MatrriVasha is an attempt to align compound character, and it's challenging because each person has a unique style of writing shapes. After all, MatrriVasha has proposed a dataset that intends to recognize Bangla 120(one hundred twenty) compound characters that consist of 2552(two thousand five hundred fifty-two) isolated handwritten characters written unique writers which were collected from within Bangladesh. This dataset faced problems in terms of the district, age, and gender-based written related research because the samples were collected that includes a verity of the district, age group, and the equal number of males, and females. As of now, our proposed dataset is so far the most extensive dataset for Bangla compound characters. It is intended to frame the acknowledgment technique for handwritten Bangla compound character. In the future, this dataset will be made publicly available to help to widen the research.

Material examined. No new material has been located here. The data below is based on the literature.
Type locality. Florida (Deichmann 1930).
Diagnosis. See Deichmann (1930: 70–71).
Geographical distribution. United States (Florida), Bahamas, Aruba, Curaçao, Colombia, Venezuela and Brazil (Alagoas, Rio de Janeiro) (Hendler et al. 1995, Tommasi 1969, Miranda et al. 2012). According to Hendler et al. (1995) this species occurs up to 4 m deep.
Comments. Two samples (UFAL/ECH 0 610 and UFAL/ECH 0487) are recorded from the reefs of Riacho Doce and Ponta Verde, State of Alagoas (Miranda et al. 2012). According to Hendler et al. (1995), this species is frequently mistaken with H. (S.) surinamensis, due to their similar color, capacity of fission, geographical range and habitats. They differ, however, by the clearly distinct ossicles. Holothuria (Semperothuria) surinamensis does not have buttons and its tables have a reduced disc. Only two species of subgenus Platyperona are known for the Western Atlantic, H. (Platyperona) parvula and Holothuria (Platyperona) rowei Pawson & Gust, 1981. According to Pawson & Gust (1981) the ossicles of both species are of equivalent size, but H. (P.) parvula has buttons with alternate and non-parallel holes, while H. (P.) rowei has thick borders and tables with tapering and a truncate spire. Cutress (1996) noted increases of the tables during somatic growth and described changes in the external morphology and in the shape of the ossicles during growth of the animals.

Prosbolopsites tillyardi Bekker-Migdisova, 1960: 90 (synonymy by Evans 1961).
Material. Holotype right tegmen UQG C1110/1111+, Mount Crosby Locality A. Two additional tegmina, Mount Crosby Locality A: QM F58593 + (listed by Evans (1961) as UQE S8/8A), F58596 + (listed by Evans (1961) as UQE S13/13A and identified as Eoscartoides bryani).
Description. Length 10.3 mm, width 4.5–4.7 mm (holotype 4.7), length/width 2.2-2.3; R without costal veinlets; RA without or with 1 oblique costal veinlet; no colour pattern detected (the darkened costal margin in Fig. 12 is a lighting effect of the merged photographs).
Notes. The crossvein between RA2 and RP could not be detected in the holotype or QM F58593, neither of which are all that clearly preserved, especially in this area of the tegmen. It is, however, present in QM F58596 which although more fragmentary is much better preserved.

description: Genus Pseudoparonella Handschin, 1925
Type species. Paronella appendiculata Schött, 1917.
Type locality. Malanda, North Queensland, Australia.
Diagnosis. Antennae 4-segmented, shorter or subequal to body; chaetae on Ant. I and II much shorter than segmental length. Eyes 8+8, G and H smaller (Fig. 13). Prelabral and labral chaetae 4/5, 5, 4; prelabral ones ciliate. Subapical chaeta of maxillary outer lobe pointed. Labial chaetae MREL1L2, all ciliate. Mesonotum not humped. Dens with two large chaetae at distal tip. Dental spines and scale-like appendage absent. Mucro dorsally fused with dens and with 2‒4 teeth. Tergal chaetotaxy polymacrochaetotic. Scales brown, mostly pointed, coarsely striated, and present at least on Ant. I‒II, head, terga, and ventral side of manubrium and dens; scales on furcula narrower than those on body (Figs 14‒19).
Remarks. The type species of Pseudoparonella was redescribed in detail based on lectotype and paralectotypes by Mitra (1992) and thus not reexamined here. The genus is closest to Plumachaetas in most characters except antennae and subapical chaeta of maxillary outer lobe. The antennae are shorter or subequal to the body in length with antennal chaetae unmodified in Pseudoparonella, but are much longer than body with some chaetae at least 1/2 as long as segment on Ant. I‒II in Plumachaetas. Subapical chaeta of maxillary outer lobe is pointed in the examined species of Pseudoparonella (Table 1). Pseudoparonella also differs from Callyntrura and Dicranocentroides in the smaller mucro weakly separated from dens, 2‒4 teeth in the former, and the mucro usually with at least 5 teeth and sharply separated from dens in the latter two genera.

(Fig. 13)
Non-type material. Strain JD (Vera Cruz, Mexico): 10 males dissected.
Male terminalia. The epandrial ventral processes are divergent (Fig. 13D). The epandrial extensions are located below the surstyli and they present flattened shape at their end (Fig. 13D). Each surstylus has 30 to 35 surstylar teeth, irregularly arranged throughout the internal region, plus 6 thinner primary teeth arranged in a row and a tuft of long surstylar bristles (Fig. 13D). The hypandrium is elongated and thin; the median gonocoxites converge at the end and have hypandrial bristles (Fig. 13A). The aedeagus appears sickle-like (Fig. 13C). The central axis of the aedeagus has a cleft on the dorsal region covered with scales (Fig.13B). The aedeagal apex has a hook shape, with a bipartite and pointed termination (Fig. 13B, C). The aedeagus presents a pair of large and long lateral postgonites (Fig. 13B, C), which are in continuity with the phallapodeme and extend along the entire length of the central axis. The pregonites are fused at the end and have no bristles (Figs. 13C).

description: Since the sixties it is well known that there are no non-trivial closed holomorphic $1$-forms on the moduli space $\mathcal{M}_g$ of smooth projective curves of genus $g>2$. In this paper, we strengthen such result proving that for $g\geq 5$ there are no non-trivial holomorphic $1$-forms. With this aim, we prove an extension result for sections of locally free sheaves $\mathcal{F}$ on a projective variety $X$. More precisely, we give a characterization for the surjectivity of the restriction map $ρ_D:H^0(\mathcal{F})\to H^0(\mathcal{F}|_{D})$ for divisors $D$ in the linear system of a sufficiently large multiple of a big and semiample line bundle $\mathcal{L}$. Then, we apply this to the line bundle $\mathcal{L}$ given by the Hodge class on the Deligne Mumford compactification of $\mathcal{M}_g$.

Holothuria (Holothuria) dakarensis.― Pawson & Shirley, 1977: 915; Prata et al., 2014: 2.
Material examined. Diogo Lopes Beach, Macau, RN, Brazil, 1 spec. (UFPB.ECH-2158).
Type locality. Dakar, Senegal (Panning 1939).
Diagnosis and description. See Prata et al. (2014: 2).
Geographical distribution. United States (North Carolina, Georgia, Gulf of Mexico), Brazil (Rio Grande do Norte), Senegal, Angola (Pawson et al. 2010; Prata et al. 2014), up to 14 m deep.
Comments. This is the only species of the subgenus recorded for the Western Atlantic. Holothuria (Holothuria) dakarensis Panning, 1939 seems to form a species complex with Holothuria (H.) stellati Delle Chiaje, 1824, Holothuria (H.) tubulosa Gmelin, 1791, and Holothuria (H.) mammata Grube, 1840. According to Borrero- Pérez et al. (2009), H. (H.) tubulosa, H. (H.) mammata, and H. (H.) dakarensis may represent valid species after their morphological and molecular analyses, but further studies are necessary to clarify the status of these species.
Ecological note. Buried in sand and algae.

description: Notes on Dichotomius eucranioides Pereira & D’Andretta
Since the time of its description (Pereira & D’Andretta 1955), D. eucranioides has maintained a doubtful position within the subgenus Luederwaldtinia. Pereira & D’Andretta (1955) did not assign this species to a species group but Vulcano et al. (1967) later placed it in the D. assifer species group due the presence of a transversal carina on the head of males. However, we believe that D. eucranioides should be considered to be in its own species group within the subgenus for the following reasons: it is the only species in the genus that has a crenulate clypeal margin (Fig. 2 A); the transversal carina width on the head is subequal to the distance between the eyes and is greater than its height; the pronotal disc of males is anteriorly delimited by four gibbosities; the pronotal declivity of males has two lateral depressions filled with ocellate punctures; and, contrary to the species of D. assifer species group, D. eucranioides hypomeron do not have an anterior excavation delimited medially by a dense brush of red setae. Although D. eucranioides is a brachypterous species, we decided not to redescribe herein since the descriptions of the female (holotype, Pereira & D’Andretta 1955) and of the male (Vulcano et al. 1976) are detailed enough.

‘nude-palp-F’ (Rouse et al. 2015; Vrijenhoek et al. 2009)
Material examined. Holotype: Female, SIO-BIC A1647 (GenBank COI sequence FJ347643), fixed in glutaraldehyde-preserved in ethanol, collected from natural whale fall (Eschrichtius robustus) found at 2898 meters depth in Monterey Submarine Canyon, California (36°36.606’N; 122°26.122’W) ROV Tiburon dive number 1162, Dec. 19, 2007.
Diagnosis and description. Holotype female; in life trunk 1 mm long, 0.5 mm wide (Fig. 7A), crown of four palps, 2.5 cm long (Fig. 7A), likely contracted even at this length. Tube gelatinous, thin, fitting about trunk and base of crown, 4 cm long (Fig. 7A). In life, palps with visible blood vessels and greenish tips (Fig. 7A, inset). Palps without obvious pinnules, oviduct extends slightly beyond palps (Fig. 7A inset). Trunk with pigmented ring demarking upper and lower trunk (Fig. 7B). Ovisac 2 mm by 1 mm with damaged lobate greenish roots extending outwards (Fig. 7B). Males not found.
Distribution. Known from Monterey Bay, California from 2898 meters depth (Table 2). It has only been found in a whale bone fragment, adjacent to the main skeleton.
Etymology. This species is named (noun in the genitive case) for Lonny Lundsten, Senior Research Technician at MBARI, for his enthusiasm and assistance on many Osedax expeditions.
Remarks. Osedax lonnyi n. sp. is part of Osedax Clade II and is the well-supported sistergroup to Osedax rogersi, an Antarctic species with an uncorrected divergence of 12%. Osedax lonnyi n. sp. is remarkable for the very long palps (2.5 cm) that it shows relative to the very short trunk (1.5 mm). The species is known from only a single specimen (holotype) collected in 2007 and no further specimens were found during any subsequent sampling at the same site. This is somewhat surprising as it is one of the larger species of Clade II and the whale fall was sampled a number of times.

Anisophya brasilienesis

description: Anisophya brasilienesis comb. nov. (Brunner von Wattenwyl, 1878)
Isophya brasiliensis Brunner von Wattenwyl, 1878: 61.
Studied specimen: female from Argentina, Córdoba, Cerro La Banderita – La Falda, collected by M. Pocco, 7 March 2010 (photographs available in OSF).
The tiny female is very similar to the female syntype in the Muséum d'Histoire Naturelle in Geneva (which has photographs in OSF), except for better conserved coloration, and perfectly matches Karabag’s diagnosis of Anisophya, as well as Brunner von Wattenwyl’s description of I. brasiliensis. In this description it is not entirely clear if the river “Jugueri grande” is actually a separate locality in Brazil, contrary to being situated in the also mentioned Argentine province Entre Ríos, which is the only specification on the label of the male syntype in Vienna (S. Randolf, pers. comm.). The locality of the female syntype, “Bahia blanca”, is probably Bahía Blanca in the province of Buenos Aires. Giglio- Tos (1894) mentioned also “Buenos Ayres” as locality, without a new collection record. In 1897 he reported the species from San Lorenzo, Provincia de Jujuy in Argentina. So it is uncertain if the species actually occurs in the eponymous country Brazil. Fortunately already in 1906 Kirby designated I. pyrenaea (= Barbitistes pyrenaea Serville, 1838) as type species of Isophya, and not I. brasiliensis, the first of 17 species included by Brunner von Wattenwyl in his new genus, as intended Rehn in 1907.

‘nude-palp-G’, ‘nude palp #20’ (Higgs et al. 2014; Rouse et al. 2015)
Material examined. Holotype: Female, SIO-BIC 4617 (GenBank COI sequence KP119563), fixed in glutaraldehyde-preserved in ethanol, collected from a natural whale fall (Eschrichtius robustus) found at 2898 meters depth in Monterey Submarine Canyon, California (36°36.606’N; 122°26.122’W) ROV Doc Ricketts dive number 234, June 3, 2011. Allotype: Male found in tube of holotype, SIO-BIC A4618.
Diagnosis and description. Holotype female preserved partially dissected from bone; trunk contacted 0.6 mm long, 0.3 mm wide; crown of apinnulate palps contracted, 0.7 mm long (Fig. 8B). Tube not kept for holotype, but forms a tapering sheath in life, from which palps were not seen emerging (Fig. 8A). Oviduct slightly longer than palps visible in holotype (Fig. 8B). In life, palps reddish with two blood vessels each (Fig. 8A). Trunk with no obvious pigmentation or demarcation into upper and lower trunk. Ovisac represented as lobes on either side of trunk in holotype, extending laterally, or as long lobes in other specimens. Roots of holotype longer that the remaining body, extending in several directions as a single lobate mass (Fig. 8B). Male in a tube of holotype a dwarf, 210 µm long by 50 µm wide, with anterior prototroch and sperm squeezed out of head, two posterior expanded segments bearing hooked chaetae (Figs 8C, D). Another possible male, also in tube, resembled newlyrecruited Osedax larva (Fig. 8E).
Distribution. Known from Monterey Bay, California from 2898 meters depth (Table 2). It has been found in whale and turtle bones.
Etymology. This species is named (noun in the genitive case) for Ryder Williams, for his generosity in sharing his mom for our research efforts.
Remarks. Osedax ryderi n. sp. is part of Osedax Clade II and is the well-supported sistergroup to Osedax ventana n. sp., another Monterey Bay species with an uncorrected divergence of 12%. Two other COI sequences obtained for specimens from the type locality, for which no voucher material was obtained, differed from the type specimen by less than 1% (MG262308 from whale bone and MG262309 from turtle bone). There is little to distinguish Osedax ryderi n. sp. from other Clade II species, apart from genetic differences.
