Available Information

Knowledge of Thai semislugs remains scarce, especially the dancing semislug genus Cryptosemelus. Prior to the present study, only a single species has been recognized with little available information. To address this knowledge gap, we surveyed for semislugs in western and southern Thailand, which yielded three species belonging to the genus Cryptosemelus. The little-known type species C. gracilis is redescribed herein, including a comparison with the type specimens. Two additional species, C. betarmonsp. nov. and C. tigrinussp. nov., are described as new to science. All three species are characterized by differences in their genital anatomy, especially with respect to anatomical details of the penis, epiphallus, and spermatophore. In addition, C. tigrinussp. nov. differs from C. gracilis and C. betarmonsp. nov. in the mantle color pattern.

Two New Species

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

The genus Cephaloscyllium Gill 1862 (Chondrichthyes, Carcharhiniformes, Scyliorhinidae) until recently had only two species recognized, C. isabellum [= C. umbratile (Jordan & Fowler 1903)] and C. fasciatum Chan 1966, from the western North Pacific (WNP), with one dubious species, C. formosanum, having been described by Teng in 1962. Recently, three additional species were described, C. circulopullum Yano et al. 2005, C. sarawakensis Yano et al. 2005, and C. parvum Inoue & Nakaya 2006 from this region. Here we present a revision of this genus for the WNP, including redescriptions of C. fasciatum and C. umbratile based on the holotypes, a re-examination of the recently described species, and descriptions of two new species from Taiwan. Cephaloscyllium umbratile can be distinguished from its congeners based on maximum size, length of first dorsal-fin base, anal–caudal space, and dorsal–caudal space. We conclude, based on a comparison of C. parvum and C. sarawakensis, that the former is a junior synonym of the latter species. The two new Taiwanese species can be separated from other WNP species by color pattern, shape of the anterior nasal flap, anal and dorsal-fin size, internarial width, and mouth size. Finally, we present a revised dichotomous key to the WNP Cephaloscyllium recognizing six contemporary taxa: C. circulopullum, C. fasciatum, C. sarawakensis, C. umbratile, C. pardelotum sp. nov. and C. maculatum sp. nov.

Two New Species

The genus Thyridosmylus Krüger (Neuroptera: Osmylidae) belongs to the subfamily Spilosmylinae based on the type species Osmylus langii Mclachlan 1870 (Krüger 1913). The genus has 19 species mainly distributed in Asia, especially in China where there are 14 species: Thyridosmylus polyacanthus sp. nov., Thyridosmylus trimaculatus sp. nov., Thyridosmylus minoroides Yang, 1987, Thyridosmylus laetus Yang, 1988, Thyridosmylus pulchrus Yang, 1988, Thyridosmylus medoganus Yang, 1988, Thyridosmylus similaminor Yang, 1992, Thyridosmylus trifasciatus Yang, 1993, Thyridosmylus triypsiloneurus Yang, 1995, Thyridosmylus maolanus Yang, 1993, Thyridosmylus qianus Yang, 1993, Thyridosmylus fuscus Yang, 1999, Thyridosmylus vulgatus Yang, 1999 and Thyridomsylus pallidius Yang, 2002. Three species are described from India (Thyridosmylus langii (McLachlan 1870), Thyridosmylus perspicillaris (Gerstaecker, 1885), Thyridosmylus pustulatus Kimmis 1942) while another two species are known from Madagascar (Thyridosmylus marmoratus Fraser, 1955 and Thyridosmylus punctulatus (Navás, 1933)). Gerstaecker (1885) described one subspecies Thyridosmylus perspicillaris perspicillaris Gerstaecker and Kimmins (1942) erected three additional subspecies, Thyridosmylus langii angustus Kimmins, 1942, Thyridosmylus perspicillaris fenestratus Kimmins, 1942, Thyridosmylus perspicillaris minor Kimmins, 1942. However due to rampant variation in colouration and venation, the valid status of these subspecies is doubted and they are provisionally treated as synonyms herein. Thyridosmylus is characterised by fuscous and maculate forewings and largely hyaline hind wings, moderately sized and usually ochreous body, costal cross-veins simple and radial field with numerous cross veins (not including gradates). In the male genitalia, the anal plate generally elevates into a fingerlike process on the dorsal margin, and parameres are commonly arcuate in lateral view. Female genitalia usually have a broad anal plate, while the gonapophysis lateralis is finger-like or coniform in lateral view. In this paper, two new species are described from China. Terminology follows Tjeder (1957) and New (1986). All the type specimens are deposited in the Entomological Museum of China Agricultural University (CAU), Beijing.

The species of Hemibrycon occurring in the east of the Andean Cordilleras are reviewed based on their type series and additional specimens. Nine species are redescribed: H. beni from río Beni basin, Bolivia; H. helleri from the upper rio Ucayali, Peru; H. huambonicus from the ríos Huallaga and Marañon basins, Peru; H. jeslkii from the upper portions of ríos Marañon, Ucayali and Madeira basins, Bolivia, Brazil, and Peru; H. metae from río Orinoco basin, Colombia and Venezuela, and Caribbean coastal basins of Venezuela; H. polyodon (type species) from río Pastaza basin, Ecuador; H. surinamensis from coastal basins of French Guiana and Suriname, and from lower rios Tapajós, Tocantins and Xingu basins, Brazil; H. taeniurus from river basins from Trinidad Island, Trinidad and Tobago, and H. tridens from upper río Ucayali basin, Peru. Two new species are described: H. inambari from the upper río Madre de Dios basin, Peru and H. mikrostiktos from río Ucayali basin, Peru. These species are distinguished among themselves mainly by the color pattern, and meristic characters. The distribution area of the genus is enlarged reaching the lower Tapajós, Tocantins and Xingu river basins, Brazil, with the first record of the occurrence of H. surinamensis in this country. A new description and diagnosis is provided for the type species of the genus, regardless its recent redescription. The type series of H. helleri that was previously considered dubious is found and described. Hemibrycon coxeyi and H. pautensis are considered junior synonyms of H. polyodon. Tetragonopterus (Hemibrycon) trinitatis, previously considered species inquirenda in Characidae, and Hemibrycon guppyi are junior synonyms of H. taeniurus. Hemibrycon orcesi is transferred to Boehlkea. A taxonomic key for the species of the genus to the east of the Andean Cordilleras is presented.

The Oriental and Australasian species of Acmopolynema Ogloblin (Mymaridae) are reviewed; a key to 19 species with known females is given. The genus Baburia Hedquist is synonymized under Acmopolynema and its type species is transferred to Acmopolynema as A. narendrani (Hedquist) comb. n. Ten new species of Acmopolynema are described: A. capeyorki sp. n. (Australia), A. dilemma sp. n. (China), A. garemma sp. n. (Indonesia), A. isaura sp. n. (Indonesia), A. lurindu sp. n. (Nepal), A. neznakomka sp. n. (Papua New Guinea), A. nupta sp. n. (Nepal), A. orchidea sp. n. (Taiwan), A. problema sp. n. (India), and A. shinbana sp. n. (Malaysia). The following new synonymies are proposed: A. maculata Subba Rao and A. nixoni Subba Rao under A. orientale (Narayanan, Subba Rao & Kaur), A. reticoxilla Xu & Lin under A. longicoxillum Xu & Lin, A. himalum Hayat & Anis under A. indochinense (Soyka), and Baburia fasciata Hedquist under A. tachikawai Taguchi. The genera Chaetomymar Ogloblin and Acanthomymar Subba Rao are synonymized under Palaeoneura Waterhouse, which is redescribed along with its type species, P. interrupta Waterhouse (Australia). Ten species of Chaetomymar, 32 Australian species described originally in Polynema Haliday, Polynema nigrum (Subba Rao) (type species of Acanthomymar), and Acmopolynema unimaculatum Hayat & Anis are transferred to Palaeoneura as new combinations. Polynema ara Girault (= P. blackbourni Girault, syn. n. and P. helena Girault, syn. n.) is transferred to Richteria Girault; P. elatum Girault, P. glabricorpus Girault, P. grotiusi Girault, P. lodgei Girault and P. wallacei Girault are transferred to Agalmopolynema Ogloblin, all comb. n. from Polynema. One new genus and one new subgenus are described: Boccacciomymar gen. n., with type species Palaeoneura turneri Waterhouse (Australia) and Prosto, subgen. n. of Boccacciomymar, with type species Polynema victoria Girault (Australia). Polynema schumanni Girault and P. quadripetiolatum Girault are synonymized under Boccacciomymar (B.) turneri (Waterhouse), comb. n. from Palaeoneura. Palaeoneura evanescens Waterhouse is transferred to Boccacciomymar as B. (B.) evanescens (Waterhouse), comb. n.; Polynema aligherini Girault and P. victoria are transferred to Boccacciomymar (Prosto) as, respectively, B. (P.) aligherini (Girault), comb. n. and B. (P.) victoria (Girault), comb. n. Two new species of Boccacciomymar (Boccacciomymar) and four new species of B. (Prosto) are described: B. (B.) conquistador sp. n. (Australia), B. (B.) decameron sp. n. (Australia), B. (P.) maria sp. n. (Australia), B. (P.) nigugu sp. n. (Australia), B. (P.) pobeda sp. n. (New Zealand), and B. (P.) tak sp. n. (New Zealand). A key to the Australian Polynema-group genera of Mymaridae is provided. The Neotropical genus Xenopolynema Ogloblin, stat. rev., with type species X. areolatum Ogloblin stat. rev., is removed from previous synonymy under Polynema, reinstated as a valid genus, and re-diagnosed based on the type specimens from Argentina and new material from Chile; its relationships with Boccacciomymar are discussed.

The genus Areopaguristes Rahayu & McLaughlin, 2010 is represented in the eastern Pacific by a single species, A.mclaughlinae (Ayón-Parente & Hendrickx, 2006). Based on material recently collected in the Gulf of California, Mexico,and held in museum collections, two new species of this genus are described. Areopaguristes lemaitrei sp. nov. and A.waldoschmitti sp. nov. Both have the typical 12 gills of the genus. In addition to its color pattern, A. lemaitrei sp. nov. isdistinguished by the presence of corneous-tipped spines on palm and fingers, a broadly rounded rostrum shorter than lat-eral projections, and by the shape of the external lobe of the first pleopod. Areopaguristes waldoschmitti sp. nov. also fea-tures a distinctive color pattern, a less spinous armature of chelipeds, antennular peduncles proporcionally longer andantennal acicle shorter, a deep median cleft on the posterior margin of telson, and the distal margin of the inferior lamella of the first male pleopod is unarmed; this last character separates A. waldoschmtti sp. nov. from all its congeners.

Four new genera including five new species are described. All are from north-eastern Queensland. Barbaragraecia comprises two new species. B. unicorn Rentz & Su, gen. et sp. nov. (the type species) and B. richardsoni Rentz & Su, sp. nov. Geoffagraecia is known from a single species, G. gwinganna Rentz & Su, sp. nov. the type species. Greenagraecia Rentz & Su, gen. et sp. nov. is known from two species, G. attenuata Rentz & Su, gen. et sp. nov., the type species and G. cooloola Rentz & Su, gen. et sp. nov.. The unrelated genus Nicsara Walker 1869 is discussed and species with falcate ovipositors are removed and placed in a new genus, Larifugagraecia Rentz & Su gen. nov., with Nicsara spuria Redtenbacher 1891 designated as the type species. Two species are removed from Nicsara and placed in Larifugagraecia. These are N. cornuta (Redtenbacher 1891) and N. spuria. Other species remain in Nicsara until they can be further assessed. Biological and ecological notes accompany detailed descriptions of the new species along with many morphological illustrations. Illustrations also are provided for L. spuria gen. nov. A key to the described fully-winged Australian agraeciine genera is provided at the end of the paper.
