RESUMO

Thorell (1897) erected the monotypic genus Palicanus based on a single male specimen from Yangon (formerly Rangoon) in Myanmar (formerly Burma). Initially the genus was placed in Drassidae Sundevall, 1833, which later became a junior synonym of Gnaphosidae Pocock, 1898. The genus was subsequently transferred to Clubionidae Wagner, 1887 (Simon 1897) and finally to Miturgidae Simon, 1886 (Lehtinen 1967). Palicanus caudatus Thorell, 1897 is notable because of its mouse-grey appearance (Deeleman-Reinhold 2001) and is currently known to occur in China, Indonesia, Myanmar, Reunion Island and Seychelles (World Spider Catalog 2019). Gravely (1931) described Systaria barkudensis (Gravely, 1931), originally placed under Syrisca Simon, 1886, on the basis of specimens collected from the Indian state of Odisha. The species was redescribed once (Majumder Tikader 1991) and later it was transferred to Systaria Simon, 1897 (Deeleman-Reinhold 2001). In this paper, we synonymise S. barkudensis with P. caudatus and provide supplementary information on the somatic morphology and male genitalia with detailed illustrations.

RESUMO

Indian species in the castianeirine genus Castianeira Keyserling, 1879 (Corinnidae) are partly revised based on type materials deposited in the National Zoological Collection, Zoological Survey of India, Kolkata. Two new synonyms are recognized: Castianeira himalayensis Gravely, 1931 syn. nov. is synonymised with Corinnomma severum (Thorell, 1877), and Castianeira bengalensis Biswas, 1984 syn. nov. with the liocranid species Oedignatha scrobiculata Thorell, 1881. Castianeira albopicta Gravely, 1931 is considered as a nomen dubium. Castianeira adhartali Gajbe, 2003 and Castianeira indica Tikader, 1981 are transferred to Oedignatha Thorell, 1881 (Liocranidae). The taxonomic status of both Castianeira tinae Patel Patel, 1973 and Castianeira quadrimaculata Reimoser, 1934 is discussed. All the examined type materials are illustrated, and the current status of the type material of each species is discussed.

RESUMO

The species described as Phonognatha vicitra Sherriffs, 1928 is the only representative of the genus Phonognatha Simon, 1894 in India (World Spider Catalog 2018). The type locality of this species was a coffee estate named Charlotte estate/division, which is located adjacent to the Cauvery River in the Siddapura/ Sidapur village in the Kodagu (Coorg) district of the southwest Indian state of Karnataka (Sherriffs 1928). The species is still known from its original description, which is based on seven female specimens, and its male genitalia remained unveiled. For redescribing this species, we had visited the Charlotte estate/division and collected topotype materials of P. vicitra. However, while examining the materials, we found that the specimens from the Charlotte estate/division indeed belong to the South East Asian orb-weaving spider genus Acusilas Simon, 1895, indicating that Sherriffs misplaced his species in Phonognatha. In the present paper, we propose to transfer P. vicitra to Acusilas and synonymise it with Acusilas coccineus Simon, 1895.

RESUMO

The corinnid species Castianeira zetes was described by Simon in 1897. It has been redescribed several times (Gravely 1931; Tikader 1981; Tikader Biswas 1981; Majumder Tikader 1991; Biswas Raychaudhuri 2000; Sen et al. 2015; Dhali et al. 2017), but none of the above works provided comprehensive somatic as well as genitalic descriptions of the species, and it still remains known only by quite poor drawings. The aim of the present paper is to redescribe and illustrate C. zetes in detail based on the type and new materials.

RESUMO

Zhu et al. (1997) erected the tetragnathid genus Wolongia to accommodate Wolongia guoi Zhu, Kim Song, 1997 and Wolongia wangi Zhu, Kim Song, 1997 collected from the Sichuan and Shaanxi Provinces in China. In 2009, Ping et al. described Wolongia odontodes from the Gaoligong Mountains and remained with a nominal representation after the erection of the genus. This situation was somewhat rectified by Jin-long Wan Xian-jin Peng (2013) reporting seven new species from the Gaoligong Mountains (Yunnan Province, southwest China). The genus currently with ten nominal species; three are known only from females, while seven are from both sexes (World Spider Catalog 2017). During our survey in Pathiramanal Island we found an undescribed Wolongia species. This is one of the most diverse areas of the Kerala state of Southern India, situated in the Vembanad Lake, a Ramsar Convention (2013) site (wetland of international importance). In this paper, we describe this new species and provide the first report of Wolongia from India.

RESUMO

As the species Haploclastus devamatha Prasanth & Jose, 2014 is indistinguishable from Thrigmopoeus psychedelicus Sanap & Mirza, 2014, the latter is herein considered junior synonym of the former. Occurrence of polychromatism in H. devamatha is noted, and two distinct colour morphs of the species are recognised, a pink form and a blue form. The natural history and conservation of the species are discussed and its known distribution is updated.

RESUMO

The dictynid genus Anaxibia Thorell, 1898 currently has six nominal species distributed in the Oriental and Ethiopian regions (World Spider Catalog 2017). The genus represents tiny to small spiders characterised by a reduced cribellum, long, cylindrical anterior and posterior spinnerets, cymbium with caudal modification, palpal patella with dorsal horn, sub-apically arising embolus, conductor with wide lamellar apex and simple female genitalia (Lehtinen 1967). The genus has one representative in India: Anaxibia rebai (Tikader, 1966), originally described under Dictyna Sundevall, 1833 (Tikader 1966; Lehtinen 1967). In this paper, we describe and illustrate a new litter-dwelling Anaxibia species collected from the Kerala state of southern India.

RESUMO

The tetragnathid spider genus Tylorida Simon, 1894 is reviewed in India. The relationship of Tylorida with Orsinome Thorell, 1890 is discussed and illustrated. The taxonomic significance of male chelicerae of Tylorida spp. is discussed and an identification key based on the features of male chelicerae to separate Indian Tylorida spp. is provided. A new species, Tylorida flava sp. nov. is described and illustrated. Two new transfers and four new synonyms are proposed: Orsinome marmorea Pocock, 1901 and Tylorida culta (O. Pickard-Cambridge, 1869) are transferred to Tylorida and Mesida Kulczyn'ski, 1911 respectively, Tylorida cylindrata (Wang, 1991) and Tylorida sataraensis Kulkarni, 2014 are synonymised with Tylorida marmorea (Pocock, 1901) comb. nov., Tylorida nicobarensis (Tikader, 1977) is synonymised with Tylorida striata (Thorell, 1877) and Leucauge pondae Tikader, 1970 is synonymised with Tylorida ventralis (Thorell, 1877). The biology, natural history and intraspecific variations of T. marmorea comb. nov. are noted. The occurrence of intraspecific variations and colour polymorphism in T. ventralis is discussed and two colour morphs (Silver and Yellow morphs) and three varieties (varieties I, II & III) for the species are recognised. Additionally, the genus Atelidea Simon, 1895 is recorded for the first time from India and provided the description and illustration of Atelidea nona sp. nov.. The current distribution of Atelidea is mapped.

RESUMO

The South Asian millipede genus Chondromorpha Silvestri, 1897 is diagnosed and its relationship with Parchondromorpha Jeekel, 1980 is established. The species C. atopus (Chamberlin, 1920) and C. indus (Chamberlin, 1920), as well as the subspecies C. kelaarti kelaarti (Humbert, 1865), C. kelaarti longipes (Verhoeff, 1936) and C. kelaarti valparaiensis (Carl, 1932) are recognised as junior synonyms of C. kelaarti (Humbert, 1865), thereby reducing the total number of Chondromorpha spp. in India to four: C. kaimura Turk, 1947, C. kelaarti, C. mammifera Attems, 1936 and C. severini Silvestri, 1897 (the type-species). Two species, C. kelaarti and C. mammifera, are redescribed and illustrated in detail. All four Indian Chondromorpha spp. are keyed, and the known distribution records of C. kelaarti and C. mammifera are mapped.

RESUMO

The genus Zoica Simon, 1898 comprises the smallest members of the family Lycosidae (Lehtinen & Hippa 1979; Framenau et al. 2009) and all the members are vagrant (Lehtinen & Hippa 1979). The genus was revised by Lehtinen & Hippa (1979) and currently has 12 described species (World Spider Catalog 2017). The species Zoica puellula (Simon, 1898) was based on an unspecified number of female specimens from Sri Lanka, and its original description (Simon 1898) is inadequate and lacks illustrations. The male and female genitalia of this species were subsequently illustrated several times (Roewer 1960; Lehtinen & Hippa 1979; Tikader & Malhotra 1980); however these illustrations are insufficient for proper identification and the internal female genitalia of this species have not been illustrated. Additionally, Tikader and Malhotra (1980) inferred the presence of Z. puellula in India from records of this species in Sri Lanka, but it has not yet been found in India. Here we redescribe Z. puellula based on the type material and newly collected specimens and extend its known geographic distribution to India. We also remove Zoica harduarae (Biswas & Roy, 2008), which was described from India, from the genus.

RESUMO

A new monotypic wolf spider genus, Ovia gen. nov. is proposed to accommodate a misplaced species: Pardosa procurva Yu & Song, 1988. Ovia procurva comb. nov. is redescribed, illustrated and designated as the type species for the genus. The subfamily placement of the new genus is discussed and it is considered as a member of Lycosinae Sundevall, 1833 and possibly closely related to Alopecosa Simon, 1885. The presence of an apical process (spur) on the median apophysis is proposed as the putative synapomorphy of Ovia gen. nov. The possible sister-taxon relationship of Ovia gen. nov. with Alopecosa is discussed and evidence on the occurrence of sexual dimorphism and mating plug within the genus are presented. Ovia gen. nov. is assumed to be of Holarctic origin, from which it has migrated to the Indomalayan region. Additionally, a current distribution map for the genus is provided.

RESUMO

The orb-weaving spider genus Plebs Joseph & Framenau, 2012 currently has only two representatives in India: Plebs himalayaensis (Tikader, 1975) from the Himalayas and Plebs mitratus (Simon, 1895) from the Nilgiris and Anamudi Shola National Park (World Spider Catalog 2016), both are found in high altitude mountainous habitats (Joseph & Framenau 2012). Both species were known only from females (World Spider Catalog 2016), although Sherriffs (1918, 1919) provided a description of an immature male of P. mitratus. In the present paper, we provide the first description of the adult male of P. mitratus, together with the detailed redescription of its female demonstrating considerable intraspecific variation.
