A total of 108 species of spider species belonging to 84 genera and 25 families were identified from the scrub jungle of the Madras Christian College campus.  Pagida salticiformis (O. Pickard-Cambridge, 1883) is recorded for the first time from India.  Langona tigrina (Simon, 1885) is rediscovered 135 years since its first description and the unknown male is described and illustrated.  A new combination, Langona davidi (Caleb, Mungkung & Mathai, 2015) comb. nov. is proposed for the species previously placed in Phlegra.  Three new synonymys have been recognized: Clubiona foliata Keswani & Vankhede, 2014 and Clubiona pashabhaii Patel & Patel, 1973 are junior synonyms of Clubiona filicata O. Pickard-Cambridge, 1874 and Myrmarachne megachelae Kumar & Mohanasundaram, 1998 is a junior synonym of Myrmaplata plataleoides (O. Pickard-Cambridge, 1869).  Distribution records of several species have been updated and as many as 31 species are recorded for the first time from Tamil Nadu State.  The family Salticidae is the most diverse with 28 species belonging to 22 genera followed by Araneidae with 19 species in 11 genera.  Guild structure analysis revealed seven feeding guilds of which, stalkers and orb-web weavers are the dominant feeding guilds followed by ground runners, ambushers, and scattered line weavers, respectively.

Subjective Synonym

The genus Surenus Distant, 1901 (Hemiptera: Heteroptera: Pentatomoidea: Pentatomidae: Pentatominae: Halyini) is revisited and found to be a junior subjective synonym of the genus Agathocles Stål, 1876 (currently Pentatominae: Rolstoniellini). The genus Agathocles and its type species, Agathocles limbatus Stål, 1876, are redescribed. Lectotype of Surenus normalis Distant, 1901 (= Agathocles normalis (Distant, 1901) comb. nov.) is designated and the unknown male of the species is described. Agathocles yunnanensis Zhang & Lin, 1984, syn. nov., is considered junior subjective synonym of A. limbatus. Two new species are described: Agathocles flavipes sp. nov. from India (Andhra Pradesh, Karnataka, Maharashtra, and Tamil Nadu) and A. joceliae sp. nov. from Malaysia (Kelantan, Perak). The new species differ from their congeners mainly by the morphology of mandibular plates, length of antennomeres I, IIa and IIb, body length, and structure of male genitalia. Agathocles dubius Distant, 1921 is transferred to the genus Caystrus Stål, 1861 (Pentatominae: Caystrini) based on examination of its holotype with the resulting new combination: Caystrus dubius (Distant, 1921), comb. nov. One new combination is proposed, Paramecocoris ruficornis (Fieber, 1851), comb. nov. (from preoccupied Paramecus Fieber, 1851), and its type locality is clarified as Tenasserim (south Myanmar). Gender agreement and authorship of the name Riazocoris niger Ahmad & Afzal, 1977 in Ahmad et al. (1977: 161) are corrected and status of its name bearing type is clarified as lectotype. The following new distribution records are given: A. limbatus from Cambodia, China (Guangxi, Tibet), Laos and Thailand, A. normalis, Caystrus obscurus (Distant, 1901a) and Critheus lineatifrons Stål, 1869 from Laos, Amasenus corticalis Stål, 1863 from Cambodia, Indonesia (E Kalimantan), Laos, Myanmar and Thailand, and Rolstoniellus boutanicus (Dallas, 1849) from Vietnam. Based on characters of external morphology and genitalia, the genus Agathocles is compared with representatives of the genera Halys Fabricius, 1803 (Halyini), Caystrus (Caystrini), Laprius Stål, 1861 (Myrocheini), and Exithemus Distant, 1902 (currently in Rolstoniellini). As a result, the genus Agathocles is here transferred to the tribe Caystrini. The genus Kyrtalus Van Duzee, 1929 is tentatively placed in Myrocheini based on the presence of sulcate mesosternum and femora provided with teeth.

Generic concepts in the Testudinaceae (Ascomycotina, Loculoascomycetes) are reviewed with particular emphasis on the sculpturing of the ascospores which has been examined by scanning electron microscopy (SEM) for the first time. A key to the nine genera accepted in the family is provided of which two are described as new: Ulospora for U. bilgramii comb.nov. (= Zopfia bilgramii D. Hawksw. et al.), the ascospores of which have three to six deep fissures in each cell, and Zopfiofoveola for Z. punctata comb.nov. (= Zopfia punctata D. Hawksw. & C. Booth), with distinctly and regularly foveolate ascospores. One further new combination is made: Rechingeriella boudieri comb.nov. (= Zopfia boudieri Arnaud). The positions of three additional genera referred to the family by earlier authors but which are excluded from it here are also briefly discussed.

A new genus of lichenized fungi of the family Porinaceae is described, known from Costa Rica and Brazil. Flabelloporina Sobreira, M. Cáceres & Lücking is a thus far monospecific genus with an isolated position of its only species in the family, morphologically different from all other genera in Porinaceae. The genus is characterized by the production of numerous, flabelliform squamules on the surface of the thallus, together with black perithecia and transversally septate ascospores (with three septa in the only species). The new combination Flabelloporina squamulifera (Breuss, Lücking & Navarro) Sobreira, M. Cáceres & Lücking is proposed, based on Porina squamulifera Breuss, Lücking & Navarro, and the species is for the first time reported from Brazil.

Chandrasekhara Venkata Raman was born at Trichinopoly in South India on the 7 November 1888. Raman’s parents, Chandrasekhara Iyer and Parvati Ammal, lived at that time in what was then called the province of Madras, a part of India now known as the Tamil Nadu. The family, for many generations, had been pursuing the profession of agriculture and were of moderate means. Family traditions in those days were such that if anyone attempted to break off from them, it would have been regarded as a bold step. Raman’s father did take such a bold step when for the first time in the family, he took to teaching in the local English High School. This bold step was followed by another when Mr Chandrasekhara Iyer decided to accept the post of lecturer in physics and mathematics at the Mrs A. V. N. College, Vizagapatam; Raman was then four years old. Vizagapatam, now known as Visakhapatnam, is a sea-port town on the east coast of India and situated in the State of Andhra Pradesh. Thus, the parents and with them the four-year-old son moved to Vizagapatam. The next ten years of Raman’s life were spent at Vizagapatam, where he studied for eight years in the High School and two years in the College. He passed the Intermediate examination in 1902, enabling himself to join for a university degree course. In January 1903, he moved to Madras and joined the Presidency College. He passed his B.A. degree examination in 1904, winning the first place and a Gold Medal in physics. He passed the M.A. degree examination in 1907, again obtaining a first division and record marks.

The genus Hersilia was established by Audouin in 1826 with H. caudata Audouin, 1826 as the type species. It is the most speciose hersiliid genus presently comprising 79 described species worldwide (World Spider Catalog 2017, version 18). There are seven species known from India: H. aadi Pravalikha, Srinivasulu & Srinivasulu, 2014, H. longivulva Sen et al., 2010, H. orvakalensis Javed et al., 2010, H. savignyi Lucas, 1836, H. striata Wang & Yin, 1985, H. sumatrana (Thorell, 1890), H. tibialis Baehr & Baehr, 1993. This paper is based on fresh material collected from the patches of scrub jungle enclosed within the Madras Christian College campus, Chennai, Tamil Nadu, India. Both sexes of H. savignyi are illustrated. H. aadi Pravalikha, Srinivasulu & Srinivasulu, 2014 is synonymized with H. savignyi Lucas, 1836.

The genus Martensopoda gen. nov. is established for two species from South India with distinct and apomorphic features in their copulatory organs. A cymbial spur in the male copulatory organs is reported the first time in the Sparassidae. The embolus’ loop — unique to Heteropodinae — is oriented transversally to the plane of the alveolus. Females exhibit spirally coiled copulatory openings similar to those of Spariolenus, but with a posterior pit at the median septum and with lateral loops of the internal duct system. Martensopoda transversa sp. nov. is described from Cardamon Hills in Kerala State (male, female), Martensopoda minuscula (Reimoser 1934) comb. nov. is known only from females and is recorded from Palni Hills, Tamil Nadu State.

New taxonomic data on the ground spiders of the family Gnaphosidae from Greece are presented. Two genera are proposed as new to science (Marjanus gen. n. and Lasophorus gen. n.) together with two new species (Lasophorus zakkak sp. n. and Lasophorus zografae sp. n.) and a new combination (Marjanus platnicki comb. nov.). Additionally the genus Turkozelotes Kovblyuk & Seyyar, 2009 is here rediagnosed and the female of the type species T. microb Kovblyuk & Seyyar, 2009 is described for the first time. The finding of the matching male of Setaphis mccowani Chatzaki & Russell-Smith, 2017 suggests the transfer of this species to Turkozelotes and hence the male of T. mccowani comb. nov. is described for the first time. Taxonomic affinities of these genera and species are discussed.

A New Species

Ninety percent of the Cixiidae of the Macaronesian archipelagos are endemic. Each archipelago has its own endemics reaching a total of 31 taxa. The Madeira archipelago comprises five species: Cixius madeirensis China, 1938, C. verticalis Noualhier, 1897, C. chaoensis China, 1938, Hyalesthes madeires Remane & Hoch, 1986 and H. portonoves Remane & Hoch, 1986. Good knowledge concerning taxonomy, habitat information and distribution are essential for the conservation of the biodiversity of this rich archipelago. However, due to intraspecific variation and incomplete descriptions, misidentifications of Madeira cixiids have been common. In this work, the taxonomy of this family is reviewed and ecological data based on material collected over more than forty years are presented. A new species, Cixius wollastoni sp. nov., is described. A new combination, Tachycixius chaoensis (China, 1938) comb. nov., is proposed, and a new record, Pentastiridius leporinus (Linnaeus, 1761), is reported. Lectotypes are designated for Tachycixius chaoensis and C. verticalis. The genital structures of the latter species are depicted for the first time. All species are diagnosed, described, photographed and illustrated, and an identification key for the family is provided. Thanks to this new information, Madeira together with Tenerife are the two Macaronesian islands with the highest number of endemic species of cixids.
