Teutamus Thorell

Genus Teutamus Thorell (plate 7) Teutamus Thorell, 1890: 281. Type species Teutamus politus Thorell, 1890, ♀, Malaysia, Penang. Described species. — The type species T. politus Thorell, ♀, Penang; T.fertilis sp. n., ♂♀, N Sumatra, this volume; T. jambiensis sp. n., ♂♀, W Sumatra, this volume, T. rhino sp. n., ♂♀, W Java, this volume; T. rothorum sp. n., ♂♀, W Java, this volume; T. andrewdavisi sp. n., ♂♀, N Borneo, this volume; T. vittatus sp. n., ♂♀, N Borneo, this volume. The new species are described in geographic order. Unidentified specimens (map 40): Loc. 1: prope fertilis I, Malaysia, Perak, Padang Gerus, 1 ♂, S of Ipoh, P. Schwendinger (MHNG); 2 ♂, 1 ♀, Chenderiang, primary evergreen forest, P. Schwendinger (MHNG); Perak, Taiping, 2 ♂ 1 ♀, Maxwell Hill (= Bukit Larut), montane rain forest, P. Schwendinger (MHNG); Thailand, Satun province, 3 ♂, 4 ♀. Thale Ban National Park, 6°, 42' N, 100°,10'E, lowland rain forest, IV>II>III. Legs thin, in particular metatarsi and tarsi, the latter widening towards tip; claw tufts lacking. First pair of femora with 1 or more prolateral distal spines, other femora spineless, anterior tibiae and metatarsi ventrally flattened, with a double row of very long strong tuberculate spines; posterior tibiae and metatarsi spineless; tarsal trichobothria as in fig. 811, tarsal claws with 3 teeth, claws of leg IV strongly arched. Pedicel fused with sternum. Abdomen in males widening towards the tip, the tip abruptly truncate, in females and some males abdomen oval. Ventral epigastric scutum produced anteriorly into a ribbed collar, males with dorsal and ventral scuta fused into chitinous sheath over 3/4 - 5/6 of abdomen (fig. 807), females ventrally with epigastric ventral scutum, which surrounds the entire anterior part of the abdomen; dorsal and postgenital scutum absent in females. In males of T. politus and T. fertilis, ventral postgenital scutum receding diagonally fig. 796, 797. In females, PM spinnerets strongly compressed laterally, packed with rows of spigots (figs 812-814), PLS with very small distal segment, provided with few similar spigots. Male palpal tibia with two blunt apophyses with clawlike tip. Tegulum simple, swollen, with wide dark sperm duct, the latter leading most often towards a filiform coiled embolus on dorsal, in normal position invisible side of bulb (see fig. 829); embolus in a clockwise coil in left palp on apical and distal-dorsal surface of tegulum, tip of embolus aligning apical claw-like or conical conductor, sometimes there is a second projection on the tegulum. Vulva with a pair of large spermathecae posteriorly and short ducts, lateral to the spermathecae a pair of chitinized cones on the interior side of the tegument (’’apodemes”); openings anterior, unpaired and asymmetric in T. politus. Opening often plugged with a black substance. Bursae very small. Autospasy: legs break off rarely; if so, then at the coxa-trochanter joint. Distribution. — Malay Peninsula, Borneo, Sumatra, W Java. Habitat. — Spider of dark humid rainforests, primary and undisturbed secondary. Collected by sifting leaf litter; often seen wandering about by daytime on the forest floor. The species were found to have small ranges: most species were found in one locality only. Exceptionally, T. politus, which is the northernmost species known at present was also found at a distance of 350 km from the type locality in southern Thailand. At any place there was never more than one species.Published as part of Deeleman-Reinhold, Christa, 2001, Forest Spiders of South East Asia With a revision of the sac and ground spiders (Araneae: Clubionidae, Corinnidae, Liocranidae, Gnaphosidae, Prodidomidae and Trochanteriidae)., pp. 400-505 in Forest Spiders of South East Asia With a revision of the sac and ground spiders- Family Liocranidae, Leiden, Netherlands :Brill Leiden; Boston; Köln on pages 470-472, DOI: 10.5281/zenodo.81470
