description: Genus <i>Sudharmia</i> gen. n. <i>Type species</i>.— <i>Sudharmia pongorum</i> sp. n. The following description concerns species that share many characteristics with Otacilia but in which the genital organs deviate considerably in structure from the species placed in <i>Otacilia.</i> The head is differently shaped. They are separated here into a new genus. <i>Described species</i>.— <i>Sudharmia pongorum</i> sp. <i>n</i>., &amp;male;&amp;female;, Gunung Leuser at Ketambe; <i>S. beroni</i> sp. <i>n</i>., &amp;male;&amp;female;, Island Siberut off the west coast of Sumatra. <i>Unidentified specimen</i> (map 35): Loc. 1: prope <i>Sudharmia</i> cf. <i>beroni,</i> 1 &amp;female;. N Sumatra, Simalungun, 18 km from Prapat, primary forest, 1000 m (MHNG). <i>Diagnosis</i>.— Similar to <i>Otacilia,</i> differs from that genus by the wider and more convex head and the modified genital organs. The chelicerae are differently toothed. The leg tarsi are almost as long as the metatarsi. The male palp has an enormously enlarged and sclerotized embolus. The epigyne exhibits a pair of chitinized ridges in much advanced position immediately lateral to the pedicel which possibly serve as arresting point for the embolus. The vulva is unusually complex and lacks thin-walled bursae, heavily sclerotized and difficult to analyse; the openings are enlarged and sclerotized. <i>Description.</i> — Pale yellow-brown, abdomen without pattern, buff with white pre-anal spot, sometimes a vague pale chevron. Sides of head parallel, sides of thorax convex, carapace seen from side with flat dorsal surface, steeply falling down behind thoracic groove. Thoracic groove well developed. PER wider than AER, occupying 1/2 <i>-</i> 2/3 head width. AE close together, PER recurved, PME small, closer to PLE than to each other; clypeus equal to their d AME. Separate triangular chilum present. Chelicerae with 3 closely set promarginal and 2 tiny, widely spaced teeth on the retromargin. Labium square, as long as wide. Sternum as long as wide with rounded sides, broadly truncate behind, not protruding between coxae IV. Pedicel ventrally with semi-cylindrical ring, not fused with sternum. Retrocoxal window present. Femur I with 1 short dorsal and 1 pl spine distally, anterior tibiae with 5-7, anterior metatarsi with 2 pairs of strong ventral spines; posterior legs spineless, posterior metatarsi with apical brush, tarsal claws toothless. Abdomen with dorsal and epigastric scutum in males, a feeble epigastric scutum only in females. Spinnerets as in <i>Otacilia</i>, distal segment of PLS less prominent. PMS in males larger than in Otacilia, cylindrical-acuminate, in females laterally compressed, with 5-7 mammaeform spigots; PLS in both sexes with several similar spigots. Palpal femur slightly modified, tibial apophysis simple, embolus much enlarged and sclerotized, possibly fused with conductor, tegular apophysis present. Epigyne with complex structure, a pair of chitinized ridges far removed anteriorly near the pedicel; no large bursal sacs visible. <i>Distribution and habitat</i>.— Only found in NW Sumatra, in leaf litter. <i>Etymology</i>.— After its collector Suharto Djojosudharmo.
