Holotype male ( SMF), MYANMAR   , southern Chin State, above Kampetlet, below Mountain Oasis Resort , 21°11’43.6”N 94°02’1.1”E, 1585 m a.s.l., secondary forest along stream, by hand & sifting, at day; 17.V.2014; P. Jäger leg. GoogleMaps  

Etymology. The specific name is a noun in apposition referring to the terra typica of the new species.

Diagnosis. The new species is diagnosed by the poorly modified carapace, i.e. absence of high elevation(s) or specific structures, by the spoon-shaped distal suprategular apophysis, and small, S-curved embolus. The poorly modified carapace and the conformation of the male palp somewhat resemble those in O. kodaikanal Tanasevitch, 2015   , from the highlands of Tamil Nadu, India ( Tanasevitch 2015). The new species is distinguished from O. kodaikanal   by a much larger convector that clearly protrudes forward.

Description. Male holotype. Rather large Erigoninae   , total length 2.13. Carapace 0.90 long, 0.70 wide, slightly modified: head part slightly elevated and bearing short spines ( Fig. 6 View FIGURES 1 – 7 ); pale brown, with indistinct, grey, radial stripes. Chelicerae unmodified, 0.45 long. Legs yellow. Leg I, 3.00 long (0.80+0.25+0.75+0.70+0.50), IV, 3.20 long (0.85+0.25+0.80+0.85+0.45). Chaetotaxy 2.2.1.1, length of spines about 1–1.5 diameters of segment. Each metatarsus with a trichobothrium. TmI, 0.50. Palp ( Figs 43–47 View FIGURES 43 – 47 ): Tibia elongated, with a very small denticle apically and a wide, rounded, darkened outgrowth retrolaterally. Paracymbium L-shaped, bearing several strong spines on distal lobe. Distal suprategular apophysis with a rounded hollow, spoon-shaped. Distal apophysis of convector well protruded forward. Embolus relatively short, thick, S-curved. Abdomen ( Fig. 7 View FIGURES 1 – 7 ): 1.13 long, 0.75 wide, dorsally pale, with three pairs of large, grey, paramedian spots.

Female. Unknown.

Distribution. Only known from the type locality in Myanmar   .
