D1101392585B59718AA830EE9DDFBF19.taxon	diagnosis	Diagnosis. The new species is similar to I. taunggyi sp. nov. but can be distinguished by the short abdominal dorsal scutum (very small (Fig. 11 A) vs 3 / 4 of the abdomen length; Fig. 8 A) and ventral scutum (very small (Fig. 11 B) vs 4 / 5 of the abdomen length; Fig. 8 B) of male, and the short abdominal dorsal scutum (very small (Fig. 13 A) vs less than 1 / 2 of the abdomen length; Fig. 10 A) and the inverted bell-shaped atrium (Fig. 17 E) (vs nipple-shaped atrium (Fig. 16 G) of female).	en	Tong, Yanfeng, Li, Shuqiang, Bian, Dongju (2020): Taxonomic study of the genus Ischnothyreus Simon, 1893 from Myanmar (Araneae, Oonopidae).

Clypeus: height about equal to ALE radius or more. Eyes: six, in one group, well developed, subequal, ALE circular, PME and PLE oval, posterior eye row straight from above, procurved from front (Fig. 11 D). Sternum: as long as wide, pale brown, uniform, not fused to carapace, surface smooth, setae sparse (Fig. 11 E). Mouthparts: chelicerae, endites and labium orange; chelicerae straight, base of fangs with crown-shaped sclerotized process with serrated exterior margin (Figs 11 G, H, 15 E, F), fang groove with a few small denticles; labium rectangular, not fused to sternum, anterior margin not indented at middle; anteromedian tip of endites with one strong, tooth-like projection (Fig. 11 E). Abdomen: 1.07 long, 0.72 wide; dorsal scutum weakly sclerotized, pale orange, very small, not fused to epigastric scutum; epigastric and postgastric scutum weakly sclerotized, pale orange, fused, postgastric scutum very small (Fig. 11 A, B). Legs: pale orange, femur I with three prolateral spines, tibia I with four pairs, metatarsus I with two pairs of long ventral spines. Leg II spination is similar to leg I except femur with only two prolateral spines. Legs III and IV spineless. Palp: strongly sclerotized, trochanter with ventral projection, cymbium brown, fused with bulb; bulb brown, with one large ventral protuberance, distal end of bulb elongated, with one narrow leaf-shaped prolateral projection, retrolateral lobe small, simple (Figs 12, 14 G-H).

Carapace: 1.10 long, 0.95 wide; without any pattern, posterior eye row procurved from both above and front (Fig. 13 D, G). Mouthparts: chelicerae and endites unmodified (Fig. 13 E, G). Abdomen: 1.82 long, 1.19 wide. Epigastric area: the postgastric scutum with central anchor-shaped structure (Fig. 13 H). Endogyne: from the middle of the slightly thickened margin of the postgastric scutum runs a dark, simple winding tube posteriorly, ending in a small, inverted bell-shaped atrium (Fig. 17 E, F).	en	Tong, Yanfeng, Li, Shuqiang, Bian, Dongju (2020): Taxonomic study of the genus Ischnothyreus Simon, 1893 from Myanmar (Araneae, Oonopidae).
