Ischnothyreus putao Tong & Li sp. nov. Figures 6 View Figure 6 , 17C, D View Figure 17
Type material.
Holotype ♀: Myanmar, Kachin State, Putao, Hponkanrazi Wildlife Sanctuary, roadside between Camp 1 to Camp 2; 27°36'567"N, 96°.58'850"E; elevation ca 2233 m; 15.XII.2016; Wu J. leg. (IZCAS AR-25175).
Diagnosis.
The new species is similar to I. zhigangi sp. nov. in the very small abdominal dorsal scutum and the brown carapace, but can be distinguished by the large bell-shaped atrium (Fig. 17C View Figure 17 ) (vs small, bell-shaped atrium; Fig. 17E View Figure 17 ), and the smoothly curved posterior margin of postgastric scutum (Fig. 6H View Figure 6 ) (vs straight posterior margin; Fig. 13H View Figure 13 ).
Description.
Female (holotype). Body: habitus as in Fig. 6A-C View Figure 6 ; body length 1.94. Carapace: 0.97 long, 0.88 wide; dark brown, without any pattern, ovoid in dorsal view, strongly elevated in lateral view, surface finely reticulate, fovea absent, lateral margin straight, smooth (Fig. 6D, F View Figure 6 ). Clypeus: height about equal to ALE radius or more (Fig. 6G View Figure 6 ). Eyes: six, in one group, well developed, subequal, ALE circular, PME and PLE oval, posterior eye row procurved from both above and front (Fig. 6D, G View Figure 6 ). Sternum: as long as wide, pale brown, uniform, not fused to carapace, surface smooth, setae sparse (Fig. 6E View Figure 6 ). Mouthparts: chelicerae, endites and labium brown; chelicerae straight, base of fangs unmodified (Fig. 6G View Figure 6 ); labium rectangular, not fused to sternum, anterior margin not indented at middle; endites unmodified (Fig. 6E View Figure 6 ). Abdomen: 1.30 long, 0.89 wide; dorsal scutum weakly sclerotized, very small, not fused to epigastric scutum; epigastric and postgastric scutum well sclerotized, pale orange, unfused (Fig. 6A, B View Figure 6 ). 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 spine. Legs III and IV spineless. Epigastric area: the postgastric scutum with central, anchor-shaped structure, and smoothly curved posterior margin (Fig. 6H View Figure 6 ). Endogyne: from the middle of the slightly thickened margin of the postgastric scutum runs a dark, simple winding tube posteriorly, ending in a large, inverted bell-shaped atrium (Fig. 17C, D View Figure 17 ).
