Type material.
Holotype ♀: Myanmar, Kachin State, Putao, Hponkanrazi Wildlife Sanctuary, roadside between Camp 2 to Camp 1; 27°36'067"N, 96°59'367"E; elevation ca 1714 m; 17.XII.2016; Wu J. leg. (IZCAS AR-25158).
Diagnosis.
The new species is similar to I. campanaceus Tong & Li, 2008 in the bell-shaped atrium, but can be distinguished by the short abdominal dorsal scutum (1/3 of the abdomen length (Fig. 1A View Figure 1 ) vs 4/5 of the abdomen length ( Tong and Li 2008: fig. 1B; Tong 2013: fig. 44B), and the greater sinuosity of the winding tube of endogyne (Fig. 1H View Figure 1 ) (vs short, simple winding tube; Tong and Li 2008: fig. 1F; Tong 2013: fig. 44F).
Description.
Female (holotype). Body: habitus as in Fig. 1A-C View Figure 1 ; body length 2.40. Carapace: 1.08 long, 0.98 wide; pale brown, without any pattern, ovoid in dorsal view, slightly elevated in lateral view, surface finely reticulate, fovea absent, lateral margin straight, smooth (Fig. 1D, F View Figure 1 ). Clypeus: height about equal to ALE radius or more (Fig. 1G View Figure 1 ). Eyes: six, in one group, well developed, subequal, ALE circular, PME and PLE oval, posterior eye row procurved from both above and front (Fig. 1D, G View Figure 1 ). Sternum: as long as wide, pale orange, uniform, not fused to carapace, surface smooth, setae sparse (Fig. 1E View Figure 1 ). Mouthparts: chelicerae, endites and labium orange; chelicerae straight, base of fangs unmodified (Fig. 1G View Figure 1 ); labium rectangular, not fused to sternum, anterior margin not indented at middle; endites unmodified (Fig. 1E View Figure 1 ). Abdomen: 1.33 long, 0.74 wide; dorsal scutum well sclerotized, pale brown, covering 1/3 of the abdomen width and approximately 1/3 of the abdomen length, not fused to epigastric scutum; epigastric and postgastric scutum well sclerotized, pale orange, unfused (Fig. 1A, B View Figure 1 ). Legs: pale orange, femur I with two 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 one prolateral spine. Legs III and IV spineless. Epigastric area: surface without external features (Fig. 1H View Figure 1 ). Endogyne: from the middle of the slightly thickened margin of the postgastric scutum runs a dark winding tube posteriorly, ending in a bell-shaped atrium (Fig. 16A, B View Figure 16 ).
