Popis: Trilacuna zhigangi Tong & Li sp. nov.Figs 13, 15I, 15J Type material. Holotype ♀: Myanmar, Kachin State, Putao, Hponkanrazi Wildlife Sanctuary; 27°31.592'N, 96°58.266'E; elevation ca 2470 m; 15.V.2017; Wu J. and Chen Z. leg. (IZCAS AR-25157). Diagnosis. The new species is similar to T. bangla Grismado & Ramírez, 2014 but can be distinguished by the short, lateral apodemes (they do not reach the groove connecting the posterior spiracles) and the stick-shaped anterior sclerite of the endogyne (Fig. 15J). Trilacuna bangla has very long lateral apodemes (they distinctly extend beyond the groove connecting the posterior spiracles), and the anterior sclerite has long arms (Grismado et al. 2014: fig. 48A). Description. Female. Body : yellow, chelicerae and sternum lighter, legs yellow; habitus as in Figure 13A-C; body length 2.02. Carapace: 0.86 long, 0.71 wide; sides reticulate; lateral margin rebordered (Fig. 13F). Eyes: ALE largest; PLE and PME nearly equal in size; ALE-PLE separated by less than ALE radius; PME touching each other; posterior eye row recurved as viewed from above, procurved as viewed from front (Fig. 13D, H). Clypeus: height about 1.2 times of ALE diameter. Mouthparts (Figs 13E, H). Sternum (Fig. 13E). Abdomen: 1.20 long, 0.87 wide; booklung covers ovoid, surface smooth; postgastric scutum short, covering about 2/3 abdomen length. Epigastric area (Figs 13G, 15I): surface without external features. Endogyne (Fig. 15J): with narrow, transverse sclerite (tsc), an anterior stick-shaped sclerite (as), and a posterior small globular structure (glo); transverse bars (tba) with two lateral apodemes (ap). Male. Unknown. Etymology. The species is named after Mr Zhigang Chen, one of the collectors of the holotype. Distribution. Known only from the type locality.
