Type material.

Holotype: ♂ ( IZCAS Ar-25095), Myanmar, Kachin State, Putao, Mahmolae Village, 21°23.211'N, 97°21.485'E, 415 m, Wu J. & Chen Z., 5.V.2017. Paratypes: 1♂, 2♀ ( IZCAS Ar-25096), same data as holotype; 1♂ ( IZCAS Ar-25097), Myanmar, Kachin State, Putao, roadside between Nahteukhu and BaAve, 27°18.000'N, 97°23.267'E, 535 m, Wu J., 8.X.2016.


The species epithet, a noun in apposition, refers to the type locality.


The new species is similar to K. putao  sp. n. but can be distinguished by the proportion of the cymbiobulbus (length/maximal width = 2.6) (Figure 4I), the collapsed lobe of the embolus complex (clo, Figure 5B, D) and the long, strong setae on the abdominal scutum (sls, Figure 4E, G) in males, and the presence of a triangular plate (pl, Figure 6G, I) of the endogyne.


Male (holotype). Habitus as in Figure 4A, C, E. Body length 1.76; carapace 0.87 long, 0.72 wide; abdomen 0.78 long, 0.56 wide.

Palp (Figure 4 I–K): Femur 0.28 long, 0.14 width, length/maximal width = 2. Cymbiobulbus 0.42 long, 0.16 wide, length/maximal width = 2.6. Embolus complex (Figure 5B, D, F) with four projections from prolateral view, including a collapsed, strongly curved lobe (clo), a leaf-like projection (llp), a broom-like projection (blp), and a long, brush-like projection (bpr); with a large, ear-shaped lobe (lel) in retrolateral view, the distal end with filiform lobe (fil).

Female. Habitus as in Figure 6A, C, E. Body length 1.72; carapace 0.75 long, 0.64 wide; abdomen 0.91 long, 0.67 wide. Postgastric scutum 0.34 long, 0.45 width, length/width ratio = 0.75.

Genitalia. Ventral view (Figure 6G, I): middle part of anterior margin of postgastric scutum strongly sclerotized (asr), with a triangular plate (pl). Dorsal view (Figure 6J): with a T-shaped sclerite (tsc) anteriorly, followed posteriorly by a tube-like posterior receptacle (pr) (Figure 6I); from lateral view, the receptacle curves ventrally, then extends anteriorly, ending at the triangular plate, the ending point far away the anterior margin of postgastric scutum (Figure 6G, H, I); a very thin, long and line-like structure (lst) can be seen inside the tube.
