Etymology.

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

Diagnosis.

The new species is similar to K. mahmolae sp. n., but can be distinguished by the proportion of the cymbiobulbus (length/maximal width = 3) (Figure 1I), the flat, wide and elongated lobe of the embolus complex (clo, Figure 2B, D) and the absence of long, strong setae on the abdominal scutum in males, and the presence of a crescent-shaped plate (pl, Figure 3G, I) of the endogyne.

Description.

Male (holotype). Habitus as in Figure 1A, C, E. Body length 1.59; carapace 0.75 long, 0.67 wide; abdomen 0.78 long, 0.51 wide.

Palp (Figure 1 I–K): Femur 0.32 long, 0.17 width, length/maximal width = 1.88. Cymbiobulbus 0.57 long, 0.19 wide, length/maximal width = 3. Embolus complex (Figure 2B, D, F) with four projections from prolateral view, including a flat, wide and elongated, 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 retrolaeral view, the distal end with filiform lobe (fil).

Female. Habitus as in Figure 3A, C, E. Body length 1.61; carapace 0.69 long, 0.62 wide; abdomen 0.94 long, 0.65 wide. Postgastric scutum 0.40 long, 0.46 width, length/width ratio = 0.87.

Genitalia. Ventral view (Figure 3I): middle part of anterior margin of postgastric scutum strongly sclerotized (asr), with a narrow, crescent-shaped plate (pl). Dorsal view (Figure 3J): with a T-shaped sclerite (tsc) anteriorly, followed posteriorly by a tube-like posterior receptacle (pr); from lateral view, the tube curved ventrally, then extends anteriorly, ending at the crescent-shaped plate, the ending point nearly reaching anterior margin of postgastric scutum (Figure 3G, H, I); a very thin, long and line-like structure (lst) can be seen inside the tube.

Distribution.

Myanmar (Kachin State).
