Type material.

Holotype ♂ (SYNU-640), China, Yunnan Prov., Baoshan City, Longling Co., Longxin Town, Xiaoheishan Nature Reserve, 16.02.2011, Z. Li & L. Wang; Paratypes: 1♀ (SYNU-641), 1♀ (SYNU-642), 4 ♀ (SYNU-643-646), same data as for the holotype.

Diagnosis.

The new species can be distinguished from K. mahmolae and K. putao by the strongly elevated epigastric region of the male (arrow in Fig. 1F View Figure 1 ) vs. flat (see Tong et al. 2018: figs 1C, E, 4E, G), triangular bulb (Fig. 2A, B View Figure 2 ) vs. nearly rectangular (see Tong et al. 2018: figs 2A, 4I), and the nearly heart-shaped postgastric scutum of the female (Fig. 3C View Figure 3 ) vs. rectangular (see Tong et al. 2018: figs 3G, 6G).

Description.

Male (holotype). Habitus as in Fig. 1A, C View Figure 1 . Body length 1.96; carapace 1.03 long, 0.86 wide; abdomen 1.01 long, 0.59 wide. Body yellow, legs lighter. Carapace (Fig. 1B, E View Figure 1 ): broadly oval in dorsal view, with large brown oval patches (coxal apodemes) behind eyes, longer than ½ of carapace; pars cephalica strongly elevated, pars thoracica higher than pars cephalica, surface of pars cephalica smooth; lateral margin straight, smooth, rebordered. Mouthparts (Fig. 1D, G View Figure 1 ): chelicerae straight; labium rectangular, anterior margin deeply incised; endites broad, distally branched. Abdomen (Fig. 1A, C, F View Figure 1 ): ovoid; booklung covers smooth; sperm pore small, oval, situated at level between anterior spiracles; anterior and posterior spiracles connected by furrow; epigastric region strongly elevated; dorsal scutum covering entire dorsum, strongly sclerotized; epigastric scutum strongly sclerotized, surrounding pedicel; postgastric scutum strongly sclerotized, long, almost rectangular, covering nearly the full length of the abdomen, with posteriorly-directed lateral apodemes. Palp (Figs 1H-J View Figure 1 , 2A-G View Figure 2 ): strongly sclerotized; trochanter with a ventral protuberance (vp); femur 0.23 long, 0.14 width, length/maximal width = 1.64; cymbiobulb 0.41 long, 0.16 wide, length/maximal width = 2.56; psembolus complex (Fig. 2E, F, G View Figure 2 ) with flat, wide and elongated, strongly curved lobe (clo), leaf-like projection (llp), broom-like projection (blp), and long, brush-like projection (bpr) in prolateral view; with large ear-shaped lobe (lel) in retrolateral view.

Female. As in male except as noted. Habitus as in Fig. 3A, C, E View Figure 3 . Body length 1.93; carapace 1.51 long, 0.78 wide; abdomen 1.15 long, 0.62 wide. Labium and endites unmodified. Abdomen (Fig. 3A, C View Figure 3 ): dorsal scutum large, covering more than 5/6 of dorsum; postgastric scutum heart shaped. Epigastric area (Fig. 3C, G View Figure 3 ): surface unmodified. Endogyne (Fig. 3H View Figure 3 ): with T-shaped sclerite (tsc) anteriorly, followed posteriorly by tube-like posterior receptacle (pr).
