Diagnosis. Closely resembles K. pomo sp. nov. in the genital morphology, especially the ventral view of male embolus; however, from the embolus, K. frenata can be stably distinguished from K. pomo sp. nov. by the absence of a retro-dorsal keel (RD) and the proximal end of the pro-dorsal keel (PD) only extends to proximal 1/4 position of the embolus ( Figs 4E View FIGURE 4 , 11E View FIGURE 11 ; vs. on the embolus of K. pomo sp. nov., RD is absent, and PD extends almost to the base of the embolus, see Figs 9E View FIGURE 9 , 11F View FIGURE 11 ); furthermore, the male palpal tibia of K. frenata lacks long and white setae on the retrolateral side ( Fig 10B View FIGURE 10 ; vs. K. pomo sp. nov. has those setae in the same position, see Fig. 10F View FIGURE 10 ). Females differ from K. pomo sp. nov. in having a relatively wide and distinct, slightly sclerotized septum of atria ( Figs 4C View FIGURE 4 , 12A–F View FIGURE 12 ; vs. the septum of K. pomo sp. nov. is not sclerotized and appears as a narrow slit, see Figs 9C View FIGURE 9 , 12G–H View FIGURE 12 ). Both sexes can also be distinguished from K. pomo sp. nov. by the lateral pale bands on the body having relatively indistinct edges.

Additional description. Male. Measurements of CL / OL / OW for different individuals: MHBU-ARA-00026901 (3.18 / 1.32 / 1.79), MHBU-ARA-00027529 (3.23 / 1.33 / 1.76), MHBU-ARA-00026902 (2.81 / 1.21 / 1.66), MHBU-ARA-00026903 (2.54 / 1.07 / 1.46), MHBU-ARA-00026909 (2.71 / 1.19 / 1.61). Legs of MHBU-ARA-00027529: I 7.25 (2.02, 1.48, 1.71, 1.28, 0.76), II 4.97 (1.48, 0.94, 1.01, 0.90, 0.64), III 4.63 (1.27, 0.79, 0.94, 1.01, 0.62), IV 6.09 (1.73, 1.01, 1.48, 1.22, 0.65); leg formula 1423. Carapace with relatively irregular bands formed by relatively dense white scales on dorsal lateral sides, extending longitudinally from behind ALEs to posterior edge; small cluster of sparse white scales in front of fovea and behind gap between AMEs, respectively; dark yellow, inconspicuous scales sparsely covering entire dorsal side ( Fig. 3A View FIGURE 3 ). Abdomen. Ventral side with inclined white scale bands near posterior on lateral sides ( Fig. 3E–G View FIGURE 3 ). Leg spination. Femur I: pd 2 (ca. 1/3 down from distal); tibia I: pv 3, rv 3; metatarsus I: pv 2, rv 2; femur II: pd 1, (1/5 down from distal); tibia II: v 2, pv 1; metatarsus II: pv 2, v 2; femur III: pd 1 (1/4 down from distal); metatarsus III: v 1 (on distal); metatarsus IV: v 1 (on distal); other segments leg parts spineless. Palp. Bright from dense white scales and long white setae, white scales on dorsal of patella, tibia and distal of femur, pro-dorsal side of proximal of cymbium, long white setae on prolateral and retrolateral of patella, distal of femur, prolateral side of tibia and proximal of cymbium ( Fig. 10A–C View FIGURE 10 ). Embolus initially vertical from basal plate, subsequently inclining retrolaterally from proximal 1/3; with one keel each on retro-ventral (RV) and pro-dorsal (PD) sides, PD edge irregular, extending from proximal 1/4 position of embolus to about middle ( Fig. 11E View FIGURE 11 ); RV translucent, edge relatively smooth, extending from proximal 1/4 up to subapical of embolus, terminating sharply at a precipitous decline ( Fig. 11A, C View FIGURE 11 ). RTA base broad, narrowing distally to small rounded apex not exceeding proximal 1/2 of cymbium.

Female. Measurements of CL / OL / OW for different individuals: MHBU-ARA-00026899 (3.14 / 1.32 / 1.80), MHBU-ARA-00026900 (3.56 / 1.41 / 1.93), MHBU-ARA-00026904 (3.46 / 1.37 / 1.95), MHBU-ARA-00026905 (3.75 / 1.53 / 2.08), MHBU-ARA-00026910 (3.78 / 1.53 / 2.14), MHBU-ARA-00026911 (3.33 / 1.33 / 1.87). Legs of MHBU-ARA-00026910: I 7.08 (2.03, 1.62, 1.57, 1.06, 0.70), II 5.38 (1.62, 1.09, 1.17, 0.85, 0.65), III 5.32 (1.51, 0.99, 1.06, 1.09, 0.67), IV 7.16 (2.07, 1.22, 1.79, 1.37, 0.71); leg formula 4123. Overall pattern like male, besides paturon lacking white scales ( Fig. 3L View FIGURE 3 ) and abdomen lacking dorsal sclerotized area ( Fig. 3D View FIGURE 3 ). Leg spination as in male, besides lacking pv spine on tibia II. Epigyne. Rim of atria shallow, extending down and fused to septum ( Figs 4C View FIGURE 4 , 12A–F View FIGURE 12 ). median part of spermathecae close to each other, separating and expanding into ellipsoid shape towards distal end. Accessory glands short, with length slightly longer than width. Fertilization ducts close to proximal position of spermathecae ( Figs 4D View FIGURE 4 , 12K–P View FIGURE 12 ).

Variation. Carapace length (CL) ranging from 2.54 to 3.23 in males (n = 5), 3.14 to 3.78 in females (n = 6). Spination. One male (MHBU-ARA-00026901) with three pd spines on its left femur I ( Fig. 3Q View FIGURE 3 ), whereas other individuals of both sexes with only two at the same position. Abdomen pattern variations see Fig. 3E–J View FIGURE 3 .

Distribution. China (Guangdong, Guangxi, Hainan, Hongkong).
