Etymology:
The specific name is from Latin
macilentus
(macilent), in reference to the habitus of this species; adjective.
Diagnosis:
This species resembles
K. miaoshanensis
sp. nov.
in having similar male chelicerae (Figs 31B–C, 35B–C) and similar ventral view of female genital area (Figs 30A, 32B, 34A, 36C), but can be distinguished by the small sawtooth of procursus in retrolateral view (Figs 29B, 31D), the different distal elements of procursus (Figs 29A–B, D; 31A, D; 32A), and the shape of pore plates of epigynum (Figs 30B, 32C). This species also resembles
K. dongkou
sp. nov.
,
K. flabelliformis
sp. nov.
and
K. wangae
sp. nov.
in having similar ventral view of female genital area (Figs 6A, 8C, 14A, 16C, 30A, 32B, 59A, 60A), but can be distinguished by the shape of male chelicerae (Figs 31B–C), the different distal elements of procursus (Figs 29A–B, D; 31A, D; 32A), and the shape of pore plates of epigynum (Figs 30B, 32C).
Description: Male (
holotype
):
Total length 2.05 (2.15 with clypeus), prosoma 0.76 long, 0.84 wide, opisthosoma 1.29 long, 1.03 wide. Leg I: 18.87 (4.75 + 0.45 + 4.65 + 6.55 + 2.47), leg II: 12.41 (3.48 + 0.42 + 3.27 + 4.07 + 1.17), leg III: 8.98 (2.55 + 0.33 + 2.24 + 2.95 + 0.91), leg IV: 11.73 (3.45 + 0.35 + 2.95 + 4.05 +
0.93); tibia I L/d: 44. Habitus as in Fig. 29C. Dorsal shield of prosoma yellowish, with black margins and black median stripe behind ocular area; sternum black. Legs yellowish, with slightly darker rings on femora (subdistally) and tibiae (proximally and subdistally). Opisthosoma grey with large black spots dorsally and ventrally. Ocular area slightly elevated and separated from prosoma, thoracic furrow shallow but distinct; distance PME-PME 0.12; diameter PME 0.13; distance PME-ALE 0.02; AME absent. Sternum slightly wider than long (0.53/0.51). Chelicerae as in Figs 31B–C, with pair of long, hooked frontal apophyses (distance between tips: 0.09); pair of strong proximal apophyses provided with lateral elliptic ledges, with lateral small sawtooth-shaped ledges, without modified hairs; pair of small ledges on frontolateral surface distally. Palps as in Figs 29A–B; 31A, D; trochanter with retrolateral apophysis and small ventral projection, femur with retrolateral apophysis, patella large, procursus simple proximally but complex distally, with small sawtooth in retrolateral view, bulb simple, no other projections except for embolus. Retrolateral trichobothrium of tibia I at 13%; legs with short vertical hairs on all metatarsi (mostly dorsally and laterally), without spines and curved hairs; tarsus I with more than 30 pseudosegments, only about 16 distinct ones distally.
Variation:
Tibia I in other males (n=20, leg I lost in the other
four specimens
): 4.04–4.87 (mean: 4.57).
Female:
Similar to male, habitus as in Figs 30C–D. Tibia I in females (n=55, leg I lost in the other
four specimens
): 3.33–4.70 (mean: 4.23). Genital area brown (Figs 30A, 32B), with internal structures nearly invisible through cuticle, apparently without pockets. Dorsal view of epigynum (Figs 30B, 32C) with two pore plates.
Distribution:
The species is known from two localities in Xingping Town (
Fig. 61
).
