Etymology:
The specific name is from Latin
flabelliformis
(fan-shaped), in reference to the shape of pore plates of epigynum; adjective.
Diagnosis:
This species resembles
K. dongkou
sp. nov.
,
K. macilenta
sp. nov.
,
K. miaoshanensis
sp. nov.
and
K. wangae
sp. nov.
in having similar ventral view of female genital area (Figs 6A, 8C, 14A, 16C, 30A, 32B, 34A, 36C, 59A, 60A), but can be distinguished by the narrow dark median line behind ocular area (Figs 13C, 14C), the different distal elements of procursus (Figs 13A–B, D; 15A, D; 16A), and the nearly inverted fan-shaped pore plates of epigynum (Figs 14B, 16B).
Description: Male (
holotype
):
Total length 2.37 (2.56 with clypeus), prosoma 0.77 long, 0.96 wide, opisthosoma 1.60 long, 1.28 wide. Leg I: 21.81 (5.51 + 0.46 + 5.64 + 7.70 + 2.50), leg II: 15.03 (4.24 + 0.44 + 3.85 + 5.05 + 1.45), leg III: 11.33 (3.34 + 0.37 + 2.76 + 3.80 + 1.06), leg IV: 14.18 (4.16 + 0.40 + 3.65 + 4.96 + 1.01); tibia I L/d: 52. Habitus as in Fig. 13C. Dorsal shield of prosoma yellowish, with black margins and narrow dark median line 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 0.13; diameter PME 0.12; distance PME-ALE 0.02; AME absent. Sternum slightly wider than long (0.60/0.57). Chelicerae as in Figs 15B–C, with pair of long, hooked frontal apophyses (distance between tips: 0.12); pair of strong proximal apophyses and sclerotized angular apophyses proximocentrally, respectively, without modified hairs; pair of small ledges on frontolateral surface distally. Palps as in Figs 13A–B; 15A, D; trochanter with retrolateral apophysis and small ventral projection, femur with retrolateral apophysis, patella large, procursus simple proximally but complex distally, bulb simple, no other projections except for embolus. Retrolateral trichobothrium of tibia I at 11%; legs with short vertical hairs on all metatarsi
Variation:
Tibia I in other males (n=5): 5.06–5.90 (mean: 5.44).
Female:
Similar to male, habitus as in Figs 14C–D. Tibia I in females (n=18, leg I lost in the other specimen): 4.55–5.38 (mean: 5.07). Genital area brown (Figs 14A, 16C), with internal structures nearly invisible through cuticle, without distinct pockets. Dorsal view of epigynum (Figs 14B, 16B) with two nearly inverted fan-shaped pore plates.
Distribution:
The species is known only from the
