Diagnosis.
Among its close
Pholcus
relatives (see the remark of
P. clavatus
), this species is very similar to
P. zhangae
sp. nov.
in the shapes of the palpal bulb, both with branched appendices of palpal bulb (
Figs. 20H
and
63I
).
P. kangding
sp. nov.
can be distinguished from the latter by the shape of the procursus (
Figs. 20G–I
), by the smaller club-shaped epigynal apophysis (
Fig. 20A
), and by the cephalic region without brown slender central marks (
Fig. 20C
).
Etymology.
The species name refers to the
type
locality. It is a noun in apposition.
Description.
Male (
holotype
): total body length 4.2: cephalothorax 1.3 long, 1.5 wide; abdomen 2.9 long, 1.6 wide. Leg I: 41.7 (10.8+0.7+10.2+17.5+2.5), tibia II: 6.7, tibia III: 4.2, tibia IV: 5.4; tibia I L/D: 64. Prosoma shape as in
Fig. 20C
. Carapace short, broad and almost circular, ochre, with pair of brown mark broadly connecting to ocular area. Cephalic region raised, without brown central marks, ocular area dark yellow. Clypeus 0.46, dark ochre, without marks. Distance AME–AME 0.06. Diameter AME 0.09, ALE 0.14, PME 0.12, PLE 0.13. Chelicerae as in
Fig. 20E
, with pair of black apophyses distally, pair of unsclerotized nipple-like apophyses proximolaterally and pair of small unsclerotized rounded apophyses proximocentrally. Labium light yellow. Endites slightly gray. Sternum dark gray, with irregular yellow patches centrally and laterally as in
Fig.
20F
. Femora, patellae and tibiae ochre, with dark rings, metatarsi and tarsi brown. Abdomen cylindrical, pale ochre, dorsum with small brown patterns as in
Fig. 20C
. Venter pale brown. Palps as in
Figs. 20H and 20I
, bulb with fan-like uncus, appendix with a median branch. Procursus as in
Fig. 20G
. Tarsal organ capsulate.
Variation.
Tibia I in five other males: 9.4–10.0 (mean: 9.7). Body length in five other males 4.0–4.2.
Female: in general very similar to male. Total length of bodies 4.1–4.7. A specimen measured (
paratype
), total length 4.7: cephalothorax 1.2 long, 1.3 wide; abdomen 3.5 long, 1.8 wide. Tibia I: 6.5. Distance AME–AME 0.05. Diameter AME 0.08, ALE 0.13, PME 0.11, PLE 0.12. Epigynum roughly oval as in
Fig. 20A
, with a bottle-cork-shaped apophysis on the top. Dorsal view as in
Fig. 20B
, with M-shaped sclerotized arch anteriorly and a pair of oval pore plates.
Distribution.
Known from
type
locality only.
