Holocneminus huangdi Tong & Li, 2009, sp. nov.

Description

Holocneminus huangdi sp. nov.

Figs 20–23, 48–53

Type material: Holotype male, 14 males and 13 females paratypes, CHINA: Hainan Province, Dongfang City, Huangdi Cave (18°57.720´N, 109°08.373´E), 20 March 2005, Y. Song, X. Han, Y. Tong and G. Deng leg.; 3 females paratypes, CHINA: Hainan Province, Changjiang County, Qicha Town, Baoyao Cave (19°06.092´N, 109°01.208´E), 2–3 April 2005, collector same as for holotype.

Etymology: The specific name is a noun in apposition, taken from the type locality.

Diagnosis: The new species can be easily distinguished from Holocneminus piritarsis Berland, 1942 (Beatty 2008) by the absence of two-horned projection on clypeus, the shape of palpal bulb and the complicated procursus in male; by the presence of a short scape on epigynum in female.

Description: Male (holotype). Total length 1.96 (2.2 with clypeus), carapace width 0.96. Leg 1: 8.02 (2.12+0.31+2.16+2.68+0.75), tibia 2: 1.78, tibia 3: 1.5, tibia 4: 1.97; tibia 1 L/d: 23. Habitus as in figs 20 and 21. Carapace yellow with wide median brown mark. Ocular area yellow, but brown laterally, thoracic groove distinct; sternum yellowish, shape as in fig. 22. Opisthosoma pale gray, with some spots dorsally and laterally. Distance PME-PME 0.1; diameter PME 0.09; distance PME-ALE 0.03; diameter AME 0.03. Chelicerae as in fig. 50, with stridulatory files, and a pair of strongly sclerotized frontal apophyses and two pairs of small cones proximolaterally. Palps as in figs 48, 49 and 51; bulbus with distinctive internal duct; femur conspicuously enlarged; procursus relatively huge and complicated. Retrolateral trichobothrium of tibia 1 at 54%; Legs without spines, curved and vertical hairs; tarsus 1 with about 6 pseudosegments.

Variation. Tibia 1 in other males (n = 14): 1.98–2.34 (mean: 2.19)

Females. In general similar to male. Tibia 1 in females from Huangdi Cave (n = 31): 1.87–2.53 (mean: 2.19); from Baoyou Cave (n = 3): 1.96, 2.03 (leg I lost in one specimen). Epigynum as in figs 23 and 52, with a short scape pointing posteriorly. Lateral surface of scape with pair of pockets, possibly to accommodate the male cheliceral apophyses during copulation. Dorsal view as in fig. 53.
