Khorata diaoluoshanensis , new species

( Figs. 1 J–L, 5A–G)

Material examined. – Holotype: male ( IZCAS), Diaoluoshan Natural Reserve , Hainan Island, China, coll. Y. Song, X. Han and Y. Tong, 19 Apr.2005.

Paratypes: 7 males and 14 females ( IZCAS), same data as holotype .

Diagnosis. – The new species is similar to K. schwendingeri Huber, 2005 , and K. bangkok Huber, 2005 , but can be easily distinguished by the longer proximal apophyses of the male chelicerae, and by the shape of the distal elements of the procursus; from the other two species of this genus, K. khammouan Huber, 2005 , and K. jaegeri Huber, 2005 , by the male chelicerae (distal apophyses close together), the male palpal bulb (absence of hump or projection retrolaterally), and by the distal elements of the procursus.

Description. – Male (holotype). Total length 2.25 (2.4 with clypeus), carapace width 1.12. Leg 1: 22.28 (5.67+0.42+5.37+8.35+2.47), tibia 2: 3.3, tibia 3: 2.4, tibia 4: 3.17; tibia 1 L/d: 54. Habitus as in Fig. 1J and 1K . Carapace ochre with black margins and dark mark behind ocular area; sternum black. Legs ochre, with slightly darker rings on femora (subdistally) and tibiae (proximally and subdistally). Opisthosoma gray with large black spots, also ventrally. Ocular area slightly elevated and separated from carapace, thoracic furrow shallow but distinct; distance PME-PME 0.14; diameter PME 0.14; distance PME-ALE 0.02; AME absent. Clypeus unmodified. Sternum slightly wider than long (0.67/ 0.58). Chelicerae as in Fig. 5D and 5E , with pair of long frontal apophyses (distance between tips: 0.1), strong proximal apophyses provided with scales, and pair of small, nearly transparent apophyses at frontolateral surface and basal part of proximal apophyses, respectively, without modified hairs. Palps as in Fig. 5A, 5B and 5C ; trochanter with retrolateral apophysis and small ventral projection, femur with retrolateral apophysis, patella very large, procursus relatively simple except distally, bulb very simple, no projection apart from embolus. Retrolateral trichobothrium of tibia 1 at 7%; legs without spines, vertical hairs, and curved hairs; tarsus 1 with barely visible pseudosegments, only about 10 distinct distally.

Variation. Tibia 1 in other males (n = 7): 5.25–5.92 (mean: 5.59).

Females. In general similar to male. Tibia 1 in females (n = 14): 4.82–5.53 (mean: 5.12). Epigynum simple brown plate, with internal structures nearly invisible through cuticle ( Figs. 1L and 5F ), apparently without pockets. Dorsal view as in Fig. 5G .

Etymology. – The specific name refers to the type locality.

Distribution. – Hainan, China (present study).
