FEMORACOELOTES , NEW GENUS

TYPE SPECIES: Coelotes platnicki Wang and Ono, 1998 .

ETYMOLOGY: The generic name is derived from Coelotes and the special femoral characteristics of the male palp (the presence of distal apophysis and of a cluster of tiny setae prolaterally), and is masculine in gender.

DIAGNOSIS: Females of this genus can be easily recognized by the absence of epigynal teeth and the broad copulatory ducts (figs. 227, 228), males by the presence of a femoral apophysis and the absence of a median apophysis (figs. 229–231).

DESCRIPTION: See description of type species (below).

DISTRIBUTION: China (map 9).

COMPOSITION: Two species are included in this genus.

1. Femoracoelotes latus ( Wang, Tso, and Wu, 2001) : male holotype, male and female paratypes from Nantou, Taiwan, in THU, examined. NEW COMBINATION (transferred here from Coelotes ).

2. Femoracoelotes platnicki ( Wang and Ono, 1998) : male holotype and female paratype from Mt. Tengchih, Paoshan­tsun, Taoyuan­hsiang, Kaohsiung­hsien, Taiwan, in NSMT, examined. NEW COMBINATION (transferred here from Coelotes ).

Femoracoelotes platnicki (Wang and Ono) Figures 227–241

Coelotes platnicki Wang and Ono, 1998: 148 , figs. 15–19 (male holotype and female paratype from Mt. Tengchih, Paoshan­tsun, Taoyuanhsiang, Kaohsiung­hsien, Taiwan, in NSMT, examined). – Song et al., 1999: 377.

DIAGNOSIS: Differs from F. latus in the shape of the atrium and the broad copulatory ducts of females (figs. 227, 228) and by the slightly bifid femoral apophysis and the different conductor shape of males (figs. 229– 231).

DESCRIPTION: Total length 6.00 –8.00. From front, anterior eye row slightly procur­ ved, posterior row procurved; eye sizes and arrangements: AME smallest, PLE largest, PME slightly smaller than PLE, ALE slightly smaller than PME; AME­AME subequal to AME­ALE, ALE­PLE close together, PME­ PLE separated by roughly PME diameter or slightly less, PME­PME subequal to AME­ AME or slightly longer. Clypeal height roughly 1.5 AME diameter; chilum divided, elongated (fig. 232). Chelicerae with three promarginal and four retromarginal teeth (occasionally five) (fig. 233). Labium with length subequal to width. Length of female 1st leg patella + tibia shorter than carapace length.

Tarsal organ situated away from distal end of tarsus, close to third distalmost trichobothrium (figs. 234, 235). Apex of ALS with 2 major ampullate gland spigots (MAP), about 24–25 piriform gland spigots in both sexes; PMS with 1 or 2 minor ampullate gland spigots (mAP) in both sexes, about 16– 18 aciniform gland spigots in both sexes, 2 cylindrical gland spigots (CY) in female; PLS with about 16 aciniform gland spigots in female and 21 in male, 2 cylindrical gland spigots in female, 1 spigot of examined male PLS also shaped like cylindrical gland spigot (figs. 236–241).

Epigynum without epigynal teeth; atrium relatively small; copulatory ducts broad, membranous; spermathecal heads apparent; spermathecae short, convoluted, widely separated, with indistinct stalks and bases (figs. 227, 228). Male palp with femoral apophysis distally, a cluster of tiny setae prolaterally; patellar apophysis short, ventrally curved; RTA almost as long as tibia, with distal end not extended beyond tibia; lateral tibial apophysis absent; cymbial furrow short; conductor broad, complex, strongly modified; conductor lamella small; conductor dorsal apophysis relatively ventrally situated, long, slender; median apophysis absent; embolus basal in origin, strong, moderately long, with apex modified (figs. 229–231).

MATERIAL EXAMINED: CHINA: Taiwan: Kaohsiung­hsien , Taoyuan­hsiang , Paoshantsun, Mt. Tengchih, 1550–1800 m alt., November 1, 1989, 5 males and 7 females (H. Ono, NSMT, NSMT­Ar.3421) ; Kaohsiunghsien , Taoyuan­hsiang , Paoshan­tsun, Mt. Tengchih, 1550 m alt., November 1, 1989, 1 male (H. Ono, NSMT, NSMT­Ar.3430) ; Kaohsiung­hsien, Taoyuan­hsiang, Paoshan­tsun,

Mt. Tengchih, 1550–1800 m alt., November 1, 1989, male holotype and female paratype (H. Ono, NSMT, NSMT­Ar.3421).

DISTRIBUTION: China (Taiwan).

HIMALCOELOTES , NEW GENUS 1

TYPE SPECIES: Himalcoelotes martensi , new species.

ETYMOLOGY: The generic name refers to its similarity to Coelotes and to the locality of type species, and is masculine in gender.

DIAGNOSIS: Females resemble those of Urocoras in having elongated epigynal teeth, but differ in having short copulatory ducts (fig. 265, 266); males resemble those of Draconarius in having the patellar apophysis and the conductor dorsal apophysis, but differ in the shape of the median apophysis (small, rounded, medially notched and then strongly extended) (figs. 244, 267, 268).
