ASIACOELOTES , NEW GENUS

TYPE SPECIES: Coelotes xinhuiensis Chen, 1984 .

ETYMOLOGY: The generic name derives from its similarity to Coelotes and distribution in East Asia, and is masculine in gender.

DIAGNOSIS: This genus resembles Draconarius in having an elongated cymbial furrow, a long, slender embolus, and long, strongly convoluted spermathecae. Females can be distinguished by the broad, closely situated spermathecae (figs. 70, 71), males by the absence of the conductor dorsal apophysis (figs. 72–74).

DESCRIPTION: See description of type species (below).

DISTRIBUTION: China, Japan, Korea (map 2).

COMPOSITION: Fifteen species are included, all are new combinations. Three new synonyms are recognized.

1. Asiacoelotes acco (Nishikawa, 1987) : male holotype, male and female paratypes from Komori­ana Mine, Utobara, Futtsu­shi, Chiba, Japan, in NSMT and in the Arachnological Society of Japan, not examined. NEW COMBINATION (transferred here from Coelotes ).

2. Asiacoelotes dicranatus ( Wang et al., 1990) : female holotype and male paratype from Jiangsu, China, in HBI, examined. NEW COMBINATION (transferred here from Coelotes ).

The species Coelotes cinctus Zhu et al., 1993 , with male and female paratypes from Dandong, Liaoning, China, in IZB, examined, is placed as a junior synonym of A. dicranatus (because of the identical male and female genitalic morphology). NEW SYNONY­ MY.

The species Coelotes paradicranatus Song et al., 1993 , with male paratypes from Qingyuan, Liaoning, in IZB, examined, is placed as a junior synonym of A. dicranatus (because of the identical male genitalic morphology). NEW SYNONYMY.

3. Asiacoelotes ensifer ( Wang and Ono, 1998) : male holotype and female paratype from Nantou, Taiwan, in NSMT, examined. NEW COMBINATION (transferred here from Coelotes ).

4. Asiacoelotes illustratus ( Wang et al., 1990) : male and female paratypes from Changsha, Hunan, China, in HBI, examined. NEW COMBINATION (transferred here from Coelotes ).

5. Asiacoelotes insidiosus (L. Koch, 1878) : male holotype from Japan, depository unknown, not examined. Male and female specimens from Japan, in CAS, AMNH, and SMF, examined. NEW COMBINATION (transferred here from Coelotes ).

The species Coelotes curtus ( Bösenberg and Strand, 1906) : female holotype from Saga, Japan, in SMF, examined, is placed as a junior synonym of A. insidiosus (L. Koch) (because of the identical female genitalic morphology). NEW SYNONYMY.

6. Asiacoelotes interunus (Nishikawa, 1977) : male holotype, male and female paratypes from Minoo, Osaka, Japan, in the Osaka Natural History Museum and in the Arachnological Society of Japan, not examined. One male specimen from Japan, in ZMB, examined. NEW COMBINATION (transferred here from Coelotes ).

9. Asiacoelotes pengi ( Ovtchinnikov, 1999) : female holotype from Yuelushan, Changsha, Hunan, China, in HBI, examined. NEW COMBINATION (transferred here from Coelotes ). This species was initially described as Coelotes ovatus by Peng and Wang (1997), p. 330, and is a homomym of C. ovatus Paik, 1976 .

10. Asiacoelotes songminjae ( Paik and Yaginuma, 1969) : female holotype from Yeongchi­gul Cave, Korea, in NSMT, not examined. Male and female specimens from Korea, in KAI and AMNH, examined. NEW COMBINATION (transferred here from Coelotes ).

11. Asiacoelotes tengchihensis ( Wang and Ono, 1998) : female holotype from Mt. Tengchih, Tao­Yuan­hsinang, Kaohsiung, Taiwan, in NSMT, examined. NEW COMBINATION (transferred here from Coelotes ).

13. Asiacoelotes xinhuiensis ( Chen, 1984) : female holotype and female paratype from Xinhui, Guangdong, China, in HTC, examined. NEW COMBINATION (transferred here from Coelotes ).

14. Asiacoelotes yaeyamensis (Shimojana, 1982) : male holotype, male and female paratypes from Banna­dake, Ishigaki, Okinaea, Japan, in the Arachnological Society of Japan and in Shimojana’s personal Collection, Japan, not examined. NEW COMBINATION (transferred here from Coelotes ).

15. Asiacoelotes yushanensis ( Wang and Ono, 1998) : female holotype from Tatachia,

Nantou, in NSMT, examined. NEW COMBINA­ TION (transferred here from Coelotes ).
