Description

Vizcaya longispinosa sp. nov.

(®gures 3, 4, 15 ±18, 24±27, 40, 41, 54 ±59)

Length: 6.4 mm; 6.5±6.7 mm

Externally similar to V. orea Asche (see description of orea given by Asche, 1990: 168). Metatibial spur with 8±11 teeth (including apical tooth) on inner margin (number of teeth varying among individuals and on left and right legs).

Male genitalia with pygofer (®gures 54, 55) in lateral view trapezoid, in caudal view circular, ventrally about 1.5 3 longer than dorsally, laterodorsal edges relatively broadly produced caudad, with three small teeth subapically on dorsal margin; distance between ventral angles relatively small; median projection of ventrocaudal margin relatively long, comparatively narrow, distally with nearly U-shaped incision in ventral view (®gure 58); anal tube relatively large and broad, expanded laterad mesially, lateroapical angles not produced into ventrally directed processes; anal style slender; parameres (®gure 56) relatively broad, sinuous and slightly S-shaped in lateral aspect, gradually tapering from base to apex, apical part acute in lateral view; aedeagus (®gure 59) with shaft elongate, slender, depressed ventrodorsally, arched in lateral aspect, with two long, slender, ventrally directed, spinose processes apically on left and dorsal side: left process long, longer than one-half total length of theca, dorsal spine base bifurcate.

Etymology. This species is named for its relatively long apical spinose processes on the aedeagus.

Material examined. HOLOTYPE, China: Yunnan, Xishuangbanna, Menga, 1050±1080 m, 6 June 1958 (S.-Y. Wang) (IZCAS). PARATYPES: China: 7, Yunnan, Xishuangbanna, Yunjinghong, 850 m, 25 June 1958 (L.-Y. Zheng) (5 in IZCAS; 2 in BMNH).

Distribution. South-west China (Yunnan). This is the ®rst report of Vizcaya species from mainland China.

Remarks. This species is similar to V. orea but diOEers in having the metatibial spur with 8±11 teeth (including apical tooth) on inner margin and the aedeagus with relatively slender apical spinose processes with the left one long, longer than onehalf total length of theca.
