Liang, Ai-Ping, 2002, New taxa of Vizcayinae (Hemiptera: Auchenorrhyncha: Delphacidae), including a remarkable new genus from China, Journal of Natural History 36 (5), pp. 601-616 : 612

Vizcaya aschei sp. nov.

(®gures 7, 60±64)

Length: 6.0 mm.

Externally similar to V. vindaloa Asche (see description of vindaloa given by Asche, 1990: 174) but forewings (®gure 7) with the apical fuscous patch very narrow, slender, evenly broad and nearly C-shaped, the apical margin and the apical inner margin hyaline, and the fuscous longitudinal stripe in clavus between common stem of anal veins and inner margin very short, small and nearly triangular and metatibial spur with nine teeth (including apical tooth) on inner margin.

Male genitalia with pygofer (®gures 60, 61) short and high, long ventrally and short dorsally in lateral aspect, laterodorsal edges relatively broadly produced caudad, without teeth subapically on dorsal margin; median projection of ventrocaudal margin (®gure 63) moderately long, slightly V-shaped distally in ventral aspect; anal tube short, broad, somewhat rounded, and apical margin incised medially in dorsal view, anal styles very short, small and slender (®gure 62); parameres (®gure 60) relatively narrow and slender, nearly S-shaped in lateral aspect, distinctly broad subbasally, apical one-third evenly broad, apex slightly acute; aedeagus (®gure 64) with shaft long and slender, depressed ventrodorsally, with two slender, ventrally directed, spinose processes apically, one relatively long, reaching near midlength of the shaft, the other short.

Etymology. This new species is named in honour of Dr Manfred Asche, Museum fuÈr Naturkunde der Humboldt-Universit aÈt zu Berlin, Germany for his very valuable contribution to the world delphacid systematics and for whose pioneering work on the Vizcayinae has made this work possible.

Distribution. Southern India.

Material examined. HOLOTYPE, South India: Madras State , Anamalai Hills, Cinchona, 1067 m, May 1959 (P. S. Nathan) ( CAS) . PARATYPE: South India: 1, Madras State , Nilgiri Hills, Devala, 675 m, May 1961 (P. S. Nathan) ( CAS) .

Remarks. This species is similar to another Indian species, V. vindaloa , but can be distinguished by the characters noted in the above description.
