Vizcaya latifrons, Liang, 2002

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 : 612-614

Vizcaya latifrons sp. nov.

(®gures 5, 42±48)

Female. Length: 6.7 mm.

Externally similar to V. orea (see description of orea given by Asche, 1990: 168) but discal areas of pro- and mesonotum more ochraceous, anteclypeus relatively broad basally, forewings with the brown longitudinal stripe in clavus between common stem of anal veins and inner margin of wing short and distinct only in basal one-half, and metatibial spur with seven teeth (including apical tooth) on inner margin.

Male. Unknown.

Etymology. This species is named for its relatively broad frons.

Material examined. HOLOTYPE, Taiwan: [underside] Horisha [in Japanese], 30 April [19]07; Matsumura ( HUS).

Distribution. Taiwan. This is the ®rst report of Vizcaya species from Taiwan.

Remarks. This species can be distinguished from all other known species in the genus by its 1st antennal segment being well dilated and relatively broad and short, pro- and mesonotum with disc areas more ochraceous, relatively broad anteclypeus, forewings with broad fuscous patch at apical area and short fuscous stripe at apical costal area and metatibial spur with seven teeth (including apical tooth) on inner margin.

Based on the antennae this species forms a group with longispinosa sp. nov., bakeri Muir and orea Asche , all having well dilated and relatively broad and short 1st segment. The discovery of a male and study of the male genitalia of this species are particularly desirable to determine its relationship to other species.
