Neobelocera asymmetrica Ding and Yang , in Ding et al. 1986:420, Fig. 6, 1–7 ; Ding, 2006: 196, Fig. 98, A–G.

Description. The descriptions are reproduced from Ding and Yang (Ding et al. 1986) and Ding (2006). “Length of body 1.90 mm (male), 2.00 mm (female); including forewing 2.80 mm (male), 3.20 mm (female); tegmen length 2.20 mm (male), 2.60 mm (female).”

Coloration. “Vertex pale brown. Frons brown, except the broad transversal stripe between ocelli and the narrow stripe near apex yellowish white, along inner side of lateral carinae and near apex of median carina, with several short transversal stripes, dark brown. Genae coloration same as in frons at same area, but with 2 to 3 pale brown spots medially. Antennae brown. Clypeus blackish brown, pale basally. Pro- and mesonotum with the areas between lateral carinae pale brown, outer sides of lateral carinae blackish brown. Thorax with ventral areas, including most part of coxae of legs blackish brown, the rest of legs with blackish brown and yellowish brown intervally. Forewing pale yellowish white, costal margin with a fuscous marking basally, apical half with irregular markings. Abdomen blackish brown, except margin areas of each segment yellowish brown. ”

Head and Thorax. “Head including eyes wider than pronotum (1.11:1). Vertex wider at base than long submedially about 2.5:1. Frons longer in middle line than wide at widest part about 1.5:1. Antennae with first segment longer than wide at apex about 0.5:1, shorter than second segment about 0.63:1. Pronotum shorter than vertex (about 0.9:1). Mesonotum longer than pronotum and vertex combined (2.1:1). Forewing longer in middle line than wide at widest part about 2.83:1.”

Male Genitalia. “Male anal segment ( Ding et al. 1986: Fig. 6 : 4) small, lateral lobe long and acute. Pygofer in caudal view ( Ding et al. 1986: Fig. 6 : 3, 7) with opening larger in length than width, ventral margin incised narrowly. Aedeagus ( Ding et al. 1986: Fig. 6 : 3, 7) tubular, curved, rounded at apex, process of phallobase slender, long and curly, spine-like. Genital styles in caudal view ( Ding et al. 1986: Fig. 6 : 7) parallel, touching each other at apex, in profile ( Ding et al. 1986: Fig. 6 : 5) with apex slightly curved dorsad, ventral margin with a small process at apical 1/3.”
