Calodia vincula , sp. nov.

( Plate 1C , Fig. 28-32 )

Description. Length. Male 6.50-6.60 mm., female unknown.

External morphology. Medium size, robust species. General color black throughout except for dark brown eyes and light brown crown, with a single broad, yellow transverse band on base of forewings below apex of mesonotum; head narrower than pronotum, anterior margin broadly rounded; crown broad, slightly broader than width of eyes; slightly produced beyond anterior margin of eyes, lateral margin convergent basally; eyes large, semiglobular; pronotum large, slightly longer medially than crown, surface sparsely bullated; mesonotum moderately large, about half again longer than pronotum; clypeus long, broad in basal half, slightly tapered apically; clypellus long, narrow, about 1/3 longer than clypeus, median longitudinal ridge, apex flared laterally.

Male genitalia. Pygofer in lateral view triangulate, sparsely setose apically ( Fig. 28 ); aedeagus asymmetrical, shaft narrowly tubular in dorsal view in distal 3/4 with 2 subapical processes, distal one glabrous, basal one with row of spines on lateral margin and 1 very long spine apically ( Fig. 29, 30 ); style moderately long ( Fig. 31 ); dorsal connective very long, very narrow ( Fig. 30 ); connective large, membranous arms narrow, slightly tapered ( Fig. 31 ); subgenital plate inflated medially on outer lateral margin, glabrous ( Fig. 32 ).

Material examined. Holotype male. VIETNAM: Tam Dao N. P., 25-28.VIII. 2010, I. G. 31668/ Day Catch. Leg. J. Constant and P. Limbourg ( IRSNB) . Paratype, 1 male, CHINA: Kouy Tchéou, Abbé Lárgeteau, Museum Paris, R. Oberthur 1898 ( NMHN).

Etymology. The name is descriptive for the very long, slender dorsal connective attached to the aedeagus that serves as a fulcrum for movement of the aedeagus.

Remarks. This species can be distinguished from the group of species with 1 glabrous and 1 spinose process by the long process which has a row of spines on lateral margin with a very long spine apically.
