Olidiana bispiculata , sp. nov.

( Plate 4F , Fig. 231-237 )

Description. Length. Male 8.12-9.00 mm., female unknown.

External morphology. Moderately large, slightly robust species. General color dark brown to black with numerous small, yellow spots on forewings, mesonotum and pronotum; crown and eyes light to dark brown; face light yellow with 2 light to dark orange stripes on inner lateral margins of clypeus; clypellus light to dark orange; head narrower than pronotum, anterior margin obtusely rounded; crown narrow, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/ 3 as long as clypeus, narrow, apex flared laterally.

Male genitalia. Pygofer in lateral view broadly triangulate, sparsely setose on upper ventral margin ( Fig. 231 ); aedeagus with shaft narrowly tubular, with recurved bifurcate apical process, each arm with subbasal spur and lateral to apical setae in distal ¼; gonopore subapical ( Fig. 232, 233 ); style with very long, slender apophysis, obliquely striate, long spine apically ( Fig. 234, 235 ); dorsal connective very long, narrow ( Fig. 232, 233 ); connective large, anterior arms broad, with medial ridge, stem short, subquadrate ( Fig. 236 ); subgenital plate long, broad, tapered apically, glabrous ( Fig. 237 ).

Material examined. Holotype male. LAOS-N: Louanphrabang, 11-21.v.2002, 19 o 35' N 101 o 58' E., Thong Khan, 75 m., Vit Kuban, leg. ( MMBC) . Paratypes: 1 male, same data as holotype ( MLBM) ; 6 males (Oudomxai), 1-9.v.2002, 1100 m., 20 o 45' N 102 o 09' E, Oudom Xai , 17 km. NEE, Vit Kuban, leg. / Entomological Expedition , “ Laos 2002”, Moravian Museum, Brno, Czech Republic ( MMBC) .

Etymology. The name of this species is descriptive for the 2 basal spurs on the aedeagal process.

Remarks. This species is distinguished from relatives that possess a single, bifurcate, apical aedeagal process by the 2 basal spurs attached on each arm and by the style with oblique striations and apical spine on the apophysis.
