Olidiana lata , sp. nov.

( Plate 4B , Fig. 203-209 )

Description. Length. Male 8.26-8.40 mm., female 9.44 mm.

External morphology. Moderately large, slender species. General color black with numerous yellow spots except on head; crown light brown with black markings; eyes dark brown; face yellowish; clypeus with dark orange stripe on inner lateral margins; clypellus dark brown, sometimes suffused on genae; head distinctly narrower than pronotum, anterior margin obtusely angled; crown short, moderately broad, about as wide as width of eyes, produced anteriorly about ¼ distance beyond anterior margin of eyes; eyes semiglobular; pronotum moderately large, slightly longer medially than crown, surface bullated; mesonotum large, about half longer than pronotum; forewings with venation typical; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, inflated medially from base to near apex, apex flared apically.

Male genitalia. Pygofer in lateral view narrow, triangulate, glabrous ( Fig. 203 ); aedeagus moderately long, tubular, sinuate in lateral view, with long apical process, process in lateral view with rectangular spur subbasally, short row of short setae subapically to apex, with dorsal sub-triangulate process basally ( Fig. 204, 205 ); style with long, very robust apophysis, in lateral view, long triangulate flange on outer lateral margin from middle to near apex ( Fig. 206, 207 ); dorsal connective moderately long, narrow ( Fig. 204, 205 ); connective large, anterior arms wide, medial ridge incomplete, stem small, sub-quadrate ( Fig. 208 ); subgenital plate long, narrow, tapered apically with several, short microsetae on lateral margins in distal 1/6 ( Fig. 209 ).

Material examined. Holotype male. LAOS-N: Phongsaly Prov., 21 o 41-2’ N 102 o 06 -8’E., 28.v.-20vi. 2003, Phongsaly envir., 1500 m., Vit Kuban, leg. / Entomological Expedition , Laos 2003, Moravian Museum, Brno, Czech Republic ( MMBC) . Additional material examined. 9 males, 1 female, same data as holotype ( MMBC) ; 1 male, 1 female, same data as holotype ( MLBM) ; 8 males, Phongsaly prov. , 21 o 21'N 102 o 03’E, Ban Sano Mai env., 19-26.v. 2004, 1150 m., Vit Kuban, leg. ( MMBC) ; 17 males, Louang Phrabang prov. , 20 o 33-4' N 102 o 4' E., Ban Song Cha (5 km. W), 1200 m., Vit Kuban, leg. ( MMBC) ; 6 males, Louang Namtha pr., 21 o 09' N 101 o 19’E, Namtha-Muang Sing, 5-31.v.1997, 900- 1200 m., Vit Kuban, leg. ( MMBC) .

Etymology. The name of the species is descriptive for the broad, lateral flange on the outer margin of the stylar apophysis.

Remarks. Among species having an entire aedeagal apical process, not bifurcate, O. lata can be distinguished from them by the subbasal rectangulate spur and apical setae on the aedeagal process, and by the broad flange on the apophysis of the style.
