Olidiana parafringa , sp. nov.

( Plate 4A , Fig. 196-202 )

Description. Length. Male. 8.20 mm., female unknown.

External morphology. Moderately large, robust species. General color black with dark yellow markings. Forewings with black veins, veins with few dark yellow markings, cells with numerous, irregular light brown markings; mesonotum black with few dark yellow spots; pronotum black, bullae dark yellow; crown light brown, marked with few, suffused dark markings; eyes dark brown; face light yellow; clypeus with reddish brown longitudinal band on inner lateral margins; clypellus with broad, longitudinal brown stripe medially; head distinctly narrower than pronotum, anterior margin obtusely rounded; crown short, narrow, narrower than width of eyes; produced anteriorly about ¼ total length, lateral margins convergent basally; pronotum large, slightly longer medially than crown, surface bullated; mesonotum large, slightly longer medially than pronotum; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrower than clypeus, slightly inflated basally, apex flared laterally.

Male genitalia. Pygofer in lateral view large, sub-triangulate, sparsely setose on ventral apical margin ( Fig. 196 ); aedeagus long, tubular, sinuate in lateral view with subapical, setose process, process elliptical in dorsal view, setae subapical on lateral margin and apically, with 2 small, subapical, digitate lobes in lateral view; gonopore long, basad of apex of process, serrate on outer lateral margin in lateral view ( Fig. 197, 198 ); style long, apophysis broad, lobed apically in dorsal view, outer lateral margin expanded ( Fig. 199, 200 ); dorsal connective, short, narrow, arising from outer margin of aedeagal shaft in dorsal view ( Fig. 197 ); connective large, arms broad, medial ridge complete, stem small, lobate ( Fig. 201 ); subgenital plate slightly longer than aedeagus, broad, sparsely setose on outer lateral margin in distal 1/5 ( Fig. 202 ).

Material examined. Holotype male. LAOS-N: (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) . Paratype male. Same data as holotype ( MLBM).

Etymology. The species name is descriptive for the near similarity of the aedeagal features to O. fringa .

Remarks. From O. fringa to which it is similar in male genitalia features, O. parafringa can be distinguished by the shorter length and configuration of the style which has a larger lobe apically in dorsal view, broader subgenital plate and different arrangement of the setae on the aedeagal process.
