Nielson, M. W., 2015, A revision of the tribe Coelidiini of the Oriental, Palearctic and Australian biogeographical regions (Hemiptera: Cicadellidae: Coelidiinae), Insecta Mundi 2015 (410), pp. 1-202 : 42-43

Olidiana egregia (Schumacher) , n. comb.

( Plate 3 G, H , Fig. 183-188 )

Description. Length. Male 8.20 mm., female 9.40 mm.

External morphology. Moderately large, robust species. General color black to dark brown with 2 broad, yellow transverse bands on forewings; mesonotum and pronotum black; crown light brown; eyes dark brown; face in male black, in female brown; head narrower than pronotum, broadly rounded anteriorly; crown short, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; clypeus long, broad, lateral margins broadly convex; clypellus in male obscured by glue, short, narrow in female. (Female body slightly teneral.)

Male genitalia. Pygofer in lateral view large, sub-triangulate, small digitate caudoventral lobe mesally, small lobe apically, few setae apically ( Fig. 183 ); aedeagus with long bifurcate, subapical process, one with row of secondary setae, one glabrous ( Fig. 184, 185 ); style in dorsal view elongate, curved near middle ( Fig. 186 ); dorsal connective long, narrow ( Fig. 184 ); connective large, anterior arms broad, medial ridge absent, stem small, sub-quadrate ( Fig. 187 ); subgenital plate long, broad in basal 1/5, membranous stripe in apical 1/5 on inner lateral margin ( Fig. 188 ).

Female seventh sternal segment. Length about twice as long as penultimate segment, posterior margin truncate, slightly sinuate, slightly teneral.

Material examined. Jassus egregius Schumacher. Lectotype male, here designated: Formosa (Taiwan), Kosempo, H. Sauter, 1911 / 7. IV / Eberswalde, Coll. EDI / Jassus egregius Schumacher , Typen (in Schumacher’s handwriting), P. Schumacher det. / Syntypus (Red label) / DE Hemimetabola, #100093 (White label) / DEI Müncheberg, Hemi - 0001 (Green label). Jassus egregius Schumacher , syntype female, Formosa (Taiwan), Kosempo, Formosa, H. Sauter 1911 / 7. V. / Schumacher, det. / Eberswalde Coll., DEI / Syntypus (Red Label) / DEI Hemimetabola #100094 / DEI Müncheberg, Hemi – 00002 ( DEI).

Remarks. The species is a member of the O. brevis (Walker) species complex. Distinguishing features which separate O. egregia from related species are found in Table 2 and illustrated in Figures 1-12 . Two “ syntypes ” of Jassus egregia Schumacher were located in the Senckenberg Deutsches Entomologische Institute in Müncheberg, Germany. The handwritten “Typen” label attached to the male specimen by Schumacher may be considered an important issue which may or may not impact the lectotype designation.
