Thagria freytagi , sp nov.

( Plate 1H , Figs. 50–56 )

Length Male 9.10 mm; female unknown.

External morphology. Large, robust species. General color dark brown to black with reddish areas on dorsum, crown with 4 transverse color bands: anterior margin black, ivory transverse band near middle, black band below, broad red band basally; pronotum with 3 black bands: narrow black anterior margin, narrow ivory band below anterior margin, remainder broad black band with orange bullae; mesonotum with anterior angles reddish brown, large irregular shaped brown spot on ivory background medially, apex yellow; forewings with numerous yellow spots, veins with pronounce longitudinal spots ( Plate 1H ); face with 5 transverse color bands: anterior margin black, followed by narrow yellow and black bands, broad yellow band followed by narrow black band across base of clypeus, clypellus yellow. Head large, narrower than pronotum, anterior margin rounded; crown very broad, wider than eye width, produced distally about ¼ length beyond anterior margin of eyes, lateral margin convergent basally, disk depressed; eyes large, semiglobular; pronotum short, median length less than median length of crown, surface bullated; mesonotum large, about 1/3 longer than pronotum; forewings broad in apical 1/3, apex obliquely truncate; clypeus long, broad, slightly depressed transversely about middle; clypellus large, wider basally than apex of clypeus, distinctly inflated in basal half, abruptly narrowed in apical half, apex rounded.

Male genitalia. Pygofer in lateral view with caudoventral lobe moderately long, caudodorsal margin with a pair of short digitate lobes ( Fig. 50 ); segment X in dorsal view with exposed pair of moderately long, apically bifurcate ventral processes ( Figs. 50, 55 ); aedeagus symmetrical, short, reaching to about midlength of ventral paraphysis ( Figs. 51, 52 ); ventral paraphysis asymmetrical, robust, apex pointed with 2 well sclerotized, robust spines basally on same lateral margin ( Figs 51, 52 ); style very short, extending slightly beyond base of ventral paraphysis in dorsal view, with long arm basally, seen in dorsal view ( Figs. 53, 54 ); connective typical; dorsal connective in dorsobasal view broadly U-shape, rami long, attached distally to base of ventral process of segment X, stem absent ( Fig. 55 ); subgenital plate typical, apex with tuft on long setae ( Fig. 56 ).

Material examined. Holotype male. LAOS-N. (Oudomaxai), 1–9.v.2002, 1100m. 20° 45’N – 102° 09’E, OUDOM XAI (17 km. NEE), Vit Kuban leg., Collection Moraviske, Brno. ( BRNO).

Etymology. This species is named for Paul Freytag for his contributions on Coelidiinae of Thailand.

Remarks. This species belongs to a distinctive group that has beautifully colored transverse bands on head and face. From multipars (Walker) which it is similar in certain male genitalia features, freytagi can be distinguished by 2 basal spines that are on the same lateral side of the paraphysis (asymmetrical, single in multipars ) and apically bifurcate processes on segment X (entire in multipars ).
