( Plate 4H View PLATE 4 , Fig. 245-251 View Figures 245-251 )

Description. Length. Male 10.62 mm., female unknown.

External morphology. Large, somewhat slender species. General color dark brown with numerous small yellow spots on dorsum except head; crown light brown with 2 brown stripes medially, 2 suffused spots near anterior margin; eyes dark brown; face yellow with reddish brown stripe on inner lateral margins; clypellus light reddish brown; head distinctly narrower than pronotum, anterior margin obtusely rounded; crown short, broad, about as wide as width of pronotum, produced anteriorly about ¼ distance beyond anterior margin of eyes, convergent basally; eyes large, elongate ovoid; pronotum large, about half longer than crown; mesonotum large, slightly longer medially than pronotum; clypeus long, narrow, lateral margins broadly convex; clypellus narrow, slightly inflated longitudinally in middle, apex flared laterally.

Male genitalia. Pygofer in lateral view elongate triangulate, sparsely setose apically ( Fig. 245 View Figures 245-251 ); aedeagus with shaft long, narrow, tubular, sinuate with long, bifurcate, setose apical processes, 2 spurs basally in dorsal view, moderately long spine apically, projecting laterally in lateral view ( Fig. 246, 247 View Figures 245-251 ); style with long, robust apophysis ( Fig. 248, 249 View Figures 245-251 ); dorsal connective long, narrow ( Fig. 246, 247 View Figures 245-251 ); connective large, anterior arms somewhat narrow, medial ridge complete, stem small, sub-quadrate ( Fig. 250 View Figures 245-251 ); subgenital plate long, broad, sinuate with few, short microsetae apically ( Fig. 251 View Figures 245-251 ).

Etymology. The species name is descriptive for wing-like arms of the connective.

Remarks. From O. bispiculata to which it is similar in aedeagal features, O. pennata can be distinguished by the broader aedeagal processes, lack of caudoventral process on the pygofer, narrow anterior arms of the connective and by the more robust stylar apophysis.
