Mongoliana Distant, 1909

Fig. 8

Mongoliana Distant, 1909: 87 .

Type species: Hemisphaerius chilocorides Walker, 1851 , by original designation.

Diagnosis

Coryphe 1.5 times as wide as long, with median carina. Metope slightly longer than wide, a little widened below antenna, with or without a linear series of very small tubercles along lateral margin. Metopoclypeal suture straight. Tegmen widened at basal costal margin, veins inconspicuous, claval suture absent. Hind wing 0.7–0.8 times length of tegmen, distinctly reticulate in distal part. Anal tube nearly cup-shaped. Pygofer with hind margin convex medially. Aedeagus with pair of ventral processes. Gonostyle with hind margin weakly or distinctly concave, caudo-ventral angle widely rounded.

Distribution

China, Japan, Indonesia (Sula Islands).

Remarks

Fourteen species are included in Mongoliana , of which nine were examined in NWAFU. Type specimens of H. chilocorides (BMNH(E) 1705797) and H. recurrens (BMNH(E) 1705798) were also examined and their images are provided here. Although no material of Hemisphaerius contusus is available for study and the type could not be found in BMNH, the species is transferred to Mongoliana based on its original description which states: “front darker along each side is adorned with a row of little yellow tubercles” and “fore-wings widened on the border at the base near which they are slightly concave”. Similarly, the specimen of this species recorded by Butler (1875) from Sula Islands could also not be found in BMNH, where other Butler specimens are deposited.
