Calphurnioides Distant 1913

Diagnosis. Recognized by the following combination of characters: head and pronotum shining with sparse silky setae; wool-like pile absent; pterostigma barely surpassing apex of discal cell (Fig. 3); M and Cu basal of discal cell conspicuously dark brown, sometimes connected by a dark brown pigment spot giving the appearance of a subbasal cell; scutellum tuberculate or simple; metanotum with large spine; 2nd abdominal tergite (1st visible) simple; two-segmented foretarsi.

Distribution. C alphurnioides is known from tropical Africa and the Seychelles, but is most diverse in southeast Asia and the west Pacific.

Remarks. As currently conceived, Calphurnioides appears monophyletic with the possible exception of C. gressitti Wygodzinsky. However, several Australian species of Emesopsis will key out to Calphurnioides using Wygodzinsky’s keys due to his reliance on the subquadrate subbasal cell in diagnosing the genus (e.g. Wygodzinsky 1966).
