( Figs 22–26 )

Gyrophaena immatura Kraatz, 1859: 47 ; Motschulsky 1861: 150, Bernhauer & Scheerpeltz 1926: 531, Cameron 1939: 81

Material examined: 4 ♂ # [two specimens dissected; labels as in Fig. 26 ]: ‘ Ceylan 6515–1.’, ‘6515. immatura Kraatz’ ( ZIN) .

Distribution. Sri Lanka.

Remarks. Gyrophaena immatura was originally described from “insula Ceylan ” based on an unspecified number of syntypes. Cameron (1939) redescribed it. During the study of collection of ZIN, the first author found four males possible belonging to the type series.

Habitus as in Fig. 22 .

Male. Dorsal plate of aedeagus wide and moderately short, with very long spirally folded flagellum; ventral projection narrower than dorsal plate, bifurcate in apical portion into ventral elongate projection and dorsal projection, curved in apical part ( Fig. 23 ).

Apical margin of abdominal sternite VIII widely rounded ( Fig. 25 ).
