Gyrophaena cognata Cameron, 1939: 106

Gyrophaena setiensis Pace, 2006: 355 syn. nov.

Type material examined: Syntypes of Gyrophaena cognata Cameron 1939: 1 ♂ [dissected; labels as in Fig. 16 ]: ‘Kashmir Gulmarg 8,000 –9,000 ft. vi-vii-1931 Dr. Cameron’, ‘SYN- TYPE’, ‘M. Cameron. Bequest. B.M. 1955– 147.’ ( BMNH); 1 ♀ [dissected]: ‘Kashmir | Gulmarg | 8,000 –9,000 ft. | vi-vii-1931 | Dr. Cameron’ <printed>, ‘SYN- | TYPE’ <round label with blue margin, printed>, ‘M. Cameron. | Bequest. | B.M. 1955–147.’ <printed> ( BMNH); 1 ♂, 1 ♀: ‘Kashmir | Gulmarg | 8,000 –9,000 ft. | vi-vii-[19]31 | Dr. Cameron’ <printed>, ‘SYN- | TYPE’ <round label with blue frame, printed>, ‘M. Cameron. | Bequest. | B.M. 1955–147.’ <printed> ( BMNH). All syntypes with additional handwritten label: ‘ Gyrophaena | cognata Cameron | Enushchenko I.V. | inv. 2019’.

Distribution. India (Kashmir), Nepal.

Remarks. Habitus as in Fig. 10 .

Male. Dorsal plate of aedeagus moderately wide and long, S-shaped, in preapical portion with long, filiform flagellum, folded apically; ventral projection very wide, long, rounded mediodorsally and strongly curved in apical portion, with acute apex and rounded preapical part ( Fig. 11 ); ventral view of the aedeagus see in fig. 43 in Pace (2006). Abdominal tergite VII without tubercles. Apical margin of tergite VIII with three strong, long projections: two lateral projections slightly shorter than median projection ( Fig. 12 ). Apical margin of abdominal sternite VIII slightly concave ( Fig. 13 ).

Female. Abdominal tergite VII as that in male. Apical margin of tergite VIII truncated ( Fig. 14 ). Apical margin of sternite VIII somewhat rounded ( Fig. 15 ).

Pace (2006) described G. setiensis based on a single male from Nepal (‘Prov. Seti, Distr. Bajura, 19 km SW Simikot, Kuwadi Khola…’). Shapes of the aedeagus and male tergite VIII of G. cognata and G. setiensis Pace, 2006 are the same and they are thus conspecific (compare figs 11–12 and figs 41–44 in Pace (2006)). Thus, the latter species was synonymized with G. cognata .
