Forficuloecus emersoni Guimarães

( Fig. 5 )

Forficuloecus emersoni Guimarães, 1985: 42 . Type host: Alisterus chloropterus (E.P. Ramsay, 1879) , the Papuan King Parrot.

Male. Tergal setae: II–III, 7–8; IV–VII, 9–11; VIII, 6–8. Tergite IX with median bridge connecting lateral portions, as in Fig. 7 . Sternal setae: II, 5–12; III–VI, 6–15; VII, 4–6. Genitalia ( Fig. 5 ) with parameres shaped as shown and isolated darkly pigmented medioposterior structure of kidney-bean shape.

Female. Tergal setae: II, 8; III, 8–9; IV–VII, 8–11; VIII, 6–8. Sternal setae: II, 8–10; III, 8–14; IV–VI, 7– 12; VII, 4–8.

Material. Ex A. chloropterus , NEW GUINEA: Holotype male, allotype female of F. emersoni ( KCEM), Bulolo, 3 Mar. 1962, H. Clissold; 1 male, 2 females ( UMSP), Bulolo River, BBM-NG 27880, P. Shanahan; 1 male ( UMSP), Wau, 27 Feb. 1963, BBM-NG 20349, H. Clissold.

Remarks. While very similar to F. c a m e ro n i, the male of F. emersoni differs in the shape of the parameres, the characteristic kidney-bean shape of the penis, and the presence of a bridge connecting the lateral portions of tergite IX. Females of these two species are very close, with F. emersoni having a total of 23– 33 setae on sterna IV–VI.
