Ganaspidium, Weld, 1955

Buffington, Matthew, 2010, A revision of Ganaspidium Weld, 1952 (Hymenoptera, Figitidae, Eucoilinae): new species, bionomics, and distribution, ZooKeys 37 (37), pp. 81-101 : 87-88

Key to species of Ganaspidium

Note: Diffuse light, such as that produced by fluorescent lights or fiber optic lights with light dispersing film, is absolutely essential to effectively use this key.

1. Frons smooth, malar space, and mesopleuron smooth ( Fig. 2B ); if malar space striate, striations restricted to ventral margin and not extending to ventral margin of compound eye; if mesopleuron with some striations, these striations restricted to the postero-dorsal margin of the sclerite .................. 2

– Frons, malar space and the majority of the mesopleuron distinctly longitudinally striate Figs 3A & B ); frons typically striate from mandibular base to ventral margin of compound eye............... G. konzaensis Buffington , sp. n.

2. Dorsal surface of scutellar plate with a pair of distinct tubercles present on the anterior half of the plate (Fig. 1A).............................................................. 3

– Dorsal surface of scutellar plate nearly flat, with a slight hump where in other species the scutellar plate tubercles are present ( Fig. 4A )............................... ..................................................................... G. kolmaci Buffington , sp. n.

3. Dorsal surface of the scutellum entirely smooth, occasionally with weak wrinkles along the margin of posterior carina ( Fig. 4D ) ............................. 4

– Dorsal surface of scutellum distinctly rugulose to strigose, never smooth ( Fig. 2B )................................................................................................... 5

4. Posterior margin of scutellum without a distinct carina differentiating the dorsal surface from the postero-lateral surface; dorsal surface of scutellum totally smooth............................................... G. eldiablo Buffington , sp. n.

– Posterior margin of scutellum with a distinct and well-developed posterior carina, differentiating the dorsal surface of the scutellum from the postero-lateral surface; dorsal surface of scutellum smooth, with occasional weak wrinkles posteriorly along the posterior carina.............. G. flemingi Buffington , sp. n.

5. Dorsal surface of scutellum distinctly rugulose with a large, distinctly cleft, posterior carina ( Fig. 4C ); tubercles of the scutellar plate massive, height of tubercle equal to the width of the tubercle base; malar space striate.............. .................................................................... G. didionae Buffington , sp. n.

– Dorsal surface of scutellum more delicately sculptured, with fine strigae radiating from the underside of the scutellar plate ( Fig. 2 B ); posterior carina very thin and not cleft; tubercles of the scutellar plate smaller, height of each tubercle equal to one-half to one-third length of tubercle base; malar space occasionally striate but much more typically smooth......... G. pusillae Weld
