48 (47) Upper surface of fore wing with a broad bare strip below the marginal vein ; 



and rather sparsely pilose beyond the speculum ..... 49 



Upper surface of fore wing without a bare strip below the marginal vein ; 



disc of wing fairly thickly to rather densely pilose. .... 50 



49 (48) Mesosternum posteriorly, just in front of the trochantinal lobes, clothed with 



long whitish hairs which stand out almost vertically. Head protuberant 

 at level of antennal toruli. Antennae with first funicular segment about 

 1-5 times as long as the second segment, and at least 1-5 times as long as 

 broad CONOMORIUM Masi (p. 821) 



- Mesosternum posteriorly with hairs only slightly outstanding. Head convex, 



but not protuberant, at level of antennal toruli. Antennae with first 

 funicular segment not or hardly longer than the second segment, and 

 slightly transverse .... SCHIZONOTUS Ratzeburg (p. 817) 



50 (48) Posterior half of mesosternum clothed with long, outstanding white hairs 



ERDOESINA Graham (p. 796) 



- Mesosternum with sparse, only slightly outstanding hairs 



CYCLOGASTRELLA Bukovskij (p. 796) 



51 (41) Lower edge of antennal toruli at or even slightly below level of ventral edge 



of eyes ............ 52 



- Lower edge of antennal toruli at least slightly above level of ventral edge of 



eyes 54 



52 (51) Hind corners of propodeum (supracoxal flanges) in dorsal view appearing 



right-angled or even slightly acute ....... 56 



- Hind corners of propodeum in dorsal view rounded or obtuse 53 



53 (52) Postmarginal vein of fore wing only slightly (up to 1-2 times) longer than the 



stigmal vein. Head rather strongly protuberant at level of antennal 

 toruli ............ 46 



- Postmarginal vein obviously longer than the stigmal vein. Head at most 



slightly protuberant at level of antennal toruli ..... 54 



54 (53) Clypeus shiny and nearly smooth, its anterior margin with a median tooth ; 



hind tibia with two spurs ; pronotal collar long, at least one quarter as 

 long as mesoscutum, rounded off in front ; notauli usually traceable to 

 hind margin of mesoscutum, though very superficial posteriorly 



HEMITRICHUS Thomson (p. 826) 



- If the clypeus has a median tooth, then the surface of the clypeus is striate or 



reticulate, the hind tibia has one spur, the pronotal collar is relatively 

 shorter and is often margined, and the notauli are incomplete . . 55 



55 (54) Hind corners of propodeum, in dorsal view, appearing sharp (right-angled or 



acute) ; basal cell of fore wing with scattered hairs over the distal half or 

 more ; hind tibia with two spurs, but the second spur is weaker than the 

 first ; anterior margin of clypeus truncate or curved slightly forwards 



DIMACHUS Thomson (p. 823) 



- Hind corners of propodeum rarely appearing sharp, if so then the basal cell of 



the fore wing is at most pilose at apex, the hind tibia has only one spur, and 



the anterior margin of the clypeus is emarginate medially ... 56 



56 (55) Hind corners of propodeum (supracoxal flanges) in dorsal view appearing 



right-angled or even slightly acute ; propodeal callus sparsely pilose, 

 supracoxal flange bare ; genae curved ; antennal clava pointed, often 

 acutely LARIOPHAGUS Crawford (p. 823) 



- Hind corners of propodeum (supracoxal flanges) nearly always rounded or 



obtuse ; if sharply-pointed, then the propodeal callus and supracoxal 

 flanges are densely pilose, the genae are prominent, almost angled, and the 

 antennal clava is obtuse . . . . . . . . -57
