Acanthaclisis inquinata Gerstaecker, 1885: 11 . 2556.

Syngenes inquinatus (Gerstaecker) : Navás 1912: 166. 549.

Syngenes longicornis inquinatus (Gerstaecker) : Handschin 1963: 224. 2832.

Type Depository: EMAU. Holotype: female (badly damaged).

Type locality: Congo (unspecified locality).

Diagnosis. The holotype ( Figs 73–75 ) is badly damaged and discolored, most of the abdomen and antennae are missing. Forewings heavily marked with an apical streak and large spots at the posterior margins. Costal area with biaereolate cells from before origin of Rs, one in right wing, two in left forewing and a series of biaereolate cells from Rs to pterostigma.

Type material examined. Holotype ♀, labelled “ inquinatus Gerst. * Congo Stdgr. ( Staudiger )”/ “ Zool. Mus. Greifswald II 27416”. ( EMAU).

Distribution. Congo.

Comments. Syngenes inquinatus is distinguished from S. debilis by its larger size, more heavily marked wings and fewer biaereolate cells before Rs, and from S. medialis by the biaereolate cells from before Rs and an unbroken series of biaereolate cells from Rs2 to pterostigma. Syngenes maritimus is very similar to this species, but is separated primarily by the disjunct distribution of the two populations.
