Genus Fritzruehlia Schmidt, 1924 View in CoL

Fritzruehlia Schmidt, 1924: 22 View in CoL . Type species: Fritzruehlia longifrons Schmidt, 1924 View in CoL , by original designation.

= Heterothionina Lallemand, 1942 View in CoL ( type species: Heterothionina gibbosa Lallemand, 1942 View in CoL ): 5, syn. fide Synave, 1957: 53.

Diagnosis. Metope long and narrow, 3.5–4.0 times as long as wide medially, parallel-sided, with only median carina running from its upper margin to metopoclypeal suture ( Figs 3 View FIGURES 1–3 , 6 View FIGURES 4–8 ). Anteclypeus large, flattened laterally, with protruding apex ( Fig. 4 View FIGURES 4–8 ). Fore wings elongate, hunchbacked in its basal thirds (in dorsal view), with a wide subcostal field in its basal third; clavus as long as whole wing, open; vein branching sequence: R 4, M 9–10, CuA 2 ( Figs 1, 2 View FIGURES 1–3 , 8 View FIGURES 4–8 ). Hind wings well developed, as long as fore wings. Legs not flattened neither foliated. Hind tibia with three lateral spines. First and second metatarsomeres short, nearly equal in length, with sparse long setae ventrally. First metatarsomere with two latero-apical and five intermediate spines. Second metatarsomere with only two latero-apical spines.

Composition and distribution. Three species known from the Democratic Republic of the Congo ( Schmidt 1924; Lallemand 1942; Synave, 1957; current data) ( Fig. 9 View FIGURE 9 ).

Comparison. Apparently Fritzruehlia is closely related to Ingoma Fennah, 1954 within the tribe Trienopini according to strongly flattened laterally anteclypeus, with protruding apex ( Fig. 4 View FIGURES 4–8 ) (Gnezdilov, in press). Comparison of male genitalia structure of the species of both genera is needed for confirmation of this opinion.
