PLATYSTETHYNIUM Ogloblin, 1946 View in CoL View at ENA

( Figs 222–231 View FIGURES 222–224 View FIGURES 225, 226 View FIGURES 227–229 View FIGURES 230, 231 )

Platystethynium Ogloblin, 1946: 290 View in CoL . Type species: Platystethynium onomarchicidum Ogloblin, 1946 View in CoL , by original designation.

Platypatasson Ogloblin, 1946: 293 View in CoL . Type species: Platypatasson fransseni Ogloblin, 1946 View in CoL , by original designation. Synonymy under Cleruchus View in CoL by Schauff, 1984: 43; synonymy under Platystethynium View in CoL by Donev & Huber, 2002: 118; revised status as subgenus under Platystethynium View in CoL by Huber et al., 2020: 289 (Nearctic genera and catalogue).

Pseudocleruchus Donev & Huber, 2002: 118 View in CoL . Type species: Pseudocleruchus triclavatus Donev & Huber, 2002 View in CoL , by original designation. Synonymy under Platystethynium View in CoL by Ortis et al., 2020: 10.

Diagnosis. Body dorsoventrally flattened; face strongly produced anteriorly, in lateral view head almost triangular; female antenna with funicle segments about as long as wide and clava 2- or 3-segmented ( Figs 223 View FIGURES 222–224 , 228 View FIGURES 227–229 ); fore wing narrow, parallel sided or almost so ( Figs 224 View FIGURES 222–224 , 229 View FIGURES 227–229 ); ovipositor short, originating in about apical half of gaster ( Figs 226 View FIGURES 225, 226 , 231b View FIGURES 230, 231 ).

Discussion. Platystethynium belongs to the Cleruchus group of genera. In the Afrotropical region the Cleruchus group also includes Cleruchoides , Cleruchus and Eubroncus . Huber et al. (2020) had placed Platystethynium in the Anagrus group because of the longitudinally divided frenum but on balance of features it is better placed in the Cleruchus group. In Platystethynium (Platystethynium) the clava is 3-segmented ( Fig. 228 View FIGURES 227–229 ) whereas in Platystethynium (Platypatasson) the clava is 2-segmented ( Fig. 223 View FIGURES 222–224 ); both subgenera occur in the Afrotropical region.

Afrotropical hosts. Unknown.

Distribution. No named species in the Afrotropical region. Specimens examined are from Guinea, Ivory Coast and Nigeria (CNC).
