Diagnosis. Body length 330–1040 μm. Head in lateral view with face strongly projecting anteriorly, with a sharp angle (about 90°) between dorsal and ventral surfaces and toruli just dorsal to angle ( Figs 280 View FIGURES 279, 280 , 284a View FIGURES 281–286 , 295 View FIGURES 293–298 ); vertex with ocelli in a low, wide triangle, the lateral ocelli at posterolateral angles next to posterior apex of supraorbital trabecula ( Figs 281 View FIGURES 281–286 , 296 View FIGURES 293–298 ); funicle segments quadrate ( Fig. 285 View FIGURES 281–286 ) to wider than long; clava 1-segmented ( Figs 280 View FIGURES 279, 280 , 285 View FIGURES 281–286 ); frenum entire ( Fig. 287 View FIGURES 287, 288 ); fore wing narrow and parallel-sided, with widest point at posterior lobe opposite or just distal to venation ( Figs 279 View FIGURES 279, 280 , 292 View FIGURES 291, 292 ); ovipositor short, less than half length of gaster ( Figs 290 View FIGURES 289, 290 , 305 View FIGURES 304–310 ).

Discussion. Cleruchus and Platystethynium ( Platypatasson) belong in the Cleruchus group of genera, which consists of species with rather dorsoventrally flattened bodies, claval segments quadrate or shorter than wide ( Figs 285 View FIGURES 281–286 , 805 View FIGURES 804–806 ) and head in lateral view triangular, with face strongly projecting anteriorly ( Figs 280 View FIGURES 279, 280 , 284 View FIGURES 281–286 , 295 View FIGURES 293–298 , 800 View FIGURE 800 , 804 View FIGURES 804–806 ) so toruli are well anterior to the mouthparts. This group could be treated a subgroup within a larger Anagrus group of genera depending on which features are used to define the group. Cleruchus differs from Platystethynium ( Platypatasson) by the clava 1-segmented (entire) clava.
