Canuschiza Lacroix, 1999: 89 , Figs 1 View Figs 1 –27 (original description); LACROIX (2002): 404, Figs 1 View Figs 1 –25 (review); BEZDĚK (2006): 199 (catalogue); LACROIX (2010): 207 (catalogue).

Type species. Canuschiza insularis Lacroix, 1999 , by original designation.

Differential diagnosis. Genus Canuschiza differs from other schizonychine genera in combination of the following characters. Body elongate (length 7.5–17.2 mm), almost parallel-sided, weakly to moderately convex. Labrum transverse, deeply bilobed, lobes rounded. Clypeus transverse, anterior angles rounded. Fronto-clypeal suture present, forming continuous shallowly bisinuate line or better visible elevated double fronto-clypeal carina ( Figs 1A,B View Figs 1 ). Occipital carina missing. Eyes small (width of both eyes combined lower than maximum width of frons between eyes) to large (width of both eyes combined larger than maximum width of frons between eyes). Antenna with eight to ten antennomeres; club with three antennomeres. Terminal maxillary palpomere elongate, truncate apically. Pronotum transverse, simply convex, without anteromedian tubercle. Basal border complete, anterior border missing. Posterior angles of pronotum broadly rounded to rectangular, in some species even distinctly produced posteriad. Elytra weakly to moderately convex, parallel-sided, rounded apically, apical angle approximately rectangular. Striae missing, except of feebly visible sutural stria. Macropterous, rarely micropterous. Protibia narrow, tridentate, terminal calcar inserted against medial dent. Claws bifid, with ventrobasal teeth (e.g. Fig. 2B View Figs 2 ). Parameres symmetrical, regularly curved in lateral aspect, rounded apically in dorsal aspect; apex with tuft of long yellowish macrosetae ( Figs 10A–D View Figs 10 , 11A–D View Figs 11 ).
