Remarks.

The author ( Zhang 1992: 337) compares the genus with pantropical Stenotarsus Perty, 1832 which contains about 250 recent species that are highly variable in body shape. A combination of characters similar to those of Palaeoendomychus may be found, for example, in Endomychidae and Nitidulidae ( Kolibáč and Huang 2008).

Original description.

" Body minute and compact, oval, hairless. Head deeply sunk into pronotum. Eyes rather large, widely separated, slightly prominent. Antennae short, flagellum cylindrical. Pronotum transverse, short (Chin.: raised at centre), without membrane [sic] in front, but with lateral sides (Chin. “edges”) broadly flattened, posterior angles prominent. Scutellum small, narrowly triangular, distinctly longer than broad. Elytra wide, dehiscent, as wide at base as pronotum, and both closely connected to one another, humeral angles rounded, terminal angles prominent, surface with striae. Legs normal, with tarsi short and narrow (Chin. 3 tarsomeres visible), first and second tarsal segments triangular, each about as long as wide, third cylindrical, noticeably longer than wide. " ( Zhang 1992: 334, 337.) After Kolibáč and Huang (2008).
