Caterino, Michael S. & Tishechkin, Alexey K., 2008, A review of Hippeutister Reichensperger with new species from California and Costa Rica (Coleoptera: Histeridae: Hetaeriinae), Zootaxa 1895, pp. 39-52 : 40

Key to the species of Hippeutister

1 Elytral disc bearing setae ( Figs. 1 A, 1C, 4A, 4C).......................................................................................2

- Elytral disc glabrous; epipleura may be setose............................................................................................3

2 Setae of elytron (in part) clearly marking the basal portions of elytral striae 1–3 as well as sutural stria, otherwise evenly distributed ( Figs. 1 C, 4C); dorsal setae borne in elevated pustules, somewhat flattened, faintly scale-like ( Figs. 4 C, 5C) .................................................................................. H. castaneus (Lewis)

- Setae of elytron more randomly scattered, not obviously marking any elytral striae, and denser in posterior half ( Figs. 1 A, 4A); setal bases not elevated, setae finer, not at all scale-like ...... H. californicu s n. sp.

3 Elytral epipleuron and lateral pronotal margin bearing dense rows of setae ( Figs. 5 B, 8B) H. solisi n. sp.

- Elytral epipleuron and lateral pronotal margin glabrous.............................................................................4

4 Body moderately convex ( Figs. 8 A–C); elytron with sutural stria marked by row of distinctly larger punctures; pronotum with few or no superficial wrinkles on surface ................................................................... ............................................................................. H. plaumanni Reichensperger and H. amabilis (Wenzel)

- Body strongly convex ( Fig. 8 D); elytron densely punctate, but punctures in area of sutural stria not standing out; pronotum with distinct transverse to oblique wrinkles in anterior corners ( Fig. 5 D) ...................... .................................................................................................................................... H. manicatus (Lewis)
