Key to the species of Asphalmus

1. Rostrum short, 1.37‒1.40 times as wide as long, equally wide at base and at apex. Basal half of rostrum indistinctly tapered anteriorly ( Fig. 8 ). Frons matt. Pronotum matt, finely punctate ( Fig. 24 ). Larger species, 3.6‒4.1 mm. ...................... A. japonicus Sharp, 1896

– Rostrum longer, 1.16‒1.25 times as wide as long, at base wider than at apex. Basal half of rostrum distinctly tapered anteriorly ( Figs. 14, 20 ). Frons shiny. Pronotum shiny, coarsely punctate ( Figs. 25‒26 ). Smaller species, 3.0‒ 3.6 mm. .................................................... 2

2. Elytral adherent setae dense, elongate, drop-shaped, creating distinct stripes on elytral intervals ( Fig. 26 ). Scutellum very small, hardly visible ( Fig. 26 ). Antennal funicle of males shorter, antennomere 2 1.8 times as long as wide, antennomeres 3–7 wider than long. Dent on profemur small, half the size of the tooth at the internal angle of the protibia ( Fig. 26 ). Aedeagus symmetrical, pointed just on apex ( Fig. 22 ). 3.0 mm. ......... A. sharpi sp. nov.

– Elytral adherent setae scarce, piliform, indistinct on intervals ( Fig. 25 ). Scutellum large, and prominant ( Fig. 25 ). Antennal funicle of males longer, antennomere 2 2.4‒2.5 times as long as wide, antennomeres 3–7 longer than wide. Dent on profemur large, somewhat longer and twice the size of the tooth of the internal angle of the protibia ( Fig. 25 ). Aedeagus distinctly asymmetrical, pointed in the whole apical half ( Fig. 17 ). 3.2‒3.6 mm. .... ...................................................................................................... A. ovatus ( Sharp, 1896)
