Remarks. Based on the following characters Oreosecus is congeneric with Tapinomorphus : structure of rostrum with base of epifrons as wide as space between borders of eyes, separated from head by slender V-shaped stria, without developed epistome, with moderately shiny frons, slender long antennal scapes reaching anterior border of pronotum, metatibiae lacking corbels and claws fused. Thus Oreosecus Marshall, 1950 is a junior synonym of Tapinomorphus Hartmann, 1904 , syn. nov.

Within the genus, Tapinomorphus porculus is most similar to T. alpinus Voss, 1962 based on the following characters: elytra without bumps or elevated intervals, rostrum without middle longitudinal carina and funicular segments 1 and 2 equally long. Tapinomorphus porculus can be distinguished from T. alpinus by dorsal part of body sparsely clothed with very short recumbent setae, without scales (vs. elytra and pronotum densely covered with short oval appressed scales in T. alpinus ), elytra with sparse row of very short erect setae, shorter the half the width of one interval (vs. long erect setae, weakly longer than half the width of one interval) and rostrum as long as wide, parallel-sided (vs. wider than long, tapered anteriad).
