Agrypnus argillaceus, from here.

Belongs within: Agrypninae.

The Agrypnini are a large group of click beetles distinguished by having deep grooves on the prosternal sutures that the antennae can lay in, and an undivided mesosternum and mesepisternum (Stibick 1979). The genera Lanelater and Agrypnus are each found worldwide except in South America; species of Agrypnus have a vestiture of scales, at least in part, whereas Lanelater lack scales (Calder 1996).

Characters (from Stibick 1979): Prosternal sutures with deep grooves for reception of antennae, rarely grooved posteriorly for reception of anterior tarsi; frontal carina absent, vague or more or less present above to variously developed between antennae, frons more or less concave, mouthparts inferior; prosternal lobes normally arcuate or even prominent, prosternum simple, without cross or transverse sutures, propleuron and metasternum may be either grooved for tarsae or antennae or not; mesosternum and mesepisternum simple, not divided by cross sutures, meso- and metasternum with distinct suture or suture indistinct or absent; scutellum shield-shaped, never cordate; tarsi various; claws with seta(e) at base (rarely absent).
