Very similar in habitus to  L. clandestinus, although having the dorsal punctation slightly more apparent. The aedeagi of the two species are similar in shape ( Figs. 20, 21), but in  L. steinerithe aedeagus is longer, more sharply pointed apically, and in lateral view much less arcuate (almost straight for most of its length), and has the pair of long setae located more distally.   Description. Size: holotype(length/width, mm): body (length to elytral apices) 0.88/0.50; head width 0.35; pronotum 0.23/0.50; elytra 0.55/0.50; approximate height, lateral view 0.28. Dorsum brown to piceous, head and pronotum sometimes darker than elytra. Body form distinctively drop-shaped. Pronotum with disc shining, nonmicroreticulate, very sparsely finely punctulate, each puncture with very short adpressed seta; area posterior to eye (side view) with slightly larger punctures, each puncture with adpressed seta, longer than setae on disc. Elytra nonmicroreticulate or very weakly effacedly so, with punctures and setae similar to those on pronotum. Males with first three pro- and mesotarsal segments slightly enlarged, with adhesive setae. Labroclypeal suture arcuate in frontal view in both sexes. Labrum simple, similar in sexes. Lateral angle of elytral apices more widely rounded and apices more truncate in males than in females, sutural angle more acute in females.   Etymology.Named in honor of the collector, friend and colleague, Warren Steiner. 1697157768 1993-09-06 USNM W.
