Paratypes (86). Same data as holotype (45, USNM); same data as holotype except 25Feb1985 (36, USNM; 5, MLGC); all with label added “ PARATYPE \ Steinerlitrus \ warreni Gimmel \ det. M.L. Gimmel 2011 [yellow label]” .

Description. Total length 2.0– 2.2 mm. Color dark brown, often with nebulous lighter areas along base of elytra, around elytral suture in basal half, and along the lateral margins of the pronotum and elytra; appendages testaceous. Antenna slightly longer than width of head capsule; antennal club about as long as funicle; antennomere XI markedly turbinate, slightly shorter than IX and X combined ( Fig. 36b ). Head punctation extremely fine and dense. Pronotal punctation similar to that of head; posterior margin not bordered; with weak scutellar lobe; hind angles obtuse. Elytron devoid of microsculpture, with quite weak diffraction grating; sutural stria weak but evident in apical 1/3, additional striae indicated by rows of weak punctures, striae not impressed, intervals with row of punctures similar in size to those of striae; elytral posterior angle sharp, acute. Prosternal process setose medially. Metaventrite densely setose medially. Metatarsomere I about half as long as II; metatarsomeres I and II together about as long as remainder of tarsus ( Fig. 36d ).

Tegmen of aedeagus with fused parameres partially set off from basal piece ( Fig. 36h ). Penis narrowed in apical 1/5 ( Fig. 36h ). Spermatheca as illustrated ( Fig. 36j ).

Diagnosis. This species may be recognized by the characters given in the generic diagnosis.

Etymology. The specific epithet is a further monument to Warren E. Steiner, Jr., collector of the holotype and the entire type series. The epithet is a noun in the genitive case.
