Review of the species described in Leptostilbus Casey in North America (Coleoptera: Phalacridae: Xanthocomus Guillebeau) Author Gimmel, Matthew L. text Insecta Mundi 2011 2011-09-02 2011 188 1 8 journal article 10.5281/zenodo.5161173 1942-1354 5161173 Xanthocomus concinnus ( Casey, 1916 ) , comb. nov. Leptostilbus concinnus Casey 1916: 72 . Diagnosis . May be distinguished from X. rutilans by the absence of obvious punctures in the elytral intervals ( Fig. 4 ). The male hind tibiae are similar to those of the female, and the apical spurs are directed more apically. The aedeagus provides the most reliable characters for separation ( Fig. 7, 8 ), including the fused parameres (movable apical portion of tegmen) with a broad median cleft, and the apex of the penis acutely pointed medially. Type material . Three syntypes in USNM, lectotype here designated in order to stabilize the species name, point-mounted male with genitalia removed and mounted in DMHF on an acetate card on the same pin, “·Miss [=Vicksburg, Mississippi ] // CASEY \ bequest \ 1925 // TYPE USNM \ 48984 [number handwritten] [red label] // concinnus \ Csy. // LECTOTYPE \ Leptostilbus \ concinnus Casey \ des. M.L. Gimmel 2010 [red label]” ( Fig. 2 ) ( USNM ). Paralectotypes (2): with labels, one female with genitalia dissected, “·Miss // CASEY \ bequest \ 1925 // concinnus [numeral corresponding to paratype number] \ PARATYPE USNM \ 48984 [numbers handwritten] [red label] // PARALECTOTYPE \ Leptostilbus \ concinnus Casey \ det.
