Leptostilbus rutilans Casey 1916: 72 Review of the species described in Leptostilbus Casey in North America (Coleoptera: Phalacridae: Xanthocomus Guillebeau) Gimmel, Matthew L. Insecta Mundi 2011 2011-09-02 2011 188 1 8 (Casey, 1916) Gimmel 2011 Casey 1916 [192,678,1826,1851] Insecta Phalacridae Xanthocomus GBIF Animalia Coleoptera 3 2 Arthropoda species rutilans comb. nov.      Leptostilbus rutilans Casey 1916: 72.   Diagnosis. May be distinguished from  X. concinnusby the presence of obvious punctures in the (especially second and third) elytral intervals, especially at about midpoint of elytra ( Fig. 3). The male hind tibiae are also modified such that the apical spurs are stouter and directed more medially. The aedeagus provides the most reliable characters for separation ( Fig. 5, 6), including the fused parameres (movable apical portion of tegmen) without a median cleft, and the apex of the penis not acutely pointed medially. The main character presented by Casey to separate the two species, namely the extent of the stiff setae at the apex of the prosternal process, is subject to variation due to abrasion.   Type material.  Eight syntypesin USNM, lectotypehere designated in order to stabilize the species and generic names, point-mounted male with genitalia removed and mounted in DMHF on an acetate card on the same pin, “Brownsville \ Texas\ Wickham // CASEY \ bequest \ 1925 // rutilans 7 \ PARATYPEUSNM \ 48982 [species name and numbers handwritten] [red label] // LECTOTYPE\ Leptostilbus\ rutilans Casey\ des. M.L.
