Leiodes longitarsis species group

Species included. Leiodes longitarsis Baranowski, 1993

Diagnosis. Elytra unicolor, with sparsely arranged large punctures between rows of punctures (Fig. 36D); mesoventrite without distinct excavation between median carina and transverse carina (Fig. 36E); protarsi showing sexual dimorphism, tarsomeres 2–4 of male protarsi expanded (Fig. 37A); mesotibiae without sexual dimorphism, simply square at interoapical corner; dorsal posteroapical projection of metafemora small and not showing sexual dimorphism (Figs. 37G, 37H); pubescence of metaventrite sexually dimorphic (Figs. 36F, 36G); aedeagus thick, with some large sclerites in inner sac (Fig. 38A); male abdominal sternite 8 strongly curved (Fig. 38C); female abdominal sternite 8 with a spiculum ventrale at central point of anterior margin (Fig. 38D).

Note. Leiodes longitarsis was described from North America and is a common species in the Holarctic Region. The L. longitarsis species group was established for this single species by BARANOWSKI (1993), who distinguished it from related species groups by male sexual characters on the legs, and by the shape of the aedeagus. An especially notable morphological feature of this group are the male metatarsi which are clearly longer than those of females (Figs. 37C, 37D).
