Tasmosalpingus Lea, 1919

Tasmosalpingus Lea, 1919: 743 . Type species: Tasmosalpingus quadrispilotus Lea, 1919 , by original designation.

Diagnosis. Tasmosalpingidae can be easily recognized from the superficially similar Salpingidae in having two pairs of setose concavities placed on the posterior corners of the pronotum and on the humeral areas of elytra ( Figs 2D, 2F , 4D, 4F ), the tarsal formula 5-5- 4 in male and 5-5- 5 in female. Tasmosalpingus can also be distinguished from the other families within Cucujoidea by the combination of the following characters: antenna with 11 antennomeres, with a club of 3 antennomeres ( Figs 2E , 4E ); antennal insertions exposed from above ( Figs 2A , 4A ); procoxal cavities slightly transverse, internally closed and widely open externally ( Figs 2C , 4C ); protrochantins exposed; prosternal process broad, apically emarginate; notosternal suture complete; scutellar shield distinctly transverse; epipleuron of elytra incomplete, sutural flanges slightly widened apically; mesocoxal cavities widely separated, laterally open to mesepimeron, mesotrochantins exposed; metaventrite without discrimen ( Figs 2G , 4G ); abdomen with 5 freely articulated ventrites, ventrite 1 only slightly longer than the second ventrite; male genitalia with tegmen ring-shaped, narrowly rounded at base; parameres small and articulated to tegmen, partly fused to separated; penis parallel-sided anteriorly, with a pair of slender basal struts, flagellum present and long ( Figs 2M , 4M ); ovipositor moderately elongated and membranous; styli well-developed, anterolaterally attached to gonocoxites.
