Dinothenarus capitatus

University of Alberta E.H. Strickland Entomological Museum

SeasonalityThe only D. capitatus specimen in the Strickland Museum was collected in June. IdentificationThe size of an adult D. capitatus ranges between 12.5 to 15mm (Downie and Arnett, 1996). The adult D. capitatus is quickly recognized by a densely punctate head with dark yellow color. The temples are almost straight behind the eye (Smetana and Davies, 2000). The color of the head contrasts with the dark brown pronotum and abdomen. The pronotum is covered with patches of yellow setae among the black setae (Downie and Arnett, 1996). The legs are mostly dark brown with some dark yellow area on dorsal side of femur and tibia. The antennae are slightly darker than the head. The densely punctate elytra are covered with widely scattered smooth spots with dark pubescent (Downie and Arnett, 1996). Abdominal terga (dorsal abdominal segment) 2-4 with H-shaped velvety spot at middle and segment 5-6 with gray pubescence (Downie and Arnett, 1996). The gray pubescence is also present on nearly all sternites (ventral abdominal segment). Tarsal formula 5-5-5 and 11 antenomeres with the last one transverse. The last segment of the labial palp is narrow and fusiliform (Downie and Arnett, 1996).
