Diagnosis.

This species is similar in appearance to L. washingtoni but differs in having elongate antennomeres. Males are otherwise difficult to tell apart, even in the primary and secondary sexual characters. Lathrobium leconteanum has four spines on the internal sac of the aedeagus whereas L. washingtoni has two. Females are more easily differentiated because L. leconteanum has an undivided tergite IX and L. washingtoni has tergite IX fully divided.

Description.

Body length 7 mm; body coloration dark red, appendages lighter. Gular sutures parallel, widely separate; antennomeres V-VII longer than wide. Elytra 1.2 × longer than pronotum. Females with paraprocts undivided, apices 1.3 × as long as basal portion; sternite VIII conical with small apical notch. Genitalia as in Fig. 44.

Distribution.
