Etymology.

The species is named for our friend and professional colleague Dr. David W. Langor, Canadian Forest Service, collaborator and supporter of many joint entomological projects. He contributed to the discovery and descriptions of many new species of aleocharine beetles in Canada, particularly in Newfoundland and Alberta.

Diagnosis.

Body narrowly subparallel (Fig. 49), length 2.2-2.5 mm, uniformly black; head, pronotum and elytra finely and densely punctate, punctures small; pubescence dense; integument moderately glossy, more so on abdomen, with meshed microsculpture (Fig. 49); antenna with articles V-X subquadrate to slightly transverse (Fig. 49); head about as wide as pronotum (Fig. 49); pronotum transverse, slightly narrower than elytra at base, with pubescence directed obliquely laterad from median line of disc and in basal part of median line directed anteriad and laterad, base of disc with small oval impression (Fig. 49); elytra at suture about as long as pronotum and slightly wider at base than pronotum (Fig. 49); abdomen subparallel. MALE. Tergite VIII truncate apically (Fig. 52); sternite VIII elongate and notched apically (Fig. 53). Median lobe of aedeagus with large broad bulbus and narrow triangular tubus in dorsal view, bulbus strongly sinuate laterally (Fig. 51), in lateral view tubus straight and slightly sinuate basally; crista apicalis of bulbus small (Fig. 50); internal sac structures as illustrated (Figs 50, 51). FEMALE. Tergite VIII truncate apically (Fig. 54); sternite VIII arcuate apically (Fig. 55); spermatheca with pitcher-shaped capsule bearing broad and deep apical invagination, stem broad, and coiled (Fig. 56).

Distribution.

This species is known only from SK.
