Lasconotus vegrandis
Horn, 1885
Lasconotus vegrandis is a of in the , first described by George Henry Horn in 1885. It belongs to a characterized by compact, cylindrical body forms adapted for life under bark. The species has been documented in western North America, with records from British Columbia. Like other members of its family, it is presumed to inhabit dead or decaying wood, though specific ecological details remain poorly documented.

Identification
Members of Lasconotus can be distinguished from other zopherid by their strongly cylindrical body form, with that are parallel-sided and often possess distinct surface sculpturing. L. vegrandis is among the smaller in the genus; the specific epithet "vegrandis" (Latin: "somewhat small") refers to its reduced size relative to . Positive identification to species level requires examination of male or comparison with , as external morphological differences between Lasconotus species are subtle.

Similar Taxa
- Lasconotus subcostulatusOverlapping distribution in western North America; similar cylindrical form but generally larger and with more pronounced elytral costulae (ridges). L. vegrandis is distinguished by its smaller size and relatively smoother elytral surface.
- Other Zopheridae (e.g., Pycnomerus, Orthocis)These share the habitus but differ in antennal structure, tarsal formula, and body proportions. Lasconotus have distinctly clubbed with compact, rounded .
