Abstract

Descriptions and illustrations of the triungulin, 5th instar, and prepupal larval forms for Nematodes penetrans (LeConte, 1852) (Coleoptera: Eucnemidae: Macraulacinae: Nematodini) are given. The descriptions are based on triungulins collected in a plastic vial as well as 5th instars and prepupal larval stages collected from hard sections of sugar maple (Acer saccharum Marshall; Aceraceae) logs and limbs. Adults were reared from those pieces placed in plastic bags. Biological information is provided, based on literature search and personal observations. Comparative studies between larvae of N. penetrans and the European species, Nematodes filum (Fabricius, 1801) along with other Nearctic larval forms are briefly discussed. This discovery represents the first larval description for the genus in the Nearctic region.
