Overwintering Melanotus, photographed by Stephen Cresswell.

Belongs within: Elateridae.

The Melanotini are a group of click beetles with prominently pectinate claws. Species in the tribe can be difficult to distinguish; the majority are placed in the genus Melanotus (Stibick 1979).

Characters (from Stibick 1979, as Melanotinae): Adult: Head capsule oval, deflexed, mouthparts inferior, frons ridged above and between antennae (may be obsolete in middle); prosternum normally arcuate anteriorly; scutellum various, never cordate, may be slightly excavate anteriorly; mesocoxae open to mesepimeron but closed to mesepisternum; meso- and metasternum distinct, joined by a definite suture; tarsi simple, without pads, but rarely 3rd segment broadened to receive 4th; claws prominently pectinate and without basal setae. Larva: Nasule present, galea of 2 segments, postmentum subrectangular; laterotergite incompletely separated from mediotergite at most; spiracle generally well developed, embedded in mediotergite; 9th abdominal segment flattened in caudal half, no prongs or caudal notch but platelike and scalloped.
