Diagnosis

Body length 6.3-6.5 mm. Body width 3.0-3.2 mm. Head basic color black. Antennae filiform, with thickened antennomeres 4-6, bi- or tricolored, antennomere 1 and 9-10 sulphur yellow, antennomeres 2-3 yellow, upper sides darkened, antennomeres 4-8 brussels brown, antennomere 11 dark apically. Maxillary palpi and labrum black or piceous.

Scutellum piceous or black. Elytra yellow, rufous or black, uniformly colored or testaceous, narrowly margined with black, or black, maculate with three sharp-edged sulphur yellow maculae on each elytron, sometimes divided into two parts. Elytral epipleura completely black, narrow interior edge is pale. Sutural angle of elytra round or obtuse-angled, punctation scattered, fine. Abdomen yellow. Tarsi and tibiae black or chestnut.

Remarks

The type of D. hogei in BMNH is a female. We studied the male in the MCZ collection bearing the label 'Playa Vicente, Mexico, Salle Coll.,' which is morphologically identical with the type. We treat it as the male of D. hogei. After study of additional material in the MCZ and USNM collections it was found that D. hogei is very variable species. We recognized at least four different color varietimorphs. The internal sac armament is the same in all of them.

 

Potential problems with identification

Diabrotica hogei Jacoby is very similar to D. h1n, D. panamensis Jacoby and D. olivieri Jacoby. They can be separated by the following features: the narrow interior edge on elytra epipleura is pale in D. hogei; but completely black in D. panamensis and completely yellow in D. olivieri; scutellum is black in D. hogei, but yellow in D. olivieri; the armament of the internal sac is quite different in all four species.
