Diagnosis

Canthidium feeri sp. nov. differs from other species of the group by the distinct anterior pronotal punctation, apparently lacking punctures on the centre of the disc.

Etymology

Named for François Feer, French scarabaeidologist, working at the Muséum national d’Histoire naturelle (Paris, France) who collected half of the type series.

Type locality

Description (holotype)

MEASUREMENTS. Length: 9 mm.

HEAD. Surface dense and distinctly punctated. Frontoclypeal carina rectangular and with length less than three-fourths of interocular distance.

PRONOTUM. With anterior carina and lobes not evident, positioned just behind anterior border and separated from border by distance less than the border width; anterior region of disc punctated, posterior region with indefinite punctation.

HYPOMERON. Hypomeral carina complete.

METAVENTRITE. With simple and shallow punctation, laterobasal and lateral region with microsculpture finely strigulate.

MESEPIMERON AND MESEPISTERNUM. With shallow punctation and microsculpture finely strigulate.

HIND LEG. Metafemora with a carina along posterior edge, anterior edge with setal fringe, surface with fine punctation. Metatibiae elongated and gradually dilated towards the apex; external margin serrated.

AEDEAGUS. Parameres, in lateral view, dorsally with angulation on basal third.

Variation and sexual dimorphism

Total length ranging from 9.00 to 10.67 mm. Some males present a small tooth in the upper ventral part of their metatibiae and some have a protuberance on their basal half. Males with ventrite VI wider

medially, female ventrite VI with the same length throughout. Males also have protibial spur flattened, while in females the protibial spur is narrowed and pointed.

Geographical distribution

All the specimens examined for this work were collected in French Guiana, which is located in the Boreal Brazilian dominion.
