Euphoria candezei Species-Group

(Appendix 3: Plate 2j–r)

The species in this group are distinguished by the strongly raised clypeal sides, depressed frons, impunctate scutellum, strongly to moderately emarginate base of the pronotum, mesometasternal process extending anteriorly well beyond the mesocoxae, metatarsi sexually dimorphic in length (shorter than metatibiae and compressed in females, slightly shorter or longer in males), abdomen of males without a deep, longitudinal depression, and distinct form of the parameres. The lateral margins of the pronotum are sexually dimorphic in this group, being more evident in some species (i. e., Euphoria westermanni (Gory and Percheron)) and vague or absent in some specimens at times. The lateral pronotal margins in the females are frequently angulate, appearing subparallel at the base. Males have the lateral pronotal margins more evenly rounded, appearing convergent at the base.

Composition. Three species are included: E. candezei Janson, E. lesueuri (Gory and Percheron), and E. westermanni (Gory and Percheron) .
