Dendropaemon (Crassipaemon) Cupello and Génier , new subgenus

Etymology. From the Latin crassus, meaning “thick, fat, stout” ( Brown 1956), and the Greek suffix paemon, which makes reference to the genus name Dendropaemon (see Génier and Arnaud 2016 for a detailed discussion on the etymology of this latter name). The chosen name makes reference to the body’ s overall aspect of the species included in this subgenus, which are more robust than most of the other Dendropaemon specie. Gender masculine.

Type Species. Dendropaemon amyntas Lacordaire, 1856 , here designated.

Diagnosis. Size moderate to large. Habitus rectangular in dorsal view, parallel-sided; with metallic sheen on head, pronotum, and elytra. Body moderately compressed dorsoventrally. Clypeal edge emarginated or not on external side of each clypeal tooth; clypeal teeth triangular. Pronotum with moderate punctures on disc, punctures larger and more or less confluent and forming rugulae anteriorly; anterior margin flat lateral to eyes; lateral fossae more or less oval, simple. Elytral base lacking margin. Meso- and metatarsi slightly dissimilar in shape, three-segmented, first segment as long as to twice as long as wide at apex, last segment spiniform, lacking setae apically.

Species Composition. Dendropaemon (Crassipaemon) amyntas Lacordaire, 1856 , D. (C.) attalus Génier and Arnaud, 2016, D. (C.) lydiae Génier and Arnaud, 2016, and D. (C.) morettoi Génier and Arnaud, 2016.

Distribution. South America, known from Colombia, French Guiana, and Brazil ( Génier and Arnaud 2016).

Finally, clarification is needed on another nomenclatural issue addressed in Génier and Arnaud (2016). As correctly stated, Agassiz (1846) unjustifiably emended the name Dendropaemon to Dendropemon . Therefore, being an unjustified emendation, and following Article 33.2.3 of the Code, Dendropemon Agassiz is an available name and a junior objective synonym of Dendropaemon Perty , a fact overlooked by Génier and Arnaud (2016). Additionally, Dendropemon Agassiz is also a junior homonym of Dendropemon Schönherr, 1939 , a genus of Anthribidae (Coleoptera) . Although Dendropemon Agassiz is an available name different from Dendropaemon Perty , new specific names proposed in combination with the former should not be cited with author and year in parentheses when in combination with the latter, according to Code’ s Article 51.3.1. Although commonly used during the 19 th and the first half of the 20 th century, the Dendropemon spelling was last applied by Blackwelder (1944). Since then, all works have correctly cited Perty’ s original spelling of Dendropaemon .
