Drymo Thomson 1864

Drymo Thomson, 1864 revalidated Figs 41–46 Drymo Thomson, 1864: 242. Remarks. The features indicated by Thomson (1864) separating Drymo from Eleutho are very variable in Eburiini: shape of the head, antennal length, shape of the base of the scape, length of antennomere XI, among others. Therefore, they need to be considered as specific features and not as generic features. However, this does not prevent the two genera from being treated here as distinct taxa, owing to the presence of other important features that were not mentioned by Thomson (1864) as differential. According to Botero and Monné (2018): “ The monophyly of Eburia (Eleutho) was recovered, with high support values, and supported by six homoplastic synapomorphies, some of them being exclusive among the Eburiini: the surface of the scape granulate (15: 1, shared only with Trachyderes succinctus), the apical margin of antennomere III with projection at outer side (22: 1), and the antennomeres IV – IX with a projection on the outer side (25: 1). ” Coeleburia pulverea Chevrolat, 1862 (currently, Eburia didymus (Olivier, 1800)), the type species of Drymo, also has the scape granulate but does not have the flagellomeres with apical projection. Furthermore, males of Drymo have the sides of the prothorax without a lateral tubercle, while they are present in males of Eleutho. Although this last feature is variable in Coeleburia (Eburia sensu auctorum), the antennomeres are distinctly carinate from IV in both sexes (not carinate in Eburia sensu auctorum). Therefore, we revalidate Drymo to include only one species: Drymo didymus (Olivier, 1800), comb. nov.:
