Eupogonius flavocinctus Bates, 1872 ( Figs. 1 A-1B)

Eupogonius flavocinctus Bates, 1872: 235 . Remarks: Eupogonius flavocinctus was described based on a single specimen from Nicaragua. Chemsak et al. (1992) recorded the species from Costa Rica. The material examined allows expanding the geographical distribution of this species considerable toward north. Therefore, it probably also occurs in intermediate countries ( Honduras, El Salvador, Guatemala, and Belize).

According to Hovore (1989) on Eupogonius cryptus Hovore, 1989 :“This species is very similar in appearance to E. flavocinctus Bates ( Fig. 1A ), and the two taxa have been placed as a single species in most collections. Eupogonius cryptus differs immediately by its paler pubescent pattern (yellowish-orange in E. flavocinctus ), presence of submarginal elytral vittae, denser appressed body pubescence, slightly wider pronotum, and denser, more regular dorsal punctation. Also, the basal one-third of the fourth antennal segment, in E. flavocinctus is constricted, testaceus, sparsely pubescent,distinctly pale annulate.”This information encompasses problems:1.The color of the pubescent bands is variable in E. flavocinctus . In fact, the pubescent bands in the holotype are distinctly paler (see photographs on Bezark, 2021), and the allotype of E.cryptus (see photographs on Bezark,2021) has the pubescent bands distinctly yellower. Furthermore, both pale and yellow pubescent bands may be present in the same specimen; 2. Although the pubescence on basal one-third of the antennomere IV is somewhat variable in E.flavocinctus , it is not as sparse as in the illustration presented by Hovore (1989),including in the holotype; 3.The color of the basal one-third (in fact,often basal half) of the antennomere IV is very variable and often, the antennomere is entirely dark; 4. The allotype of E. cryptus has the antennomere IV as described by Hovore (1989) to E. flavocinctus . Despite these contradictions, we are keeping E.cryptus as a different species.This is because according to Hovore (1989), the elytron in E. cryptus has four longitudinal pubescent bands, and all specimens of E. flavocinctus examined have three longitudinal pubescent bands. Even so, it is necessary to say that the holotype and allotype photographs do not allow us to see the “submarginal vitta extending from humerus to near apex” mentioned in the original description.
