Melanepyris Kieffer, 1913 was proposed to accommodate a single species of Epyris Westwood, 1832, E. imicola Kieffer, 1913, mainly based on the absence of the posterior propodeal carina. Today, Melanepyris includes only two nominal species. The type-material of these species has been considered lost since their original description. In this study, the single known adult male (holotype) of Melanepyris asiaticus Kieffer, 1922 from the Philippines has been rediscovered, redescribed and illustrated. Melanepyris asiaticus is transferred to Epyris Westwood due to the following features: scutellar groove absent, well separated scutellar pits and lower mesopleural fovea large and with undefined upper margin. We checked the original description of M. imicola and concluded that it also fits the definition of Epyris perfectly, except for the (described) absence of a posterior carina. However, the thickness of the posterior carina of the propodeal disc varies within species of different Epyrinae genera. The diagnostic characters used by Kieffer to create Melanepyris and other genera from Epyris are briefly discussed. Melanepyris is proposed as a new junior synonym of Epyris, with the transfer of M. imicola to Epyris.

Observou-se a viabilidade dos produtos à base de amido extrusado, que são usados como protetores de embalagens frágeis, como recurso alimentar para espécies-praga de grãos armazenados: Cryptolestes ferrugineus (Stephens), Lasioderma serricorne (Fabr.), Oryzaephilus surinamensis (L.), Sitophilus oryzae (L.), Tribolium castaneum (Herbst) (Coleoptera) e Plodia interpunctella (Hübner) (Lepidoptera). Cryptolestes ferrugineus, L. serricorne e T. castaneum foram encontrados nesses produtos, usando-os como alimento e abrigo. Sob experimentação, O. surinamensis, S. oryzae e P. interpunctella se desenvolveram, alimentando-se também desse recurso. Desta forma, registra-se a viabilidade dos flocos de amido extrusado como potencial veículo disseminador de pragas.

We observed the viability of extruded starch products used as impact protector for fragile packing as a food source of the following stored grains pests: Cryptolestes ferrugineus (Stephens), Lasioderma serricorne (Fabr.), Oryzaephilus surinamensis (L.), Sitophilus oryzae (L.), Tribolium castaneum (Herbst) (Coleoptera) and Plodia interpunctella (Hübner) (Lepidoptera). Cryptolestes ferrugineus, L. serricorne and T. castaneum were found in these products, which are used by them as shelter and food. Under experimentation, we observed the development of O. surinamensis, S. oryzae and P. interpunctella feeding on this food source. Thus, it is recorded the viability of such material to be a potential dispersal vehicle to spread insect pests.
