- A new species of Opatrinus (Coleoptera: Pedinini: Tenebrionidae) from Cuba (1994)
- A new species of an endemic tenebrionid beetle, Opatrinus armasi, is described from the environs of San Antonio de los Banos, Havana Province. The new species is found living syntopically in this area with the more widespread 0. pullus. Comparisons with various populations of this latter species are made. Photographs of the beetles, drawing of pronotum, as well as males genitalia of both species are given.
- Variability of Zophobas rugipes Kirsch (Coleoptera: Tenebrionidae: Tenebrioninii) in Cuba (1994)
- The blind click-beetles are the larger tenebrionids of Cuba. In our territory there are two species described, Zophbas rugipes Kirsch with a wide distribution in other West Indies, Central and South America, and Z. cubanus Marcuzzi, endemic to Cuba. Other authors had exposed the variability of Z. rugipes. We have compared all the available material from Cuban collections and have reached the conclusion that the diagnostic characters exposed for z. cubanus, based on a small series, are not valid. Therefore, we consider this taxon as an individual variation of Z. rugipes, and synonymize Z. cubanus under Z. rugipes.
