RESUMO
The species of the genus Copelatus Erichson, 1832 occurring in the Dominican Republic are reviewed. Five species are recorded, with recent collecting data provided for four of them. Copelatus martini sp. nov., a member of the consors species group, is described and illustrated. It is compared to the apparently similar species C. guadelupensis Legros, 1948 based on morphological characters and on partial sequences of the CO1 gene. Interesting cases of intraspecific variability in the number of elytral dorsal striae in C. martini sp. nov. and C. vitraci are discussed in the light of the traditional taxo-nomic importance of this character for species group delimitation in Copelatus. Copelatus caelatipennis Aubé, 1838 and C. vitraci Legros, 1948 are recorded for the first time from the Dominican Republic (and therefore also from Hispaniola Island). The remaining species are C. posticatus (Fabricius, 1801), and C. insolitus Chevrolat, 1863 (for the latter, pre-sence in Hispaniola is doubtful and requires confirmation). Finally, C. guadelupensis is recorded from Puerto Rico for the first time, and a checklist of the Copelatus species of the Antilles is appended.

Preimaginal stages of the six species of Hydraenidae presently known from Cuba were obtained by rearing adults in the laboratory. Eggs of Hydraena perkinsi Spangler, 1980, H. decui Spangler, 1980 and H. franklyni Deler-Hernández & Delgado, 2012 are described and illustrated for the first time. The first instar larva of Gymnochthebius fossatus (LeConte, 1855) is redescribed, adding some new remarkable morphological characters including what could be the first abdominal egg-burster reported for this family. All larval instars of H. perkinsi, H. guadelupensis Orchymont, 1923 and Ochthebius attritus LeConte, 1878 are described and illustrated for the first time, with a special emphasis on their chaetotaxy. The second instar larva of G. fossatus along with first and third instar larvae of H. decui and H. franklyni are also studied for the first time. The pupal morphology and vestiture of a species belonging to the genus Hydraena are described for the first time, based on the pupa of H. perkinsi. Biological notes for several preimaginal stages of the studied species are also given.

Two new species of the genus Hydraena Kugelann, 1794 collected from hygropetric habitats in eastern Cuba are described: Hydraena (Hydraenopsis) blancae sp. nov. from the Nipe-Sagua-Baracoa mountain range, and Hydraena (Hydraenopsis) matthiasi sp. nov. from the Sierra Maestra mountain range. Both species, especially the latter, are closely related to Hydraena (Hydraenopsis) franklyni Deler-Hernández & Delgado, 2012. Diagnostic characters for both new species are provided and illustrated; habitat information and distributional data are also included. An updated key to Cuban species of Hydraena is provided. With this study, the number of species of Hydraena known from Cuba raises to six.

The Cuban fauna of the genus Berosus Leach, 1817 is reviewed based on newly collected material as well as historical and type specimens. Nine species are recognized, including three recorded from Cuba for the first time: Berosus infuscatus LeConte, 1855, Berosus interstitialis Knisch, 1924 (= Berosus stribalus Orchymont, 1946 syn. n.) and Berosus metalliceps Sharp, 1882. Only one of the nine Cuban species, Berosus chevrolati, remains endemic to Cuba, as two other species previously considered as endemic to Cuba are recorded from elsewhere: Berosus quadridens from Mexico and Central America and Berosus trilobus from the Dominican Republic. Notes on biology and Cuban distribution are provided for all nine species. Berosus quadridens Chevrolat, 1863, stat. restit. is removed from synonym with Berosus truncatipennis and considered a valid species.
ResumenLa fauna cubana de Berosus Leach, 1817 es revisada a partir de nuevo material colectado así, como de material tipo e histórico. Se reconocen un total de nueve especies, incluyendo tres nuevos registros: Berosus infuscatus LeConte, 1855, Berosus interstitialis Knisch, 1924 (= Berosus stribalus Orchymont, 1946, syn. n.) y B metalliceps Sharp, 1882. Solo una de las nueve especies cubanas, Berosus chevrolati, permanece como endémica, las otras dos especies originalmente consideradas como endémicas han sido registradas fuera de Cuba: Berosus quadridens presente en México y América Central y Berosus trilobus en República Dominicana. Se ofrecen datos sobre la biología y la distribución de todas las especies cubanas. Berosus quadridens Chevrolat, 1863, stat. restit. es destituida como sinónimo de Berosus truncatipennis y considerada como una especie válida.
RESUMO
Three species of Parandrinae are recognized from Cuba, all belong to Birandra (Yvesandra) Santos-Silva & Shute, 2009: B. (Y.) cubaecola (Chevrolat, 1862); B. (Y.) cribrata (Thomson, 1861); and B. (Y.) latreillei Santos-Silva & Shute, 2009. The latter, confused with the former by Zayas (1957, 1975) is confirmed as a common species on the island. Birandra (Y.) cubaecola is excluded from the fauna of Puerto Rico; B. (Y.) cribrata is also excluded from Puerto Rico as well as Hispaniola.
Três espécies de Parandrinae são reconhecidas em Cuba, todas pertencentes ao subgênero Birandra (Yvesandra) Santos-Silva & Shute, 2009: B. (Y.) cubaecola (Chevrolat, 1862); B. (Y.) cribrata (Thomson, 1861); e B. (Y.) latreille Santos-Silva & Shute, 2009. Esta última, confundida por Zayas (1957, 1975), é confirmada como espécie comum na ilha. Birandra (Y.) cubaecola é excluída da fauna de Porto Rico; B. (Y.) cribrata também é excluída da fauna de Porto Rico assim como da ilha de Espanhola (Haiti e República Dominicana).
