Liodessus picinus sp. nov. is described from the Páramo de Sumapaz near Bogota D.C. at 3,500 m above sea level. The species can be distinguished from the other Colombian Liodessus species by its dark colora-tion, discontinuous habitus, shiny surface of the pronotum and elytron, presence of a distinct occipital line, distinct basal pronotal striae,...

We present a key to the three species of the genus Phelister Marseul, 1854 (Coleoptera, Histeridae), occurring in Cuba along with diagnoses and habitus drawings. All three species are newly recorded for the cadaveric fauna in Cuba. In addition, we address the taxonomic composition and distribution of the genus Phelister in the country. Phelister co...

We here describe Liodessus lacunaviridis sp. n. (Coleoptera: Dytiscidae, Bidessini), collected from small mossy puddles at the edge of the Laguna Verde, Boyaca, Colombia. Within Liodessus Guignot, 1939 the new species is well characterized by its darker coloration, more elongate oval habitus, and the shape of the median lobe in ventral view, which...

The diving beetle Rhantus blancasi Guignot, 1955 (Coleoptera, Dytiscidae, Colymbetinae) was until now only known from older reports from Pasco region, Peru. Here, we provide new distributional data from Cuzco and Junin regions, habitat information, and illustrations of diagnostic characters for the easy identification of the species.

Resumen: En Cuba está registrada la mayor riqueza de especies de la familia Dytiscidae de las Antillas. Sin embargo, no existe ningún trabajo recopilatorio que permita la identificación a nivel específico. El objetivo de este estudio fue la confección de claves dicotómicas ilustradas para las especies en estado adulto de la familia Dytiscidae de Cu...

We review the Peruvian Hydaticus Leach, 1817 (Coleoptera: Dytiscidae) and describe Hydaticus panguana sp. nov. from Huánuco Department. In the context of this work, we also provide new country records for several species: Hydaticus lateralis Laporte, 1835 (for Peru, Guyana, Venezuela, Suriname); H. xanthomelas (Brullé, 1837) (for Peru); H. subfasci...

The Colombian species of the diving beetle genus Liodessus Guignot, 1939 are revised. Liodessus bogotensis Guignot, 1953 is re-described. Three higher altitude species are new to science: Liodessus azufralis sp. n., L. quillacinga sp. n. and L. quimbaya sp. n. We also introduce two new subspecies, L. quillacinga cochaensis ssp. n. and L. quillacing...

Los macroinvertebrados dulceacuícolas incluyen a especies de moluscos, anélidos, artrópodos (mayoritariamente insectos), nemátodos y turbelarios que tienen en común una talla igual o superior a los 500 μm y que desarrollan al menos una parte de su ciclo de vida en un cuerpo de agua no marino. En Cuba se han realizado avances en el empleo de los mac...

Cuba has one of the richest diving beetles species diversity in the Caribbean islands. However, Cuban Dytiscidae remain scarcely studied, and there is need to identify those species and habitats that urgently require effective conservation actions. Here we aim to identify the threatened taxa of the family Dytiscidae in Cuba according to their degre...

Platambus americanus (AUBÉ, 1838) is recorded for the first time for El Salvador (San José del Sacare, Chalatenango Department), which marks the southern most record of the genus in the New World. Altogether 66 species of the genus are known worldwide, with two species in Central America.

La presente obra ofrece un compendio de métodos para el inventario y el monitoreo de diferentes grupos de la biota terrestre en Cuba. Realizada con la colaboración de 71 especialistas, fue escrita fundamentalmente para estudiantes, biólogos de campo, profesionales y técnicos de la conservación, que desarrollen trabajos relacionados con las ciencias...

We describe Copelatus adelbert sp. n., the first member of the Copelatus hydroporoides group from the Australian Region. The species is endemic to the Adelbert Range in Papua New Guinea. In addition to lacking striae on elytra (character of the O. hydroporoides group), Copelatus adelbert sp. n. is very characteristic due to its colouration, with br...

This paper deals with the taxonomic composition,

The third instar of the Antilles endemic species Pachydrus obniger (CHEVROLAT, 1863) (Coleoptera: Dytiscidae) is described and illustrated. This species has turned out as very similar to P. globosus (AUBÉ, 1838) in terms of larval morphology and it is postulated that P. obniger might represent a junior synonym of P. globosus.
