Cinco novas espécies de Cerambycidae (Insecta: Coleoptera) da Região Neotropical e novos registros

New species are described: Tessaropa elongata sp. nov. from Brazil (Rondônia) has long elytra, a character that distinguishes it from the remaining species with short elytra; Hexoplon immaculatum sp. nov. from Ecuador (Pichincha) is characterized by the red-orange general color and black legs. Eburodacrys inaequalis sp. nov. from Bolivia (Santa Cruz) has elytral apices and same-color femora that cause it to be similar to E. ayri Martins & Galileo, 2006 and E. silviamariae Martins & Galileo, 2006, yet it differs from either species in the black lateral spines and dorsal tubercles of pronotum and the elongate eburneuos maculae of the elytra. Coleomethia bezarki sp. nov. (Costa Rica, Guanacaste) differs from C. australis Hovore, 1987 by male pronotum without rugosities, peduculate metafemora and metatibiae entirely pubescent. Bisaltes (B.) petilus sp. nov. (Costa Rica, Guanacaste, Alajuela) is separated from B. (B.)buquetii Thomson, 1868 and B. (B.) fuchsi Breuning, 1971 by the more slender body appearance, the absence of dark belts on pronotum, and the absence of circular macula in the anterior third of elytra. Notes and new records are provided for: Tetraibion concolor Martins, 2006 (Bolivia: La Paz); Gnomidolon ornaticolle Martins, 1960 (Panama: Colón); Mephritus apicatus (Linsley, 1935) (Brazil: Rondônia).

Random amplified polymorphic DNA (RAPD) analysis of Lutzomyia longipalpis laboratory populations

The phlebotomine sand fly Lutzomyia longipalpis has been incriminated as a vector of American visceral leishmaniasis, caused by Leishmania chagasi. However, some evidence has been accumulated suggesting that it may exist in nature not as a single but as a species complex. Our goal was to compare four laboratory reference populations of L. longipalpis from distinct geographic regions at the molecular level by RAPD-PCR. We screened genomic DNA for polymorphic sites by PCR amplification with decamer single primers of arbitrary nucleotide sequences. One primer distinguished one population (Marajó Island, Pará State, Brazil) from the other three (Lapinha Cave, Minas Gerais State, Brazil; Melgar, Tolima Department, Colombia and Liberia, Guanacaste Province, Costa Rica). The population-specific and the conserved RAPD-PCR amplified fragments were cloned and shown to differ only in number of internal repeats.

Neopolystoma fentoni n. sp. (Monogenea: Polystomatidae) a parasite of the conjunctival sac of freshwater turtles in Costa Rica

Neopolystoma fentoni n. sp. is described from the conjunctival sac of Kinosternon leucostomum (Duméril, Bibron, and Duméril 1851) and Rhinoclemmys pulcherrima (Gray 1855) from the Guanacaste Conservation Area in Costa Rica. The new species differs from all other species of Neopolystoma, except N. elizabethae Platt 2000 in possessing a circle of eight genital spines that are recurved and possess a crescent-shaped base. N. fentoni n. sp. differs from N. elizabethae in lacking cecal diverticula and in a number of morphometric criteria.
