Background: Although whole-genome sequencing (WGS) is the preferred genotyping method for most genomic analyses, limitations are often experienced when studying genomes characterized by a high percentage of repetitive elements, high linkage, and recombination deserts. The Asian tiger mosquito (Aedes albopictus), for example, has a genome comprising up to 72% repetitive elements, and therefore we set out to develop a single-nucleotide polymorphism (SNP) chip to be more cost-effective. Aedes albopictus is an invasive species originating from Southeast Asia that has recently spread around the world and is a vector for many human diseases.

Background: The worldwide genus Anopheles Meigen, 1918 is the only genus containing species evolved as vectors of human and simian malaria. Morbidity and mortality caused by Plasmodium Marchiafava & Celli, 1885 is tremendous, which has made these parasites and their vectors the objects of intense research aimed at mosquito identification, malaria control and elimination. DNA tools make the identification of Anopheles species both easier and more difficult.

Background: Accurate species identification of South American anophelines using morphological characters of the fourth-instar larva is problematic, because of the lack of up-to-date identification keys. In addition, taxonomic studies, employing scanning electron microscopy of the eggs and DNA sequence data, have uncovered multiple complexes of morphologically similar species, and resulted in the resurrection of other species from synonymy, mainly in the subgenus Nyssorhynchus. Consequently, the identification keys urgently need to be updated to provide accurate morphological tools to identify fourth-instar larvae of all valid species and species complexes.

Background: Morphological identification of adult females of described species of the genus Anopheles Meigen, 1818 in South America is problematic, but necessary due to their differing roles in the transmission of human malaria. The increase in the number of species complexes uncovered by molecular taxonomy challenges accurate identification using morphology. In addition, the majority of newly discovered species have not been formally described and in some cases the identities of the nominotypical species of species complexes have not been resolved.

Background: Accurate identification of the species of Anopheles Meigen, 1818 requires careful examination of all life stages. However, morphological characters, especially those of the females and fourth-instar larvae, show some degree of polymorphism and overlap among members of species complexes, and sometimes even within progenies. Characters of the male genitalia are structural and allow accurate identification of the majority of species, excluding only those in the Albitarsis Complex.

Lachesilla is the most species-rich psocid genus, with 341 species grouped into 19 species groups (with at least 100 undescribed species), plus an additional undescribed species group. We present the first phylogenetic analysis of Lachesilla and a discussion on the relationships of sister genera of the subfamily Lachesillinae. We codified a matrix of 60 morphological characters (16 multistate and 44 binary) formed by 44 terminals: 37 ingroup species and seven outgroup species.

The fragmentation of DNA in historical specimens is very common, so obtaining sequences that allow molecular identification and the study of diversity is quite challenging. In this study, we used preserved and fresh specimens of the fruit fly genus , a genus of economic impact of fruit crops of the Neotropic. From these specimens, we evaluated: (1) the success PCR amplification rates of mini-barcodes fragments of the subunit I (COI) gene, and (2) the usefulness of mini-barcodes in the reconstruction of haplotypes for the identification of species and the diversity analysis.

Upon examination of ptiloneurid specimens recently collected in forests of natural areas and Natural National Parks in Colombia, ten males and seven females were found that represent five species of an undescribed ptiloneurid genus. It differs from the other genera in the family by characters of the wings, hypandrium, phallosome, epiproct, female gonapophyses, and sternum IX. An identification key to the males of the genera of Ptiloneuridae, and a key to the species of the new genus are presented.
