Diagnostic Characteristics

Eleven species of Uranotaenia, one belonging to the subgenus Pseudoficalbia and ten to the subgenus Uranotaenia, have been recorded in Mexico. In general, two species are commonly recorded in urban areas by the vector surveillance programs, but the other species are rarely collected as they occupy habitats in non-anthropized environments, and for that reason they remain poorly known. Some of the species recorded in Mexico have not been described in the pupal stage and other developmental stages have only been partially described, making their recognition difficult. One of these species is Uranotaenia (Uranotaenia) coatzacoalcos Dyar & Knab, as a complete description of its larval chaetotaxy is not available, and the pupa has not been described. In this report, we provide a complete morphological description of the fourth-instar larva, the first description of the pupa, and a review of the female and male diagnostic characteristics useful for recognition of the species. We also provide keys in English and Spanish for the recognition of the larvae, pupae, females, and male genitalia of the species of Uranotaenia recorded in Mexico.

The adult male and female of Psorophora (Psorophora) pallescens Edwards are redescribed. The pupa and fourth-instar larva are described for the first time. The male genitalia, pupa and fourth-instar larva are illustrated. Information on distribution, bionomics and taxonomy is also included. Psorophora pallescens adults differ from the other species of the subgenus in the coloration of the scutum and abdomen. The larva can be distinguished from Psorophora ciliata based on characters of the head, thorax and abdomen.

First Time

Sabethes (Sabethoides) glaucodaemon was described for the first time by Dyar & Shannon (1925) based on the adult female. Later, descriptions of the male genitalia and parts of the fourth-instar larva and pupa were published by other authors. No one has described the female genitalia or made a complete description of the larva and pupa. The aim of this study was to redescribe Sa. glaucodaemon in the adult stage, including the male and female genitalia, and the pupa and fourth-instar larva. All stages are illustrated. Distinctions from Sa. (Sbo.) tridentatus are discussed.

Diagnostic Characteristics

A neotype is designated for Anopheles (Nyssorhynchus) pictipennis (Philippi) and morphological redescriptions are provided for the adult male, male genitalia, fourth-instar larva and pupa. All specimens, including the neotype were collected in Río Mapocho, Santiago, Chile in 1945 / 1946, and were deposited in the Entomological Collection of Faculdade de Saúde Pública, Universidade de São Paulo (FSP-USP), Brazil. The neotype was previously invalidly designated the allotype of An. pictipennis by Lane and Neghme (1946). Illustrations are provided for diagnostic characteristics of the male genitalia, and larval stage.

Two New Species

Two new species of Sabethes subgenus Sabethinus (Diptera: Culicidae) from Costa Rica are formally named Sa. andreae and Sa. theresae. Descriptions consisting of differential and diagnostic morphological characters are provided for adults, male genitalia and fourth-instar larvae. The male genitalia and the fourth-instar larva and pupa of both species are illustrated. The species are compared with the four previously described species known to occur only in South America, i.e. Sa. idiogenes, Sa. intermedius, Sa. melanonymphe and Sa. xhyphydes. A new country record for Colombia is reported for Sa. xhyphydes and keys are provided to distinguish the adults and larvae of the six species.

Nei's Genetic Distance

Anopheles (Nyssorhynchus) deaneorum sp. n. is described from specimens collected in Guajará-Mirim, Rondônia state and Rio Branco, Acre state, Brazil, on human and animal baits, inside dwellings and from the progenies of engorged females. A detailed description of the shape of egg, external appearance of adult female and male, genitalias, female cibarial armature and complete chaetotaxy of pupa and larva show that it can be distinguished from Anopheles albitarsis from the type-locality and other areas by the paler general external appearance of the adult, the posterolateral tufts of scales, on the female abdominal terga and the branching of the outer anterior clypeal seta (3-C) of the fourth instar larva (as shown in illustrations). If species can also be distinguished from An. albitarsis from the type locality by the allele frequencies at 11 enzymic loci as represented by Nei's Genetic Distance.
