Updating Ecological and Behavioral Aspects of the Sandfly Fauna in the Vale do Ribeira Region, São Paulo State, Brazil.

Some ecological parameters and the distribution of vectors in the municipality of Eldorado, Vale do Ribeira Region, São Paulo, were studied. Entomological surveys were carried out from September 2019 to March 2021. It was observed that a few ecological parameters, including richness, abundance, diversity, and equitability, were typical of a modified environment, where artificial ecotopes maintain the presence of sandflies throughout the year. A total of 11,668 sandflies were captured. The presence of five taxa were observed in Eldorado, with low diversity and high dominance of Nyssomyia intermedia next to Ny. neivai, which are sympatric species. The results presented reinforce the importance of these species in anthropized areas in the transmission of cutaneous leishmaniasis (CL) agents and the need for entomological monitoring. Psathyromyia pascalei was encountered for the first time in the municipality, expanding the known area of distribution of this species in a modified environment.

A New Species of Sand Fly, Psathyromyia elizabethdorvalae sp. n. (Diptera: Psychodidae: Phlebotominae), From Brazil.

A new species of phlebotomine sand fly, Psathyromyia elizabethdorvalae sp. n. Brilhante, Sábio & Galati from Xapuri, Acre state, Brazil, is described, with illustrations of male and female adults.

On the Synonyms of Psathyromyia (Psathyromyia) shannoni (Dyar, 1929) and Pa. bigeniculata (Floch & Abonnenc, 1941) and the Resuscitation of Pa. pifanoi (Ortiz, 1972) With the Description of Its Female (Diptera: Psychodidae: Phlebotominae).

Psathyromyia shannoni until recently presented several taxa: Phlebotomus limai, Ph. bigeniculatus, Ph. pifanoi, and Ph. microcephalus as its junior synonyms. In a previous study, the two former synonyms were resurrected and here a revision based on morphological characters of the taxonomic status of Ph. microcephalus and Ph. pifanoi is presented. Psathyromyia pifanoistat. rev.; comb. n. is resurrected from the synonymy of Pa. shannoni and its female is described. Phlebotomus microcephalus is removed from the synonymy of Pa. shannoni and proposed as a new synonym of Pa. bigeniculata. Lutzomyia cuzquenasyn. n., occurring in the Amazon region, is designated as a junior synonym of Pa. pifanoi. The geographical distributions of Pa. shannoni, Pa. bigeniculata, and Pa. pifanoi in the Americas are presented.

Species diversity of sandflies (Diptera: Psychodidae) during different seasons and in different environments in the district of Taquaruçú, state of Tocantins, Brazil

Phlebotomine sandflies are the vectors for the protozoan parasites that cause leishmaniasis. The present study investigated the species composition of sandfly fauna in the rural district of Taquaruçú, municipality of Palmas, state of Tocantins, Brazil and compared the diversity of species among intradomicile, peridomicile and forest environments during the dry and rainy seasons. Sandflies were collected using CDC light traps over the course of three months during the dry and rainy seasons. A total of 767 specimens were captured, belonging to different 32 species. The most abundant species were Micropygomyia goiana (Martins, Falcão & Silva), Sciopemyia sordellii (Shannon & Del Ponte), Evandromyia carmelinoi (Ryan Fraiha, Lainson & Shaw), Evandromyia termitophila (Martins, Falcão & Silva), Nyssomyia whitmani (Antunes & Coutinho) and Lutzomyia longipalpis (Lutz & Neiva). The highest species diversity (30) and the greatest percentage of specimens (78.3%) were obtained during the rainy season. During the dry season, the species richness and abundance were greater in domestic environments. However, during the rainy season, the forest displayed the highest species richness and the domestic environment exhibited the greatest species abundance. Several important vector species are reported in this study.

Phlebotomine sand flies (Diptera: Psychodidae: Phlebotominae) of Alagoas state, northeast of Brazil / Flebotomíneos (Diptera: Psychodidae: Phlebotominae) de Alagoas, nordeste do Brasil

The phlebotomine sandflies of the state of Alagoas are poorly known, with more than 40 years since the last report on sandflies in the state. In here, Psathyromyia brasiliensis (Costa Lima), Micropygomyia quinquefer (Dyar,) and Evandromyia termitophila (Martins, Falcão & Silva) are registered for the first time in Alagoas. This report increases to nine the number of species collected in the state, including Lutzomyia longipalpis (Lutz & Neiva), Migonemyia migonei (França), Nyssomyia whitmani (Antunes & Coutinho) and Nyssomyia intermedia (Lutz & Neiva), all vectors of Leishmania in Brazil.

A fauna flebotomínica do Alagoas é uma das menos conhecida, sem registro de informações há mais de 40 anos. O presente trabalho registra Psathyromyia brasiliensis (Costa Lima), Micropygomyia quinquefer (Dyar) e Evandromyia termitophila (Martins, Falcão & Silva) pela primeira vez em Alagoas. Aumenta, assim, para nove o número de espécies conhecidas no estado, incluindo-se Lutzomyia longipalpis (Lutz & Neiva), Migonemyia migonei (França), Nyssomyia whitmani (Antunes & Coutinho) e Nyssomyia intermedia (Lutz & Neiva), importantes vetores de Leishmania no Brasil.
