Description of six new large species of Argentinomyia Lynch-Arribálzaga, 1891 and redescription of Talahua fervida (Fluke, 1945) (Diptera, Syrphidae, Syrphinae)

Abstract

The morphological similarities between five new large Argentinomyia species and Talahua fervida Fluke are characterized and presented. Six new species of Argentinomyia (10–12 mm long) are described: Argentinomyia andina Montoya & Wolff, sp. nov. (Colombia), Argentinomyia choachi Montoya, sp. nov. (Colombia), Argentinomyia quimbaya Montoya & Wolff, sp. nov. (Colombia), Argentinomyia huitepecensis Montoya, sp. nov. (México), Argentinomyia puntarena Montoya, sp. nov. (Costa Rica), and Argentinomyia talamanca Thompson, sp. nov. (Costa Rica). The genus Talahua Fluke is re-diagnosed and, Talahua fervida redescribed. A taxonomic key and a comparison of diagnostic characters are presented. Photographs of head, abdominal and wing maculae patterns, as well as illustrations of male genitalia are provided for species identification.

Generic diversity of the predaceous fungus gnats (Diptera: Keroplatidae) from Colombia

“…The generic review of the Keroplatidae present in Colombia shows that the family is widely distributed covering va-rious ecosystems at different altitudinal ranges in the country. The greatest diversity of the family is concentrated in the Andean mountains, and this could be explained due to the increased sampling efforts carried out in these ecosystems during the last 10 years to uncover the diversity and ecology of some groups of paramo dipterans (e.g., Montoya and Wolff 2020, Henao-Sepúlveda et al 2019, 2023. ).…”
