The first Dexiinae from Mauritius: the description of a new species of Pandelleia Villeneuve, 1907 (Diptera, Tachinidae)

Abstract

A new species of the Afro-Palearctic genus Pandelleia Villeneuve, 1907 (Diptera: Tachinidae), P. crosskeyi sp. nov., from Mauritius is described. This is the first Dexiinae to be described from Mauritius. In addition, this new species corresponds to the ninth species for this genus, and the third in the Afrotropics. The main external features that distinguish it from the other species in this genus is the abdomen that lacks the pair of small, round and dark brown spots, vein M ending in R₄₊₅ at a 90° angle, and female with dark brown scutellum.

Pseudolycoriella hygida (Sauaia and Alves)—An Overview of a Model Organism in Genetics, with New Aspects in Morphology and Systematics

“…The following data were employed for the scheme construction: Pseudosciara pubescens (Morgante, 1969) (as Trichosia) [45,46], Rhynchosciara americana (Wiedemann, 1821) [21,46,47], Schwenckfeldina sp. (as 'Schwenkfeldina'; misspelling) [21,46], Lycoriella ingenua (Dufour, 1839) (as Sciara pauciseta) [48], Bradysia tilicola (Loew, 1850) (as Sciara coprophila) [49], and Pseudolycoriella hygida (Sauaia & Alves, 1968) (as Bradysia) [50].…”

“…The identification of species was carried out according to the keys, descriptions, and figures by several authors [1,[3][4][5]7,25,[61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80]. The morphological terminology follows [7,70,81], with some minor adaptations to abbreviations (see Section 2.5, 'Morphological abbreviations').…”

“…Literature in systematics: Bradysia hygida Sauaia & Alves- [25]: 85, plate 1, Figures 1-6, plate 2, Figures 7-13…”

“…Pseudolycoriella hygida (female adult in Figure 1) was originally described by Heni Sauaia and Maurílio A.R. Alves as a species of Bradysia Winnertz, 1867 [25] and recently moved to the genus Pseudolycoriella [26]. Rearing this species in the laboratory began with two females in 1965 in the Cellular Biology Laboratory of the Medical School of the University of São Paulo in Ribeirão Preto.…”

“…Rearing this species in the laboratory began with two females in 1965 in the Cellular Biology Laboratory of the Medical School of the University of São Paulo in Ribeirão Preto. The species was formally described with considerable detail based on adults [25], and the culture has been successfully maintained ever since. In 2016, the culture was transferred to the School of Pharmaceutical Sciences on the same university campus.…”
