New genus of Psychodinae (Diptera, Psychodidae) from Argentina

Abstract

ABSTRACT. Adults (male and female) and pupae of Chuspilepia saltenia gen. nov., sp. nov. were collected in tree holes in the Yungas rainforest, near San Ramón de la Nueva Orán city, Salta province, Argentina. It was not possible to place this new species in any known genera using the available keys and published descriptions, thus a new genus is proposed for the Neotropical region of Argentina.

First record of Neurosystasis Satchell in Mexico, with the description of one new species (Diptera, Psychodidae), and the validation of Chuspilepia Omad, Mangudo & Gleiser as subgenus

“…This new species appears similar to Neurosystasis saltenia (Omad, Mangudo & Gleiser, 2015) because R2+3 is attached to vein R4, the wing membrane is infuscate with dark spots on vein apices, and lacks sensory organs near the apex of Sc. Also, the male genitalia has the epandrial lobe with a wide base from which a short median branch originates, and no apical retinaculum, but has more than ten cone shaped setae in the apical third and 2-3 long curved setae at apex.…”

“…Wing sensory organs near the apex of Sc absent; vein apices with dark spots; R2+3 fork attached to base of R4. Omad, Mangudo & Gleiser, 2015 (Satchell, 1955) (Kvifte & Wagner 2017).…”

“…Kvifte and Wagner (2017) presented the diagnosis of Neurosystasis, a key for the identification of the previously known species, and the description of two species. This genus currently comprises six species, one recorded in Florida, USA (Satchell, 1955), three from Cuba (Knab, 1914;Kvifte & Wagner, 2017), one from Jamaica (Wagner & Hribar, 2010), and another one described in Argentina (Omad et al, 2015), far away from the Caribbean subregion where the bulk of species occur.…”

“…Neurosystasis longistylis sp. nov. is similar in appearance to Neurosystasis saltenia (Omad, Mangudo & Gleiser, 2015), but is readily distinguished based on characters of the head, wing, and male genitalia. In both species, R2+3 is attached to vein R4, the wing membrane is infuscate with dark spots on vein apices, and lacks sensory organs near the apex of Sc, characters not present in other species of Neurosystasis, and for that reasons we proposed the recovery of Chuspilepia from its synonym and validate it as a subgenus of Neurosystasis to include both continental species.…”
