SPINELLI, Gustavo R.  and  DIAZ, Florentina. A new species and new records of Amerohelea from Peru (Diptera: Ceratopogonidae). Rev. Soc. Entomol. Argent. [online]. 2024, vol.83, n.1, pp.19-22.  Epub Feb 25, 2024. ISSN 0373-5680.

A new species of the genus Amerohelea Grogan & Wirth (Diptera: Ceratopogonidae), Amerohelea robusta sp. nov., collected at light in the Amazon area of Peru is described and photographed. This new species, known only by males, is compared with Amerohelea xerophila Gaddi, Spinelli & Grogan from arid zones of Argentina. The later species mainly differs by the distinctly shorter distal portion of parameres, the Y-shaped aedeagus with basal arm recurved more than 90°, and the eyes broadly separated. Besides, Amerohelea fasciata Grogan & Wirth and Amerohelea galindoi Grogan & Wirth are firstly recorded from Peru.

Keywords : Amazon; Amerohelea robusta; Palpomyiini; Predaceous midges.
