Cephalops Fallén and Semicephalops De Meyer (Diptera: Pipunculidae) of Colombia, with description of five new species and an updated key to males of the Neotropical species

Abstract

The pipunculid genera Cephalops Fallén, 1810 and Semicephalops De Meyer, 1994 are cosmopolitan in distribution. These two genera have just a few species known from the Neotropical Region and they were completely unknown to Colombia. Four new species of Cephalops and one species of Semicephalops are described from protected areas and conflict-territories of limited access in Colombia, namely Cephalops acutus sp. nov. (type locality: Cañaveral, Magdalena), C. gracilis sp. nov. (type locality: El Níspero, Boyacá), C. klinsmanni sp. nov. (type locality: Las Brisas, Caquetá), C. lobatus sp. nov. (type locality: El Níspero, Boyacá) and Semicephalops folium sp. nov. (type locality: Quebrada Carrizal, Boyacá). With this paper, the number of Cephalops species from the Neotropical Region increase from 13 to 17 and that of Semicephalops from five to six. Cephalops amapaensis Rafael, 1990 and Semicephalops inpaganus Rafael, 1990 are recorded for the first time from Colombia, and amended diagnosis are provided for both. A dichotomic key to the Neotropical species of both genera is presented.

“…It is important to highlight that the four species listed in the present study occur in the SFF Iguaque. This indicates that this place harbors a high species richness, and that the species are possibly endemic to the region and the country, which urgently calls for developing and prioritizing conservation and management plans by the country's governmental entities of Santuario de Fauna y Flora Iguaque as a flagship/hotspot of the species diversity, in agreement with what has been reported by Ramos-Pastrana et al (2022b, 2022c.…”

“…The external morphological terminology follows Cumming & Wood (2017). The measurements (in millimeters) that refer to the head, antenna and wing were made as proposed by Skevington (2002), Kehlmaier (2005a), Ramos-Pastrana et al (2022a, 2022b, 2022c: F, length of frons; EM, length of eye contiguity; V, length of vertex; LW/ MWW, ratio between length and maximum width of the wing; LTC/ LFC, ratio between length of third costal section by length of fourth costal section of the wing; LPP/ WPP, ratio between length and maximum width of the postpedicel. The morphological terminology of the terminalia of male follows Skevington (2002), Kehlmaier (2005a) Motamedinia et al 2017Motamedinia et al , 2020Ramos-Pastrana et al (2022a, 2022b, 2022c.…”
