Cephalosphaera Enderlein and Neocephalosphaera De Meyer (Diptera: Pipunculidae) of Colombia, with description of nine new species and an updated key to their Neotropical species

Abstract

Cephalosphaera Enderlein, 1936 and Neocephalosphaera De Meyer, 1994 have a cosmopolitan distribution and they include a few studied species in the Neotropical region. Both genera are entirely unknown in Colombia. One new species of Cephalosphaera and eight of Neocephalosphaera are described from protected areas and from conflict-territories of limited access in Colombia, namely, Cephalosphaera munchiquensis sp. nov. (type locality: Parque Nacional Natural Munchique, La Romelia, Cauca, 2640 m), Neocephalosphaera carinae sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Cabaña Mamarramos, Boyacá, 2855 m), N. grisea sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Quebrada Los Mudos, Boyacá, 2840 m), N. iguaquensis sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, El Nispero, Boyacá, 2730 m), N. muisca sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá, 2855 m), N. paolae sp. nov. (type locality: San José del Fragua, Caquetá, 1270 m), N. spinifera sp. nov. (type locality: Santuario de Fauna y Flora Los Colorados, Alto El Mirador, Bolívar, 400 m), N. spiralis sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Quebrada Carrizal, Boyacá, 3350 m) and N. sumapazensis sp. nov. (type locality: Parque Nacional Natural Sumapaz, Cabaña Las Mirias, Meta, 735 m). Illustrations and a dichotomic key to the Neotropical species of these two genera are 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.…”
