On the identity of Prochyliza nigrimana (Meigen) and Prochyliza nigricornis (Meigen) (Diptera: Piophilidae), with a synopsis of Prochyliza Walker and description of a new species Author Martín-Vega, Daniel text Zootaxa 2014 3893 2 277 292 journal article 10.11646/zootaxa.3893.2.7 4c1f0cda-f6d1-4faf-bb42-a8163dd4ccae 1175-5326 224982 2380C8F6-0B98-460E-97E1-51BEE0F519A5 Prochyliza inca McAlpine, 1977 Prochyliza inca McAlpine 1977 : 46 . Type locality: Ecuador (Azuay). Holotype (♂) and paratypes (4 ♀) in CNC. Material examined. 1 ♀ ( CNC , paratype ): Ecuador , Azuay, Tarqui; 07–08.iii.1965 . 1 ♂ ( CNC ): Ecuador , Azuay, Santa Isabel; 10–13.iii.1965 ; det. A. L. Ozerov. Diagnosis. The two horn-like spines on the epandrium of P. i n c a males ( Fig. 5 D) are extremely distinctive. The following combination of characters is also distinctive of P. i nc a : lower quarter or less of the frons orange; gena black; front coxa entirely yellow; mid and hind femora and mid and hind tibiae mostly black; margins and fringes of calypters brownish; males with posterior margin of sternite 5 strongly emarginated. Remarks. According to McAlpine (1977) , P. azteca would be the most closely related species to P. inca . In the absence of a description for P. azteca male morphology, the presence of two horn-like spines on the epandrium of P. inca ( Fig. 5 D) appears to be an unique character among the Piophilidae . Biology. Unknown. Distribution. Neotropical; only recorded from Ecuador ( McAlpine 1977 ; Ozerov & Norrbom 2010 ).
