Hello, Christian Marty : Guyane française : Remire-Montjoly : 97354 : 02/06/2016 Altitude : NR - Taille : 15 mm Réf. : 163998 This picture was shown on our French forum and we are rather clueless about the genus, even more about the family. Could you shed some light? Thanks a lot in advance. Pierre Duhem |

It looks like Tipulidae (sensu lato) but I can't see details. |

I'd suggest Polymera (Limoniidae)

The genus is one of the most typical for the area, with 58 Neotropical spp. known so far. Although venation is not clearly visible, I think we can put a name on this: Polymera (s.str.) hirticornis (Fabricius, 1805). Here we can see what is mentioned in Alexander, 1913d (Proc. U. S. Nat. Mus. 44: 532): head and palpi mostly orange-yellow, scape and pedicel brownish-yellow, flagellomeres darker, antennae longer than body, pronotum yellow, prescutum, scutellum and mediotergite mostly brown, pleurae brown and (anteriorly) yellow, femora with brown subapical ring, hind tarsi white, wing brown with conspicuous pale yellow cross-band. I quote the original description from Fabricius, 1805 (Systema antliatorum..., p. 46), recapitulated in Wiedemann, 1821 (Diptera Exotica, Pars I, p. 37) Ater alis fuscis: fascia albida, antennis longis, verticillato pilosis. Antennae corpore longiores, nigricantes, multiarticulatae: articulis pilis longioribus verticillatae; articulo primo longiore, ferrugineo. Thorax ater, antice ferrugineus. Abdomen compressum, nigrum, subtus ferrugineum. Alae fuscae; fascia lata alba. Pedes elongati, testacei. P.S. Not recorded from French Guiana, but known from Guyana (Edwards, 1934b, Ann. Mag. Nat. Hist. (10) 14: 635 ) Edited by Dmitry Gavryushin on 22-06-2016 10:57 While others can't climb, using infinite pains, I, gravity turning to jest, Ascend, with all ease, perpendicular planes, Rough or smooth, just as pleases me best. |
