2 males in alcohol, October 30, 2015, Vietnam, Lao Cai Prov., Sa Pa Distr., Ban Khoang env., 22.3872N, 103.7867E, 1682m a.s.l. Wing length ca. 4.8mm. Antennae 14-segmented, long (ca. 2mm or 0.4 length of wing), first flagellomere the longest segment. Three ocelli present. Only hind tibiae with a spur-like setose appendage, longer than tibia width, or ca. two-thirds of tarsomere 5. Coxae not elongated, trochanters ventrally with black streaks, the longest ones on hind trochanters. General colouration brownish yellow, thoracic dorsum darker. I moved from Nepaletricha to Hesperinidae to Mycetobiidae, all rejected because of the present combination of characters. Wings badly deformed in alcohol so here's my sketch, the venation is rather peculiar, I couldn't make out any of subcostal vein (too weak, too short?). Dotted lines show where veins (in my view at least) seemed evanescent, almost like folds. [Subject changed from Nematocera, Vietnam - which family?? to Blephariceridae, Philorus, Vietnam.

Male genitalia, dorsal, lateral (not so good, just to get the general idea), and ventral views.

General head shape reminds me of Ceratopogonidae but then the antennae are off. I asked Peter Chandler for his opinion.

Thanks Paul, yet I believe Ceratopogonidae got no ocelli... |

And that is in addition to the wrong antennae.

Could you check against Blephariceridae (Philorus)?

Well Paul I think you're quite right, elongated mouthparts, antennae of 13 to 15 segments, Sc rudimentary, hind tibiae with 1 or 2 spurs, male genitalia of similar structure. I omitted Blephariceridae because in Stackelberg it is considered that vein C is developed in whole wing, while Courtney writes that C reaches only the apex of R5. |

I think the closest match is Philorus assamensis (Tonnoir, 1930) [Notes on Indian blepharocerid larvae and pupae with remarks on the morphology of blepharocerid larvae and pupae in general. Records Indian Mus. 32(2), pp. 207-209], as Euliponeura, synonimysed by Zwick in 1990. Couldn't find any proper records of Blephariceridae from Vietnam... |

Without species, two genera are mentioned in this paper: https://www.acade...etnam_2008.

By the way, Zwick & Arefina (2005) establish there is a clearly monophyletic group within Philorus for which the name Euliponeura is available but recognizing it as a valid genus would render the remainder of Philorus paraphyletic...
