With those antennal ratios, and the dark patch on the postmentum, I'd say this was Brillia modesta or close.

@TOny Merci beaucoup. Great answer ! Brillia genera DIAGNOSIS: Distinguished by the well developed pectinate labral lamellae; plumose S I; 4 segmented antenna with segment 2 divided in basal third by a weakly sclerotized area; antennal blade subequal to flagellum; distinctive mentum; posteriorly displaced setae submenti (near posterior margin of head capsule); and procerci and anal tubules present. As i did not have more info... I have been stopped. Brillia flavifrons impossible (different apotome and labral sclerites, different mentum) Perhaps Brillia parva ? in Belgium records of Brillia modesta (Meigen, 1830) Nevertheless... Brillia is enough for my purpose. Thanks a lot. SDS Edited by solito de solis on 13-01-2018 21:29 |

Apologies - I should have checked for name changes! Brillia modesta is now known as Brillia bifida. The species identification was based on Cranston's 1982 Key to the larvae of the British Orthocladiinae.

Apologies accepted  Brillia names have several times been changed. Sometimes I got lost too. In the Netherlands there are 2 species of Brillia: Brillia bifida (syn. Brillia modesta) with a black gula spot and Brillia longifurca (syn. B. flavifrons). without a gula spot....so B. bifida for sure. Edited by atylotus on 14-01-2018 11:20 |
