Ordo: Hymenoptera
Familia: Chrysididae
Genus: Loboscelidia
Name
Loboscelidia nasiformis Kimsey, 2012 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype male: Thailand: Petchaburi Prov., Kaeng Krachan NP, Pa La-U/Huai Palao Forest Unit 3, 12°32'149"N, 99°28'265"E, Malaise trap, 4-11/i2009, Thongbai, T4562 (QSBG).
Diagnosis
The most distinctive and unusual feature of this species is the greatly elongate and nose-like frontal projection, which makes the head nearly 3× as long as broad in lateral view. Otherwise, Loboscelidia nasiformis is closest to Loboscelidia cinnamonea, with an arched medial vein, rectangular frontal projection (albeit greatly elongate in Loboscelidia nasiformis), complete notauli, cu-a reduced to a tiny stub or absent, and no scrobal sulcus. Other than the elongate frontal projection, Loboscelidia nasiformis can be separated from Loboscelidia cinnamonea by the presence of fore and midtibial flanges (absent in Loboscelidia cinnamonea).
