Alloxysta fracticornis

Overview & Synopsis

Alloxysta fracticornis (Thomson, 1862)Figs 2.17, 4.15Allotria fracticornis Thomson, 1862: 408. Type: deposited in MZLU (examined).Allotria (Allotria) fracticornis – Dalla Torre & Kieffer 1902: 40.Charips (Charips) fracticornis – Dalla Torre & Kieffer 1910: 281.Alloxysta fracticornis – Andrews 1978: 83.DiagnosisAlloxysta fracticornis is mainly characterized by a closed radial cell that is 2.2 times as long as wide (Fig. 4.15); the absence of pronotal carinae; the presence of propodeal carinae; and male and female antenna with rhinaria beginning on F3, F1–F3 subequal in length (Fig. 2.17), and curved F 3 in males. It is similar to A. mullensis, but can be differentiated by the F1–pedicel proportion (F1 is longer than pedicel in A. fracticornis (Fig. 2.17), but subequal to pedicel in A. mullensis (Fig. 2.28)), flagellomere proportions (F1–F3 are subequal in length in A. fracticornis (Fig. 2.17), but F1 is longer than F2 and F2 is subequal to F 3 in A. mullensis (Fig. 2.28)), and flagellomere shape (F3 is curved in A. fracticornis males, but no flagellomeres are curved in A. mullensis males).Material examinedLectotypeSWEDEN: ♂ [fracticornis (gray label, handwritten)], [fracticornis (handwritten)], [Lectotype Allotria fracticornis Thomson, 1862 ♂ desig.
