Alloxysta apteroidea Hellén, 1963: 23 . Type: deposited in MZH (examined).

Diagnosis

Alloxysta apteroidea is mainly characterized as a brachypterous species and by the absence of a visible radial cell; the fore wing being practically absent; the absence of pronotal and propodeal carinae; and antenna with F1 shorter than pedicel and F1 longer than F2 and subequal to F3 (Fig. 2.3). It is similar to A. pedestris, but can be differentiated by the length of the fore wings (which are very short and practically absent in A. apteroidea, while they reach the beginning of the metasoma in A. pedestris) and the proportion of F1–pedicel (F1 is shorter than pedicel in A. apteroidea (Fig. 2.3), but F1 is longer than pedicel in A. pedestris (Fig. 3.1)).
