Remarks
Pont (1995: 95) listed 16 male and 7 female syntypes. However, in the present study 11 male and 8 female specimens can be attributed to this species. Among further material that had been left unsorted some specimens belonging to this species could be recognized albeit with difficulty. Two specimens from among those listed as syntypes are in very poor condition, one being also headless and the other consists only of minute unrecognizable fragments of the hypopygium mounted in Euparal. These are left undetermined. Given the difficulties in sorting out these specimens to recognize the species intended by Collin, and to reliably separate it from other very similar species recently described, it is necessary to designate a lectotype. A male in good condition from among the series of both sexes collected at Fayoum, Lake Karun; 2–23 Sep. 1945 is here designated lectotype.
In its habitus ( Fig. 50A View Fig ), this species is almost identical to A. oculicauda Collin, 1949 , as Collin himself appreciated when he described the two species. Both have very short fronto-orbital and scutal setae ( Fig. 50B View Fig ). The male hypopygium is highly distinctive in both species, even without dissection as long as it is sufficiently exposed ( Fig. 50C View Fig ). Females are very difficult to separate. Although the features used in the key are present in most specimens, they are absent in some, and overlap does occur with other species. When this is the case, identification is more reliable if the specimens are associated with males.
