Type locality. Egypt, Gebel Elba [= Jabal Elba].

Type material. According to Koch (1952), the only type specimen should be deposited in Entomological section of the Ministry of Agriculture at Dokki in Egypt. I contacted several responsible persons (long time before the Egyptian revolution in February 2011) from the Plant Protection Research Institute, which is a new name for the latter, but without success. Therefore for comparison I used specimens which perfectly agree with Koch´s (1935a) description and which were collected at the type locality (Jabal Elba).

Remarks. Koch (1935a) described Adelostoma hirsutum Koch, 1935 from Egypt. Later Gridelli (1940) synonymised it with Adelostoma abyssinicum Haag-Rutenberg, 1872 without any comparison of type specimens. Koch did not agree and forwarded type of A. abyssinicum to prof. Priesner (Cairo, Egypt) to compare it with type of A. hirsutum . Priesner was able to find only two, in my opinion weak, characters (different punctation and setation of elytra) on which he decided that these two “species” are at least two geographic races of the same species. Koch (1952: 28) published these results without any further comments. Ardoin (1976) and Purchart (2007) accepted these two “species” as subspecies. During my study of the subgenus Zarudnionymus I examined larger series of these two taxa and found further two constant characters (differences in body size and punctation of reflected portion of elytra). The latter are, especially when combined with characters found by Priesner, useful to distinguish these two taxa reliably. However, as there is no really strong character that could at first sight separate them from each other I prefer to retain them as subspecies together with the new subspecies described below.
