return to key return to listIran list {link to the Hymenoptera Name Server} Type location Egypt (Myrmecocystus viaticus F. subsp. Diehlii Forel var. Isis n.var., Forel, 1909e: 385; Forel, 1913d: 434, worker; raised to species Collingwood, 1985: 288) from Suez, collector M. Bugnion; worker only known.

Forel's (1909e) description is with his diehlii redescription at {original description}. Santschi (1929b) gave notes on Cataglyphis bicolor F. stirps nigra Andre v. isis (Forel), these are at {original description}.

In bicolor species-group (Agosti, 1990: 1489).

Egypt records - in HNS as Myrmecocystus (Cataglyphis) diehlii var. isis Forel - Forel (1909e) gave it as found at Suez, Egypt, by M. Bugnion; Forel (1913d: 434) simply cited the name as recorded from Heliopolis; Santschi (1929b: 51) had - Suez (Bugnion), workers, types, Heliopolis (Sahlberg), worker.

{Cataglyphis funiculi}Collingwood (1985) described it as related structurally to diehlii in having proportionately shorter funiculus segments and a short thinner petiole node. It differs from diehlii in having a strongly pubescent [greyish-white pubescence, according to Forel, 1909e] alitrunk and occasional erect hairs on the scapes. TL not exceeding 9.5 mm.

{Cataglyphis isis}The photomontage of the above type worker is colour adjusted to reduce the magenta tint characteristic of all Antweb images. Forel (1909e) gave the colour as entirely black, save for a reddish tint on the head of some largest workers.

The label shows the collector as Bugnion, so it appears to be from the original type collection. Forel (1909e) gave the petiole node as "plus mince", i.e. narrower, which is clear in the image as a shorter node with a vertical rear face.

{Cataglyphis isis}The photomontage of a worker identified by Santschi (1929b) is collated from
The label shows the collector as Sahlberg and the location as Heliopolis, i.e the second set of samples listed by Santschi. It is some 8% larger than the type, assuming both to be major workers; has a evenly domed  petiole in lateral view, with a convex posterior face; and, is darker, including the scapes and palps.
