Cataglyphis isis (Forel)

return to key Type location Egypt (Myrmecocystus viaticus F. subsp. Diehlii Forel var. Isis n.var., Forel, 1909e: 385; later reported from Heliopolis, as Myrmecocystus diehlii For. v. isis (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.

Note that Collingwood had "Cataglyphis isis Pisarski, 1967 n. stat.) citing "Cataglyphis diehlii (ssp.) isis Pisarski, 1967: 421". Nothing of the sort appears in the Pisarski paper. It is not among the reported Cataglyphis from Afghanistan and page 421 is one of the reference list pages.

{Cataglyphis isis}The photomontage (right) of a type worker is collated from the images at http://www.antweb.org/specimen.do?name=casent0249889.


{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.
