targuius (Cataglyphis (Cataglyphis) albicans Rog. v. targuia n. var., Santschi, 1929b: 55, footnote, worker; Santschi, 1929c: 106) from Algeria - see  http://www.antweb.org/specimenImages.do?code=casent0912177 distribution.

Note - we have removed the subspecies Cataglyphis franchettii to the status of full species, with specimens collected at St Katharine's, Sinai, Egypt, by Mike JamesCollingwood & Agosti (1996) raised Cataglyphis auratus Menozzi  and Cataglyphis vaucheri (Emery) to species. Also separated are the Cataglyphis lividus forms, generally yellowish to red with darkish gasters.

Cataglyphis cubicus (Myrmecocystus albicans r. cubicus n. st., Forel, 1903c: 267, worker & queen) from Morocco, Tangier collected by Arthur Müller, listed as a species by Cagniant (2006, 2009). - see  http://www.antweb.org/specimenImages.do?code=casent0911103


{Cataglyphis albicans vaucheri}Roger's (1859) description is at {original description}. Forel's (1903c) description of cubicus is at {original description}. Emery's (1906b: 177) description and illustrated notes on the male is at {original description}. Emery's (1906d) description of vaucheri is at {original description}. Santschi's (1912c) description of kairouanus is at {original description}. Santschi's (1912c) description of targuius and other notes is at {original description}. Bernard's (1948) description of fezzanensis and notes is at {original description}. Arnol'di's (1964) description of armenus is at {original description}.


The distinctive colouration and pubescence strongly suggests armenus should be separated and I have given it a separate page with, along with a fresh worker from Iran - see Cataglyphis albicans armenus.


Cataglyphis albicansForel (1895d) on mixtus had as v. lividus but reddish with the gaster behind and below blackish; larger and the head longer. Emery (1906d) had the worker, TL 6 mm, head 1.6 X 1.7 mm, posterior tibia 2 mm; black with submetallic reflections, appendages brown. Santschi (1912c) wrote of the type form as being from the Algerian Atlas, being black, with the major and minor all with the head entitrely smooth and shiny. His varieties kairouna and opaca had the majors with matt variably longitudinally striate heads.
Writing of specimens collected in Egypt (Sinai) Finzi (1936) described the species as uniformly piceous-brown, appendages reddish-yellow; wholly sublucid (semi-shiny), due to overall fine dense striations; erect hairs sparse on the clypeus, occipitum, propodeum and margins of gaster segments. He noted the specimens were identical to others in his collection from Tunisia. The major shown below appears closer to the Finzi description of colour but conforms to the Santschi drawing as regards alitrunk morphology.

Colour variations:
cubica is yellow-brown, the head and alitrunk concolorous contrasting with a shiny dark brown gaster.
fezzanensis has the same base colour as cubica but the gaster is a distinctive yellow-brown.
opacus is a unicolorous dark brown.
targuia is similar to opacus but with a lighter brown head.

{Cataglyphis albicans}The photomontages are of workers collected in the Sinai Desert, Egypt, St Katherine Protectorate around the town of St Katherine, in mountains above 1500m, in 2010 by Amy Shepherd, a research student of Francis Gilbert.

These especially the major differ somewhat from the poor description of the type in appearing to be more red. They do appear close to other modern specimens, e.g. https://www.antweb.org/specimenImages.do?code=casent0900322, from Morocco.
