Crematogaster (Crematogaster) chiarinii Emery

return to key {link to the Hymenoptera Name Server} Type location Ethiopia (Cremastogaster Chiarinii n. sp., Emery, 1881a: 271, illustrated, worker; Forel, 1892e: 353, queen & male) from Kaka - see below
subspecies
taediosa (Cremastogaster taediosa n. spec., Forel, 1894b: 98, worker; as subspecies of chiarinii by Emery, 1915g: 12) from Ethiopia, Südabessinien, Ilg - see below
v-nigra (Cremastogaster chiarinii Em. var. V. nigrum n.var., Forel, 1910e: 434, worker - NOTE the "nigra", Forel, 1910e: 434, worker, in Bolton, 1995: 158, is an error) from Congo - see below
all forms described (see Bolton, 1995) .


{Crematogaster chiarinii}Emery's (1881a) description is at {original description}. Forel's (1892e) descriptions of the queen & male is at {original description}. Forel's (1894b) description of taediosa is at {original description}. Forel's (1910e) description of v-nigra is at {original description}.


Note: with fresh specimens from Ethiopia that match Emery's description and drawing, it seemed clear that the type form is unicoloured dark brown to near black and has carton nests on trees. With fresh specimens from acacia in Sudan that appear to be close to the description given by Emery (1896i) for the variety cincta, I separated the distinct forms with a general yellow-brown or red-brown colour and darker gaster, with paler appendages, also short propodeal spines to a separate species Crematogaster cincta. Thus I have moved cincta, aethiops, bayeri, sellula and subsulcata. The availability of type images from Antweb (February 2014, December 2014) confirm my opinion. The images also make it seem likely that Crematogaster affabilis is no more than larger workers of chiarinii.

Wheeler (1922) has many records from East Africa and into Saudi Arabia. It is likely that those were mostly if not all cincta.

Collingwood (1985) separated it from other species recorded from Saudi Arabia by - head wider than long; petiole about as wide as long; alitrunk paler than head or gaster, propodeal spines more than 0.2 mm; also more strongly sculptured than affabilis (type location Somalia); mesonotum with keel.
