Crematogaster (Crematogaster) capensis Mayr

Type location South Africa (Cremastogaster capensis n. sp., Mayr, 1862: 764, worker & queen; Mayr, 1865: plate IV, had illustrations) Cape of Good Hope, Novara - see below

calens (Cremastogaster capensis Mayr, var. calens n. var., Forel, 1910e: 435, worker) from Mozambique, Delagoa, Dr Liengme - see below.
tropicorum (Cremastogaster capensis Mayr, subsp.. tropicorum n. subsp., Forel, 1910e: 435, worker) from Mozambique, Ibo - see http://www.antweb.org/specimenImages.do?code=casent0908502
defleta (Cremastogaster opaciceps Mayr subsp. defleta n. subsp., Forel, 1910e: 434, worker) from South Africa, in Acacia horrida - see below.
worker and queen described (see Bolton, 1995) .

Mayr's (1862) description is at . Mayr (1865) gave a fuller illustration, this is at (note the scale line on the worker appears to be 0.5 mm, from the TL given by Mayr). Forel's (1910e) description of calens & tropicorum is at . Arnold (1920a: 512) gave a translation, this is at . Forel's (1910e) description of defleta is at . Arnold (1920a) gave a translation of the opaciceps type plus that of defleta, this is at .

The photomontage of the type worker (from the Mayr collection in Vienna) is collated from http://www.antweb.org/specimen.do?name=casent0919661
Size from Antweb scales - TL ca 3.4 mm, HW 0.78 mm. Mayr gave the size as TL 4-4.5 mm. This suggests the Antweb scale is wrong as the calens and tropicorum types all fit the Mayr size.

The photomontage of the calens type worker is collated from http://www.antweb.org/specimen.do?name=casent0908501
Size from Antweb scale = TL ca 4.2 mm; HW 1.39.

The photomontage of a syntype worker of defleta is collated from http://www.antweb.org/specimen.do?name=casent0908547

The photomontage of a "syntype" worker in the BMNH is collated from http://www.antweb.org/specimen.do?name=casent0902087.
This may be mislabelled as it clearly differs from the Mayr type - note the very short propodeal spines but so has defleta.

The photomontage is of a worker from Namibia, collector Heather Campbell (Tree 160).
This appears a good match for the Mayr description and Arnold's note. Appears to match the type of calens (above).
