Crematogaster (Oxygyne) brevarmata Forel - new status

Type location Zaïre (Cremastogaster Santschii For. v. brevarmata n. var., Forel, 1915c: 337, worker & male; Santschi, 1930a: 65, queen) collected at Kondué, by Luja - see below .

The queen of lujae is totally different to the type queen of margaritae. and probably is the queen of brevarmarta. See Crematogaster lujae (Cremastogaster (Oxygyne) Margaritae Em. r. Lujae n. stirps, Forel, 1913b: 325, queen) also from Zaïre, Kondué, by Luja - see http://www.antweb.org/specimenImages.do?code=rmcaent000017764

Forel's (1915c: 337) description of brevarmata (Cremastogaster Santschii For. v. brevarmata n. var. is -
TL 2.9-3.4 mm; propodeal spines much smaller than type, length less than half the width between their bases; base also more slender. Mesonotum slightly convex anteriorly and obliquely truncate posteriorly, from above the truncated part is tranversely slightly concave. Head not as narrow but without concavity behind the mid-line. Scape shorter than clymene, not passing the occiput, as the type. Rest as the type.
MALE - TL 1.9-2.4 mm; mandibles narrow with a single apical tooth; scapes less than twice as long as their width; funiculus segments, except the apical, narrower than long; propodeum unarmed; wings lightly tinted with rust-brown; postpetiole scalloped behind. Body blackish brown with appendages brown.
Collected at Kasai, Kondué, Zaïre, by Luja.

From Santschi (1935a): Compared with the Crematogaster margaritae type, not only does brevarmata have a flatter profile to the alitrunk, with shorter propodeal teeth, but it is larger, TL 2.9-3.4, and has a shorter scape. The frontal notch is missing or reduced; the clypeus noticeably convex, with an arcuate anterior margin. Propodeal spines short and set quite wide apart. Postpetiole deeply divided. The specimen below has marked very fine sculpturation on the head and alitrunk and so is semi-matt not smooth and shiny.

Santschi (1930a: 60) wrote only that the queen (not previously described) - TL 4.3-4.5 mm; not differing from margaritae other than the head being narrower; colour as the worker. Belgian Congo: Kasai, Kondue (E Luja) workers and queen.
