ulugurensis (Cremastogaster ferruginea Forel, var. Ulugurensis n. var., Forel, 1911d: 369, worker; Santschi, 1914b: 86, queen & male) Uluguru Mountains and Morogoro, collected by Zimmer - http://www.antweb.org/specimenImages.do?code=casent0908507
Forel (1911d) noted ulugurensis as similar to but darker than harrarica; TL 3.5-5.2 mm; reddish brown, with the gaster more yellow red, legs and antennae brown; head subopaque and very densely longitudinally striate; pronotum finely reticulo-punctate and coarsely reticulate or rugose with several irregular fossae. This appears an almost exact match for hararica.
