return to key {link to the Hymenoptera Name Server} Type location Cameroun (Cremastogaster inconspicua nov. spec., Mayr, 1896: 246, worker & queen), collector Y. Sjöstedt - see below

Worker and queen only described (see Bolton, 1995) .


Mayr's (1896) description is at {original description}.


Translation by Hauke Koch - Worker. TL 3.5-3.6 mm. Brown or more red brown, petiole and abdomen more or less yellowish-brown, the mandibles and the funiculi dirty-yellowish-red, the tarsi clayish-yellow. The erect, moderately long pilosity is very sparse on the dorsum, on the ventrum more pronounced, the scape, the femur (besides some long hairs at the base) and the tibia have the same hairs; the short close-fitting pubescence is rather sparse, richer on the tibiae and the scape, on the latter also somewhat longer and slightly erect. The shiny mandibles are finely and shallowly longitudinally striated, partly smooth, with few points, at the base denser and sharper striated. The head is rounded-quadratic, wider than the thorax, not very shiny, densely and finely longitudinal, at the distal part transversely striated, with sparse points bearing a hair, the middle of the frons and the following median part of the vertex rather shiny and more or less smooth or slightly streaky. The frontal clypeal margin is not depressed. The frontal carinae weakly developed. The scape of the 11-segmented antennae almost but not quite reaching the occipital margin, the 2-4th funicular joint slightly longer than wide, the 5-7th very conspiciously longer than wide, the last three joints forming a conspicious club. The eyes lie in the middle of the sides of the head. The not very shiny alitrunk is finely longitudinally striated, the sides of the pronotum are more shiny, particularly below, and more or less smoothened, the declining area of the propodeum is very shiny and smooth. The alitrunk is rather short, rounded at the front and very conspiciously wider at the back, between mesonotum and propodeum very constricted. The pronotum to both sides with a not very conspicious rounded hump. The mesonotum with a very conspicious weakly convex disc without median keel, laterally not emarginated, from the pro-mesonotal suture to the metanotal suture rather evenly arched. The spines of the propodeum are straight, rather divergent, circa half as long as the width of the basal area posteriorly. The shiny pedicel has a very subtle wrinkled sculpture, the petiole is almost quadratic, insignificantly longer than wide, anteriorly rounded to both sides, posteriorly truncated, the lateral margins arched, the maximal width of the segments is in or in front of their middle; the postpetiole has a moderately sharp longitudinal groove. The shiny gaster with very subtle shagreening or scaly and with sparse, hair-bearing points. In the species-overview of the workers of the African species in my work "Afrikanische Formiciden" in the "Annalen des k. k. naturhistorischen Hofmuseums in Wien" 1895 page 137, when determining this new species, one gets to No 13a. These species have a reverse trapezoid petiole, in which the frontal margin proceeds to both sides, laterally from the articulation with the alitrunk, with a small peduncle, in a more or less transverse direction; whereas in the new species the frontal margin proceeds to both sides, laterally from the small peduncle, immediately inclined to the back and sides and proceeding into the lateral margin.
