| Crematogaster manni|
Nothing is known about the biology of Crematogaster manni.
Buren (1968) - C. manni may be considered as something of a link between Crematogaster sanguinea and Crematogaster ashmeadi, but may be easily distinguished from either. The heavy antennae, wide epinotum, and shape of petiole show it to be related to sanguinea, but manni differs in having a more flattened promesonotal dorsum with strong humeri, and the ashmeadi-type epinotal spines. The long antennae and stronger sculpture of the thorax as well as other differences separate it from ashmeadi. The pro-mesonotal outline of ashmeadi is more flattened, the humeri not as developed, and there is a definite mesonotal declivity, unlike this new species.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Length about 2.5 mm.
Head, excluding mandibles, broader than long, with sides convex and posterior border excised slightly or straight in the middle, head a little broader in front of the eyes than behind. Scapes surpassing hind corners by about two diameters, the antennae noticeably large and heavy in proportion to the head. Humeri of pronotum strong, often marked by striae. Promesonotum convex in profile, especially in front, but much less so than in sanguinea and its close relatives. No mesonotal declivity. Meso-epinotal impression moderate. Epinotum very wide and with wide interspinal distance. Spines of the ashmeadi shape, subparallel or parallel and with convex outer sides, usually moderate in length, however, not short as in ashmeadi. Petiole with, somewhat rounded sides seen from above, in profile thicker at rear than in front as in sanguinea. Hemilobes of postpetiole wide, rounded; sulcus of moderate depth. Postpetiole inserted a little farther back on dorsum of gaster than is usual in most species.
Clypeus merely roughened in the middle, laterally with converging striae. Genae and front striato-punctate, the genal sculpture carried well past the eyes. Vertex, occiput, and corners smooth and shining. Mandibles also weakly striate and shining. Front of pronotum punctate and irregularly roughened. Pronotal dorsum with faint striae or weakly striato-punctate, subopaque. Pronotal sides faintly striato-punctate, subshining. Mesonotum finely striate or striato-punctate. Mesopleura punctate. Metapleura shining above, striato-punctate below. Base of epinotum with faint irrregular rugae, declivity smooth and shining.
Pubescence short and appressed on all parts except scapes, there rather long and suberect. Erect hairs long on thorax, only one or two on each shoulder and one or two at rear of mesonotum. On gaster a few near posterior borders of the segments.
Head and thorax dark brown. Gaster black.
Holotype worker and fourteen paratype workers from Herradura, Cuba. W. M. Mann, collector. Holotype and most of the paratypes to be returned to the National Museum. I will retain three paratypes.
This species is named in honor of its collector, the late distinguished scientist, Dr. William M. Mann.
