A diminutive ground-nesting species that also inhabits downed wood and acorns and nuts on the ground.
|At a Glance||• Polygynous|
Longino (2003) - In Costa Rica Crematogaster minutissima is uniquely characterized by the combination of (1) yellow coloration; (2) humeral setae of mesosomal dorsum long, flexuous, and longer than any other mesosomal setae; (3) relatively short propodeal spines; and (4) relatively compact promesonotum. Similar Costa Rican species are Crematogaster wardi and Crematogaster flavomicrops.
Crematogaster minutissima and Crematogaster missouriensis (see also Creighton 1939) are small yellow ants with short, upturned propodeal spines, promesonotal setae in three ranks decreasing in length from front to back, dorsal face of petiole subquadrate, about as wide as long, scapes just reaching margin of vertex, and tibiae lacking the extremely long setae of Crematogaster sumichrasti and Crematogaster flavosensitiva. It occurs throughout the southern United States and south to northwestern Costa Rica. Within these parameters there is variation in overall size, degree of development of the anteroventral petiolar and postpetiolar teeth, strength of punctate sculpture on katepisternum and side of petiole, and queen size. This variability is the basis for the subspecies missouriensis from the central United States and the now synonymized smithi (= missouriensis) from the southwestern United States.
Crematogaster cubaensis and its synonym barbouri, restricted to Cuba, are similar to the population of small minutissima in Florida, but the promesonotum has a scruffy appearance, with abundant erect setae that are not clearly arranged in three ranks. Crematogaster wardi is a parapatric version of minutissima that occurs in wet forest habitats in Costa Rica. It has longer scapes, the promesonotum is longer and flatter, the three ranks of setae on the promesonotum are more nearly equal length, the propodeal spines are longer and directed posteriorly, and the dorsal face of the petiole is distinctly longer than wide.

|Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.|
Longino (2003) - The one Costa Rican record of this species is from Santa Rosa National Park in the seasonally dry northern Pacific lowlands. I collected a series of nocturnal foragers from low vegetation in the second growth forest around the administrative headquarters. In the USA the species is known to occur in a variety of habitats across the southern and central USA, nesting in dead wood on the ground. Where there is moist leaf litter they may be collected in Winkler samples of sifted leaf litter.
MacGown (2006) examined ants nesting or occupying hickory nuts in the Tombigbee National Forest (Ackerman Unit), Mississippi. While several hickory species were present, ants were found almost exclusively in the nuts of Carya glabra. Four colonies of Crematogaster minutissima were found, with 464 workers and 4 queens, 78 workers and 3 queens, 6 workers and 5 workers and 10 queens. This suggests that colonies contain less than a thousand workers, are likely monodomous (because most nuts contains queens) and polygonous (because multiple queens were always present in the nest). While C. minutissima colonies were found with relative ease and in large numbers in the hickory nuts by MacGown (2006), the species was otherwise only rarely encountered in the Tombigbee National Forest when using pitfall and other collecting methods.
