Etymology — From the Brazilian Tupi Indian language, which means “very small”, considering these are among the smallest
Theraphosidae
. The gender is neuter.
Typespecies —
Catumiri petropolium
n. sp.
Diagnosis — Differs from other Ischnocolinae genera but resembles
Oligoxystre
by the labium being much wider than long and by the reduced number of cuspules on the labium and gnathocoxae. Differs from
Oligoxystre
by the anterior tarsal scopula being divided by a longitudinal band of setae (
Fig. 15
), spermathecae receptacles each with one apical terminus (
Figs. 9
,
11, 12
,

) and by the presence of a row of teeth on the prolateral margin of the tarsal claws of males (
Fig. 3
). The genus
Cenobiopelma
differs from
Catumiri
n. gen.
by having a wide clypeus and by the absence of a well developed anterior process in the gnathocoxae.
Description — Chelicerae without rastellum. Thoracic region slightly recognizable. Eye tubercle slightly elevated, wider than long. Anterior eye row procurved, posterior recurved or straight. Thoracic furrow straight. Labium wider than long with few cuspules (0–10). Gnathocoxae with a distinct anterior lobe with 5 to 44 cuspules on the internal basal angle. Sternum oval or rounded, sigillae very close to the sternal margin, posterior largest. Metatarsi with ventral scopula, less than the half of metatarsus I scopulated, IV with scopula restricted to the apical portion. Tarsal scopula I–IV divided by a longitudinal band of setae, except
C. petropolium
that have tarsal scopulae I–II undivided and III–IV divided. Paired tarsal claws of males with teeth on the prolateral margin. Third tarsal claw absent. Claw tufts well developed. Posterior median spinnerets with one segment, very short. Posterior lateral spinnerets threesegmented, apical article digitiform. Spermathecae paired, longer than wide, with spherical termini. Male palpal bulb with a thin, straight or curved embolus. Cymbium bilobate, longer than wide. Tibial spur present, except in
C. petropolium
.
