Diagnosis.
Pterinopelma
resembles
Lasiodora
C. L. Koch 1850
,
Vitalius
and
Nhandu
Lucas 1983
by the combined absence of accessory prolateral keels and presence of prolateral superior, prolateral inferior, retrolatral and apical palpal keels in males (
Figs 1
–3, 7–9); and by the spermathecae short, separated by a heavily sclerotized short area in females (Figs 6, 13). Both sexes are distinguished from those of
Lasiodora
by the absence of stridulatory hairs on the prolateral coxae. From
Nhandu
and
Vitalius
the males are distinguished by the presence of denticles in the prolateral inferior keel (Figs 3, 9) and the weakly developed or absent subapical keel (
Figs 1
–3). Females can be distinguished from
Nhandu
by the absence of long setae on the carapace and from
Vitalius
either by the presence of uticating hair
type
III on the abdomen (
P. sazimai
sp. nov.
), or by having a sternum wider than long (
P. vitiosum
) (Fig. 5).

Redescription.
Carapace slightly longer than wide, cephalic region slightly raised to clearly raised, convex. Cephalic and thoracic striae shallow or deep. Fovea straight, shallow (

P
.
vitiosum
) or narrow. Anterior eye row procurved, posterior slightly recurved. AME rounded, ALE, PLE and PME oval. Labium subquadrate, slightly wider than long, with numerous (90–155) cuspules on its anterior third. Maxila subretangular, anterior lobe distinctly produced into a conical process, inner angle bearing numerous cuspules (100–200). Sternum longer than wide (
