Holotype worker of
Prionopelta menininha
(Brazil, Bahia). A. Full-face view; B. Lateral view; C. Dorsal view. Specimen: DZUP549778.
Etymology.
The species is named in honor of Maria Escolástica da Conceição Nazaré, also known as “Mãe Menininha do Gantois”, a descendant of the Nigerian Yoruba royalty enslaved in
Brazil
, and one of the most prominent Brazilian
iyalorixá
(spiritual leader of the Afro-Brazilian religion
Candomblé
). The species name is a recognition to the Afro-Brazilian religions and community, and to the state of
Bahia
, from where
P. menininha
is mainly known. The specific epithet is a Portuguese noun in apposition, indeclinable in accordance to articles 31.2.1 and 31.2.3 of the International Code of Zoological Nomenclature.
Distribution (
Fig. 35B
).
The species is known from northeastern and southeastern
Brazil
, in the states of
Bahia
,
Ceará
, and
Minas Gerais
.
Comments
. This species can be confused with
P. punctulata
and
P. tapatia
because of the presence of eleven antennomeres. However, morphological features allow the separation of these three species.
Prionopelta punctulata
has the clypeus strongly projecting medially and the subpetiolar process with margins apically convergent, in contrast to
P. menininha
. It can be distinguished from
P. tapatia
mainly by the obtuse posteroventral angle of the subpetiolar process, acute in
P. tapatia
. Also,
P. menininha
has the petiolar node and the first gastral segment wider and longer than
P. tapatia
. Finally, so far,
P. tapatia
is a species endemic to
Mexico
.
Natural history.
Most specimens are known from pitfall and soil samples collected in dry forest areas.
