IBOTYPORANGA MELLO-LEITAO, 1944

Ibotyporanga Mello-Leitao, 1944a: 6 (type species by original designation Ibotyporanga naideae Mello-Leitao, 1944 ; examined).

DIAGNOSIS/DESCRIPTION: See diagnosis and description of single known species below.

GENERIC RELATIONSHIPS: Ibotyporanga seems very close to Gertschiola , with which it shares the long thin procursus and especially the proximal part of it, which is characteristically bent in a ventral direction and then makes a turn. The two genera are also almost identical in habitus.

DISTRIBUTION: Widely distributed in central and northern Brazil.
