FEMALE. Described in Lopes (1935), redescribed and illustrated in Lopes (1976).

Distribution (Neotropical). Brazil (Ceará, Espírito Santo, Federal District, Maranhão, Goiás, Mato Grosso, Mato Grosso do Sul *, Minas Gerais, Pará, Paraíba, Pernambuco, Rio de Janeiro, Rio Grande do Norte, São Paulo).

Comments. Titanogrypa   (C.) larvicida   closely resembles T. (C.) alvarengai   , T. (C.) albuquerquei   and T. (C.) pedunculata   , all of which have a vesica with an unpaired projection at the base ( Figure 4 View Figure 4 (e)). However, the projection is sclerotised in T. (C.) larvicida   whereas it is membranous in the other species. This species also differs from the other congeneric species by having a vesica with the distal lobes conspicuously ornamented with spines ( Figure 4 View Figure 4 (d,e)).

Additionally, in the present study T. (C.) larvicida   had its geographic distribution updated for the Brazilian territory. From the examined material, field data and literature records, the presence of this species was confirmed for the Brazilian states of the Midwest, North, Northeast and Southeast regions. Finally, we highlight the presence of T. (C.) larvicida   in the Caatinga domain, a type of dry and open forest exclusive in the northeastern Brazil, where this species was attracted by three types of bait: rotten bovine spleen, decomposing fish and fresh human faeces.
