Tafaliscina Desutter, 1988 (Grylloidea Laicharting, 1781, Gryllidae Laicharting, 1781, Oecanthinae Blanchard, 1845, Paroecanthini Gorochov, 1986) are a Neotropical cricket clade with a remarkable morphological diversity. We study here their Brazilian representatives. We describe one new genus (Veredatrypa Campos n. gen.) and three new species from Cerrado and Caatinga, i.e., Veredatrypa rosai n. gen., n. sp., V. seca n. gen., n. sp. and V. fusca n. gen., n. sp., and two new species of Tafalisca Walker, 1869 from Amazon Forest, i.e., T. duckeana n. sp. and T. vestigialis n. sp. The new genus and the new species are mainly characterized by their male phallic complexes and forewings. An identification key of Tafaliscina Brazilian genera is provided, and the diversity of the subtribe is discussed in relation to the life habits and communication modalities of Tafaliscina genera.

Veredatrypa Campos n. gen.
Type species. — Veredatrypa rosai n. gen, n. sp.
Species included. — Veredatrypa rosai n. gen., n. sp.; Veredatrypa
seca n. gen., n. sp.; Veredatrypa fusca n. gen., n. sp.
Etymology. — Named after “Grande Sertão: Veredas”, a novel
written by the Brazilian novelist João Guimarães Rosa. Grande Sertão:
Veredas (in English, translated as The Devil to Pay in the Backlands)
is one of the masterpieces of Brazilian literature and one of the most
important novels in Portuguese language literature due to its style
and complexity. Grande Sertão: Veredas is also a Brazilian National
Park that protects a large fragment of Brazilian Cerrado, including
wetlands areas known as “veredas”. That Park is located in the same area
where the novel happened and is the type-locality of this new genus.
Distribution. — This genus is recorded for Brazilian open
forests as the Cerrado and Caatinga, in States of Minas Gerais,
Goiás and Ceará.
Diagnosis. — The genus is separated from the other genera of
Tafaliscina by the following characters: median ocelli very reduced, almost no discernible; DD with longitudinal lateral bands from
cephalic to caudal margin. Male: metanotum with two pairs of
projections, with cluster of bristles (absent in V. seca n. gen., n. sp.).
FWs with anal vein area slightly bulged dorsally, stridulatory file
surrounded by strong sclerotization, hv anterior region strongly
sclerotized. Male genitalia: MLophi triangular, with a pointed apex;
LLophi very short or absent; EctF strongly sclerotized, wide anteriorly, thin posteriorly, going along MLophi, apex folding dorsally,
connecting to the apex of MLophi; endophallic apodeme bifid.
Female: ovipositor short than cerci, with two lateral protuberances
in dorsal and ventral views. Female genitalia: copulatory papilla
distal half constricted, without furrow ventrally.
Veredatrypa rosai n. gen., n. sp.
Etymology. — Name after the Brazilian novelist João Guimarães
Rosa, author of the novel “Grande Sertão: Veredas”.
Veredatrypa seca n. gen., n. sp.
Etymology. — The word “seca” means “dry” in Portuguese, referring to the climatic conditions of the region where this species was
collected. The name is a noun in apposition.
Veredatrypa fusca n. gen., n. sp.
Etymology. — From Latin, “fusca” means “dark”. This species
is darker than the other species of the genus.
Tafalisca duckeana n. sp.
Etymology. — Referring to “Reserva Florestal Adolpho Ducke”,
a forest area managed by the Instituto Nacional de Pesquisas
da Amazônia (INPA), where this species was discovered.
Tafalisca vestigialis n. sp.
Etymology.— From Latin, “vestigialis” means “vestigial”, referring
to the vestigial stridulatory file of this species.
