Austrotinodes lenti Leandro Lourenço Dumas & Wagner Rafael M. de Souza 2017, sp. nov.
No full textAustrotinodes lenti sp. nov. urn:lsid:zoobank.org:act:3F6DE9B2-F30D-4178-8CD3-AD86 FF898813 Figs 10, 14 Diagnosis Austrotinodes lenti sp. nov. resembles A. chihuahua Flint & Denning, 1989 in the structure of the moderately elongate club-like intermediate appendages with 3 spine-like setae near its apex. This species is easily diagnosed by the unusual bifid shape of the lateral process of the phallic apparatus, with a short, stout dorsal branch bearing 3 spines at its anterior margin, and a long, slender ventral branch with an apical, very elongate rugose, spine-like seta. Etymology This species is dedicated to the Brazilian medical zoologist and entomologist Herman Lent, who was born in Rio de Janeiro in Rio de Janeiro state in 1923 and died in 2004. Herman Lent dedicated himself to studying the vectors of Chagas’ disease, becoming one of the greatest triatomine specialists in the world, and publishing more than 200 scientific papers.

Austrotinodes absaberi Leandro Lourenço Dumas & Wagner Rafael M. de Souza 2017, sp. nov.
No full textAustrotinodes absaberi sp. nov. urn:lsid:zoobank.org:act:231301EA-9ECA-4C46-AFAB-3FE6ED93DFC8 Figs 1, 14 Diagnosis Austrotinodes absaberi sp. nov. is most similar to A. gusmaoi sp. nov., A. donagrazielae sp. nov. and A. taquaralis, resembling these species in the elongate, upwards curved intermediate appendages with 3 apical spine-like setae. It differs in that the apical portion of the phallus has a long, slender posterolateral spine, absent in the other species. Furthermore, the intermediate appendage in A. absaberi sp. nov. and A. gusmaoi sp. nov. lacks a basoventral seta. Other differences distinguishing A. absaberi sp. nov. from related species are the shape of the phallic guide, which is smaller and strongly arched in the species described here, and the more elongate preanal appendages when compared with those of A. gusmaoi sp. nov. The differences among these species are relatively minor, and they are here placed informally in the taquaralis Group based on: (1) the elongate, upwards curved intermediate appendages with 3 apical spines; (2) phallus with lateral process elongate, bifid, bearing an elongate and more robust dorsal branch and a short and slender ventral branch. Etymology The species is dedicated to the Brazilian biogeographer, geologist and environmentalist Aziz Nacib Ab’Saber, who was born at São Luiz do Paraitinga in São Paulo state in 1924 and died in 2012. Aziz Ab’Saber was the first person to classify scientifically the Brazilian and South-America territory in morphoclimatic domains. He also contributed to the “Pleistocene Refuge Hypothesis”, an attempt to explain the distribution and diversification of Neotropical taxa as a result of their isolation in forest fragments during glacial periods.

This species can be distinguished from all other members of the taquaralis Group by the posterior margin of sternum IX strongly convex, the preanal appendages with crenulated margins and by the very elongated lateral lobes of inferior appendages. Additionally, the more robust phallic guide and the presence of a tuft of small mesodorsal microsetae at intermediate appendages are useful characters to diagnose A. gusmaoi sp. nov. Etymology The species is dedicated to the Brazilian priest and inventor Bartolomeu de Lourenço Gusmão, who was born at Santos in São Paulo state in 1685 and died in 1724. Bartolomeu de Gusmão was the first Brazilian inventor and scientist, famous for the creation in 1709 of the hot air balloon.

No full textAustrotinodes cruzi sp. nov. urn:lsid:zoobank.org:act:DE6F6AE4-3650-49DC-B099- DEAF 33FE4AD7 Figs 6, 14 Diagnosis Austrotinodes cruzi sp. nov. can be distinguished from all other species of the genus by the unusual shape of the intermediate appendages, which are very elongate and boomerang-like, and by the phallus, which has a short lateral process, hood-like when viewed laterally. Etymology The species is dedicated to the Brazilian physician, scientist, epidemiologist and bacteriologist Oswaldo Gonçalves Cruz, who was born at São Luiz do Paraitinga in São Paulo state in 1872 and died in 1917. Oswaldo Cruz was the mentor in an important sanitary campaign in Rio de Janeiro, which aimed at controlling the bubonic plague, yellow fever and smallpox. These diseases were raging all over the city, at the turn of the 20th century, decimating the population. He also was the founder of an important research institute, named after him.

However, A. chagasi sp. nov. can be easily distinguished from A. bracteatus by its more elongate and crenulated preanal appendages, and especially by the general structure of the phallus, which has a branched lateral process, with a long finger-like ventral branch, whereas in the formerly described species the lateral process is shorter and not branched. Etymology The species is dedicated to the Brazilian sanitary physician, scientist and bacteriologist Carlos Justiniano Ribeiro Chagas, who was born at Oliveira in Minas Gerais state in 1879 and died in 1934. Carlos Chagas described, in 1909, the disease named after him (Chagas disease) as well as the etiological agent (Trypanosoma) and the vector (hematophagous insects, Triatoma infestans Klug, 1843). The deed of discovering all the links in the epidemiological chain of an infectious disease was absolutely unprecedented in the history of medicine.
