| 3:56a | [Arachnida • 2024] Harmonicon candango • A New Species of Harmonicon F. O. Pickard-Cambridge, 1896 (Araneae: Mygalomorphae: Dipluridae), from central-west Brazil and Redescription of H. rufescens
Abstract A new species of Harmonicon F. O. Pickard-Cambridge, 1896, is described from the Cerrado biome in Central-West Brazil, representing the first non-Amazonian and the southernmost record for the genus. Furthermore, we present a new diagnosis of the genus, expanding its original diagnosis, and redescribe its type species, Harmonicon rufescens F. O. Pickard-Cambridge, 1896, based on an adult female specimen from the same biogeographical area of its type locality. Key Words: Amazon region, biodiversity, Brasília, Cerrado biome, Diplurinae, Lyra, Pará
Harmonicon candango sp. nov. Diagnosis: Harmonicon candango sp. nov. can be separated from all other Harmonicon by its lyra composed of setae curved from its base and bearing spatulate tips (Figs 2H, 3C) (vs. setae with strongly curved, thin, and acute tips) (e.g., Fig. 1C; Maréchal and Marty 1998, fig. 2A, B; Drolshagen and Bäckstam 2011, fig. 6). Males of H. candango sp. nov. resemble H. oiapoqueae by the dark colour and the similar pedipalp bulb profile, with a low hump at the bulb near the basis of embolus, which is not crooked and almost straight (Fig. 2B, D). They may be recognised from those of H. oiapoqueae by the presence of the ventral setae near the retrolateral tubercle at metatarsus I (Fig. 2J), tibia I with retrolateral spur bearing ... Etymology: The specific epithet “candango” is a masculine noun in apposition used to designate the inhabitants of the city of Brasília, especially to the immigrants from Northeast Brazil who built the city.

| 8:31a | [Ichthyology • 2020] Trichomycterus vitalbrazili • A New Species of Trichomycterus (Siluriformes: Trichomycteridae) from the Rio Paraíba do Sul Basin, South-eastern Brazil
A phylogenetic analysis using fragments of two nuclear and two mitochondrial genes strongly supported sister group relationships between a new species and Trichomycterus albinotatus, corroborated by unique colour patterns of adult specimens and juveniles, and morphology of the autopalatine bone. The new species is distinguished from its closest congener, T. albinotatus, by details of the colouration and number of branchiostegal rays. Both the new species and T. albinotatus are endemic to the Rio Paraíba do Sul basin, in the Atlantic Forest of south-eastern Brazil, but occur in distant and disjunct areas. The new species, herein described, is endemic to the upper section of the Rio Grande drainage, a right tributary of the lower Rio Paraíba do Sul, an area situated in the Órgãos Mountain Range. Trichomycterus albinotatus is endemic to an area about 200 km across, in the upper section of the Rio Preto that drains the Itatiaia Massif. However, both species are only known from localities above 1100 m asl, suggesting that they cannot survive in ecological conditions at lower altitudes. This study indicates that efforts are necessary to provide more accurate data on the species diversity and distribution of Trichomycterus in the biologically diverse and endangered Atlantic Forest of south-eastern Brazil.

Trichomycterus vitalbrazili sp. nov. Vilardo, Diagnosis: Trichomycterus vitalbrazili is
distinguished from all other congeners except T.
albinotatus by the presence of a vertical row of dark
brown to black spots on the caudal peduncle end, often
coalesced to form a precaudal bar in live and preserved
specimens (Fig. 2A–B; vs. never a similar colour
pattern); two horizontal rows of white spots on the
flank in live juveniles (Fig. 3A–C; vs. never a similar
colour pattern); and medial margin of the autopalatine
nearly straight to slightly convex (Fig. 4A; vs.
concave). Trichomycterus vitalbrazili is distinguished
from T. albinotatus (Fig. 5A–B) by possessing diffuse
irregularly shaped dark brown blotches on the flank in
adult specimens (Fig. 2A–B; vs. well-delimited dark
grey to black, sometimes coalesced in larger specimens);
fins with dark brown spots in adults specimens (Fig.
2A–B; vs. without spots); and eight branchiostegal rays
(vs. seven) Etymology: The name vitalbrazili was given in
honour of Vital Brazil Mineiro da Campanha (1865–
1950), an important Brazilian biomedical scientist who
first discovered the polyvalent anti-ophidic serum,
successfully used to treat venomous snake bites, and
founded the Vital Brazil Institute, where the new species
was found.

Abstract A new species, namely Astioberotha coutreti sp. nov., of the thorny lacewing subfamily Paraberothinae, is described and illustrated from a complete individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar. Astioberotha coutreti sp. nov. preserves nearly all the diagnostic characters of this subfamily, and differs from the type species of the genus Astioberotha owing to the fore femur with one long basal spine and 34 additional smaller spines; protibia bearing five distal spines; probasitarsus with two spines on inner edge located near mid-length; forewing with numerous maculation spots; intra-RP crossvein between RP3 and RP4 present (4rp3-rp4). Astioberotha coutreti sp. nov. together with the recent description of several other Paraberothinae species from the mid-Cretaceous Burmese amber, are used to discuss the palaeobiogeography of the subfamily.

| 4:52p | [Entomology • 2025] Amblysellus tenochtitlanum • Urban Forests as Refuges for Resilient Species: A New Species of Amblysellus Sleesman (Hemiptera: Cicadellidae) from Central Mexico
Abstract Urban parks within large metropolises hold valuable resources broadly useful for insects and may even harbor previously undiscovered species. Such parks also offer excellent opportunities to engage urban residents in citizen science activities that may not only foster greater appreciation for nature but also lead to new scientific discoveries. An example, reported here, is a new grass feeding leafhopper species of the genus Amblysellus, A. tenochtitlanum sp. n., found through a citizen science workshop in urban forests of Mexico City and its surroundings. The morphology of the new taxon is extensively detailed and illustrated. An updated key to all known species of Amblysellus in Mexico is also provided. Data retrieved from the workshops were used to evaluate the conservation status of the new species and its congeners following IUCN criteria, using museum specimens and published literature. We discuss the importance of involvement between citizen scientists and academia for insect surveys not only to provide educational opportunities but also to yield new data relevant to the conservation of poorly known species.

Amblysellus tenochtitlanum Pinedo-Escatel, Blanco-Rodríguez, and Aponte-Mejia, sp. n. Etymology. This species is named for the main region where the Mexica (Aztecs) empire was distributed known as “Tenochtitlan”. After a century of expansion of Mexica domains, the city had become the most populated and richest area in Mesoamerica. Epithet based on the main distribution of organisms studied. Gender for the new taxa name is neuter.
