| 12:36a | [Botany • 2022] Thismia mantiqueirensis (Thismiaceae) • A New Species of Brazilian Atlantic Rainforest
Abstract In the present study, we describe and illustrate Thismia mantiqueirensis, a new mycoheterotrophic species belonging to the subgenus Ophiomeris, section Ophiomeris, from the Altomontane Dense Ombrophilous Forest in Mantiqueira mountains, southeast Brazil. We provide the description, taxonomic, ecological, and conservation comments, as well as images and illustrations of the new species. Keywords: State of São Paulo, Altomontane Dense Ombrophilous Forest, Mycoheterotrofic, Ophiomeris, Mantiqueira mountain, Monocots
 Thismia mantiqueirensis Engels & E.C.Smidt sp nov. Etymology:— The specific epithet refers to the Mantiqueira mountains, where the species was discovered.

| 9:16a | [Entomology • 2022] Leioproctus zephyr • An Oligoletic New Bee Species (Hymenoptera: Colletidae) with A Distinctive Clypeus
Abstract A new species Leioproctus zephyr (Hymenoptera: Colletidae) is described from both sexes. Leioproctus zephyr sp. nov. is remarkable in featuring a large longitudinal ridge on the clypeus. This diagnostic morphological feature present in both sexes, along with various other distinctive characters including the male genitalia, female hind-tibial spur, and glossa morphology, clearly distinguish this species from all other Leioproctus. Along with these unique traits, L. zephyr cannot be classified into any of the existing subgenera of Leioproctus, sharing some, but not all, of the characters of the subgenera Ceratocolletes, Charicolletes, Protomorpha and Odontocolletes. DNA barcoding with the CO1 gene confirmed the sexes belonged to the same species and it did not match any previously barcoded species. This species is restricted to native vegetation remnants in the southwest Western Australian biodiversity hotspot, and is highly specialised, foraging only on a few species in the genus Jacksonia (Fabaceae). The unusual clypeus may be an adaptation for foraging on the keeled papilionaceous flowers. The limited number of sites this species has been collected from and its oligolectic diet suggest L. zephyr should be considered to be a species of conservation concern. Further taxonomic research is required to determine the phylogenetic position of this unusual Leioproctus. Keywords: Australia, biodiversity hotspot, colletid, DNA barcoding, new species, specialist
Leioproctus zephyr Prendergast, sp. nov. Etymology: The species is named after the author’s beloved Maremma dog, Zephyr. The name “zephyr” is proposed as a noun in apposition. Kit S.

| 5:04p | [Mammalogy • 2023] Cheracebus aquinoi • A New Species of Titi Monkey, Genus Cheracebus Byrne et al., 2016 (Primates: Pitheciidae), from Peruvian Amazonia
 Abstract The subfamily Callicebinae is composed of 35 recognized living species that are grouped into the genera, Callicebus, Plecturocebus, and Cheracebus. In this study we assess the taxonomic status of the population of Cheracebus from the Nanay-Tigre interfluvium in Peruvian Amazonia, based on morphological (cranial and pelage) and molecular (mitochondrial DNA) evidence. Following the integrated assessment of the evidence, we conclude that specimens from the Nanay-Tigre interfluvium comprise a distinct lineage at the species level. It is easily distinguished from the other species of the genus, including C. lucifer to which the new species was considered to belong so far, by, among other characters, overall Reddish-brown pelage; crown intense reddish brown; Cream-colored collar, like a bow tie, with a band that does not extend laterally. The description of a new species of Cheracebus is not unexpected since other new species of titi monkeys have been described in recent years and there are several candidate species awaiting validation of their distinction. As such, we anticipate that in the next few years several taxonomic changes will be proposed in order to reveal a classification that mirrors the real species diversity of the subfamily Callicebinae.
