| 2:52a | [Entomology • 2022] Leptogenys elzasoares • Review of the Leptogenys unistimulosa Species Group (Hymenoptera: Formicidae) with the Description of A New Amazonian Species
ABSTRACT Leptogenys elzasoares new species, is described from workers and a male collected near Manaus in the Brazilian Amazon. The worker is recognizable by the presence of 12 chaetae (stout setae) on the clypeal median lobe, the straight mandible, and its bicolored body; the head and mesosoma are black while the gaster is brightly ferruginous. For the first time, the males of L. bohlsi Emery, 1896, L. unistimulosa Roger, 1863, and L. parensis Lattke, 2011 are described. A new key to the males of the unistimulosa species group is provided, and the key to workers of Lattke (2011) is updated to include the new species. Finally, we also report new records of L. parensis from French Guiana, expanding the known distribution by over 780 km northwest. Keywords: Ants; Neotropical; Ponerinae; Taxonomy
Leptogenys elzasoares new species Worker diagnosis: Head weakly rugulose in full-face view. Mandible mostly straight in full-face view, weakly widening apicad. Median clypeal lobe with 12 chaetae (= stout setae). Eye large, occupying one-third lateral cephalic margin. Hypostomal tooth not as long as mandibular width. Mesonotum wider than long. Propodeal dorsum transversely striate. Petiolar node with an acutely pointed posterior spine. Head, mesosoma and petiole black, antenna, legs and gaster brightly ferruginous. Etymology: This species is named, in apposition, after Elza da Conceição Soares (1930–2022), one of the greatest Brazilian singers of all time. Named the voice of the millennium, she was a powerful voice for social and racial justice, and women’s rights. Our beloved Elza has gone to rest, but her voice will forever echo in our hearts.

| 3:07a | [Botany • 2022] Begonia tuanii (Begoniaceae, sect. Platycentrum) • A New Species from Lao Cai Province, North Vietnam
Abstract Begonia tuanii from Lao Cai Province of Vietnam is described and illustrated. The habit of B. tuanii is mostly similar with B. fordii, but it can be distinguished by its bracts glabrous (vs. pilose) abaxial surface, larger outer tepals of staminate flower by 25–40 × 24–35 mm (vs. 6–8 × 5–77 mm) that are whole glabrous (vs. abaxially hairy), inner ones 20–35 × 10–20 mm (vs. 5.6–7.5 × 3–4 mm) and glabrous (vs. pilose) ovary. Referring to the IUCN of Nature criteria, B. tuanii is proposed to be Endangered (EN D). Keywords: Asia, biodiversity, endemism, Indochina, Limestone, Sect.
