| 3:35a | [Herpetology • 2025] Hemiphyllodactylus laowozhenensis • A New Species of Hemiphyllodactylus (Squamata: Gekkonidae) from western Yunnan, China
Abstract A new species of gekkonid, Hemiphyllodactylus laowozhenensis sp. nov., is described based on three specimens from Lushui City, Yunnan, China. The new species can be distinguished from its congeners by a significant genetic divergence of greater than 4.8% in the mitochondrial ND2 gene and a combination of the following characters: maximum SVL of 38.5 mm; 10 or 11 chin scales; enlarged postmentals; 6 circumnasal scales; 2 or 3 internasal scales; 8 or 9 supralabial scales; 8 or 9 infralabial scales; 15 or 16 dorsal scales; 9 ventral scales; a manual lamellar formula of 3-4-4-4 and a pedal lamellar formula of 3(4)-4-4-4; 26–28 precloacal and femoral pore-bearing scales contiguous in males; 1–3 cloacal spur on each side; a dark postorbital stripe extending to at least base of neck; dorsolateral light–colored spots on trunk present; dark ventrolateral stripe on trunk present; dark dorsal transverse blotches present; and a dark and brown postsacral mark bearing anteriorly projecting arms. Key Words: Hemiphyllodactylus laowozhenensis sp. nov., integrative taxonomy, Lushui City, molecular phylogeny, slender gecko
Hemiphyllodactylus laowozhenensis sp. nov. Diagnosis: Hemiphyllodactylus laowozhenensis sp. nov. can be distinguished from its congeners by the combination of the following characters: maximum SVL of 38.5 mm; 10 or 11 chin scales; enlarged postmentals; 6 circumnasal scales; 2 or 3 internasal scales; 8 or 9 supralabial scales; 8 or 9 infralabial scales; 15 or 16 dorsal scales; 9 ventral scales; a manual lamellar formula of 3-4-4-4 and a pedal lamellar formula of 3(4)-4-4-4; 26–28 precloacal and femoral pore-bearing scales contiguous in males; 1–3 cloacal spur on each side; a dark postorbital stripe extending to at least base of neck; dorsolateral light–colored spots on trunk present; dark ventrolateral stripe on trunk present; dark dorsal transverse blotches present; and a dark and brown postsacral mark bearing anteriorly projecting arms. Etymology: The scientific name “laowozhenensis” is derived from its type locality Laowo Town, Lushui City in Yunnan province. We suggest Laowo Town Slender Gecko in English and “老窝镇半叶趾虎 (Lǎo Wō Zhèn Bàn Yè Zhǐ Hǔ)” in Chinese.

| 9:40a | [Entomology • 2025] Tigridania magdalenae • A New Trasandean Species of the Genus Tigridania Kaye, 1918 (Lepidoptera: Erebidae: Arctiinae) from Colombia
During curatorial work at the Entomological Collection of the Universidad de Antioquia (Medellín, Colombia), we discovered a recently collected pair of Euchromiina in copula (Fig. 1B) in the department of Antioquia, Colombia (Fig. 1A). It was a large and robust species, with translucent wings and a striking yellow and red abdomen. This species resembled Autochloris thyestes Druce, 1883, described from Ecuador, but certain details and characteristics suggested a more complex situation. After reviewing recent literature, we found the revision of the genus Tigridania Kaye, 1918 by Grados & Ramírez (2021). The genus Tigridania is monotypic, containing only the type species Tigridania quadricincta Kaye, 1918, described from the Rio Ucayali in the upper Amazon. The species Isanthrene flavizonata Gaede, 1926 which is also a large and robust species with translucent wings, was synonymized with T. quadricincta, by Grados & Ramirez (2021). However in T. quadricincta the abdomen is creamy-yellow with broad black bands and a black tip, markedly different from our species. On the other hand, the male genitalia and secondary sexual characteristics are very similar to those of the type species. Therefore, we have decided to describe it below as a new species, under the name Tigridania magdalenae sp. nov.  Tigridania magdalenae sp. nov.
