| 2:06a | [Entomology • 2024] Panolcus filirostris • A second species of the Genus Panolcus Gerstaecker 1860 (Coleoptera: Curculionidae: Molytinae: Cryptorhynchini) from French Guiana and Suriname with Taxonomic Changes in Cryptorhynchini
Abstract A second species of the genus Panolcus Gerstaecker, 1860 (Coleoptera: Curculionidae: Molytinae: Cryptorhynchini) from French Guiana and Suriname is described and compared with Panolcus scolopax Gerstaecker, 1860. Diagnostic characters and images are provided to facilitate identification. Adults were collected in a fruit of Duguetia surinamensis R.E. Fr. (Annonaceae). The genus Panolcus is transferred from Aedemonina (Cryptorhynchini) to Cryptorhynchina (Cryptorhynchini). The type species of Thrasyomus Pascoe, 1880 is here designated as Thrasyomus tumens Pascoe, 1880 and the species Thrasyomus uniformis Champion, 1905 is transferred from the genus Thrasyomus to Eubulus Kirsch, 1869 as Eubulus uniformis (Champion, 1905), new combination.

Panolcus filirostris Anderson, new species Diagnosis: Body length 10.8–11.0 mm in females, 9.5–9.8 mm in males, width 5.0–5.5 mm in females, 4.8–5.0 mm in males. Rostrum in female about twice as long as elytra, apex of rostrum reaching far beyond apex of elytra (by almost length of elytra) when in repose, of male, reaching to level of posterior margin of mesocoxae. Pronotum very strongly tubulate anteriorly in female, less so in male. Femora and tibiae proportionally slenderer in both sexes (although slightly less so in male), profemora about 4 x as long as width at base, protibiae about 7–8 x as long as maximum width. Protarsus with tarsomere 1 longer than tarsomeres 2–5 in female, shorter than tarsomeres 2–5 in male. Aedeagus with lateral margins subparallel, each with acute angle (but no tooth) at point of constriction. Robert S. Anderson. 2024.

| 2:36a | [Entomology • 2023] Anisandrus montanus, A. phithakpa, A. uniseriatus, etc. • New Species and newly recorded species of Anisandrus Ferrari, 1867 ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) from Thailand
Abstract Five new species, Anisandrus montanus sp. nov., A. phithakpa sp. nov., A. tanaosi sp. nov., A. triton sp. nov., and A. uniseriatus sp. nov. are described from Thailand. Anisandrus carinensis (Eggers, 1923) is reported from Thailand for the first time and A. apicalis is removed from the Thai fauna. With the inclusion of the species described and recorded here, the diversity of Anisandrus is increased to 40 species, of which 11 occur in Thailand. A synoptic list and a key to the Anisandrus of Thailand are presented. Key words: Key, new records, Oriental region, Thai fauna

| 2:51a | [Herpetology • 2020] Eutropis caraga, E. lapulapu, E. sibalom, etc. • Taxonomic Revision of Philippine Sun Skinks (Squamata: Scincidae: Eutropis), and Descriptions of Eight New Species
Abstract Species descriptions of reptiles historically have relied exclusively on the use of morphological data; however, these external, phenotypic data do not always co-vary with lineage divergence. Consequently, it has become increasingly clear that species diversity has been underestimated in many evolutionary radiations. With the use of an integrative approach, we examined the genetic and morphological diversity present in a nearly endemic Philippine radiation of Eutropis. Results demonstrated that current taxonomy does not reflect evolutionary history and that in many cases, morphological divergence has become decoupled from genetic divergence. As a consequence, species diversity is significantly underestimated. Here, we rectify the major taxonomic problems present in Philippine Eutropis by providing formal descriptions for eight new species. Three of the four new species in the E. multicarinata species complex are sympatric with (and have long been confused with) previously described subspecies (which we also elevate to full species here). The fourth species is endemic to the Caroline Islands, clearly derived from a long-distance dispersal event from the Philippines. The new species in the E. indeprensa species complex are allopatrically or parapatrically distributed across the archipelago. In contrast to the last review of Philippine Eutropis, which suggested the endemic radiation was composed of five species (one of which was composed of two subspecies), we demonstrate that this group includes at least 14 distinct evolutionary lineages, with potential for additional diversity to be discovered pending further study.

| 3:02a | [Crustacea • 2021] Potamalpheops kisi • A New Species of the Genus Potamalpheops (Decapoda: Alpheidae) from the intertidal Mangrove Swamps of South Vietnam
ABSTRACT A new, possibly, infaunal species of the genus Potamalpheops Powell, 1979 (Crustacea: Decapoda: Alpheidae), Potamalpheops kisi sp.n., is described from the intertidal mangrove swamps of the Can Gio Mangrove Biosphere Reserve, South Vietnam. The new species clearly belongs the “P. monodi” species group, but can be easily separated from related species (P. pininsulae Bruce et Illife, 1992, P. tigger Yeo et P.K.L. Ng, 1997 and P. johnsoni Anker, 2003) by the length and shape of rostrum, the length and proportions of carpus and palm of pereiopods I and II, as well as some other minor morphological features. All individuals of the new species were pumped out of burrows in anoxic swamp mud, while no individuals were collected using a hand net during extensive sampling in the same habitats, suggesting that the new species inhabits in a burrow system. No evidence of relationship to any host species is available, since individuals of the new species were collected from different burrows and never with syntopic larger burrowing animals. Observations in situ at nighttime revealed that individuals of Potamalpheops kisi sp.n. freely move inside burrows located above the water level, similar to other mangrove semi-terrestrial shrimp Merguia oligodon, which possibly allows surviving in anoxic conditions of swamp soils; such behavior is described for the genus Potamalpheops for the first time.

| 7:01a | [Botany • 2020] Gonolobus naturalistae (Apocynaceae: Asclepiadoideae: Gonolobeae) • A New Species from México
Abstract A new species of Gonolobus from northwestern Mexico with green and barbate corollas is described here. Gonolobus naturalistae is morphologically similar to G. barbatus, G. pectinatus, and G. sororius but differs in corolla and corona morphology and distribution. Descriptions, illustrations, morphological comparisons, and geographic distribution maps of these species, as well as their conservation status, are provided. This discovery highlights Mexico as a center of diversity for the genus, with around 40 species recorded, and highlights its endemism, with 48.7% of the species occurring in the country.

DOI: 10.11646/phytotaxa.472.3.3  Les presentamos a Gonolobus naturalistae, especie recién descrita. Originalmente se pensó endémica de Sinaloa, pero se encontró una colecta de Chihuahua que originalmente había sido identificada como barbatus. La colecta Tipo quedó para el municipio de Elota, Sinaloa, entre la selva baja del pie de montaña y la planicie costera del Pacífico. El epíteto específico es un tributo a las amistades y nuevas colaboraciones que se logran mediante la plataforma Naturalista Mx, el cual fue el medio por el que los autores del presente se pusieron en contacto. | ||||||||
