| 3:54a | [Crustacea • 2024] Parapleurocrypta duofratres • A New Species of Parapleurocrypta Chopra, 1923 (Isopoda: Epicaridea: Bopyridae) Parasitizing Shrimps of the Genus Synalpheus (Decapoda: Caridea: Alpheidae) from the Fernando de Noronha Archipelago, Brazil
A new species of Parapleurocrypta Chopra, 1923, a parasitic isopod genus of the family Bopyridae found parasitizing two species of the snapping-shrimp genus Synalpheus Spence Bate, 1888, is described from Brazil. This is the first record of Parapleurocrypta in the Atlantic Ocean, and the first species of bopyrid parasite recorded from the Fernando de Noronha archipelago in northeastern Brazil. Females of Parapleurocrypta duofratres sp. nov. can be distinguished from the other two species of the genus, P. alphei Chopra, 1923 and P. digitata Bourdon, 1976, by the structure of the barbula, the reduced pleopods, the number of dorsolateral bosses, the absence of the frontal lamina (present in P. digitata), and pleomeres with lateral plates (vs. lateral plates absent in P. digitata). Males can be distinguished from those of P. alphei by the number of antennal articles. Variation in the specimens is discussed and ecological and reproductive data are provided. To accommodate the new features of P. duofratres sp. nov., the diagnosis of the genus is expanded. A review of the branchial bopyrids of Synalpheus is included, as well as a discussion of parasitism by members of Parapleurocrypta.

| 3:57a | [Botany • 2024] Triaspis bicuarensis (Malpighiaceae) • A New Angolan Species from the Triaspis hypericoides complex based on Macromorphology and Palynology
Abstract Triaspis hypericoides currently comprises three accepted subspecies endemic to woodland savannas of southern continental Africa. After an unusual population belonging to this complex was collected in southwestern Angola, we re-evaluated the classification of this group. This study was based on the analysis of type specimens, protologues, field photographs and herbarium sheets of all subspecies within T. hypericoides. We reinstate T. canescens, T. hypericoides and T. nelsonii based on differences in leaf, flower and fruit traits. Additionally, the Angolan population is proposed here as a new species of Triapis endemic to the dry miombo woodlands of Bicuar National Park, Huíla Province, southwestern Angola. Triaspis bicuarensis sp. nov. is easily distinguished from T. nelsonii by its alternate (versus opposite) leaves, ovate to widely ovate (versus widely ovate to very widely ovate) leaf laminas, rounded (versus sagittate) leaf base, flat (versus undulate) margins, sparsely white-tomentose (versus glabrous to glabrescent) abaxial leaf surface, petiole 4–8 mm long (versus 2–3 mm long), compound inflorescences in thyrses (versus corymbs) and bracteoles inserted below apex of peduncles (versus in the middle of peduncles). An identification key to all species belonging to this species complex is presented alongside a complete morphological description for the new species, photographic plates and comments on the distribution, ecology, palynology and taxonomy. These results underline the need for continued revisions of the taxonomy of the neglected African genera of Malpighiaceae. Keywords: Angola, Malpighiales, Malpighioid clade, savanna, tropical Africa   Triaspis bicuarensis R.F.Almeida and Goyder, sp. nov. Diagnosis: A species differing from T. nelsonii due to its alternate (versus opposite) leaves, with ovate to widely ovate (versus widely ovate to very widely ovate) lamina, rounded at base (versus sagittate), with flat margin (versus undulate), abaxially sparsely white-tomentose (versus glabrous to glabrescent), petiole 4–8 mm long (versus 2–3 mm long), flowers in thyrses (versus corymbs) and bracteoles inserted below apex of peduncles (versus inserted at the middle of peduncles). Etymology: The epithet refers to the restricted distribution of the new species, known only from Bicuar National Park in Huíla Province, southwestern Angola.

| 8:51a | [Arachnida • 2024] Hottentotta hatamtiorum • Integrative Systematics of the widespread Middle Eastern buthid Scorpion, Hottentotta saulcyi (Simon, 1880) (Scorpiones: Buthidae), reveals A New Species in Iran
Abstract Morphological and genetic variation among populations of the widespread buthid scorpion, Hottentotta saulcyi (Simon, 1880), occurring in western and southwestern Iran was explored using morphometric variables, one nuclear marker (28S rDNA) and three mitochondrial markers (12S rDNA, 16S rDNA, and Cytochrome c Oxidase Subunit I). Genetic and morphometric statistical analyses revealed extensive cryptic diversity. Phylogenetic analysis with Bayesian Inference and Maximum Likelihood uncovered two divergent clades, one of which is described as a new species, Hottentotta hatamtiorum sp. nov., from Ilam and Khuzestan Provinces, southwestern Iran. The description of the new species raises the total count of Hottentotta Birula, 1908 species to 61, twelve of which are endemic or subendemic to the Iranian Plateau. Key words: Cryptic diversity, morphology, morphometrics, taxonomy
Hottentotta hatamtiorum sp. nov. Diagnosis: Hottentotta hatamtiorum sp. nov. may be distinguished from H. saulcyi by the wider metasomal segment I (MtIL/WHsau 1.01 ± 0.06; MtIL/WHhat 1.17 ± 0.11) and telson (TWHsau 3.99 ± 0.62; TWHhat 4.25 ± 0.70); from H. akbarii by the infuscate anterior part of the carapace, metasomal segment V, and telson; from H. lorestanus by the uniformly yellowish-brown base color; and from H. khoozestanus by the shorter fingers of the pedipalp chela (ChL/ML 2.35; MFL/ML 1.36) and the infuscate ventral and ventrolateral surfaces of metasomal segment V and telson. Etymology: The specific epithet refers to Hatamti, an ancient civilization centered in the far west and southwest of modern-day Iran (3200–539 BC), in the lowlands of present-day Khuzestan and Ilam provinces and a small part of southern Iraq.

| 9:08a | [PaleoEntomology • 2018] Cretohister sinensis • Cretohisteridae, a new beetle family (Coleoptera) from the Early Cretaceous of China, and its implications for the early evolution of the basal group of Histeroidea
Abstract A new beetle family Cretohisteridae fam. n. is described from the Lower Cretaceous Yixian Formation (∼125 Ma) at Huangbanjigou of Beipiao City, Liaoning Province, Northeastern China based on a well preserved fossil beetle, Cretohister sinensis gen., sp. n. This discovery has established the oldest fossil record for the superfamily Histeroidea, backdating the minimum age of the group by 25 Ma from the earliest Cenomanian (∼99 Ma) to the Barremian of the Cretaceous Period. Based on cladistic analyses of a comprehensive morphological dataset, Cretohisteridae is unambiguously recovered as the sister group of Histeridae, exhibiting several character states that bridge the span between Sphaeritidae, Synteliidae and Histeridae. The discovery of the new fossil family sheds new light on the early evolution and diversity of the Histeroidea in the Early Cretaceous, and provides new clues to solving the long-ambiguous phylogenetic relationships among the modern families of Histeroidea.

| 9:50a | [Herpetology • 2024] Cyrtodactylus regicavernicolus • A New Species in the Cyrtodactylus intermedius Group (Squamata: Gekkonidae) from an isolated Limestone Karst formation in southwestern Cambodia
Abstract The gekkonid lizard Cyrtodactylus intermedius was formerly considered to be a single widespread species in hilly areas across eastern Thailand through southern Vietnam but has recently been partitioned into a complex of 12 nominal species across its range. A population belonging to the C. intermedius group was recently found in an isolated limestone karst block in Kampot Province in southwestern Cambodia, part of which lies within the recently designated Phnom Preah Kuhear Loung Natural Heritage Site. Comparisons of morphometric, meristic, qualitative morphological and color pattern data, as well as a molecular analysis using the mitochondrial ND2 gene, revealed that this population differs from all other named members of the C. intermedius group, and so is described here as a new species. The karst-dwelling C. regicavernicolus sp. nov. was recovered as the sister species to C. laangensis, the most geographically proximate member of the complex and one that is also restricted to a small limestone karst habitat.
