| 12:03p | [Entomology • 2021] Revision of the Palearctic Cicindela campestris Species Complex (Coleoptera, Cicindelidae) — Part 1: On the Taxonomy, Identification and Ecology of Cicindela herbacea and C. javetii
Abstract We revise the taxonomically problematic Palearctic Cicindela campestris species complex, a group of green tiger beetle species, using an integrative approach combining morphology, morphometry and biogeography. In this first part, an identification key to all subgroups of these green tiger beetles (Cicindela herbacea-subgroup, Cicindela javetii-subgroup, Cicindela desertorum-subgroup, Cicindela campestris-subgroup, Cicindela turkestanica-subgroup and Cicindela asiatica-subgroup) based on large series taken from private and museum collections as well as on literature sources is provided and diagnostic characters are illustrated by detailed photographs. The Cicindela herbacea- and Cicindela javetii-subgroups are revised and illustrated and identification keys as well as distribution maps for both are given. Four new synonyms are established: Cicindela herbacea herbacea Klug, 1832 = Cicindela herbacea aleppensis Deuve, 2012, syn. n.; Cicindela herbacea turkestanicoides W. Horn, 1938 = Cicindela herbacea perreaui Deuve, 1987, syn. n. = Cicindela herbacea colasi Deuve, 2011, syn. n.; Cicindela javetii javetii Chaudoir, 1861 = Cicindela thughurica Franzen, 2007, syn. n.

| 12:16p | [Entomology • 2022] Rugabinthus gen. nov. • A New Genus of Lebinthina (Orthoptera: Gryllidae: Eneopterinae) from New Guinea
Abstract Brachypterous crickets from the monophyletic group of Lebinthina were traditionally grouped under the genus Lebinthus. However, the morphology and calling song are highly diversified, prompting the erection of numerous genera to reclassify the species. Based on the strong characteristic fold carrying the diagonal vein of the male forewing, a new genus of cricket from the subtribe Lebinthina is described: Rugabinthus gen. nov. This brachypterous genus is endemic to the island of New Guinea and nearby islands. We redescribe the type species Rugabinthus leopoldi (Chopard, 1931) comb. nov. and describe 12 new species, R. manokwari sp. nov., R. kencana sp. nov., R. maoke sp. nov., R. nabire sp. nov., R. albatros sp. nov., R. karimui sp. nov., R. yayukae sp. nov., R. biakis sp. nov., R. mamberamo sp. nov., R. tariku sp. nov., R. faowi sp. nov., and R. baduri sp. nov. We also transferred R. newguineae (Bhowmik, 1981) comb. nov. and provide a key to all known species of Rugabinthus gen. nov. Keywords: Grylloidea, Lebinthini, new species, Papua, Southeast Asia, taxonomy  Taxonomy Family Gryllidae Laicharting, 1781 Subfamily Eneopterinae Saussure, 1874 Tribe Lebinthini Robillard, 2004 Subtribe Lebinthina Robillard & Tan, 2021 Genus Rugabinthus Robillard & Tan, gen. nov. Type species.— Lebinthus leopoldi Chopard, 1931 Diagnosis.— Among the Lebinthina genera, Rugabinthus species are average to large sized and stocky with a dark brown coloration. General shape close to that of Macrobinthus, also from New Guinea, from which it differs by male FWs with a narrow triangular harp (shield shaped in Macrobinthus) occupying half of FW width, with a characteristic and strong diagonal fold carrying the diagonal vein and cell c1, and separating FWs in two distinct areas; file vein area also characterized by a strong bean-shaped sclerotization; harp with a strong transverse oblique vein, bi- or poly-furcated anteriorly; venation posterior to diagonal fold usually faint and reticulated, longitudinal veins only strong at apex. Eyes prominent and large as in Macrobinthus compared to Agnotecous and Centuriarus; face as high as wide (higher than wide in Macrobinthus), close to that of Lebinthus. Microptery in both sexes, FWs not reaching mid-length of abdomen. Mirror not differentiated (slightly differentiated in Macrobinthus). CuA almost straight (clearly curved inwards in Macrobinthus). Male genitalia with pseudepiphallus usually elongate, its posterior apex highly variable in size and shape, rami short; pseudepiphallic parameres made of two main lobes variable in shape and orientation; endophallic sclerite very long, trifid posteriorly. Female: FWs shorter than in males, very slightly overlapping, generally rounded posteriorly. Ovipositor rather long, its apex slightly denticulate on dorsal edge. Female copulatory papilla usually rounded, with a C-shaped basal sclerite; apex rounded, generally folded ventrally.
Etymology.— Genus named after the Latin word “Ruga” for wrinkle or fold, referring to the characteristic fold on the male FW carrying the diagonal vein. Distribution.— Island of New Guinea: Indonesia (West Papua) and Papua New Guinea (Fig. 3).  Ming Kai Tan and Tony Robillard. 2022.

| 1:22p | [Herpetology • 2022] Hemidactylus hegdei • A New Species of Large-Bodied Gecko of The Genus Hemidactylus Goldfuss, 1820 (Squamata: Gekkonidae) from Southern Western Ghats of Tamil Nadu, India
Abstract A new species of large-bodied Hemidactylus is described from the southern Western Ghats of Tamil Nadu, India. The species is a member of the prashadi group of Indian Hemidactylus and can be distinguished from all other members of the group by a combination of several morphological diagnostic characters. Based on preliminary phylogeny, using a partial fragment of mitochondrial cytochrome b (cyt b) gene, the new species appeared to be closely allied to H. acanthopholis Mirza & Sanap, 2014; however, the species can be distinguished from H. acanthopholis by its much lower femoral pore count, besides 8% uncorrected sequence divergence for the cyt b gene.

| 1:46p | [PaleoIchthyology • 2022] Qingshuiaspis junqingi & Anjiaspis ericius • The Oldest Eugaleaspiform Ffishes from the Silurian Red Beds in Jiangxi, South China and Their Stratigraphic Significance
Abstract Two new species of Eugaleaspiformes, Qingshuiaspis junqingi gen. et sp. nov. and Anjiaspis ericius sp. nov., were described from the lower Telychian Qingshui Formation in Wuning, Jiangxi Province. Our phylogenetic analysis reveals that Qingshuiaspis clusters with Shuyu, Meishanaspis, and Jiangxialepis to form the clade Shuyuidae, which is the sister to all other Eugaleaspiformes. These represent the oldest and most primitive fossil occurrences of Eugaleaspiformes in the marine Lower Red Beds of Silurian in South China. The new fossil evidence indicates that the vertebrate assemblages consisting of Shuyu, Meishanaspis, and Anjiaspis from the Silurian marine red beds in northwestern Zhejiang are more comparable to that of the Qingshui Formation (Lower Red Beds) than that of the Xikeng Formation (Upper Red Beds) in Jiangxi Province. The fish-bearing marine red beds in northwestern Zhejiang probably belong to the Tangchiawu Formation rather than the Maoshan Formation, and its age should be modified as early Telychian, about 438 million years ago. The oldest eugaleaspiforms and polybranchiaspiforms from the marine Lower Red Beds of Silurian in South China demonstrate that the two major groups of galeaspids split no later than the early Telychian.

| 2:42p | [Botany • 2022] Begonia francisabuidii (Begoniaceae, sect. Baryandra) • A New Species Endemic to Albay, Luzon Island, Philippines
Abstract Begonia francisabuidii from Albay, Bicol region, Luzon Island is here described as a new species endemic to the Philippines. Belonging to section Baryanda, it resembles B. madulidii but is distinguished by shorter and puberulent rhizomes, densely hirsute stipules, reddish and pubescent petiole, smaller leaves, puberulous panicle, smaller bracts and 4-tepaled pistillate flower. According to the IUCN red list categories and criterion, B. francisabuidii is proposed to be placed in the Critically Endangered (CR) category. Keyword: Begonia madulidii, biodiversity, conservation, critically endangered, Southeast Asia, taxonomy
 
 Begonia francisabuidii C.J.P.Dela Cruz, S.R.Concepcion & Y.P.Ang, sp nov. § Baryandra Diagnosis: Begonia francisabuidii is similar to B. madulidii in overall habit: oblique to widely ovate lamina with an acuminate apex, pale green and glabrous adaxially, stipules ovate-triangular and strongly keeled, bracts widely ovate. However, the new species differs in having subpubescent rhizomes (vs. glabrous), petiole reddish and pubescent (vs. pale green with very sparsely erect velutinous hairs), smaller lamina (13–15.1 × 8–10 cm vs. 11.5–21.5 × 9.5–18 cm), panicle puberulous (vs. glabrous), smaller bracts (3–4 mm long vs. 10–12 mm long) and pistillate flower 4-tepaled (vs. 5-tepaled). A more detailed comparison is provided in Table 1. Etymology: This Begonia is named after the late young Bicolano conservation biologist, Mr. Francis Gregor P. Abuid (1996–2021), in acknowledgement of his efforts in inspiring young Bicolanos to protect, conserve, and study the biodiversity of the Bicol region. Distribution and Ecology: Begonia francisabuidii is known only from a small area in Barangay Oma-Oma, Ligao City, Albay. The main population occurs on semiexposed limestone rock near a waterfall, seen growing along with Selaginella sp.   Cyrus Job P. Dela Cruz, Steven R. Concepcion and Yu Pin Ang. 2022.
