| 3:09a | [Botany • 2020] Ceratopteris shingii (Pteridaceae) • A New Species of Ceratopteris with Creeping Rhizomes from Hainan, China
Abstract A new species of fern, Ceratopteris shingii (Pteridaceae), was identified and characterized. It is endemic to Hainan Province, China. Ceratopteris shingii shares similar morphological characters with C. thalictroides but can be easily distinguished by its creeping rhizomes. In addition, molecular evidence indicated that the new species is sister to other Ceratopteris species.

| 3:10a | [Herpetology • 2020] Hemiphyllodactylus bonkowskii & H. ngocsonensis • Two New Species of Hemiphyllodactylus (Squamata: Gekkonidae) from Hoa Binh Province, Vietnam
Abstract We describe two new species of the genus Hemiphyllodactylus on the basis of a new collection of geckos from limestone karst forest of Hoa Binh Province, northwestern Vietnam. Hemiphyllodactylus bonkowskii sp. nov. from Hang Kia—Pa Co Nature Reserve and Hemiphyllodactylus ngocsonensis sp. nov. from Ngoc Son—Ngo Luong Nature Reserve can be distinguished from each other and from their congeners by genetic distinction and morphological differences in circumnasal scales, chin scales, precloacal and femoral pores, cloacal spurs, dorsal scales, ventral scales, digital lamellae formula, and color pattern. In phylogenetic analyses, both new species are nested in a clade that includes H. dushanensis, H. flaviventris, H. hongkongensis, H. huishuiensis, H. kiziriani, H. serpispecus, and H. zugi. In terms of pairwise genetic distance, the two new species are at least 7.5%–8.5% divergent from other described species based on a fragment of the ND2 gene.

Hemiphyllodactylus bonkowskii sp. nov. Distribution. Hemiphyllodactylus bonkowskii sp. nov. is currently known from the type locality in Hang Kia– Pa Co NR, Hoa Binh Province, Vietnam (Fig. 1). Etymology. We name the new species in honour of Prof. Dr. Michael Bonkowski from the Institute of Zoology, University of Cologne, Germany for his support of our biodiversity research in limestone karst forests in Vietnam and Laos. For the common names we suggest Bonkowski’s Slender Gecko (English) and Thạch sùng dẹp bonkowski (Vietnamese). Hemiphyllodactylus ngocsonensis sp. nov. Distribution. Hemiphyllodactylus ngocsonensis sp. nov. is currently known from the type locality in Ngoc Son—Ngo Luong NR, Lac Son District, Hoa Binh Province, northwestern Vietnam (Fig. 1). Etymology. Specific epithet ngocsonensis is a toponym in reference to the type locality of the species. For the common names we suggest Ngocson Slender Gecko (English) and Thạch sùng dẹp ngọc son (Vietnamese).
