[Botany • 2022] Kaempferia sipraiana (Zingiberaceae) • A New Species from Thailand and a new record of Kaempferia pseudoparviflora for Myanmar  | Kaempferia sipraiana Boonma & Saensouk,
in Boonma, S. Saensouk et P. Saensouk, 2022. |
Abstract Kaempferia sipraiana Boonma & Saensouk, a new species of Kaempferia subgenus Protanthium (Zingiberaceae) from northern Thailand and K. pseudoparviflora Saensouk P. & Saensouk, a new record species of Kaempferia subgenus Kaempferia for Myanmar are described, illustrated, and photographed. The dominant characters of Kaempferia sipraiana were leaves narrowly elliptic, green with short white stripes arranged parallel along the leaf edges, between the midrib and both sides of the edges, apex acuminate with slightly mucronate, base attenuate-oblique; peduncle glabrous; bracts apex mucronate, glabrous, red with dark red veins; bracteoles glabrous; floral tube shorter than calyx; calyx glabrous; staminodes oblanceolate, apex 3-lobes like curly brackets; labellum white at the base with pinkish purple in the middle gradually fade to pale pink and to reach to white tip and edge respectively, apex 3-lobes like curly brackets, each lobe 3.0–3.3 cm long; apex 4 lobes, outer lobes acute, inner lobes obtuse rarely combined to truncate; stigma with pink lips. The dominant characters of K. pseudoparviflora were one leaf and dark green with light grey markings, the inflorescence looks like inflorescence of K. parviflora. The information on vernacular name, distribution, phenology, ecology, conservation status, specimens examined, and an identification key to both species of Kaempferia in Thailand is revised and presented.

[Herpetology • 2024] Atelopus colomai • A New Species of Harlequin Toad (Anura: Bufonidae: Atelopus) from Amazonian Ecuador
 | Atelopus colomai

Abstract For nearly four decades, harlequin toads, genus Atelopus, have sufered unparalleled population declines. While this also results in limited understanding of alphataxonomic relationships, these toads face an urgent need for advances in systematics to inform conservation eforts. However, high intraspecifc variation and cryptic diversity have hindered a comprehensive understanding of Atelopus diversity. Tis is particularly exemplifed among Amazonian populations related to A. spumarius, where decades of taxonomic work have not been able yet to unravel relationships between the many forms, while the names coined so far have led to taxonomic confusion leaving numerous lineages unnamed. A recent comprehensive phylogenetic study has revealed new insights into the systematics of harlequin toads with an emphasis on Amazonian forms, identifying several unnamed lineages. We here describe one of these evolutionary lineages as a new species, restricted to the Ecuadorian Amazon basin, in an integrative taxonomic approach using molecular, morphological, bioacoustic and larval information. With this, we contribute to a better understanding of Atelopus diversity as the baseline of conservation action.

Atelopus colomai sp. n.
Diagnosis: Atelopus colomai sp. n. (Figs 1–2, S1) can be readily distinguished from all other Atelopus species (as far known) by molecular genetics (monophyly in a concatenated (12S, 16S, CytB) mitochondrial phylogeny, support by molecular species delimitation and lack of haplotype sharing in POMC, Lötters et al. in press). It can be morphologically distinguished from all congeners by the combination of small size, dorsal and lateral skin covered with dense well-defned minute spiculae, ventral skin smooth to slightly areolate, presence of a columella and dorsal ...
Etymology: We dedicate this species to our friend and colleague Luis A. Coloma, who has continuously contributed to the study and protection of harlequin toads for decades. Te specifc name colomai is an eponym (i.e. a noun in genitive case). As English common name, we propose ‘Coloma’s harlequin toad’
