A New Species

A new species of endemic, insular Cnemaspis is described from Hon Khoai Island, Ca Mau Province, Ngoc Hien District, 18 km off the southern tip of the Ca Mu Peninsula in southern Vietnam. Cnemaspis psychedelica sp. nov. is the most uniquely colored of all southeast Asian Cnemaspis in that both sexes and all age classes have bright orange forelimbs, forelegs, hands and feet; a bright orange tail; a dense, yellow reticulum on the neck overlying thick, black, longitudinal lines; and a blue-gray to light purple trunk bearing yellow transverse bars on bright-orange flanks. It also differs from all other species of Cnemaspis in aspects of size and squamation. Cnemaspis psychedelica is the third insular endemic species of Cnemaspis from Vietnam and brings the total number of species in Vietnam to six. Its occurrence on one of the 92 islands in Rach Gia Bay underscores the necessity for continued surveys of these poorly known islands that are beginning to show a surprising degree of endemism and diversity.

A New Species

We describe a new species of the gekkonid genus Gekko from southern Vietnam on the basis of three adult specimens from Cuc Dong Cape, Ninh Hoa District, Khanh Hoa Province. Gekko truongi sp. n. is distinguished from congeners by the combination of the following characters: medium-sized species with a maximum 95.9 mm SVL; supralabials 13–15; postmentals enlarged; interorbitals 45–58; dorsal tubercles absent; well developed lateral folds; scales between mental and cloaca 160–172; ventrals 35 or 36; subdigital lamellae below first toe 11–13, below fourth toe 15–17; faint basal webbing between fingers and toes; precloacal pores in males 10 or 11; postcloacal tubercles in males 1/1; number of transverse dorsal scale rows in the middle of the third caudal whorl 11; a prominent light postocular stripe is lacking; dorsum grey with dark pattern and light blotches and lines.

We describe a new species of leaf-toed gecko of the genus Phyllodactylus from María Cleofas Island, the smallest island of Tres Marías Archipelago, Nayarit, México. Genomic, phylogenomic, and morphological evidence support that the new species presents a unique combination of diagnostic characters. Morphologically, the new species has a high number of tubercles, head to tail (mean 47), longitudinal ventral scales (mean 61), and third labial–snout scales (mean 26). Gene flow tests revealed the genetic isolation of insular populations from mainland counterparts. In addition, we confirmed the non-monophyly of P. homolepidurus and P. nolascoensis, and we show that the taxon P. t. saxatilis is a complex; therefore, we propose taxonomic changes within the saxatilis clade. The discovery of this new insular endemic species highlights the urgency of continued exploration of the biological diversity of island faunas of Mexico.

Acanthodactylus boskianus is a widespread species in Northern Africa and Western Asia. In this study, we used morphological and genetic approaches to study populations of A. boskianus from the Zagros Mountains in western Iran, the easternmost limit of the species’ distribution. Our morphological and genetic data indicate that populations of A. boskianus in Iran are distinct from other populations of A. boskianus. Therefore, we describe the Iranian populations as Acanthodactylus zagrosicus sp. nov. The new species is the third endemic species of Acanthodactylus in Iran and the ninth Acanthodactylus species distributed in Iran overall. According to our surveys, this species is distributed widely in the Zagros Mountains including Kermanshah, Lorestan, Ilam, and Khuzestan Provinces.

We describe a new species of pitviper Cryptelytrops honsonensis sp. nov. from Hon Son Island in Rach Gia Bay, Kien Giang Province of southern Vietnam based on it having unique aspects of scalation, body proportions, and color pattern. It is similar to C. venustus in morphology and color pattern and the putative close relationship between these species would corroborate a biogeographical link across southern Indochina seen in a number of other taxa. The presence of this newly discovered insular endemic in Rach Gia Bay and other insular endemics of Rach Gia Bay addressed herein, underscores the understudied nature of these islands and the need for their continued conservation.

Aralia hiepiana J.Wen & Lowry (Araliaceae), a new species from southern Vietnam, is described and illustrated by J. Wen & Lowry in 2002. Up to now, there are not any chemical data from this endemic species. By various chromatography methods, four flavonoids compounds namely kaempferol 3,7-O-α-L-dirhamnopyranoside (1), kaempferol 3-O-β-D-glucopyranosyl-7-O-a-L-rhamnopyranoside (2), kaempferol (3), quercetin (4), apigenin 7-O-β-glucopyranoside (5) were isolated from the methanol extract of leaves of Aralia hiepiana collected in Da Lat, Lam Dong province. Their structures were elucidated using 1-D and 2-D NMR techniques and by comparison with the literature data. This is the first time to isolate these compounds from Aralia hiepiana.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao & Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu & Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu & Li, 2006 (Fam. Linyphiidae) are also illustrated.

We sampled two forms of Leptobrachium in syntopy at the type locality of L. pullum at upper elevations on the Langbian Plateau, southern Vietnam. The two forms differed in morphology (primarily in coloration), mitochondrial DNA, and male advertisement calls. One form closely agrees with the type series of L. pullum (but not to its original description due to error), and the other is described as new. Leptobrachium leucops sp. nov. is distinguished from its congeners by having small body size (males with SVL 38.8–45.2), the upper one-third to one-half of iris white, a blue scleral arc, a dark venter, and sexually active males without spines on the upper lip. Leptobrachium pullum and L. mouhoti, a recently described species from low-elevation slopes of the Langbian Plateau in eastern Cambodia, are morphologically divergent but genetically similar, warranting further investigation into geographic variation in the red-eyed Leptobrachium of southern Indochina.

A new species of the Cyrtodactylus irregularis group is described from Ninh Thuan Province, southern Vietnam based on molecular divergence and morphological differences. Cyrtodactylus orlovi sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by having the unique combination of the following characters: size medium (SVL 61.0–77.7 mm); dorsal tubercles in 16–20 irregular rows; 36–39 ventral scale rows; precloacal pores absent in females, 5 or 6 in males, in a continuous row; femoral pores absent; 3–8 enlarged femoral scales; postcloacal spurs 1 or 2; lamellae under toe IV 16–19; a continuous neckband; a highly irregular transverse banded dorsal pattern; the absence of transversely enlarged median subcaudal scales. In phylogenetic analyses, the new species was revealed to be the sister taxon to a clade consisting of Cyrtodactylus cattienensis and the most recently described species from Vietnam, C. chungi, with 12.1–12.4% and 11.7 % pairwise genetic divergence from the two species, respectively, based on a fragment of the mitochondrial COI gene.
