A New Species

A new species of horned toad, Megophrys ombrophila sp. nov., is described based on specimens found from Guadun village from Mount Wuyi in northwestern Fujian Province, China. The species is distinguished from other described Megophrys by morphology, bioacoustics, and molecular data of the 12S and 16S mitochondrial loci. The species is characterized by its rotund stature, head length approximately equal to head width, canthus rostralis well developed, tympanum large and distinct, vomerine teeth absent, margin of tongue smooth, not notched from behind, heels of the feet not meeting when femurs are held at 90° to the axis of the body and tibias are depressed against the femur, toes weakly webbed at base, dorsal skin mostly smooth with scattered granules and ridges, usually the presence of two discontinuous dorsolateral ridges, supratympanic fold distinct and well-developed, and with females ranging from 32.8–35 mm snout-to-vent length, and males ranging from 27.4–34.5 mm SVL. In its type locality, the species is sympatric with M. boettgeri and M. kuatunensis; and phylogenetically, the most closely related described species is M. obesa from southwest Guangdong province. As more cryptic species are described within the subfamily Megophryinae, the more apparent becomes the need for fine-scale molecular and phenotypic assessment to capture the many forms of this hyper-diverse group.

A New Species

We describe a new horned toad species of the genus Megophrys from Yingjiang County of Yunnan Province, China. The new species, Megophrys feii sp. nov., can be distinguished from its congeners by a combination of the following characters: (1) body slender and small (SVL 24.3–25.1 mm in four males, 28.2–28.9 mm in two females); (2) head length about equal to head width (HDL/HDW 0.97–0.99); (3) tympanum circular and distinct; (4) maxillary teeth present; (5) vomerine ridges and vomerine teeth absent; (6) tongue round, slightly notched posteriorly; (7) tibia long (TIB/SVL 0.48–0.52 in four males, 0.54–0.55 in two females), shanks overlapping when thighs are held at right angles to the body; (8) dorsal skin distinctly granular and densely covered with small tubercles; (9) lower flanks and lateral sides of belly scattered with small but prominent, white, tubercles; (10) webbing between toes rudimentary; (11) lateral fringes on toes moderate to wide; (12) breeding males without nuptial pads and spines on fingers; (13) protruding projection posterior to cloaca present in both sexes; (14) groin and ventral thigh coloration in life not contrasting with surrounding regions; (15) the presence of an indistinct and small horn-like tubercle at the edge of the eyelid; and (16) an advertisement call with a dominant frequency of 4.74–4.91 kHz (at 18 ˚C). To date, the new species has only been found at its type locality in stream areas in montane evergreen broadleaf forests between 700–1200 m elevation.

A New Species

A new species, Camellia psilocarpa (Theaceae), from Guangdong Province, China, is described and illustrated. It is morphologically most similar to C. magnocarpa, from which it differs by having ovate-oblong leaves with apex caudate or long acuminate, bracteoles and sepals 10-12, grayish white velutinous outside, and especially smaller fruit. The morphological evidence shows that the new species is a member of Camellia sect. Camellia. Additionally, a molecular and phylogenetic analysis using two chloroplast DNA markers also gave support to its taxonomic position.

The type of Rossbeeverabispora and additional collections from the type location and adjacent areas were studied. Molecular data for R.bispora derived from the new collections are provided. In addition, R.griseobrunnea, a new species of Rossbeevera, is described from Xiangtoushan National Nature Reserve, Guangdong Province of China. The new species is characterized by its globose to subglobose sequestrate basidiomata with grayish white to grayish brown pileus, pale bluish discoloration in some parts of the hymenophore when injured becoming rusty brown to dark brown after being exposed to the air, fusoid (star-shaped in cross section) basidiospores 17–20 × 9–12 μm, and subcutis elements in the pileus. Based on multi-locus (ITS+nrLSU+tef1-α+rpb2) molecular phylogenetic analyses, both species appear as sister to R.paracyanea. We present color photos, macro- and micro-description, SEM basidiospores, molecular affinities of the species and compare them with morphologically similar taxa within the genus. A key to the species known from northern and southern hemispheres is provided.

This paper reports on a new species of the Baikal endemic sponge (fam. Lubomirskiidae) Swartschewskia khanaevisp. nov. The description of this species is based on morphological and molecular data (ITS and mitochondrial IGRs). Morphologically, S. khanaevisp. nov. differs from S. papyracea by loose tracts arranged in an irregular network as well as the presence on strongyles of compound spines looking like tubercles densely ornamented with simple spines. Moreover, specimens of S. khanaevisp. nov. show a peculiar structure of the aquiferous system at the body surface that may be an adaptive trait for environmental conditions. Phylogenetic analysis has revealed that S. khanaevisp. nov. forms a well-supported (0.99) monophyletic clade with S. papyracea and is allocated as its sister taxa.

A new species of Megophrys is described from Cao Bang Province, northeastern Vietnam based on morphological and molecular data. Morphologically, the new species is distinguishable from its congeners by a combination of the following characters: Size small (SVL 34.9–38.9 mm in males); tympanum visible; vomerine teeth absent; tongue not notched posteriorly; male with a single vocal sac; toes with rudimentary webbing; subarticular tubercles and lateral fringes absent on all digits; nuptial pads present on fingers I and II in males, with spicules; dorsal skin with scattered granules and tubercles; flank with tubercles; dorsum with a X-shaped dorsal ridge; dorsolateral folds prominent; a small horn-like tubercle present at the outer edge of the eyelid; dorsal surface yellowish brown with a dark brown triangle between the eyes, and a dark brown marking along the X-shaped ridge on the back. In the phylogenetic analyses, the new species is unambiguously nested within the subgenus Panophrys with interspecific uncorrected genetic p-distances (16S rRNA gene) varying from 4.26% (compared with M. rubrimera) to 10.80% (compared with M. acuta).

A new species, Xenophrys jinggangensis sp. nov., is described based on a series of specimens collected from Mount Jing-gang, Jiangxi Province, Eastern China. The new species can be easily distinguished from other known congeners by mor-phology, morphometrics and molecular data of the mitochondrial 16SrRNA gene. The new species is characterized by itssmall size with adult females measuring 38.4–41.6 mm in snout-vent length and males measuring 35.1–36.7 mm; headlength approximately equal to head width; tympanum large and distinct, about 0.8 times of eye diameter; vomerine teethon two weak ridges; tongue not notched behind; relative finger length II < I < IV < III; slight lateral fringes present ondigits; toes bases with thick, fleshy web; dorsum with tubercles and swollen dorsolateral folds; large pustules scattered on flanks; and unique color patterns. The new species represents the thirty-first known Xenophrys in China.

A New Species

A new species of the Asian leaf litter toad genus Leptobrachella is described from Guizhou Province, China. Molecular phylogenetic analyses support the new species as an independent lineage deeply nested in the Leptobrachella clade. The new species is distinguished from its congeners by a combination of the following morphological characters: body size medium (SVL 29.7–31.2 mm in five adult males); dorsal skin shagreened, some of the granules forming longitudinal short skin ridges; tympanum distinctly discernible, slightly concave; supra-axillary, femoral, pectoral and ventrolateral glands distinctly visible; absence of webbing and lateral fringes on fingers; toes with narrow lateral fringes but without webbing; heels overlapping when thighs are positioned at right angles to the body; tibia-tarsal articulation reaching the middle of eye when leg stretched forward. The discovery highlighted the underestimated species diversity in the Leptobrachella toads in southwestern China.
