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.

Mite Genus

The water mite genus Wettina has a Holarctic distribution and includes only one known species from the Palaearctic, i.e. W. podagrica (Koch, 1837). This species has been considered as a rhitrobiontic and crenophilous species. In the present study we used morphological data and DNA barcoding to describe a new species of the genus, W. lacustris sp. nov. from the glacial Biogradsko Lake in northern Montenegro. The level of COI differentiation between lake population of Wettina lacustris sp. nov. and stream and spring populations of W. podagrica from Western Europe (The Netherlands) was 8.4%. It is likely that Wettina lacustris sp. nov. is more widely distributed in the Palaearctic.

An integrative molecular and morphological study is presented for the family Unidentiidae. Molecular phylogenetic analyses were conducted with the inclusion of all previous and newly obtained molecular data for the family Unidentiidae Millen & Hermosillo 2012. A new species of the genus Unidentia Millen & Hermosillo 2012, U. aliciae sp. nov., is described from Thailand as part of an inventory of sea slugs at Koh Tao. All up-to-date available morphological data for the species of the genus Unidentia is for the first time summarized. Morphological differences among the different species of Unidentia are clarified showing that every species has its own distinguishable morphological traits. According to the new molecular and morphological data, the family Unidentiidae is re-confirmed as a well-supported taxon of the aeolidacean nudibranchs. The taxonomy and phylogeny of the Aeolidacea in the light of the family Unidentiidae is briefly discussed and necessity of a fine-scale and narrowly-defined taxa approach instead of a ‘‘superlumping’’ one is highlighted.

A new species belonging to Lactarius subg. Plinthogalus was discovered during a long-term project on the diversity of Korean Lactarius. This species is proposed here as Lactarius cucurbitoides. The status of L. cucurbitoides as a new species is supported by molecular data and morphological features. Phylogenetic analysis based on internal transcribed spacer (ITS) sequences shows that L. cucurbitoides is closely related to L. subplinthogalus, L. friabilis, and L. oomsisiensis, with pairwise distances of 2.8–4.3%. Morphological characters of L. cucurbitoides that distinguish it from these closely related species are a pale yellow to pale orange colored pileus and non-discoloration of white latex. The new species is described and illustrated in the present paper.

Abstract Chelon caeruleum sp. nov. is described as a new species of Chelon encountered in the Rashid coastal region of the Mediterranean Sea, Egypt. With this finding, the new species is the sixth member of the genus Chelon. Chelon caeruleum sp. nov. is distinguished from its congeners by the following characters: colouration of body is dark bluish grey dorsally and the sides are blue; head length 20.5 to 21.6% SL; head width 13 to 13.5% SL; pre-first dorsal fin length 50% SL; eye diameter 4.6 to 5.2% SL; postorbital length 10.7 to 11.1% SL; unbranched pyloric caeca are 2 short and 4 long; a pair of long (one longer than the other), spine-like neural postzygapophyse on the second vertebra. DNA of Chelon caeruleum sp. nov. and five mullet species (Mugil cephalus, Liza carinata, Liza ramada, Liza aurata, and Chelon labrosus) was extracted then amplified using polymerase chain reaction (PCR) and sequenced. The mtDNA cytochrome oxidase subunit I sequence analysis confirmed that Chelon caeruleum sp. nov. is distinct from other congeners of Chelon and it is a different species of Chelon which is new to science.

A New Species

The taxonomy of Zelentia Korshunova, Martynov & Picton, 2017, a genus of aeolidacean nudibranchs recently separated from Trinchesia Ihering, 1879, is reviewed. Using previous and novel data, including the defining morphological characters of a supplementary gland inserted into the penis, which is also armed with stylet, it is demonstrated that the genus Zelentia is a well-established amphi-boreal taxon. A phylogenetic tree and haplotype network for species of the genus Zelentia are provided. A new species from the Northeastern Pacific, Zelentia willowsi sp. nov. and a second Northeastern Pacific species, Zelentia nepunicea sp. nov., previously thought to be “Cuthona” pustulata (Alder & Hancock, 1854), are described using morphological and molecular data. A new species from the North Atlantic and sub-Arctic White Sea, Zelentia roginskae sp. nov., is also described using morphological and molecular data. The Northeastern Pacific Zelentia nepunicea sp. nov. and“Cuthona” punicea Millen, 1986, which externally share a similar reddish colouration, are shown to belong to two different families since “Cuthona” punicea possesses a supplementary gland inserted into the vas deferens and an unarmed penis, characters of the genus Cuthonella Bergh, 1884, belonging to the Cuthonellidae family. Despite belonging to different families and having significant internal differences, externally Cuthonella punicea and Zelentia nepunicea sp. nov. appear similar, thus the new sympatric species of Zelentia is given the name Z. nepunicea sp. nov. which means non punicea. To facilitate identification and avoid further confusion we provide a comparative table which encompasses diagnostic morphological data for Northeastern Pacific species of the families Cuthonidae, Cuthonellidae and Trinchesiidae which are externally similar to the described new taxa.

Water mites of the genus Neumania have been found worldwide. In the present study we used morphological data and DNA barcoding to describe a new species of the genus Neumania, N. kyrgyzica sp. nov. from Kyrgyzstan. The results supported the genetic separation between the new species and species examined in this study (N. deltoides, N. imitata, N. limosa, N. spinipes and N. vernalis). The lowest K2P divergence (11.7%) was found between the new species and N. limosa (Koch, 1836), a species widely distributed in the Palaearctic region. Morphologically, the new species seems to be most similar to N. alticola (Stoll, 1887), an abundant and widespread species in the extreme northern Neotropics.

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

A new cryptic species of ground-dwelling Hemidactylus (Squamata: Gekkonidae) from southern India. Recently collected specimens of a gecko resembling Hemidactylus reticulatus from northern Karnataka State in southwestern India led me to investigate variation in the species with regards to its morphology and molecular divergence. Results based on existing museum material, combined with molecular data for the mitochondrial cytochrome b gene support the presence of cryptic species within the broadly distributed H. reticulatus complex. Here, I describe a new species of Hemidactylus from northern Karnataka as the frst contribution in resolving the species complex. The integration of molecular and morphological data supports the distinctness of the new species described herein.
