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.

A New Species

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

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.

A New Species

Silene sunhangii, a new species of Caryophyllaceae known from only three populations in Hubei and Hunan provinces of central China, is described. Both morphological and molecular data were used to assess the taxonomic status and relationships of this species. Morphologically, S. sunhangii is most similar to S. platyphylla Franch. from which it differs most readily in having 3-veined elliptical leaves without pubescence, tasseled catacorolla, pale purple to red petals without a linear lobe or narrow tooth and lanceolate, bifid to one third. A phylogenetic analysis based on nuclear ITS region identified the new species as a well-supported, independent lineage. Our new species is nested within a grade that encompasses species representing a polyphyletic Silene sect. Physolychnis (Benth.) Bocquet. Both the genetic and morphological data support the recognition of Silene sunhangii as a distinct species, although there is inconsistency between these two datasets as to the relationships of the new species.

A New Species

A new species from southwest of Bojnord, NE of Iran is described and illustrated here as Dianthus pseudocrinitus (Caryophyllaceae). This species is morphologically similar to D. crinitus subsp. turcomanicus, but can be distinguished from the latter by bract number, width of lower and upper leaves, margin of thickness of outermost bracts, length of calyx, length and width of anther, branches of stem, type of sheath of lower leaf, and tip shape of petal fimbria. The new species is also similar to D. orientalis subsp. stenocalyx in terms of floral characters, but they differ by several non- overlapping morphological characters. Results obtained from the morphological data are consistent with those obtained from the molecular phylogenetic trees based on sequences of the two copies of DFR1 gene, confirming phylogenetic affinity of the new species to D. crinitus subsp. turcomanicus.

Lines Of Evidence

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

A New Species

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.

A new species of the genus Cyrtodactylus is described from Dien Bien Province, northwestern Vietnam based on morphological and molecular data. Cyrtodactylus ngati sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 69.3 mm; dorsal pattern consisting of six dark irregular transverse bands between limb insertions; inter-supranasals one; dorsal tubercles present on occiput, body, hind limbs and on first half of tail; 17–22 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, with interspersed tubercles; 32–38 ventral scales between ventrolateral folds; 13 precloacal pores separated by a diastema of 5/5 poreless scales from a series of 7/7 femoral pores in enlarged femoral scales; precloacal and femoral pores absent in females; 1–3 postcloacal tubercles on each side; transversely enlarged median subcaudal scales absent. In the molecular analyses, the new species is shown to be the sister taxon to C. interdigitalis from Thailand. This is the 47th species of the genus Cyrtodactylus and the first member of the C. brevipalmatus species group recorded from Vietnam.
