A New Species

A new species of Plutomurus Yosii, 1956, P. jangamensis sp. nov., was found in a limestone cave of South Korea. The new species is very similar to P. gul (Yosii, 1966) in the general pattern of cephalic and body chaetotaxy, absence of eye, presence of pointed tenent hair, number of lateral macrochaetae in basal segment of dens, and number of mucronal intermediate tooth; however, the two species can be distinguished by the small spines arranged in-a-row along with dental spines and lighter body color. This species, however, shows variability and was not easily classified morphologically as P. jangamensis sp. nov. and P. gul., in terms of body color, formula of dental spine, or even the number of prelabral chaetae. Partial DNA sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene were used as DNA barcodes to distinguish the species. This result suggests that the COI gene is useful for discrimination of P. jangamensis sp. nov. with high support (bootstrap=100). An identification key to the world species of Plutomurus is also provided.

A New Species

A new species, Anurophorus hallaensis sp. nov. was collected from the withered leaves of Korean fir (Abies koreana Wilson), which is distributed at higher than 1,300 m in altitude on Mt. Hallasan (Jeju Island, South Korea). The morphology and two partial gene regions of this species are described herein. Anurophorus hallaensis sp. nov. showed the same formulas of macrochaetae and sensilla on thoracic segment II to abdominal segment IV as those exhibited by A. laricis Nicolet and A. palearcticus Potapov; however, this new species can be distinguished from them by the number of knobbed hairs on ventral side of legs. Partial DNA sequences of the mitochondrial Cytochrome c Oxidase subunit I (COI) gene and ribosomal DNA (28S rDNA) were used as DNA barcodes to distinguish between A. hallaensis sp. nov. and closely related congeners. The results of the present study indicate that the COI and rDNA are useful for species discrimination within the genus Anurophorus. An identification key to the Korean species of Anurophorus is provided.

A New Species

Background The Amazon basin is recognized as one of the most complex and species-rich freshwater environments globally. The diversity of zooplankton here remains unknown, with many species undescribed. Methods Here, we describe a new species of Scapholeberis Schoedler, 1858 (Cladocera: Anomopoda: Daphniidae: Scapholeberinae) from the Colombian Amazon Basin, collected with recently designed light traps. The description is based on detailed morphology (based on SEM and light microscopy) of parthenogenetic females, ephippial females, males, and molecular data based on the COI gene. Results Scapholeberis yahuarcaquensis n. sp. has a combination of characters present in Scapholeberis kingi Sars, 1888 and Scapholeberis armata freyi Dumont & Pensaert, 1983. These are a trilobate rostrum, with the middle lobe well developed with sides straight to relatively rounded, the presence of an elongated slit frontal head pore, a dorsal pore in the juncture of the cephalic shield and the valves, and a single denticulate membrane at the posterior rim of the valves, with stronger setae in the last third. The unique characters of the parthenogenetic females are ventral sucker with delicate triangles. Each has a filament-like projection in the lamellae’s inner side and an external section forming convex folds with denticle-like projections in the middle zone of the sucker-plate. There is a peculiar pitted sculpture in the ephippial females and a strong projection in the front of it. The male hook on the limb I with a blunt tip, a quirky lamella-like outgrow in the proximal side, and a paddle with well-developed spines scattered on its surface. The ventral sucker-lamellae in the male is much more developed than the female. The COI gene sequences showed an interspecific mean genetic divergence of 16.4% between S. yahuarcaquensis n. sp. and the closest species S. freyi from Mexico, supporting our results. A coalescence analysis and Barcode Index Number also support the new species based on the DNA sequences. New methods of collecting and integrative biology will give important support to recognize the fauna from the Amazon Basin, one of the most important sources of fresh water in the world that remains unknown in many respects.

We describe and illustrate the new species Primulina mabaensis from northern Guangdong, China. Its generic placement in the recently recircumscribed Primulina is confirmed by phylogenetic analyses of ITS and trnL-F intron-spacer DNA sequences. Primulina mabaensis is similar to P. repanda var. guilinensis, differing from the latter by its much larger flowers with corollas 2.5–3.0 cm (vs. 8–10 mm) long and corolla tubes 2.0–2.5 cm (vs. 6–8 mm) long and ca. 7 mm (vs. ca. 3 mm) in diameter at the corolla mouth. Primulina mabaensis is currently only known from limestone caves and rock surfaces of a karst tower in the Maba Man Archeology Site.

The genus Olepa is distributed in Palearctic and Oriental regions with more species in India and Sri Lanka. In the recent studies, morphological variations within the group were well established, with couple of first set of mt COI DNA barcodes for at least three species. In the present account, three new species and a new subspecies are described from the northern Western Ghats region of Maharashtra based on mt COI DNA barcode studies. Due to high morphological divergence and complete genetic homogeneity on the mt COI DNA, four morphotypes under two species are reported. Morphological and genital characters of male and female are provided along with their respective species morphotypes for the first time under this genus from India. The genitalia and the habitus of male and female are illustrated. Preliminary phylogenetic tree based on the mt COI DNA sequences available in the GenBank for the genus with the sequences for the new species also provided and discussed. Key words: new taxa, morphotype, Maharashtra, DNA barcoding, mt COI gene

Abstract We establish a new genus of planocerid polyclad, Heteroplanocera gen. nov., based on a new species, H. katoi sp. nov., collected at a depth of 245 m off the coast of the Izu Peninsula, West Pacific, Japan. Heteroplanocera gen. nov. is distinguished from other planocerid genera by the following characteristics: (i) a pair of nuchal tentacles, (ii) a muscular bulb, (iii) a pair of spermiducal bulbs (instead of a seminal vesicle), (iv) a free prostatic vesicle, (v) a pair of accessory organs with teeth, (vi) a Lang's vesicle, and (vii) the lack of a bursa copulatrix. We provide a partial sequence of the cytochrome c oxidase subunit I (COI) gene (712 bp) as a DNA barcode of the new species. Furthermore, we estimate the phylogenetic position of Heteroplanocera gen. nov. among Planoceridae based on partial sequences of COI and 16S, 18S, and 28S ribosomal DNA. Based on our findings, we discuss the evolution and function of the (i) vaginal cuticularized structure and (ii) accessory organs among planocerid flatworms.

A New Species

Within the pollinator family Syrphidae, Eumerus Meigen, 1822 is a diverse genus with over 70 species recorded in the Afrotropical Region. A new species is described here from Namibia and South Africa. Adults are small to medium size flies, with spur-like expansions in the metatarsomeres 2 and 3. DNA sequences of the Cytochrome c oxidase subunit I (COI) gene were obtained from Namibian specimens. This is only the second Eumerus species documented from Namibia, where it was recorded from The National Botanic Garden, Windhoek. The new species is compared with similar species such as Eumerus vestitus Bezzi, 1912, for which a lectotype is designated. In addition, a new and preliminary morphological concept of the Eumerus obliquus group is proposed and a key to its African species is provided.

During a DNA barcoding campaign of leaf-mining Gracillariidae from the Asian part of Russia, a new species ofPhyllonorycterHübner, feeding on the Siberian pea shrub,CaraganaarborescensLam. (Fabaceae) was discovered in Siberia. Here, this taxon is described asPhyllonorycterivanisp. n.Among Fabaceae-feedingPhyllonorycter, so far onlyP.caraganella(Ermolaev) has been known to develop onCaragana.PhyllonorycterivaniandP.caraganellashow a large divergence in morphology (external and male genitalia) and barcode region of the mtDNA-COI gene (8.6%). They feed on different host plants species and have different ranges in Russia. We show that DNA barcode data weakly supports the Fabaceae-feeding species groups. In addition, we show that morphologically (strongly) and genetically (weakly),P.ivanihas affinity to thehaasispecies group, a West Palearctic group with asymmetrical male genitalia.

Abstract This paper describes a new species of sponge-inhabiting barnacle, Neoacasta liui sp. nov., collected in Fukuoka, Kyushu, Japan. In the present study we used both the morphological examination and DNA barcode (cytochrome c oxidase I gene) to distinguish this new species from acastine species including its congeners from Neoacasta Kolbasov, 1993. Neoacasta liui sp. nov. is similar to Neoacasta glans (Lamarck, 1818) in shell morphology, but the divergence in COI gene between them reached inter-specific differences. N. liui sp. nov. is characterized by externally latticed, narrow scutum, beak-shaped tergum with wider spur, and lack of six inwardly prominent teeth on margin of basis. N. glans having an Indo-West Pacific distribution may represent a complex of cryptic species.
