Two New Species of Photosymbiotic Ascidians of the GenusDiplosomafrom the Ryukyu Archipelago, with Partial Sequences of the COI Gene

We describe two new species of the millipede genus Riukiaria from two islands of the Ryukyu Archipelago: R. maculata sp. n. from Tane-ga-shima, northern Ryukyus, and R. mundyi sp. n. from Yonaguni-jima, the southwesternmost member of the Yaeyama Island Group. Both species show the simple forceps-like male gonopod structure typical for the genus, but they are readily distinguishable from other members by their unique color patterns. We have also compiled a list of species in the genus described up to now.

Two new species of feather mites from the superfamily Analgoidea are described from the grey-headed woodpecker, Picus canus, in Korea: Neopteronyssus koreanus sp. nov. (Pteronyssidae) and Proterothrix picinus sp. nov. (Proctophyllodidae: Pterodectinae). Feather mites of the genera Neopteronyssus Mironov, 2002 and Proterothrix Gaud, 1968 are described for the first time in Korea. Morphological descriptions of both new species are complemented with partial sequences of their mitochondrial cytochrome c oxidase subunit I (COI) gene as DNA barcodes.

Sexannulate Orobdella leech, Orobdella ijimai, is redescribed based on newly collected specimens from the type locality, Nikko, Tochigi Pref., Japan, since this species was originally described based on limited number of characters. In addition, two new sexannulate species, Orobdella dolichopharynx sp. nov. from Amamioshima Island in the Ryukyu Archipelago, Japan, and Orobdella shimadae sp. nov. from Okinawajima Island also in the Ryukyu Archipelago, are described. They resemble O. ijimai in the annulation of mid-body somites, but they differ from the latter in the annulation of somite VIII, position of gonopores, the lack of gastropore, the length of pharynx, the shape of gastroporal duct, and the morphology of male genital organ. Two new Orobdella species differ from each other in the annulation of somite VII, the position of gonopores, and the shape of gastroporal duct. In accordance with the two new species, the diagnosis of Orobdella is slightly emended.

Two new black fly species, Simulium (Gomphostilbia) dinakarani sp. nov. and Simulium (Gomphostilbia) krishnani sp. nov. are described based on reared adult, pupal and larval specimens collected from the Western Ghats of India. These two new species are placed in the Simulium batoense species-group of the subgenus Gomphostilbia Enderlein. The morphological characters of two new species are compared with other related species of batoense species-group in India. The COI gene has successfully differentiated these two new species from its allies, S. (G.) panagudiense and S. (G.) takaokai of the batoense species group and the phylogenetic analysis by using COI gene sequences supporting its morphological classification.

First Time

The species-rich giant pill-millipedes (Sphaerotheriida) often represent a microendemic component of Madagascar’s mega-invertebrate fauna. Of the chirping genus Sphaeromimus de Saussure & Zehntner, 1902, ten species have been described. Here, we describe two new species of Sphaeromimus integratively, combining light microscopy, scanning electron microscopy, DNA barcoding and micro-CT technology for the first time in a taxonomic description of a giant pill-millipede. S. kalambatritra sp. nov. and S. midongy sp. nov. are the first giant pill-millipedes collected and described from the mountainous rainforests of Kalambatritra and Midongy. Both species show island gigantism compared to their congeners. Our analysis of the mitochondrial COI gene shows that the two species are related to one another with a moderate genetic distance (9.4%), while they are more closely related to an undetermined specimen from the forest of Vevembe (6.3% and 8.4%). They stand in a basal position with S. ivohibe Wesener, 2014 and S. musicus (de Saussure & Zehntner, 1897). The four aforementioned species share a high number of stridulation ribs on the male harp. Our micro-CT analysis provides a look into the head of S. kalambatritra sp. nov. and shows that non-destructive CT methods are a useful tool for studying the inner morphology of giant pill-millipedes.

Worker Caste

Two new species of Leptanilloides are described: L. copalinga Delsinne & Donoso sp. nov., and L. prometea Delsinne & Donoso sp. nov., based on workers collected in the leaf litter and soil of the Andes of southern Ecuador. Both species belong to the L. biconstricta species-group (formally diagnosed here). The metatibial gland, considered a synapomorphy for Dorylinae, is observed in L. prometea sp. nov. but seems absent in L. copalinga sp. nov. We provide a COI DNA barcode for both species and a revised key for the worker caste of all known species in the genus. We also describe a single male identified as a potential new Leptanilloides species on the basis of morphology. Furthermore, its mitochondrial COI gene sequence does not match any previously barcoded species. However, we refrain from giving it a specific name because of our lack of knowledge about the worker caste. So far, half of the 14 Leptanilloides species have been discovered above 1500 m in the mountain forests or páramos of the Ecuadorian Andes, confirming, if needed, the biological significance of these threatened habitats.

Two new species of marine Platyhelminthes, Microstomum laurae sp. nov. and Microstomum edmondi sp. nov. (Macrostomida: Microstomidae) are described from the west coast of Sweden. Microstomum laurae sp. nov. is distinguished by the following combination of characters: rounded anterior and posterior ends; presence of approximately 20 adhesive papillae on the posterior rim; paired lateral red eyespots located level with the brain; preoral gut extending anterior to brain and very small sensory pits. Microstomum edmondi sp. nov. is a protandrous hermaphrodite with a single ovary, single testis and male copulatory organ with stylet. It is characterized by a conical pointed anterior end, a blunt posterior end with numerous adhesive papillae along the rim, and large ciliary pits. The stylet is shaped as a narrow funnel with a short, arched tip. In addition, the first records of fully mature specimens of Microstomum rubromaculatum von Graff, 1882 from Fiskebäckskil and a phylogenetic analysis of Microstomum Schmidt, 1848 based on the mitochondrial cytochrome oxidase I (COI) gene are presented.

Holotype Male

Ten species of Cephennomicrus are currently known to occur in Japan, predominantly in the Ryūkyū Archipelago. These extremely small beetles (adults of Japanese species do not exceed 1.2 mm) are rarely collected, and their true diversity may be in fact much greater. Two more species are described in the present study: C. aji sp. n. inhabiting Okinawa island, and C. ushimanus sp. n. found on Amami Ôshima island. Cephennomicrus aji has the smallest adults of all Japanese Scydmaeninae; the holotype male measures merely 0.66 mm of body length. The distribution of Japanese Cephennomicrus species is summarized, with the aedeagus of each species illustrated on the distribution map, to facilitate identifications and further study on this broadly distributed but poorly known cephenniine genus.

The genus Svistella contains 8 species worldwide with 7 recorded from China. In this study, we reconstructed the gene tree based on COI gene, and reported two new species, S. wuyong He sp. nov. and S. malu He sp. nov. The new species differs from allied species in color, male genitalia, songs and molecular study. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).
