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.

Living Species

Two new deep-living species of the genus Bargmannia (Siphonophorae, Physonectae, Pyrostephidae) are described based, almost exclusively, on the nectophores of single specimens collected by ROVs off the west coast of California. The nectophores of B. stenotes sp. nov. were relatively small, up to 11.4 mm in length and, in the preserved condition had very narrow nectosacs. There was a marked bend in the distal part of the preserved nectophore, resulting in the ostium opening upwards. The mature nectophores of B. profunda sp. nov. were almost twice as long as those of B. stenotes and were characterised by the fact that the lower lateral ridges did not join, distally, with the meso-lateral ones. This feature also was present in smaller nectophores of B. amoena but those of B. stenotes, at that stage, did not have a mouth-plate.

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.

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.

Two new species, Tubificoides fraseri and T. motei, are described and three other species are placed in synonymy: T. foliatus with T. wasselli, T. coatesae with T. brownae, and T. maureri with T. diazi. Most of these decisions refer to species that have been described separately but published jointly by the author and H. R. Baker. The original descriptions were based on separate east and west coast collections from North America that contained species that seemed separable on the basis of the material available but that now appear to belong to fewer widely distributed species. Five other Tubificoides species that lack hair setae are redescribed. Several of the species in this part of the genus seem to be widely distributed in contrast to those members of the genus with hair setae in the dorsal bundles.

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.

Occigamasus n. gen., O. lindquisti n. sp. and O. makarovae n. sp. from Vancouver Island (Canada) and Oregon (U.S.A.) are described. Five other new species and their sites are noted but not enough specimens were available for adequate descriptions. Cycetogamasus californicus (Banks) sensu Hennessey and Farrier, 1988 is transferred to Occigamasus as a new combination.
