Two new free-living nematode species of Setosabatieria (Comesomatidea) from the East China Sea and the Chukchi Sea

Two new free-living marine nematode species of the genus Setosabatieria from the sandy intertidal zone of Xiamen, in the East China Sea and a shallow water area in the Chukchi Sea, Arctic Ocean are described and illustrated. Setosabatieria longiapophysis sp. nov. is characterized by four longitudinal files with 7–9 cervical setae per file, 15–16 minute papillate precloacal supplements and relatively long straight apophyses of gubernaculum. Setosabatieria major sp. nov. is identified by its relatively large body of 2701–3144 µm, the number (10–11) of cervical setae per file, 26–28 minute papillate precloacal supplements and spicules with a central septum at both the proximal and distal end. A pictorial identification key to all known species of Setosabatieria is provided.

Two new species of Lauratonema (Nematoda: Lauratonematidae) from the intertidal zone of the East China Sea

Two new species of free-living marine nematodes of the genus Lauratonema Gerlach, 1953 from an intertidal sandy beach of the East China Sea are described and illustrated. Lauratonema macrostoma sp. nov. is characterized by a spacious buccal cavity, depth 2.1–2.3 times width; cup-shaped amphids; small blade-like spicules (14–16 µm long, 0.55–0.65 anal or cloacal body diameter [a.b.d.]) and unequal length of outer labial setae and cephalic setae (13–17 µm and 9–12 µm respectively). Lauratonema dongshanense sp. nov. can be distinguished by the small buccal cavity with a strong cuticularized transverse strip structure; cup-shaped amphids; small blade-like spicules (14–15 µm long, 0.58–0.67 a.b.d.), unequal length of outer labial setae and cephalic setae (8–10 µm and 5–7 µm respectively); the presence of a small precloacal papilla. A dichotomous key for the genus Lauratonema is given.

A new damsel-dragonfly from the Mesozoic of China with a hook-like male anal angle (Odonata: Isophlebioptera: Campterophlebiidae)

A new genus and species of campterophlebiid dragonfly, Angustiphlebia mirabilis gen. nov. et sp. nov., is described from the Jiulongshan Formation in China. It has some remarkable venational structures, i.e. a hypertrophy of the male hind wing anal angle, a quite long gaff, and a secondary branch of the anal anterior near subdiscoidal cell in hind wing, supporting the hypothesis of a sister-group relationship with the genus Oreophlebia. These new data will help to solve the phylogenetic relationships within the Campterophlebiidae. http://www.zoobank.org/urn:lsid:zoobank.org:pub:16E602E6-3567-44D7-BF64-95A6597E55DE     

Two new free-living marine nematode species of Xyalidae (Monhysterida) from the Yellow Sea,China

Two new species of free-living marine nematodes Paramonohystera eurycephalus sp. nov. and Steineria sinica sp. nov. from the Yellow Sea, China are described. Paramonohystera eurycephalus sp. nov. is characterized by relatively wide head diameter (33 μm in width), large cup-shaped buccal cavity; presence of numerous long cervical setae; amphidial fovea 18–20 μm in diameter; spicules slender, arcuate, 3.1–3.2 anal body diameter; gubernaculum tubular with a distal hook; five to six minute precloacal supplements. Steineria sinica sp. nov. is characterized by eight groups of three subcephalic setae at almost same level as cephalic setae; eight groups of two long cervical setae situated between subcephalic setae and amphidial fovea; amphidial fovea round, 35% of corresponding body diameter, about one head diameter from anterior end; spicules slender, cephalate proximally and taper distally; gubernaculum pipe-shaped with dorsocaudal apophysis; tail conico-cylindrical with three long terminal setae.     

First record of the genus Koreanurina Najt and Weiner (Collembola: Neanuridae: Pseudachorutinae) from China,with description of two new species from Changbai mountain

The genus Koreanurina Najt and Weiner, 1992 is recorded for the first time from China. It is redefined and its similarity with the subfamily Caputanurininae is stressed. Two species are described from Changbai Mountain in North-East China: Koreanurina weinerae sp. nov. and K. alba sp. nov. The first species differs from the other species of the genus, mostly by its post-antennal organ located on the lateral edge of head (versus dorsolaterally), its central plate on head wider and the presence of only 1 + 1 chaetae on Th I (versus 2–3 + 2–3). K. alba sp. nov. differs from the other species of the genus mostly by the absence of body pigment, and the presence of only 1 + 1 chaetae posteriorly to the furcal rest (versus 2 + 2).

A new genus and two new species of Pudeoniscidae Lemos de Castro 1973 (Crustacea: Isopoda: Oniscidea) from Brazil

To date, the family Pudeoniscidae includes six species and three genera, Pudeoniscus, Brasiloniscus and Iansaoniscus, with distributions restricted to Brazil. Here, we redefine the family Pudeoniscidae based on the discovery of a new genus and two new species, Oxossioniscus pataxo sp. nov. and Oxossioniscus akoko sp. nov., from the Brazilian Atlantic forest in the state of Bahia, and on the examination of Pudeoniscus birabeni and Pudeoniscus obscurus. Moreover, P. obscurus is re-described and new records are provided for P. birabeni.

The morphological and molecular analyses of a new South American urban tardigrade offer new insights on the biological meaning of the Macrobiotus hufelandi group of species (Tardigrada: Macrobiotidae)

Worldwide knowledge of tardigrade fauna is still limited, and many areas such as South America are not well studied. The collection of new substrates in Argentinean urban areas provided an opportunity to describe the new tardigrade species Macrobiotus kristenseni sp. nov. This species has been studied with an integrative taxonomic approach, analysing its morphology by light and scanning electron microscopy, and considering two genes (cox1 and 18S rRNA) for DNA barcoding and phylogenetic purposes. The species belongs to the Macrobiotus hufelandi group of species, and it is characterized by egg processes in the shape of elongated cones with truncated and enlarged apexes, and by a high genetic distance with respect to closely related species (cox1: 18.2–33.4%). Morphological and molecular data show that the Macrobiotus hufelandi group of species has to be considered a true biological entity; one of the more widespread tardigrade lineages in continental environments. http://www.zoobank.org/urn:lsid:zoobank.org:pub:2CA51ABA-5570-4AFB-8182-CE499D97B0F1
