A review of the genus Raveniola (Araneae, Nemesiidae) in China, with notes on allied genera and description of four new species from Yunnan

The Chinese representatives of Raveniola Zonstein, 1987 are currently recognized to comprise seven species. Four new species - Raveniola montanasp. n. (♂♀), Raveniola shangrilasp. n. (♂), Raveniola songisp. n. (♂) and Raveniola yunnanensissp. n. (♂) - are described from the highlands of Yunnan Province, China. According to some characters (shape of the palpus, palpal tibia and tibia I in males) they can be placed together with Raveniola hebeinica Zhu, Zhang & Zhang, 1999 and with Raveniola guangxi (Raven & Schwendinger, 1995), comb. n., transferred here from Sinopesa Raven & Schwendinger, 1995. The current generic position of Raveniola xizangensis (Hu & Li, 1987) is confirmed. Other Chinese nemesiids referred previously to Raveniola are transferred to Sinopesa: Sinopesa chinensis (Kulczyński, 1901), comb. n., Sinopesa sinensis (Zhu & Mao, 1983), comb. n. and Sinopesa chengbuensis (Xu & Yun, 2002), comb. n.

A New Species of Chigger Mite (Acari: Trombiculidae) from Rodents in Southwest China

This paper describes a new species of chigger mite (Acari: Trombiculidae), Gahrliepia cangshanensis n. sp., from rodents in southwest China. The specimens were collected from Yunnan red-backed voles, Eothenomys miletus (Thomas, 1914), and a Chinese white-bellied rat, Niviventer confucianus (Milne-Edwards, 1871) in Yunnan Province. The new species is unique mainly in its number of dorsal setae (n=21), and it has the following features: fT (formula of palpotarsus)=4B (B=branched), fp (formula of palpal seta)=B/N/N/N/B (N=naked), a broad tongue-shaped scutum with an almost straight posterior margin, and 17 PPLs (posterior posterolateral seta) with a length of 36-43 µm. This chigger mite may also infect other rodent hosts and may be distributed in other localities.

Descriptions of Eumonhystera borealis n. sp., Sphaerolaimus occidentalis n. sp., and a Redescription of S. gracilis de Man 1876 (Nemata) from Bothnian Bay,Baltic Sea

The free-living nematodes Eumonhystera borealis n. sp., Sphaerolaimus occidentalis n. sp., and S. gracilis de Man 1876 from Bothnian Bay in the northern Baltic Sea are described and illustrated. Eumonhystera borealis n. sp. differs from other species by its small body size (314-393 μm), narrow body (a = 37-49), and large anterior amphids. In Sphaerolaimus occidentalis n. sp. the amphids are posterior to the buccal cavity, and it differs from other similar species by having two sclerotized rings in the posterior part of the buccal cavity. An intersex is reported for S. gracilis. Sphaerolaimus gracilis is cannibalistic or a predator of other species, with a preference for E. borealis n. sp. Sphaerolaimus occidentalis n. sp. coexists with S. gracilis at depths of 80 m but not at 12 m.     

Euastacus morgani sp. n., a new spiny crayfish (Crustacea, Decapoda, Parastacidae) from the highland rainforests of eastern New South Wales, Australia

Euastacus morgani sp. n., is described from a highland, rainforest site in Bindarri National Park, in eastern New South Wales, Australia. Euastacus morgani is found living sympatrically with two more common species, Euastacus dangadi Morgan, 1997 and Euastacus neohirsutus Riek, 1956.

A new sexannulate species of Orobdella (Hirudinida, Arhynchobdellida, Orobdellidae) from Yakushima Island, Japan

A new sexannulate species of the genus Orobdella Oka, 1895, Orobdella mononokesp. n., is described on the basis of five specimens collected from Yakushima Island, Japan. Orobdella mononokesp. n. differs from other sexannulate Orobdella species in its possessing the following combination of characters: dorsal surface bicolor in life, I-XIII, XXVII and caudal sucker grayish purple, XIV-XXVI amber, male gonopore at XI c11/c12, female gonopore at XIII b2, 8 + 1/2 between gonopores, tubular but bulbous at junction with crop gastroporal duct, epididymides in XV-XIX, and atrial cornua ovate. Phylogenetic analyses using nuclear 18S rDNA and histone H3, and mitochondrial COI, tRNA(Cys), tRNA(Met), 12S rDNA, tRNA(Val) and 16S rDNA markers show that Orobdella mononokesp. n. is closely related to Orobdella esulcata Nakano, 2010 from Kyushu, Japan, and two species, Orobdella dolichopharynx Nakano, 2011 and Orobdella shimadae Nakano, 2011, from the Ryukyu Archipelago, Japan.
