A New Species

Seventeen species of tardigrades were found in this study. All species are new records for Guizhou Province, including two new records for China (Echiniscus perviridis and Doryphoribius zappalai) and one (Doryphoribius huangguoshuensis sp. nov.) new for science. The new species differs from the most similar species of the genus Doryphoribius mainly by different configuration of gibbosities on dorsal side of the body (configuration 4, 4, 4, 4, 4, 4, 4, 2, 2 in the new species; 2, 2, 2, 2, 2, 2, 2 in D. dupliglobulatus; 4, 4, 4, 4, 4, 4, 4, 2, 2, 3 in D. gibber; 6, 4, 6, 4, 6,4, 4, 2 in D. zyxiglobus).

A New Species

During ArcticNet surveys aboard ‘CCGS Amundsen’ in 2011, several subtidal stations located in Canadian Archipelago were sampled in order to study the composition of their benthic communities. Among the abundant material sampled, several specimens of rare polychaete species were found. Examination of this material showed four species not previously recorded in the area, and a new species described herein. Descriptions of these specimens are given in this work.Ophelina brattegardiKongsrudet al., 2011 is characterized by a body composed of 27–28 chaetigers, by having the parapodia of the last four chaetigers shifted to the ventral side of the body, and by lacking branchiae in mid-body chaetigers.Macrochaeta polyonix Eliason, 1962 is unique within the genus in having several (instead of one or two) compound neurochaetae in anterior parapodia.Chaetozone acutaBanse & Hobson, 1968 is characterized by having spines from anterior third of the body and arranged in bundles composed of just a few chaetae.Chaetozone jubataChambers & Woodham, 2003 can be distinguished from similar species by having very long capillary chaetae from chaetiger 2 or 3. Finally,Dialychone hervyaen. sp. is characterized by bearing four pairs of radioles with narrow flanges, by the bilobed tip of its first peristomial ring that projects beyond the collar, and by the paleate thoracic notochaetae bearing long mucros.

During a survey of araneogenous fungi from Guizhou Province, China, a new species, Akanthomyces araneogenum, was isolated from a spider, Araneus sp. It differs from other Akanthomyces species by its spider host, Isaria-like conidiogenous structure, and mostly globose and smaller conidia (1.6–2.2 μm). Multi-locus (ITS, LSU, RPB1, RPB2 and TEF) phylogenetic analysis confirmed that A. araneogenum is distinct from other species. The new species is formally described and illustrated, and compared with similar species.

Alopecosa volubilis n. sp. is described from Korea and is differentiated from other species in Alopecosa Simon, 1885 by morphological characteristics, such as three retromarginal teeth of chelicera, smaller body size, and the presence of a distinct tip of the median apophysis. The pedipalpal sclerites and somatic characters of two similar species, A. moriutii Tanaka, 1985 and A. hokkaidensis Tanaka, 1985, are compared with those of the new species. An illustration of the body and scanning electron microscope (SEM) pictures of the pedipalpal organ are provided.

AbstractA new species of Skrjabinolecithum (Digenea: Waretrematinae), Skrjabinolecithum pyriforme n. sp., has been found in the intestines of Liza haematocheila and Mugil cephalus from the Primorsky Region, Russia. These worms differ from S. vitellosum and S. lobolecithum by the presence of two caeca, as do S. spasskii, S. indicum and S. bengalensis. These species differ morphologically from S. pyriforme n. sp. by a number of features, including body width, oral sucker, pharynx, eggs and ratio of length and width of the body. The most similar species to S. pyriforme n. sp. is Platydidymus flecterotestis (Zhukov, 1971) with some differences in maximal body length, testis and egg sizes. The results of molecular analysis confirmed that this new species belongs to Skrjabinolecithum on the basis of close relationships with S. spasskii-type species.

A new species of Lamellarea (Oribatida, Lamellareidae) is described from hick twigs of southern live oak in Florida, U.S.A. (part of the Neotropical region). Lamellarea americana sp. nov. differs from most similar species, Lamellarea digitata and L. forceps by the ventrally inserted lamellar setae, the number of genital setae, the length of interlamellar setae, and the body size. Remarks on generic diagnosis and distribution of Lamellarea are presented.

Abstract A new species, Skrjabinopsolus nudidorsalis sp. nov. is described from the sterlet Acipenser ruthenus, caught in the River Volga basin (Russia). This species differs from previously described congeners by the absence of vitelline follicles on the dorsal side of the body. The complete 18S rRNA and partial 28S rRNA gene sequences obtained for S. nudidorsalis are the first molecular data for the family Deropristidae. The results of phylogenetic analysis indicate that Deropristidae is sister to the Monorchiidae + Lissorchiidae group. The results of the phylogenetic study contradict the current taxonomic hypothesis that Deropristidae belongs to the superfamily Lepocreadioidea and allow inclusion of this family in Monorchioidea. The morphological similarity of deropristids to other monorchioids is recognizable from the presence of a bipartite internal seminal vesicle, spinous cirrus and a voluminous, armed metraterm.

A new species of the genus Megophrys is described from Guizhou Province, China. Molecular phylogenetic analyses based on mitochondrial DNA and nuclear DNA sequences all strongly supported the new species as an independent clade sister to M. minor and M. jiangi. The new species could be distinguished from its congeners by a combination of the following characters: body size moderate (SVL 43.4–44.1 mm in males, and 44.8–49.8 mm in females; vomerine teeth absent; tongue not notched behind; a small horn-like tubercle at the edge of each upper eyelid; tympanum distinctly visible, rounded; two metacarpal tubercles on palm; relative finger lengths II < I < V < III; toes without webbing; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between tympanum and eye when leg stretched forward; in breeding males, an internal single subgular vocal sac in male, and the nuptial pads with black spines on dorsal surface of bases of the first two fingers.

Minibiotus gumersindoi n. sp. is described. This species was collected on a granite mountain range in Sierra de Guadarrama (Bustarviejo valley, Embalse de la Jarosa and Cercedilla, Madrid, Spain) and on a volcanic island in Parque Natural Caldera de Taburiente (La Palma, Canary Islands, Spain). This new species is characterized by a unique set of characters in the genus: the presence of large round pores in the body and a larger round pore at the distal part of each leg. New records of several known species, for Madrid, Canary Islands and/or the Iberian Peninsula are given.
