Additions to the review of Chinese Enochrus,with description of a new species (Coleoptera,Hydrophilidae, Enochrinae)

A new species, Enochrus (Methydrus) limbourgi sp. n., is described from Jiangxi Province, Southeast China, and illustrated. Subgenus Enochrus s. str. Thomson, 1859 is recorded for the first time in China, based on the record of Enochrus (s. str.) melanocephalus (Olivier, 1792) from Inner Mongolia. The male of Enochrus (Hydatotrephis) liangi Jia & Zhao, 2007 is described for the first time.     

Parachironomus Lenz from China and Japan (Diptera,Chironomidae)

Members of the genus Parachironomus Lenz known from China and Japan are revised, and a key to their male adults is given. Parachironomus poyangensis sp. n. is described in this life stage. Parachironomus frequens (Johannsen) and Parachironomus monochromus (van der Wulp) are recorded from China for the first time, thus are redescribed from Chinese specimens. Parachironomus kamaabeus Sasa & Tanaka and Parachironomus toneabeus Sasa & Tanaka are new junior synonyms of Parachironomus frequens. Three Chinese or Japanese species formerly placed in Parachironomus are transferred to other genera, resulting in the new combinations Cryptochironomus inafegeus (Sasa, Kitami & Suzuki), Demicryptochironomus (Irmakia) lobus (Yan, Sæther, Jin & Wang), and Microchironomus lacteipennis (Kieffer). Chironomus sauteri Kieffer, Parachironomus kisobilobalis Sasa & Kondo and Parachironomus kuramaexpandus Sasa are removed from Parachironomus; the last of these three denotes a valid species of uncertain generic placement, the first two are nomina dubia.

Checklist of the helminth parasites of the genus Profundulus Hubbs, 1924 (Cyprinodontiformes,Profundulidae), an endemic family of freshwater fishes in Middle-America

From December 2012 to November 2014, 267 fish belonging to the family Profundulidae (representing nine of the 11 species of the genus Profundulus) were collected in 26 localities of Middle-America, across southern Mexico, Guatemala, and Honduras, comprising the distribution range of the genus, and analyzed for helminth parasites. Additionally, a database with all ten available published accounts of the helminth parasite fauna of this genus (the only genus within the family) was assembled. Based on both sources of information, a checklist containing all the records was compiled as a tool to address future questions in the areas of evolutionary biology, biogeography, ecology and phylogeography of this host-parasite association. The helminth parasite fauna of this fish group consists of 20 nominal species, classified in 17 genera and 14 families. It includes six species of adult digeneans, five metacercariae, two monogeneans, one adult cestode, three adult nematodes and three larval nematodes. The profundulid fishes are parasitized by a specialized group of helminth species (e.g. Paracreptotrema blancoi sensu Salgado-Maldonado et al. (2011b), Paracreptotrema profundulusi Salgado-Maldonado, Caspeta-Mandujano & Martínez Ramírez, 2011, Phyllodistomum spinopapillatum Pérez-Ponce de León, Pinacho-Pinacho, Mendoza-Garfias & García-Varela, 2015, Spinitectus humbertoi Mandujano-Caspeta & Moravec, 2000, Spinitectus mariaisabelae Caspeta-Mandujano Cabañas-Carranza & Salgado-Maldonado, 2007 and Rhabdochona salgadoi Mandujano-Caspeta & Moravec, 2000), representing the core helminth fauna that are not shared with other Middle-American fish species.

Material of the paederine genera Domene Fauvel, 1873 and Lathrobium Gravenhorst, 1802 from the Dayao Mountains, southern China, is examined. Eight species are identified, three of them described previously and five undescribed. Four species are described and illustrated for the first time: Domene hei Peng & Li, sp. n., Lathrobium jinxiuense Peng & Li, sp. n., Lathrobium kuan Peng & Li, sp. n. and Lathrobium leii Peng & Li, sp. n. One probably undescribed species of Lathrobium remains unnamed.     

Three new species of European Platypalpus (Diptera,Hybotidae)

Platypalpus graecoides sp. n. (Italy), Platypalpus pyreneensis sp. n. (Andorra), and Platypalpus silvahumidus sp. n. (Czech Republic) are described. All three species are illustrated and keyed. Platypalpus hallensis Grootaert & Stark, 1997 is first reported from France and Spain.     

Two new species and one new record of Parakiefferiella Thienemann, 1936 from China (Diptera,Chironomidae)

Two new species of the genus Parakiefferiella Thienemann, 1936 (Parakiefferiella fasciata Liu & Wang, sp. n. and Parakiefferiella liupanensis Liu & Wang, sp. n.) are described as adult males from China. Parakiefferiella tamatriangulata Sasa is recorded from China for the first time. A key to the known adult males of Parakiefferiella from China is presented. The generic diagnosis of male Parakiefferiella given by Cranston et al. (1989) is emended.     

Seven new hypselostomatid species from China,including some of the world’s smallest land snails (Gastropoda,Pulmonata, Orthurethra)

Seven new species of Hypselostomatidae are described from the Chinese province Guangxi: Angustopila dominikae Páll-Gergely & Hunyadi, sp. n., Angustopila fabella Páll-Gergely & Hunyadi, sp. n., Angustopila subelevata Páll-Gergely & Hunyadi, sp. n., Angustopila szekeresi Páll-Gergely & Hunyadi, sp. n., Hypselostoma socialis Páll-Gergely & Hunyadi, sp. n., Hypselostoma lacrima Páll-Gergely & Hunyadi, sp. n. and Krobylos sinensis Páll-Gergely & Hunyadi, sp. n. The latter species is reported from three localities. All other new species are known only from the type locality. Specimens nearly identical to the type specimens of Angustopila huoyani Jochum, Slapnik & Páll-Gergely, 2014 were found in a cave in northern Guangxi, 500 km from the type locality. Adult individuals of Angustopila subelevata sp. n. (shell height = 0.83–0.91 mm, mean = 0.87 mm) and Angustopila dominikae sp. n. (shell height of the holotype = 0.86 mm) represent the smallest known members of the Hypselostomatidae, and thus are amongst the smallest land snails ever reported. We note that Pyramidula laosensis Saurin, 1953 might also belong to Krobylos. Paraboysidia neglecta van Benthem Jutting, 1961, which was previously included in Angustopila, is classified in Hypselostoma.

Six species are synonymized: Sagola dilucida Broun, Sagola guinnessi Broun, Sagola longicollis Broun, Sagola longula Broun, and Sagola rectipennis Broun under Pseudoexeirarthra spinifer (Broun); Sagola insueta Broun under Sagola colorata (Broun). A lectotype is designated for Pseudoexeirarthra spinifer (Broun). A key, habitus photographs, line drawings of diagnostic characters, and distribution maps are provided for each species.     

A second species of Cheleion from Johor,Malaysia (Coleoptera,Scarabaeidae, Aphodiinae,Stereomerini)

A new species of the genus Cheleion Vårdal & Forshage, 2010, Cheleion jendeki sp. n., from Johor, Malaysia is described, illustrated and compared with the type species of the genus, Cheleion malayanum Vårdal & Forshage, 2010. Photographs of the two species are presented. The adaptation to inquilinous lifestyle of Cheleion is compared with those in other beetle groups and briefly discussed.     

Malalcahuello ocaresi gen. & sp. n. (Elateridae,Campyloxeninae)

On the validity of Epeorella Ulmer, 1939 (Ephemeroptera,Heptageniidae) with general considerations on the Heptageniidae of the Sunda Islands

The type material of Epeorella borneonia Ulmer, 1939, the sole species of the genus Epeorella Ulmer, 1939 is reinvestigated and a lectotype (male imago) is designated. Based on several morphological structures, the synonymy with Epeorus Eaton, 1881 (Rhithrogeninae) is rejected. Epeorella stat. prop., known only at the winged stages, belongs to the subfamily Ecdyonurinae, and is a probable endemic of the island of Borneo. The newly erected genus Darthus Webb & McCafferty, 2007, also endemic to Borneo and only known by one species at the nymphal stage, is shown to be a junior subjective synonym of Epeorella. The new combination Epeorella vadora (Webb & McCafferty, 2007) is proposed for the species. The distribution of known heptageniid species from the Sunda Islands is discussed.     

New species of Daidalotarsonemus and Excelsotarsonemus (Acari,Tarsonemidae) from the Brazilian rainforest

Three new species of Tarsonemidae, Daidalotarsonemus oliveirai Rezende, Lofego & Ochoa, sp. n., Excelsotarsonemus caravelis Rezende, Lofego & Ochoa, sp. n. and Excelsotarsonemus tupi Rezende, Lofego & Ochoa, sp. n. are described and illustrated. Measurements for these species are provided, as well as drawings, phase contrast (PC), differential interference contrast (DIC) and low temperature scanning electron microscopy (LT-SEM) micrographs. Some characters, which have not been used or clearly understood, are described herein. Biological, ecological and agricultural aspects about the role of these species in the rainforest and its surrounding environment are briefly discussed.
