Ectocotyla hirudo (Levinsen, 1879) is redescribed and recorded for the first time from the gills and branchial chambers of Chionoecetes opilio and Hyas araneus. Problems arising from previous descriptions are resolved through comparison of freshly collected material, at different times of the year, with type material of Coleophora sp. and the type material of E. paguri Hyman, 1944, both of which are shown to be identical to the present material. Accordingly, E. paguri Hyman, 1944 is regarded as a junior synonym of E. hirudo (Levinsen, 1879). A new species, E. multitesticulata, is described and recorded also from C. opilio and H. araneus. Ectocotyla multitesticulata differs from E. hirudo primarily in the larger size of the worm, the greater number and size of the testes, the size of the egg capsule, and in the differences of the karyotype. The genus Ectocotyla is discussed in relation to closely related genera (Peraclistus, Minona, and Preminona) in the family Monocelididae. Key words: turbellarian systematics, Proseriata, Monocelididae, Ectocotyla, crab commensal

The spider genus Austrochilus comprises only six species known from Chile and Argentina. Here, we describe a new species, Austrochilus parwis sp. n., based on a single male and several females. The new species was found in Chile (Region IX) and, based on characters in the male and female genitalia, seems to be closely related to A. forsteri Grismado, Lopardo & Platnick, 2003. The female genitalia were investigated using X-ray microscopy, revealing for the first time the internal organization of austrochiline female genitalia. Furthermore, we provide a comparative documentation of the male genitalia of austrochilines based mainly on type material, and comment on the recently proposed nomenclatorial changes to the family name Austrochilidae.

This work includes taxonomic data on two species of oribatid mites of the family Otocepheidae from Malaysia. A new species of the genus Fissicepheus is described. Fissicepheus parastriganovae n. sp. differs from Fissicepheus striganovae Ermilov and Anichkin, 2014 by body ornamentation, length of interlamellar and notogastral setae and morphology of genital plates. The species Leptotocepheus murphyi (Mahunka, 1989) is recorded in Malaysia for the first time. A supplementary description of this species which was originally described from Singapore is given on the basis of the Malaysian specimens. The main morphological traits for L. murphyi are summarized.

Recently, we (Akkari & Enghoff 2011) described a new species of the genus Rharodesmus Schubart, 1960, discussing the taxonomic state of the family Pyrgodesmidae and providing notes on the four genera occurring in the west Palaearctic area. However, we failed to present details on the holotype of the new species, which we now provide in this note in order to make the species name available. Thus, we describe here the new species Rharodesmus tabarkensis Akkari & Enghoff by reference to the full description given in Akkari & Enghoff (2011) with the following information on the type material: Holotype ♂, TUNISIA, NW, Jendouba Governorate, Tabarka, N36°57.8, E8°44.6, alt. < 40 m, coastal slope below the Genoese fort, under stones, 9.iii.2009, N. Akkari & H. Enghoff leg. (Natural History Museum of Denmark, Zoological Museum, University of Copenhagen, ‒ ZMUC); Paratypes: 12 ♂♂, 8 ♀♀, 14 juveniles, same locality and date as holotype, N. Akkari & H. Enghoff leg. (ZMUC).

Yara marmontsedu, a new species in the family Hydroscaphidae (Coleoptera: Myxophaga), is described and illustrated. Specimens of Y. marmontsedu were collected at the Pijibay Creek, tributary of the Mico River in Chontales, Nicaragua. The immature stages are described and illustrated for the first time for a species of Yara. This is a contribution to the knowledge of the water beetle fauna of Nicaragua.

The oribatid mite family Astegistidae is represented in Mongolia by four species in two genera. A new species, Cultroribula taigagica sp. nov., collected from cool temperate forests in Northern Mongolia is described based on adults. In addition, three known species, Astegistes pilosus (C.L. Koch, 1840), Cultroribula dentata Willmann, 1950 and Cultroribula vtorovi Krivolutsly, 1971 are recorded for the first time from Mongolia, which are redescribed along with data on their distribution and ecology. A key to Mongolian species of Astegistidae is given.

Quill mites (Acariformes: Prostigmata: Syringophilidae) parasitizing waxbills of genus Estrilda Swainson (Aves: Passeriformes: Estrildidae) from the Sub-Saharan region are studied for the first time. Among them, a new species, Syringophiloidus estrildus sp. nov., is described and new host species for Neosyringophilopsis lonchurus Skoracki, 2008, Neoaulonastus oryzivorus (Skoracki, 2011) comb. nov., and Picobia lonchurae Skoracki et al., 2016 are recorded. In our study, we examined 120 specimens belonging to seven of the 16 (44%) species of the genus Estrilda. The prevalence of infestation by syringophilid species varied from 3.7 to 25%. The host and habitat (feather type) specificity are discussed.

A phylogenetic analysis of the Mycetophiliformia (= Sciaroidea) was performed to determine the relationships among its families and to place the following genera of uncertain position in the system: Heterotricha, Ohakunea, Colonomyia, Freemanomyia, Rhynchoheterotricha, Chiletricha, Afrotricha, Anisotricha, Kenyatricha, Nepaletricha, Sciarosoma, Sciaropota, Insulatricha, Cabamofa, Rogambara, and Starkomyia. Eratomyia n. gen. is described based on a new species from Ecuador. Colonomyia brasiliana sp.n. and Colonomyia freemani sp.n. are described respectively from southern Brazil and Chile. The male of Cabamofa mira Jaschhof is described for the first time. A total of 64 terminal taxa and 137 transformation series (with 202 characters) were included in the data matrix, with a number of new features from thoracic morphology. Willi Hennig’s 1973 system for the higher Bibionomorpha was adopted using the name Mycetophiliformia for the Sciaroidea. The Mycetophiliformia are monophyletic. The family Cecidomyiidae appears as the sister group of the remaining Mycetophiliformia, followed by the Sciaridae. In the preferred topology, the Rangomaramidae appear as the group sister of a clade consisting of (Ditomyiidae + Bolitophilidae + Diadocidiidae + Keroplatidae) and of (Lygistorrhinidae + Mycetophilidae). The topology within the Rangomaramidae is (Chiletrichinae subfam. n. (Heterotrichinae subfam. n. ((Rangomaraminae + Ohakuneinae subfam. n.))). The Chiletrichinae include the genera Kenyatricha, Rhynchoheterotricha, Insulatricha, Chiletricha, and Eratomyia n. gen. Heterotrichinae and Rangomaraminae are monotypic. The subfamily Ohakuneinae includes Ohakunea, Colonomyia, Cabamofa, and Rogambara. The positions of Freemanomyia, Loicia, Taxicnemis, Sciaropota, Starkomyia, Anisotricha, Nepaletricha, and Sciarosoma are considered. Afrotricha might belong to the Sciaridae. The similarities used by many authors to gather the Sciaridae and Mycetophilidae in a clade are shown to be a combination of plesiomorphies and homoplasies.

The family Micronoctuidae and the genus Micronoctua Fibiger, 1997 are reported from the Russian Far East and neighbouring countries for the first time. The family is represented in the region by two species in the genera Mimachrostia Sugi, 1982 and Micronoctua both occurring in Russian Far East, Korea, China and Japan. The northern distribution limit of the family Micronoctuidae is the middle of the Amur River (50°31΄N, 137°035΄E), reached by Mimachrostia fasciata Sugi, 1982. The new species, Micronoctua occi, sp. n. is described from Russian Far East, the Korean peninsula, China and the Tsushima Islands of Japan. The male and female genitalia are illustrated and compared with those of Micronoctua karsholti. Distribution maps for the two species are presented.
