The genera Preptetos Pritchard, 1960 and Neopreptetos Machida, 1982 are redefined. The following species are described and/or recorded from marine fishes. From the Great Barrier Reef: Preptetos caballeroi Pritchard, 1960 in Naso annula-tus, N. brevirnslris and N. vlamingii·, P. xesuri (Yamaguti, 1940) in Zebrasoma veliferum and Z. scopas; Preptetos cannoni Barker, Bray et Cribb, 1993 in Siganus dolialus and S. fuscescens', Preptetos laguncula sp. n. in Naso unicornis (type-host); P. impar sp. n. in Lutjanus erythropterus (type-host) and L. malabaricus·, Neopreptetos arusettae Machida, 1982 in Pomacanthus semicirculatus·, and N. kurochkini (Toman, 1989) in Chaetodontoplus meredithi. From southwestern Australia: Preptetos rotto sp. n. in Nelusetta ayraudi (type-host), Neosebastes pandus, Oplegnathus woodwardi and Pagrus auratus. The new combination Preptetos trulla (Linton, 1907) (originally Distomum then Lepocreadium) is made and the species Lepocreadium areolatum (Linton, 1900) is considered likely to belong in Preptetos.
Phonochorion Uvarov (Orthoptera: Tettigoniidae: Phaneropterinae) is a little known genus consisting of three species: Ph. satunini, Ph. artvinensis and Ph. uvarovi. The objective of this study is to conduct a thorough distributional, taxonomic and systematic revision of the genus Phonochorion using both bioacustic and external morphological characters. Field surveys indicate that the genus is distributed from the Trabzon region of Turkey to the Khulo province of Georgia however the exact limit of the eastern distribution of the genus remains unknown. Phonochorion species occur only on the northern slopes of the East Black Sea and Lesser Caucasus Mountains. The Coruh Valley, which seprates the East Black Sea and Lesser Caucasus Mountain ranges, seems to be an effective physical and climatic barrier and determines the distribution of these species. Ph. uvarovi can clearly be distinguished from Ph. satunini and Ph. artvinensis by the calling songs of males and external morphological characters. Ph. artvinensis and Ph. satunini differ in several taxonomic characters but the males have virtually identical calling songs. From a character evolution perspective, although geographically more distant, Ph. satunini is more closely related to Ph. uvarovi than Ph. artvinensis. Morphological similarities in several characters indicate Phonochorion to be most closely related to Polysarcus zacharovi and the Poecilimon heroicus-group. Within the genus Phonochorion, song structure and morphological characters clearly indicate Ph. uvarovi to be the basal taxon.
The species Beludzhia phylloteliptera Rohdendorf is redescribed from adult males and females as well as all larval instars collected in the United Arab Emirates. The morphology of the first instar larva is strikingly similar to that of Dolichotachina marginella (Wiedemann) and Phylloteles pictipennis Loew, all of which are here documented for the first time. These three generic representatives share several character states, which are probably plesiomorphic relative to the condition observed in other miltogrammine larvae, but the uniquely shaped, slender mouthhook, a cushion- or pad-like lobe behind the maxillary palpus (cheek organ), the antero-ventral segmental prolegs of the first instar larva, and the integumental warts of the third instar larvae, are shared character states not known from any other species of Sarcophagidae. Beludzhia Rohdendorf is therefore placed with Dolichotachina Villeneuve and Phylloteles Loew in the tribe Phyllotelini.
The genus Agnippe Chambers, 1872 in the Palaearctic Region is revised. Sixteen species are recognized as valid. Three new synonyms are established: A. conjugella Caradja, 1920 = A. haberlandii Amsel, 1961 syn. n., A. lunaki Rebel, 1941 = A. penicillata Amsel, 1961 syn. n., A. kuznetzovi Lvovsky & Piskunov, 1989 = A. zhengi Li, 1993 syn. n. Four new species are described: A. echinuloides sp. n. (S Ural, Tuva, Transbaikalia, Mongolia), A. turanica sp. n. (Uzbekistan, Kazakhstan), A. deserta sp. n. (Uzbekistan) and A. separatella sp. n. (S Iran). Description of all the species and an identification key are presented, accompanied by illustrations of the adults, and male and female genitalia.
The Poecilimon ornatus group has an exclusively European distribution and includes the largest species in the genus. A revision of the taxa belonging to this group in Bulgaria and Macedonia (Central and Eastern Balkan Peninsula) is presented. Nine taxa described from Bulgaria are synonymised with 3 previously known species, as follows: Poecilimon ornatus (= P. mistshenkoi marzani, syn. n., P. mistshenkoi tinkae, syn. n., P. mistshenkoi vlachinensis, syn. n.), P. affinis s. str. (= P. mistshenkoi mistshenkoi, syn. n., P. affinis ruenensis, syn. n., P. affinis rilensis, syn. n., P. affinis medimontanus, syn. n., P. harzi, syn. n.) and P. hoelzeli (= P. kisi, syn. n.). The synonymy of P. poecilus with P. affinis and the subspecific status of P. affinis komareki are confirmed. One species, Poecilimon jablanicensis, sp. n., is described as new to science. A tabulated key, lists and maps of all known localities and oscillograms of the songs of all the species in this group are presented. The phylogenetic relationships and evolutionary trends in the Poecilimon ornatus group are discussed.
Ruavermis mikebargeri gen. et sp. n. infects the yellow-headed temple turtles Heosemys annandalii (Boulenger et Robinson) in the Mekong River Basin. It resembles Platt Roberts et Bullard, 2018 and Coeuritrema Mehra, 1933 by having the anterior to posterior anatomical sequence of a ventral sucker, external seminal vesicle, cirrus sac, anterior testis, ovary, transverse vitelline duct, and posterior testis. These genera are further similar by having the combination of an elongate/ovoid aspinous body, a ventral sucker at the level of the body constriction, an oesophagus that terminates in the anterior 1/5 of the body and that is ventral to the anterior nerve commissure, intestinal caeca that bifurcate in the anterior 1/3 of the body (not immediately anterior to the ventral sucker), a sinistral caecum that bends toward the midline at level of the cirrus and common genital pore, an external seminal vesicle that abuts the anterodextral margin of the cirrus sac, an oviduct that emerges from the dextral margin of the ovary, and an oviducal seminal receptacle that comprises the middle portion of the oviduct. These genera lack lateral oesophageal diverticulae and a median oesophageal diverticulum. The new genus is unique by having a papillate ventral body surface, an external seminal vesicle lateral to the cirrus sac, vasa efferentia that are ventral to the gonads, an oviduct that is convoluted, a Laurer's canal pore that is preovarian, a Laurer's canal that extends anterolaterad, and an excretory vesicle that is Y-shaped. The 28S rDNA phylogenetic analysis recovered the new species sister to Coeuritrema platti Roberts et Bullard, 2016, with that clade sister to Hapalorhynchus spp. and Platt spp. The new turtle blood fluke is the fourth from Vietnam, second from a Vietnam geomydid, and first from Heosemys Stejneger as well as the first endohelminth from the yellow-headed temple turtle., Haley R. Dutton and Stephen A. Bullard., and Obsahuje bibliografii
Long-eared bats of the genus Plecotus are widespread over most of temperate Eurasia, marginally reaching the African continent and Macaronesia. Previously, all African populations were assigned to one species, P. auritus, and later to P. austriacus. We analysed museum specimens of African long-eared bat populations using both morphologic and genetic techniques. Based on morphological evidence we recognise four well-defined allopatric populations in northern Africa. They differ in fur coloration, skull morphology and bacular traits. The molecular data support a division of the African populations into at least three well-separated evolutionary lineages. With a combination of these data we define three species of Plecotus occurring in Africa (incl. the Canary Islands) and describe a new subspecies. Small, very pale greyish-brown Egyptian long-eared bats (P. christii Gray, 1838) inhabit desert and semi-deserts habitats of eastern Sahara (Libyan Desert, Nile Valley of Egypt and northern Sudan). Smaller to medium-sized, dark brown Ethiopian long-eared bats (P. balensis Kruskop et Lavrenchenko, 2000) inhabit the Ethiopian Highlands above 2000 metres a. s. l. This form represents the only Afro-tropical species of Plecotus. Large, dark greyish Canarian long-eared bats (P. teneriffae teneriffae Barret-Hamilton, 1907) occur on the three western islands of the Canarian Archipelago. A medium-sized greyish-brown Gaisler’s long-eared bat, P. teneriffae gaisleri subsp. n., is described from the Mediterranean region of Cyrenaica, north-eastern Libya. Due to the lack of substantial morphological differences we preliminarily consider the Maghrebian population of long-eared bats to be consubspecific with P. teneriffae gaisleri subsp. n. The systematic position of the population of Cape Verde Islands remains uncertain.
Holotype and paratype of Ascocotyle (Phagicola) rara Arruda, Muniz-Pereira et Pinto, 2002, a heterophyid trematode recently described on the basis of two worms collected by Lauro Travassos in 1921 in the intestine of Ixobrychus exilis (Gmelin) from Brazil, were studied. The morphology of the worms revealed their conspecificity with Ascocotyle (Phagicola) angeloi Travassos, 1928 found in the same host. Both the taxa have a similar length (between 600 and 900 µm) and shape of the body (long pyriform), the long intestinal caeca reaching to the ovarian level, a long posterior muscular prolongation of the oral sucker and the prepharynx, transverse uterine loops situated between the ventral sucker and testes, and the gonotyl with more than 20 digitiform pockets. Consequently, A. (P.) rara is proposed as a junior synonym of Ascocotyle (Phagicola) angeloi.
The Capsalidae are monogeneans parasitizing ''skin'', fins and gills of marine fishes. Some capsalids are pathogenic to cultivated fish and a few have caused epizootic events. It is a cosmopolitan family with broad host associations (elasmobranchs and teleosts, including sturgeons). Approximately 200 capsalid species are placed in nine subfamilies and 44-46 genera, some of which are well known (Benedenia, Capsala, Entobdella, Neobenedenia). Sturgeons host two capsalid species (Nitzschiinae) and 15 species in five genera are reliably reported from elasmobranchs. The combination of ancient (shark, ray, sturgeon) and modern (teleost) host fish lineages indicates that capsalid evolution is likely a blend of coevolution and host-switching, but a family phylogeny has been lacking due to deficient knowledge about homologies. The current phenetic subfamilial classification is discussed in detail using a preliminary phylogeny generated from large subunit ribosomal DNA sequence data from representatives of five subfamilies. Monophyly of the Capsalidae is supported by possession of accessory sclerites. Hypotheses are proposed for the possible radiation of capsalids. A suggestion that Neobenedenia melleni, a pathogenic species atypical due to its broad host-specificity (>100 host teleost species from >30 families in five orders), may be a complex of species is supported from genetic evidence. This may explain peculiarities in biology, taxonomy, host associations and geographic distribution of N. 'melleni' and has implications for fish health. Holistic studies using live and preserved larval and adult capsalid specimens and material for genetic analysis are emphasised to further determine identity, phylogeny and details of biology, especially for pathogenic species.
Two new species of feather mites are described from nightjars (Caprimulgiformes: Caprimulgidae) of Brazil: Hartingiella neotropica sp. n. (Xolalgidae) described from Hydropsalis parvula (Gould) and Paragabucinia brasiliensis sp. n. (Gabuciniidae) from H. albicollis (Gmelin). The former differs from the type species by having, in males, the anterior projections on epimerites III towards setae 3b and the adanal shield bearing setae ps3 present; in both sexes, a pair of small sclerites situated posterior to setae se have flat suprategumental processes. Paragabucinia brasiliensis sp. n. differs from P. petitoti (Gaud et Mouchet, 1959) by the smaller size of the incisions in the internal margins of opisthosomal lobes of males. These mites are the first representatives of corresponding genera described from the Neotropical region. The genus Hartingiella Gaud, 1980 was previously known solely from its type species. Keys to males and females of the genus Paragabucinia Gaud et Atyeo, 1975 are presented. In addition, all previous records of feather mites associated with birds of the order Caprimulgiformes of the world are summarised.
