The records of nuculid bivalves from the Surma Group sediments of Mizoram, India, are very rare. This paper describes 3 known and 4 new forms of bivalves of the family nuculidae which were collected in the course of field study from Upper Bhuban Formation of Bhuban Subgroup (Surma Group), Mizoram. They are : Nucula alcocki Noetling, Nucula warsarensis Eames, Nucula cf. pulchara Hinds, Nucula agrawali n.sp., Nucula sahnii n.sp., Nucula tewarii n.sp., and Acila (Truncacila) kachharai n.sp. The first three forms, though, known from the other areas of the Indian subcontinent, are reported for the first time from the study area and their synonymy is updated.These forms, together with the other associated vivalves, gastropods and decapod crustacea, indicate a Lower Miocene (Aquitanian-Burdigalian) age and shallow marine enviroment of deposition for the Upper Bhuban Formation.

Bryophytes are the second largest group of land plants and are also known as the amphibians of the plant kingdom. 67 species of bryophytes have been reported from select locations across the state of Gujrat. The status of family fissidentaceae which is a large moss family is being presented in this paper. Globally the family consists of 10 genera but only one genus, Fissidens Hedw. has been collected from Gujarat. Fissidens is characterized by a unique leaf structure and shows the presence of three distinct lamina, the dorsal, the ventral and the vaginant lamina. A total of 8 species of Fissidens have been reported from the state based on vegetative characters as no sporophyte stages were collected earlier. Species reported from the neighboring states also showed the absence of sporophytes. The identification of different species was difficult due to substantial overlap in vegetative characters. Hence a detailed study on the diversity of members of Fissidentaceae in Gujarat was carried out between November 2013 and February 2015. In present study 8 distinct species of Fissidens have been collected from different parts of the state. Three species Fissidens splachnobryoides Broth., Fissidens zollingerii Mont. and Fissidens curvato-involutus Dixon. have been identified while the other five are still to be identified. Fissidens zollingerii Mont. and Fissidens xiphoides M. Fleisch., which have been reported as distinct species are actually synonyms according to TROPICOS database. The presence of sexual reproductive structures and sporophytes for several Fissidens species are also being reported for the first time from the state.

AbstractFrom the chronicles of the Family of Love we know that, besides printers in Deventer and later in Cologne, both Plantin and Augustijn van Hasselt printed for this religious sect. On the basis of this information quite a large number of publications have hitherto been attributed to Plantin, while only one single edition in Latin was reckoned to be the work of Augustijn. An analysis of the typography, however, shows that apart from Hendrik Niclaes's chief work, Den Spegel der Gherechticheyt, Plantin only printed two of his minor writings and that all the other ascriptions to Plantin must be revised in favour of Augustijn van Hasselt. In 1561-2 Augustijn was running a printing shop in the Dutch town of Kampen, specially set up by HN for the purpose of publishing those of his works that had not previously been printed. Plantin, who was partly involved in this enterprise, took the opportunity to have a book printed on this press for his publishing business. The analysis providing the typographical evidence of this collaboration proves for the first time the accuracy of the literary sources as regards Plantin's involvement in the publication of the works of Hendrik Niclaes. In the presentation of the new evidence it was necessary to establish more clearly the date of Plantin's '[1561]' inventory and which roman and German types he owned at what times. The article ends with some notes regarding the end of the 'Bohmbargen' press at Cologne.

A fossil of a mayfly nymph that shows similarities with the modern genus Teloganella Ulmer, 1939 of the family Teloganellidae is recorded for the first time from the Indian subcontinent. It is systematically described from the Gurha lignite mine of Bikaner, Rajasthan which belongs to the Palana Formation (late Paleocene-early Eocene). As assignment of the fossil to a modern species of Teloganella is difficult due to indistinguishable location of gills in the impression, a new species, Teloganella gurhaensis Agnihotri et al., sp. nov. is instituted to include this fossil naiad resembling the extant Teloganella.

Familial Hypophosphatemic Rickets (FHR) wasfound for the first time by Albright in 1937 andis also called vitamin D resistant rickets. 1-3 It isa disease that can occur through x-linked dominant,autosom dominant, and sporadic inheritance. 1-4Albright found that most FHR is x-linked dominanttype. 3 To distinguish between x-linked dominant andautosom dominant, the family pedigree can not beused, because it may look alike. Usually this diseasecan be distinguished genetically. The gene that isresponsible for x-linked dominant is located in Xp21while for autosom dominant is in 12p13. 4 Sporadictype can easily be distinguished from the other two.In the family pedigree, there is no other FHR patientbesides the patient himself. 3,4 The case that we areabout to report was a sporadic type FHR.

In this study, Bomolochus unicirrus Brian, 1902, a species of parasitic copepod belonging to the family Bomolochidae (Claus, 1875), was reported for the first time from the north-eastern Mediterranean waters off the Turkish coast. Parasites were collected from the gill filaments of the European barracuda, Sphyraena sphyraena(L.)captured by trawling in Iskenderun Bay, Turkey. The morphological features of B. unicirrus were Redescribed and illustrated based on the newly collected material. Key diagnostic characters and newly observed details in some structures are highlighted and supported by using scanning electron microscopy (SEM). Differences and simply overlooked details in previous descriptions of B. unicirrus, are discussed in detail. In addition, morphological comparisons between presently reported species and the other species of the genus Bomolochus Nordmann, 1832 were also presented.


Mites of the family Erythraeidae Robineau-Desvoidy, 1828 are distributed worldwide and have been reported as natural enemies of sucking pests. Adults and deutonymphs are predators; larvae of most species are ectoparasites of different arthropods. They can be harmful to beekeeping. Some species cause dermatitis in humans. Erythraeidae of the Caucasus are poorly studied. This article is the first report on mites of the genus Erythraeus Latreille, 1806 of the family Erythraeidae living in Azerbaijan. An annotated list of five species of mites of this genus collected in the Greater Caucasus is provided: Erythraeus phalangoides (De Geer, 1778), E. regalis (C.L.Koch, 1837), E. gorcensis Gabrys, 2016, E. opilionoides (C.L.Koch, 1837), E. adpendiculatus (Schrank, 1781). All of them are recorded from Azerbaijan for the first time. An identification key to imago of the Erythraeus species is given. The original photographs of imago were taken to clarify the determination. Mites were collected in three landscape zones: semi-desert (4 species), mountain-steppe (2 species) and mountain-forest (2 species). The Absheron Peninsula (semi-desert) is studied best; four Erythraeus species were found there. Most of the species were collected in artificial forests with a predominance of Eldar pine (4 species, 12 individuals). In other biotopes, mites of the genus Erythraeus are rare: 2 species (3 individuals) were found in broad-leaved forests of the low mountains, 1 species (1 individual) in a forb steppe, 1 species (1 individual) in an arid open woodland consisted of weeping pear trees, 1 species (1 individual) in a garden. Only four individuals of E. regalis were recorded on plants. The other mites were collected under stones, which will make it possible to attribute them to herpetobionts, and E. regalis to herpeto-hortobionts. Out of 18 individuals found, 17 were adult, and one larva of E. regalis was removed from spittlebug on a blackberry. The most common Erythraeidae genus in the Greater Caucasus is Abrolophus Berlese, 1891 (39 individuals belonging to eight species were collected). This is the only genus of the family Erythraeidae, found in four landscape zones, from semi-desert to subalpine. The genus Erythraeus was not found in the subalpine zone.

AbstractThe occurrence of trichodorids in a selected range of biotopes (fields and gardens, grassland, vineyards, orchards, forests, river banks and bushland) and their geographical distribution were studied throughout Slovakia. From a total of 684 soil samples collected, trichodorids were recovered from 225 (= 33%). Although members of the family Trichodoridae were present in more than 50% of the samples from forests and river bank vegetation, the prevalence of these nematodes in other biotopes was less than 20%. Six Trichodorus species (T. primitivus, T. similis, T. sparsus, T. variopapillatus, T. viruliferus and an undescribed species) and two Paratrichodorus species (P. macrostylus and P. pachydermus) were identified. T. sparsus was the most frequently occurring species (58% of all trichodorid records); the prevalence of the other seven species each accounted for less than 10% of the records. Individual trichodorid species showed an association with characteristic types of vegetation; e.g., T. sparsus was the dominant species in forest biotopes, T. similis preferred grassland, and T. variopapillatus wet soil associated with river bank vegetation. With the exception of T. sparsus and P. macrostylus, which occurred in various types of soil (sandy to loamy-clay), the other trichodorid species were found exclusively in lighter soils (sandy to loamy-sandy). T. variopapillatus is reported from the Slovak Republic for the first time and the records of P. macrostylus occurring in various biotopes in Slovakia extends the information on geographical distribution and ecology of this rare species. Vorkommen und Verbreitung von Trichodorus und Paratrichodorus spp. (Nematoda: Trichodoridae) in der Slowakischen Republik - Das Vorkommen von Trichodoriden in verschiedenen Biotoptypen (Acker und Garten, Grasland, Weinberge, Obstanlagen, Walder und Flussufer) und ihre geographische Verbreitung in der Slowakei wurden untersucht. In 225 (= 33%) von 684 untersuchten Bodenproben waren Trichodoriden nachweisbar. Wahrend in mehr als 50% der Proben aus Waldern und von Flussufern Arten der Familie Trichodoridae vorkamen, lag der Anteil 'positiver' Proben bei anderen Biotopen unter 20%. Sechs Trichodorus Arten (T. primitivus, T. similis, T. sparsus, T. variopapillatus, T. viruliferus und eine unbeschriebene Art) und zwei Paratrichodorus Arten (P. macrostylus, P. pachydermus) wurden nachgewiesen. T. sparsus wurde am haufigsten gefunden (58% aller TrichodoridenNachweise); der Anteil der ubrigen sieben Arten lag jeweils unter 10%. Einzelne Arten zeigten eine Bevorzugung bestimmter Vegetationstypen. So war T. sparsus die dominante Art in Waldbiotopen, T. similis bevorzugte Grasland und T. variopapillatus nasse Boden unter Flussufervegetation. Mit Ausnahme von T. sparsus und P. macrostylus, die in verschiedenen Bodenarten (sandig bis lehmigtonig) auftraten, wurden die ubrigen Arten ausschliesslich in leichten, sandigen bis sandig-lehmigen Boden gefunden. T. variopapillatus wird erstmals fur die Slowakische Republik gemeldet. Die Feststellung von P. macrostylus in verschiedenen Biotopen in der Slowakei erweitert unsere Kenntnisse uber die geographische Verbreitung und Okologie dieser seltenen Art.

AbstractDecapod crustaceans from the Ottnangian (middle Burdigalian, Lower Miocene) of the Western and Central Paratethys remain poorly known. In this study, we review and re-describe mud shrimps (Jaxea kuemeli), ghost shrimps (Gourretiasp.,Calliax michelottii) and brachyuran crabs of the families Leucosiidae, Polybiidae and Portunidae. A dorsal carapace of the genusCalliaxis reported for the first time in the fossil record. Re-examination of the type material ofRandallia strouhali(Leucosiidae) andGeryon ottnangensis(Geryonidae) resulted in a transfer of these species intoPalaeomyra(Leucosiidae) andLiocarcinus(Polybiidae), respectively.Achelous vindobonensis, originally described as a chela of a portunid crab, probably belongs to a member of Polybiidae and is provisionally treated asLiocarcinussp. Only two species,J. kuemeliandC. michelottii, are also known from the Karpatian, the succeeding Paratethyan stage. In most cases, the decapod assemblages of the Ottnangian consist of rather shallow-water taxa whereas the assemblages of the Karpatian consist of deep-water taxa from the middle and outer shelf. The Central Paratethyan assemblages show similarities in genus composition to the Proto-Mediterranean and recent Indo-Pacific regions.Gourretiasp. represents the earliest occurrence of the respective genus in the fossil record. The Oligocene–Early Miocene appearance ofPalaeomyraandLiocarcinusin the circum-Mediterranean implies that sources of present-day diversity hotspots in the Indo-Pacific trace to the Western Tethys (as for other decapod genera), although coeval decapod assemblages in the Indo-Pacific remain poorly known.

Three previously described monospecific genera of ictidosaurians (Tritheledontidae) are recognized on the basis of their postcanine dentitions. The least specialized is Pachygenelus monus , Watson (1913), the complete dentition of which is described for the first time: five specimens are described and referred to this species. The postcanine teeth of Diarthrognathus broomi , Crompton (1958) are described for the first time; they are derivable from those of Pachygenelus though considerably more specialized. Tritheledon riconoi , Broom (1912), from which the family derives its name, consists of a single specimen containing upper post-canines only; these are not closely comparable with the uppers of the other two genera but bear a strong resemblance to the lower postcanines of Diarthrognathus . The family is closely implicated in the origin of mammals and the possibility of polyphyly in the origin of mammals is raised.

Investigation of Eriosomatidae in Belarus started in the 1900s. However, a regional checklist of Eriosomatidae aphids was not published till now. Based on material preserved in the collections of Belarusian State University and the Zoological Institute of the Russian Academy of Sciences, and data scattered across publications we have compiled the first comprehensive list of Eriosomatidae recorded from Belarus and briefly analysed it from the geographical and ecological points of views. The list includes 12 genera and 27 species. Pemphigus passeki Börner, 1952 has been recorded from Belarus for the first time. The registered diversity is less abundant than in the adjacent Poland. In the accordance with the global pattern of aphids host plant connections, a single species permanently inhabit woody plants (monoecious species), the other ones are dioecious and migrate from woody plants to woody (eight species) or herbaceous (12 species) plants. Four species is anholocyclic.
