Analyses of the nuclear DNA marker 28S confirm the distinctness of the recently erected stonefly genus Zwicknia Murányi 2014, which encompasses the species until recently referred to as 'Capnia bifrons.' Two new species are described and illustrated with line drawings: Z. westermanni Boumans & Murányi, sp. n. from Germany and France, and Z. komica Murányi & Boumans, sp. n. from the Komi Republi...

One of the additions is Psorophora cyanescens, a new country record for Guatemala. Its presence in Mexico and Central America is revi...

A new issid genus in the tribe Parahiraciini (Hemiptera: Fulgoromorpha: Issidae) is erected for Fortunia jianfenglingensis Chen, Zhang et Chang, 2014 (China: Hainan). Male of the species is described and illustrated for the first time. A key for the 15 genera of Parahiraciini is provided. Morphological peculiarity and phylogenetic position of the new genus and the distribution of the tribe Para...

Iolanthe Beddard, 1886a is shown to be a senior synonyn of Acanthaspidia Stebbing, 1893, the replacement name for the preoccupied Acanthoniscus Sars, 1879 (Isopoda: Asellota: Acanthaspidiidae). Ischnomesus kussakini nom. nov. is erected as a replacement name for Ischnomesus antarcticus (Kussakin, 1982), preoccupied in this combination (Isopoda: Asellota: Ischnomesidae).

Arpylorus antiquus, erected by Calandra (1964), was isolated from Upper Silurian sedimentary rocks from the Mechiguig-1 borehole in southern Tunisia, with other palynomorphs. The folded vesicle and the quadrangular form of the aperture breaks down into plate-like fragments, resembling the tabulation of dinoflagellates. The presence of these elements, have been used to interpret A. antiquus as a...

THE DESCRIPTION of new taxa in a "Handbook of Hawaiian Fishes" recently submitted for publi cation was considered inadvisable . Certain of these are grouped together here, i. e., three new species of Gobiidae (Quisquilias aureoviridis, Q. limbatosquamis, and Hazeus ttnisquamis), a new genus and species of Callionymidae (Pogonymtts pogognathus), and a new suborder of Perciformes (Schindlerioidei...

A new genus, Biura gen. nov., is erected within the subtribe Aolina Boulard, 2012, designating Haphsa bicolora Sanborn, 2009 as the type species. This new genus is distinguished from all other genera in Aolina by the light-colored body lacking prominent markings, non-infuscated wings, very small and short male operculum, thin and long uncal lobes, and distinctly prominent basal lobes of the pyg...

Two new genera of wolf spiders belonging to Pardosinae, Gulocosa gen. n. and Melecosa gen. n., are erected to accommodate Gulocosa eskovi sp. n. (♂ ♀, Khabarovsk Province, Russia) and Sibirocosa alpina Marusik, Azarkina & Koponen, 2004, respectively. A new combination was also established: Melecosa alpina (Marusik, Azarkina & Koponen, 2004) comb. n. (ex. Sibirocosa). Polytomous and dichotomous ...

The short-line match-cast joint method of pre-casting concrete segments has proved to be the most versatile and reliable way to building pre-cast segmental bridges. The essential feature of match casting is that successive segments are cast against adjoining segment in the correct relative orientation with each other starting from the first segment away from the pier. The segments are subsequen...
