A new genus, Thaicypris gen. nov., in the tribe Herpetocypridini Kaufmann, 1900 of the subfamily Herpetocypridinae Kaufmann, 1900 is established to accommodate a new species from Thailand. The present contribution deals with the description of a new genus and species, Thaicypris panhai gen. et sp. nov., which is mainly characterized by the distinctive and raised, inwardly displaced selvage at the postero-ventral part of the right valve (RV) that is not parallel to the valve margin, the absence of an anterior inner list on the RV, the prominent and elevated double inner list on the posterior part of the left valve, the small and three-segmented Rome organ on the first antenna (A1), the spatulated terminal segment of the maxillular (Mx1) palp, the slender caudal ramus (CR) with long and thin Sp seta, the presence of basal triangle on the CR attachment, and the pointed projection at the terminal segment base of the prehensile palps. The hemipenis of the new genus and species is outstanding, especially the medial lateral shield which has a long, beak-shaped protrusion on the distal part. The discovery of this Thai taxon is the first record of the tribe Herpetocypridini in Thailand and the second species of the tribe in Southeast Asia.

The new genus Thaicypridopsis gen. nov. described here belongs to the tribe Zonocypridini Higuti & Martens, 2012 in the subfamily Cypridopsinae Kaufmann, 1900. It is the first record of the Recent representatives within this tribe in Southeast Asia and Oriental regions. Thaicypridopsis gen. nov. has a number of remarkable characters that distinguish it from other genera in the subfamily: a submarginal row of distinctive tubercles on the postero-ventral part of the right valve in the interior view, a strong serrated claw G2 on the second antenna with an apical concavity, large bristles with hirsute endings and spatula-shaped apexes on all three maxillular endites and a bifurcate tip on the terminal claw of the second thoracopod. One new species, Thaicypridopsis longispinosa sp. nov., is described under this new genus in the present contribution. Apart from the above diagnostic characters, the new species also has long spines on the valve surface as its outstanding feature. The new taxon is morphologically compared with other related species and genera within and outside the subfamily Cypridopsinae. In addition, due to the new genus belonging to a group of genera with the left valve overlapping the right valve in the subfamily, a key to the genera within this group is given.

A new genus and species of Philopotamidae (Philopotaminae),Aymaradellaboliviana, is described from the Bolivian Andes of South America. The new genus differs from other Philopotaminae by the loss of 2A vein in the hind wing and, in the male genitalia, the synscleritous tergum and sternum of segment VIII, and the elongate sclerotized dorsal processes of segment VIII. The first record ofHydrobiosella(Philopotaminae) in the New World is also provided with a new species from the Andes of Ecuador,Hydrobiosellaandina. In addition, a new species of the Neotropical genusChimarrhodella(Chimarrinae),Chimarrhodellachoco, is described from the Choco-Andean region of Ecuador, andChimarrhodellaperuviana(Ross) is recorded from Ecuador for the first time. Lastly,Wormaldiaimbrialis(Philopotaminae), new species, is described, also from the Ecuadorian Choco.

AbstractA new genus and species, Sacculozetes filosus, is described from riparian grassland in the Soviet Far East, and a new species, Guatemalozetes danos, is described from shortgrass and alpine prairie in western North America, both on the basis of adults. The genus Guatemalozetes Mahunka is redefined; this is the first record of this genus from temperate North America. A close relationship is indicated between Sacculozetes and Lamellobates Hammer, Paralamellobates Bhaduri and Raychaudhuri, and Hypozetes Balogh. The uncertain family placement of Sacculozetes and Guatemalozetes within the Ceratozetoidea is discussed. Adults of both genera exhibit character states of the Mycobatidae, but until immatures are discovered, they are considered unplaced genera in the superfamily.

A new genus, Osmanthedon Kallies gen. nov., in the tribe Synanthedonini and a new species, Osmanthedon domaticola Agassiz & Kallies spec. nov., are described. This is the first record of a sesiid species associated with ant galls (domatia) found on whistling thorn Acacia, Vachellia drepanolobium (Harms ex Sjöstedt) P.J.H.Hurter (Fabaceae), in East Africa.

In this paper a new species Cretonanophyes zherikhini sp. nov. and a new genus and species Abrocar brachyorhinos gen. et sp. nov., all placed within the family Eccoptarthridae, are described and illustrated. They pertain to the Late Jurassic Yixian Formation of the western Liaoning province, China. This finding represents the first record of fossil eccoptarthrids from China.

A new genus and species, Unguitarsonemus paradoxus n. gen., n. sp. and a new species, Pseudotarsonemoides peruviensis n. sp. (Acari: Trombidiformes: Tarsonemidae), are described based on phoretic females collected on bark beetles Phloeotribus pilula and Ph. biguttatus, respectively, from Peru. A key to species of the genus Pseudotarsonemoides is provided.

Abstract A new genus and species of carneyellid edrioasteroid, Spiracarneyella florencei n. gen. n. sp., is described from the Upper Ordovician (Kaitian) Point Pleasant Formation of northern Kentucky and southern Ohio. Spiracarneyella n. gen. is characterized by having all five ambulacra curving clockwise around the theca, having small node-bearing interambulacral plates in the distal interambulacra, and having the periproct placement slightly offset to the right side of the CD interambulacrum. The oral area of carneyellids evolved by paedomorphosis of the oral plates covering the mouth. The straight ambulacra of Cryptogoleus and the spiraling ambulacra of Spiracarneyella n. gen. evolved by paedomorphosis and peramorphosis, respectively.

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

The genus Candobrasilopsis gen. nov. is here described, with C. rochai gen. nov. sp. nov. as type species, from the alluvial valley of the Upper Paraná River. The enigmatic Candonopsis brasiliensis Sars, 1901 is here redescribed and transferred to this new genus, the new combination being Candobrasilopsis brasiliensis (Sars, 1901). The new candonid genus belongs to the tribe Candonopsini, because of the absence of the proximal seta on the caudal ramus. It is closely related to Latinopsis Karanovic & Datry, 2009, because of the relatively short terminal segment of the mandibular palp (length less than 1.5 times the basal width, while this segment is longer than three times the basal width in Candonopsis) and the large and stout b-seta on the T1. However, it differs markedly from Latinopsis in the size and shape of the calcified inner lamellae of both valves and in the type of hemipenis. We also discuss the doubtful allocation of several other genera to the Candonopsini, raise Abcandonopsis Karanovic, 2004 to generic status and reassess the uncertain position of Candonopsis anisitsi Daday, 1905 within Latinopsis.
