Two new species ofPseudopetigurus (Trilobita) from the Arenig — Llanvirn of South China

Two new species ofPseudopetigurus are described from northern Hunan Province, China.P. deprati n. sp. is abundant in the upper Zitai Formation (upper Arenig) of Shuanghong, Baiyun, Shimen County, andP. expansus n. sp. occurs throughout the Jiuxi Formation (Arenig — lower Llanvirn) of Panjiazui, Taoyuan County. These formations represent outer shelf facies from the Jiangnan Transitional Belt of the South China Plate, close to the southeast margin of the Yangtze Platform. BothP. deprati andP. expansus show similarities to Upper Ordovician species ofPseudopetigurus recorded from South China. Other species ofPseudopetigurus are known almost entirely from cranidia, but pygidia and librigenae are also described for both new species, and the first known hypostome assigned to the genus is described forP. expansus. These two species are ecologically important members of offshore trilobite faunas during the Arenig — Llanvirn and define the outer shelfPseudopetigurus Association of South China. Despite being a deep-water genus,Pseudopetigurus is biogeographically restricted to the western margin of the Gondwanan craton and neighbouring regions of Baltica.      

Phylogenetic systematics of Schacontia Dyar with descriptions of eight new species (Lepidoptera,?Crambidae)

The Neotropical genus Schacontia Dyar (1914) is reviewed and revised to include eleven species. Schacontia replica Dyar, 1914, syn. n. and Schacontia pfeifferi Amsel, 1956, syn. n. are synonymized with Schacontia chanesalis (Druce, 1899) and eight new species are described: Schacontia umbra,sp. n., Schacontia speciosa,sp. n., Schacontia themis, sp. n., Schacontia rasa, sp. n., Schacontia nyx,sp. n., Schacontia clotho, sp. n., Schacontia lachesis, sp. n., and Schacontia atropos, sp. n. Three species, Schacontia medalba, Schacontia chanesalis, and Schacontia ysticalis, are re-described. An analysis of 64 characters (56 binary, 8 multistate; 5 head, 13 thoracic, 13 abdominal, 25 male genitalic, and 8 female genitalic) scored for all Schacontia and three outgroup species (Eustixia pupula Hübner, 1823, Glaphyria sesquistrialis Hübner, 1823, and Hellula undalis (Fabricius, 1781)) retrieved 8 equally most parsimonious trees (L=102, CI=71, RI=84) of which the strict consensus is: [[[[medalba + umbra] + chanesalis] + speciosa] + [ysticalis + [rasa + themis + [atropos + lachesis + nyx + clotho]]]]. The relevance of male secondary sexual characters to the diagnosis of Schacontia species is discussed.     

Four new species of splanchnotrophid copepods (Poecilostomatoida) parasitic on doridacean nudibranchs (Gastropoda,Opistobranchia) from?Japan,?with proposition of one new genus

Four new species of splanchnotrophid copepods are described based on specimens collected from 5 species of doridacean nudibranchs from coastal waters of Japan. They belong to 3 genera, one of which, Majimun gen. n., is new. The parasites and their hosts are as follows: Ceratosomicola japonica sp. n. ex Hypselodoris festiva (A. Adams); Splanchnotrophus helianthus sp. n. ex Thecacera pennigera (Montagu); Splanchnotrophus imagawai sp. n. ex Trapania miltabrancha Gosliner & Fahey; and Majimun shirakawai gen. et sp. n. ex Roboastra luteolineata (Baba) and Roboastra gracilis (Bergh). Ceratosomicola japonica sp. n. is the fifth species of Ceratosomicola and is characterized by the shape and armature of the prosome in females. Both Splanchnotrophus helianthus sp. n. and Splanchnotrophus imagawai sp. n. are differentiated from 4 known congeners by the absence of posterolateral processes or lobes on the prosome in females, and the females of these 2 new species are separated from each other by the shape and armature of the genito-abdomen, the mandible, and the swimming legs. Majimun gen. n. is distinguished from other splanchnotrophid genera by the segmentation of the antennule as well as the combination of the following characters in females: 2 postgenital somites and the shape of the antenna, the mandible and the swimming legs.     

Three new species of the carnivorous snail genus Perrottetia Kobelt, 1905 from Thailand (Pulmonata,?Streptaxidae)

Three new species of the streptaxid snail genus Perrottetia are described from north and northeastern Thailand, Perrottetia aquilonaria sp. n., Perrottetia dermapyrrhosa sp. n. and Perrottetia phuphamanensis sp. n. Each species is endemic to a single or a few limestone mountain ranges. The species are characterized by the morphology of their genital organs, as well as by shell characters. Perrottetia aquilonaria sp. n. has a club shaped distal penis and large penial hooks are present and penial papillae cover almost the entire penial hook portion; adjacent areas possess low reticulated folds. Perrottetia dermapyrrhosa sp. n. has a long genital atrium and the penial sheath is about two-thirds of the penis length. Penial hooks are long, scattered and sunken into deep ovate hollows; vaginal hooks are present. Perrottetia phuphamanensis sp. n. has a rounded and protruded shell periphery. The aperture is subcircular, peristome is thick and the second parietal lamella is adjacent to the first parietal lamella; a basal lamella is the smaller than in the other Thai species.     

Two new species of the genus Hedyotis (Rubiaceae) from China

Two new species of the genus Hedyotis L. (Rubiaceae) from southern China, H. wangii and H. yazhouensis, are described and illustrated.     

A new species of Rhytidognathus (Carabidae,?Migadopini) from Argentina

The Migadopini are a small tribe of Carabidae with 47 species that occur in South America, Australia, and New Zealand, in the sub-Antarctic areas. In South America, most of the genera inhabit areas related to sub-Antartic Nothofagus forest except two monogeneric genera, the Ecuadorian genus Aquilex Moret and the Pampean genus Rhytidognathus Chaudoir. These two genera are geographically isolated from the remaining five South American genera. New material of Rhytidognathus from the northeast of Buenos Aires province and from Entre Ríos province permits establishing that the previous records of Rhytidognathus ovalis (Dejean) for Argentina were erroneous and that it belongs to a new species. Based on external morphological characters and from male and female genitalia we describe Rhytidognathus platensis as a new species. In this contribution we provide illustrations, keys, habitat characteristics and some biogeographic considerations on the distribution of Rhytidognathus.     

Two new species and one newly recorded species of Elaphropeza Macquart from Taiwan (Diptera, Empididae, Tachydromiinae)

Previously 11 Elaphropeza species were known from Taiwan. The following two species of the genus Elaphropeza are described: Elaphropeza flaviscutumsp. n. and Elaphropeza trimaculasp. n. One species, Elaphropeza plumata Yang, Merz & Grootaert, is newly recorded from Taiwan. A key to 14 known species of Elaphropeza from Taiwan is presented.

Three new species of the Oriental empoascine leafhopper genus Dayus Mahmood are described from China: D. bifurcatus sp. n., D. trifurcatus sp. n. and D. serratus sp. n. A key to distinguish all Chinese species of the genus is provided.     

Two new species of Campomanesia (Myrtaceae) from Espírito Santo and Bahia, Brazil

Campomanesia macrobracteolata andC. anemonea, apparently closely related species from Espírito Santo and Bahia, Brazil, are described as new and are illustrated. Comparisons are made with two other similar species.     

Two new species of Tornidae (Caenogastropoda,Rissooidea) from Espírito Santo,Brazil

Two new species of shallow water Tornidae are found in Espírito Santo state, Brazil, formally described herein. They belong to a complex group of tiny gastropods, in such the taxonomy is very confused. Cyclostremiscus mohicanussp. n. is characterized by three well-developed spiral, equidistant carinas, working as base of three series of tall, aligned periostracal rods. Episcinia itanhunasp. n. has as single sculpture a series of pustules in periphery, but the periostracum bears three series of peripheral fringes with irregular rods. The new species are compared with the allies, showing a close relation with Caribbean fauna, but possessing worthy differences. These similarities have raised misidentifications.     

A new species of Coccus (Hemiptera,Coccoidea,?Coccidae) from China

A new species of soft scale, Coccus multisetus Wang & Feng, sp. n. is described and illustrated from Yunnan, China. A key to adult females of all Coccusknown from China is provided.     

Two new species and five newly recorded species of the genus Udea Guenée from China (Lepidoptera,Crambidae)

A checklist of the 31 Chinese species of Udea is given, including the new species and new records. Udea curvata sp. n. and Udea albostriata sp. n. are described and illustrated.
