Habitat and material. By the courtesy and at the request of Prof. Vladimir Ebathof of Archangel I have been enabled to examine and describe two female copepods belonging to a new genus and species of the family Lernaeopodidae, consigned to him as taken from the gills of Rhyncodon typicus Smith caught in 1913 in the Pacific between China and south-west Japan. One specimen, drawn to scale (Fig. 1), was twice the size of the other.

Calcareous Ring

Paulayellus gustavi, a new sclerodactylid genus and species, is described from the Pacific coast of Panama. The new genus and species is assigned to the subfamily Sclerothyoninae based on a suite of characters, which include the radial and interradial plates of the calcareous ring united at the base only. Paulayellus gen. nov. differs from the other Sclerothyoninae genera in having posterior processesof radial plates undivided. Additionally, differs from Sclerothyone, Thandarum and Neopentamera in having knobbed buttons, plates and cups in the body wall (whereas the body wall is furnished only with tables and plates in Sclerothyone, Temparena and Thandarum, and only with knobbed buttons and plates in Neopentamera). The new genus is, so far, monotypic. The also monotypic genus Neopentamera proved to have the radial and the interradial plates of the calcareous ring united at the base only, as typically found in the Sclerothyoninae, and is therefore transferred to that subfamily. The discovery of a new genus in the Sclerothyoninae and the transfer of Neopentamera required the amendation of the diagnosis for the subfamily. A key to the Sclerothyoninae is given.

Pathogenicity Testing

Deniquelata barringtoniae gen. et sp. nov. (Montagnulaceae) forms numerous ascomata on distinct zonate leaf spots of Barringtonia asiatica (Lecythidaceae). We isolated this taxon and sequenced the 18S and 28S nrDNA. The result of phylogenetic analysis based on 18S and 28S nrDNA sequence data indicate that the genus belongs in the family Montagnulaceae, Dothideomycetes, Ascomycota. The ascomata are immersed, dark brown to black, with bitunicate asci and brown, muriform ascospores. Deniquelata is distinguished from the other genera in Montagnulaceae based on its short, broad, furcate and pedicellate asci, verruculose ascospores with short narrow pseudoparaphyses with parasitic naturee and this is also supported by molecular data. A new genus and species is therefore introduced to accommodate this taxon. We used isolates of this species to show via pathogenicity testing that the taxon is able to cause leaf spots when leaves are pin pricked.

A new genus and species, Richerius marqueti gen. et sp. nov., of a crab of the family Hymenosomatidae MacLeay, 1838 are described from the inland waters of New Caledonia based on several specimens collected in two streams at altitudes of 180 m and 500 m, respectively. Richerius marqueti gen. et sp. nov. was compared to the other freshwater species known in New Caledonia, Odiomaris pilosus (A. Milne-Edwards, 1873), and to species of Amarinus Lucas, 1980, a genus comprising many freshwater species in New Zealand, Australia, Indonesia, the Philippines, and Papua New Guinea, but never recorded in New Caledonia. The barcode fragment of the COI mitochondrial gene was sequenced for seven specimens of R. marqueti gen. et sp. nov., and all sequences were deposited in GenBank. A brief and updated review of the New Caledonian marine and freshwater hymenosmatid fauna is provided.

Tlacuatzoxyuris simpsoni n. gen. n. sp. is described from the cecum of the gray opossum, Tlacuatzin canescens, a species endemic to the deciduous dry forest of Mexico. The digestive tracts of four specimens were examined for parasites; three of these were archived in the American Museum of Natural History and one was a live capture. Relative to the other four monotypic genera of pinworms known to infect opossums, the new genus is diagnosed on the basis of a round cephalic plate with a semicircular stoma surrounded by a rim. In addition, males feature a prominent cephalic vesicle not fully developed in females, accounting for sexual dimorphism. The new species includes small worms that feature a conspicuous, not reticulated cephalic vesicle and semicircular stoma and lateral alae with two crests. In addition, the postcloacal cuticle of males features a small area with ornamentation between cloaca and submedial papillae. Finally, both spicule and gubernaculum are relatively short. Although the eggs of Tlacuatzoxyuris n. gen. are unknown, the conspicuous differences in traits used in the diagnosis of genera prompted us to propose a new genus for the new species. This is the first species of Oxyuridae reported in mouse opossums outside South America, and the fifth species of the family occurring in didelphimorph marsupials. This is an example of the usefulness of documenting the diversity of parasites associated with this unique clade of mammals through the examination of preserved tissues.

Mazon Creek

The family Syntonopteridae was named by Handlirsch in 1911 for a new genus and species, Syntonoptera schucherti, from the Upper Carboniferous of Mazon Creek, Illinois. Although the unique specimen on which the species was based consisted of only a wing fragment, the presence of several intercalary, triad veins was of unusual interest. During the 75 years that have passed since then, only six additional specimens of the family have been found (Carpenter, 1938, 1944; Richardson, 1956), all of them in the Mazon Creek beds. The latest of these specimens was sent to me for study by Dr. E. S. Richardson, Jr., a few months before his death, and I have only recently had the opportunity to study it and prepare illustrations. While working on this fossil, I decided to reexamine at the same time the other five specimens in the family known to me. A review of these specimens is included here, followed by revised diagnoses of the family and of the two known genera.

A new genus and species of Euryrhynchidae is described from Kerala, India. This freshwater shrimp family was previously only known from northern South America and West Africa. Although the inclusion of the genus in Euryrhynchidae is unequivocal (e.g. shape of the accessory ramus of the antennular flagellum, frontal margin of the carapace, telson ornamentation), the presence of a number of unique characters makes the relative placement of the genus within the family unclear, but likely basal to the other genera. The new genus can be easily distinguished from all others within the family by these characters, e.g. the upper antennular flagellum and its accessory ramus being joined over three divisions, the presence of a reduced carpo-propodal brush and a well-developed branchiostegal groove.

Phylogenetic Affinities

Cercosaurine lizards (subfamily Cercosaurinae of the family Gymnophthalmidae) represent a substantial component of the reptile fauna in the Neotropics. Several attempts have been made to reconstruct the phylogenetic relationships within this group, but most studies focused on particular genera or regions and did not cover the subfamily as a whole. In this study, material from the montane forests of Peru was newly sequenced. In combination with all cercosaurine sequences available on GenBank, an updated phylogeny of Cercosaurinae is provided. Monophyly was not supported for three of the currently recognised genera (Echinosaura, Oreosaurus, and Proctoporus). The genus Proctoporus is formed by five monophyletic groups, which should be used in future taxonomic revisions as feasible entities. Recognition of two previously identified undescribed clades (Unnamed clades 2 and 3) was supported and yet another undescribed clade (termed here Unnamed clade 4), which deserves recognition as an independent genus, was identified herein. Selvasaurabrava, a new genus and new species of arboreal gymnophthalmid lizard is described from the montane forests of the Pui Pui Protected Forest, Provincia de Chanchamayo, Región Junín, Peru. The new species is characterised by its small size (SVL 42.1–45.9 mm), slender body, smooth head shields, presence of paired prefrontal shields, fused anteriormost supraocular and anteriormost superciliary shields, transparent not divided lower palpebral disc, slightly rugose subimbricate rectangular dorsal scales in adults (slightly keeled in juveniles), distinctly smaller but non-granular lateral scales, smooth squared to rectangular ventral scales, and hemipenial lobes large, distinct from the hemipenial body. Phylogenetic affinities of the new genus to the other cercosaurine genera, as well as basal phylogenetic relationships between the other cercosaurine genera remain unresolved.

Cruciglanis pacifici, gen. et sp. nov., is described from the Dagua and Anchicaya Rivers on the Pacific slope of Colombia. The new genus is differentiated from the other genera in the family by the presence of an ossified crucifix-shaped second basibranchial; ectopterygoid bone shaped as an inverted comma, with its distal end narrow and directed medially towards the mesopterygoid; anterior fontanel elongated, reaching a transverse line at sensory canal opening of the sphenotic bone; caudal fin emarginated with rounded edges and ventral lobe more developed than the dorsal lobe; caudal fin with a dark spot from its base and fused with the peduncular spot, covering the anterior three quarters of its length, distal rim totally hyaline. Coloration of the species is described in vivo, and the shared diagnostic characters with the other genera within the Pseudopimelodidae are discussed. The phylogenetic position of the new genus is proposed and new insights in the family interrelationships are presented.

A new genus of terrestrial isopod (Oniscidea) belonging to the family Trichoniscidae, subfamily Haplophthalminae, Baeticoniscus n. gen., is described. We discuss its affinities and differences with the other genera of the same subfamily, which are characterized by presenting a completely smooth third pleonite. Baeticoniscus bullonorum n. sp. is described and designated as a type species of the new genus. The specimens of this new isopod come from the Cueva de la Pileta of Benaoján in the province of Málaga (Andalusia, Spain).

A new genus and species of Cyphophthalmi, Canga renatae gen. nov., sp. nov., is described in the family Neogoveidae from a system of caves in the Serra de Carajás, Pará State, Brazil. Canga can be easily distinguished from other neogoveid genera by the presence of a dentate claw on leg I, a unique character among known cyphophthalmid species, and by the free coxa II, which is fused to coxae III and IV in all the other neogoveid species except for the North American Metasiro. The new genus also differs from other Neotropical neogoveids in the lack of a dorsal crest on the chelicerae and in the lack of opisthosomal glands. The finding of a neogoveid in the Pará State greatly increases the known distribution of South American cyphophtalmids into the Eastern Brazilian Amazon forest.
