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.

A new genus and species of scale insect (Hemiptera: Coccomorpha) is described from a female specimen in mid-Cretaceous Burmese (Myanmar) amber. Fossil female scales are rare and the present species, described as Paleolepidotus macrocolus gen. et sp. n., has such an unusual assortment of morphological features that it could not be assigned to any particular extant or extinct family. The small, ferruginous specimen exhibits a series of long wax pencils that extend around the body, including the head. The antennae and legs are quite long compared to other extant and extinct scale fossils. Of special interest are the protruding eyes, and a conical-triangular rostrum arising from between the forelegs; the claws with bifid apices are also unique. The ovisac contains immature stages.

General Appearance

Melaniphax suffusculus gen. et sp. nov. is described from Costa Rica, representing the 57th delphacid species recorded from the country to date. The new genus is superficially similar to Caenodelphax Fennah in general appearance in that the body is uniformly colored with the wings infuscated. Distinctive features of the new taxon include simple, forceps-like gonostyli, a broadly compressed aedeagus with large serrate lateral flanges, and the anal tube bearing a pair of short, stout, truncate, caudally-directed processes on the ventro-caudal margin and slender, elongate processes from the antero-ventral margin.

Oligodendrorhynchus hesperides gen. et sp. n. (Heteronemertea) from the Bellingshausen Sea A new genus and species of heteronemertean from the Antarctic (Bellingshausen Sea), Oligodendrorhynchus hesperides, is described and illustrated. Some morphological features with major systematic significance are following: the mode of branching of the proboscis and its low number of terminal branches; the lack of horizontal lateral cephalic slits but in their place a pair of shallow epidermal depressions; a gelatinous amorphous connective stratum between the outer longitudinal and circular muscle layers; the presence of a rhynchocoelic nerve; isolated fibres of the rhynchocoel circular muscle layer interwoven with bundles of the adjacent body-wall inner longitudinal muscle fibres in the intestinal region. Other anatomical characters which can also be used to distinguish the new taxon from existing heteronemertean species that have a branched proboscis are also discussed.

A new genus and species of laetmogonid holothurian (Elasipodida, Laetmogonidae), collected from around the Crozet Plateau in the Southern Indian Ocean, is described. It differs from other members of the family in that the body wall lacks the wheel-shaped calcareous deposits completely. Instead only rods are present. The genus is also distinguished by the combination of other morphological characters lacking in other known genera: absence of circum-oral and ventrolateral papillae together with development of midventral tube feet. All other members of the family Laetmogonidae are known to have wheel-shaped deposits, therefore diagnosis of the family is refined.

Introrsa, a new genus and species of the tribe Opsiini from southern China (Yunnan) is described. Diagnosis of the new genus together with information on the karyotype is given. Introrsa most closely resembles Opsius Fieber, but it is the first genus of the Opsiini with the body longer than 8 mm and can be distinguished from the latter by body not wedgeshaped, head as broad as pronotum and aedeagus with socle not bulbous. The sex determination system is XO/XX and the karyotype of the species is 2n=12(10+XO). The detailed morphology of the new genus is described; external habitus and line drawings of male and female gentalia of the new taxon are given. An annotated check-list and generic key to Old World members of the leafhopper tribe Opsiini are provided.

Flexorincus, new genus and species, is described from 15 specimens (14.0–27.2 mm SL) collected from shallow (0–9 meters) intertidal and sub-tidal waters of the Rangitāhua Kermadec Islands, New Zealand. The new taxon is distinguished from all other members of the Gobiesocidae by a combination of characters, including a heterodont dentition comprising both conical and distinct incisiviform teeth that are laterally compressed with a strongly recurved cusp, an oval-shaped opening between premaxillae, a double adhesive disc with a well-developed articulation between basipterygia and ventral postcleithra, and many reductions in the cephalic lateral line canal system. The new taxon is tentatively placed within the subfamily Diplocrepinae but shares a number of characteristics of the oral jaws and the adhesive disc skeleton with certain members of the Aspasminae and Diademichthyinae.

Abstract Stenamara mia is a new genus and species of a rare pycnodontiform fish from the Barremian, early Cretaceous, lacustrine beds of Las Hoyas, province of Cuenca, Spain. It was previously considered Eomesodon sp., but a number of characters clearly separates it from the genus Eomesodon: lack of prognathism; absence of nuchal plates; presence of a parietal process and of only two rows of teeth in the prearticular; and peltate pattern of ossification and distribution of scales, that is, scales are present only before the level of the unpaired fins, and are complete only in the ventralmost abdominal area. The unique combination of these and other characters, plus the following autopomorphies, diagnoses the new taxon: presence of a strongly curved dorsal prominence that results in an ovoid shape of the contour of the body; body deeper than long, with maximum body height near 125% of standard length; and narrow, high cloaca formed by only two differentiated scales, the posterior one considerably longer than the anterior one. Stenamara mia nov. gen. nov. sp. is considered a primitive Pycnodontidae, pending a cladistic analysis to determine precisely its phylogenetic relationships.

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.
