Exceptionally large quantities of outstandingly well-preserved, free specimens of larger foraminifera from late Miocene sediments of the Dominican Republic invite an analysis of their structure in detail. The structures of the porcelaneous larger foraminifera reveal that most of them are not candidates for a direct ancestry of the species living today in the Caribbean. Although the late Miocene period has produced Caribbean endemists, in particular within the agglutinated group of the textulariellids and the lamellar-perforate group of the amphisteginids, the porcelaneous archaiasines and soritines are more closely related to the early Miocene forms of the Neotethys than to the Recent Caribbean endemists. These relationships are derived from their relative structural similarity and call for the proposition of appropriate additional taxa on the generic and specific levels. Miocene Miarchaias new genus develops several centimeters large, cyclical agamonts with meandropsinid structures covering the lateral surface of the disc (M. meander new species) whereas species of smaller shell size do not have cyclical generations (M. modestus new species). On the other hand, populations of cyclical schizonts and/or gamonts exhibit structures similar to the Recent, spiral Androsina: Androsinopsis radians new genus and species. The other new taxa erected here, Annulosorites spiralis new genus and species and Cyclorbiculina miocaenica new species, reflect differences in the apertural face and the respective arrangement of radial partitions as used to differentiate Recent Sorites from Amphisorus. Specimens to be attributed to the genera Cycloputeolina and Parasorites are present in the late Miocene of the Dominican Republic. They exhibit an exoskeleton in contrast to true soritids, and will need an eventual worldwide revision on the species level.

Thirteen new species of sponges are described from coral reefs of the Netherlands Antilles and the Colombian Caribbean. Species were collected during quantitative investigations of reef sponges performed by students of the University of Amsterdam in the period between 1984 and 1991. Most of the reported specimens were taken from undersides of coral rubble, crevices or reef caves (sciophilous habitats) and without exception are small encrusting or fistular sponges. The material reported in this paper includes a new genus and species of Placospongiidae, Placospherastra antillensis n. g. n. sp. , the first Caribbean representatives of the genera Triptolemma (Pachastrellidae) and Megaciella (Acarnidae), viz. Triptolemma endolithicum n. sp. and Megaciella incrustans n. sp., a new species of Timeidae, Timea curacaoensis n. sp., a new species of Microcionidae with peculiar colloscleres, Clathria (Thalysias) collosclera n. sp., two new species of Chondropsidae, viz. Batzella fusca n. sp., and Strongylacidon unguiferum n. sp., three new species of Coelosphaeridae, viz. Forcepia (Forcepia) minima n. sp., Forcepia (Forcepia) fistulosa n. sp., and Forcepia (Leptolabis) microlabis n. sp., a new species of Crellidae, Crella (Grayella) beglingerae n. sp., a new species of Hymedesmiidae, Hymedesmia (Hymedesmia) bonairensis n. sp., and a new species of Mycalidae, Mycale (Paresperella) vitellina n. sp. Most species are represented by only small fragments removed from the substrate by scalpel or diving knife, leaving little and often crumbled preserved type material. This study is intended to demonstrate that the small crusts dominating easily accessible shallow water coral rubble habitats in the Caribbean remain understudied.

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.

Marine planarians were collected extensively from the Iberian Peninsula and Italy. As a result we provide new distributional records of six species of marine triclads, including the description of one new genus and species. The study increases substantially our knowledge of the distribution of this group of animals in Spain and reveals that even relatively well studied areas, such as Italy, still yield new species. In addition, we performed immunostaining studies of the nervous system of three of the species, which revealed the detailed organization of the main nerve cords and their branches. In the new species, the lateral nerve branches showed an arrangement that is different from that of the other species.

AbstractAnthobioides pubescens, an unusual new genus and new species of rove beetle, is described from the Olympic and Mt. Rainier National Parks, WA. The genus is assigned to the Anthobium-group of genera in the tribe Anthophagini, subfamily Omaliinae. The new genus represents the sister group of the genus Camioleum Lewis from Japan. The phylogeny of Anthobioides and Camioleum and their relationship to the other four genera assigned to the Anthobium-group is discussed. All pertinent characters of Anthobioides are illustrated by line drawings or scanning electron photomicrographs.

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.

A new riffle beetle, Zunielmis pax gen. et sp. nov., is described from Colombia (Vichada, Puerto Carreño, Bita River basin). It can be distinguished from all the other elmids by having large areas of a microgranular mesh (plastron) on the pronotum and elytra, crenulate lateral margin of the latter two, the shorter interocular distance than diameter of each eye, as well as by the characters of the structure of mandibles, the shape and sculpture of pronotum, and the structure of mesosternum, mesotibiae and elytra. The imagoes were collected on freshwater sponges. The habitat, where the new species was found, is described, and the adaptive meaning of the characteristics of plastron are discussed. Drawings and photographs of the adult habitus, distinctive morphological characters, and male and female genitalia are provided.

Abstract Enigmatic and rarely collected, ambush bugs of the tribe Macrocephalini (Heteroptera: Reduviidae: Phymatinae) encompass a diverse group of predatory bugs armed with subchelate raptorial forelegs, a greatly enlarged scutellum, and elongate head. Macrocephalini is the most specious of the four tribes of ambush bugs, consisting of 20 genera and 154 species. They are represented in the Caribbean by several remarkable taxa that bear foretarsi, a trait unassociated with macrocephalines found elsewhere in the world. I here describe a new genus and species of Macrocephalini, Capricephala chiaroscuro gen. et sp. nov., native to the island of Hispaniola and one that bears striking differences to other phymatines known from that region.

The first fossil Solenoceridae found from the Cretaceous (Aptian–Albian) is described in the Araripe Sedimentary basin, Priorhyncha feitosai n. gen. n. sp. The material was collected in the strata of the Romualdo Formation, municipality of Trindade, Pernambuco. Characters that permit placement of the new species in Solenoceridae are: a short, dorsally serrated rostrum; a marked cervical groove; and the presence of an antennal spine. Those characters are also diagnostic for Priorhyncha feitosai n. gen. n. sp. when compared to the other Dendrobranchiata shrimp described from this basin.

Diagnoses of all stages of the new genus Onconeura are given. The genus includes O. undecimata new species, from Chile, described as male, female, and pupa, and O. semifimbriata (Sæther) new combination from the Caribbean and Mexico. The genus belongs to the Corynoneura group of genera and appears to form the sister group of Corynoneura Winnertz, Tempisquitoneura Epler, Thienemanniella Kieffer, and perhaps Notocladius Harrison combined. The following combination of characters will separate the genus from the other members of the group: bare eyes; tergites without raised, median area of setae; all trochanters with dorsal keel; hind tibial apex not broadened; male transverse sternapodeme well developed with strong oral projections; female gonocoxite IX well developed but adpressed, with a few setae; coxosternapodeme with a few spine-like anterior projections; and apodeme lobe and labia large. The pupa differs by having 4–7 rows of pearls on the wing sheath, one weak non-taeniate macroseta, and tergal conjunctives with posterior rows of up to 10 strong recurved spines (hooklets). The larva differs from that of Corynoneura and Thienemanniella by having the antenna shorter than half the length of the head, but about one third the length, as opposed to one fourth in Tempisquitoneura.

A New Species

A new genus with a new species of soft-winged flower beetle, Pectotibialis paghmanensis Tshernyshev gen. et sp. nov. are described from Afghanistan. The new genus can be distinguished from the congeners of the tribe Apalochrini by the dark pectination in the apices of tibiae in both sexes, and the anterior tibiae which are hollowed at distal half, flattened and rounded femora, bituberculate basal parts of head and pronotum, two lamellate metathoracic appendages, tarsal comb above second tarsomere of anterior legs, and serrate antennae in the male. Based on the metathoracic appendages and comb in anterior legs would attribute this new species to the new genus Dromanthomorphus Pic, 1921, but all the other above-mentioned characters define its independent status and the designation of a new genus; Pectotibialis Tshernyshev gen. nov. The external appearance, special male characters and genitalia of the type species of the new genus are illustrated, and a distribution map is provided. A key to the Apalochrus-section of the tribe Apalochrini is provided.
