Nearctic Region

The taxonomy of the Nearctic Nylanderia fauna is revised. Three new species are established, bringing the total numberof native species from the region to 14. The new species are: N. magnella, N. querna, and N. trageri. Several speciespossess workers that are difficult to distinguish from each other and the presence of males is required for morphologicalidentification. This is particularly the case with N. vividula and N. terricola. Two subspecies are synonymized: N. vividulamjobergi is considered a junior synonym of N. vividula and N. vividula antillana is considered a junior synonym of N.guatemalensis. At least five Nylanderia species have been introduced to the Nearctic region, including: N. bourbonica,N. flavipes, N. fulva, N. pubens, and N. steinheili. Another species, N. guatemalensis, is also included because its widedistribution across the Caribbean and Central America suggest it could become introduced to the Nearctic region. Iden-tification keys are provided for the workers of native and introduced species and the males of native species. Distributionmaps are provided for native and introduced species. Photomontage images are provided for the worker of each introduced species and all castes of the native species.

Heth gordae n. sp., H. xarochae n. sp. and H. tuxtlensis n. sp. from the intestine of spiroboloids from Mexico are described herein. Females of H. gordae n. sp. and H. xarochae n. sp. can be differentiated from all other described species of Heth from the Americas by the presence of two sets of lateral spines with multiple cusps with a common broad base arranged in a semilunar shape pattern. Heth gordae n. sp. exhibits a narrower pattern that resembles more a comb-like structure, whereas H. xarochae n. sp. exhibits a broader pattern. Both aforementioned species resemble H. hexaspinosum from Panamá, but the latter possesses fewer spines without a common base. Lateral spines with multiple cusps have never been previously described in the genus Heth. Females of H. tuxtlensis n. sp. resemble Asian collar lappet-species but differ from them in possessing a complete uninterrupted collar with indented single lateral lappets. Specific characters described herein set these species apart from the Caribbean Heth species, most South American, and those previously described from Mexico. The present descriptions increase the number of Heth species recorded from Mexico from three to six.

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.

Three New Species

Species and genera of Bairdiidae can be difficult to discriminate, because of the somewhat limited morphological range of the carapace and limbs and the prevalence of homeomorphy. Attention to the esophageal flapper valve, an uncalcified but relatively well sclerotized structure, may contribute to more reliable identifications. Living species of Neonesidea exhibit sufficient variability in the architecture of this structure to suggest that it may have taxonomic value. Twelve named and three new species are examined to test this premise: N. bacata, N. caraionae n. sp., N. decipiens, N. credibilis n. sp., N. forea n. sp., N. edentulata, N. gerda, N. holdeni, N. longisetosa, N. manningi, N. mediterranea, N. omnivaga, N. plumulosa, N. schulzi, N. tenera. The geographic range of N. gerda is extended across the Gulf of Mexico, while the ranges of N. longisetosa and N. dinochelata are restricted. This supplemental information helps to clarify the relationships of several poorly known species from carbonate environments of Bermuda, the Bahamas, Florida, the Gulf of Mexico, and the Caribbean.

Three New Species

Background In Mexico, species of four families of free-living calanoid copepods have been recorded as inhabitants of several freshwater systems. These families are Centropagidae, Temoridae, Pseudodiaptomidae and Diaptomidae. The genera Leptodiaptomus and Mastigodiaptomus are the most speciose diaptomid genera in Mexico, and they inhabit natural and artificial lakes, ephemeral ponds, springs, and caverns. Leptodiaptomus is considered as an endemic Nearctic genus, whereas Mastigodiaptomus is a widely distributed Neotropical genus in the southern USA, Mexico, the Caribbean Islands and Central America. Based on new and recent evidence, Mastigodiaptomus diversity has been underestimated: six species of the genus were known before 2000. In this work three new Mastigodiaptomus species have been described from different regions of Mexico by using integrative taxonomy. We also gave amended diagnosis of M. nesus Bowman (1986) and M. patzcuarensis s. str. (Kiefer, 1938). Methods In this work, the taxonomic status of the species was clarified using modern, integrative method based on the COI gene as a DNA marker, plus micro-structural analysis (based on SEM and ligth microscopy). Results Three new species of Mastigodiaptomus were described based on genetic and morphological analyses: M. alexei sp. n., M. ha sp. n. and M. cihuatlan sp. n. Also amended description of M. nesus, morphological variation of M. patzcuarensis s. str., and a comparison of them with all known sequences within the genus are provided. These new findings show that in Mastigodiaptomus differences in several cuticular microstructures of several appendages (such as the antennules, the fifth legs, or the urosomites of these copepods) agree with the interspecific genetic divergence >3% observed in sequences of the COI gene, and the integration of this information is a powerful tool in species delineation.

Abstract: Seven species of terrestrial isopods are recorded from the coasts of the Pacific and Caribbean sides of Costa Rica. Three species (Buchnerillo neotropicalis, Hawaiioscia nicoyaensis and Trichorhina biocellata) are described as new and two species (Tylos niveus and Armadilloniscus cf. caraibicus) are newly recorded from the country. The poorly known species T. niveus is also illustrated. At present the total number of terrestrial isopod species recorded from Costa Rica is 30. Interestingly four typical littoral halophilic species (Ligia baudiniana, Tylos wegeneri, T. niveus and A. cf. caraibicus) are present on both the Pacific coast of Costa Rica and on the coasts of the lands encompassed by the Caribbean Sea. With the sole exception of A. cf. caraibicus, no morphological differences could be detected from the Pacific and Caribbean populations of those species. Rev. Biol. Trop. 66(Suppl. 1): S187-S210.

We revise the Cuban species of Eiphosoma Cresson (Hymenoptera: Ichneumonidae: Cremastinae). Three new species are described: E. bioeco sp. nov., E. dearmasi sp. nov. and E. nelitae sp. nov. All species are assigned to species-groups as defined by Gauld (2000) for the Mesoamerican fauna, and a key to Cuban species is provided. A preliminary analysis of the distribution and faunal similarity for species within the Cuban archipelago is discussed; the Cuban fauna is compared to that of the Caribbean Islands, Florida (USA) and Costa Rica.

The Sabellariidae has been scarcely studied in the Gulf of Mexico and the Caribbean Sea, and there are 18 species recorded out of 140 species known in the world. This work aims to improve the knowledge of the sabellariids in the northwestern tropical Atlantic region, provide standardized descriptions, and generate taxonomic identification keys. Sabellariids from three scientific collections were revised: Reference Collection of Laboratorio de Poliquetos, El Colegio de la Frontera Sur (ECOSUR), Chetumal, Collection of Laboratorio de Biodiversidad y Cambio Climático, ECOSUR, Campeche and Invertebrate Zoology Collection of Florida Natural History Museum, University of Florida, Gainesville. Three new species are described: Idanthyrsus bastidai n. sp. and I. mikeli n. sp. from Venezuela, and Sabellaria salazari n. sp. from the Yucatán Peninsula. In addition, new records of S. floridensis Hartman, 1944, S. vulgaris Verrill, 1873, and Phragmatopoma caudata Krøyer in Mörch, 1863 are provided.
