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.

A New Species

During recent investigations on the terrestrial invertebrates of the tropical rainforest on Martinique Island (Pitons du Carbet), specimens of a new species of the terrestrial amphipod genus Cerrorchestia Lindeman, 1990, C. taboukeli sp. nov., were collected by means of different quantitative and non-quantitative methods (hand collection and Tullgren extraction) in the forest floor. The new species can be easily distinguished from the only other species of the genus, C. hyloraina Lindeman, 1990, by gnathopod 2 (carpus short, palm longer than wide), pereopod 4 dactylus with a denticulate patch, pereopod 5 basis ovate with a deep posterodistal lobe reaching the distal end of the ischium, pleopod 3 ramus with more than six articles. Cerrorchestia tabouleki sp. nov. is the first forest-hopper discovered in the Lesser Antilles, raising the question of island colonization by terrestrial amphipods. Ecological data and a key to terrestrial Talitridae of Central America and the Caribbean islands are provided.

Three new species of Moniligaster Perrier, 1872, namely M. bahli Narayanan & Julka, sp. nov., M. blakemorei Narayanan & Julka, sp. nov. and M. keralensis Narayanan & Julka, sp. nov. are described from materials collected from the Indian state of Kerala. Moniligaster cernosvitovi Gates, 1962, Moniligaster horsti Gates, 1940, Moniligaster michaelseni Gates, 1940 and Moniligaster stephensoni Gates, 1940 are recorded for the first time from the state. With the new findings, a total of 10 Moniligaster species are known from Kerala. Moniligaster species are restricted to southern peninsular India, except Moniligaster ivaniosi Manazhy, 2011, decribed from the Andaman Islands, outside the currently known distributional range of the genus. Hence we critically reviewed the original description and reinvestigated the holotype. As a result, Moniligaster ivaniosi is considered a junior synonym of Drawida nepalensis Michaelsen, 1907.

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.

Three New Species

A taxonomic revision of the pyramidellid genus Eulimella from Brazil was performed based on shell morphology. The holotype of Eulimella rudis Watson, 1886 is illustrated and compared to shells from the southeast Brazilian coast, this being the first confirmed record of this species after its original description. Eulimella smithii (Verrill, 1880), previously known from northern localities in the western Atlantic, is recorded from the southwestern Atlantic, along virtually the entire Brazilian coast; it is herein considered a distinct taxon from Eulimella unifasciata (Forbes, 1844), a very similar species from the eastern Atlantic, given the lack of data on development to consider an amphi-Atlantic distribution. Three new species are described: Eulimella torquata sp. nov., diagnosed by a constriction in the middle of each teleoconch whorl caused by a strong spiral furrow, producing a bilobed whorl profile; Eulimella cylindrata sp. nov., diagnosed by a large subcylindrical teleoconch; and Eulimella ejuncida sp. nov., characterized by its very slender shell, and small protoconch with only one whorl and with an “arc” shaped suture. The shells herein identified as Eulimella cf. calva from Brazil are conchologically identical to Eulimella calva Schander, 1994, from West Africa, but their taxonomic status should remain dubious because of lack of biological information to evaluate a possible amphi-Atlantic distribution pattern. All the species studied (except Eulimella ejuncida sp. nov.) have characteristic short microscopic axial threads organized in a spiral belt, varying in position and expression among species, but usually located in the middle of each teleoconch whorl or below the suture; this characteristic is also present in some species from the eastern Atlantic. Three South American species, originally or subsequently allocated in Eulimella, are herein considered as not belonging to this genus: Eulimella argentina Doello-Jurado, 1938; Eulimella bahiensis Castellanos, 1982; and Eulimella xenohyes (Melvill & Standen, 1912). The holotype of Eulimella lissa is illustrated with SEM micrographs.

First Time

Two species of Endoclita C. &. R. Felder, 1874 from Taiwan are evaluated for their taxonomic status: Endoclita meifenga Buchsbaum & Grehan sp. n. is described as new for a unique male from the central mountains of Taiwan, and E. kosemponis (Strand, 1916), stat. rev. is elevated to species status. We show that the forewing markings and genitalic characteristics of E. meifenga sp. n. distinguish this species from all other Endoclita. The external appearance of E. kosemponis is similar to E. sinensis (Moore, 1877) but the two species show distinct differences in the male and female genitalia. Preliminary comparison of E. sinensis from Taiwan and Japan suggests they represent more than one species. A sample of the COI gene was sequenced for E. meifenga sp. n. and the primary types of E. meifenga sp. n. and E. kosemponis sp. n. are illustrated here for the first time. The taxonomic status of the non endemic Taiwanese E. davidi (Poujade, 1886) and E. sinensis needs future evaluation.

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.
