A New Species

The genus Galumnopsis (Galumnellidae) is recorded for the first time from Mexico with a new species described here, and Notogalumna (Galumnidae), represents a second record for the country, also with a new species; both from the tropical rainforest in Veracruz state. Notogalumna rickiglesiasi sp. nov. lives in the canopy, while Galumnopsis andydoreyae sp. nov. inhabits soil and litter of Guarea glabra and Astrocaryum mexicanum; most likely they are not only restricted to these plants but are distributed in this forest on a continuous stratum across canopy (Notogalumna) or soil (Galumnopsis). A key for the species of each genus is included.

Nausithoe aurea, a new species of scyphozoan Coronatae, is described from São Paulo State, Brazil. The solitary scyphistomae, with some zooxanthellae, strobilated producing planuloids and medusae; this represents an intermediate life cycle between that of metagenetic Nausithoidae and the submarine cave-dwelling, reduced medusa stage of Nausithoe planulophora (Werner, 1971). The periderm tube of the scyphistomae has 16 internal cusps in all whorls. The medusae present yellow pigment spots in most of their lappets. The early embryonic development is briefly described. Planuloid formation is hypothesized as explanation for polyp-stage philopatry.

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.

Abstract We describe Hedruris dratini n. sp. (Nematoda, Hedruridae) from Hydromedusa tectifera and Phrynops hilarii in Argentina based on morphological and molecular characters. Also, we provide information about its life cycle. The new species differs from other species of the genus by possessing the excretory pore, nerve ring and deirids at equal distance from the anterior end. Additionally, H. dratini n. sp. has mammilated eggs and males possess nine pairs of caudal papillae. The subadults and adults of H. dratini n. sp and H. orestiae were characterized by sequencing the small subunit ribosomal DNA (18S). We present for the first time a life cycle of a species of Hedruris that includes an amphipod as intermediate host and a reptile as definitive host. Furthermore, we analysed the host and geographic distribution of all Hedruris species. Although the genus has a cosmopolitan distribution and parasitizes a great host diversity, the majority of species have a Gondwanian distribution, with amphibians being the preferred hosts.

Anagrus lindberginae sp. n. (Hymenoptera: Mymaridae), an egg par- asitoid of the leafhopper Lindbergina aurovittata (Homoptera: Cicadellidae), is described from Italy. It is included in the atomus group of Anagrus Haliday and compared with the allied known taxa. The parasitoid’s life cycle is characterized by a long larval diapause from spring to fall, which allows for synchronization with its leafhop- per host; other biological traits of A. lindberginae on the evergreen plant Quercus ilex are discussed.

A New Species

A newly discovered species of Pliciloricus from the deep sea of the Angola Basin (Namibia, Atlantic) seems to have two types of postlarvae in its life cycle. Type I is a simplified but clearly identifiable postlarval stage, the other type II consists only of a thin layer of cuticle as the remnant of a postlarva. Both types contain adults that have moulted from them. The simplified type I postlarva has a fully developed lorica with an ornamentation identical to that of the adult, but other body regions are reduced with only a few structures left. The discovery of this clearly identifiable postlarva is important, because it supports the conclusion that Pliciloricus-species originally moults from postlarval stages as well as other taxa of Loricifera. Furthermore, it could be concluded that the simple cuticle layer surrounding most adults found during their metamorphosis is the remnant of a postlarval stage. The life cycle of the new species seems to include two phases. After to the bisexual is a unisexual phase, represented by a simplified parthenogenetic adult stage which lacks most parts of the adult morphology. The adults of P. diva sp. n. differ from other species in having among others (1) a mouth cone with four strong cuticular bars plus eight primary oral ridges; (2) leaf-like clavoscalids which are very broad basally and narrow distally, and have more than 22 transverse cross walls; (3) a strongly sclerotized double-organ consisting of four rami; (4) large spinoscalids of second row shorter than clavoscalids, (5) short type B spinoscalids of fourth row with claw-tips and with a double row of five teeth as well as distally with a double row of minute denticles; (6) an anterior margin of the lorica with bicuspid protrusions and specific crescent-shaped ornamentations; (7) a midventral plica with five bar-like transversal strengthened ridges. Distinguishing features of the Higgins-larva are (1) short clavoscalids with broad second segments; (3) a collar with seven flosculi located in small pits; posterolateral setae being short but strong and pod-like. The study also revealed new information about the double-organ of the adult and the buccal structures of the Higgins-larva.
