Two New Species

Twenty-two new species and one new genus of euophryine jumping spiders from Central America and South America aredescribed. The new genus is Ecuadattus (E. elongatus sp. nov., E. napoensis sp. nov., E. pichincha sp. nov. and the typespecies E. typicus sp. nov.). The other new species belong to the genera Amphidraus (A. complexus sp. nov.), Belliena (B.ecuadorica sp. nov.), Chapoda (C. angusta sp. nov., C. fortuna sp. nov. and C. gitae sp. nov.), Ilargus (I. foliosus sp. nov.,I. galianoae sp. nov., I. macrocornis sp. nov., I. moronatigus sp. nov., I. pilleolus sp. nov. and I. serratus sp. nov.), Maeota(M. dorsalis sp. nov., M. flava sp. nov. and M. simoni sp. nov.), Soesilarishius (S. micaceus sp. nov. and S. ruizi sp. nov.)and Tylogonus (T. parvus sp. nov. and T. yanayacu sp. nov.). Diagnostic illustrations are provided for all new species. Photographs of living spiders are also provided for some new species.

Table Mountains

Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains – tepuis. Recently various international speleological expeditions to Churí-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churí-tepui and Auyán-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle larger than the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpi with a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.

External Morphology

The genus Gastrodynerus is here revised based on external morphology and male genitalia. Bohart (1984) proposed Gastrodynerus as a new genus with three species: G. vanduzeei (Bohart 1948), G. searsi Bohart, 1984, and G. stangei Bohart, 1984. Later, Rodriguez-Palafox (1996) added G. tacubayae (de Saussure, 1857). Herein, we describe four new species from Central America and South America: G. guatemalensis sp. nov.; G. barretti sp. nov.; G. aimara sp. nov. and G. yungaensis sp. nov. After this taxonomic revision, the Gastrodynerus includes eight species widely distributed in the New World. An identification key is provided for all of the species.

Morphological Differences

The tabanid tribe Diachlorini (Diptera) is the most genus-rich tribe in the Tabanidae; the tribe is cosmopolitan, but the greatest species richness and morphological diversity are found in the Australasian and Neotropical Regions. A new arrangement for the species of Acellomyia González is given; Acellomyia lauta (Hine) is transferred to a new genus, Montismyia gen.n., based on its morphological differences from Acellomyia and geographical distribution. The morphological differences between Acellomyia and Montismyia gen. n. are discussed. Two new species, Acellomyia casablanca sp.n. and Acellomyia puyehue sp.n., are described from specimens collected in southern Chile. Comparison of the morphology of Acellomyia paulseni mapuche (Coscarón & Philip) stat.nov. indicate that they should be elevated to species rank. A key to species of Acellomyia is provided and diagnostic characters are illustrated.

Two New Species

Cecidological and taxonomic investigations of members of the aphid tribe Nipponaphidini (Aphididae: Hormaphidinae) are proceeding very slowly owing to the rarity of galls and difficulty in distinguishing morphologies. We describe here two new Nipponaphidini species that induce galls on the primary host, Distylium racemosum Siebold & Zucc. (Isu tree, Hamamelidaceae), from Taiwan. One is designated Monzenia minuta sp. n. which induces a closed spherical gall on twigs of D. racemosum. The other one is designated as a new genus, Tripartita gen. n., and new species, formosana sp. n. which can induce open, spindle-like galls on leaves of D. racemosum and also on leaves of Distyliopsis dunnii (J.H.Hemsl.) Endress (Hamamelidaceae). This is the first report of the same hormaphidine aphid species inducing galls on two distinct primary hosts. Here we provide morphological diagnoses and cecidological information for both new species.

The new genus Neodrassex is proposed to include two new species of Gnaphosidae from Brazil. Neodrassex aureus sp. nov. is described from Amazonas, Paraná and Rio Grande do Sul states, and N. iguatemi sp. nov. is described from Paraná state. Neodrassex gen. nov. is characterized by small size, pale coloration, large anterior median eyes surrounded by black pigmentation, absence of a dorsal abdominal scutum in males and by the cheliceral dentition with 2-3 teeth on the promargin and 2-4 on the retromargin. The new genus is tentatively placed at the Leptodrassex group.

The Tanaidacea are ubiquitous and amongst the most abundant taxa in the deep sea. However, their diversity in submarine canyons remains largely unknown. Here, two new species and a new genus of Paratanaoidea are described. Paranarthrura cousteaui sp. nov. is distinguished by the combination of the following characters: post-cheliped sclerites not fused, presence of one seta in the maxilliped endite, one long midventral seta in cheliped, one penicillate seta in the basis of pereopods 4–6, uropod endopod bi-articulated and uropod exopod shorter than endopod article 1. This species was found at the upper reaches of three Portuguese canyons, Cascais, Setúbal and Nazaré Canyons, and the adjacent open slope, between 897 and 1001 m water depths. Tirana vallis gen. et sp. nov. presents a combination of the characters that define the other two genera of Paranarthrurellidae, Paranarthrurella and Armatognathia, but also unique characters within the family: the antenna, cheliped and uropod are more elongate than the rest of the species; the pereopods 4–6 carpus spines reach at least half of the length of the propodus and the propodus of pereopods 4–6 have ramified subdistal spines. This species was found at the middle reaches of Setúbal Canyon (3214–3219 m water depth).

This paper presents a new genus, two new species, and several new records of mites associated with insects and soil in Cuba. A new monotypic genus of Laelapidae, Acantholaelaps gen. nov., is described to accommodate a new species, A. strategus sp. nov., on the basis of adult female and male specimens collected on Strategus sarpedon (Burmeister) (Coleoptera: Scarabaeidae) and Strategus surinamensis hirtus Sternberg (Coleoptera: Scarabaeidae). The other species recorded were Macrocheles merdarius (Berlese) (Macrochelidae), Asca quinquesetosa Wharton (Ascidae), Gaeolaelaps cubaensis sp. nov. (Laelapidae) and Pseudoparasitus missouriensis (Ewing) (Laelapidae).

Anchialine Caves

Bahadzia, new genus, and two new species of amphipod crustaceans are described from anchialine caves in the Bahamas and Turks and Caicos Islands. One of the species is recorded from three caves on Grand Bahama Island and one cave on Great Abaco Island, whereas the other species is recorded from two caves on the island of Providenciales. The new genus is apparently more closely related to Metaniphargus and Saliweckelia than other hadziid genera in the peri-Caribbean region, but it also shares some important characters with Mayaweckelia.
