Abstract Opiliones are highly diverse in the Neotropics. Because of biological constraints, most harvestmen communities are associated with humid forests, exhibiting a high species diversity and endemism in these habitats. Drier formations, such as the Caatinga biome in northeastern Brazil, are less diverse and still considered under-sampled for the order. This study represents an effort to examine the aforementioned diversity by describing a new Gonyleptidae genus, Sertanejagen. nov., comprising two new species from Ceará state, Sertaneja bicuspidatasp. nov. and Sertaneja crassitibialissp. nov., and one new species from Rio Grande do Norte state, Sertaneja falcatasp. nov. A morphological cladistic analysis consisting of 20 terminals and 72 characters was performed to evaluate monophyly of the new genus and relate it to other Gonyleptidae. The analysis resulted in a single most parsimonious tree, corroborating Sertanejagen. nov. monophyly and relatedness to Gyndoides springmanni Soares & Soares, 1947, which in turn is the sister group to the DRMN clade. Taking into account the morphological traits and phylogenetic placement of Sertanejagen. nov., we chose to place the new genus in Pachylinae despite its polyphyletic status, given that the Sertanejagen. nov. clade is closely related to one of the Brazilian Pachylinae lineage. A resolution to the Pachylinae conundrum is needed to further explain the subfamily intricacies. Future research requires a larger scope, but currently, based on the new genus monophyly, support, and relatedness, we formally propose its creation and hope to shed light on the possible evolutionary scenarios for the subfamily.

The Cryptini Eknomia Santos et Aguiar gen. nov. is proposed, described, and cladistically compared with representativespecies of 40 outgroup genera from twelve cryptine subtribes. A total of 98 morphological characters were evaluated. Allanalyses, conducted in TNT under implied and equal weighting, clearly suggest that Eknomia is a monophyletic groupand can be treated as a distinct genus. Its likely sister group, however, varied among different analyses and could not beascertained. The relationships of the new genus are therefore unclear, and because of this it is not assigned to any of thecurrently recognized subtribes. Eknomia can be diagnosed mainly by the anterior transverse carina of propodeum entirelyabsent; propodeum more or less uniformly strigate; clypeus almost entirely flattened; ovipositor stout, with compressed,minutely serrate flange at apex of dorsal valve, subapically crossed by a subvertical line; first metasomal spiracle placedat tergite midlength or nearly so; and hind margin of metanotum with tooth-like projections. The species E. nigra Santoset Aguiar, sp. nov., E. rubra Santos et Aguiar, sp. nov. and E. propodeator Santos et Aguiar, sp. nov. are described and illustrated. The genus is recorded from Colombia to southern Brazil.

A New Species

Corotoca is a strictly Neotropical genus of termitophilous beetles associated with termites of genus Constrictotermes. A cladistic analysis based on 13 terminal taxa and 60 characters (57 morphological and three behavioral) was conducted. The exhaustive search with equally weighted characters resulted in two most parsimonious trees with 95 steps. Spirachtha is proposed to be the sister group of the monophyletic “subgroup Corotocae” (Corotoca + Cavifonexus gen. nov.), based on eleven synapomorhphies (ten exclusive and one homoplastic). The monophyly of Corotoca is supported here, including six species associated with Constrictotermes cyphergaster: (Corotoca hitchensi sp. nov + (C. melantho + C. pseudomelantho sp. nov.) + ((C. fontesi + (C. phylo + C. araujoi)). A new genus, Cavifronexus gen. nov., is proposed to two species associated with Constrictotermes cavifrons (Holmgren, 1910): Cavifronexus guyanae comb. nov., from Guyana and Brazil, previously described as Corotoca; and a new species, Cavifronexus papaveroi sp. nov., from Brazil. This work also includes descriptions, redescriptions, and illustrations for all species and genera. Keys for genera and species identification in “subgroup Corotocae” are also provided.

Inti gen. nov. (Hymenoptera: Eulophidae: Entedoninae), is described from Costa Rica and the Dominican Republic, and includes one new species, I. levis sp. nov. The new genus is characterized by four autapomorphies, and the possession of an additional 14 synapomorphies. Inti is compared to the Australian genus Horismenoides Girault with which it shares the most apomorphies, indicating a possible sister-group relationship. The relationship of Inti to the tribe Euderomphalini and to other groups in the subfamily is discussed briefly.

In this review of Australian phreodrilid oligochaetes, several descriptions are amended, some species are reclassified and additional distribution data are provided for most species. One new genus (Nesodrilus) and 11 new species (Phreodrilus diemenensis, Phreodrilus melaleucensis, Phreodrilus mitodes, Antarctodrilus acanthaseta, Antarctodrilus micros, Antarctodrilus horwitzi, Nesodrilus southwellensis, Insulodrilus parviseta, Insulodrilus unisetoides, Insulodrilus bifidus and Astacopsidrilus myothyros) are described from Australia. Insulodrilus lacustris (Benham, 1903) is recorded in Australia for the first time, while Phreodrilus mauienensis Brinkhurst, 1971, and Astacopsidrilus campbellianus (Benham, 1909), comb. nov., are removed from the Australian species list. The latter is the first phreodrilid to be recorded on Macquarie Island. One new species, Insulodrilus novaezelandiae, is described from New Zealand and three new species, Antarctodrilus spinosus, Nesodrilus isochaeta and Astacopsidrilus beckettae, are described from Campbell Island. Aspects of phreodrilid zoogeography and anatomy are discussed.

The Mazon Creek Cycloidea contain four taxa: Cyclus americanus Packard, 1885, Cyclus obesus, new species, Halicyne max, new species, and Apionicon apioides, new genus, new species. We conclude, based on a cladistic analysis, that cycloids are specialized maxillopodan crustaceans and a possible sister group to the Copepoda. They may have filled a niche similar to modernday crabs.

Plate homologies are identified and discussed in primitive representatives of cornute and mitrate stylophorans. Comparative morphological analysis suggests that: 1) Lagynocystida are digital-bearing mitrates; 2) Peltocystida are glossal-bearing mitrates; 3) in Mitrocystitida, glossal and digital are incorporated into a closed marginal thecal frame or modified into articulated posterior spines (Anomalocystitidae); 4)Ovocarpus? circularisis synonymized withO. moncereti; 5)Chauvelia discoidalisandMitrocystites riadanensisare both assigned to the genusAspidocarpus; 6)Mitrocystella barrandeiis assigned to the new genusPromitrocystites.The original reconstruction ofVizcainocarpus dentigerproposed by Ruta, (1997a) is modified, as a result of the identification of two additional plates in the posterior portion of the theca. The new speciesVizcainocarpus rutaifrom the Tremadoc (Lower Ordovician) of Shropshire (England) is described and represents the oldest record of mitrocystitidan mitrates.V. rutaidiffers fromV. dentigerin the relatively broader size of its zygal and marginals and in the presence, on the lower thecal surface, of a peripheral fringe of fibrillar stereom. A cladistic analysis of selected stylophoran taxa based on the proposed plate homologies indicates that: 1) cornutes and mitrates are sister-groups, both deriving from aCeratocystis-like ancestor; 2) Peltocystida and Mitrocystitida are sister-groups; 3) Lagynocystida is sister-group of (Peltocystida + Mitrocystitida); 4)Lobocarpusis not a cornute but a primitive Cambrian mitrate belonging either to the stem-group of Mitrocystitida or to the stem-group of (Peltocystida + Mitrocystitida); 5) Anomalocystitidae represents a family of the suborder Mitrocystitida.
