Eight new taxa of Eriophyidae mites associated with native trees in the Cupania genus—C. oblongifolia Mart. and C. impressinervia Acev (Sapindaceae)—from the Atlantic Forest in Brazil, are described and illustrated. They include two new genera and two new species of Nothopodinae, Colopodacini (Setibia domatiagena   gen. nov., sp. nov. and Aricolopodos alagoensis gen. nov., sp. nov.), one new genus and two new species of Cecidophyinae, Colomerini (Euryslobos keronidos gen. nov., sp. nov. and Gammaphytoptus cupanius sp. nov.), and one new species of Phyllocoptinae, Tegonotini (Shevtchenkella caboata sp. nov.).

Stalked Crinoids

Two new species of deep-sea stalked crinoids belonging to the family Hyocrinidae were collected in the northeastern Pacific. The descriptions contain detailed information on character variations and ontogeny. The five specimens of Gephyrocrinus messingi n. sp. lived at depths ranging from 1,777 m to 2,110 m off British Columbia and California. This new species is the first record of the genus Gephyrocrinus in the Pacific Ocean, which was previously known from only a single species, G. grimaldii, from the northeastern Atlantic at the same depth range. The two species illustrate opposing phenotypes within the same genus. Fifty-eight specimens of the second new species, Ptilocrinus clarki n. sp., were dredged off British Columbia close to the type-locality of P. pinnatus, the type species of the genus Ptilocrinus, but at shallower depths ranging from 1,178 to 1,986 m. This exceptional collection provides significant data on intraspecific variation in the main morphological characters, especially arm pattern. The ontogeny of stalk articulations and the main traits of adoral plate differentiation are described in detail. A complementary investigation on P. pinnatus was conducted using specimens collected by the “Albatross” expedition at a depth of 2,906 m. Despite similarities in external morphology, tegmen and cover plates, the two ptilocrinid species display significant differences in pinnule architecture, aboral cup and stalk articulations. From comparison with Gephyrocrinus messingi n. sp. and Ptilocrinus clarki n. sp., G. grimaldii and P. pinnatus are interpreted as the result of heterochronic development by paedomorphy after ecological or geographic isolation. Pinnule architecture in the two new species suggests first steps in an evolutionary trend toward a rigid box which protects gonad inflation in the proximal part of the pinnule. These new data on Ptilocrinus and Gephyrocrinus create problems in the current taxonomy of the family Hyocrinidae. The main derived characters, especially in pinnule and arm pattern, are used to propose new hypotheses for hyocrinid phylogeny.

The paramunnid genera Austrosignum Hodgson, 1910 (type species A. glaciale Hodgson, 1910) and Munnogonium George & Strömberg, 1968 (type species M. waldronense George & Strömberg, 1968) are re-diagnosed. Twenty seven species are reviewed. Austrosignum is restricted to two described species, Munnogonium to five described species. The remaining 20 species are placed in the following eight new genera: Boreosignum (type species Austrosignum maltinii Schiecke & Fresi, 1972), Cryosignum (type species Paramunna lunata Hale, 1937), Meridiosignum (type species M. macquariensis sp. nov.), Tethygonium (type species T. quadricuspis sp. nov.), Quetzogonium (type species Austrosignum dentatum Winkler, 1994), Advenogonium (type species Austrosignum fuegiae Doti & Roccatagliata, 2005), Zizzygonium (type species Paramunna magellanensis Winkler, 1994), Kussakinella (type species Austrosignum spinosum Kussakin, 1982).

Since the phylogenetic analysis of the Herrichella clade (Ochlerini) new genera were described to fit monophyletic groups inferred and considered to be new taxa. The clade I supported by two synapomorphies of the female genitalia, grouped Alitocoris brunneus Sailer together to two new species. Alloeogyna gen. nov. is described here for this clade including the two new species Alloeogyna ampla sp. nov. and Alloeogyna poecila sp. nov. and a new combination is proposed for Alloeogyna brunnea comb. nov.. Also, Alitocoris maculosus Sailer recovered within the clade E in the Herrichella clade is here redescribed in the monotypic Sailerus gen. nov. resulting in the new combination Sailerus maculosus comb. nov..
