We describe Proceraea albocephala, new species, from Madeira, and Erseia oligochaeta, new genus and new species, from Istria, Croatia, and we provide redescriptions of Proceraea madeirensis (Nygren, 2004) from topotype material, and Myrianida longoprimicirrata (López, San Martín & Jimenéz, 1997) from material collected at Istria, Croatia, and Banyuls-sur-Mer, France. Proceraea albocephala, new species is morphologically separated from similar species by a prostomial white spot, and E. oligochaeta, new genus, new species is unique in having only a few (1–2) simple unidentate chaetae in all chaetigers, and a trepan with a single large and 25–28 smaller teeth. We assess the phylogenetic positions of the four species using nuclear 18SrDNA, together with mitochondrial COI and 16SrDNA. Our molecular data show that among the sequenced autolytines 1) P. albocephala, new species is most closely related to P. nigropunctata Nygren & Gidholm, 2001, P. okadai (Imajima, 1966), and P. cornuta (Agassiz, 1862), 2) E. oligochaeta, new genus, new species belongs within a clade together with Procerastea nematodes Langerhans, 1884, Virchowia clavata Langerhans, 1879, and Imajimaea draculai (San Martín & López, 2002), 3) M. longoprimicirrata is sister species to M. pentadentata (Imajima, 1966), and 4) P. madeirensis has a basal position within Procerini. The molecular data suggests that Proceraea Ehlers, 1864 as currently delineated is paraphyletic.

For 130 years the diogenid genusPaguropsisHenderson, 1888 was considered monotypic for an unusual species,P.typicaHenderson, 1888, described from the Philippines and seldom reported since. Although scantly studied, this species is known to live in striking symbiosis with a colonial sea anemone that the hermit can stretch back and forth like a blanket over its cephalic shield and part of cephalothoracic appendages, and thus the common name “blanket-crab”. During a study of paguroid collections obtained during recent French-sponsored biodiversity campaigns in the Indo-West Pacific, numerous specimens assignable toPaguropsiswere encountered. Analysis and comparison with types and other historical specimens deposited in various museums revealed the existence of five undescribed species. Discovery of these new species, together with the observation of anatomical characters previously undocumented or poorly described, including coloration, required a revision of the genusPaguropsis. The nameChlaenopagurusandersoniAlcock & McArdle, 1901, considered by Alcock (1905) a junior synonym ofP.typica, proved to be a valid species and is resurrected asP.andersoni(Alcock, 1899). In two of the new species, the shape of the gills, length/width of exopod of maxilliped 3, width and shape of sternite XI (of pereopods 3), and armature of the dactyls and fixed fingers of the chelate pereopods 4, were found to be characters so markedly different fromP.typicaand other species discovered that a new genus for them,Paguropsinagen. n., is justified. As result, the genusPaguropsisis found to contain five species:P.typica,P.andersoni,P.confusasp. n.,P.gigassp. n., andP.laciniasp. n.Herein,Paguropsinagen. n., is proposed and diagnosed for two new species,P.pistillatagen. et sp. n., andP.inermisgen. et sp. n.;Paguropsisis redefined,P.typicaand its previously believed junior synonym,P.andersoni, are redescribed. All species are illustrated, and color photographs provided. Also included are a summary of the biogeography of the two genera and all species; remarks on the significance of the unusual morphology; and remarks on knowledge of the symbiotic anemones used by the species. To complement the morphological descriptions and assist in future population and phylogenetic investigations, molecular data for mitochondrial COI barcode region and partial sequences of 12S and 16S rRNA are reported. A preliminary phylogenetic analysis using molecular data distinctly shows support for the separation of the species into two clades, one with all five species ofPaguropsis, and another with the two speciesPaguropsinagen. n.

Species Descriptions

Chondrocyclus Ancey, 1898 is a genus of nine species of African operculate land snails restricted to indigenous forest and mesic thicket. Worn specimens (i.e., without a periostracum or operculum), on which some species descriptions and records were based, appear to be indistinguishable morphologically. A comprehensive revision of Chondrocyclus s.l. is provided here based on comparative morphological examinations of the shell, protoconch, periostracum, operculum, radula and penis, and on mitochondrial genes cytochrome c oxidase subunit I and 16S rRNA. Two genus-level lineages are recognised, Chondrocyclus s.s. and Afrocyclus gen. nov. Revised species descriptions are given for seven species. Two species, C. meredithae Bruggen, 1983 and C. chirindae Bruggen, 1986 both from north of South Africa, are removed from Chondrocyclus. Twelve new species are described: C. herberti sp. nov., C. silvicolus sp. nov., C. amathole sp. nov., C. pondoensis sp. nov., C. devilliersi sp. nov., C. pulcherrimus sp. nov., C. cooperae sp. nov., C. langebergensis sp. nov., C. kevincolei sp. nov., A. oxygala gen. et sp. nov., A. potteri gen. et sp. nov. and A. bhaca gen. et sp. nov. This is the first detailed systematic revision of an Afrotropical cyclophorid group to include morphological and molecular data. This study complements research on other taxa of low-vagility forest-dwelling habitat specialists by providing comparative distribution data for an independent, widespread group. Such evidence is urgently needed for conservation of South Africa’s threatened forest biome.

A New Species

The classification of the superfamily Psylloidea is revised to incorporate findings from recent molecular studies, and to integrate a reassessment of monophyla primarily based on molecular data with morphological evidence and previous classifications. We incorporate a reinterpretation of relevant morphology in the light of the molecular findings and discuss conflicts with respect to different data sources and sampling strategies. Seven families are recognised of which four (Calophyidae, Carsidaridae, Mastigimatidae and Triozidae) are strongly supported, and three (Aphalaridae, Liviidae and Psyllidae) weakly or moderately supported. Although the revised classification is mostly similar to those recognised by recent authors, there are some notable differences, such as Diaphorina and Katacephala which are transferred from Liviidae to Psyllidae. Five new subfamilies and one new genus are described, and one secondary homonym is replaced by a new species name. A new or revised status is proposed for one family, four subfamilies, four tribes, seven subtribes and five genera. One tribe and eight genera / subgenera are synonymised, and 32 new and six revised species combinations are proposed. All recognised genera of Psylloidea (extant and fossil) are assigned to family level taxa, except for one which is considered a nomen dubium.

Morphological And Molecular Data

A recent phylogenetic study of the scale insect tribe Iceryini (Hemiptera: Coccoidea: Monophlebidae) based on morphological and molecular data led to a revised generic classification, including redefinition of three genera, one of which was Crypticerya Cockerell. The new concept of Crypticerya encompasses 22 described species, all of which are found in the New World. Nine species are scattered throughout the deserts of the southwestern United States and Mexico. Here these species are redescribed and one new species, Crypticerya bursera sp.nov. is described from Baja California, Mexico. The adult female and first-instar nymph are illustrated for nine of the 10 species. A key to the adult females of the southwestern species and morphologically similar species of Crypticerya is provided.

A New Species

A new trechine species Aphaenops parvulus sp. n. (Carabidae, Trechini) is described from Esjamundo cave in the Pyrenees of Huesca, Spain. The new species belongs to the subgenus Aphaenops (sensu stricto), but differs from its closest congeners by the small size—it is the smallest species of the group—and characters of the aedeagus. Molecular data based on fragments of a mitochondrial (COI) and a nuclear (LSU) genes recognised Aphaenops parvulus sp. n. as a sister taxon to A. eskualduna Coiffait. Aphaenops eskualduna is reported from Spain with precision for the first time.

Basal Position

Caiophora is a taxonomically difficult, nearly exclusively Andean genus of the largely South American family Loasaceae subfam. Loasoideae. Elevational distribution and flower morphology argue for a relatively basal position of loasoid Caiophora in the genus. Caiophora has not been revised since 1900, and details of their morphology, distribution and species delimitation are incompletely understood. The Caiophora pterosperma-group clearly belongs to Caiophora based on habit, fruit morphology, karyology and molecular data, but is florally similar to members of the closely allied genera Loasa and Scyphanthus. The Peruvian members of the Caiophora pterosperma-group are here revised. Three species are recognized: C. pterosperma, endemic to the departments of Junín and Pasco (including C. smithii, C. serropetala and C. pavonii), C. stenocarpa from the departments Cuzco and Huancavelica, and the new species Caiophora dederichiorum, endemic to the department of Ancash. All three species occur at low elevations for the genus (down to 2200 m a.s.l.) and in seasonally dry habitats, unlike most representatives of the genus (usually found in mesic habitats at higher elevations). A key to the Peruvian members of the group, diagnoses, drawings and photographs are provided for all species recognized.

16S Sequence

Three new species of the genus Amynthas are described from Guangxi Province, China. They are named A. dissimilis sp. nov., A. anteporus sp. nov. and A. marsupiformis sp. nov. All of them have two pairs of spermathecal pores in 6/7–7/8, and belong to the tokioensis-group. Their morphological characteristics are compared to similar species in tokioensis-group from China and other Asian countries. In addition, the mitochondrial COI and 12S-tRNA-Val-16S sequence of three new species were determined, then pairwise distances between species were calculated. Both morphological and molecular evidences could easily distinguish the new species from earthworms previously reported in the tokioensis-group.

The genera Boonea Robertson, 1978, Chrysallida Carpenter, 1856, Fargoa Bartsch, 1909, Ivara Dall & Bartsch, 1903, Mumiola A. Adams, 1863, Odostomella Bucquoy, Dautzenberg & Dollfus, 1883, Parthenina Bucquoy, Dautzenberg & Dollfus, 1883 and Trabecula Dall & Bartsch, 1909 from Brazil are reviewed. Boonea jadisi (Olsson & McGinty, 1958), Boonea seminuda (C. B. Adams, 1839), Chrysallida gemmulosa C. B. Adams, 1850, Ivara terryi (Olsson & McGinty, 1958), Fargoa bushiana Bartsch, 1909, Mumiola gradatula (Mörch, 1876) and Odostomella carceralis Pimenta, Absalão & Alencar, 2000 are confirmed to occur in Brazil. We also present the first records of Parthenina varia (Odé, 1993), Odostomella fonteini (Jong & Coomans, 1988) and Trabecula krumpermanni (Jong & Coomans, 1988) from the region, all, new combinations. Two species, previously reported from the Brazilian coast, could not be confirmed: Boonea bisuturalis (Say, 1822) and Boonea impressa (Say, 1822). Odostomella cf. doliolum (Philippi, 1844) and Parthenina cf. interspatiosa (Linden & Eikenboom, 1992), originally described from the eastern Atlantic, are here recorded from Brazil, although their status remains dubious because of lack of information on their biology and due to lack of morphological and molecular data. One new species is described: Boonea scymnocelata, which can be distinguished from the similar species B. seminuda by its smaller size and immersed protoconch, with no visible nucleus.
