A New Species

1. A new species of the Ascothoracican genus, Bacca-laureus is described. It is distinguished by the possession of lateral processes which contain branches of the gut and of the gonads. 2. The orientation of the segmented body within the mantle is described, and a detailed description of the segmented body is given. 3. A description of the structure and method of attachment of the mantle is given, and of the structure of the lateral coils. 4. The nauplius larva, found within the lumen of the coils, is described. There is a possible further larval stage in some of the larger parasites. 5. The systematic position of the parasite, and the general relationships of the genus Baccalaureus are discussed.

A New Species

A synopsis of the genus Cnidoscolus is presented for the midwestern region of Brazil, which resulted from the analysis of about 1,200 specimens from 62 national and foreign herbaria, including type collections. Observations of populations in field were also made. Nine species are recognized, one of which, C. mcvaughii, is new to science. It is described and illustrated, and comments about its geographic distribution, morphological relationships, systematic position, phenology, and conservation status are provided, as well as images and a map. The other species are contrasted by a dichotomous key. Also, distributional information, maps, conservation evaluations, images and morphologically diagnoses are included. Eight synonymizations, one lectotypification, a neotypifcation, and the re-establishment of C. neglectus are proposed.

The genus Pselactus in the Cape Verde Islands is reviewed. Pselactus obesulus (Wollaston, 1867) from São Vicente is redescribed and P. strakai sp. nov. from São Nicolau is described. Both species are diagnosed and illustrated; their larvae are described, larval morphology is discussed and the current state of knowledge about immature stages of Cossoninae is summarized. The systematic position of the genus within Onycholipini is reviewed, and the placement of genus in Cossoninae is discussed. A short note on biogeography of Pselactus is provided.

Test Shape

The discovery of a new species,Cyclolampas altusnew species in the upper Callovian of Burgundy (France) leads to the systematic revision of the rare echinoid genusCyclolampasPomel, 1883. Two morphometric approaches are used jointly to describe and quantify variations in test shape: the analysis of linear measurements and the Elliptic Fourier shape analysis. Both analyses yield congruent results that highlight the amplitude of within-species variations and quantify the part due to allometry. Along with the description ofC. altus, the systematic position of species formerly assigned to the generaPygorhytisPomel, 1883 andCyclolampasis amended. Previously attributed to the genusPygorhytis,Cyclolampas castanea(Desor, 1858) is reassigned to the genusCyclolampason the base of new observations. Conversely, the examination of the Bajocian speciesPygorhytis kiliani(Lambert, 1909) andPygorhytis gillieroniDesor in Desor and de Loriol, 1872, which were previously assigned toCyclolampasnow supports their taxonomic reassignment to the genusPygorhytis. Finally, the two speciesCyclolampas verneuili(Cotteau, 1870) andCyclolampas cotteauiMintz, 1966 (nomen nudum) are considered junior synonyms of the genus type speciesCyclolampas voltzii(Agassiz, 1839). The questioned origin date of the genus, estimated either to the Bajocian or to the Oxfordian, is now clearly established to be upper Callovian. These new results fit well with the overall scheme of atelostomate echinoid evolution and migration to deep-sea environments during the Middle and Upper Jurassic.

A New Species

The Afrotropical species described as Trachyphloeini Lacordaire, 1863 were examined and their taxonomic status is revised. Atrachyphloeus Voss, 1962 is proposed as a junior synonym of Phaylomerinthus Schoenherr, 1842, Cathormiocerus africanus Hoffmann, 1965 as a junior synonym of Tapinomorphus sylvicola Voss, 1962 and Trachyphloeus pustulifer Voss, 1959 as a junior synonym of Platycopes tuberculatus Marshall, 1906. Atrachyphloeus convergens Voss, 1962 is transferred to the genus Phaylomerinthus Schoenherr, 1842, Trachyphloeus hardenbergi Marshall, 1923 and T. notulatus Boheman, 1842 to Glyptosomus Schoenherr, 1847, Trachyphloeus nanus Fåhraeus, 1871 to Pentatrachyphloeus Voss, 1974, Trachyphloeus pustulifer Voss, 1959 to Platycopes Schoenherr, 1823 and Trachyphloeus setiger Fåhraeus, 1871 to Phaylomerinthus Schoenherr, 1842. “Trachyphloeosoma” brevicolle Voss, 1974, “Trachyphloeus” brevis Boheman, 1842, “T”. nodifrons Hoffmann, 1968 and “T”. squalidus Boheman, 1842 are provisionally left in their current genera, but new genera for them will be described in future papers. The genus Phaylomerinthus Schoenherr, 1842 has been redefined and redescribed. Lectotypes for the following species are designated (current names added in brackets where different): Cathormiocerus africanus Hoffmann, 1965 (Tapinomorphus sylvicola Voss, 1962), Trachyphloeus hardenbergi Marshall, 1923 (Glyptosomus hardenbergi (Marshall, 1923)), Trachyphloeus nanus Fåhraeus, 1871 (Pentatrachyphloeus nanus (Fåhraeus, 1871)), Trachyphloeus notulatus Boheman, 1842 (Glyptosomus notulatus (Boheman, 1842)), Trachyphloeus pustulifer Voss, 1959 (Platycopes tuberculatus (Marshall, 1906)), Trachyphloeus setiger Fåhraeus, 1871 (Phaylomerinthus setiger (Fåhraeus, 1871)), “Trachyphloeus” brevis Boheman in Schoenherr, 1842 and “Trachyphloeus” squalidus Boheman in Schoenherr, 1842. Two paralectotypes of Cathormiocerus africanus Hoffmann, 1965 from Tanzania are described as a new species, Tapinomorphus franzi sp. n. All type specimens are illustrated.

The described species of the genus Dodecaceria are reviewed. Fourteen species are recognized and their diagnostic characters are given. A new species, Dodecaceria berkeleyi, is described from New Zealand where it is found boring in the shells of large gastropod molluscs. An outline is given of the nature of the skin pigments, which are similar to the arenicolochrome of lugworms. Asexual reproduction in the genus is reviewed, and an account is given of autotomy in D. berkeleyi, followed by regeneration to give rise to two individuals, a method of reproduction similar to that which occurs in the colonial tube builder Dodecaceria fistulicola. An advanced larval stage found in the burrows of D. berkeleyi is described.

The genus Ludioctenus Fairmaire, 1893 hitherto included only L. cyprius (Baudi di Selve, 1871) from the eastern Mediterranean and L. pakistanicus Schimmel & Tarnawski, 2012 from Pakistan. Here, we describe L. afghanicus sp. nov. from the Nuristan Province in eastern Afghanistan. The distribution and morphological diversity of Ludioctenus is discussed, main diagnostic characters for all species are figured, and an identification key to the species of this genus is provided. Female pregenital segments and genitalia are figured for the first time for Ludioctenus, and the systematic position of this genus and its relatives is discussed.

The mirine plant bug genus Neolygus Knight is reported from Nepal and North India for the first time, thus representing the first confident distributional record of this genus from the Himalayas. A new species, Neolygus machanensis, is described from Nepal. Two known members, N. bui Lu & Zheng and N. keltoni (Lu & Zheng), newly recognized as occurring in Nepal and/or North India, are diagnosed. Habitus images of live individuals and illustrations of the male genitalia are provided for all treated species. A checklist of the Old World species, and discussion of the systematic position and zoogeography of Neolygus are included. Neolygus partitus (Walker, 1873) [Capsus], N. mjohjangsanicus (Josifov, 1992) [Lygocoris], and Neolygus zebei (Günther, 1997) [Lygocoris] are proposed as new combinations.
