The worldwide ground-spider genus Drassodes is among the most diverse in the family Gnaphosidae, but it currently includes many species which do not show characters typical of Drassodes sensu stricto. The species belonging to the hypocrita-group of Simon, recently transferred to the genus Drassodex, are revised and redescribed: Drassodex hispanus, D. heeri, D. hypocrita, D. fritillifer, D. cervinus and D. validior. Lectotypes are here designated for D. cervinus and D. validior. The subspecies D. hispanus lesserti is also included and elevated to species rank. Three new species are described, D. granja sp. nov. from Spain, D. drescoi sp. nov. and D. simoni sp. nov. from the western part of the Alps. Representatives of Drassodex mainly occur in mountain systems in western Europe.

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

AbstractThe larvae of Anischia Fleutiaux and Perothops Laporte are described. Cladistic analyses based on adult and larval morphology, as well as CO1 sequence data, place both genera in the Eucnemidae clade within the Elateroidea (sensu stricto). The subfamily Anischiinae Fleutiaux, 1936 is placed in the family Eucnemidae in a clade containing the more derived eucnemid subfamilies (Melasinae, Eucneminae and Macraulacinae), while Perothops and Phyllocerus Lepeletier & Serville represent subfamilies basal to the remaining eucnemid taxa. The genus Afranischia Basilewsky, 1955 is synonymized with Anischia Fleutiaux, 1896, and Anischia boliviana Fleutiaux is selected as the type species of the latter. Three new species are described: Anischia bicolor (New Caledonia), Anischia kuscheli (New Caledonia) and Anischia monteithi (NE Australia), and Anischia stupenda Fleutiaux, 1897 is recorded from Australia. Anischia crassicornis Champion, 1897 is synonymized with Anischia mexicana Fleutiaux, 1896. One new combination is made, Anischia ruandana (Basilewsky, 1955).

Definition Of

Sponges of the genus Leucascus are frequently recognised as possessing anastomosed tubes with choanocytes, and cortical and atrial membranes with pinacocytes. In the last years, five species of other genera were transferred to Leucascus, and several other species were suggested but not formally included in this genus. In the present work, all these species accepted or suggested as Leucascus were revised. According to our results, Leucascus is now composed of nine species: L. clavatus, L. leptoraphis comb. nov., L. lobatus, L. neocaledonicus, L. protogenes comb. nov., L. roseus, L. simplex (type species), L. albus sp. nov., and L. flavus sp. nov. The presence of spines in the apical actine of the tetractines had never been observed in Leucascus, but it was found in all species with tetractines in their skeletons. Some species were transferred from Leucascus to the genus Ascoleucetta, which is revalidated here based on important differences in the cortex. Modifications are also proposed in the definition of both genera. Based on our results, the family Leucascidae is now composed of Ascaltis, Leucascus and Ascoleucetta.

Three New Species

The New Zealand skink fauna is highly diverse and contains numerous cryptic, undescribed or hitherto undiscovered species. We completed a taxonomic revision of the cryptic skink (Oligosoma inconspicuum) species complex using molecular (550 bp of the ND2 mitochondrial gene) and morphological analyses. Four new species are described, with each diagnosable by a range of morphological characters and genetic differentiation from several closely related species: O. inconspicuum (sensu stricto), O. notosaurus, O. maccanni, O. stenotis and O. grande. Oligosoma tekakahu sp. nov. is restricted to Chalky Island in Fiordland, and is most closely related to O. inconspicuum and O. notosaurus. The other three new species are restricted to particular mountainous regions in central and western Otago (O. burganae sp. nov., Lammermoor and Rock and Pillar Ranges; O. toka sp. nov., Nevis Valley; O. repens sp. nov., Eyre Mountains) and are most closely related to O. stenotis and O. grande. We also re-described O. inconspicuum. Two proposed new taxa, the ‘Big Bay’ skink and ‘Mahogany’ skink, were found to represent Westland/Fiordland populations of O. inconspicuum rather than distinct taxa. We discuss the evolutionary and phylogeographic implications of cryptic and ‘anti-cryptic’ species within the O. inconspicuum species complex, and suggest that morphologically aberrant populations are the result of local adaptation to novel selective regimes.

Gippsicola Hogg is one of the four genera included in the family Segestriidae. Currently this monotypic Australian genus is represented by Gippsicola raleighi Hogg, 1900, a species described based on an immature specimen from Victoria, Australia. In this work we present a taxonomic revision of this genus, with an elucidative diagnosis, redescribing G. raleighi based on detailed morphologic characters of adult male specimens. Also, we are describing three new species: Gippsicola robusta n. sp. and G. lineata n. sp., both represented by males and females, and G. minuta n. sp., only known by the male. We provide some enlightenment on the systematics of Gippsicola and putative synapomorphies for the subfamily Segestriinae.

Three New Species

Currently there are three species (i.e., traditional morphospecies) in Canada assigned to the genus Ralfsia sensu lato, which we establish is not monophyletic even after excluding “species” now known to apply to alternate stages in the life histories of non-ralfsialean species. These species include R. fungiformis (Gunnerus) Setchell & N.L.Gardner and R. pacifica Hollenberg in the Pacific, and R. fungiformis and R. verrucosa (J.E.Areschoug) J.E.Areschoug in the Atlantic. However, a DNA barcode survey of Ralfsiales in Canada using the markers COI-5P and rbcL-3P revealed five genetic groups assignable to Ralfsia sensu stricto (i.e., includes only species assigned to this genus based on phylogenetic analyses). Further complicating matters, of the three species listed previously as occurring in Canada only the type species R. fungiformis is assignable to Ralfsia sensu stricto. Ralfsia pacifica and R. verrucosa did not group with the generitype and thus are not assignable to Ralfsia sensu stricto; further, they did not group with the family Ralfsiaceae. They will be presented in a subsequent manuscript. The four other genetic groups in Canada assignable to Ralfsia sensu stricto are new species of which three are described here: Ralfsia robertii sp. nov., Ralfsia tenebris sp. nov., and Ralfsia unimaculata sp. nov. The fourth consisted of a single sterile specimen from Haida Gwaii, British Columbia, and was not characterized.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Three New Species

Three new species of Chrysomelidae with extraordinary extensions of the male mandibles are described: Scaphodius drehu sp. nov. and S. ferox sp. nov. (Cryptocephalinae), from New Caledonia, and Chaloenus gajah sp. nov. (Galerucinae), from Borneo. Designation of the type species of Chaloenus Westwood, 1861, is clarified. Synonymy of Scaphodius Chapuis, 1874, with Nyetra Baly, 1877, is supported. Four species of Ditropidus Erichson, 1842, described from New Caledonia, but hitherto regarded as nomina nuda, are shown to be available and are placed in Scaphodius: S. aeneus (Fauvel, 1907), comb. nov., S. nitidus (Fauvel, 1907) comb. nov., S. striolatus (Fauvel, 1907) comb. nov., S. sulcatus (Fauvel, 1907) comb. nov. Ditropidus opacicollis Fauvel, 1907, is also transferred to Scaphodius, as S. opacicollis (Fauvel) comb. nov. The genus Ditropidus does not occur onNew Caledonia. Male mandible enlargment in the Chrysomelidae is reviewed: it is common in Cryptocephalinae, but otherwise restricted to a few species of Chrysomelinae, Eumolpinae and Galerucinae. Possible reasons for its distribution in the Chrysomelidae are discussed.
