We here propose a new monotypic butterfly genus Scriptor Nakahara & Espeland, n. gen. to accommodate a new species, S. sphenophorus Lamas & Nakahara, n. sp., described and named herein. Scriptor sphenophorus n. gen. and n. sp.is a relatively common and widespread butterfly species which is recovered as a member of the so-called “Splendeuptychia clade” in the nymphalid subtribe Euptychiina, based on our molecular phylogenetic analysis using a maximum likelihood approach. Nevertheless, its sister group is not confidently resolved in any analysis, supporting a relatively distant relationship to any described genus as well as our decision to establish a new monotypic genus. We further discuss the proposed taxonomy in the light of frequent criticism of the description of monotypic taxa, as well as emphasize the importance of incorporating multiple evidence when describing new genera, illustrated by reference to several recent generic descriptions in this subtribe.

A New Species

Fourteen new species and six new genera of the molluscan class Monoplacophora are described from the Upper Cambrian Potosi and Eminence formations and the Lower Ordovician Gasconade Formation of the Ozark Uplift of Missouri and some new biostratigraphic horizons are introduced. A new superfamily, the Hypseloconellacea nom. trans. Knight, 1956, and a new family, the Shelbyoceridae, are named. The genus Proplina is represented by five new species: P. inflatus, P. suttoni from the Cambrian Potosi Formation, P. arcua from the Cambrian Eminence Formation and P. meramecensis and P. sibeliusi from the Lower Ordovician Gasconade Formation. A new genus and species in the subfamily Proplininae, Ozarkplina meramecensis, is described from the Upper Cambrian Eminence Formation. Four new monoplacophoran genera in the superfamily Hypseloconellacea and their species are described, including: Cambrioconus expansus, Orthoconus striatus, Cornuella parva from the Eminence Formation, and Gasconadeoconus ponderosa, G. waynesvillensis, G. expansus from the Gasconade Formation. A new genus in the new family Shelbyoceridae, Archeoconus missourensis, is described from the Eminence Formation and a new species of Shelbyoceras, S. bigpineyensis, is described from the Gasconade Formation.

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.

A New Species

Polysertularella polyseriata, gen. et sp. nov., a hydroid referable to family Sertulariidae, is described from the eastern part of the Sea of Okhotsk. The new taxa is characterized by: multi-serial (5–8 rows) placement of hydrothecae on both stem and branches; a hydrothecal rim with four small cusps; an operculum with four equal flaps similar to but more flattened than that of Sertularella. Gonothecae are transversely corrugated and resemble those of many species assigned to Sertularella and Symplectoscyphus. They arise from hydrothecae-like tubes on the basal part of the stem and are disposed in opposite pairs, as in species of Synthecium.Sertulariidae, the largest family in Hydrozoa and with representatives from marine environments worldwide, is relatively well known. Discovery of new genera in the family is relatively infrequent. A diagnosis of a new genus and a description of a new species are given in this paper.Diagnosis. Sertulariidae with erect, branched colonies, with branches resembling hydrocaulus. Hydrothecae arranged in 5–8 longitudal rows along hydrocaulus and branches; hydrothecal rim with four very low cusps separated by shallow embayments; operculum of four equal triangular valves, flattened rather than pyramidal; hydranth with abcauline caecum. Gonothecae oval with strong transverse corrugations and rings, occurring in opposite pairs on lower part of stem. Type species. Polysertularella polyseriata, sp. n., designated herein. Notes and differential diagnosis. In most genera of Sertulariidae, hydrothecae have an alternate to opposite biserial arrangement on branches, and especially on the stem. A few genera in the family, including Abietinaria Kirchenpauer, 1884, Thuiaria Fleming, 1828, Sertularia Linnaeus, 1758, and Staurotheca Allman, 1888 include some species with multi-serial rows of hydrothecae on branches and very rarely on the stem as well. The nominal genus Selaginopsis Allman, 1876, originally established for sertulariids having hydrothecae in more than two longitudinal rows, is no longer recognized as valid in some works because of its artificial composition and differences among included species in operculum structure (Peña-Cantero et al., 1997). However, no species with a multiserial arrangement of hydrothecae and four-flapped operculum (resembling Sertularella) has been known in the family until now.

A New Species

Speciose populations of small xanthoid crabs on offshore banks and reefs of the northern Gulf of Mexico include a new species that is not assignable to presently named genera. Morphological diagnoses of the new genus and species are underpinned by previously published gene sequence analyses, originally misattributed to another species but now known to apply to this taxon. Herein named Guinope tiara n. gen., n. sp., the species shows molecular phylogenetic affinities with the family Linnaeoxanthidae Števčić, 2005, an ally of panopeid and pseudorhombilid crabs. Specimens from Occulina banks off the Florida Atlantic coast, previously regarded to represent Garthiope barbadensis (Rathbun, 1921), are not that species but instead morphologically assignable to Guinope n. gen. Whether they represent variants of Guinope tiara n. gen, n. sp. or a second species of the genus awaits the collection of fresh materials for DNA analyses.

Two new genera and species of fossil whipspiders (Chelicerata: Arachnida: Amblypygi) are described from Tertiary and Cretaceous ambers of southern Asia.  Paracharonopsis cambayensis Engel & Grimaldi, new genus and species, preserved in Cambay amber of Ypresian age from western India is the first Tertiary and Asian fossil of the Paleoamblypygi, a highly relict taxon that includes the Late Carboniferous genus Graeophonus Scudder and the living West African species Paracharon caecus Hansen.  Paracharonopsis cambayensis is one of the few examples in Cambay amber of a biotic connection to Africa; most taxa show widespread or Laurasian distributions.  Kronocharon prendinii Engel & Grimaldi, new genus and species, is the first Cretaceous amber whipspider and putatively a sister group to the Phrynoidea (= Apulvillata).  The holotype female of K. prendinii is preserved with the remains of three nymphs near her, documenting the Early Cretaceous presence of the extended maternal care so distinctive for the order, and a behavioral repertoire widespread among arachnids.

Basal Structure

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

New Genus And Species

In preparation for upcoming studies, several new taxa of Australian Erotylinae (Coleoptera: Erotylidae) need to be described to make names available. New genera and species in Dacnini and Megalodacnini are described. Echinothallis banderbearella, new genus and species (Dacnini); Microdacne, new genus, with four new species (Dacnini), M. gloriousa, M. lamingtonia, M. nardia, M. styxia; and Episcaphula (Tropidoscaphula) megalodacnoides, new species (Megalodacnini). Variation of female terminalia and other characters in several genera are discussed regarding the monophyly and generic diversity of Dacnini.

A New Species

Because of the problematical identity and status of the type of the xeniid soft coral genus Cespitularia Milne-Edwards & Haime, 1850, the species C. stolonifera Gohar, 1938 is revised. Examination of the type colonies has led to the establishment of the new genus Unomia gen. n. which is described and depicted. This genus features a stalk, commonly divided into branches featuring a diffuse polypiferous part consisting of distal clustered polyps and proximal individual ones on the stalk or the basal membranous part of the colonies. The sclerites are ellipsoid platelets composed of dendritic calcite rods whose tips are distinct on the surface of the platelets. Freshly collected material from Venezuelan reefs where the species is invasive was subjected to molecular phylogenetic analysis, the results of which substantiate the taxonomic assignment of the new genus under U. stolonifera comb. n. A new species, U. complanatis, from Japan and Green Island (Taiwan) is described and further illustrates the extent of the interspecific morphological variation within the genus. The results reveal that the biogeographic distribution of Unomia gen. n. includes Pacific Ocean reefs in addition to the previously reported invaded Caribbean reefs.

A new genus and species of basal cyclostome Braconidae is described and figured from a male preserved in mid-Cretaceous amber from northern Myanmar.  <strong><em>Rhetinorhyssalus morticinus</em></strong> Engel, new genus and species, is interesting for its combination of primitive features such as a minute apical costal cell and anal stubs in the forewing, while lacking 2Cu in the hind wing, a putatively derived trait.  As such, the genus may represent a lineage diverging from the braconid stem subsequent to many protorhyssalines, while remaining basal relative to generalized cyclostome groups such as Rhyssalinae.  In addition, the Late Cretaceous <em>Diospilus allani</em> Brues, in Campanian Canadian amber, is transferred to <strong><em>Diorhyssalus</em></strong> Engel, new genus, and its similarity to <em>Rhetinorhyssalus</em> is discussed.  This transfer results in the new combination, <em>Diorhyssalus allani</em> (Brues).  Both genera are tentatively considered as subfamily <em>incertae sedis</em>.
