  • A new genus of soft coral (Octocorallia, Malacalcyonacea, Cladiellidae) and three new species from Indo-Pacific coral reefs
Title: A new genus of soft coral (Octocorallia, Malacalcyonacea, Cladiellidae) and three new species from Indo-Pacific coral reefs

Molecular systematic studies of the anthozoan class Octocorallia have revealed widespread incongruence between phylogenetic relationships and taxonomic classification at all levels of the Linnean hierarchy. Among the soft coral taxa in order Malacalcyonacea, the family Alcyoniidae and its type genusAlcyoniumhave both been recognised to be highly polyphyletic. A recent family-level revision of Octocorallia established a number of new families for genera formerly considered to belong to Alcyoniidae, but revision ofAlcyoniumis not yet complete. Previous molecular studies have supported the placement ofAlcyonium verseveldti(Benayahu, 1982) in family Cladiellidae rather than Alcyoniidae, phylogenetically distinct from the other three genera in that family. Here we describe a new genus,Ofwegenumgen. nov.to accommodateO. verseveldticomb. nov.and three new species of that genus,O. coronalucissp. nov.,O. kloogisp. nov., andO. collisp. nov., bringing the total number of species in this genus to four.Ofwegenumgen. nov.is a rarely encountered genus so far known from only a few locations spanning the Indian and western Pacific Oceans. We present the morphological characters of each species and use molecular data from both DNA barcoding and target-enrichment of conserved elements to explore species boundaries and phylogenetic relationships within the genus.

    The systematics of humble-in-appearance brown spiders (“marronoids”), within a larger group of spiders with a modified retrolateral tibial apophysis (the RTA Clade), has long vexed arachnologists. Although not yet fully settled, recent phylogenomics has allowed the delimitation and phylogenetic relationships of families within marronoids to come into focus. Understanding relationships within these families still awaits more comprehensive generic-level sampling, as the majority of described marronoid genera remain unsampled for phylogenomic data. Here we conduct such an analysis in the family Cybaeidae Banks, 1892. We greatly increase generic-level sampling, assembling ultraconserved element (UCE) data for 18 of 22 described cybaeid genera, including all North American genera, and rigorously test family monophyly using a comprehensive outgroup taxon sample. We also conduct analyses of traditional Sanger loci, allowing curation of some previously published data. Our UCE phylogenomic results support the monophyly of recognized cybaeids, with strongly supported internal relationships, and evidence for five primary molecular subclades. We hypothesize potential morphological synapomorphies for most of these subclades, bringing a robust phylogenomic underpinning to cybaeid classification. A new cybaeid genusSiskiyugen. nov.and speciesSiskiyu armillasp. nov.is discovered and described from far northern California and adjacent southern Oregon and a new species in the elusive genusCybaeozyga,C. furtivasp. nov., is described from far northern California.

    For the first time in 21 years, a new genus of cardiochiline braconid wasp, Orientocardiochiles Kang & Long, gen. nov. (type species Orientocardiochiles joeburrowi Kang, sp. nov. ), is discovered and described. This genus represents the ninth genus in the Oriental region. Two new species ( O. joeburrowi Kang, sp. nov. and O. nigrofasciatus Long, sp. nov. ) are described and illustrated, and a key to species of the genus, with detailed images, is added. Diagnostic characters of the new genus are analyzed and compared with several other cardiochiline genera to allow the genus to key out properly using an existing generic treatment. The scientific names validated by this paper and morphological data obtained from this project will be utilized and tested in the upcoming genus-level revision of the subfamily based on combined morphological and molecular data.

    This paper addresses the systematics of the New Zealand spiders of the family Malkaridae. Malkarids are small araneoid spiders that live primarily in the leaf litter and mosses of temperate and tropical wet forests in Australia and New Zealand, with the exception of a single species in southern South America and another in New Caledonia. We treat the New Zealand species of Malkaridae that are not members of the subfamily Pararchaeinae, a monophyletic group of 11 new species that we classify in 2 new genera (Tingotingo, gen. nov. and Whakamoke, gen. nov.) and a new subfamily (Tingotinginae, subfam. nov.). We describe, diagnose, illustrate and map the distribution of specimen records of these 11 new species of New Zealand Malkaridae: Tingotingo porotiti, sp. nov., T. pouaru, sp. nov., T. tokorera, sp. nov., T. aho, sp. nov., Whakamoke orongorongo, sp. nov.; W. tarakina, sp. nov.; W. guacamole, sp. nov.; W. hunahuna, sp. nov.; W. paoka, sp. nov.; W. heru, sp. nov.; and W. rakiura, sp. nov. We also treat the phylogenetic relationships of Malkaridae and use the results of our previous work on the molecular phylogeny of Araneoidea as the bases for the classification of the family. Tingotingo, gen. nov. and Whakamoke, gen. nov. are sister clades. Tingotinginae, subfam. nov. is the sister group of the Malkarinae plus Pararchaeinae clade. We further hypothesise and discuss the morphological synapomorphies of Malkaridae, Tingotinginae, subfam. nov. and the two new genera.

    Abstract

    A new monotypic genus in the ‘Archeuptychiaclade’XikrinBarbosa, Freitas, Siewert & Maríngen. nov.(Nymphalidae: Satyrinae: Euptychiina) is described to accommodate a new species,Xikrin ueharapradoiFreitas & Barbosagen. et sp. nov., in the highly diverse Satyrinae subtribe Euptychiina, based mainly on molecular data. To date, this species is known only from the region of Carajás, in the eastern Amazon rainforest. The phylogenetic relationship and taxonomy of this new taxon are discussed.
