All extant species of the planthopper genus Limois Stål (Hemiptera: Fulgoromorpha: Fulgoridae) were studied. One new species, Limois sordida sp. nov., is described and illustrated from China. Six known species are re-described and photos and illustrations of male genitalia are provided. A key to all extant species of this genus is also given.
Chaetopterus is a globally distributed genus of marine Annelida with a long history of taxonomic confusion. Here, we describe Chaetopterus bruneli sp. nov. from a depth of 350 m in the St. Lawrence Estuary, eastern Canada. The new species represents the northernmost record for Chaetopterus in the western Atlantic to date. The similar European species Chaetopterus norvegicus M. Sars, 1835 is resurrected from long-standing synonymy and redescribed from type material, and a lectotype is designated.
We present a comprehensive revision of the pholcid spider collection of M.A. González-Sponga, who between 1998 and 2011 described 22 new genera and 51 new species of Pholcidae from Venezuela. In addition, we treat the pholcid material collected during three expeditions to Venezuela conducted between 2002 and 2020. Of González-Sponga’s pholcid taxa we recognize three genera and 24 species as valid. We describe 43 new species (all from males and females) in one new and 13 previously described genera; four genera are newly recorded for Venezuela. We describe the previously unknown females of 15 species, present new records for 46 previously described species, synonymize one genus and one species, and correct numerous minor errors in previous publications on Venezuelan pholcids. At the generic level, the Venezuelan pholcid fauna now appears fairly well known, but available data on distribution and endemism suggest that many species remain undiscovered and undescribed. Despite the obvious gaps, our data are congruent with previous studies on other taxa that have the highest levels of endemism in the Venezuelan Andes, the Coastal Ranges, and the Guyana Highlands. The Falcón Region in particular shows a complex mosaic of biogeographic relationships with other regions. We provide new biological data on numerous species. We document the first cases of evolutionary microhabitat shifts in the genera Mecolaesthus Simon, 1893 and Priscula Simon, 1893. We document several cases of close congeners sharing localities, usually in slightly to conspicuously different microhabitats, sometimes apparently in identical microhabitats. We document several cases of color polymorphism, mostly intersexual, in Metagonia conica (Simon, 1893) both intersexual and among males. We document further cases of two rare phenomena in Pholcidae: use of specific non-silken structures for retreats (in Pisaboa Huber, 2000) and egg parasitism (in Priscula).
This paper treats the planthopper genus, Atracis Stål, 1866 (Flatidae: Flatoidinae) in China. Five new species, A. ocularia sp. nov., A. patefacta sp. nov., A. punctulata sp. nov., A. sphaerica sp. nov. and A. ungulata sp. nov., are described and a checklist of all its known species from China is provided.
The genus Teloneria Aczél, 1954 is resurrected from synonymy with Chaetonerius Hendel, 1913 to include four species: Teloneria apicata (Edwards, 1919) comb. nov., Teloneria bimaculata (Edwards, 1919) comb. nov., Teloneria juceliae Sepúlveda & Souza sp. nov. and Teloneria ladyae Sepúlveda & Souza sp. nov. Lectotypes for Telostylus apicatus Edwards, 1919 and its junior synonym, Telostylinus apicalis Enderlein, 1922, and for Telostylinus ornatipennis Enderlein, 1922, junior synonym of Teloneria bimaculata comb. nov., are designated. An identification key to Chaetonerius, Telostylus Bigot, 1859 and Teloneria, with emphasis on the identification of the species of Teloneria, illustrations and distribution data are provided.
Five new species of Peltonotellini (Caliscelinae) are described and illustrated: Bruchomorpha pseudodorsata sp. nov., Fitchiella brachyrhina sp. nov., Protrocha nigrilutea sp. nov. and P. punctatosa sp. nov. from Mexico, and Fitchiella zahniseri sp. nov. from Panama. Additionally, five previously described species are redescribed based on newly collected specimens: Aphelonema brevata Caldwell, 1945 (proposed original combination), Bruchomorpha decorata Metcalf, 1923, Bruchomorpha mormo Kirkaldy, 1907, Nenema virgata (Doering, 1941) and Protrocha nesolitaria (Caldwell, 1945). Bruchomorpha decorata is recorded from Panama for the first time. Redescriptions provide new information on the distribution of sensory pits and the first detailed descriptions of male and female terminalia for these species.
A new phylogenetic hypothesis is proposed for the relationships among the species within the genus Docosia Winnertz, 1863, based on a combined analysis of five DNA markers (28S, ITS2, COI, COII and CytB). Five new species are described, Docosia anatolica Ševčík sp. nov. from Turkey, D. japonica Kurina sp. nov. from Japan, D. peloponnensis Ševčík sp. nov. from Greece, D. svanetica Kurina sp. nov. from Caucasus and D. polyspina Kurina sp. nov. from the Russian Far East. New country records of the following species are presented: D. diutina Plassmann, 1996 (Turkey), D. flavicoxa Strobl, 1900 (Georgia), D. gilvipes (Haliday in Walker, 1856) (Georgia), D. kerkini Kurina & Ševčík, 2011 (Bulgaria), D. moravica Landrock, 1916 (Georgia), D. pannonica Lastovka & Ševčík 2006 (Georgia) and D. rameli Kurina & Ševčík, 2011 (Slovakia).
The Caucasian leucogeorgiinine genera Archileucogeorgia Lohmander, 1936 and Leucogeorgia Verhoeff, 1930 are revised, with Leucogeorgia being considered as a senior subjective synonym of Archileucogeorgia, syn. nov. The following new combinations are thus warranted: Leucogeorgia abchasica (Lohmander, 1936) and L. satunini (Lohmander, 1936), both comb. nov. ex Archileucogeorgia. All four previously described species, viz., L. longipes Verhoeff, 1930, L. abchasica, L. satunini and L. rediviva Golovatch, 1983, are redescribed based on new material, partly also on the type series, with a lectotype being designated for L. longipes. In addition, eleven new species of Leucogeorgia are described, both with normal (L. borealis sp. nov., L. gioi sp. nov., L. golovatchi sp. nov., L. lobata sp. nov., L. oculata sp. nov. and L. prometheus sp. nov.) and modified mouthparts (L. caudata sp. nov., L. mystax sp. nov., L. profunda sp. nov., L. redivivoides sp. nov. and L. turbanovi sp. nov., all clearly troglobionts). Additionally, a new monotypic genus, Martvilia gen. nov., is erected, with M. parva gen. et sp. nov. as the type species, another presumed troglobiont. An identification key to both genera and all 16 species of Caucasian Leucogeorgiini is presented. Several other members of this tribe are also re-examined, including a syntype male of Telsonius nycteridonis Strasser, 1976, from Greece, herewith designated as the lectotype. Troglomorphisms and mouthpart modifications, as well as the distributions and relationships within both Leucogeorgia and Leucogeorgiini, and a Leucogeorgiini species richness estimate for the western Caucasus are discussed.
Indian spider species currently assigned to Storena Walckenaer, 1805 are revised mostly based on the type material available in the National Zoological Collection, Zoological Survey of India, Kolkata. A new genus, Laminion gen. nov. is proposed to include four species; three are transferred from Storena: Laminion arakuensis (Patel & Reddy, 1989) gen. et comb. nov., Laminion birenifer (Gravely, 1921) gen. et comb. nov. and Laminion debasrae (Biswas & Biswas, 1992) gen. et comb. nov., whereas the fourth species is from Suffasia Jocqué, 1991: Laminion gujaratensis (Tikader & Patel, 1975) gen. et comb. nov. The species Storena tikaderi Patel & Reddy, 1989 syn. nov. is synonymised with L. birenifer gen. et comb. nov. Storena dibangensis Biswas & Biswas, 2006 and Storena indica Tikader & Patel, 1975 are transferred to Mallinella Strand, 1906. All the type material examined are imaged and redescribed. In addition, images of the type material of Storenomorpha joyaus (Tikader, 1970) are presented.
Microporella Hincks, 1877 is one of the most diverse genera of cheilostome bryozoans, containing more than 150 named species. Distributed globally since the early Miocene, the majority of species of Microporella have sheet-like colonies encrusting hard and / or ephemeral substrates, while a limited number of species have erect bifoliate colonies starting from an encrusting base. Herein, the four nominal species of erect bifoliate Microporella (M. bifoliata, M. hastigera, M. hyadesi and M. ordo) are revised, and one new Pliocene (M. tanyae sp. nov.) and three new Recent species (M. ordoides sp. nov., M. lingulata sp. nov. and M. modesta sp. nov.) are formally described. Furthermore, the lectotype and paralectotypes were designated for M. bifoliata and M. hastigera. An additional Recent species, Microporella sp. 1, is also described and illustrated but left in open nomenclature owing to the absence of ovicells in the single available fragment. Although the molecular phylogeny of Microporella has yet to be resolved, the diversity of character states present among the erect bifoliate species described here suggests that this colony growth-form is not monophyletic but has evolved on multiple occasions.
