A new lacewing species of the Chrysoperla carnea species-group from central Asia associated with conifers (Neuroptera: Chrysopidae)

ABSTRACT

Chrysoperla duellii sp. nov. is discovered, associated with coniferous vegetation, in the Kyrgyz Republic in central Asia, co-occurring with two other cryptic species of the Chrysoperla carnea-group. It is distinguished by its courtship duetting song, which exhibits a uniquely complex multi-volleyed temporal and tonal structure but is nevertheless noticeably convergent on the species-specific song of another conifer-associated member of the carnea-group, C. downesi (Smith), from North America. The song of C. duellii also shows some superficial similarity to those of European/north African C. mediterranea (Hölzel) and southern Californian C. calocedrii Henry et al., both of which, like C. duellii, prefer conifers and exhibit dark-green adult body pigmentation. The new species is herein formally described as Chrysoperla duellii Henry, Taylor and Johnson and is shown to be diagnosable by song and morphology from all other known members of the Chrysoperla carnea-group. Results of restriction site-associated DNA sequencing (RADseq) of C. duellii and five other carnea-group species strongly reject the hypothesis that similar songs and dark-green body colour among the four conifer-associated species are due to common ancestry, instead supporting independent, parallel acquisition of such features.http://www.zoobank.org/urn:lsid:zoobank.org:pub:4CA5BE5F-B4B9-4A7D-A801-C9AE1E895D0B

Erection of Unicapsulocaudum mugilum gen. et sp. nov. (Myxozoa: Ceratomyxidae) based on its morphological and molecular data

Unicapsulocaudum mugilum gen. et sp. nov. was isolated from the gallbladder of marine Mugil cephalus L., 1758 from the coast of Xiamen, East China Sea, China. Morphological studies indicated that its spores are 2.9 ± 0.3 μm long and 25.4 ± 3.8 μm thick, each with a single pyriform polar capsule (5.2 ± 1.2 μm long and 2.6 ± 0.3 μm thick) positioned inside the bulky anterior end, and containing polar filaments with two turns. The spore is distinct from that of all other known myxozoans in having an ophidian-like form with a horn-like protuberance and a long tapering tail. Molecular studies indicated that the sequence of its small subunit ribosomal DNA (SSU rDNA) does not match any myxozoans sequenced to date. Molecular phylogenetic studies based on both Bayesian and maximum likelihood methods indicated that Unicapsulocaudum mugilum sp. nov. clustered with Ceratomyxa amazonensis, Ceratomyxa tunisiensis, Ceratomyxa leatherjacketi and Myxodavisia bulani as an older evolutionary ceratomyxid lineage. Considering its morphological characters, habitat and phylogenetic relationships with other main Ceratomyxidae species, we propose the erection of a new genus Unicapsulocaudum in Ceratomyxidae.

Stephonyx californiensis sp. nov. (Amphipoda: Lysianassoidea: Uristidae), a new bathyal scavenger species from the Central Gulf of California,Mexico, and comments on the bathymetric and geographic distribution of the Stephonyx species group

A new species of scavenger amphipod of the genus Stephonyx is described and illustrated. The specimen was caught at 1150 m depth with a modified rectangular lobster trap positioned on the sea bottom in the central Gulf of California, Mexico. The new species is characterised by the absence of eyes; the lateral cephalic lobes medially developed and acute; antennae subequal in length; gnathopod 1 chelate, dactylus simple with three distal stout setae, inner margin sinuous with minute setae; gnathopod 2 subchelate, carpus with ventral margin crenulate, propodus subovate, palm deeply excavate, and dactylus slightly shorter than palm; maxilliped inner plate laceolate, with seven marginal nodular robust setae, distally; telson, each lobe with two dorsal robust setae, distal margin truncated, with one penicillate and two simple setae, in addition to two short spines. Stephonyx californiensis sp. nov. is morphologically similar to S. arabiensis, S talismani, S. laqueus and S. perexcavatus. The new species increases the number of Stephonyx species around the world to 14, with one species inhabiting from the continental shelf to abyssal depths (to 3000 m), 11 species occurring in bathyal depths (201–2000 m), and two other species restricted to abyssal depths (2001–4000 m).

A new genus and two new species of Pudeoniscidae Lemos de Castro 1973 (Crustacea: Isopoda: Oniscidea) from Brazil

To date, the family Pudeoniscidae includes six species and three genera, Pudeoniscus, Brasiloniscus and Iansaoniscus, with distributions restricted to Brazil. Here, we redefine the family Pudeoniscidae based on the discovery of a new genus and two new species, Oxossioniscus pataxo sp. nov. and Oxossioniscus akoko sp. nov., from the Brazilian Atlantic forest in the state of Bahia, and on the examination of Pudeoniscus birabeni and Pudeoniscus obscurus. Moreover, P. obscurus is re-described and new records are provided for P. birabeni.

Two new nematodes,Pseudelzalia longiseta gen. nov., sp. nov. and Paramonohystera sinica sp. nov. (Monhysterida: Xyalidae), from sediment in the East China Sea

Pseudelzalia longiseta gen. nov, sp. nov. and Paramonohystera sinica sp. nov. from subtidal sediment in the East China Sea are described. Pseudelzalia is characterized by 6 labial papillae and 10 cephalic setae, cylindrical buccal cavity, elongate (>2 anal body diameter) spicules, and conico-cylindrical tail devoid of terminal setae. It differs from Elzalia by the absence of terminal setae. Pseudelzalia longiseta sp. nov. is 647–853 μm long, has 7–8 μm long cervical setae, 11–14 μm long caudal setae, 25–41 μm long spicules about 2.1–2.7 anal diameter, and pointed tail-tip. Paramonohystera sinica possesses 12 cephalic setae, a character found in four congeners: Paramonohystera buetschlii (Bresslau and Schuurmans Stekhoven in Schuurmans Stekhoven, 1935, Paramonohystera pilosa Boucher, 1971, Paramonohystera concinna Lorenzen, 1977 and Paramonohystera halerba Fadeeva and Belogurov, 1987. It differs from P. buetschlii by shorter body (933–1023 μm versus 2000–2200 μm); from P. pilosa by the much shorter spicules (79–88 μm versus 167 μm) and narrower head (13–16 µm versus 32 µm); from P.concinna by smooth cephalic setae (versus segmented); and from P. halerba by the absence of two rows of setae on the ventral side of the tail (versus present). Based on the evaluation of nominal species, we recognize 14 valid species and provide an emended diagnosis and a tabular key for Paramonohystera.

On the genus Racekiela in Mexico: molecular and morphological description of Racekiela cresciscrystae n. sp.

ABSTRACT

In Mexico, there are currently two known species of Racekiela: R. ryderii and R. montemflumina. Here we describe a new species from high-altitude streams in central and southern Mexico. Racekiela cresciscrystae sp. nov. presents two morphotypes: thick encrusting with raised ridges or lobose outgrowths at the surface and dark green in colour, or lime-green encrustations. The new species as megascleres presents microspined oxeas from 200 to 300 µm long, some centrotylote, or with malformations. Gemmules are spherical with a tri-layered theca, constituted by radially embedded birotules and pseudobirotules. The birotules have longer shaft than the rotule diameter, which is flat, and some slightly umbonate. Pseudobirotules of typical morphology have strongly or somewhat spined shaft. Spines can be straight or hooked. The species also presents other type of pseudobirotules, which are umbonate and with only small warts, instead of spines. DNA sequences from the nuclear ITS1-5.8-ITS2 region were sequenced from the holotype and a paratype of the new species to determine their phylogenetic relationships with other members of the family Spongillidae. Tree topologies (Bayesian Inference and Maximum Likelihood) were consistent in showing Racekiela creciscrystae sp. nov. as a sister clade of R. montemflumina confirming its allocation in a monophyletic genus Racekiela. A comparison with all the Racekiela species described so far is also included. This paper increases the number of species of freshwater sponges in Mexico, and confirmed that Racekiela is a monophyletic genus with morphological characters very well defined.

Zenkevitchiidae fam. nov. (Crustacea: Gammaroidea), with description of new subterranean amphipods from extremely deep cave habitats

Previous phylogenetic analysis based on combined mitochondrial and nuclear gene sequences detected paraphyly of the Typhlogammaridae. To test this hypothesis a portion of large subunit (LSU-rDNA) gene sequences were obtained for typhlogammarid species from Caucasus. The Bayesian approach to LSU-rDNA sequences provided evidence for an independent origin of the Dinaric and Caucasus ‘typhlogammarid’ clades. A new family, Zenkevitchiidae fam. nov., is proposed to reconcile the observed phylogeny with the concept of monophyly. Using light microscopy, two mouthpart morphotypes of the Zenkevitchiidae fam. nov. species with quite different setae are identified. Taking into account these two morphotypes, a new classification is proposed – Adaugammarus revazi comb. nov., and Adaugammarus sandroruffoi comb. nov. Additionally, two new stygobiont zenkevitchiid amphipod species – Adaugammarus kasiani sp. nov. and Kruberia relicta sp. nov. – are described from Krubera Cave in Abkhazia. A distribution map and an identification key for the Zenkevitchiidae fam. nov. species of Transcaucasia are provided.
