XXX.—A new Cicada from Arabia

Summary

Carebara nests occur in between 2% and 10% of Macrotermes mounds, but can also occur well away from mounds. A brood of alate ants is regularly produced ready to fly in the short rains (November) but flights can also take place in the long rains (April). Male and female alates are usually produced in separate nests. After the flight, male alates seek out the females, and several males appear to mate with one female.

Dealate female ants exposed to Macrotermes workers remained passive and elicited no aggression. Fecundated female ants reared broods of about 1000 workers after 39 days in the laboratory. These workers were able to overpower, kill and eat the much larger workers of Macrotermes.

New occurrences and host records for two species of parasitic isopods (Isopoda,Cymothoida, Bopyridae) associated with caridean shrimps (Decapoda,Caridea) from Brazil

ABSTRACT

Two species of bopyrid isopods of the Bopyrinae subfamily are recorded from new localities and hosts in northeastern Brazil. Parabopyrella lata (Nierstrasz and Brender à Brandis, 1929) was recorded from the state of Ceará, found for the first time parasitising the caridean shrimp Alpheus packardii Kingsley, 1880. In addition, Probopyrus cf. pandalicola (Packard, 1879) is recorded from the state of Bahia, parasitising the palaemonid shrimp Palaemon northropi (Rankin, 1898). Taxonomic comments are provided for each species.     

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.

Classical Biological Control of Bemisia tabaci in the United States. By Juli Gould,Kim Hoelmer & John Goolsby

ABSTRACT

The present study describes two new genera, six new species and three new records from the Sea of Marmara. The new genus Marmara gen. nov. belonging to the family Sagartiidae is mainly characterized by having conspicuous muscular belts along the column and the absence of suckers and tenaculi on the body wall. The genus Charisactis gen. nov. belonging to the family Condylanthidae is mainly characterized by having an atypical mesentery arrangement, single siphonoglyph and homotrichs in tentacles. The other species newly described from the Sea of Marmara belong to the families Diadumenidae (one species from deep waters), Halcampoididae (one species from shallow waters), Edwardsiidae (one species from shallow waters) and Epizoanthidae (one species from deep waters). Three species, namely Epizoanthus arenaceus (family Epizoanthidae), Rolandia coralloides (family Clavulariidae) and Virgularia sp. (family Virgulariidae) are reported for the first time from the Sea of Marmara. The external and internal anatomical features as well as cnidom structures of the species are presented and discussed with the closely related species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:51DA9869-D786-4A8A-8C1F-62DC1BB67923     

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.

A new genus and species of Caprellidae (Crustacea: Amphipoda) from Kiribati

ABSTRACT

Luisacaprella eliae gen. nov, sp. nov. (Crustacea, Amphipoda, Caprellidae) is described bwct ased on specimens collected from Kiribati, Pacific Ocean. The new genus is close to Aciconula but can be mainly distinguished by the following characteristics: (1) pereonites 6 and 7 are fused in Luisacaprella gen. nov. while they are separated in Aciconula; (2) the setal formula of mandibular palp is 2-x-1 in Luisacaprella and 1-x-1 in Aciconula; (3) pereopods 3 and 4 are two-articulate in males and females of Luisacaprella, whereas there is sexual dimorphism in Aciconula, and males have pereopods 3 and 4 two-articulate while females have pereopod 3 two- or three-articulate and pereopod 4 four-articulate. The new species L. eliae is additionally characterised by its tiny size (<3 mm). The new taxon was collected from dead branching coral of shallow waters (3–32 m). Further studies targeting small caprellids which could easily be overlooked from substrates such as sediments and dead corals are needed to properly understand the global caprellid diversity of tropical and temperate areas.

Cienfuegia gen. nov. (Xyalidae) and Pseudoterschellingia gen. nov. (Linhomoeidae), two new genera of free‐living marine nematodes from the Caribbean Sea

Two new genera of nematodes are described from the Caribbean Sea. Cienfuegia gen. nov. belongs to the Xyalidae based on the position of the anterior gonad constantly left of the intestine, cuticle clearly striated, second and third circle of anterior sensilla inserted at the same level and buccal cavity surrounded by pharynx. The new genus is differentiated from other genera by the buccal cavity divided in two chambers and by the four cephalic setae being longer than the six outer labial setae. Within the Xyalidae, Cienfuegia shows most affinities with the genera Daptonema and Theristus. Pseudoterschellingia gen. nov. is placed within the Linhomoeidae on the basis of the presence of anterior rounded amphidial fovea, unarmed narrow buccal cavity, distinctive cardia and presence of apophysis of gubernaculum. Pseudoterschellingia is closely related to the genera Terschellingia and Terschellingioides, but is differentiated by the crypto‐spiral amphidial fovea, and conical buccal cavity surrounded by pharyngeal tissue.
