“Typhloplanoida” (Platyhelminthes: Rhabdocoela) from the Indian Ocean,with the description of six new taxa

Seven typhloplanoids from the Indian Ocean are discussed; six of them are new to science. We place four of the new species within the Trigonostomidae. Gandalfia bilunata gen. nov. sp. nov. is characterized by a tubiform stylet and two semilunar structures in the afferent duct. Mahurubia clava gen. nov. sp. nov. has a gutter‐shaped stylet and a club‐shaped mouthpiece on the bursa. Parapharyngiella involucrum gen. nov. sp. nov. is characterized by a stylet in the form of a question mark and a bursal mouthpiece with a club‐shaped and a barrel‐shaped part. Poseidoplanella halleti gen. nov. sp. nov. is characterized by an unpaired ovary, a funnel‐shaped stylet connected with a plate, and a small, tubular bursal mouthpiece. Furthermore, new data are given on Ceratopera axi. The two other new species belong to the Typhloplanidae. Aegira annabellae gen. nov. sp. nov., a marine species, is characterized by a box‐shaped stylet and a long, pseudocuticularized ejaculatory duct. Castrada trispina sp., a freshwater species, has a copulatory bursa with three spines. Mahurubia clava gen. nov. sp. nov. and Parapharyngiella involucrum gen. nov. sp. nov. occur at Zanzibar, Tanzania. The other five species have been found on Kerguelen.

New damselfly hosts and species identification of an aquatic parasitoid Hydrophylita emporos (Hymenoptera: Trichogrammatidae) in Taiwan

ABSTRACT

The host–parasitoid relationship and species identity of aquatic parasitoids of two damselflies Coeliccia cyanomelas (Platycnemididae) and Psolodesmus mandarinus dorothea (Calopterygidae) from Fushan and Lienhuachih in Taiwan were studied using morphological characters and DNA barcoding sequences. The parasitoids reared from the damselflies’ eggs, and the field-collected parasitoids, were morphologically identified as Hydrophylita emporos (Trichogrammatidae), a recently described parasitoid of the damselfly P. m. mandarinus from Northern Taiwan. The CO1 (cytochrome c oxidase I) gene tree supported the identification as H. emporos, as well as all parasitoid samples from C. cyanomelas, P. m. dorothea and P. m. mandarinus. The sampled H. emporos populations did not differ genetically despite their different host associations. However, some genetic differences were found between H. emporos populations from Northern and Central Taiwan, indicating that the dispersal of H. emporos may be limited by geographical distances. Our results suggest that H. emporos can parasitise not only closely related sister subspecies, P. m. mandarinus and P. m. dorothea, but also phylogenetically distant species of another damselfly family, C. cyanomelas. This is the first record of multiple damselfly hosts for the aquatic parasitoid genus Hydrophylita. This finding implies that the host range of H. emporos and congeneric species may be broader than previously thought.     

A description of the song of Chorthippus cazurroi (Orthoptera: Acrididae) with notes on its taxonomic position and distribution

The highly characteristic calling and courtship songs of Chorthippus cazurroi are described for the first time and are used, together with a number of morphological characters, as a basis for discussing the differences between this species and C. pullus, C. pulloides, C. nevadensis and Omocestus llorenteae, with which it has been or might be confused. Despite the superficial resemblance between cazurroi and these species, clear and reliable characters are described for distinguishing it from all of them. The distribution of cazurroi is also discussed and it is suggested that its inclusion in the Libro Rojo de los Ortópteros Ibéricos as extinct or in danger is, as the authors of that work suspected, unduly pessimistic. A lectotype is designed from the type material of C. cazurroi.     

The marine green and brown algae of Rodrigues (Mauritius,Indian Ocean)

The marine benthic green and brown macroalgae of Rodrigues, collected during an expedition in October 2001, are documented and 18 of the 60 taxa of Chlorophyta (53 species) and 18 species of Phaeophyceae are illustrated. Fifty taxa of green and 12 taxa of brown algae are added to the existing species list of the island. Turf algae and smaller epiphytic species are not or are only sporadically included in this study. All records are listed with bibliographic, biogeographic, taxonomic and nomenclatural comments. Infrageneric identification keys are included. The new combination Caulerpa mexicana var. exposita is proposed and the discovery of a new Udotea species is mentioned. The algal flora of Rodrigues is of a typical Indian Ocean composition but appears to be relatively poor when compared to the nearby island of Mauritius.     

Two new species of Limnoriidae (Isopoda) from Papua New Guinea

Limnoria kautensis and Paralimnoria asterosa are two limnoriids new to science. They were found at a depth of 8–9 m in marine conditions burrowing in rainforest logs of timber species sufficiently dense to sink when lost during log-transporting operations. L. kautensis most closely resembles. L. pfefferi, from which it can be distinguished by the absence of a Y-shaped carina on pleonite 5, the bilobed nature of the lacinia mobilis of the mandible and differences in the proportions of the maxilliped, flagellum of antenna 2 and uropods. Paralimnoria asterosa differs from the only other member of its genus, P. andrewsi, in having a pronounced ring of basally-sheated radiating setae on pleonites 4 and 5 plus the pleotelson, and in details of the pattern of carinae, tubercles and depressions on the pleon and pleotelson.

Taxonomy of the Goliath beetle Goliathus orientalis Moser, 1909 (Coleoptera: Scarabaeidae: Cetoniinae)

The 16 names proposed for the central and eastern African Goliath beetle Goliathus orientalis Moser, 1909 Moser, J. 1909. Eine neue Lokalform von Goliathus giganteus Lam. Deut Entomol Z, 1909: 238 [Google Scholar], are reviewed and a complete synonymy is presented for the species. The earliest published name is Goliathus giganteus orientalis Moser, 1909 Moser, J. 1909. Eine neue Lokalform von Goliathus giganteus Lam. Deut Entomol Z, 1909: 238 [Google Scholar], type locality Lindi, Deutsch-Ostafrika, and so the correct name for the species is Goliathus orientalis Moser, 1909 Moser, J. 1909. Eine neue Lokalform von Goliathus giganteus Lam. Deut Entomol Z, 1909: 238 [Google Scholar]. Goliathus meleagris Sjöstedt, 1927a Sjöstedt, Y. 1927a. Goliathus meleagris n. sp. (Vorläufige Mitteilung). Entomol Tidskr, 48: 123 [Google Scholar], type locality Katanga, Congo Belge, is a synonym of G. orientalis. Populations of G. orientalis in the Usambara Mountains, Tanzania, may represent a distinct subspecies. The correct subspecific name for this form would be G. orientalis usambarensis Preiss, 1933 Preiss, P. 1933. Neue und bekannte afrikanische Cetoniinen mit besonderer Berucksichtigung der Fauna von Mongoumba. Verh Naturhist Ver Preuss Rheinl Westfalens, 90: 1–3. 70–92 + pls [Google Scholar]; the widely used name G. orientalis preissi Endrödi, 1951 Endrödi, S. 1951. Die arten und aberrationen der gattung Goliathus Lam. i. Folia Entomol Hung (n. s), 4: 29–56.  [Google Scholar], is a junior subjective synonym of G. o. usambarensis Preiss. Goliathus orientalis is re-described and characters are presented for separation of adults of G. orientalis from adults of the partially sympatric species Goliathus goliatus (L.), 1771 and Goliathus albosignatus Boheman, 1857.
