Several botryllid colonies of the genus Botrylloides from the Mediterranean coast of Israel are analysed. Three species are described: B. leachii, which differs because of its smaller size, from specimens collected from other European seas and is considered a case of dwarfism due to the particular hydrological conditions of the study area; B. anceps, a species originally described from the Indo-Pacific region, which probably migrated from the Red Sea; and Botrylloides israeliense, a new species. The distinction between the genera Botryllus and Botrylloides is discussed, and the original Milne-Edwards diagnosis based on differences in the structure of the system is recognised as still valid. Lastly, the diagnostic features usually employed in specific taxonomic determinations of Botryllinae are analysed.

A New Species

A new species of Amphipoda, Psammogammarus caesicolus, is described from interstitial, anchihaline waters in Blauwbaai cave, Curaçao, Netherlands Antilles. By the morphology of the third uropod, the new species links the somewhat aberrant Ps. longiramus from the Red Sea with the type-species of the genus, Ps. coecus, from the Mediterranean.

A New Species

A new species of shrimp-goby was collected at depths of 60–80 m off the southern Israeli Mediterranean coast. A unique ‘DNA barcoding’ signature (mtDNA COI and Cytb) revealed that it differs from any other previously bar-coded goby species clustered phylogenetically with the shrimp-gobies group, in which Cryptocentrus is the most speciose genus. A morphological study supported the assignment of the fish to Cryptocentrus and differentiated the new species from its congeners. The species is described here as Cryptocentrus steinhardti n. sp. However, the present phylogenetic analysis demonstrates a paraphyly of Cryptocentrus and emphasizes the need for revision of the genus based on integrating morphological and genetic characteristics. This finding constitutes the third record of an invasive shrimp goby in the Mediterranean Sea. An intriguing ecological issue arises regarding the possible formation of a fish-shrimp symbiosis in a newly invaded territory. Describing an alien tropical species in the Mediterranean prior to its discovery in native distribution is an unusual event, although not the first such case. Several similar examples are provided in the present article.

A New Species

A new species of gobiid, Hazeus ingressus sp. nov. (Teleostei: Gobiidae) is described from the Levantine coast of Turkey. The species probably originates from the Red Sea and represents the 11th alien gobiid species in the Mediterranean Sea. The new species is distinguished from its Indo-Pacific congeners by a combination of the following characters: no dark blotch on the first dorsal fin; caudal fin coloration; scales in lateral series 25-28 (modally 27); second dorsal fin rays I,8; anal fin rays I,8-9; predorsal scales ctenoid 7; short, stout gill rakers 2+8. This finding suggests that the Lessepsian invasion intensely continues with the inclusion of the known species as well as undescribed species.

A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

A New Species

Pseudolebinthus is an intriguing genus of the tribe Xenogryllini with a distribtuion restricted to southeast Africa and characterized by unique morphological features such as asymmetrical male forewings and harp veins shaped as elongated balloons. It is sister group to the widely distributed genus Xenogryllus and has been known by two species, P. africanus Robillard, 2006 and P. whellani Robillard, 2006. The genus was initially diagnosed based exclusively on male morphological features. In this study, we add a new species to the genus, P. gorochovi Robillard sp. nov. and revise the diagnostic features using both male and female characters. We also update identification keys for the species of the genus.
