Abstract: The genus Maritrema Nicoll, 1907 (Platyhelminthes, Trematoda, Plagiorchiida, Microphallidae) comprises cosmopolitan species that predominantly parasitize birds. Although approximately 65 species have been described worldwide, including 6 for Argentina, molecular data referring to Maritrema species are still scarce worldwide, especially in South America. Unfortunately, this lack of references for nucleotide sequences is an obstacle to understanding the taxonomy and life cycles of trematodes, and impedes advancing our studies on the phylogeny and geographical distribution of these parasites. For that reason, we performed the molecular study of developmental stages of Maritrema bonaerense: cercariae (collected from the snail first intermediate host Heleobia australis, inhabiting Mar Chiquita lagoon) and metacercariae (collected from the crab second intermediate host Neohelice granulata, inhabiting Mar Chiquita lagoon and San Antonio Oeste, Argentina). The accordance between the ITS2 sequence of M. bonaerense cercaria from the snail H. australis and the sequences of metacercariae from the crab N. granulata was 100%, supporting previous findings of the life cycle of M. bonaerense based on morphological data. All Maritrema species are included in a monophyletic and well-supported clade. Maritrema bonaerense grouped more closely with Maritrema gratiosum. These findings contribute to the knowledge of digeneans in coastal marine ecosystems.

A new species of crayfish of the genus Cherax from Indonesian New Guinea (Crustacea, Decapoda, Parastacidae) https://zse.pensoft.net/article/94753/ Zoosystematics and Evolution 98(2): 411-425

DOI: 10.3897/zse.98.94753

Authors: Christian Lukhaup, Rury Eprilurahman

Abstract: A new species of the genus Cherax is described and illustrated. Cherax wagenknechtae sp. nov., endemic to the Beraur and Klasabun River drainages in the western part of the Kepala Burung (Vogelkop) peninsula, West Papua, Indonesia, is described, figured and compared with its closest relatives, Cherax pulcher Lukhaup, 2015. The new species may be easily distinguished from Cherax pulcher by the shape of the chelae, rostrum and body, and coloration.

Multigene phylogeny of the Indo–West Pacific genus Enosteoides (Crustacea, Decapoda, Porcellanidae) with description of a new species from Australia https://zse.pensoft.net/article/90540/ Zoosystematics and Evolution 98(2): 387-397

DOI: 10.3897/zse.98.90540

Authors: Alexandra Hiller, Bernd Werding

Abstract: The porcellanid genus Enosteoides Johnson, 1970, currently containing six species, was raised in the 1970s to contain aberrant Indo–West Pacific forms of the diverse and cosmopolitan genus Porcellana Lamarck, 1801. Here, we describe the most aberrant form as Enosteoides spinosus sp. nov., from the northeast and northwest coasts of Australia and present results on phylogenetic reconstructions of the genus, based on an 1,870 bp alignment of concatenated DNA sequences of three mitochondrial and one nuclear gene. The new species is peculiarly spiny and has a higher morphological affinity to the type species of the genus, E. ornatus (Stimpson, 1858), than to the other congeneric species. Our molecular results indicate that Enosteoides is not monophyletic. The new species and E. ornatus are encompassed in a clade, which does not share immediate common ancestry with the clade containing the other species of Enosteoides. This clade is more closely related to species of Porcellana and Pisidia. Relatively large interspecific genetic distances between and within the two clades, as compared to distances estimated in American pairs of species on each side of the Panama Isthmus, suggest ancient divergence, probably followed by extinction events or low speciation rate. Relatively large intraspecific distances between Australian populations of the new species of Enosteoides from geographically distant locations suggest some level of phylogeographic structure.

Review of Macropodia in the Black Sea supported by molecular barcoding data; with the redescription of the type material, observations on ecology and epibiosis of Macropodia czernjawskii (Brandt, 1880) and notes on other Atlanto-Mediterranean species of Macropodia Leach, 1814 (Crustacea, Decapoda, Inachidae) https://zse.pensoft.net/article/48342/ Zoosystematics and Evolution 96(2): 609-635

DOI: 10.3897/zse.96.48342

Authors: Vassily A. Spiridonov, Ulyana V. Simakova, Sergey E. Anosov, Anna K. Zalota, Vitaly A. Timofeev

Abstract: Macropodia czernjawskii (Brandt, 1880), described from the Black Sea, was ignored in the regional faunal accounts for more than a century, although it was recognised in the Mediterranean. Instead, M. longirostris (Fabricius, 1775) and M. rostrata (Linnaeus, 1761) were frequently listed for the Black Sea. We selected a lectotype and redescribed the species on the basis of the type series from the Crimean Peninsula and the new material collected in the Black Sea. Historical and new collections, as well as the analysis of publications, indicate that M. czernjawskii is the only Macropodia species occurring in the Black Sea. Molecular barcode (COI gene marker) data show that M. czernjawskii is a species well-diverged from other studied species of the group. Furthermore, M. parva van Noort & Adema, 1985 has very low genetic distances from M. rostrata and M. longipes A. Milne-Edwards & Bouvier, 1899 is indistinguishable from M. tenuirostris (Leach, 1814), using COI sequences. The respective synonimisations, supported by morphological data, are proposed. M. czernjawskii is a Black Sea – Mediterranean endemic occurring also in the neighbouring Atlantic coastal zone of the Iberian Peninsula and occupying shallower depth, compared to other Mediterranean species of Macropodia. As an upper subtidal inshore species, it is particularly specialised in self-decoration and stimulates abundant epibiosis, providing masking and protection. The bulk of epibiosis consists of algae and cyanobacteria. Amongst the 25 autotrophic eukaryote taxa, identified to the lowest possible level, green chlorophytes Cladophora sp. and calcareous rhodophytes Corallinales gen. sp. were most commonly recorded. Non-indigenous red alga Bonnemaisonia hamifera Hariot, first officially recorded at the Caucasian coast of the Black Sea in 2015, was present in the epibiosis of M. czernjawskii in Crimea as early as 2011.

Revision of the deep-water spider crab genus, Scyramathia A. Milne-Edwards, 1880, with the description of a new species from the Mediterranean and notes on Rochinia A. Milne-Edwards, 1875, and Anamathia Smith, 1885 (Crustacea, Decapoda, Brachyura, Epialtidae) https://zse.pensoft.net/article/48041/ Zoosystematics and Evolution 96(2): 537-569

DOI: 10.3897/zse.96.48041

Authors: Bee Yan Lee, Bertrand Richer De Forges, Peter K. L. Ng

Abstract: The taxonomy of the deep-water spider crabs of the genus Scyramathia A. Milne-Edwards, 1880, is revised and four extant species are recognised from the Atlantic and western Indian Ocean: S. carpenteri (Norman, in Thomson 1873) (type species), S. umbonata (Stimpson, 1871), S. hertwigi Doflein, in Chun 1900, and S. tenuipes sp. nov. Scyramathia tenuipes sp. nov. from the Mediterreanean is easily distinguished from its congeners by its slender and elongate ambulatory legs. All species are diagnosed and figured. The taxonomy of two allied genera from the Atlantic and Mediterranean, Rochinia A. Milne-Edwards, 1875, and Anamathia Smith, 1885, are also treated and their type species redescribed and figured.

A new genus for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836 (Crustacea, Brachyura, Majoidea), based on morphology and molecular data https://zse.pensoft.net/article/50360/ Zoosystematics and Evolution 96(1): 205-216

DOI: 10.3897/zse.96.50360

Authors: Jessica Colavite, Amanda M. Windsor, William Santana

Abstract: A new genus of majoid spider crab, Pohleus gen. nov. is established for Pericera septemspinosa Stimpson, 1871 and Pericera heptacantha Bell, 1836, based on morphology and molecular data from the partial sequences of the 12S and 16S mitochondrial genes and the 18S small subunit rRNA nuclear locus. The species are re-described and illustrated, based on material from several localities of the western Atlantic and eastern Pacific oceans. The carapace, antennal and pterygostomial spines, male thoracic sternum and first gonopods are distinctive characters, distinguishing Pohleus gen. nov. from species assigned to Macrocoeloma Miers, 1879, where P. septemspinosus and P. heptacanthus are currently included.

Establishment of a new shrimp family Chlorotocellidae for four genera previously assigned to Pandalidae (Decapoda, Caridea, Pandaloidea) https://zse.pensoft.net/article/35999/ Zoosystematics and Evolution 95(2): 391-402

DOI: 10.3897/zse.95.35999

Authors: Tomoyuki Komai, Tin-Yam Chan, Sammy De Grave

Abstract: A new caridean shrimp family, Chlorotocellidae, is established to accommodate four genera previously assigned to Pandalidae, viz., Chlorotocella Balss, 1914 (type genus), Chlorocurtis Kemp, 1925, Anachlorocurtis Hayashi, 1975, and Miropandalus Bruce, 1983, which represents the sister clade to a clade consisting of all other pandalid genera (including the two genera previously assigned to Thalassocarididae) in a recent comprehensive phylogenetic analysis of Pandaloidea. Diagnoses are provided for the new family and its constituent genera, and a comparison with Pandalidae is provided, for which a new diagnosis is given.
