Diversity and distribution of intertidal Microporella (Bryozoa: Cheilostomatida) from California
(2024)
Seven species of the cheilostome bryozoan genus Microporella were identified across 15 rocky intertidal sites spanning 940 km of the California coast, from Mill Creek in the Montereyan Pacific Transition Region north to Point Saint George in the Mendocinian Region. Colonies of Microporella were found encrusting boulders and mollusc shells. Among these species, three are new to science, namely Microporella dentata Chowdhury & Di Martino sp. nov., M. pauciperforata Chowdhury & Di Martino sp. nov. and M. rota Chowdhury & Di Martino sp. nov. Three other species, M. californica, M. setiformis, and M. umbonata have previously been recorded from other localities in California. Finally, Microporella neocribroides, originally described from off Kodiak Island, Alaska, and subsequently found in Hokkaido, Japan, was recorded in California for the first time. An additional new species, M. similis Chowdhury & Di Martino sp. nov., was identified through the re-examination of museum material previously attributed to M. cribrosa and M. californica. These newly acquired data allowed for a more comprehensive examination of the distribution of species, intraspecific variability, and potential predator-induced teratologies in certain species, thanks to the availability of numerous colonies from various sites and the re-examination of museum records. Altogether, this study increases the known Recent diversity of Microporella in California’s waters to a total of 18 species.
The use of integrative taxonomy has confirmed the existence of a new distinct crab species, cryptic, within the group of the former genus Liocarcinus, now Polybius, closely related to P. holsatus, P. vernalis and P. marmoreus. Previous reports have considered it to be the Atlantic form of P. vernalis, or as a species “affinis” or “comparable to” P. holsatus. Diagnostic morphological characters are presented for identification and the morphological variability in these species, mainly within P. vernalis (the most related) is analysed. Furthermore, based on molecular and other previous data, a new combination (genus change) is proposed. This new species, Polybius dioscurus sp. nov., lives on infralittoral sandy bottoms, coexisting with the other species mentioned, in the temperate and subtropical zone of the North Atlantic Ocean, including the Alboran Sea (westernmost Mediterranean).
In this study, I describe two new species of Macrobiotus based on morphological data collected through light and scanning electron microscopy. Both species are accompanied by DNA sequences from four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). Macrobiotus ovovittatus sp. nov. was discovered in Greenland and can be distinguished from similar taxa of Macrobiotus by its continuous, solid, and clearly wrinkled egg surface, adorned with sparse, very small and irregularly spaced pores. Additionally, the terminal discs of egg processes are covered in multiple light-refracting dots, resembling crocheted napkins. Macrobiotus mileri sp. nov. was found in Israel and is characterized by unique pore arrangements in its body cuticle, expressed in two distinct animal forms: (i) forma porata with large pores arranged in five distinct patches and (ii) forma aporata with single, almost undetectable pores. It also features weakly defined convex terminal discs with smooth edges. Furthermore, the phylogenetic analyses conducted in this study offer the most updated phylogeny of superclade I within the family Macrobiotidae. This facilitates additional discussion concerning the interrelationships among species within the genus Macrobiotus and the circumscription of species groups within it.
Two new species of aulacid wasps, Pristaulacus iuliae Turrisi & Nobile sp. nov. from South India (Karnataka) and Pristaulacus ninae sp. nov. from Peninsular Malaysia (Pahang), are described, figured and compared with most related species. Based on the present addition, the Indomalayan area currently includes 27 species of Pristaulacus Kieffer out of 61 known from the whole Oriental Region, which is however a largely underestimated number. An identification key to species and an updated checklist of Pristaulacus occurring in the Indomalayan area are provided.
The taxa of the subgenus Turritus of Cochlostoma (Cochlostomatidae) are analysed based on molecular and morphological data. The phylogenetic trees, based on ribosomal (16S) and nuclear (H3) DNA, indicate that the currently accepted taxonomy should be revised. Based on our data, there are 37 species in Turritus of which 5 are new to science: Cochlostoma (Turritus) pallgergelyi sp. nov., C. (T. ) muranyii sp. nov., C. (T. ) hallgassi sp. nov., C. (T. ) kontschani sp. nov. and C. (T. ) lacazei sp. nov. Of these, we describe the shells and the female genitalia and summarize the distributional data. Some samples (or set of samples) will remain undetermined for lack of data and these are reported in the appendix.
Empty shells (thanatocoenoses) have been reviewed of species in the genus Granulina (Gastropoda: Granulinidae) from the lower shelf and upper bathyal zones off Mauritania and Western Sahara. We encountered nine species of which four were already known from off Mauritania. Four new species are proposed herein: Granulina reginae sp. nov., G. ronaldi sp. nov., G. sandrae sp. nov. and G. sigridae sp. nov. These four sympatric new species lack labial denticles and they probably form a phyletic clade with a common ancestor. Most hitherto known species in Granulina from the NE Atlantic Ocean and the Mediterranean possess labial denticles. One additional new species with denticles was left in open nomenclature because the material available was considered inadequate. Species in Granulina from Mauritania and Western Sahara have not been found off NW Morocco or the Canary Islands, and the species known from NW Morocco and the Canary Islands have not been found off Mauritania and Western Sahara. The southern extents of the distributions of the Mauritanian species are currently uncertain as additional sampling would be required off Senegal or further South. A key to Mauritanian species in Granulina is given.
The genus Armillipora Quate is recorded for the first time in Ecuador, with a new geographical record for Armillipora selvica Quate, 1996 and the descriptions of two new species, namely Armillipora muyu sp. nov. and Armillipora imitata sp. nov., doubling the total number of species in the genus. In addition, we make available the first DNA barcodes for the genus, providing a sequence of the 5´-end of the cytochrome c oxidase subunit I (COI) gene for A. imitata, A. muyu, and, A. selvica. Moreover, we describe the second known female of the genus and we provide a taxonomical key for the known males of the world. Finally, we build Species Distribution Models and discuss the potential distribution of the genus in the Neotropical region.

The vetigastropod material collected on Walters Shoal during Cruise MD208 of the Tropical Deep-Sea Benthos programme is documented. In total, 50 species were obtained, 30 of which are new and apparently endemic to the seamount. Of the other 20 species, eight are regionally endemic to the south-western Indian Ocean, 11 are more widely distributed in the Indo-West Pacific and one is possibly of deep-water Atlantic origin. The primary affinities of the fauna are with warm temperate South Africa and the tropical western Indian Ocean, but one species is potentially a seamount endemic of southern affinity. A new pseudococculinid genus living on decomposing bird feathers is described, a biogenic substrate association previously unknown in the Mollusca. The following new genera are described: Imbricoscelis gen. nov. and Pterodacna gen. nov. The following new species are described: Akritogyra crenulata sp. nov., Bathymophila williamsae sp. nov., Benthobrookula araneum sp. nov., Be. galeneae sp. nov., Be. laticostata sp. nov., Be. scalaroides sp. nov., Be. semisculpta sp. nov., Bruceina areneformis sp. nov., Calliostoma pantopunctatum sp. nov., Cantrainea herosae sp. nov., Carinastele achrosta sp. nov., Cornisepta marshalli sp. nov., Emarginula lentiginosa sp. nov., E. nodulicostata sp. nov., E. retrogyra sp. nov., E. salebrosa sp. nov., Fluxinella dufresneae sp. nov., Gibbula roseosticta sp. nov., Hadroconus scobina sp. nov., Kaiparathina monticola sp. nov., Lissotesta wareni sp. nov., Microcollonia miniata sp. nov., Mikro crassus sp. nov., Parviturbo cicatricosus sp. nov., Phragmomphalina candida sp. nov., Pterodacna boucheti gen. et sp. nov., Solariella asaphea sp. nov., Spinicalliotropis lepidota sp. nov., Stomatella multilirata sp. nov. and Trenchia mcleani sp. nov. The following new combinations are proposed: Brookula coronis Barnard, 1963 is transferred to Imbricoscelis gen. nov., Cantharidus nolfi Poppe, Tagaro & H. Dekker, 2006 is transferred to Kaiparathina Laws, 1941 and Solariella incisura Melvill, 1909 is transferred to Phragmomphalina Herbert & Williams, 2020. The following new synonyms are proposed: Carinastele wareni Vilvens, 2014 is a synonym of Bruceina cognata (Marshall, 1988); Fluxinella stellaris Bozzetti, 2008 is a synonym of Agagus stellamaris Herbert, 1991.
The “trachystreptoform” species of Spirostreptidae, i.e., species which would formerly have been ascribed to the tribe Trachystreptini, from the Udzungwa Mountains are (re)described, including one new genus and five new species: Attemsostreptus reflexus Akkari & Enghoff, 2019, A. cataractae Enghoff sp. nov., A. leptoptilos Enghoff sp. nov., A. julostriatus Enghoff sp. nov., Lophostreptus tersus (Cook, 1896) (= L. ptilostreptoides Carl, 1909 syn. nov.), L. magombera Enghoff sp. nov., and Udzungwastreptus marianae Enghoff gen. et sp. nov. The type material of Lophostreptus regularis Attems, 1909 (= L. tersus) is discussed. The discussion includes paragraphs on the classification and the Udzungwa fauna of Spirostreptidae, on grouping of the Udzungwa trachystreptoform species in relation to altitude, and on the possibly recent immigration of A. reflexus and L. tersus into the Udzungwa Mts.
Known by many names, the Chinese banyan (Ficus microcarpa L.) is a monoecious plant species originating from south-eastern Asia which has been introduced as an ornamental in numerous areas outside its native range, including the Mediterranean. Like every species of Ficus, it is associated with a series of chalcid wasp species, known as fig wasps. These species are distributed in the families Agaonidae, Epichrysomallidae, Eurytomidae, Ormyridae and Pteromalidae. In this publication, we describe a new species of Ormyrus Westwood, 1832 (Hymenoptera, Chalcidoidea, Ormyridae), O. microcarpae Askew & Koutsoukos sp. nov., reared from figs of F. microcarpa collected from Greece and Cyprus. The new species is compared with O. lini and O. watshami. This species is likely to be a parasitoid of Meselatus bicolor Chen, 1999 (Hymenoptera, Epichrysomallidae). In addition, the previously unknown female of O. lini is also described and illustrated. This publication constitutes the first report of species of Ormyrus associated with figs in Europe.

Zhang sp. nov. (♂♀), S. simianshan Wang, Lu & Z.S. Zhang sp. nov. (♂♀) and S. yintiaoling Wang, Lu & Z.S. Zhang sp. nov. (♂). Females of S. aviforma Jin & Zhang, 2020 (♂♀) and S. quadrata Jin & Zhang, 2020 (♂♀) are described for the first time. Photos of the body and copulatory organs, as well as the locality map are provided.
A new species Alainites neeru sp. nov. is described based on larvae collected from a hill stream in Jammu and Kashmir, India. It is the first report of the genus Alainites Waltz & McCafferty, 1994 from India. The new species is closely related to the Palearctic species A. muticus (Linnaeus, 1758), but can be distinguished from the latter by the length of the maxillary palp, the reduced number of spine-like setae on the margin between the prostheca and mola of the right mandible, the reduced tracheation in the tergalii, and by a reduced number of spines on the prolongation of the paraproct. With this record, the genus Alainites encompasses a total of twenty-two species.
Serratichneumon Riedel & Sheng gen. nov. and Serratichneumon maculatus Sheng & Riedel gen. et sp. nov. belonging to the tribe Ichneumonini of subfamily Ichneumoninae (Hymenoptera: Ichneumonidae), collected in the Oriental Region (China, Vietnam, and Indonesia), are described and illustrated. The new genus is placed in Tereshkin’s key to the Palaearctic genera of the subtribe Amblytelina, and compared with similar genera, Hepiopelmus Wesmael, 1845, and Tricholabus Thomson, 1894.
The nitidus species group of the bee genus Scrapter Lepeletier & Serville, 1828 is redefi ned, revised and 15 species are described as new for science: S.caeruleus sp. nov. ♀, S.confusus sp. nov. ♀♂, S.convexoides sp. nov. ♂, S. convexus sp. nov. ♀♂, S. crassipunctatus sp. nov. ♀♂, S.felicis sp. nov. ♀♂, S.fl avipunctatus sp. nov. ♀♂, S.imparilis sp. nov. ♀♂, S. littoralis sp. nov. ♀, S.longicornis sp. nov. ♂, S.montanus sp. nov. ♀♂, S.mpumalangensis sp. nov. ♀♂, S.obtusus sp. nov. ♀♂, S. perpunctatulus sp. nov. ♂ and S.variabilis sp. nov. ♀♂. The previously unknown males of S. divergens (Friese, 1925), S. semirufus Cockerell, 1932 and S. perpunctatus Cockerell, 1933 are described for the fi rst time. All currently known 28 species of the S. nitidus species group are redescribed, imaged and included in a key to facilitate their identifi cation.
Four new species of Alloxysta (Hym.: Cynipoidea: Figitidae: Charipinae) from Petr Starý’s collection
(2023)
After the revision of Petr Starý’s Charipinae collection, four new species of Alloxysta Förster, 1869 have been found. This collection represents a good overview of the Charipinae fauna worldwide, although the best represented area is Central Europe. Here, we describe four new species of Alloxysta: A. llumae Ferrer-Suay sp. nov., A. onae Ferrer-Suay sp. nov., A. poli Ferrer-Suay sp. nov. and A. staryi Ferrer-Suay & Pujade-Villar sp. nov. Three of these new species are based on reared specimens. Diagnosis, distribution, and description of the new species are given and illustrated.
A review of the genus Stratiomys from India is presented. The new species Stratiomys brunettii sp. nov. is described based on male and female specimens collected from the Kashmir Himalayas. The only other congener previously recorded in India, Stratiomys approximata, is redescribed. A key to the species is presented.
The Australian genus Pleuroseta Richards, 1973 is revised, including P. wentworthi (Richards, 1973) and three new species: P. ingens sp. nov. (Queensland), P. monteithi sp. nov. (Queensland) and P. occidentalis sp. nov. (Western Australia). Leptocera (Biroina) dorrigonis Richards, 1973 is treated as a new junior synonym of Pleuroseta wentworthi.
A faunal study for the order Phasmatodea of the Chicaque Natural Park is presented, including a list of species found, descriptions, redescriptions, and biological notes. A total of nine species were found and studied; two new genera: Ramandeun new genus, Nubilophasma new genus, and four new species: Atratomorpha jorgei new species, Isagoras franciscoverai new species, Nubilophasma chicaquensis new genus and new species, and Ramandeum coronatum new genus and new species are described. The description of the eggs of the new taxa, of the previously unknown eggs of Paraceroys quadrispinosus (Redtenbacher, 1906), and the redescription of the eggs of Libethra rabdota Stål, 1875, and Libethra inchoata Brunner von Wattenwyl, 1907 are provided. Additional comments on the ecology and morphological variation of the reviewed taxa are included. Finally, further studies on the stick insect fauna of the Colombian Andes are discussed and recommended to provide more information to broaden the understanding of the species that inhabit this complex mountain system.
