The genus Tekellina Levi, 1957 is currently composed of ten species, six of which are Neotropical. They are small-sized spiders (0.9 to 1.5 mm), with a wide distribution, with a great diversity in the Neotropical Region and well represented in Brazil. In this article, males and females of the species Tekellina bella Marques & Buckup, 1993 and T. crica Marques & Buckup, 1993 are redescribed and illustrated. The female of Tekellina minor Marques & Buckup, 1993 is described and illustrated for the first time. New records are included for Neotropical species. Tekellina guaiba Marques & Buckup, 1993 is synonymized with T. pretiosa Marques & Buckup, 1993. Three new species are described for Brazil: Tekellina picurrucha Rodrigues & Estol sp. nov. (São Paulo, Paraná and Rio Grande do Sul), Tekellina miuda Rodrigues & Estol sp. nov. (São Paulo and Paraná) and Tekellina miudinha Rodrigues & Estol sp. nov. (São Paulo). Distribution maps with new records and an identification key of the Neotropical species are also presented.
The nine genera of Malagasy spittlebug are revised, with the addition of new characters, facilitating the identification of the species. Nesaulax Jacobi, 1917, is synonymized with Amberana Distant, 1908, leading to a new combination for Amberana vittipennis (Bergroth, 1894). A new endemic genus Soulierana Bucher & Bouteille gen. nov. is proposed for two species originally placed in Literna Stål, 1866, based on morphological characters of the head, tegmina and male genitalia. Also, three new species are described in this genus: Soulierana bigidea Bucher gen. et sp. nov., Soulierana claudinae Bouteille gen. et sp. nov. and Soulierana kelymena Le Cesne gen. et sp. nov. Pictures of species and drawings of the male genitalia for all genera, with the exception of Rhinaulax Amyot & Serville, 1843, Alluaudensia Lallemand, 1920 and Literna, are included. An identification key is available in both a dichotomous format and an interactive format (Xper3).
Twenty-one species of Mysidae were sampled by three ANDEEP expeditions to the Southern Ocean with epibenthic sledges dragged over the deep-sea floor in the realm of 58–71° S and 00–65° W, depth 774–5190 m. Previously known ranges are significantly extended southward for four species and to greater depth in the same four species plus two other species. Supplementary descriptions are given for Amblyops tattersalli and Dactylamblyops murrayi, and a first description of a (subadult) male for Thalassomysis tattersalli. The definitions of the genera Amphiakrops gen. nov., Chelamblyops gen. nov., Desmocornea gen. nov. and Schizurakrops gen. nov. are mainly based on the structure of the eyes as well as of the antennal peduncle, chelate second thoracic endopod and telson. These structures are also important for the descriptions of Amblyops arianii sp. nov., A. bipapillatus sp. nov., Amblyopsoides fenestragothica sp. nov., A. lepidophthalma sp. nov., Amphiakrops brandtae gen. et sp. nov., Dactylamblyops benthophilus sp. nov., Desmocornea subchelata gen. et sp. nov., Paramblyops petrescui sp. nov., Schizurakrops meesi gen. et sp. nov., Scolamblyops muehlenhardtae sp. nov., Stellamblyops doryphorus sp. nov. and Mysidella antarctica sp. nov. Six previously described taxa are recombined as Amblyopsoides laticauda comb. nov., Amphiakrops bidigitatus comb. nov., A. japonicus comb. nov., Chelamblyops globorostris comb. nov., Meierythrops tattersalli comb. nov. and M. triangulatus comb. nov. One species is revised back to the initial combination as Dactylamblyops japonicus. All except one (Mysidella antarctica sp. nov.) newly described (12), newly recombined (6) or back-combined (1) species belong to the Erythropinae. Keys to the resulting 61 genera and 263 species of Erythropinae and 18 species of Mysidellinae are given at the world-wide scale. Ocular papillae with a terminal pore (sensory pore organ) are recorded in nine ANDEEP species. The organ of Bellonci is identified on the reduced eyes in 16 species, among which D. subchelata gen. et sp. nov. has many ommatidia arranged in a self-contained ribbon which shows a banded rhabdom only in non-adults. Reduction of visual elements together with shrinking of ocular papillae during ontogenetic development suggest that non-adults of D. subchelata and T. tattersalli stay in the photic zone for feeding and growth and then descend only once during their lifetime to the abyss for reproduction.
The Chinese members of the genera Leptothorax Mayr, 1855 and Temnothorax Mayr, 1861 are reviewed based on the morphological characters of the worker caste, and 66 species are recognized in China to date. A new synonym is proposed: T. opaciabdomin (Chang & He, 2001) is a junior synonym of T. mongolicus (Pisarski, 1969). Twenty-eight new species of Temnothorax, T. bailu sp. nov., T. chun sp. nov., T. chunfen sp. nov., T. chushu sp. nov., T. dahan sp. nov., T. dashu sp. nov., T. daxue sp. nov., T. dong sp. nov., T. dongzhi sp. nov., T. guyu sp. nov., T. hanlu sp. nov., T. jingzhe sp. nov., T. lichun sp. nov., T. lidong sp. nov., T. liqiu sp. nov., T. lixia sp. nov., T. mangzhong sp. nov., T. qingming sp. nov., T. qiu sp. nov., T. qiufen sp. nov.,T. shuangjiang sp. nov., T. xia sp. nov., T. xiaohan sp. nov., T. xiaoman sp. nov., T. xiaoshu sp. nov., T. xiaoxue sp. nov., T. xiazhi sp. nov., T. yushui sp. nov., are described from China based on worker caste. Three species of Temnothorax, T. desioi (Menozzi, 1939), T. susamyri (Dlussky, 1965) and T. volgensis (Ruzsky, 1905) are recorded in China for the first time. The following eight species are recorded in a province or autonomous region of China for the first time: Leptothorax acervorum (Fabricius, 1793) is a new record in Qinghai, Sichuan and Yunnan; Temnothorax angulohumerus Zhou et al., 2010 is a new record in Guizhou and Tibet; T. argentipes (Wheeler, 1928) is a new record in Sichuan and Yunnan; T. mongolicus (Pisarski, 1969) is a new record in Inner Mongolia; T. reticulatus (Chang & He, 2001) is a new record in Beijing, Gansu, Inner Mongolia, Jilin, Shaanxi and Yunnan; T. spinosior (Forel, 1901) is a new record in Yunnan; T. taivanensis (Wheeler, 1929) is a new record in Guizhou, Sichuan and Yunnan; and T. zhejiangensis Zhou et al., 2010 is a new record in Henan and Guangxi. A key based on the worker caste is provided for the 66 known Chinese species.
Research on the Heteroptera fauna of Turkey has not been extensive enough to illustrate its true diversity. Although several factors contribute to this, the lack of an up-to-date and comprehensive review is a basic factor. To address this issue, we compiled a list of all the Heteroptera species recorded from Turkey in the literature and iNaturalist. In addition, we re-examined several specimens preserved in the Lodos Entomological Museum, İzmir, Turkey (LEMT). Consequently, we excluded 24 species from the checklist of Heteroptera fauna of Turkey, and proposed a new synonymy: Psallus (Psallus) pardalis Seidenstücker, 1966 = Psallus (Psallus) oenderi Wagner, 1976 syn. nov. Furthermore, we recorded following six species from Turkey for the first time: Blissus hirtulus Burmeister, 1835 (Blissidae), Loricula (Loricula) pselaphiformis Curtis, 1833 (Microphysidae), Globiceps (Globiceps) coryli V.G. Putshkov, 1970, Heterocordylus (Heterocordylus) cytisi Josifov, 1958, Mesopsallus fagi (Drapolyuk, 1990) and Psallus (Psallus) helenae Josifov, 1969 (Miridae); and described following six species as new for science: Orthonotus efei Çerçi & Koçak sp. nov., Orthotylus (Parapachylops) oenderi Çerçi, Tezcan & Koçak sp. nov., Orthotylus (Pinocapsus) girayi Çerçi & Tezcan sp. nov., Psallus (Psallus) eceae Çerçi & Koçak sp. nov., Psallus (Psallus) pehlivani Çerçi & Tezcan sp. nov. and Ribautocapsus tezcani Çerçi sp. nov. Altogether, 1668 species of Heteroptera have been recorded from Turkey (664 species in the European part and 1633 species in the Anatolian part) until now, out of them, the presence of 37 species needs confirmation. We determined the chorotypical composition of species as follows: Mediterranean (399 spp., 23.9%), European (380 spp., 22.8%), Local (280 spp., 16.8%), Widespread (182 spp., 10.9%), Endemic (128 spp., 7.7%), Turanian (127 spp., 7.5%), Turano-Mediterranean (89 spp., 5.3%), Europeo-Mediterranean (68 spp., 4.1%) and Alien (12 spp., 0.7%). We showed that provinces in the Eastern Anatolian, Southeastern Anatolian, and Black Sea regions had lower numbers of species recorded, compared to the provinces in the remaining regions. Finally, we underlined that 109 species, absent from Turkey, were recorded from three or more neighboring countries of Turkey. In summary, our findings emphasize that despite the abundant research devoted over the last 150 years to the Heteroptera fauna of Turkey, our understanding of it remains incomplete in the majority, if not in all, of the regions. Our findings strongly encourage further research, particularly in regions with small numbers of recorded species. This endeavor will undoubtedly lead to numerous novel discoveries and provide a better understanding of the true Heteroptera diversity in Turkey.
Five new species of the genus Phlugiolopsis Zeuner, 1940 (Tettigoniidae: Meconematinae) from China
(2024)
This paper reports five new species of Phlugiolopsis Zeuner, 1940 from Sichuan, Yunnan and Guangxi in China, i.e., Phlugiolopsis luojishanensis sp. nov., Phlugiolopsis lata sp. nov., Phlugiolopsis rongshuiensis sp. nov., Phlugiolopsis acuta sp. nov. and Phlugiolopsis daweishanensis sp. nov. We present a redescription of the male of Phlugiolopsis punctata Wang, Li & Liu, 2012, describe the female of Phlugiolopsis punctata Wang, Li & Liu, 2012 and the male of Phlugiolopsis pentagonis Bian, Shi & Chang, 2013 for the first time. In addition, images illustrating the morphology of these species and seven previously described species are provided. The distribution map of the genus Phlugiolopsis from China is also provided.
Two new species, Habrocestum sahyadri sp. nov., and Irura shendurney sp. nov. are described from the Shendurney Wildlife Sanctuary, Kerala. The unknown female of Habrocestum kerala Asima, Caleb, Babu #38; Prasad, 2022 is described and three other species: Gelotia lanka Wijesinghe, 1991, Phintella accentifera (Simon, 1901) and Vailimia jharbari Basumatary, Caleb #38; Das, 2020 are recorded from the locality. Detailed descriptions, diagnosis and illustrations of the species are provided.
Due to the fragility of the ophiuroid (brittle star) skeleton, the bulk of the group’s fossil record consists of dissociated ossicles preserved as microfossils. In spite of their great potential as basis for taxonomic and phylogenetic studies, however, ophiuroid ossicles from the Paleozoic have received very little attention so far. Here, we provide an exhaustive taxonomic assessment of such fossils retrieved from sieving residues from the Silurian of Gotland, Sweden. This material was used in a previous study to describe two key taxa that allowed constraining the origin of the extant ophiuroid clade. The remaining taxa belonging to that same lineage are described in the present paper. The evidence at hand suggests that the stem of the extant ophiuroid clade was formed by two genera, Ophiopetagno and Ophiolofsson gen. nov., including six and five species, respectively, and spanning at least the upper Llandovery through upper Ludlow. We conclude that Ophiopetagno and Ophiolofsson represent sister genera that coexisted through most of the Silurian in the shallow tropical seas of Gotland. They underwent repeated body size reductions in correlation with environmental perturbations, with Ophiopetagno paicei eventually giving rise to Muldaster haakei; the first member of the living Ophiuroidea. Herein, we also introduce two new clades, Ankhurida clade nov. and Ophiovalida clade nov., and the following eight new species: Ophiolofsson joelmciveri gen. et sp. nov., O. obituary gen. et sp. nov., O. immolation gen. et sp. nov., O. archspire gen. et sp. nov., O. hendersonorum gen. et sp. nov., Ophiopetagno bonzo sp. nov., O. kansas sp. nov., O. doro sp. nov.; and two probably new species in open nomenclature: Ophiopetagno sp. 1, and Ophiopetagno sp. 2.
The Indian species of the genera Orionis Shaw and Stenothremma Shaw (Braconidae, Euphorinae) are reviewed. Both genera are reported for the first time from India. Three new species, Orionis shillongensis Gupta, van Achterberg & Pattar sp. nov. from north-eastern India (Meghalaya), O. femorator Gupta, van Achterberg & Pattar sp. nov. from southern India (Karnataka and Tamil Nadu) and Stenothremma flavator Gupta & van Achterberg sp. nov. from southern India (Karnataka) are illustrated and described. A key to the Old World species of Orionis Shaw is provided.
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.
