Several species of <em>Zingiber</em> are cultivated globally for their medicinal and culinary value, such as true gingers (<em>Z.&nbsp;officinale</em>), bitter gingers (<em>Z.&nbsp;zerumbet</em>), and <em>Z.&nbsp;purpureum</em>. In Taiwan, two endemic species and one incompletely known taxon were recorded in the last edition of Flora of Taiwan, and several taxonomic issues still remain unresolved. Therefore, we revised the Taiwanese <em>Zingiber</em> based on morphological, palynological, anatomical, and molecular evidence, as well as their distribution. The results showed that floral characters such as labellum, fertile bracts, and corolla tubes are of great taxonomic value in distinguishing taxa of <em>Zingiber</em> of Taiwan. Accordingly, five species are treated in the present study, namely <em>Z.&nbsp;chengii</em> Y.H.Tseng, C.M.Wang &amp; Y.C.Lin, <em>Z.&nbsp;mioga</em> Thunb., <em>Z.&nbsp;oligophyllum</em> K.Schum., <em>Z.&nbsp;pleiostachyum</em> K.Schum., and <em>Z.&nbsp;shuanglongense</em> C.L.Yeh &amp; S.W.Chung. <em>Zingiber mioga</em> might be a newly naturalized species to Taiwan. <em>Zingiber kawagoii</em> Hayata and <em>Z.&nbsp;koshunense</em> C.T.Moo are treated as synonyms of <em>Z.&nbsp;pleiostachyum</em>.</p> Yuan-Chien Lin Chien-Ti Chao Chih-Yi Chang Yen-Hsueh Tseng Copyright (c) 2022 Yuan-Chien Lin, Chien-Ti Chao, Chih-Yi Chang, Yen-Hsueh Tseng 2022-09-28 2022-09-28 839 74 102 10.5852/ejt.2022.839.1933 Revision of the genus Dicranopalpus from northern Spain and Corsica, with descriptions of two new species (Arachnida, Opiliones, Phalangioidea) <p>The Iberian Peninsula represents a diversity hotspot for the genus <em>Dicranopalpus</em>. However, most taxa are insufficiently defined. Our revision of the <em>Dicranopalpus pyrenaeus</em> species group reveals two hidden species:<em> D. catariegensis</em> sp. nov. and <em>D. gallaecicus</em> sp. nov. Two species, <em>D.&nbsp;pyrenaeus </em>from the Spanish and French Pyrenees and <em>D. insignipalpis</em> from Corsica, are redescribed. <em>Dicranopalpus cantabricus</em> Dresco, 1953 is resurrected as a valid species. Three new synonyms of <em>D.&nbsp;martini</em> (Simon, 1878) are proposed: <em>Fagea bolivari</em> Dresco, 1949 (including <em>D. bolivari</em> sensu Rambla 1975), <em>Egaenasser extraordinarius</em> Roewer, 1953 and <em>Dicranopalpus dispar</em> Rambla, 1967. With these additions, the Iberian Peninsula harbours four species of the <em>Dicranopalpus pyrenaeus</em> species group. They largely have allopatric distributions, ranging from the Pyrenees and the Cantabrian mountain range to the west coast of Galicia.</p> Hay Wijnhoven Jochen Martens Carlos E.

After the analysis of these collections, we concluded that they represent a new species, <em>C.&nbsp;sertanejus</em> Sodré &amp; M.J.Silva sp. nov., which was also corroborated by an anatomical study of their leaves. This new species can be differentiated by pseudomonopodial branching, leaves with petioles up to 1.7 cm long, 4–6 subsessile nectary glands and indumentum of sessile trichomes on both surfaces. Detailed descriptions, including details of leaf anatomy, are provided for <em>C.&nbsp;sertanejus</em> sp.&nbsp;nov. and <em>C.&nbsp;echioides</em>, its closely related species. We also formalize the synonymization of <em>C.&nbsp;kalkmannii</em> under <em>C.&nbsp;echioides</em> and re-evaluate the typification of these names, in order to better clarify their taxonomic status.</p> Rodolfo Carneiro Sodré Marcos José da Silva Copyright (c) 2022 Rodolfo Carneiro Sodré, Marcos José da Silva 2022-09-22 2022-09-22 839 14 38 10.5852/ejt.2022.839.1929 Two species of Dolichomitus Smith, 1877 (Hymenoptera, Ichneumonidae, Pimplinae) parasitizing borers of Juglans mandshurica Maxim. and a key to species known from China <p>Two species of <em>Dolichomitus</em> Smith, 1877 emerged from the trunks of <em>Juglans mandshurica</em> Maxim. in Kuandian and Benxi Manzu Autonomous Counties, Liaoning, in the Palaearctic part of China.

In total, 130 ant species are now known from Oman, including 53&nbsp;from Dhofar. The known ants of Dhofar are primarily of Afrotropical origin (23 species, 43%), followed by Palearctic (20 species, 38%), and Indomalayan (4&nbsp;species, 8%), and a single species from both the Malagasy and Neotropical Regions (1%). Five species (9%) are apparently endemic to Dhofar, <em>Lepisiota dhofara </em>Collingwood &amp; Agosti, 1996, <em>Lepisiota elbazi</em> Sharaf &amp; Hita Garcia, 2020, <em>Crematogaster jacindae </em>Sharaf &amp; Hita Garcia, 2019, <em>Meranoplus mosalahi </em>Sharaf, 2019, and <em>Nesomyrmex micheleae </em>Sharaf, 2020. The zoogeography of the Omani ant fauna reflects a clear dominance of faunal elements from the Palearctic Region (68 species, 53%) followed by Afrotropical faunal elements (45 species, 34%), and five species that are broadly spread throughout both the Palearctic and the Afrotropical Regions (4%). There are nine species (6%) from the Indomalayan Region, two species from the Neotropical Region (2%), <em>T. melanocephalum</em>, <em>C.&nbsp;emeryi</em>, and a single species <em>Ph. megacephala</em> (1%) from the Malagasy Region. The number of endemic species (15 species, 12%) is relatively low compared to the large geographical area of Oman and the broad diversity of habitats that characterizes the country.</p> Mostafa R.

Molecular phylogenetic analyses (nuclear <em>28S</em> and mitochondrial <em>mtMutS</em>) resolved New Zealand taxa as more closely related to other genera and nominal <em>Alcyonium</em> Linnaeus, 1758 from South America than to the genus’ North Atlantic type species. Due to low genetic variation, species delimitation relied predominantly on identifying consistent differences in sclerite and colony morphology. The former <em>A. aurantiacum</em> is reassigned to <em>Kotatea</em> gen. nov. as <em>K. aurantiaca</em> gen. et comb. nov. and seven new species are described in this genus (<em>K. amicispongia</em> gen. et sp. nov., <em>K. lobata</em> gen. et sp. nov., <em>K. kapotaiora</em> gen. et sp. nov., <em>K. kurakootingotingo</em> gen. et sp. nov., <em>K. niwa</em> gen. et sp. nov., <em>K. raekura</em> gen. et sp. nov., and <em>K. teorowai</em> gen. et sp. nov.). Three new species in <em>Ushanaia</em> gen. nov. are also described (<em>U. ferruginea</em> gen. et sp. nov., <em>U. fervens</em> gen. et sp. nov. and <em>U. solida gen. et sp. nov. </em>). These descriptions increase our understanding of New Zealand’s endemic octocoral diversity and contribute to ongoing systematic revisions of <em>Alcyonium</em>.</p> Gustav M.

We used one mitochondrial (COI) and two nuclear markers (18S and 28S) as well as comparative morphological analysis to redefine <em>Lebertia porosa</em>, and to further investigate the species boundaries of Norwegian populations of its close relatives. Our results show that <em>Lebertia porosa</em>, as currently defined, consists of multiple species that can be separated by molecular and morphological characteristics. Although we document the presence of the endosymbiotic bacteria <em>Wolbachia </em>in two out of eight screened genetic lineages, we find no evidence of intraspecific genetic divergence caused by <em>Wolbachia </em>infections. The assignment of one of the genetic lineages to the nominal species could be made through morphological comparisons of specimens from the <em>L. porosa </em>type locality with the syntypes of <em>L. obscura </em>Thor, 1900. Thus, the diagnosis of <em>L. porosa </em>is emended and a neotype is defined. Two of the remaining genetic lineages could be assigned to existing names previously regarded as junior synonyms of <em>L. porosa</em>, namely <em>L. obscura </em>(lectotype defined here) and <em>L. gibbosa </em>Lundblad, 1926, which are both redescribed. The outstanding genetic lineages are unnamed, but from our work we conclude that the taxa <em>Lebertia porosa britannica </em>Thor, 1906, <em>L. porosa dorsalis </em>Thor, 1906, and <em>L. porosa italica </em>Thor, 1906 are nomina dubia that cannot be considered junior synonyms of <em>L. porosa </em>as proposed by K. Viets (1956). We also consider <em>L. vigintimaculata </em>Thor, 1900 a nomen dubium, probably identical to <em>L. obscura</em>.</p> Valentina Tyukosova Reinhard Gerecke Elisabeth Stur Torbjørn Ekrem Copyright (c) 2022 Valentina Tyukosova, Reinhard Gerecke, Elisabeth Stur, Torbjørn Ekrem 2022-09-09 2022-09-09 839 131 169 10.5852/ejt.2022.836.1921 Anurans (Amphibia: Anura) of the Brazilian state of Amapá, eastern Amazonia: species diversity and knowledge gaps <p>We herein present the first annotated anuran checklist for the Brazilian state of Amapá, eastern Amazonia, based on a thorough literature review. We recorded the occurrence of 111 species belonging to 13 anuran families distributed across 48 localities throughout Amapá, within two biomes. Among these species, 62.5% occur exclusively in the Tropical Moist Broadleaf Forest biome, ~8% occur exclusively in the Tropical Savanna biome, and ~29% occur in both. Two species were considered endemic to Amapá and were registered only in the central portion of the state. Regarding the conservation status, only one species (<em>Dendropsophus amicorum</em>) is classified as threatened, assigned to the “critically endangered” category. The other species are categorized as either “least concern” or “data deficient” (85 and 8, respectively), whereas 21 are not evaluated. The current annotated list contributes to the incipient knowledge on anuran species richness in Amapá and, despite the research regarding anuran taxonomy has considerably progressed over the past 20 years, there is still much to do. Our data highlight the need for trained taxonomists to develop research in the state.</p> Pedro P.G. Taucce Carlos Eduardo Costa-Campos Thiago R.
