This species is characterized by its yellow-brown to brown thallus having areoles 0.4 to 1.5 mm across, branched and anastomosing paraphyses, a tall hymenium, large ascospores 20–32 × 10–16 μm, and no substance detected by thin layer chromatography. All other species of the genus have ascospore dimensions in the range of 14–22 × 5–14 μm. A phylogenetic analysis is provided based on ITS nrDNA sequences, and supports the separation of the novel species. Photographs and a comparative analysis with related species of Lecaimmeria are provided to confirm the status of the species.</p> Kamran Habib, Rizwana Zulfiqar, Abdul Nasir Khalid Copyright (c) 2022 Kamran Habib, Rizwana Zulfiqar, Abdul Nasir Khalid Tue, 16 Aug 2022 01:11:10 -0700 The Paepalanthoideae (Eriocaulaceae) of the Chapada dos Veadeiros National Park, Brazil: taxonomic novelties, identification key, and illustrated list of species <p>The Chapada dos Veadeiros National Park is a conservation unit established to preserve the highest savannahs of Central Brazil and their unique biodiversity. Eriocaulaceae are a relevant and conspicuous family in such high savannahs, but its diversity is poorly known, documented solely in general lists or in isolated efforts aimed at small groups. After a structured series of field expeditions and analysis of specimens from the relevant herbaria, we provide nomenclatural novelties, a first identification key, and an illustrated checklist for the species of Paepalanthoideae (Eriocaulaceae) in the area. We recorded 42 species of Paepalanthoideae from the Chapada dos Veadeiros National Park: <em>Actinocephalus </em>(Körn.) Sano (2 spp.), <em>Comanthera </em>L.B.Sm<em>. </em>(1 sp.), <em>Paepalanthus </em>Mart. (24&nbsp;spp.), and <em>Syngonanthus</em> Ruhland (15 spp.). <em>Actinocephalus brevifolius </em>Trovó &amp;&nbsp;Echtern. sp. nov. and <em>P.&nbsp;irwinii</em> Trovó&nbsp;&amp;&nbsp;Echtern. sp. nov. are newly described species and <em>P.&nbsp;politus</em> Trovó stat. et nom. nov. is a variety of <em>P.&nbsp;elongatus </em>(Bong.) Körn. raised to the species status with a new name. The generic and specific composition shows predominance of <em>Paepalanthus </em>and <em>Syngonanthus</em>, and with a low representation of <em>Actinocephalus </em>and <em>Comanthera</em>, as expected, outside of the Espinhaço Range. More than 50% of the species (22 spp.) are endemic to the area and 25 species are endemic to Central Brazil, the area being the main center of diversity for dimerous-flowered groups. The non-endemic diversity is a combination of widespread species and marginal distribution of species typical from the Amazon and southeastern savannahs. The species are unevenly distributed in the area, with their occurrence correlated to altitude, water availability, and lithology. We reinforce that the savannahs from Central Brazil are a secondary center of diversity for Eriocaulaceae, playing a central role in the conservation of an unique and irreplaceable piece of its diversity and the Cerrado biome as well.</p> Marcelo Trovó, Lívia Echternacht Copyright (c) 2022 Marcelo Trovó, Lívia Echternacht Wed, 10 Aug 2022 00:39:09 -0700 A new species of the genus Cottus (Scorpaeniformes, Cottidae) from the Baltic Sea Basin and its phylogenetic placement <p>The genus <em>Cottus</em> contains more than 60 species that are common in freshwater bodies of northern Eurasia and North America. Despite the abundance of species, this genus has been insufficiently studied in Eastern European rivers and lakes. The new taxon <em>Cottus cyclophthalmus</em> sp. nov. was found in the Neman/Nemunas and Venta river systems (Baltic Sea Basin). <em>Cottus cyclophthalmus</em> is sister and most morphologically similar to <em>Cottus gobio</em>. The new species has the following diagnostic characters: round, protruding (tubular) eyes near front of head; dermal papillae on top and sides of head, naked body, absence of bony prickles, full trunk canal with 32–36 pores. The description of <em>Cottus cyclophthalmus</em> and a new finding of <em>Cottus microstomus</em> improved understanding of the Eastern European biodiversity.</p> Valentina Sideleva, Vytautas Kesminas, Zakhar Zhidkov Copyright (c) 2022 Valentina Sideleva, Vytautas Kesminas, Zakhar Zhidkov Tue, 09 Aug 2022 01:29:02 -0700 A new species of Paranecepsia (Euphorbiaceae-Acalyphoideae) from Madagascar and its relationships among the ‘alchorneoids clade’ <p>The formerly monotypic genus <em>Paranecepsia</em> Radcl.-Sm. is expanded with the description and illustration of a second species, <em>Paranecepsia andrafiabensis</em> Barberá &amp; O.Lachenaud sp. nov. Molecular phylogenetic analyses of plastid<em> rbcL</em> and <em>trnL-F</em> data confirm a sister relationship between the new species and <em>P. alchorneifolia</em> Radcl.-Sm., as members of the alchorneoids clade. <em>Paranecepsia andrafiabensis</em> sp. nov. is notable for expanding the character states for the genus (now including both 2- and 3-locular ovary species) and broadening the geographic range of the genus from continental Africa to Madagascar. The new species adds to the diverse karst limestone endemics of northwestern Madagascar, where it has a very restricted distribution at the base of the western wall of the Ankarana tsingy. An amended generic description of <em>Paranecepsia</em> and a key to the species are also presented.<em> Paranecepsia andrafiabensis</em> sp. nov. is provisionally assessed as VU D1 based on the IUCN Red List criteria.</p> Patricia Barberá, Olivier Lachenaud, Ricarda Riina Copyright (c) 2022 Patricia Barberá, Olivier Lachenaud, Ricarda Riina Mon, 08 Aug 2022 00:00:00 -0700 Two new species of the genus Siro Latreille, 1796 (Opiliones, Cyphophthalmi, Sironidae) in the European fauna <p>Two new opilionid species from suborder Cyphophthalmi, family Sironidae, <em>Siro franzi</em> Karaman &amp; Raspotnig sp. nov. and <em>Siro ozimeci</em> Karaman sp.&nbsp;nov., from Austria and Croatia respectively, are described and illustrated. Both species show a close relation to two other relict sironid species from the southern and eastern parts of the Alps, <em>Siro</em> <em>valleorum </em>and<em> Siro crassus.</em> All four species are treated here as a monophyletic, alpine group of genus <em>Siro</em>, opposed to the remaining two European sironids, <em>S.&nbsp;rubens</em> and <em>S.&nbsp;carpaticus </em>(palaeoeuropean <em>Siro</em> group). The history of the alpine <em>Siro</em> group parallels the history of a part of the dynamic European archipelago in the Mediterranean Tethys area, which became a part of the Alpine orogeny. Diversification of the alpine <em>Siro</em> group is the result of the orogenic evolution of the Alps, linked to the Austroalpine and South Alpine tectonic units.</p> Ivo Karaman, Andrea Lienhard, Kathrin Niklos, Guenther Raspotnig Copyright (c) 2022 Ivo Karaman, Andrea Lienhard, Kathrin Niklos, Guenther Raspotnig Fri, 05 Aug 2022 00:00:00 -0700 Integrating morphology with phylogenomics to describe four island endemic species of Temnothorax from Sicily and Malta (Hymenoptera, Formicidae) <p><em>Temnothorax </em>(Myrmicinae, Crematogastrini) is one of the most diverse Holarctic ant genera, and new taxonomic advancements are still frequent worldwide. The Mediterranean region, a global biodiversity hotspot characterized by a complex geographic history, is home to a substantial portion of its described diversity. Sicily is the region’s largest island and, as ongoing investigations are revealing, it is inhabited by a long-overlooked but highly diverse ant fauna that combines multiple biogeographic influences. We combined qualitative and quantitative morphology of multiple castes with phylogenomic analysis based on ultra-conserved elements (UCEs) to describe four species of <em>Temnothorax </em>endemic to Sicily and the neighboring Maltese Islands (Sicilian Channel). Three of these species, <em>T.&nbsp;marae </em>Alicata, Schifani &amp; Prebus sp. nov., <em>T.&nbsp;poldii </em>Alicata, Schifani &amp; Prebus sp. nov. and <em>T.&nbsp;vivianoi </em>Schifani, Alicata &amp; Prebus sp. nov., are new to science, while a redescription clarifies the identity of <em>T.&nbsp;lagrecai </em>(Baroni Urbani, 1964). These descriptions highlight the current difficulties of delimiting monophyletic <em>Temnothorax </em>species groups based on morphological characters. The intra-insular endemicity patterns we revealed highlight the importance of Mediterranean paleogeography to contemporary ant diversity and distribution in the region.</p> Enrico Schifani, Matthew M.

Diagnoses, illustrations and known distributional data are given. In addition, the generic affinities and subdivision of <em>Myolepta</em> are discussed based on these newly described taxa.</p> Ximo Mengual Copyright (c) 2022 Ximo Mengual Tue, 02 Aug 2022 00:51:44 -0700 Taxonomic implications of describing a new species of Loimia (Annelida, Terebellidae) with two size-dependent morphotypes <p>We describe <em>Loimia davidi</em> sp. nov. (Annelida, Terebellidae) from São Miguel Island (Azores). It resembles <em>Loimia gigantea</em> (Montagu, 1819) (English Channel) in having very large adults, the ventral shield shape and the types of capillary notochaetae (three), while differing in shape and colour of the lateral lappets, branchiae length, the arrangement of segments, ventral shields, uncini and pygidial papillae. Large (&gt; 30 cm long) and small (≈ 5 cm long) specimens of <em>L. davidi</em> sp. nov. show typically interspecific morphological differences while clustering in a single entity after species delimitation analyses of a cytochrome c oxidase I fragment. Therefore, we consider them to belong to a single species and discuss the taxonomic implications of size-dependent morphological differences. Within <em>Loimia</em>, we (1) suggest that large specimens may have been scarcely reported due to their rarity and collecting difficulty, while small specimens may have been reported either as ‘sp.’ or as the ‘cosmopolitan’ <em>Loimia medusa</em> (Savigny, 1822), (2) evaluate the size-related morphological disparity in all described species using a hypervolume analysis, (3) identify possible similar size-dependency in previously described species, (4) summarise the morphological information of all known species of <em>Loimia</em>; and (5) discuss on the four species reported in Europe.</p> Daniel Martin, Maria Capa, Alejandro Martínez, Ana Cristina Costa Copyright (c) 2022 Daniel Martin, Maria Capa, Alejandro Martínez, Ana Cristina Costa Mon, 01 Aug 2022 02:40:59 -0700 Cladoceras rovumense sp. nov. (Gentianales-Rubiaceae), a new species from southeast Tanzania and northeast Mozambique <p class="p1">Following a review of the circumscription of the genus <em>Cladoceras</em> Bremek. (Rubiaceae) in relation to <em>Tarenna </em>Gaertn., the new species <em>Cladoceras rovumense</em> I.Darbysh., J.E.Burrows &amp;#38; Q.Luke sp. nov. is described from the dry forests of the Rovuma Centre of Plant Endemism (CoE) in southeast Tanzania and northeast Mozambique. This species has previously been known as <em>Tarenna</em> sp. 53, following the revision of African <em>Tarenna </em>by Jérôme Degreef. A comparison to <em>Cladoceras subcapitatum </em>(K.Schum. &amp;#38; K.Krause) Bremek., the only other member of this genus as currently circumscribed, is provided. The new species is assessed as Endangered under the criteria of the IUCN Red List. New records for Mozambique of two further Rovuma CoE endemics are recorded: <em>Celosia patentiloba</em> C.C.Towns. (Amaranthaceae) and <em>Cordia fissistyla</em> Vollesen (Boraginaceae), both of which are globally threatened.</p> Iain Darbyshire, John E.
