    Maesa brevipedicellata (Primulaceae), a new species from Papua New Guinea (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 83-85
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Maesa brevipedicellata, a new species of Maesa (Primulaceae-Maesoideae) from Papua New Guinea, \nis described and illustrated based on herbarium specimen observations. The collections of this species resemble \nM. rufovillosa and were previously determined as that species. Maesa brevipedicellata is unique with its selfsupporting habit, hispid hairs throughout and paniculate inflorescences with very short pedicels. This new species \nmainly differs from M. rufovillosa by the habit (tree/shrub in M. brevipedicellata vs climber in M. rufovillosa) and the \ninflorescence structure (panicles in M. brevipedicellata vs simple racemes in M. rufovillosa).

    Three new combinations in Villaria (Octotropideae, Rubiaceae), an endemic genus from the Philippines (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 86-89
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Three new species combinations are made under Villaria for the Philippine endemics Hypobathrum \ncoriaceum, H. multibracteatum and H. purpureum. Morphological features of these three Hypobathrum species \nrevealed a closer resemblance with Villaria than with Hypobathrum, as the three Philippine endemics possess a \nunilocular ovary with parietal placentation; a character that is not found in any genera of Octotropideae except in \nVillaria. Lectotypes and a neotype are selected.

    Hibiscus fabiana sp. nov. (Malvaceae) from the Guinea Highlands (West Africa) (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 69-74
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Hibiscus fabiana Cheek (sect. Furcaria, Malvaceae) is described from the Guinea Highlands of West \nAfrica, and its taxonomic affinities and ecology are considered. Hibiscus fabiana has previously been confused \nwith H. rostellatus but has red fleshy calyx ribs (vs not red and non-fleshy), the calyx surface is glabrous apart from \n1-armed bristles (vs densely covered in minute white stellate hairs and bristles 2\xe2\x80\x935-armed), the leaves 3(\xe2\x80\x935)-lobed, \nbases truncate to rounded (vs 5-lobed, cordate). The conservation status of the new species is assessed using the \nIUCN 2012 standard as Vulnerable. In the context of the recently discovered extinction of the Guinean endemic \nInversodicraea pygmaea G.Taylor (Podostemaceae), we discuss the 30 new species to science discovered in Guinea \nsince 2005, all but one of which are also range-restricted and threatened, usually by development or habitat loss. We \nconsider it urgent to avoid their extinction, ideally with in situ conservation using an Important PlantAreas approach.

    On the morphological variation of Rafflesia cantleyi (Rafflesiaceae) on Pulau Tioman, Pahang, Peninsular Malaysia (2020)
    Naturalis Biodiversity Center
    In:  Blumea: Biodiversity, Evolution and Biogeography of Plants vol. 65 no. 1, pp. 75-82
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: In Peninsular Malaysia, Rafflesia is represented by seven species of which R. kerrii (and R. su-meiae) \nstands out distinctly from the other five. The other five species, R. azlanii, R. cantleyi, R. parvimaculata, R. sharifahhapsahiae and R. tuanku-halimii, are collectively close enough to each other to be referred to as the R. cantleyi \ncomplex after its first-described species, R. cantleyi. Pulau Tioman has a population of R. cantleyi, which, because \nof its island location, is isolated from the mainland complex. This study was conducted to determine morphological \nvariation in a selected location in Pulau Tioman. Twelve flowers were studied with respect to characteristics such \nas wart (blotch) pattern on perianth lobes, warts (dots) on upper surface of the diaphragm, shape of the aperture, \nshape of processes and types of ramenta. These are the characters that have been used to define species in the \nR. cantleyi complex. The variation in the local Tioman population was compared with the variation in the R. cantleyi \ncomplex on the mainland, which is about the same magnitude. This supports the idea that R. cantleyi is a single \nhighly polymorphic species and that the species that have been described in the R. cantleyi complex should be \nreduced to varieties.

    A new species of Dugesia (Platyhelminthes, Tricladida, Dugesiidae) from China, with an account on the histochemical structure of its major nervous system (2020)
    Pensoft Publishers
    In:  Zoosystematics and Evolution vol. 96 no. 2, pp. 431-447
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: By means of an integrated approach, including molecular, morphological, anatomical and histological data, we describe a new species of freshwater flatworm of the genus Dugesia from southwest China, representing the third species recorded for the country. Morphologically, the new species, Dugesia umbonata Song & Wang, sp. nov., is particularly characterised by the presence of a muscularised hump immediately antero-dorsally to a knee-shaped bend in its bursal canal and by an ejaculatory duct that opens subterminally through the dorsal side of the penis papilla. Four molecular datasets (18S rDNA; ITS-1; 28S rDNA; COI) facilitated determination of the phylogenetic position of the new species, which belongs to a clade comprising other species from the Australasian and Oriental regions. We also analysed the structure of its major nervous system by means of the acetylcholinesterase (AChE) histochemical method and compared these results with data available for three other species of Dugesia.

    Integrative taxonomy of araneomorph spiders: Breathing new life into an old science (2021)
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: Taxonomy as a science has accumulated data and knowledge for more than 250 years. The quality and usefulness of the facts recorded in taxonomic literature has greatly improved from the early descriptive texts to the modern data-rich, hypothesis-driven works. Our work illustrates the application of some of the \xe2\x80\x9ce-taxonomic\xe2\x80\x9d tools and the \xe2\x80\x9cNew Taxonomy\xe2\x80\x9d thinking explored in the introduction. Here, we analyzed specimen data contained in legacy taxonomic literature in Chapters 2 and 3\xe2\x80\x94to observe species distribution of one spider group and genital evolution, respectively\xe2\x80\x94and also explored an integrative perspective that involves describing new taxa and testing phylogenetic hypotheses using molecular and morphological data, as done in Chapter 4 and 5.

    Numerous new records of tropical non-indigenous species in the Eastern Mediterranean highlight the challenges of their recognition and identification (2021)
    Pensoft Publishers
    In:  ZooKeys vol. 1010, pp. 1-95
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: New data on 52 non-indigenous mollusks in the Eastern Mediterranean Sea is reported. Fossarus sp. (aff. aptus sensu Blatterer 2019), Coriophora lessepsiana Albano, Bakker & Sabelli, sp. nov., Cerithiopsis sp. aff. pulvis, Joculator problematicus Albano & Steger, sp. nov., Cerithiopsis sp., Elachisina sp., Iravadia aff. elongata, Vitrinella aff. Vitrinella sp. 1 (sensu Blatterer 2019), Melanella orientalis, Parvioris aff. dilecta, Odostomia cf. dalli, Oscilla virginiae, Parthenina cossmanni, Parthenina typica, Pyrgulina craticulata, Turbonilla funiculata, Cylichna collyra, Musculus coenobitus, Musculus aff. viridulus, Chavania erythraea, Scintilla cf. violescens, Iacra seychellarum and Corbula erythraeensis are new records for the Mediterranean. An unidentified gastropod, Skeneidae indet., Triphora sp., Hypermastus sp., Sticteulima sp., Vitreolina cf. philippi, Odostomia (s.l.) sp. 1, Henrya (?) sp., and Semelidae sp. are further potential new non-indigenous species although their status should be confirmed upon final taxonomic assessment. Additionally, the status of Dikoleps micalii, Hemiliostraca clandestina comb. nov. and H. athenamariae comb. nov. is changed to non-indigenous, range extensions for nine species and the occurrence of living individuals for species previously recorded from empty shells only are reported. Opimaphora blattereri Albano, Bakker & Sabelli, sp. nov. is described from the Red Sea for comparison with the morphologically similar C. lessepsiana Albano, Bakker & Sabelli, sp. nov. The taxonomic part is followed by a discussion on how intensive fieldwork and cooperation among institutions and individuals enabled such a massive report, and how the poor taxonomic knowledge of the Indo-Pacific fauna hampers non-indigenous species detection and identification. Finally, the hypothesis that the simultaneous analysis of quantitative benthic death assemblages can support the assignment of non-indigenous status to taxonomically undetermined species is discussed.
