A revision of Commersonia including Rulingia (Malvaceae s.l. or Byttneriaceae)

A taxonomic revision and DNA sequence analysis of all species previously attributed to Rulingia R.Br. and Commersonia J.R.Forst. & G.Forst. resulted in two major groupings, referred to a redefined Commersonia and a new genus (Androcalva C.F.Wilkins & Whitlock 2011). In total, 25 species are now recognised within Commersonia, including the type species of Rulingia, and 14 species previously included in Rulingia and 10 in Commersonia. Three of these are described as new (C. apella C.F.Wilkins, C. erythrogyna C.F.Wilkins and C. gilva C.F.Wilkins). A new subspecies, C. magniflora subsp. oblongifolia C.F.Wilkins, is recognised and C. bartramia (L.) Merr. var. tahitensis Dorr is raised to species level as C. tahitensis (Dorr) C.F.Wilkins & Whitlock. Two new combinations are made, Rulingia platycalyx Benth. and R. parviflora Endl. as C. parviflora (Endl.) C.F.Wilkins & Whitlock; and R. cistifolia Steetz and R. rugosa Steetz as C. rugosa (Steetz) F.Muell. The redefined Commersonia is monophyletic and characterised by anthers with sublatrorse dehiscence and mainly hairy staminodes, compared with extrorse dehiscence and glabrous staminodes as seen in Androcalva.

AbstractStudy of new collections of the Wenlock and Pridoli, Silurian, crinoids from Saaremaa, western Estonia, result in taxonomic revision, expanded ranges, and new taxa. Eucalyptocrinites regularis and Periechocrinus laevis are recognized outside of Sweden for the first time. Desmidocrinus laevigatus Ausich et al., 2012 is reassigned to Methabocrinus. Because the type species of Methabocrinus was previously known only from glacial sediments, the age and provenance of this genus are constrained for the first time. A new crotalocrinitid, Velocrinus coniculus new genus and species, is described. Although the Pridoli faunas of western Estonia contain only twelve species-level taxa assigned to nine genera, this fauna is one of the four richest Pridoli faunas known.

Distinctive Group

The genus Anthosphaera Kamptner emend. Kleijne is one of the most taxonomically confusing modern coccolithophores and its species level taxonomy has long been in a state of flux. Based on the review of imaged specimens from our collections, we attempt to rectify the nomenclatural problems and elucidate the obfuscated taxonomy of the genus. Review of included formally and informally described species shows that they are a distinctive group with shared characters, including ten different morphotypes of probable species level. Two of these, including the type species A. fragaria, have been shown to form life-cycle associations with heterococcoliths of the Syracosphaera molischii type. Hence, all species are transferred to Syracosphaera and the new combinations S. periperforata, S. lafourcadii, and S. origami are proposed. In addition, various informally described morphotypes are now formally described as Syracosphaera molischii var. pertusa, S. periperforata var. cylindrata, S. periperforata var. tridentata, S. rotaconica, and S. elevata. urn:lsid:zoobank.org:pub:0E5D4BD7-BC3B-4D30-B319-964AC887DDDE

A checklist comprising information on taxonomy, distribution and host plants is provided for 161 species of jumping plant-lice from the Indian subcontinent (Bangladesh, Bhutan, India, Pakistan, Sri Lanka) based on published records and museum material. In addition there are 15 species recorded in the literature which are identified to genus only. Museum material provides eight new country and two new state (within India) records. The taxonomy is updated and following nomenclatorial acts are proposed: new genus (1), new generic synonymies (2), designation of type species (1), new species synonymies (5), replacement names for primary homonyms at species level (3), new status of subspecies (3), new combinations (23). Toonapsylla Burckhardt, gen. nov. is described for Psylla cedrelae (Kieffer, 1905). The new genus belongs to Mastigimatinae (Calophyidae) and is probably closest related to Bharatiana and Mastigimas, both associated with Cedrela and Toona (Meliaceae). The new genus is diagnosed and a key is provided for the world genera of Mastigimatinae. The Neoptropical genus Allophorina Hodkinson is transferred here from Mastigimatinae (Calophyidae) to Psyllinae (Psyllidae).

Three New Species

The new genus Nefis gen. nov. is described within the tribe Lixini (Coleoptera: Curculionidae) and its systematic position is discussed. The new genus is recognized by short rectangular rostrum, trapezoidal female tergite VIII with truncate apex and long setaceous posterolateral margins, visible 2-segmented labial palpi and protruding sinuate dorsal apex of protibiae. Nefis gen. nov. is close to Larinus Dejean, 1821, Rhinocyllus Germar, 1817, and Bangasternus Gozis, 1882. Three new species are described from Turkey and Afghanistan: Nefis attilai sp. nov., Nefis kabakovi sp. nov. and Nefis korotyaevi sp. nov. Lectotypes are designated for Larinus brevirostris Hochhuth, 1851, Larinus capiomonti Faust, 1885, Larinus reitteri Faust, 1889, Larinus liliputanus Faust, 1890, Larinus exclusus Faust, 1891, Larinus ochroleucus Capiomont v. pachyrrhinus Petri, 1907, and Larinus ochroleucus ssp. carthami Hoffmann, 1957. New synonyms and new combinations are proposed for Nefis brevirostris Hochhuth, 1851 comb. nov. [= Larinus reitteri Faust, 1889 syn. nov.], Nefis liliputanus Faust, 1890 comb. nov. [= Larinus exclusus Faust, 1891 syn. nov.], Nefis pachyrrhinus Petri, 1907 stat. rev. & comb. nov. [= Larinus badghysensis Ter-Minasian, 1982 syn. nov. = Larinus turcmenus Khnzorian, 1990 syn. nov.], Nefis ochroleucus Capiomont, 1874 comb. nov., Nefis capiomonti Faust 1885 comb. nov. Nefis afghanicus Ter-Minasian, 1987 comb. nov., Larinus inflatirostris Petri, 1907 is a nomen nudum. Larinus brevirostris Hochhuth is selected as the type species of the new genus. In total, nine species are included in Nefis. All species are described or redescribed, illustrated, and a key is provided. Host plant data and brief ecological observations are presented.
