Concepts of the family Hyolithidae Nicholson fide Fisher and the genera Hyolithes Eichwald and Orthotheca Novak have been expanded through time to encompass a variety of morphologically dissimilar shells. The Hyolithidae is here considered to include only those hyolithid species which have a rounded (convex) dorsum; slopes on the dorsum are inflated, and the venter may be flat or slightly inflated. Hyolithes encompasses species which possess a low dorsum and a prominent longitudinal sulcus along each edge of the dorsum; the ligula is short and the apertural rim is flared. The emended concept of Orthotheca includes only those species of orthothecid hyoliths which have a subtriangular transverse outline and longitudinal lirae covering the shell on both dorsum and venter.Eighteen species of Hyolithes and one species of Orthotheca from the Appalachian region and Western Interior were reexamined in light of more modern taxonomic concepts and standards of quality for type material. Reexamination of type specimens of H. similis Walcott from the Lower Cambrian of Newfoundland, H. whitei Resser from the Lower Cambrian of Nevada, H. billingsi Walcott from the Lower Cambrian of Nevada, H. gallatinensis Resser from the Upper Cambrian of Wyoming, and H. partitus Resser from the Middle Cambrian of Alabama indicates that none of these species represents Hyolithes. Hyolithes similis is here included under the new genus Similotheca, in the new family Similothecidae. Hyolithes whitei is designated as the type species of the new genus Nevadotheca, to which H. billingsi may also belong. Hyolithes gallatinensis is referred to Burithes Missarzhevsky with question, and H. partitus may represent Joachimilites Marek. The type or types of H. attenuatus Walcott, H. cecrops Walcott, H. comptus Howell, H. cowanensis Resser, H. curticei Resser, H. idahoensis Resser, H. prolixus Resser, H. resseri Howell, H. shaleri Walcott, H. terranovicus Walcott, and H. wanneri Resser and Howell lack shells and/or other taxonomically important features such as a complete aperture, rendering the diagnoses of these species incomplete. Their names should only be used for the type specimens until better preserved topotypes become available for study. Morphology of the types of H.? corrugatus Walcott and “Orthotheca” sola Resser does not support placement in the Hyolitha; the affinities of these species are uncertain.

While preparing a revised treatment of the family Combretaceae for “Flora of India Project,” our attention was drawn on Terminalia paniculata Roth (1821: 383) which was described on the basis of a specimen collected by Benjamin Heyne from peninsular India. The species is well documented in Indian Floras (e.g. Wight & Arnott 1834, Beddome 1869, Brandis 1874, Clarke 1878, Cooke 1903, Talbot 1911, Gamble 1919 and Chandrabose 1983). Gangopadhyay & Chakrabarty (1997) in their revision of the family Combretaceae of Indian subcontinent mentioned that the type of this species is not extant. The type material of T. paniculata housed in the Berlin herbarium (B; herbaria acronyms follow Thiers 2017) was presumably destroyed during the World War II. In the Kew herbarium (K), there is a collection by Benjamin Heyne (K000786096: image!) identified and listed in Wallich’s Numerical List as T. triopteris B.Heyne ex Wallich (1831: no. 3980B). This material contains two twigs, one flowering and the other fruiting and this appears to be a specimen not seen by Roth (1821) since he clearly mentioned in the protologue: “Fructum non vidi.” Thus, as per the provisions of the Code (Mc Neill et al., 2012), as there is no other extant original material (Article 9.7) traceable, a neotype (Articles 9.11 and 9.13) is designated here for T. paniculata from Peninsular India, where Benjamin Heyne made botanical explorations (Burkill, 1965). The neotype specimen is housed in the Central National Herbarium, Botanical Survey of India, Howrah, India (CAL) and its duplicate in the Madras Herbarium, Botanical Survey of India, Southern Regional Centre, Coimbatore, India (MH).

The family Moitessieriidae includes minute dioecious gastropods exclusively inhabiting subterranean waters, including thermal ones. Only empty shells were collected in most species, the vast majority of them are described from their gross shell morphology alone. Several visits to a site are usually required to obtain at least some living individuals. High variability in shell morphology and the lack of diagnostic features, coupled with anticipated high levels of endemism, has resulted in a long list of nominal moitessierid species. Type specimens stored as empty shells omit unambiguous identification and delimitation of species boundaries. Due to inaccessibility of cave animals and consequent lack of material suitable for molecular analysis, the phylogenetic relationships, as well as the taxonomy of the family at genus/species level, are far from being understood. The anatomy of the family is also poorly known and provided only for a few taxa. The distinctness of the Moitessieriidae has sometimes been questioned, and their monophyly not proved. Twelve species of the Balkan Moitessieriidae are considered: two species of Paladilhiopsis, two species of Bythiospeum, six species of Iglica, Costellina turrita and Lanzaia bosnica. The shell morphology of each species, as well as the reproductive system of Paladilhiopsis and Iglica, were analysed. DNA sequences of nuclear histone H3, ribosomal 18S, ribosomal 28S and mitochondrial cytochrome oxidase subunit I (COI) were applied to infer phylogenetic relationships among the taxa. The sequences of Bythiospeum from GenBank have been used to infer relationships between Bythiospeum and Paladilhiopsis that were recently synonymized. Paladilhiopsis and Iglica are distinct, but closely related genera, as is the genus Bythiospeum, which does not occur in the Balkans. Its relationships with both former taxa remain unresolved. The Moitessieriidae are clearly distinct from all other families of the Truncatelloidea, however, their monophyly remains doubtful.

Gastridium ventricosum (Poaceae) is the currently accepted name of Gouan’s Agrostis ventricosa, whose previous unclear type designation is briefly discussed and superseded. All relevant sources, specimens, illustrations, and the author’s relevant correspondence are carefully evaluated, the original material and possible type specimens are thoroughly discussed for the purpose to fix the precise taxonomic application of the name. We have chosen as the best admissible lectotype a newly discovered, well-preserved specimen enclosed in a letter sent by Antoine Gouan to Carl Linnaeus in 1761. This letter, Ref. L2998, is preserved in the Linnean Society of London’s collections (LINN) and was drawn up a year before the publication of the species name.

Sematophyllum latifolium Brotherus (1911: 362), known only from the type collection, was originally described by Brotherus (1911) based on a collection made by C.C. Hosseus from Mt. Doi Suthep (Doi Sutäp), in northern Thailand. Pollawatn (2008) revised the family Sematophyllaceae s.l. in Thailand but did not see the type specimen of S. latifolium. During the study of Hosseus’s collections, however, we found two duplicates of type specimens of S. latifolium one located in H-BR and one in M. We found that several critical features of S. latifolium, such as the 1) irregular-pinnately branching habit with the erect flagelliform branches (Fig. 1A), 2) stem and branch leaves strongly differentiated (Fig. 1B−F), and 3) brotherelloid type alar cells often divided into larger hyaline cells towards leaf margins (Fig. 1G), were indistinguishable from those in the type material of Wijkia surcularis (Mitten 1859: 112) Crum (1971: 173), a common species found growing from India to Indochina (Gangulee 1980; Tan & Iwatsuki 1993; Tan & Jia 1999; Jia et al. 2005). Thus, we here propose S. latifolium as a new synonym of W. sucularis. In the protologue, Brotherus (1911) did not designate the holotype, therefore, it is necessary to select a lectotype for S. latifolium ((see Art. 9.11 of the Shenzhen Code (Turland et al. 2017)). We designate Hosseus’s collection (Hosseus s.n.) in H-BR (H) as the lectotype of the name S. latifolium.

Mesodiphthera Tillyard, 1919, from the Late Triassic of Queensland, the oldest cicada (Hemiptera: Cicadomorpha: Cicadoidea: Tettigarctidae)

New specimens of its type species from the Queensland Late Triassic (Norian) (~227–~208.5 Ma) fossil insect locality at Dinmore have revealed that the old and obscure Late Triassic genus Mesodiphthera Tillyard, 1919, from nearby Denmark Hill, is a tettigarctid cicada, the earliest record of the family and the oldest cicada. The genus is distinguished by the combined presence of three characters: the primary forks of R and M at about the same level, midway between the basal cell and the nodal line; RA2 with four or five terminal branches; and the inter-medial cross-vein backwardly inclined, running between M2 and M3. Of the three species originally ascribed to Mesodiphthera by Tillyard, only its type, M. grandis Tillyard, 1919, is retained in the genus. The other two species differ significantly from the type and are transferred to Tardilly gen. nov., which is similar to Mesodiphthera in the more or less aligned primary forks of R and M placed at about midway between the basal cell and the nodal line, and the backwardly inclined inter-medial cross-vein which runs between M2 and M3. It differs, however, in its smaller size, broader costal space, three-branched M3+4, and differently shaped CuA and CuA2. The new material, all of which is of M. grandis, provides a complete picture of the shape, colour and venation of its tegmen, whereas Tardilly prosboloides (Tillyard) comb. nov., 1922 and Tardilly dunstani (Tillyard) comb. nov., 1922 are still known only from their poorly preserved type specimens. Mesodiphthera and Tardilly exhibit a number of presumed plesiomorphies, viz the costal space much wider than the CuA cell, the basal cell strongly narrowed apically, and the post-nodal cross-vein series closer to the nodal line than the apex, which place it in the probable paraphyletic subfamily Cicadoprosbolinae. A more informed assessment of their relationships, however, must await a comprehensive analysis of the now 29 fossil genera of the family. The Tettigarctidae were the only cicadas of the Mesozoic and the discovery in the Triassic of Australia of Mesodiphthera and Tardilly clearly distinct from the 24 previously known Mesozoic genera, further demonstrates the family’s high degree of structural diversity, and emphasises its almost world-wide distribution in that Era.

Both the genus Shastasaurus and the family Shastasauridae have long been hard to define due to the fragmentary nature of the type specimens. Consequently, recent interpretations of the genus have been based almost entirely on Shastasaurus neoscapularis from the Late Triassic Pardonet Formation of British Columbia. Two new specimens of this taxon, from Pink Mountain, British Columbia, demonstrate that it does not belong in the genus Shastasaurus. This paper describes the new specimens, and refers the species to Metashastasaurus gen nov. Post-cranially, the skeleton of Metashastasaurus resembles that of shastasaurids, differing primarily only in the shape of the scapula and fibula. However, the skull has a unique combination of characters, including large diamond-shaped frontals that enter the supratemporal fenestrae, and very narrow posterior extensions of the nasals, which contact the postfrontals. It also differs from the skull of Shastasaurus in the presence of both a parietal ridge and postparietal shelf. This is a combination of derived characters previously known only in Jurassic forms. The front limb has four proximal carpals and four digits, indicating that previous reconstructions were based on incomplete material. Shastasaurus pacificus Merriam 1895, the type species of the genus Shastasaurus, must be considered a nomen dubium, making the genus Shastasaurus invalid. Until this problem is clarified, the use of the generic name Shastasaurus should be restricted to Merriam's type specimens, of which only Shastasaurus alexandrae and Shastasaurus osmonti are based on adequate material.

Three Japanese species of the genus Pulvinaria Targioni Tozzetti (P. araliae Shinji, 1935, P. enkianthi Takahashi, 1955 and P. flava Takahashi, 1955) are redescribed and illustrated based on type specimens and some newly collected adult female specimens. Lectotypes are designated for P. enkianthi and P. flava from syntypes of these species and, in the absence of any original material, a neotype is designated for P. araliae using a specimen collected from the type locality. To facilitate comparisons, a table of diagnostic morphological character states of the redescribed species and the type species of the genus, P. vitis (Linnaeus, 1758), is also provided.

In the course of revising the family Commelinaceae in India, it has been found that no type was indicated in the protologue of Streptolirion volubile Edgew. Thus, it warrants typification under execute Art. 9.2 of the International Code of Nomenclature (McNeill & al. 2012). Though not cited explicitly in the protologue, we consider Edgeworth’s own material collected in 1844 from the Indian Himalaya and annotated by him to constitute original material and therefore appropriate for typification. We herein designate a specimen at Kew that unequivocally agrees with the protologue as lectotype.
