Abstract. The dinoflagellate cyst genus Epiplosphaera Klement 1960 and its species have been studied in material from the Oxfordian and Kimmeridgian of Poland. The taxonomic history of the genus is summarized and the morphology is discussed. The type species Epiplosphaera bireticulata differs from other representatives of the genus in having high septa which are dissected distally. Additional septa in E. bireticulata form a second reticulum inside the parasutural septa. Epiplosphaera reticulata differs from the other species by having low spines and low, smooth septa. The septa form a second reticulum within the parasutures, as in the case with E. bireticulata. Epiplosphaera areolata has high spines, but almost no reticulum or parasutures. Epiplosphaera reticulospinosa is intermediate between E. bireticulata and E. areolata. It has a mixture of both high and low septa between the spines. Epiplosphaera gochtii has low spines and few, low septa between some of the spines. Epiplosphaera ornata is regarded as a junior synonym of E. gochtii.

The nomenclatural and taxonomic history of Cassinia R.Br. is reviewed, particularly in relation to its close relative Ozothamnus R.Br. Current concepts of Ozothamnus are shown to be unsatisfactory, with that genus consisting of a 'core' of approximately 25 species (including the type species O.�rosmarinifolius R.Br.) which are defined by their possession of inner phyllaries with radiating tips and no paleae (or only very few) between the florets, and other characters. The other 25 species (approximate) of 'Ozothamnus' need re-examination and probable placement elsewhere (but not in Cassinia). Cassinia can be satisfactorily defined as a genus distinct from 'core' Ozothamnus. As a precursor to a series of papers describing the species of Cassinia (including a large number of new taxa), Cassinia is divided into two subgenera, seven sections and two series. New taxa described are Cassinia copensis Orchard, Cassinia subg. Achromolaena (Cass.) Orchard, Cassinia sect. Complanatae Orchard, Cassinia sect. Venustae Orchard, Cassinia sect. Leptocephalae Orchard, Cassinia sect. Costatae Orchard, Cassinia sect. Arcuatae Orchard, Cassinia (sect. Cassinia) ser. Cassinia and Cassinia (sect. Cassinia) ser. Longifoliae Orchard.

Abstract. A review of the taxonomic history of the agglutinated (benthonic) foraminiferal genus Cribrostomoides Cushman, 1910 reveals much confusion concerning its type species, coiling mode and apertural characteristics. We believe the originally designated type species of Cribrostomoides Cushman, 1910, C. bradyi Cushman, 1910, to be no more than varietally (i.e. infra-subspecifically) distinct from, and therefore a junior synonym of, Haplophragmoides subglobosus Cushman, 1910. The coiling of Cribrostomoides, as typified by C. subglobosus (Cushman, 1910), is in the form of an involute streptospire characterised by a repeated alternation in axis. The aperture of the genus is equatorially or asymmetrically placed and interio-areal and single (in megalospheric and juvenile microspheric specimens) to areal and multiple (in microspheric adults). In order to stabilise the concept of Cribrostomoides, we have designated lectotypes for both C. bradyi and H. subglobosus, and have also emended the generic diagnosis of Loeblich and Tappan (1987). Criteria for the discrimination of Cribrostomoides emend, herein and allied genera are tabulated.

Abstract. The taxonomic identity of the dinoflagellate cyst genus Polygonifera Habib, 1972 is confirmed, through the recognition of additional morphological characters during the study of specimens from Early-Middle Cretaceous sediments of India. A revised definition of this genus is presented. Leberidocysta Stover &amp; Evitt, 1978 is considered a subjective junior synonym of Polygonifera and its type species Leberidocysta (ex: Hexagonifera) chlamydata (Cookson &amp; Eisenack) is transferred to Polygonifera. The other species placed in Leberidocysta are provisionally reattributed to other genera, becoming Craspedodinium (ex: Hexagonifera) defloccata (Davey), Craspedodinium (ex: Palaeostomocystis) pergamentacea (Burger), Hexagonifera laticaudata Vozzhennikova and Hexagonifera scabrata Jain &amp; Taugourdeau-Lantz. A new species, Polygonifera eisenackii, is described. Morphological differences between the camocavate genera Polygonifera and Dingodinium are clarified.

In this work, it is explained why previous authors who considered that Canthidium lentum Erichson, 1947 (Coleoptera: Scarabaeidae: Scarabaeinae) was fixed as the type species of Canthidium Erichson, 1847 in Robert Lucas’ 1920 catalogue of Coleoptera genera were mistaken. Instead, the first authors to designate a type species for Canthidium were Martínez et al. in 1964, who designated C. thalassinum Erichson, 1847. Since both species are currently placed in different subgenera, the subgeneric classication must change: Eucanthidium Halffter & Martínez, 1986 is a new junior synonym of Canthidium, while the subgenus previously considered to be Canthidium (Canthidium) is changed to Canthidium (Neocanthidium) Martínez et al., 1964 based on the revalidation of the latter name. A checklist containing information on the type locality, type material, synonymy, and distribution of all the 172 valid species included in the genus (72 in the nominotypical subgenus, 69 in Neocanthidium, and 31 as incertae sedis) is presented, as well as a review of the taxonomic history of Canthidium and the new synonymy between C. (C.) ardens Bates, 1887 and Canthidium ardens mutatum Bates, 1887.

Proteocephalid tapeworms (Cestoda) are one of the dominant groups of intestinal parasites of Neotropical catfishes (Siluriformes), especially pimelodids (de Chambrier et al. 2015). The long and convoluted taxonomic history of species of Chambriella Rego, Chubb & Pavanelli, 1999 has been disentangled only recently by Alves et al. (2017). These authors erected a new genus, Riggenbachiella Alves, de Chambrier, Luque & Scholz, 2017, to accommodate R. amazonense Alves, de Chambrier, Luque & Scholz, 2017 (type-species) and R. paranaense (Pavanelli & Rego, 1989) (previously Chambriella paranaensis), parasites of pimelodid catfishes.

Recently, in an examination of the phylogenetic relationships among the mole-rats of the family Bathyergidae (Mammalia: Rodentia), Ingram et al. (2004) documented molecular evidence for the recognition of the Cryptomys mechowii species group at the generic level and resurrected the name Coetomys Gray, 1864 for this group. Subsequent literature review revealed that Coetomys is not available to this species group, being a junior synonym of Cryptomys Gray, 1864. Here, we describe and diagnose Fukomys genus novum. In addition, we discuss the taxonomic history of this group in an attempt to reduce the nomenclatural confusion that has plagued studies of the Bathyergidae for over a century.

Pedicularis L. series Curvipes (Prain) Hurus. (=Pedicularis [unranked] Curvipes Prain) in the Orobanchaceae (often included in the Scrophulariaceae s.l.) is revised. It is demonstrated that the correct name for the series is Pedicularis ser. Curvipes, not Pedicularis ser. Curvipedes as used by at least two previous authors. Arguments are presented for the retention of the three existing species, Pedicularis curvipes Prain, Pedicularis nagaensis H.L.Li and Pedicularis amplicollis T.Yamaz., and the taxonomic history of each is summarized. Pedicularis curvipes from Sikkim and Pedicularis nagaensis from NE India are very similar but can be distinguished on corolla and seed characters. Flowering material of Pedicularis curvipes collected from cultivated material of uncertain origin in 1900 is positively identified as that species for the first time. The known geographical range of Pedicularis nagaensis, which was previously believed to be endemic to a restricted area of Nagaland in NE India, is extended to include Manipur. Pedicularis amplicollis from Bhutan is distinct from both the other two and easily separable by its woolly, 4-lobed calyx. A key to the series and formal taxonomic accounts of each species are provided. The relationships of the series with related series, particularly Pedicularis ser. Furfuraceae, are discussed.

Taxonomic and nomenclatorial revision of the genus Cheilonycha Lacordaire, 1842 with type species Cheilonycha chalybea (by original monotypy), based on Cicindela chalybea Dejean, 1825, is presented. It is concluded here that a subsequent type designation by Horn (1910), who without any explanation mentioned Ch. auripennis (Lucas, 1857) as the type species of the genus, was unjustified and must be considered invalid according to ICZN (1999). Examinations of type specimens have revealed that Cheilonycha auripennis sensu auctorum (sensu Horn 1922 and subsequent authors) is a complex of taxa. As a result, one new subspecies of Ch. auripennis (Lucas, 1857) and one new species of the genus are described and the following taxa of Cheilonycha are recognized and presented here: Ch. chalybea (Dejean, 1825), Ch. a. auripennis (Lucas, 1857), Ch. a. chiquitosiana ssp. nov. and Ch. bucephalauripennis sp. nov. Type specimens of Ch. a. angustedilatata (W. Horn, 1922) based on Odontochila (Chilonycha) auripennis angustedilatata W. Horn, 1922, proved to be fully conspecific with the type specimens of Ch. auripennis based on Cicindela auripennis Lucas, 1857. Consequently, Ch. a. angustedilatata syn. nov. is treated here as a junior synonym of Ch. a. auripennis. The history of the taxonomy of these taxa, their distribution and biology, including photographs of the termitophilous habitat, relevant lectotype designations, descriptions (redescriptions respectively) and illustrations in colour photographs of the habitus, diagnostic characters and variability are provided.

The genus Adelocoenia ORBIGNY, 1849, is revised and a neotype is designated for its type species Astrea castellum MICHELIN, 1844. For various reasons that lie in the taxonomic history of scleractinian corals, it has become a difficult task to reliably assign Mesozoic corals having the combined features of plocoid corallite integration and the absence of a columella. Therefore, many such genera are in need of revision, one of which is Adelocoenia. In addition to the revision of the type species, Jurassic species grouped within Adelocoenia are revised using type material when it was possible. Many new synonymies are proposed based mainly on characters such as symmetry and dimensions of skeletal features. Another consequence is that most species previously grouped with Pseudocoenia ORBIGNY are transferred to Adelocoenia. Furthermore, we present a clarified view of the paleogeographical and stratigraphical distributional patterns of the genus Adelocoenia, according to which Adelocoenia had its first appearance during the Early Jurassic, represented by a single specimen known from the Sinemurian of France. Subsequently, this genus had a significant increase in both distribution and diversity during the Middle Jurassic. The pinnacle of its success followed in the Late Jurassic during which Adelocoenia had its greatest morphological disparity and taxonomical diversity, and its largest geographical distribution. The genus survived in the Cretaceous record. Throughout its history, Adelocoenia predominantly occurred in inner platform environments that were located in low latitudes.
