Saturnomyces is described as a new genus of the Aspergillaceae in which the ascospores are black but not opaque with three prominent longitudinal ridges. There is an inconspicuous imperfect stage of the Cephalosporium type having long slender phialides each with a small globoid head of viscid phialospores. A single species is described, having been isolated from peat soil collected at Thedford, Ontario.

Branchiura Sowerbyi

The genus Monopylephorus Levinsen, 1884 is revised, and divided into three genera. Monopylephorus includes rubroniveus, limosus, kermadecensis, parvus, irroratus, aucklandicus, and the new species cuticulatus and evertus. Rhizodrilus Smith, 1900 includes lacteus, africanus, pacificus, lowryi, and arthingtonae, the last two being transferred from Torodrilus Cook, 1970 and Rhyacodrilus Bretscher, 1901 respectively. Peristodrilus gen.nov. contains the single species montanus. Two other species (M. longisetosus and M. frigidus) will be referred to a new genus within the Phallodrilinae rather than the Rhyacodrilinae. The single member of the Branchiurinae, Branchiura sowerbyi Beddard, 1892 is related to both Rhizodrilus and Bothrioneurum Stolc, 1888 and is included with the Rhyacodrilinae. Telmatodrilus multiprostatus does not usually have its spermathecae in IX but in X as normal, and is not related to Rhizodrilus.The diffuse prostates in some Rhyacodrilinae may have groups of cells penetrating the muscle layers of the atria, somewhat resembling the clustered cells of the Telmatodrilinae, but with the cell bodies still forming a continuous atrial covering.The forward relocation of the spermathecae in Rhizodrilus and their absence in Bothrioneurum seems to be related to the development of large copulatory bursae in XI and the occupation of much of X by atria and vasa deferentia.

Specific Rank

It is reported that Gaudichaud was correct in describing, under Brachycome Cass., three species, B. triloba, B. dentata and B. spathulata. Reference is made to the nomenclatural status of these species in accordance with the results of a revision of Brachycome by Davis (1948). De Candolle erred in transferring the species to Vittadinia A. Rich, for which the New Zealand V. australis is the type. Reasons are given for regarding V. triloba (Gaudich.) DC. as synonymous with V. australis var. dissecta Benth., and the variety is raised to specific rank. Included with V. australis and V. dissecta in Vittadinia s. str. (i.e. in Vittadinia subgenus Vittadinia) are V. cuneata DC. (a name which can be applied to a complex group of taxa widespread in southern and eastern Australia) and a further 17 species of which the following are new: V. cervicularis (with four varieties), V. constricta, V. condyloides, V. decora, V. eremaea, V. humerata, V. nullarborensis, V. pustulata, V. simulans and V. sulcata, while V. gracilis (J. D. Hook.) N. Burbidge and V. australasica (Turcz.) N. Burbidge are new combinations. V. scabra DC. and a group of taxa which have been referred to it or, incorrectly, to V. macrorhiza (DC.) A. Gray have been placed in a new subgenus of Vittadinia under the name Peripleura. Within this subgenus nine species are recognized: V. scabra DC., V, hispidula F. Muell. ex A. Gray (with two varieties), and the new species V. arida, V. bicolor, V. diffusa, V. obovata, V. sericea, V. spechtii (with two varieties) and V. virgata. With the exception of V. australis which is endemic to New Zealand and V. simulans, a New Caledonian species, all are endemic to Australia; however, V. hispidula has been reported for New Caledonia where it is deemed to be an alien and V. gracilis and possibly V. muelleri appear to have become naturalized in New Zealand. V. brachycomoides (F. Muell.) Benth. becomes the type of a new genus, Camptacra, with two species, both distributed in northern and north-eastern Australia. Eurybiopsis DC. is reinstated, with its single species, E. macrorhiza DC., found only in northern Australia.

The flower beetle genus Aurum new genus (Coleoptera: Scarabaeidae: Cetoniinae: Schizorhinini: Schizorhinina) is described. Aurum is endemic to Australia, and contains a single species, Aurum leonorensis new species, from Western Australia. The genus is compared to the most closely related Australian flower beetle genera, Diaphonia Newman, 1840, Aphanesthes Kraatz, 1880, and Chondropyga Kraatz, 1880. Ecological observations and the collecting localities are detailed for Aurum leonorensis.

Based on traditional morphological and phylogenetic analyses (ITS, LSU, tef-1α and β-tub) of psathyrelloid specimens collected from China, four new species are here described: Heteropsathyrella macrocystidia, Psathyrella amygdalinospora, P. piluliformoides, and P. truncatisporoides. H. macrocystidia forms a distinct lineage and groups together with Cystoagaricus, Kauffmania, and Typhrasa in the /Psathyrella s.l. clade, based on the Maximum Likelihood and Bayesian analyses. Thus, the monospecific genus Heteropsathyrella gen. nov. is introduced for the single species. Detailed descriptions, colour photos, and illustrations are presented in this paper.

AbstractThe extinct “New World stilt-legged”, or NWSL, equids constitute a perplexing group of Pleistocene horses endemic to North America. Their slender distal limb bones resemble those of Asiatic asses, such as the Persian onager. Previous palaeogenetic studies, however, have suggested a closer relationship to caballine horses than to Asiatic asses. Here, we report complete mitochondrial and partial nuclear genomes from NWSL equids from across their geographic range. Although multiple NWSL equid species have been named, our palaeogenomic and morphometric analyses support the idea that there was only a single species of middle to late Pleistocene NWSL equid, and demonstrate that it falls outside of crown group Equus. We therefore propose a new genus, Haringtonhippus, for the sole species H. francisci. Our combined genomic and phenomic approach to resolving the systematics of extinct megafauna will allow for an improved understanding of the full extent of the terminal Pleistocene extinction event.

The genus Otraleus Günther, 1935 is recorded from the Philippines for the first time. Four new species, Otraleus bellemansae sp. nov., O. applai sp. nov., O. christianae sp. nov. and O. elizabethae sp. nov., are described from the highlands of Northwestern Luzon. The characters allowing separation from O. hypsimelathrus Günther, 1935 and O. labanrataensis Soew-Choen, 2016, are given. A new genus closely related to Otraleus, Capuyanus gen. nov., is described with a single species, C. magwilangi sp. nov., as type-species. An identification key and distribution maps are provided for all species.

A new monotypic genus of aorid amphipod Propejanice gen. nov. is described and figured from material collected in Brazil. The single species, P. lagamarensis sp. nov. was collected from artificial plates suspended in the sea in Paraná and Sao Paulo States, Brazil. The new genus appears to be morphologically closest to the genus Janice Griffiths, 1973 from Moçambique, from which it differs in the carpochelate male gnathopod 1. Both genera are phylogenetically close to the genus Grandidierella Coutière, 1904.

To date, the feather mite family Ptyssalgidae (Acariformes: Analgoidea) has been known from a single species associated with hummingbirds (Apodiformes: Trochilidae). Here, based on our collecting in Mexico, we describe (i) a new genus and species, Tyrannoptyssalges striatus gen. n., sp. n., from a passerine host Tolmomyias sulphurescens (Passeriformes: Tyrannidae) and (ii) four new species of the genus Ptyssalges Atyeo and Gaud, 1979 from hummingbirds (Apodiformes: Trochilidae): Ptyssalges amaziliae sp. n. from Amazilia rutila (Delattre) (type host), A. candida (Bourcier & Mulsant) and A. yucatanensis (Cabot), P. anthracothoracis sp. n. from Anthracothorax prevostii (Lesson, R.), P. atyeoi sp. n. from Phaethornis longirostris (Delattre), and P. campylopteri sp. n. from Campylopterus curvipennis excellens (Wetmore). In addition, we redescribe Ptyssalges major (Trouessart, 1887), the type species of the genus, based on newly collected material from the type host, Eutoxeres aquila, from Panama. Standard morphological descriptions of all mite species are supplemented by CO1 barcoding sequence data. In the genus Ptyssalges, CO1 K2P interspecific genetic distances were 11.39–11.89%, while distances between the single species of Tyrannoptyssalges and species of the genus Ptyssalges were 16.34–17.87%. New, amended diagnoses for the family Ptyssalgidae and the genus Ptyssalges and a key to all known ptyssalgid species are provided. Preliminary hypotheses on the origin and ancestral host associations of ptyssalgids are briefly discussed.
