SummaryThree new species: Angraecum archangelicum, A. polyphemus and A. rotundifolium are described for the first time. Pectinariella is evaluated; a case is made to keep it at subgeneric level and the necessary two new combinations are made. Angraecum dasycarpum is neotypified. Finally A. ochraceum and A. setipes are compared with the latter being reduced to a synonym of the former.

AbstractIn continuation of our ongoing revisionary studies on the lichen family Graphidaceae from India, a treatment of 25 species of the lichen genera Fissurina and Hemithecium from India is presented. In our earlier work on the lichen genus Fissurina, 16 species were reported from India. In the present study, 17 additional species of Fissurina from India are recognized. Nine species, viz. Fissurina andamanensis, F. disposita, F. immersa, F. indica, F. microcarpa, F. nicobarensis, F. simplex, F. sporolata, and F. submonospora, are described as new to science. Seven species, viz. Fissurina canlaonensis, F. cingalina, F. comparimuralis, F. monospora, F. nitidescens, F. rubiginosa, and F. subnitidula, are recorded for the first time from India. One species, Fissurina sp. 1, is recorded but not formally described as new due to scanty material. Eight species in the lichen genus Hemithecium, including three new species, viz. H. kodayarense, H. longilirellatum, H. verrucosum, and five new combinations, viz. Hemithecium andamanicum, H. flabillatum, H. flavoalbum, H. flexile, and H. norlabiatum, are also recognized in the present work. A revised key for the identification of all 33 species of Fissurina and 26 species of Hemithecium so far known from India is provided.

AbstractThe ca. 780–740 Ma Chuar Group, Grand Canyon, Arizona, provides an exceptional record of life during the diversification of crown-group eukaryotes, just prior to the first Cryogenian glaciation. We document in detail the assemblage of organic-walled microfossils preserved in fine-grained siliciclastics throughout the unit. In contrast with earlier studies, we primarily used SEM to document fossil morphologies, augmented by transmitted light microscopy, FIB-SEM, and TEM. This resulted in the discovery of new species and the recognition of broad-ranging, intraspecific biological and taphonomic variation in other species. Twenty-two species and five unnamed morphotypes are described, including three new species:Kaibabia gemmulella,Microlepidopalla mira, andVolleyballia dehlerae; two new combinations:Galerosphaera walcottiiandLanulatisphaera laufeldii; and 17 previously described forms. The possible colonial green algaPalaeastrum dyptocranumButterfield in Butterfield, Knoll, and Swett, 1994 and the index fossilCerebrosphaera globosa(Ogurtsova and Sergeev, 1989) Sergeev and Schopf, 2010 (=C. buickiiButterfield, 1994) are described for the first time from Chuar rocks.Lanulatisphaera laufeldii, a locally abundant and globally widespread species characterized by submicrometer filamentous processes that form a reticulate network, may be a useful marker for the time interval just before the appearance of vase-shaped microfossils (VSMs) ca. 740 Ma.Organic-walled microfossil assemblages decline in diversity upsection, coincident with the appearance of VSMs and intermittent euxinia within the basin. Whether this pattern is due to preservational bias related to greater water depth or the higher TOC of upper Chuar rocks or instead reflects biotic turnover related to the spread of euxinic water masses in the basin is unknown.

The genus Pseudophanias Raffray, 1890 is discovered in Japan and Taiwan Island for the first time, with three new species: P. yaimensis Inoue, Nomura & Yin, sp. nov., P. nakanoi Inoue, Nomura & Yin, sp. nov., and P. excavatus Inoue, Nomura & Yin, sp. nov. It is the fifth tmesiphorine genus known from Japan and the first from Taiwan. The genus Chandleriella Hlaváč, 2000 is placed as a junior synonym of Pseudophanias, resulting in the following new combinations: P. termitophilus (Bryant, 1915), comb. nov., and P. yunnanicus (Yin, 2019), comb. nov. A list of world species, and a key to East and South Asian representatives of Pseudophanias is provided.

A review of the aroid tribe Caladieae is presented, and three new species of Caladium Vent. and seven new species of Syngonium Schott are described and illustrated. Two species, C. picturatum K. Koch & C. D. Bouché and C. steudnerifolium Engl., previously considered to be synonymous with C. bicolor (Aiton) Vent., are fully redescribed. New species of Caladium are C. cortesae Croat & E. G. Gonç., C. palaciosii Croat & L. P. Hannon, and C. stevensonii Croat & Delannay. New species of Syngonium are S. adsettiorum Croat, O. Ortiz & J. S. Harrison, S. bastimentoense O. Ortiz & Croat, S. brewsterense Croat & Delannay, S. churchillii Croat & O. Ortiz, S. litense Croat, S. purpureospathum Croat & Raz, and S. tacotalpense Díaz-Jiménez & Croat. Syngonium yurimaguense Engl. is also reported for the first time outside the Amazon Basin.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

AbstractNotes are given on the identity and synonymy of five species of Lepidoptera described by Linnaeus, twenty-eight by Fabricius and two by Ström. Each species dealt with is treated under the apparent valid combination; for each species reference is given to the original description. Twenty-four new species-group name synonyms are introduced and nine new combinations are established: Nemaxera betulinella (Fabr.), Argyresthia arcella (Fabr.), Depressaria depressana (Fabr.), Chrysoesthia drurella (Fabr.), Brachmia blandella (Fabr.), Acleris laterana (Fabr.), Pseudohermenias abietana (Fabr.), Epinotia abbreviana (Fab.) and Acrobasis repandana (Fabr.). During the work two neotypes, twenty-seven lectotypes and two paralectotypes have been designated and are here cited for the first time.

AbstractMorphological, life history, and distributional data are presented for North American species of the subgenus Stygomomonia (sensu stricto) Szalay, 1943. Adults of the seven previously recognized species are redescribed, and deutonymphs of five of these species are described for the first time. Two species, S. (s.s.) neomexicana Cook and S. (s.s.) occidentalis Cook are substantially revised on the basis of an examination of the types and extensive series of newly collected specimens. Three new species are described, S. (s.s.) californiensis on the basis of deutonymphs and adults, and S. (s.s.) imamurai and S. (s.s.) cooki on the basis of adults. A new diagnosis of the subgenus is proposed and discussed, the relationships of the various species are discussed, and a key to deutonymphs and adults of North American species is presented. New distributional data are presented for all species, and dispersal patterns from Pleistocene refugia are discussed.

Studies on the Agalliini leafhoppers collected from the Terrestrial Arthropods of Madagascar inventory project of the Cal-ifornia Academy of Sciences, resulted in the discovery of one new genus Agallidwipa gen. nov. (type-species: A. biramosa sp. nov.) with three new species, A. biramosa sp. nov., A. bispinosa sp. nov. and A. webbi sp. nov. and three new species of the genus Igerna Kirkaldy, I. delta sp. nov., I. flavocosta sp. nov. and I. malagasica sp. nov. Two new combinations proposed are Agallidwipa pauliana (Evans) comb. nov. (from genus Agalliana Oman) and Igerna neosa (Webb) comb. nov. (from genus Stonasla White), a species previously recorded from Aldabra Islands. A previous record of Igerna bi-maculicollis (Stål) from Madagascar is shown most likely to be a case of misidentification. All the taxa are described and illustrated. Keys to species of Agalliini from Madagascar are included along with notes on the distinction between Agal-liana and Agallidwipa.
