AbstractThe biofacies of the Lower Palmatolepis rhenana Biozone to Palmatolepis triangularis Biozone in the Mae Sariang section, northwestern Thailand, are marked by alternations of Palmatolepis-dominated biofacies and Polygnathus-dominated biofacies related to fluctuations in seawater depth. Fine-grained limestone accumulated through the Lower Palmatolepis rhenana Biozone, Upper Palmatolepis rhenana Biozone, Palmatolepis linguiformis Biozone, Palmatolepis subperlobata Biozone, and Palmatolepis triangularis Biozone. A regression in the Upper rhenana Zone was followed by a recovery transgression that extended up through the linguiformis Zone. Conodont faunas increased until near the end of the linguiformis Zone, but in the overlying subperlobata Zone and triangularis Zone, conodont numbers dropped and most conodont species disappeared. It is possible the event coincides with a glacially forced regression, but there is no evidence of this in the section apart from a positive spike in δ13C. Another possible cause of the global marine extinction event is toxic levels of metals resulting from widespread volcanism. New taxa in this paper are Palmatolepis chaemensis new species, Palmatolepis thamensis new species, and Polygnathus tenellus surinensis new subspecies.UUID: http://zoobank.org/f2b55ba8-fe49-46f6-a2d5-bfd0208f1460

Review of specimens and names of Faramea Aubl. (Rubiaceae, Coussareeae) has required new nomenclatural combinations, clarified the identities of some previously described species, and discovered some new taxa. Here we transfer two Faramea names, F. suaveolens Duchass. and F. panurensis Müll. Arg., to Coussarea Aubl.; review the identities of F. cuencana Standl., F. multiflora A. Rich., F. oblongifolia Standl., F. parvibractea Steyerm., F. spathacea Müll. Arg. ex Standl., and F. suerrensis (Donn. Sm.) Donn. Sm.; lectotypify F. multiflora and F. panurensis; transfer to Faramea and lectotypify Rudgea scandens K. Krause; and describe 13 new species and two new subspecies: F. camposiana C. M. Taylor of Ecuador and Peru, F. foreroana C. M. Taylor of Colombia, F. fosteri C. M. Taylor of western South America, F. galerasana C. M. Taylor of Ecuador, F. grayumiana C. M. Taylor of Central America, F. kampauicola C. M. Taylor of Ecuador and Peru, F. neilliana C. M. Taylor of western South America, F. premontana C. M. Taylor of Ecuador, F. quijosana C. M. Taylor of Ecuador, F. ramosiana C. M. Taylor of Colombia, F. reyneliana C. M. Taylor of Peru, F. stoneana C. M. Taylor with two subspecies from Central and western South America, F. suerrensis subsp. miryamiae C. M. Taylor from Colombia, and F. vernicosa C. M. Taylor of Ecuador and Peru.

A new species and eight new subspecies of Papilionoidea discovered in Vietnam between 2002 and 2020 are described and illustrated. The status of two taxa are revised. New taxa include Pieridae: Delias sanaca bidoupa Monastyrskii & Vu subspec. nov. and Talbotia naganum aurelia Monastyrskii & Vu subspec. nov.; Nymphalidae: Abrota ganga pulcheria Monastyrskii & Vu, subspec. nov.; Bassarona recta consonensis Monastyrskii & Vu, subspec. nov.; Pantoporia bieti aurantina Monastyrskii & To subspec. nov.; Ragadia latifasciata cristata Monastyrskii & Vu, subspec. nov.; Ragadia latifasciata crystallina Monastyrskii & Vu, subspec. nov.; Faunis indistincta luctus Monastyrskii & Vu subspec. nov. & Aemona gialaica Monastyrskii, K. Saito & Vu, spec. nov. The taxon infuscata Devyatkin & Monastyrskii, previously described as the subspecies Aemona tonkinensis infuscata, was elevated to the species level, while the taxon critias (Ragadia critias Riley & Godfrey) was reduced to a subspecies. Three Satyrinae species were recorded from Vietnam for the first time: Palaeonympha opalina Butler, 1871; Ypthima motschulskyi Bremer & Grey, 1853; and Ragadia latifasciata Leech, 1891.

New taxa and synonymies in the group of Liptena opaca (Kirby, 1890) (Lepidoptera, Lycaenidae, Poritiinae). A lectotype of Liptena opaca (Kirby, 1890) is designated, and the status of three of its subspecies are revised: ugandana Stempffer, Bennett & May, 1974, is raised to specific rank, centralis Stempffer, Bennett & May, 1974, is synonymized with L. opaca gabunica, and sankuru Stempffer, Bennett & May, 1974, becomes a subspecies of L. albomacula Hawker-Smith, 1933. Liptena ouesso Stempffer, Bennett & May, 1974, is synonymized with L. immaculata Grünberg, 1910. Six new species are described, four from Cameroon (L. arnouxi n. sp., L. laguerrei n. sp., L. mariae n. sp. and L. perconfusa n. sp.), one from eastern Nigeria (L. brophyi n. sp.), and one species (L. restricta n. sp.) as well as a new subspecies (L. immaculata orientis n. ssp.) from north-eastern Democratic Republic of the Congo.

Lower bathyal sediments representing portions of the Luisian and Mohnian stages of Kleinpell (1938) occur on a submarine ridge near Tanner Bank, offshore southern California. The presence of abundant and well-preserved calcareous nannofossils, diatoms, silicoflagellates, radiolarians and foraminifera allows accurate correlations with the onshore type sections of these stages. In terms of the calcareous nannofossil zones, the age range is from the Sphenolithus heteromorphus Zone to the Discoaster kugleri Zone. Although abundant benthic foraminifera indicative of the Luisian and Mohnian are present, they are accompanied by species more characteristic of the Pliocene Repettian Stage of Natland (1952) and the Pliocene-Miocene “Delmontian” Stage of Kleinpell (1938). Many of these latter species live today at lower bathyal depths (below 2,000 m), others occur in lower bathyal sediments as old as Oligocene, but are absent in the onshore type sections of the Luisian and Mohnian stages in coastal California. We ascribe their absence in onshore sequences to deposition at middle bathyal depths. The known chronostratigraphic ranges of several species are extended and five new species and two new subspecies of benthic foraminifera are described.The following new taxa are described: Bolivina pelita n. sp., Cassidulinella inflata n. sp., Globocassidulina undulata n. sp., Cibicidoides mckannai miocenicus n. subsp., C. mckannai sigmosuturalis n. subsp., Pullenia fragilis n. sp., Parafissurina inornata n. sp.

Two new species of Convolvulus (Convolvulaceae), C. excelsus R.R.Mill and C. infantispinosus R.R.Mill, are described from Saudi Arabia. Convolvulus excelsus, an exceptionally tall species, has affinities with C. erinaceus Ledeb. but is phytogeographically disjunct from that and other allied species. Two new subspecies are also described: Convolvulus hystrix Vahl subsp. dhofarica R.R.Mill, from Oman, and C. oxyphyllus Boiss. subsp. sheilae R.R.Mill, from Saudi Arabia. Each novelty is given a provisional IUCN conservation assessment.

А new species and a new subspecies of Satyrium Scudder, 1876 (subfamily Theclinae, tribe Eumaeini) from the subgenera Superflua Strand, 1910 and Armenia Dubatolov & Korshunov, 1984 respectively are described from Bamyan Province, Central Afghanistan—S. (S.) skrylniki sp. n. and S. (A.) hyrcanica bamiana ssp. n. The new species of Superflua belongs to the Iranian complex of species. It inhabits the territory of Afghanistan, being isolated from two other species of the subgenus known from the territory in question. The new subspecies of Armenia is also found in isolation both from the nominate subspecies and two Middle and Central Asian subspecies. Both findings clarify some aspects of zoogeography of the Central Afghanistan mountains.

Seven new troglobitic leiodid beetle taxa (six new species and one new subspecies) from several caves and pits in the Balkan Peninsula (Bosnia and Herzegovina and Serbia) are described and diagnosed. Three new species belong to the genus Adelopidius Apfelbeck, 1907, two—to the genus Pholeuonopsis Apfelbeck, 1901, one—to the genus Leonhardia Reitter, 1901, while a new subspecies belongs to the genus Apholeuonus Reitter, 1889. All important morphological characteristics of the new taxa have been mentioned and imaged, including the aspects of the male and female genitalia. The new leiodid taxa are properly distinguished from their relatives and are endemics of the Dinaric mountain chain. A key to Adelopidius taxa is added.
