A New Species

A new species, Macrobiotus derkai sp. nov., is described from a moss sample collected in the alpine zone of Sierra Nevada del Cocuy Mts (NE Colombia). It differs from the most similar species, Macrobiotus huziori Michalczyk & Kaczmarek, 2006 mainly in the location of the second macroplacoid and in the dimensions of accessory points on the claws. Eggs of the new species have the same type of areolation as eggs of M. huziori but they differ from the latter in the size and number of processes. The differences between the new species and others having similar number and shape of placoids are discussed. An identification key for these species is also provided. A round depression on the dorsal head cuticle is reported in Tardigrada for the first time. The results of a morphometric analysis of the new species are also given.

A New Species

As a part of an assessment of loricariid catfishes inhabiting the Andes of Colombia, specimens belonging to an interesting new species were identified. The new species is described herein, and it is tentatively included in the genus Cordylancistrus. The new species can be easily distinguished among its congeners by the presence of a unique diagnostic character: a fleshy keel or excrescence, black or dark brown, over the posterior tip of supraoccipital. Specimens of the new species were captured in rivers of the Sierra Nevada de Santa Marta and the Sierra de Perijá that drain to the Magdalena River Basin and Caribbean Sea. The occurrence of one species of Cordylancistrus in the Sierra Nevada de Santa Marta could have interesting biogeographic implications for hypotheses related to the geological history of northwestern corner of South America or to the dispersal or vicariance models used to explain biogeographical patterns of related species in Colombia.

The tribe Diglottini Eichelbaum, 1909 comprises two halophilous rove beetle genera Diglotta Champion, 1899, and Paradiglotta Ashe & Ahn, 2004. The tribe contains eight known species distributed in the Nearctic and West-Palaearctic regions, and also Fiji Islands and New Zealand. This tribe is recorded for the first time from South America with the description of a new species, Diglotta brasiliensis n. sp. from southern Brazil (Paraná). Characters of the mouthparts, aedeagus and spermatheca of the new species are illustrated and compared with other Diglotta species. Sexual dimorphism is reported for the first time in the genus.

Amphipod species of the families Epimeriidae and Iphimediidae are recorded for the first time from Macquarie Ridge, asparsely sampled mid-ocean ridge between New Zealand and Antarctica. Epimeria ashleyi sp. nov. collected from twoseamounts on the Macquarie Ridge between 676–1025 m water depth is described in detail.Epimeria ashleyi sp. nov. can be distinguished from similar species by the unique combination of following charac-ters: pointed coxa 1–3, dorsal doublecarinae as well as three lateral projections on epimeral plates 1–3. The juveniles ofthe new species are described and are considerably different from the adults. Additionally, Labriphimedia pulchridentata(Stebbing, 1888), previously known only from Heard Island, is recorded from Macquarie Ridge seamounts with first images of its colour in life.

Three species of the genus Allocosa Banks, 1900 from southern South America are redescribed: Allocosa alticeps (Mello-Leitão, 1944), A. brasiliensis (Petrunkevitch, 1910) and A. senex (Mello-Leitão, 1945). The female of A. senex is described for the first time and the species is revalidated. A new species, A. marindia sp. nov. from southern Uruguay and southern Brazil is described. The new species is distinguished by the flattened terminal apophysis of the male bulb and the conspicuous pointed projections on the posterior margin of the female epigynum. The species inhabits in sandy estuarine and oceanic coasts with psammophile vegetation.

In this study, Erysimum nemrutdaghense Mutlu (Brassicaceae) is described as a new species from the province of Adıyaman in the South-east Anatolia. In order to determine the phylogenetic relationships of the new species, a portion of the nuclear ribosomal DNA sequences of ITS region was used. In addition to the new species, ITS regions of five Erysimum species were sequenced. Erysimum sintenisianum Bornm., E. lazistanicum (Rupr.) Lipsky, and E. stenophyllum Polatschek were sequenced in this study for the first time. The diagnostic morphological and phylogenetic characteristics are discussed with similar species. SEM images of trichomes on different parts of siliqua, stigma, and seed are given. Chromosome number of the new species is found to be 2n=16.

A New Species

The discovery of a new species of satyrine butterfly, Magneuptychia louisammour Benmesbah & Zacca, sp. n., that is phenotypically similar to a sympatric species widely known as Magneuptychia ocypete (Fabricius, 1776), led to a review of the taxonomic status of M. ocypete. A neotype for Papilio ocypete Fabricius, 1776 is designated and its redescription is provided. Neonympha sabina C. Felder & R. Felder, 1867 and Euptychia helle var. olivacea Aurivillius, 1929 are treated as junior subjective synonyms of P. ocypete and a lectotype is designated for each name. A neotype for the preoccupied name Papilio helle Cramer, 1779, and its replacement name Magneuptychia fugitiva Lamas, [1997], is also designated, and a redescription of this name and discussion of its taxonomic status are provided. We describe an additional phenotypically similar species, Magneuptychia kamel Benmesbah & Zacca, sp. n. from the western Amazon and raise the name Magneuptychia opima sheba Brévignon & Benmesbah, 2012 to species rank (stat. rev.) on the basis of morphological and DNA sequence evidence. We also discuss the difficulties regarding taxonomic and geographical delimitation in these complex species groups. Observations on Euptychiina behaviour are also provided. Finally, based on external characters and male genitalia, a proposed preliminary arrangement of two species groups is proposed, including other species of Magneuptychia Forster, 1964 and Cissia Doubleday, 1848.

The genus Metalibitia Roewer, 1912, is revised for the first time, and a cladistic analysis revealed that it is a monophyletic clade. This cosmetid harvestmen genus is restricted to open forests and adjacent vegetational formations in South America (humid Forest, being found mostly in the region of cerrado/chaco/pampas). An identification key for all known species is presented and a new species is described, Metalibitia abuna sp. nov. (type locality: Abunã, Porto Velho, Rondônia, Brazil). Two species, Paralibitia maculata Roewer, 1914 and Labrosa arenosa Mello-Leitão, 1939, are here synonymized under Metalibitia argentina (Sørensen, 1884).

Neoperlops gressitti Banks, 1939 is redescribed, and recorded from Guangxi Zhuang Autonomous Region for the first time. Neoperlops huanghuye (Chen, 2020) comb. n., recently described from Fujian Province from southeastern China, is transferred from Phanoperla Banks, 1938. The six species of the genus are classified in two groups of morphologically similar species.

The paper presents a taxonomic review of Bulbophyllum section Rhytionanthos for the flora of Vietnam and provides the key for its species’ identification. A new species, B. truongtamii and a new variety, B. taeniophyllum var. denticulatoalatum are described for science. Bulbophyllum nodosum is reported for the first time from the country. Bulbophyllum strigosum, described 20 years ago based on cultivated plant of uncertain origin was rediscovered in NE Vietnam. For this species, location and detailed description are reported. Analytical photos, data on phenology, ecology, and distribution are presented for all studied species. The morphological comparison table of the new species, new variety and newly recorded species segregating them from similar species are presented.
