A New Species

Abstract A new species with a rounded tail belonging to the Enchodelus macrodorus-group is described from a natural habitat in the vicinity of Kaleibar City, north-west Iran. Enchodelus babakicus n. sp. is characterised by its medium sized body (1.21-1.56 mm), lip region offset by a marked constriction, odontostyle 40-45 μm long, tripartite uterus and presence of abundant males with 49-61 μm long spicules and 10-14 spaced ventromedian supplements. The new species is close to E. distinctus, E. groenlandicus, E. macrodorus, E. microdoroides and E. saxifragae. A population of E. macrodorus was also found in the same sample as the new species. Molecular analysis was inferred from sequencing of 18S rDNA and ITS1 regions of three species of the genus from Iran, including E. babakicus n. sp., E. macrodorus and E. veletensis, together with other available sequences in GenBank. The sequences showed that E. babakicus n. sp. belongs to a clade formed by Enchodelus species characterised by a rounded tail.

Summary A new species of Aporcelinus, collected in a natural habitat of central Mexico, is described and illustrated, including molecular (D2-D3 28S-rRNA) data. Aporcelinus zapotitlanensis sp. n. is characterised by its 1.19-1.43 mm long body, lip region offset by a deep constriction and 16.5-18.5 μm broad, odontostyle 19.5-22 long, neck 325-368 μm long, pharyngeal expansion 150-201 μm long or 46-55% of the total neck length, uterus 130-167 μm long and tripartite, V = 54-56, tail conical with finely rounded tip (30-37 μm, c = 34-43, c′ = 1.2-1.4) lacking a distinct dorsal concavity, spicules 48-51 μm long, and 11-12 spaced ventromedian supplements with one or two of them located within the range of the spicules. Molecular analyses confirm the monophyly of Aporcelinus and places the new species within a clade shared with A. infundibulicaudatus and A. amazonicus.

The Dactylosomatidae Jakowska and Negrelli, 1955 are one of four families belonging to adeleorinid coccidia and comprise the genera Babesiosoma Jakowska and Nigrelli, 1956 and Dactylosoma Labbé, 1894. These blood protozoa occur in peripheral blood of lower vertebrates, and are commonly reported parasitising amphibians. The present study describes Dactylosoma piperis n. sp. from the pepper frog Leptodactylus labyrinthicus (Spix, 1824) (Anura: Leptodactylidae), collected in 2018 at the municipality of Araguaiana, Mato Grosso State, Brazil, based on morphology of intra-erythrocytic trophozoite, primary and secondary merogonic stages and a molecular analysis (partial 18S rDNA). Dactylosoma piperis n. sp. forms a well-supported clade with other Dactylosomatidae. This is the first molecular characterization of a species of Dactylosoma from a Brazilian anuran.

About thirty years ago a species of manna, obtained from the Eucalyptus Mannifera, was brought from New South Wales, and was examined by Dr Thomas Thomson, and afterwards by Professor Johnston, both of whom ascertained it to contain a new species of sugar, different from the mannite which exists in ordinary manna. The author had, through the kindness of Mr Sheriff Cay, an opportunity of examining a very different species of manna, remarkable both from its chemical constitution, and from its possessing a definitely organised structure. This substance was discovered by Mr Robert Cay in 1844, in the interior of Australia Felix, to the north and north-west of Melbourne, where it occurs at certain seasons on the leaves of the Mallee plant, Eucalyptus Dumosa, and is known to the natives by the name of Lerp.

ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

A New Species

A new species in Megasporaceae, Aspiciliella pakistanica is described and illustrated from Pakistan. A comparative morpho–anatomical study and ITS–based molecular analysis confirmed its position within the recently resurrected genus Aspiciliella. The taxon is characterized by whitish–grey thalli having large and thick areoles without pale lines on the surface, and a discontinuous algal layer arranged in groups of vertical rows. Its positioning in a separate branch in the phylogenetic tree also makes it distinct from the other known species of the genus.

Five strains of the genus Coelastrella were studied from the collections of live cultures of algae of the Institute of Biology, Syktyvkar, Russia (SYKOA Ch-045-09, SYKOA Ch-047-11, SYKOA Ch-072-17) and the Siberian Institute of Plant Physiology and Biochemistry, Irkutsk, Russia (IRK-A 2, IRK-A 173). It was found that, despite their high morphological similarity, the strains have different phylogenetic relationships. The analysis of the 18S rDNA and ITS1-ITS2 showed that the studied strains belong to the species: C. terrestris (IRK-A 173), C. oocystiformis (SYKOA Ch-045-09; IRK-A 2) and C. aeroterrestrica (SYKOA Ch-047-11). The SYKOA Ch-072-17 strain is probably a new species for the genus. The results confirm the high phenotypic variability and hidden diversity among the representatives of this group of green algae.
