Two new species of the red algal genus Hypnea (Gigartinales) are described for the southeastern coast of Brazil based on three molecular markers (COI-5P, rbcL and UPA), detailed morphological analysis, and comparison with closely related species. These species were named H. wynnei Nauer, Cassano & M.C. Oliveira and H. yokoyana Nauer, Cassano & M.C. Oliveira. Hypnea wynnei is characterized primarily by its reduced size, sub-erect tufts with few lateral branches and entangled basal portion, a thallus that is flattened only at the apical portions, and tetrasporangial sori developed only at apical portions of the branchlets. Hypnea yokoyana is characterized by its larger thallus, profuse branching, entirely terete axes, larger diameter of the main axes, and lack of entangling at its base. The molecular data support the conclusion that H. wynnei and H. yokoyana are distinct from other Hypnea species and are distantly related to Hypnea from the Brazilian coast.

Abstract We used three molecular markers (COI-5P, rbcL and UPA) to investigate the diversity of Hypnea spp., an economically important red algal genus, collected from India. Our concatenated tree (COI-5P and rbcL) supported the monophyly of two new species, Hypnea indica sp. nov. and Hypnea bullata sp. nov. H. indica diverged from its closest two sister species, Hypnea cervicornis and Hypnea tenuis (by 15.9 and 11.2%, respectively, in COI-5P; and 3.4 and 3.2% in rbcL). We describe H. indica as a new species characterised by an erect, percurrent main axis with spine-like branchlets in acute angles, straight and forked apices, axial cells surrounded by large periaxial cells or two cells similar in size to the axial cell, and the presence of lenticular thickening in the cross-section of the thallus. H. bullata diverged from its closest sister species, Hypnea brasiliensis (by 10.9% in COI-5P and 3.3% in rbcL). H. bullata is characterized by a prostrate thallus up to 1.5 cm in height, highly anastomosed, with an axial cell surrounded by similar sized, or smaller, periaxial cells, tetrasporangia present near the base of branchlets, and the presence of lenticular thickening.

Two earthworm species from central Mexico are described: Protozapotecia acaxetlensis sp. nov. and Protozapotecia oya-metlensis sp. nov. Delimitation of species was supported by morphological and molecular evidence. The two new species differ from the other species of Protozapotecia by the position of the prostates in segments 18 and 20. This morphological characteristic relates them to the genus Diplocardia, from which they differ by the presence of two gizzards separated by a muscular septum (Protozapotecia), instead of two gizzards fused as one, separated by a thin membranous septum in intersegment 5/6 (Diplocardia).

Abstract The male genitalic characters of Hexapoda are well known for their great taxonomic and systematic value. Despite insect male genitalia displaying large diversity, variation, and modification across orders, some structures are consistently present, and such characters can serve as the basis for discussion regarding homology. In the order Lepidoptera, a male genitalic structure widely known as the ‘juxta’ is present in many taxa and absence or modification of this character can be phylogenetically informative at the generic or higher level. We here focus on the systematics of the so-called ‘Taygetis clade’ within the nymphalid subtribe Euptychiina, and report an unusual case of ‘juxta loss’ in a single species, Taygetina accacioi Nakahara & Freitas, n. sp., a new species from Brazil named and described herein. Additionally, we describe another west Amazonian Taygetina Forster, 1964 species, namely Taygetina brocki Lamas & Nakahara, n. sp., in order to better document the species diversity of Taygetina. Our most up-to-date comprehensive molecular phylogeny regarding ‘Taygetis clade’ recovered these two species as members of a monophyletic Taygetina, reinforcing the absence of juxta being a character state change occurring in a single lineage, resulting in an apomorphic condition, which we report here as a rare case in butterflies (Papilionoidea).

AbstractExamination of 122 specimens ofXanthogrammaSchiner, 1861 (Diptera: Syrphidae) from varied localities in Europe (+Turkey) resulted in the description of two new species (X. aeginaeRicarte, Nedeljković, and Vujićnew speciesandX. pilosumNedeljković, Ricarte, and Vujićnew species), as well as new data on six other species. Most of the examined material originated from the Balkan Peninsula and Greek islands. New species concepts were supported by morphological and molecular evidence. Relationships among the eight studied species were analysed and discussed based on the data of nuclear (ITS2) and mitochondrial (COI) genes sequences. An identification key to the European species ofXanthogrammais provided. Lectotypes are designated forDoros decoratumZetterstedt, 1843,Lasiophthicus novusRondani, 1857,Syrphus laetusFabricius, 1794,Syrphus ornatusMeigen, 1822, andXanthogramma nobilitatumFrey, 1946.

Two New Species

We describe two new species of green pitviper from Southeast Asia that are morphologically similar to Cryptelytrops macrops, but can be distinguished from that species by genetic means, multivariate analysis of morphology and some aspects of coloration. Cryptelytrops cardamomensis sp. nov., is described from southeastern Thailand and the Cardamom Mountains of southwestern Cambodia. Cryptelytrops rubeus sp. nov. has been recorded from southern Vietnam and eastern Cambodia. These species have previously been confused with C. macrops, hence we also present here a redescription of this species, whose range is now restricted to Thailand, southern and central Laos, and northeastern Cambodia. All three species are present in Cambodia, but have disjunct ranges corresponding to three separate highland regions in southwestern (Cardamom Mountains), northeastern (western edge of the Kontum Plateau) and eastern (low elevation hills on the western edge of the Langbian Plateau) Cambodia for C. cardamomensis, C. macrops and C. rubeus respectively. However, there is still considerable morphological variation between geographically separated populations of C. macrops s.s., and greater sampling in southern and northern Thailand in particular may be required before the species diversity of this group is fully clarified.

Gloiosaccion Harvey, with type G. brownii (Rhodymeniaceae, Rhodymeniales), is a red algal genus characterized by the presence of large, hollow and saccate vesicle-shaped thalli arising from small solid axes. Whereas Gloiosaccion has traditionally been viewed as being closely related to Botryocladia (Agardh) Kylin, a multi-marker phylogenetic analysis based on chloroplast-encoded rbcL and UPA and nuclear LSU rDNA sequences instead places Gloiosaccion brownii and G. pumila in the Chrysymenia clade that includes the generitype C. ventricosa (Lamouroux) J. Agardh. Gloiosaccion is reduced to synonymy with Chrysymenia J. Agardh, a taxonomic move first advocated by De Toni in 1900. In addition to C. brownii (Harvey) De Toni, “Gloiosaccion” brownii var. firmum Harvey and “G.” pumilum J. Agardh are recognized as the distinct species Chrysymenia coriacea comb. et stat. nov. and C. pumila (J. Agardh) Weber-van Bosse, respectively. A new species, C. pseudoventricosa sp. nov. is proposed to accommodate specimens going under the name C. ventricosa (J.V. Lamouroux) J. Agardh from the Gulf of Mexico and Caribbean Sea.
