Allopatric alpine populations of Phtheochroa frigidana s. lat. (Lepidoptera, Tortricidae) are reviewed. In addition to traditional diagnostic characters of external morphology, the genitalia structures of everted vesicae in male genitalia and DNA barcodes are analysed. This new approach supports the existence of five rather than two species in Europe: Phtheochroa schawerdae (Rebel, 1908) comb. nov. (Dinaric Mts, Rila Mts, Pirin Mts) = P. drenowskyi (Rebel, 1916) syn. nov.; P. alpinana sp. nov. (SW Alps); P. apenninana sp. nov. (Apennines); P. frigidana (Guenée, 1845) stat. rev. (Pyrenees) = P. flavidana (Guenée, 1845) = P. sulphurana (Guenée, 1845) = P. andorrana (Millière, 1865); P. cantabriana sp. nov. (Cantabrian Mts). In order to stabilize the nomenclature, a neotype for Eupoecilia frigidana is designated.
Phlyctinus callosus (Schoenherr, 1826) (Curculionidae, Entiminae, Oosomini) is a species native to the Western Cape province of the Republic of South Africa. It is regarded as a key pest of orchards and vineyards. Detailed observations of its morphology and ecology have shown this species to be a complex of closely related species. In this study we describe the species of this complex, provide morphological and molecular diagnostic tools to distinguish between species, and review their distribution and host plant associations. In all, six species are recognized in the P. callosus complex and five are described as new (P. grootbosensis Haran sp. nov., P. xerophilus Haran sp. nov., P. planithorax Haran sp. nov., P. littoralis Haran sp. nov., P. aloevorus Haran sp. nov.). Sequences of the mitochondrial gene used (cytochrome oxidase I, COI) indicated that P. xerophilus Haran sp. nov. might comprise several cryptic species for which stable morphological features could not be identified at this stage. The species of the genus Phlyctinus appear to be primarily associated with various Asteraceae found in humid, sandy and disturbed habitats.
In this paper we describe two new tardigrade species belonging to the Macrobiotus hufelandi complex: Macrobiotus noongaris sp. nov. from Perth, Australia, and Macrobiotus kamilae sp. nov. from Mussoorie, India. Live specimens extracted from moss samples were used to establish laboratory cultures in order to obtain additional animals and eggs needed for their integrative descriptions. These descriptions are based on traditional morphological and morphometric data collected using both light and scanning electron microscopy, which, at the same time, were associated with DNA sequences of four genetic markers, three nuclear (18S rRNA, 28S rRNA and ITS-2) and one mitochondrial (COI). The use of DNA sequences allowed for a more accurate verification of the taxonomic status of M. noongaris sp. nov. and M. kamilae sp. nov as independent species of the hufelandi group. Although they both exhibit typical inverted goblet-shaped processes, they represent a recently discovered clade, which was thought to group species with modified morphology of egg processes. Thus, this contribution expands the definition of the mentioned clade and constitutes another link that will be helpful for future studies on the evolution of the M. hufelandi complex.
