European Lepidocyrtus species are usually grouped into five species-groups within two subgenera, Lepidocyrtus s.s. and Lanocyrtus, defined by the distribution of scale covering and dorsal head and body macrochaetotaxy. The discovery of several Lepidocyrtus populations with morphological characters intermediate between two species-groups suggested the need for the present study to test whether molecular data provide support to these groups. The morphology and gene sequences of 110 specimens belonging to 19 species of European Lepidocyrtus have been studied. Our molecular results are congruent with the distribution of the European species into the five groups established in the literature on the basis of morphological characters, but also indicated that subgenus Lanocyrtus is paraphyletic while subgenus Lepidocyrtus s.s. is monophyletic. A new species, Lepidocyrtus intermedius, is described, and a redefinition of European species-groups is proposed based on chaetotaxy.

Heimioporus sinensis, collected from tropical and subtropical areas of China, is introduced as a new species based on both morphological characters and molecular data. The species is characterized by the purplish red to deep magenta pileus, the reticulated stipe, the irregularly reticulate to reticulate-alveolate basidiospores 11.5–13.5 × 8–9.5 μm, and a trichodermal to intricately trichodermal pileipellis. Phylogenetic analyses based on the nuc 28S rDNA D1-D2 domains (28S) and the translation elongation factor 1-α gene (tef1-α) showed that H. sinensis is a distinct member of the genus Heimioporus in the subfamily Xerocomoideae.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

A new species of the Malagasy genus Dolurgocleptes Schedl, 1965 is described and illustrated. This is the second species known for the genus, which is restricted to the montane rainforests of north-eastern Madagascar. Dolurgocleptes is transferred from the tribe Dryocoetini to Polygraphini and placed near Polygraphus Erichson, based on examination of internal and external morphological characters and molecular data from Elongation Factor-1α and Cytochrome Oxidase I.

A new species of the Gekko japonicus group is described from Khammouane Province, central Laos, based on morphological characters and molecular data. Morphologically, Gekko nadenensis sp. nov. is differentiated from the remaining congeners by a combination of the following characters: size moderate (SVL 61.0–77.1 mm); nares bordered with rostral; internasals absent; postmentals enlarged; interorbital scales between anterior corners of the eyes 28–30; dorsal tubercles absent; ventral scales between mental and cloacal slit 175–185; midbody scale rows 123–140; ventral scale rows 38–40; subdigital lamellae on first toes 13–15, on fourth toes 14–16; finger and toe webbing present at base; tubercles on dorsal surface of fore and hind limbs absent; precloacal pores six (3+3 or 5+1) in a discontinuous row in males, absent in the female; postcloacal tubercles 1 or 2; tubercles absent on dorsal surface of tail base; subcaudals distinctly enlarged; dorsal surface of body with greyish brown blotches. Molecular analyses demonstrated the new species is closely related to G. bonkowskii and G. thakhekensis, but separated from them by approximately 7% in genetic divergence as shown by a fragment of the mitochondrial ND2 gene.

A new species of the family Agnaridae, Lucasioides altaicus sp. nov., is described from the Altai Mountains, southwestern Siberia, based both on morphological characters and molecular data. This species is the first record of Lucasioides from Russia, whose location is the northernmost habitat of terrestrial isopods in indigenous habitats presently known to Eurasia. The diagnostic characters of the new species and a preliminary phylogenetic analysis within Agnaridae are provided.

The taxonomy of the Allium saxatile group (sect. Oreiprason) has been studied recently upon morphological and molecular data. New specimens collected from the European part of Turkey near the Istranca Mountains and identified as ‘A. saxatile’ proved to be a new species confirmed by sequences of internal transcribed spacer (ITS) and two plastid DNA regions (rpl32–trnL and trnL–trnF) and supported by morphological characters. Allium urusakiorum, a new species from the A. saxatile group, is described here through living and herbarium specimens. It is the only species of the sect. Oreiprason in the country and seems to be an endemic species of the Turkish flora. Characteristics of the species include morphological description, identification key, molecular dataset, and karyotype (2n = 16).

Morphological characters support the description of a new species of Passifloraceae from Mayotte Island: Adenia barthelatii M. Pignal, Yockteng, Hearn & Labat. Morphological and molecular data suggest that A. barthelatii belongs to the ‘warty-gland’ subclade of Clade V defined by Hearn elsewhere. Since the warty-gland clade is restricted to the Malagasy region we suggest a Malagasy origin of this Maorian species of Adenia.

The male and female imago (subimago of both sexes unknown), and larva of a new species belonging to the Baetis buceratus species-group, namely Baetis (Baetis) zdenkae sp. nov. from Rhodos Island are described and illustrated in detail. Substantial diagnostic characters of males and larvae of the whole B. buceratus species-group are summarized and its position relative to other species groups is discussed. Critical characters distinguishing B. zdenkae sp. nov. from all other representatives of the B. buceratus species-group are emphasized and a discussion of 22 characters of the remaining 6 European species-groups of the subgenus Baetis Leach, 1815 s. str. and their relationships is offered. Available data on the biology of B. zdenkae sp. nov. (vertical distribution, habitat, current and substrate preference, abundance and density, possible life cycle type, and mating flight and oviposition patterns) and distribution with respect to possible endemism are given. Basic data on biology and area of distribution of Westpalaearctic species Baetis (Baetis) buceratus Eaton, 1870, B. (B.) nexus Navás, 1918 and B. (B.) spei Thomas & Dia, 1985 known only from Lebanon are summarized and compared to those of B. zdenkae sp. nov.
