AbstractTwo new species of egg parasitoids, Oobius saimaensis Yao and Mottern new species and Oobius fleischeri Yao and Duan new species (Hymenoptera: Encyrtidae), are described from eggs of Agrilus fleischeri Obenberger, 1925 (Coleoptera: Buprestidae). Agrilus fleischeri is a phloem-feeding woodborer of poplar (Populus Linnaeus; Salicaceae) in northeastern China. These two species can be distinguished morphologically as O. fleischeri has five tarsomeres and O. saimaensis has four tarsomeres. Although O. saimaensis is morphologically similar to its sympatric congener O. agrili Zhang and Hang, 2005, an important natural enemy of the invasive emerald ash borer, Agrilus planipennis Fairmaire, 1888, molecular phylogenetics and morphological data indicate that they are distinct species. Phylogenetic relationships among the new species and other closely related species are also inferred by using DNA sequence data from several ribosomal and mitochondrial genes. In addition, we expand the known distribution of Oobius primorskyensis Yao and Duan, 2016 to include South Korea.

Unclear boundaries between species hinder identification in the field and in herbaria, especially in species groups that can only be distinguished on the basis of subtle morphological and ecological features. One such taxon is Ficinia indica, widespread in the Greater Cape Floristic Region, growing on deep sandy soils between sea level and 1000 m elevation. Within its range, several phylogenetically related and morphologically similar species co-occur or occupy distinct habitats. Studies in herbaria show species in the Ficinia indica complex to be largely misidentified based on the use of qualitative information. Here, we investigate whether the six taxa recognized, based on one or a few characters, are supported as distinct species based on multivariate analysis of macro-morphological data. Two of the taxa were mostly separated whereas the other four taxa overlapped in multivariate space, but all the taxa could be distinguished using a single or a combination of morphological and ecological characters. We uphold the four previously recognized taxa (Ficinia argyropus, F. elatior, F. indica, F. laevis) as species, describe two new species (F. arnoldii and F. montana), and provide a dichotomous key for their identification.

The Genera of Fungi series, of which this is the sixth contribution, links type species of fungal genera to their morphology and DNA sequence data. Five genera of microfungi are treated in this study, with new species introduced in Arthrographis, Melnikomyces, and Verruconis. The genus Thysanorea is emended and two new species and nine combinations are proposed. Kramasamuha sibika, the type species of the genus, is provided with DNA sequence data for first time and shown to be a member of Helminthosphaeriaceae (Sordariomycetes). Aureoconidiella is introduced as a new genus representing a new lineage in the Dothideomycetes.

Eupholidoptera karatolosi Mofidi-Neyestanak & Quicke from Greece and E. mirzayani Mofidi-Neyestanak & Quicke from Iran, two new species of bushcrickets (Orthoptera, Tettigoniidae: Platycleidini), are described and distinguished from closely related species based on morphology. Species relationships within Eupholidoptera Maran are discussed and some species are given new assignments. A simplified illustrated identification key to the species of Eupholidoptera is provided to accommodate the new species. They are being described since they have been used to generate DNA sequence data that will be published elsewhere as part of a phylogenetic study of the tribe Platycleidini.

Two new species of Sri Lankan shrub frogs of the genus Pseudophilautus are described. These species are diagnosed from their congeners on the basis of morphology, morphometrics and mitochondrial DNA sequence data. Pseudophilautus schneideri, new species, is distinguished from all Sri Lankan Pseudophilautus by its small size (< 22.8 mm SVL), distinct tympanum and supratympanic fold, sharp canthal edges, granular throat, chest and belly, and absence or presence of a vomerine ridge. Pseudophilautus hankeni, new species, is distinguished by its diminutive size (< 21.9 mm SVL), distinct tympanum, rounded canthal edges, tuberculated outer edge of lower arm, tuberculated dermal fold on outer edge of foot, granular throat, chest and belly, and the absence of a vomerine ridge. Pseudophilautus schneideri inhabits shrubs in open areas of the low to mid-elevations of the island’s south-western ‘wet zone’ (rainfall > 2,000 mm•yr -1 ), including anthropogenic habitats, while P. hankeni is found on shrubs in the understorey of montane forests of the highest peaks (c. 1,200– 1,600 m elevation) of the Knuckles region. These descriptions bring the total number of valid species of Sri Lankan Pseudophilautus to 67, 48 of which are extant.

A new species of the eyeless eleotrid genus Milyeringa is described from wells sunk on Barrow Island, Western Australia. Milyeringa justitia n. sp. is the third species of the genus to be named. Morphological data and cytochrome c oxidase subunit I (COI) DNA sequence data from a wide sample of localities at which the genus occurs was used to evaluate relationships and species limits. Milyeringa veritas is redescribed, and M. brooksi is synonymised with M. veritas. The unique form and ecology of these fishes, plus the threats to their survival, warrants immediate and continuing attention in management.

Two new species of the doryctine genus Iare, I. mexicanus sp. nov. and I. cheguevarai sp. nov., are genetically and morphologically described from a tropical dry forest in Jalisco, Mexico. Iare belokobylskiji Marsh is also reported for the latter region. These species represent the northernmost distribution records for the genus. A simultaneous Bayesian analysis with COI and 28S DNA sequence data recovered the three examined species of Iare within a single clade, though with low support. This genus appears nested within a large doryctine Neotropical clade as sister group of a cluster containing species of Callihormius Ashmead, Leluthia Cameron, Histeromeroides Marsh and Panama Marsh.

A new species in the dicroglossine genus Limnonectes from West Sumatra, Indonesia, is described. Analysis of DNA sequence data from the mitochondrial 12S and 16S gene regions places the species within the Limnonectes kuhlii Complex and demonstrates it to be the sister taxon of Limnonectes kuhlii sensu stricto from Java. Both molecular and morphological data support the recognition of this lineage as a new species. Notably, the presence of a spinule-covered mental plate distinguishes Limnonectes sisikdagu sp. nov. from all other members of the L. kuhlii Complex. Additionally, pair-wise sequence divergence greater than 10% separate the new species from its sister taxon, L. kuhlii from Java.

Alternate asexual and sexual generations are described for four species, Andricus archboldi Melika & Abrahamson, sp. nov., A. fitzpatricki Melika & Abrahamson, sp. nov., A. schickae Nicholls, Melika & Stone, sp. nov., Neuroterus aliceae Melika, Nicholls & Stone, sp. nov..

All taxa are supported by morphological data; matching of generations is established using DNA sequence data. We also demonstrate that Neuroterus niger var. alimas Kinsey should be considered as a nomen dubium.
