The freshwater shrimp family Kakaducarididae Bruce, 1993 is revised and its familial status reappraised using morphological characters and the results of a complementary molecular study (Page et al. 2008). Based on combined morphological–molecular data, the Kakaducarididae is synonymised with the Palaemonidae Rafinesque, 1815 and the monotypic genus Kakaducaris Bruce, 1993 is synonymised with Leptopalaemon Bruce & Short, 1993. The Texan cave shrimp, Calathaemon holthuisi (Strenth, 1976), provisionally included in the Kakaducarididae by Bruce (1993), is re-assigned back to the Palaemonidae. Leptopalaemon is re-diagnosed and three new species, L. gibbosus, sp. nov., L. gudjangah, sp. nov. and L. magelensis, sp. nov., are described from the north-western edge of the Arnhem Land plateau/escarpment complex, Northern Territory, Australia. The two previously described species, L. gagadjui Bruce & Short, 1993 and L. glabrus (Bruce, 1993), comb. nov. are re-diagnosed. A key to the five presently recognised Leptopalaemon species is provided.

Three New Species

We consolidate and present data for the sexual stages of five North American species of Orphella, fungal members of trichomycetes previously classified within Harpellales. Three species emendations accommodate the newly recognized characters, including not only the coiled zygospores and accompanying cells but also other morphological traits not provided in the original descriptions for O. avalonensis, O. haysii, and O. hiemalis. We describe three new species, Orphella cataloochensis from both the Smoky Mountains in USA and two provinces in Canada as well as O. pseudoavalonensis and O. pseudohiemalis, both from the Cascade Range, in Oregon, USA. Key morphological features for all known species are summarized and reviewed, with illustrations of some of the North American taxa to update and supplement the literature. The entire suite of morphological characters is discussed, with emphasis on species relationships and hypotheses on possible vicariant origins. We also present a molecular phylogeny based on nuc rDNA 18S and 28S, which supports Orphella as a lineage distinct from Harpellales, and we establish a new order, Orphellales, for it. With the combination of sexual features, now known for 12 of the 14 species of Orphella, and new molecular data, the group is now better characterized, facilitating and hopefully also promoting future studies toward a better understanding of their relationships, origins, and evolutionary history as stonefly gut–dwelling fungi.

Two New Species

Two new species of the weevil genus Rhamphus from Italy are herein described: R. bavierai n. sp. (Sicily) and R. hampsicora n. sp. (Sardinia). Both are morphologically and from a molecular perspective close to R. oxyacanthae (Marsham, 1802) and R. monzinii Pesarini & Diotti, 2012. Aside from a diagnostic description and a synoptic key, distribution data and notes on the host plants of the four species are reported. Whereas R. monzinii can be distinguished by several morphological characters, the other three species are morphologically very similar to each other and separable only by the combination of a few subtle characters. On the contrary, a preliminary molecular study revealed substantial divergences of mtCOI from 6.2 to 14.9% between the species, confirming the importance of an integrative taxonomy.

Colour Dimorphism

Representatives of the Southeast Asian pholcid spider genus Uthina Simon, 1893 have been thought to be very homogeneous in their ecology and morphology. The 14 previously known species all inhabit near-ground microhabitats and cave entrances, and range from pale to dark brown in colour. Even their genitalia are partly very similar, with some species pairs being barely distinguishable based on morphological characters. Here we describe three new species from Bali, Java and Sulawesi that represent three further microhabitats and demonstrate considerable ecological and morphological diversity within the genus: U. maya, sp. nov. from Bali is a large dark species on tree trunks; U. hylobatea, sp. nov. from Bali and eastern Java is a pale leaf-dwelling species that exhibits colour dimorphism; and U. mimpi, sp. nov. is a pale troglomorphic species collected in the aphotic zones of two South Sulawesi caves. In addition, we present new data for five previously described species, including ultrastructure, natural history, new records, taxonomic notes and a description of the previously unknown female of Uthina khaosokensis Yao, Li & Jäger, 2014. Molecular data suggest that all previously described species are very closely related to each other (constituting the monophyletic luzonica-group), and that the three new species represent separate clades within the genus. However, the basal trichotomy could not be resolved: U. maya + (U. hylobatea + U. mimpi) + luzonica-group.

The genus Epexochus Reitter is revised, its morphological characters are defined and the differences from the most closely related genera, Leucochromus Motschulsky and Eurycleonus Bedel, are outlined. All the populations of Epexochus from Kazakhstan and north-western China (Xinjiang) are referred to a single species, E. lehmanni (Ménétries). The status of Exochus latus Chevrolat is discussed and its name is formally synonymised with lehmanni. According to Art. 45.6.4.1 of the ICZN (1999), the name lehmanni var. consobrinus Faust, originally proposed for a colour variant and misidentified by Ter-Minasyan, is deemed to be subspecific and thus a synonym of lehmanni. Three new species are described in the genus: E. korotyaevi sp. n. (type locality: southern Tajikistan, Shaar-tuz region), characterised by the pronotum curved towards the elytra and by slender, lanceolate scales; E. voriseki sp. n. (type locality: central Uzbekistan, Gazli), characterised by small size, only slightly convex elytra and long hair-like setae, and E. mongolicus sp. n. (type locality: western Mongolia, Kobdoskij Aimak), characterised by large size, convex elytra with flat intervals and an elongate lamella of the aedeagus.

We diagnose and describe three new species of the primitively segmented spider genus Songthela from Guizhou Province, China, based on morphological characters and molecular data: S. liuisp. nov. (♂♀), S. tianzhusp. nov. (♂♀), and S. yupingsp. nov. (♂♀). We provide the genetic distances within and among the three new species based on the DNA barcode gene, cytochrome c oxidase subunit I (COI) to support our descriptions. We also provide the COI GenBank accession codes for the three new species for future identification.

Three new species of the genus Dendronotus are described from the North Pacific waters of Japan and Russia. For the first time since 1949, three new species, D. jamsteci sp. nov., D. zakuro sp. nov. and D. bathyvela sp. nov. are described from the waters of the Japanese Islands. D. zakuro sp. nov. was also discovered in the waters of Russia (Kamchatka). The descriptions of the new species D. jamsteci sp. nov. and D. zakuro sp. nov. are based on morphological and molecular data; D. bathyvela sp. nov. morphologically belongs to the group of D. robustus, D. velifer and D. patricki. This study revises our knowledge of North Pacific species of the genus Dendronotus, considerably expands the number of species worldwide and contributes to the multilevel fine-scale diversity concept.

Three new species, Hyalopecten vityazi sp. nov., H. abyssalis sp. nov. and H. kurilensis sp. nov., are described from the abyssal and hadal zones of the North-western Pacific. Hyalopecten vityazi was found in the Kuril-Kamchatka and Aleutian trenches at 6090–8100 m depth. It is the most deep-water species of the order Pectinida. Hyalopecten abyssalis and H. kurilensis were found at the abyssal plain adjacent to the Kuril-Kamchatka and Aleutian trenches at 4550–5045 m depth. To date, 13 species of the genus Hyalopecten are known from different regions of the World Ocean. A table with the main differences among all known species in the genus is provided.

Three New Species

Abstract Bees of the tribes Biastini, Neolarrini, and Townsendiellini are cleptoparasites in the subfamily Nomadinae (Hymenoptera, Apidae) and parasitize solitary bees. Understanding their phylogenetic relationships has proven difficult for many decades. Previous research yielded ambiguous results because of conflicting phylogenetic signals of larval and adult morphological characters. Molecular data settled some of this disparity but our knowledge remains fragmented due to limited taxon sampling and the discovery of a new lineage associated with Biastini: the enigmatic Schwarzia Eardley, 2009. Schwarzia has unusual morphological features and seems transitional between previously established taxa. This puts limits on our ability to diagnose the groups, understand their antiquity and biogeography, and study the evolution of host-choice. To address this, we integrate phylogenomics and morphology to establish a fossil-calibrated phylogeny for the tribes Biastini, Neolarrini, and Townsendiellini. We show that Schwarzia is indeed closely related to Biastes Panzer, 1806, but Biastes itself is paraphyletic in respect to Neopasites Ashmead, 1898, and even Biastini is paraphyletic due to Townsendiella Crawford, 1916, which is sister to Rhopalolemma Roig-Alsina, 1991. To ensure monophyly, we lower Neopasites to subgeneric rank within Biastes and resurrect Melittoxena Morawitz, 1873 as a third subgenus. We then assess the diagnosability of different tribal concepts and establish an expanded tribe Neolarrini that includes Biastini and Townsendiellini as new synonyms for Neolarrini. Neolarrini in this new, expanded sense likely originated in the Nearctic in the mid-Eocene and is, as far we know, composed exclusively of parasites of oligolectic hosts. Lastly, our continued efforts to find the rare Schwarzia in Eastern Africa led to the discovery of three new species, which are described herein.
