The Empis (Coptophlebia) hyalipennis-group is redefined, keyed, cladistically analysed and three new species, Empis doi, sp. nov., Empis pseudohystrichopyga, sp. nov. and Empis pseudovillosipes, sp. nov., are described (from Thailand, China and Taiwan respectively). A cladistic analysis of 27 adult morphological characters was performed for Empis hyalipennis (the type-species of the subgenus Coptophlebia), and 13 Nearctic, Oriental and Palaearctic species hypothesised as being closely related, which resulted in a single tree of 31 steps (CI = 0.96; RI = 0.98). Monophyly of the group was established on the basis of two apomorphic characters of the male hypopygium. Based on these results and previous studies of the Empis-Coptophlebia complex of subgenera within the genus Empis, the E. (C.) hyalipennis-group appears to be much richer in species, exhibit greater morphological heterogeneity and be more widely distributed than expected. It is strongly recommended that any future revision of the subfamily Empidinae should apply the name Coptophlebia only to the monophyletic Empis (Coptophlebia) hyalipennis-group defined in this study.

Three New Species

The genus Thectochlora Moure has been treated as containing only a single species. Based on morphological characters, five species are here recognized: T. alaris (Vachal, 1904), the type-species of Thectochlora; T. basiatra (Strand, 1910) new combination, previously placed in Pseudaugochlora; and three new species, T. brachycera new species (Brazil and Guiana), T. hamata new species (Brazil and Uruguay) and T. mixta new species (Brazil). A male syntype of Augochloropsis (Pseudaugochloropsis) basiatra Strand, 1910, from Paraguay (Villa Morra), is here designated lectotype in order to stabilize the taxonomy of the group. The species of Thectochlora are distinguished based mainly in the males; females of T. alaris and T. basiatra were considered indistinguishable. An identification key, cladistic analysis, maps of geographic records and illustrations are presented.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

This study represents the first phylogenetic reconstruction of lumbrinerid genera using parsimony analyses of 38 morphological characters. Following higher-level phylogenetic analysis, Oenone (Oenonidae) was selected as outgroup. The analysis was restricted to type species for each genus, yielded 24 equally parsimonious trees, which after successive weighting were reduced to one tree (CI= 0.7396). The topology of this tree revealed the separation of the family into four main clades: 1. Lysarete, 2. Arabellonereis, 3. Scoletoma, Lumbrineris, Hilbigneris gen. nov., Kuwaita, Lumbricalus, Sergioneris gen. nov. and Eranno, and 4. Abyssoninoe, Cenogenus, Lumbrinerides, Lumbrineriopsis, Augeneria, Loboneris gen. nov., Gallardoneris gen. nov., Helmutneris gen. nov., and Gesaneris gen. nov.; the position of Ninoe is unclear. A diagnosis of each genus is provided, including the description of six new genera and three new species. A key to lumbrinerid genera is included.

Equal Weighting

The Neotropical thynnine genus Scotaena is revised and a cladistic analysis is presented. The analysis, conducted from 75 morphological characters of 31 terminal taxa, returned a single tree under equal weighting. The monophyly of Scotaena was not recovered. Three new genera and five new species are described: Kaysara gen. nov., Pseudoscotaena gen. nov. and Pampathynnus gen. nov., Scotaena reversa sp. nov., Kaysara laterolata sp. nov., Kaysara apiciconcava sp. nov., Kaysara marginoplicata sp. nov. and Kaysara levicrenata sp. nov. Three species are transferred to other genera as follows: Eucyrtothynnus rosenbergi (Turner, 1910) comb. nov., Glottynoides genisei Kimsey, 1991 comb. nov., Ornepetes clypearis Durán-Moya, 1941 comb. nov. Scotaena now comprises four species: S. trifasciata Klug, 1810; S. horni (Turner, 1927); S. vetusta Turner, 1909; and S. reversa. An identification key and geographical distribution maps for the studied species are also provided.

Three New Species

Spiders of the tropical Asian jumping spider genus Onomastus Simon, 1900 are small to medium-sized, delicate, translucent, commonly found inhabitants of Asian evergreen forest foliage. In this paper, three new species of the genus, O. jamestaylori sp. nov. (♂♀), O. corbetensis sp. nov. (♂♀) and O. maskeliya sp. nov. (♂♀) are described from Sri Lanka. The three new species are added to the matrix of a previous study to assess their phylogenetic position. The resulting cladistic analysis, based on 35 morphological characters from 18 taxa (13 Onomastus species and 5 outgroups) supports the monophyly of the genus. Additionally, a monophyletic, well-supported South Asian clade (India, Sri Lanka), which is restricted to the Sri Lanka-Western Ghats biodiversity hotspot, is recovered in most analysis. The three newly described species might be endangered due to their small population size and restricted distribution in high altitude cloud forest.

The eight species of Bicoxidens were studied in order to verify their taxonomic validity and determine the status of new material. Two new synonymies are established: B. grandis Lawrence, 1965 = B. matabele (Schubart, 1966) and B. flavicollis Attems, 1928 = B. nasti Mwabvu, 2000. B. polyptychus, incorrectly placed in Bicoxidens, on the basis of morphological characters, including gonopods, is moved to Brevitibius Attems, 1950. Three new species, B. matopoensis Mwabvu, B. nyathi Mwabvu and B. gokwensis Mwabvu are described. An identification key to the species, a phylogenetic analysis based on gonopod morphology and distribution data for each species are also presented

First Time

Abstract The phylogeny of the Oriental leafhopper genus Amritodus is reconstructed, for the first time, based on 47 discrete morphological characters and DNA sequence data from one nuclear and two mitochondrial genes. The phylogenetic results show that Amritodus is not monophyletic, and its concept is narrowed here to include four species: Amritodus atkinsoni, Amritodus brevis, Amritodus brevistylus and Amritodus saeedi. The phylogenetic results support establishment of a new genus, Paramritodus gen. nov., with three new species,Paramritodus triangulus sp. nov. (type species), Paramritodus introflexus sp. nov., Paramritodus spatiosus sp. nov. and three species previously included in Amritodus: Paramritodus pistacious comb. nov., Paramritodus flavocapitatus comb. nov. and Paramritodus podocarpus comb. nov. In addition, Amritodus flavoscutatus is transferred from Amritodus to Hyalinocerus as Hyalinocerus flavoscutatus comb. nov. Keys to species of Amritodus and Paramritodus are provided.

AbstractThe genus Alloclemensia n.gen. (type-species: Alloclemensia maculata n.sp.), with four species in the Palaearctic region and one species in the Nearctic region, is described and its species are revised. The genus comprises five species: mesospilella (Herrich-Schäffer) [= trimaculella (Herrich-Schäffer)], devotella (Rebel) [= muchei (Soffner), n.syn.] and three new species: americana from North America and unifasciata and maculata from Japan. The monophyly of the genus is demonstrated and the primary dichotomy within the genus is considered to lie between the two western Palaearctic species plus the North American species and the two eastern Palaearctic species. Keys to the species are provided and all species and their genitalia are described and illustrated. Two new combinations and one new synonymy are established and two lectotypes are designated.
