The genus Sobasina Simon, 1898 (Araneae: Salticidae) from Pacific Islands is reviewed and its main diagnostic characters (internal structures of epigyne, body shape, palps) documented for all species in a comparative way. The systematic position of the genus is shown to be non-aligned to any major groups of Salticidae.

Omostropus rotundatus Clarke, 1973 from the Bale Mountains (Ethiopia) is transferred to the genus Harpalus Latreille, 1802. Since the name rotundatus was already used in the latter genus, the substitute name Harpalus clarkei Kataev et Schmidt, nom. nov. is proposed for Harpalus rotundatus (Clarke, 1973), comb. nov. (non Dejean, 1829; non Chaudoir, 1844). The diagnostic characters of Harpalus and Omostropus are discussed. Data on distribution and hind wing development of some additional Ethiopian species of Harpalina mostly from the Bale and Arsi Mountains are presented.

The genus Ludioctenus Fairmaire, 1893 hitherto included only L. cyprius (Baudi di Selve, 1871) from the eastern Mediterranean and L. pakistanicus Schimmel & Tarnawski, 2012 from Pakistan. Here, we describe L. afghanicus sp. nov. from the Nuristan Province in eastern Afghanistan. The distribution and morphological diversity of Ludioctenus is discussed, main diagnostic characters for all species are figured, and an identification key to the species of this genus is provided. Female pregenital segments and genitalia are figured for the first time for Ludioctenus, and the systematic position of this genus and its relatives is discussed.

Preliminary Classification

We assessed characters that could be used to differentiate ammocoetes of chestnut lamprey ( Ichthyomyzon castaneus Girard, 1858), northern brook lamprey ( Ichthyomyzon fossor Reighard and Cummins, 1916), and silver lamprey ( Ichthyomyzon unicuspis Hubbs and Trautman, 1937). We sampled ammocoetes of the three species from 25 streams around the Great Lakes. Existing genetic markers were used to identify chestnut lamprey for this study, but the lack of genetic markers for silver and northern brook lampreys forced our preliminary classification of these two species to be based on stream-specific catch records of adults. Comparison of ammocoete gonads was inconclusive as a technique to distinguish between these two species. Other characters examined (including pigmentation patterns, morphometric characters, body shape, and myomere counts) varied significantly among species, but were inadequate for use as diagnostic characters because of high intraspecific variation and overlapping ranges. Chestnut lamprey ammocoetes were sometimes distinguishable by their pigmented lateral line organs, but this character was not always apparent. The lack of distinguishing characteristics makes existing taxonomic keys misleading for identifying Ichthyomyzon lamprey larvae.

A new species, Toccolus javanensis sp. nova, is described from a rainforest in Gunung Puncak, western Java, Indonesia. It is the fourth species of the genus, which was hitherto known only from continental SE Asia. It possesses a low ocularium and general body shape strongly resembling Dino weberi Loman from Sumatra. The relationships of Toccolus are discussed and the closely related genus Dino Loman is transferred from Podoctinae (Podoctidae) to Epedaninae (Epedanidae).

A comparative study of the larval morphology and biology of Arthrolytus glandium Bouček, Cecidostiba fungosa Geof-froy in Fourcroy, Cecidostiba geganius (Walker), Pteromalus bedeguaris (Thomson), Pteromalus hieracii (Thomson),Pteromalus isarchus Walker, Rivasia fumariae Askew & Nieves-Aldrey and Stinoplus lapsanae Graham (Pteromalidae)is presented. These eight species are all parasitoids of gall wasps in Europe and are components of communities associatedwith different gall-wasp food guilds: galls on herbs, shrubs and oaks. Special attention was paid to larval body shape, headcapsule characters, the mouthparts and especially the mandibles and the chaetotaxy of the head. Diagnostic characters ofthe genera are provided and except for R. fumariae the terminal instar larvae of all studied species are described and illus-trated for the first time with scanning electron photomicrographs. Information on the biology of each species, including new rearing records, is given.

AbstractThe monophyly of the Yponomeutoidea is demonstrated by a single autapomorphy, the presence of pleural lobes on 8th abdominal segment in the male. The taxonomic history of the superfamily is reviewed and the diagnostic characters listed. Fifteen informal suprageneric groups are included pending a phylogenetic reclassification of the superfamily. The groups are indicated by the most prominent genus contained in each: Acrolepia Curtis, Argyresthia Hübner, Atteva Walker, Bedellia Stainton, Glyphipterix Hübner, Heliodines Stainton, Leucoptera Hübner, Lyonetia Hübner, Ochsenheimeria Hübner, Orthotaelia Stephens, Plutella Schrank, Prays Hübner, Scythropia Hübner, Yponomeuta Latreille and Ypsolopha Latreille. For each group autapomorphies and a tentative list of included nominal genera are given. The diagnostic characters of the genus groups are tabulated. The Ochsenheimeriidae and Lyonetiidae (with subfamilies Bedelliinae and Cemiostominae) are assigned to the Yponomeutoidea. Family group taxa excluded from the Yponomeutoidea after the year 1970 are reviewed. The Douglasiidae are excluded from the Yponomeutoidea and allocated to the Tineoidea. The Bucculatricidae, often included as subfamily in the Lyonetiidae, belong to the Tineoidea. Four genus groups, the Homadaula, Lucturu, Schreckensteinia and Urodus groups, are discussed and excluded from the Yponomeutoidea. Their exact systematic position needs further study.

Diagnostic Characters

A new genus and species of Keroplatidae (Diptera), Langkawiana maculata gen. et sp.n., is described and its systematic position is discussed. The description is based on a male collected at Langkawi Island (Malaysia). Diagnostic characters of the new genus are as follows: the absence of ocelli, membraneous area around cerebral sclerite continues behind compound eyes, both orbital sclerite and frons well developed, short palpomeres, wings with dark bands, relatively long radio-median fusion, tibial trichia arranged in regular rows, reduced spurs on mid and hind tibia, and details on male terminalia. A new phylogenetic analysis of the tribe Robsonomyiini is proposed and a key to genera is presented.

Distribution of flightless insect lineages often help us to identify the areas of long-term stability which serve as biodiversity hotspots. In this paper we taxonomically revise the wingless click-beetle genus Neodima Schimmel & Platia, 1992 endemic to the mountainous regions of Sichuan, China. Neodima sichuanensis Schimmel & Platia, 1992 and N. cechovskyi Schimmel, 1998 are redescribed, and N. belousovi Prosvirov & Kundrata sp. nov. is described as new for science. The distribution and morphological diversity of Neodima is discussed, main diagnostic characters for all species are figured, and an identification key to the species of this genus is provided. Mouthparts as well as female pregenital segments and genitalia are described and figured for the first time for this genus. Further, we compare Neodima to morphologically similar genera, and discuss its systematic position within Dimini.

The paper presents comparison of main diagnostic characters of all recognizable species of genera Euophrys C.L. Koch, 1834, Pseudeuophrys Dahl, 1912 and Talavera Peckham & Peckham, 1909, also delimiting new genus Euochin from China. All that purports to illustrate the current state of classification suggests progress and improvements. Discussed postulates include adding color macrophotograps of live specimens to the routine tools of research, and routine use of precisely documented palps and internal structures of epigyne. Implementation of the above will require change of research protocol of all Salticidae, the conclusions drawn are applicable to studies of other families of spiders. New taxa described. Gen.

A New Species

In the headwaters of several small streams of Zijin hill (Nanjing City) we found a new species of the genus Caenis. Herein this species is illustrated and described as Caenis pycnacantha sp. nov. Its main diagnostic characters include: in nymphs, it has “normal” body shape, each femur has a dark brown subapical marking, and the maxillary palpi have relatively long apical segments. In adults, the forceps have dense setae on the surface and four large spines at the apex and the antennae have a slightly expanded base of the flagellum.
