Larvae of all instars of Dromica (s. str.) kolbei (W. Horn, 1897), D. (s. str.) alboclavata Dokhtouroff, 1883 and instar I of D. (s. str.) helleri (W. Horn, 1897) are described and figured in detail. The larvae of these species have several unique morphological characters. The shape of the pronotum, appendages of abdominal segment V and the peculiarities of chaetotaxy are of taxonomic importance. The main diagnostic characters to separate these species from each other and from other known Dromica larvae are given and discussed. Some bionomical peculiarities of D. (s. str.) kolbei are presented.

AbstractWe analyzed the phylogenetic relationships between eight Aphidius Nees and six Lysaphidus Smith species on the basis of 12 morphological characters by parsimony analysis. The consensus tree does not support the generic status of Lysaphidus. Aphidius iranicus, sp. nov., associated with Titanosiphon bellicosum Nevsky on Artemisia absinthium L. from Iran, is described. The new parasitoid species is described and illustrated by line drawings, and its diagnostic characters are discussed. The taxonomic position of the subgenus Tremblayia Tizado and Núñez-Pérez is also considered. Tremblayia and Lysaphidus are newly classified as synonyms of Aphidius. The following new or revised combinations are proposed: Aphidius adelocarinus Smith, comb. rev., A. ramythirus Smith, comb. rev., A. rosaphidis Smith, comb. rev., A. viaticus (Sedlag), comb. nov., A. arvensis (Starý), comb. nov., and A. erysimi (Starý), comb. nov.

1. The main facts in Brasil's (1907) account of the intracellular schizogony inSelenidium caulleryifromProtula tubulariahave been confirmed. Early stages in the sporogony of this species are described now for the first time.2. Intracellular schizogony is described for the first time inSelenidium mesniliBrasil fromMyxicola infundibulum, and here also the early stages in sporogony are noted for the first time.3. The life histories of Caullery and Mesnil's two unnamed species ofSelenidium(now calledS. spionis(Köll.) andS. foliatumn.sp.) fromScolelepis fuliginosahave been exhaustively studied. No schizogonic phase has been observed in either. The gametocysts, here described for the first time, are found to develop fully only after escape into the sea. The gametocysts ofS. spionisare ovoid, 108μ x 60μ and contain spores with four sporozoites: those ofS. foliatumare spherical, 70μ in diameter, and their spores contain eight sporozoites.4. New or hitherto little known species ofSelenidiumare recorded fromCirratulus cirratusMüll.,Branchiomma vesiculosumMont.,Sabella pavoninaSav.,Pomatoceros triqueterL. andTerebella lepidoriaKühl, and the morphological characters of the trophozoites are described.5. A discussion follows of the value of the diagnostic characters of the genusSelenidium. It is suggested that this genus requires drastic revision and will probably have to be dismembered. Stress is laid, however, on the occurrence in all the gregarines examined, and at all the observed stages of their development, of characteristic chromatic bodies at the anterior end, structures which have hitherto escaped the notice of most observers.

The subfamily Panchaetothripinae comprises 40 extant genera worldwide (ThripsWiki 2019), although only 15 genera are previously recorded from China (Mirab-balou et al. 2016; Li et al. 2018). Panchaetothripinae thrips are characterized by the strong reticulations on the body and leg. Wilson (1975) recognized three tribes in this subfamily, Panchaetothripini, Monilothripini and Tryphactothripini, but only tribe Tryphactothripini was relatively supported based on morphological characters (Mound et al. 2001). Species in this Tribe have abdominal segment II constricted at the base and bearing laterally patches of strong ridges, wart-like tubercles or stoutly recurved microtrichia, and abdominal segment X tends to be asymmetrical. Recently, two further genera of Tryphactothripini were found in Southern China, Noathrips and Opimothrips. These two monotypic genera are reported only from the Old World tropics, Noathrips from India and Sri Lanka, and Opimothrips only from Thailand (Bhatti 1967; Kudô 1979; Nonaka & Okajima 1992). The purpose of this paper is to record these two genera from China, together with the first description of the male of Opimothrips tubulatus.

The phenotypic variation of Thaumatomyia notate (Meigen, 1830) (Chloropidae) collected from six different regions was studied in the East Azerbaijan province in northwestern Iran during 2009-2012. Eight populations of Thaumatomyia notata with different phenotypes were recognized. Environmental parameters such as temperature, elevation and habitat were examined. The results of this study show that colour variation in T. notata is caused mostly by seasonal temperature, dark coloration in April to light in July. In addition, variation in some morphological characters such as antenna, ocellar triangle, microchaetotaxy and size as well as diagnostic characters and photos of each variation are provided.

Euphorbia otjipembana was hitherto only known from the type locality within the Kaokoveld Centre of Endemism, northwestern Namibia. Subsequently several additional populations were discovered, allowing for an amplified description of the species and the recognition of two subspecies. Euphorbia otjipembana subsp. okakoraensis, here described as a new subspecies, is only known from a small area within the Kaokoveld Centre. Diagnostic characters for subsp. okakoraensis include a shrubby habit and medium (up to 1 m) height, 5–7-angled, scarcely constricted branches with two pairs of spines per node and single cymes comprising of three horizontally arranged cyathia. A key as well as a comparative table with diagnostic morphological characters to distinguish between the two subspecies of E. otjipembana is provided.

Eleven Species

A revision of the Australian taxa of the genus Spergularia (Caryophyllaceae) on the basis of herbarium material, field studies and analysis of morphological characters necessitates realignment of some taxa and application of some neglected names, clarifying circumscription and understanding of the species of this genus. Eleven species are here recognised, with five considered indigenous, Spergularia nesophila and S. diandroides described as new and S. tasmanica transferred to Spergularia from Lepigonum. Fruits and seeds provide compelling diagnostic characters in this genus and are used in supplementary dichotomous and tabular diagnostic keys. Scanning electron micrographs (SEMs) illustrate key seed shape and surface features.

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.

Growth And Reproduction

The objectives of this study were to assess population biology and dynamics of the squat lobster Galathea intermedia. On the basis of nearly regular monthly samples taken with a 2-m beam trawl in the Helgoland trench (HTR) during the period of 1985 until 1992, sex ratio, length composition, relative growth and reproduction were studied. The overall sex ratio deviates significantly from 1:1 with 1[male ]:1·8[female] (P[les ]0·001). On average, sexes are equally large, but adult females attain a slightly larger size than adult males. No sex-specific differences in the length–weight relationship were found. Relative growth of the first abdominal segment is clearly of sexual-dimorphic character. On the basis of the length–frequency distributions, the life cycle of the HTR population lasts between one and two years. According to the appearance of ovigerous females and juveniles, reproduction and recruitment are clearly seasonal. Recruitment takes place between July and December. The main reproduction begins in April and ends in September, with a peak between June and August. A significant increase of specimens showing both male and female morphological characters, referred to as morphological hermaphrodites (P[les ]0·001), and males (P[les ]0·05) respectively, was detected.

For the first time, micromorphology structure of seeds in 10 species (L. annuus, L. cicera, L. hirsutus, L. tuberosus, L. miniatus, L. pratensis, L. laxiflorus, L. aphaca, L. nissolia, L. sphaericus) belonging to sections (Lathyrus, Pratensis, Aphaca, Nissolia, Linearicarpus) of Lathyrus L. collected from various regions of Azerbaijan were analysed. Seed samples of 10 species were taken for analysis from different biotopes and different populations located away from one-another. Collected seed materials were gathered in special sterile paper bags and their moisture was dried with silicagel substance in laboratory conditions. During the research, morphological characters, as well as general shape, size and colour of seed, length and width of hilum were identified under Leica EZ4D stereomicroscope. The largest seeds have been measured in Lathyrus (L. cicera 4,4–5,0 mm) section and the smallest seeds in Nissolia (L. nissolia 1,8–2,3 mm) section. The longest hilum belongs to L. miniatus 1,8–2,8 mm and the smallest in L. Nissolia 0,4–0,7 mm. The width hilum was measured in L. annuus (0,7–1,0 mm) and the narrow hilum L. nissolia (0,1–0,3 mm). Mature seed (2–3) samples were selected from each type under the SEM, the seeds were placed on stools with double-sided adhesive tapes and covered with gold powder through the JEOL JFC1600 ion-spray device for 1 to 2 minutes. Seed samples were researched on the side surface. The photos of the surface of seeds were taken in a 3000× size in JEOL JSM6610 lv electronic microscope, and structural analysis of the different places of their surfaces was conducted. The results showed that the microscopic research of the surface of seed is of taxonomic importance and is used in specification of the status of sections. The morphological properties such as surface structure, hilum length and width, papillae features can be used to differentiate some sections and species, but seed size, general shape seed and hilum, seed colour are not characteristics can be used to differentiate some sections.
