A STUDY ON MINDARUS KOCH IN CHINA WITH DESCRIPTIONS OF NEW SPECIES AND NEW SUBSPECIES (HOMOPTERA: MIN-DARIDAE)*

Abstract This paper deals with the genus Mindam Koch from China. The phylogeny of the genus is discussed. M. keteleerifoliae is regarded as the most advanced species, M. obliquus and M. piceasuc-tus are more advanced than M. abietinus, M. japonicus and M. victoria. The origin centre of the genus may be in Europe and the differentiation centre of the genus may be in Hengduan Mountains Region of China. Geological distribution of the genus shows island-shaped pattern. Five species from China was described in this paper, including one new species, M. piceasuctus Zhang and Qiao, one new subspecies, M. abietinus triprimesensori Zhang and Qiao and one newly recorded species, M. abietinus abietinus Koch 1856. A key to the Chinese species of Mindarus is given. The specimens of five species from China are deposited in the Institute of Zoology, Academia Sinica.

New information on host plants and distribution ranges of an invasive gall midge, <Emphasis Type="Italic">Contarinia maculipennis</Emphasis> (Diptera: Cecidomyiidae), and its congeners in Japan

Gall midges of the genus Contarinia (Diptera: Cecidomyiidae) that infest the flower buds of various plant species have been newly found in Japan in recent years. Those infesting the flower buds of Pseuderanthemum laxiflorum (A. Gray) Hubbard ex Baillon (Amaranthaceae) and Jasminum sambac (Linnaeus) Aiton (Oleaceae) in Okinawa Prefecture, and Dendrobium spp. (Orchidaceae) in Mie Prefecture were identified, on the basis of morphological features and molecular information, as an invasive gall midge, C. maculipennis Felt. C. maculipennis was recorded in Mie Prefecture for the first time, and P. laxiflorum is newly regarded as one of the host plants of C. maculipennis. Three other Contarinia gall midges that we found infesting the flower buds of Lycopersicon esculentum Miller, Capsicum annuum Linnaeus (Solanaceae), and Oxalis corniculata Linnaeus (Oxalidaceae) were not identical with C. maculipennis. Among these, the first two, which infested solanaceous plants, were identical. However, the species other than C. maculipennis could not be identified to the species level because morphological differences were obscure and DNA sequencing data of allied congeners have not yet been registered on GenBank.     

Phenetic relationships of six species of mullets (<Emphasis Type="Italic">Mugilidae</Emphasis>) from the south Adriatic,as inferred from the study of the visceral and dermal skeleton

This study examines the interspecific variability and phenetic relationships in six southern Adriatic mullet species: Mugil cephalus (Linnaeus, 1758), Chelon labrosus (Risso, 1826), Liza aurata (Risso, 1810), Liza ramada (Risso, 1826), Liza saliens (Risso, 1810), and Oedalechilus labeo (Cuvier, 1829). Twenty-three morphometric characteristics of the visceral skeleton and the dermatocranium of mullets were analyzed. The major distinguishing characters were those of the jaws. M. cephalus was clearly separated from the other species; O. labeo differed to a somewhat smaller extent; and C. labrosus was the least distinguished species. The species of the genus Liza were phenetically most similar, while the other species of mullet differed significantly from them. The greatest distances were between M. cephalus and C. labrosus, as well as between M. cephalus and O. labeo. This text was submitted by the authors in English.     

Ulva (Chlorophyta,Ulvales) Biodiversity in the North Adriatic Sea (Mediterranean,Italy): Cryptic Species and New Introductions

Ulva Linnaeus (Ulvophyceae, Ulvales) is a genus of green algae widespread in different aquatic environments. Members of this genus show a very simple morphology and a certain degree of phenotypic plasticity, heavily influenced by environmental conditions, making difficult the delineation of species by morphological features alone. Most studies dealing with Ulva biodiversity in Mediterranean waters have been based only on morphological characters and a modern taxonomic revision of this genus in the Mediterranean is not available. We report here the results of an investigation on the diversity of Ulva in the North Adriatic Sea based on molecular analyses. Collections from three areas, two of which subject to intense shipping traffic, were examined, as well as historical collections of Ulva stored in the Herbarium Patavinum of the University of Padova, Italy. Molecular analyses based on partial sequences of the rbcL and tufA genes revealed the presence of six different species, often with overlapping morphologies: U. californica Wille, U. flexuosa Wulfen, U. rigida C. Agardh, U. compressa Linnaeus, U. pertusa Kjellman, and one probable new taxon. U. californica is a new record for the Mediterranean and U. pertusa is a new record for the Adriatic. Partial sequences obtained from historical collections show that most of the old specimens are referable to U. rigida. No specimens referable to the two alien species were found among the old herbarium specimens. The results indicate that the number of introduced seaweed species and their impact on Mediterranean communities have been underestimated, due to the difficulties in species identification of morphologically simple taxa as Ulva.
