Biodiversity of Asterina species on Neotropical host plants: new species and records from Panama

Two new species of the genus Asterina are described from living leaves collected in provinces Chiriquí and Bocas del Toro in western Panama. Asterina alloplecti on Alloplectus ichtyoderma (Gesneriaceae) differs from other Asterina on Gesneriaceae by its stalked appressoria and host relationship. Asterina compsoneurae on Compsoneura sprucei (Myristicaceae) can be distinguished from other members of Asterina on Myristicaceae by its larger ascomata, larger, prominently spinose ascospores and host relationship. New records for Panama are Asterina corallopoda from a new host plant species (Solanum trizygum, Solanaceae), A. diplopoda, A. ekmanii from a new host plant species (Gonzalagunia rudis, Rubiaceae), A. siphocampyli from a new host plant genus and species (Burmeistera vulgaris, Campanulaceae) and A. styracina from a new host-plant species (Styrax argenteus, Styracaceae). This study increases the number of species of Asterina known for Panama from 12 to 19 and the number of Asterinaceae from 14 to 21. Asterina corallopoda, A. diplopoda, A. ekmanii, A. siphocampyli and A. styracina are illustrated for the first time. A phylogeny inferred from the analysis of LSU rDNA sequences of species of Asterina is presented. The diversity and host-plant patterns of known Neotropical species of Asterina are discussed.     

REVISION OF THE GENUS APHYTIS (HYMENOPTERA: APHELINIDAE) WITH DESCRIPTIONS OF TWO NEW SPECIES FROM EGYPT

Abstract  The Egyptian species of the aphelinid genus Aphytis Howard are reviewed. Aphytis azai Abd-Rabou and Aphytis matruhi Abd-Rabou are described as new species from Egypt. Each species is briefly diagnosed and known information on hosts and distributed is given. A. azai sp. nov. is similar to A. melinus but different in the measurement of antennal segments. A. matruhi sp. nov. differs from A. lepidosaphes by the relative length of propodeum, metanotum and scutellum. A key to the Egyptian species of Aphytis is provided.

葱属根茎组8种21居群植物的核型研究

对葱属根茎组Allium sect.Rhiziridium的8种21个地方居群的核型进行研究,以期为解决该组的种间亲缘关系和物种进化机制提供依据。贺兰韭A.eduardii和阿拉善韭A．flavovirens2个种的核型以及辉韭A．strictum的六倍体核型均属首次报道。研究结果表明：贺兰韭A.eduardii、阿拉善韭A.tlavovirens、北韭A.lineare、蒙古韭A.mongolicum和滩地韭A．oreoprasum的各居群均为二倍体,核型类型为Stebbins的2A型;韭A．tuberosum和野韭A.ramosum的各个居群均为四倍体,核型类型为2A型：辉韭A．Jtrictum的4个居群均为六倍体,核型类型为2B型。通过研究可以得出如下推论：（1）该组植物中存在着大量的多倍体或多倍体系列,染色体数目变化与物种进化具有密切相关性,多倍化可能是根茎组植物核型进化的重要机制之一;（2）随体染色体多为st或t染色体,均位于短臂末端;（3）可以认为辉韭是以增加倍性来克服该物种扩大新的生存空间所带来的困难;（4）现今栽培的韭可能是由野生的二倍体韭和四倍体韭经过长期人工驯化而来的,现今栽培的三倍体韭可能是二倍体韭和四倍体韭杂交而来,并且以无性繁殖方式保存三倍体类群的存在。

A revision of the genus Annesorhiza (Apiaceae)

The genus Annesorhiza is revised and twelve species are recognized, of which two are newly described: A. altiscapa, A. burttii, A. flbrosa, A. flagellifolia, A. grandiflora, A. lateriflora, A. latifolia, A. macrocarpa, A. nuda, A. schlechteri, A. thunbergii and A. wilmsii. A. marlothii is reduced to synonymy under A. lateriflora , a species hitherto poorly known as Peucedanum lateriflorum. A. thunbergii is only known from the type specimen. A. elata, A. hirsuta and A. villosa are sunk under A. grandiflora. A. fúicaulis has recently been excluded from Annesorhiza on the basis of fruit structure. A key to the species is provided, an update on the nomenclature, typification of names and distribution maps are provided for all the species.     

Taxonomy and preliminary phylogeny of the parasitic genus Apocephalus, subgenus Mesophora (Diptera: Phoridae)

Abstract. The species of Apocephalus , subgenus Mesophora , are revised and twenty-eight species are recognized, including the following twenty-two new to science: from the Nearctic Region A. brunnipes, A. gemursus, A. pristinus, A. setialvus and A. unitarsus , and from the Neotropical Region A. absentis, A. adustus, A. anfractus, A. angustistylus, A. bisetus, A. brevicercus, A. curtus, A. gracilis, A. hansoni, A. leptotarsus, A. longistylus, A. micrepelis, A. moraviensis, A. prolatus, A. trisetus, A. tritarsus and A. truncaticercus. Additionally, three species known only from female specimens are described but not formally named. A lectotype is designated for A. mortifer Borgmeier, and immature stages of A. borealis, A. antennatus and A. mortifer are described. Unlike larvae of other Apocephalus species, all of which are parasites of ants (Hymenoptera: Formicidae), those of Mesophora species are parasites of various other hosts.     

Redescription of Pennella sagitta (Copepoda: Pennellidae) from Histrio histrio (Pisces) in the North-west Atlantic Ocean with a provisional review of the genus Pennella

Pennella sagitta (L.) is redescribed from fresh specimens recovered from Histrio histrio (L.) and from material in the collection of the Smithsonian Institution. A small, delicate parasitic copepod, P. sagitta is shown to be a valid species, found only on fishes of the family Antennariidae. Attempts of earlier workers to synonymize P. diodontis with P. sagitta are rejected, and the distinguishing features of both species are presented. A neotype is proposed from material described herein, due to a lack of the original holotype. A provisional review of the genus Pennella Oken, 1816 is provided, and the taxonomic status of 31 species is discussed. Pennella exocoetus is described from material in museum collections. Seven species, P. balaenoptera, P. diodontis, P. exocoetus, P.filosa, P. instructa, P. makaira and P. sagitta are considered as valid members of the genus. The remaining species are reduced to synonymy with valid species or accorded the status of species inquirendae.
