Anopheline Mosquitoes

To study the prevalence of anopheline mosquitoes, over 180 sites were sampled in malaria-endemic areas of Asir region, Saudi Arabia, during June 1999-April 2001. A total of 7085 larval and 754 adult female Anopheles spp. specimens were collected. Seven species were identified: An. dthali, An. rupicolus, An. sergentii, An. arabiensis, An. multicolor, An. turkhudi and An. pretoriensis. Both An. arabiensis and An. sergentii are known vectors of malaria in the region. An. dthali occurred in all sites and was the most abundant species. An. turkhudi was collected in low numbers as larvae only. An. multicolor and An. pretoriensis were recorded for the first time in Asir region. An. sergentii is a species of the northern areas of the region, whereas An. arabiensis was more prevalent in the south

Feeding and vertical distribution of pelagic chaetognaths were studied at coastal and open-sea stations in the northern part of the South Adriatic Pit during five cruises from April 1993 to February 1995. Chaetognaths were more numerous in the upper 100 m, decreased conspicuously with depth, and were captured only rarely between 600 and 1000 m. Copepods were the main food for the most abundant species in all layers. Cannibalism was evident in all species. Feeding on fertilized chaetognath eggs by Pseudosagitta lyra and Mesosagitta decipiens is reported for the first time. The food containing ratio (FCR) and number of prey items per chaetognath (NPC) of Flaccisagitta enflata were highest during the reproductive period. Higher FCRs and NPCs for M. decipiens and P. lyra were noted below 100 m, where the contribution of older specimens increased with depth and the abundance of copepods decreased.

A New Species

The spider mite genus Neotetranychus Trägårdh is reported for the first time from Saudi Arabia (SA) based on N. longisetus n. sp., collected from Heliotropium arbainense (Boraginaceae). The new species is described and illustrated from the adult female, and three species, Mixonychus (Bakerina) aculus (Chaudhri), Paraplonobia (Anaplonobia) harteni (Meyer) and Sonotetranychus daleae (Tuttle and Baker) (Acari: Tetranychidae) are reported as new to the mite fauna of SA. Mixonychus (B.) aculus (Chaudhri) is re-described and illustrated based on adult female, collected from an exotic mesquite species from Mexico and Caribbean, Prosopis juliflora (Sw.) DC. (Fabaceae). Moreover, the species, Evertella orissaensis (Prasad) n. comb., is moved from the genus Mixonychus Ryke and Meyer to the genus Evertella Meyer and Mixonychus (Bakerina) ganjuis (Qian, Yuan and Ma) n. comb., is moved to the subgenus Bakerina Chaudhri from the subgenus Mixonychus. A key to the world species of the genus Mixonychus is also provided. Additionally, legs chaetotaxy of all known species of the genus Mixonychus is given.

The family Stephanidae (Hymenoptera: Stephanoidea) is recorded for the first time from Saudi Arabia. It is represented by two species belonging to the genus Foenatopus, F. bisignatus Aguiar & Jennings, 2010 and F. cf. turcomanorum (Semenov, 1891). A new species, Profoenatopus bimaculatus sp. nov. from Asir region is also described and illustrated.

Citrus groves in Florida were sampled during February and March 1991 to determine the occurrence, frequency and distribution of thrips including Thrips palmi Karny in open flowers of citrus. Frankliniella bispinosa (Morgan) was the dominant species accounting for 65% of identified specimens from St. Lucie, Palm Beach, Hendry, Lee and DeSoto counties. Frankliniella kelliae Sakimura was the second most abundant species comprising 34% of 2,067 slide-mounted specimens subsampled from collections. Frankliniella kelliae was found for the first time in St. Lucie and Indian River counties and this species was the most abundant thrips collected from citrus flowers in Indian River and Dade counties. Five species of thrips including Frankliniella occidentalis (Pergande), T. orientalis (Bagnall), T. palmi and Adraneothrips pallidus (Watson) were collected for the first time in February and March 1991 on citrus flowers along with F. insularis (Franklin) reported previously. A single adult female, T. palmi, was collected from a ‘Tahiti’ lime flower sample in Dade County. The predaceous thrips, Aleurodothrips fasciapennis (Franklin), was collected for the first time from flowers in a mixed block of citrus varieties in Dade County. A key to the species of adult female terebrantian thrips found on citrus flowers and floral buds in Florida is provided.

The present study is one in a series of planned studies aiming to catalogue the whole order Diptera in both Egypt and Saudi Arabia. All known Egyptian and Saudi Arabian conopid taxa are systematically catalogued in the present study. Three species are recorded herein for the first time from Saudi Arabia: Conops (Asiconops) elegans Meigen, 1804 and Thecophora atra (Fabricius, 1775) (Al-Baha region, south-western of Saudi Arabia), and Conops (Conops) quadrifasciatus De Geer, 1776 (Tabuk region, north-western of Saudi Arabia). Physocephala variegata (Meigen, 1924) is also recorded for the first time from Gebel Elba, the south-eastern triangle of Egypt. Considering that Gebel Elba in Egypt and Al-Baha in Saudi Arabia are affiliated to the Afrotropical Region, this is the first time Physocephala variegata and Thecophora atra have been recorded from the Afrotropical Region. An updated taxonomy, world and local distributions, dates of collection and some coloured photographs are provided.

With the purpose of establishing the taxonomic composition of the heteropod assembly that inhabits the Colombian Pacific,zooplankton samples were collected in March 2014 along a coastal- offshore transect and later analyzed. Twelve speciesbelonging to three families and three genera were identified. Atlanta lesuerii was the most abundant species in the study area. In addition, A. frontieri, A. oligogyra, A. inflata and A. plana were recorded for the first time in the South American Pacific, as well as A. helicinoidea in the Colombian Pacific. This work contributes in a significant way in the knowledge of the heteropod molluscs of the Colombian Pacific.

Information on the Sphagnum mosses of the South Ossetia is generalized, the resulted list is presented. Nine species of Sphagnum are included in the list, whereabouts data and references to the publications are given, and the presence of a sample in the Herbarium of the Komarov Botanical Institute RAS (LE) is noted. The species Sphagnum platyphyllum (Lindb. ex Braithw.) Warnst. rarely occurring in the Caucasus is reported in the South Ossetia for the first time. The species was found in the Caucasus, South Ossetia, at the side of the Ertso Lake (42°28ʹN, 43°45ʹE), 1720 m a. s. l., among sedge thickets at the margin of the overgrowing lake. The peculiarities of its occurrence and ecological conditions are considered. Its distribution in the Caucasus and in the world is discussed.
