The finding of three immature nymphs of Prosopistoma Latreille, 1833 (Ephemeroptera, Prosopistomatidae) in an upstream site of Baishih River represents the first record of this rarely collected genus in Taiwan. These nymphs were discovered through extensive monthly sampling at the riffle habitats from 13 undisturbed sites over two years (Dec 2008-Nov 2010). The coloration pattern of the collect...

Many spatial patterns observed in nature emerge from local processes and their interactions with the local environment. The clustering of objects by social insects represents such a pattern formation process that can be observed at both the individual and the collective level. In this paper, we study the interaction between air currents and clustering behaviour in order to address the coordinat...

Types of three filistatid species described by Roewer (1960, 1962) from Afghanistan are redescribed and two of them transferred to other filistatid genera. The new combinations proposed are: Zaitunia afghana (Roewer 1962) comb. n. (ex. Filistata Latreille, 1810) and Tricalamus lindbergi (Roewer, 1962) comb. n. (ex. Pritha Lehtinen, 1967). The taxonomic position of Pholcoides afghana Roewer, 196...

The present work studied the diversity of Formicidae in two agrosystems Bejaia, a lemon orchard located at INRAA and an orange Amizour. We used transect method by combining three (3) sampling methods: Barber Pots or Pitfall, Bait, manual capture. identified 18 ant species representing 11 genera subfamilies: Dolichoderinae (Tapinoma magnum), Formicinae (Cataglyphis, Camponotus, Lasius, Plagiolep...

community-acquired pneumonia and brucellosis are of the main agents causing mortality in the world. the most important limitations for the identification of these agents include their high resistance against environmental conditions, impossibility of rapid and on time diagnosis, low level of infective dose, and lack of existence of vaccine against many types of them. hence, on time action and d...

Abstract:  This work was carried out to identify decapods of the Bushehr interidal zone, northern coast of the Persian Gulf. Specimens were collected from eight stations along the coast. During this survey, twelve species were identified, including one alpheid shrimp (Alpheus lobidens), three Anomura (Petrolisthes rufescens, Porcellana persica, Clibanarius signatus) and eight Brachyura (Portunu...

The genus Lesteva Latreille, 1797 has been recently, intensively studied in China and twenty species are currently known from this vast territory (Rougemont, 2000; Watanabe, 2005; Li & al., 2005; Ma & al., 2012; Ma & Li, 2012). In this paper, I describe a new species of the genus with yellow round elytral spots, as well as provide records of L. (s.str.) pulcherrima Rougemont, 2000 and L. (s.str...
