New diagnosis for species of Plutomurus Yosii (Collembola, Tomoceridae), with descriptions of two new species from Georgian caves

Two new species of the genus Plutomurus, P. revazi sp. nov. from Prometheus and Satsurblia caves and P. eristoi sp. nov. from Satevzia Cave are described, illustrated and differentiated from other morphologically closely related species. A high variability in the number of teeth in the claw, unguiculus and mucro of P. revazi sp. nov. demonstrate that these characters are not useful for species diagnosis. However, dorsal chaetotaxy was shown to be stable character for this purpose. Analysis of DNA sequences for the COI and 28S genes is congruent with species-level groups delimited by chaetotaxy, and provide additional support for chaetotaxy as the most reliable morphological character system to distinguish species in Plutomurus. A key to species of the genus Plutomurus found in Georgia is provided, which for the first time includes characters of the macrochaetotaxy.

Studies On the Parasitoid Complex Attacking the Globose Scale Sphaerolecanium prunastri (Fonscolombe) (Hemiptera: Coccoidea) on Prunus Species in Turkey

Abstract The globose scale (GS), Sphaerolecanium prunastri Fonscolombe (Hemiptera: Coccoidea), is a principle pest of Prunus trees, but it is also found on other stone fruit trees in Isparta Province, Turkey. The parasitoid complex was studied in 2006 and 2007 and total of eight (five primary and three secondary) hymenopterous species were found associated with S. prunastri at the five sites studied, but not all species were recorded at all five sites. The most important primary species reducing GS population were Discodes coccophagus, Metaphycus silvestrii, Coccophagus spartanus and C. lycimnia (Hymenoptera: Chalcidoidea). Average percent parasitism at the five sites by primary parasitoid species was 27%. The level of total parasitism of S. prunastri was 71.4% in 2007 in Egirdir. The parasite complex was richer and percent parasitoid-caused mortality was higher at those sites that did not receive chemical treatment to suppress the host population. Seven of the eight species of parasitoids were recovered at Mehmet Tonge in 2006 and at Gonen in 2007.

A new Caryophyllaceae-feeding species of Macrosiphum (Hemiptera: Aphididae) in Republic of Georgia, and a redescription of Macrosiphum hartigi Hille Ris Lambers

Apterous and alate viviparous females and the alate males of Macrosiphum eastopi Barjadze & Blackman sp. n. living on Oberna multifida Ikonn. (=Silene multifida Rohrb.) (Caryophyllaceae) are described from the Republic of Georgia (Caucasus). Type specimens are deposited at the Institute of Zoology, Ilia State University (IZISU), Tbilisi, Georgia; the Natural History Museum (BMNH), London, U.K.; and the University of Catania (UCI), Sicily, Italy. Apterous and alate viviparous females of its close relative M. hartigi Hille Ris Lambers, 1947, living on Silenexa0vulgarisxa0(Moench) Garcke and Stellaria holostea L. (Caryophyllaceae) are redescribed, based on co-types and other material from Austria, France, Italy and Switzerland. The hitherto unknown fundatrix, oviparous females and alate males of M. hartigi are described from Italy and Switzerland. Macrosiphum eastopi sp. n. is differentiated from the morphologically similar M. hartigi and compared with other Macrosiphum species living on Caryophyllaceae. A key is provided to apterous viviparous females of all aphid species recorded on Oberna multifida.

A new species of Aphis Linnaeus (Hemiptera, Aphididae) living on Teucrium polium L. (Lamiaceae).

Aphis polii sp. n. living on Teucrium polium L. (Lamiaceae) is described, based on apterous and alate viviparous females and oviparous females. It has been collected from seventeen localities in mainland France, Corsica, Italy, Ukraine, Lebanon and Iran. The new species is similar to two other Aphis species that feed specifically on plants of the genus Teucrium, but has a relatively longer ultimate rostral segment. Characters are provided to discriminate between the three Teucrium-feeding species, and to distinguish the new species from other morphologically similar Aphis species that feed on Lamiaceae. Type specimens are deposited in the Muséum national dHistoire naturelle, Paris, France (MNHN), the UMR Centre de Biologie pour la Gestion des Populations, Montpellier, France and the Natural History Museum, London, UK (BMNH).

Description of a new species of Hyadaphis Kirkaldy (Hemiptera: Aphididae) from Turkey

Apterous and alate viviparous females of Hyadaphis bupleuriphila sp. n. living on Bupleurum sp. (Apiaceae) and further undetermined Apiaceae are described from the Ankara province in central Turkey. The new species is morphologically similar to Hyadaphis coerulescens (Narzikulov, 1965), H. ferganica Mukhamediev & Akhmedov, 1979 and H. foeniculi (Passerini, 1860). A key to the apterous viviparous females of Hyadaphis spp. in Turkey is given. http://www.zoobank.org/urn:lsid:zoobank.org:pub:2A0A29EA-5FE7-459D-A337-CFA47601874E

Description of oviparous females and alate males of Macrosiphum dzhibladzeae Barjadze, 2010 (Hemiptera: Aphididae) from Georgia

Summary The hitherto unknown oviparous females and alate males of M. dzhibladzeae Barjadze, 2010, living on Euphorbia macroceras Fish. & Mey. and Euphorbia sp. (Euphorbiaceae), are described from resort Bakhmaro (Chokhatauri district, Guria region, Western Georgia). The life cycle of this species is established. Apterous and alate viviparous females and oviparous females of M. dzhibladzeae are compared to the same morphs of morphologically similar M. meixneri Börner, 1950. A key is provided to Euphorbia-feeding Macrosiphum spp. based on males.

Redescription of Neoamphorophora ledi (Wahlgren, 1938) (Hemiptera: Aphididae) from Japan

Summary Apterous viviparous females of Neoamphorophora ledi (Wahlgren, 1938) living on Rhododendron degronianum Carr. (Ericaceae) on Honshu island, Japan, are redescribed and the hitherto unknown alate viviparous females are here described. Rhododendron degronianum is a new host plant species for this aphid. This species is recorded for aphid fauna of Eastern Palearctic for the first time. Keys to species of Neoamphorophora based on apterous and alate viviparous females are given. A key to aphid genera with swollen siphunculi living on species of Rhododendron worldwide based on apterous viviparous females is also provided.
