NORTH-WESTERN JOURNAL OF ZOOLOGY 12 (2) ©NwjZ, Oradea, Romania, 2016 CORRESPONDENCE –Notes http://biozoojournals.ro/nwjz/index.html  First record of the rare Mymarid genus Eustochus Haliday (Hymenoptera: Mymaridae) from Romania, with notes on biology Eustochus Haliday, a genus with a northern hemi-sphere distribution (Huber 1997, Xu & Lin 2003, Huber & Baquero 2007), is represented by a total of 9 valid species (Huber & Baquero 2007, Noyes 2014). Eustochus Haliday belongs to the Mymari-dae, among the smallest known Hymenoptera. Three species are described and recorded from Europe: Eustochus atripennis (Curtis, 1832), Eusto-chus besucheti Bakkendorf, 1965, and Eustochus con-fusus Huber & Baquero, 2007. Debauche (1948) published the first illustrated identification key to the Mymaridae genera from Europe that included Eustochus Haliday. Huber & Baquero (2007) pub-lished the first key to world species. Morphologi-cal terms follow Huber (1997), Triapitsyn & Huber (2000), Xu & Lin (2003), Donev (2006), Huber & Baquero (2007), Triapitsyn et al. (2013), Amini et al. (2014), Haghayeghi Nosrati et al. (2014), Bayegan et al. (2014), Lotfalizadeh (2014), Lotfali-zadeh & Hosseini (2014), Maral et al. (2014), Pri-cop & Moglan (2014), Noyes (2015) and Çetin Er-doğan, 2015. Linguistic considerations on some aspects of terminology used in the study of certain Hymenoptera are given by Pricop & Pricop (2015).

Eustochus atripennis is the most widespread species of the genus and is newly recorded from Romania. Eustochus confusus was previously de-scribed from Northern Spain and now is newly re-corded from Romania. Pricop (2013) also illus-trated and keyed Eustochus Haliday. Regarding past contributions to the Mymaridae recorded from Romania, some important data was given by Boţoc (1965). Most recent contributions to the Mymaridae genera recorded from Romania have been published by Pricop (2009, 2013, 2014a, 2014b) and Pricop & Andriescu (2011). All specimens were collected from two different locations from Central and Eastern Romania (Figs. 1a, b), from Șeica Mare, Sibiu county (Fig. 1a) and Ceahlău Mountain, Neamţ county (Figs. 1a, b). The specimens of Eustochus were collected using the entomological sweep net, the in-terceptor trap and by rearing parasitized eggs from the Carpathian Mountains (Romania). All specimens are de-posited in the insect collection of the Department of Biol-ogy, “Alexandru Ioan Cuza” University of Iaşi, Romania. All specimens were slide mounted in Canada balm. Pho-

tographs were taken using a Canon digital camera at-tached to an IOR optical microscope. The map was made using ArcView GIS 3.1 software. Some relative measure-ments are given. For scanning electron microscopy we used Vega Tescan electron microscope.

Genus Eustochus Haliday, 1833; Type species: Eustochus atripennis (Curtis, 1832) Diagnosis. Eustochus Haliday is easily identified based on the following characters: 4-segmented tarsi; metasoma petiolated; head, mesosoma, dor-sum of petiole and coxae strongly sculptured (Huber 1997, Huber & Baquero 2007). Mandibles are tri-dentate (Huber & Baquero 2007). Female funicle 6-segmented, clava 2- or 3-segmented; forewing with long venation, marginal vein is lin-ear (Huber 1997, Huber & Baquero 2007, Xu & Lin 2003). In females, mps. only on F4 to F6. Male ap-terous, flagellum 9-segmented (Viggiani 1970). Eustochus is related to Caraphructus Walker, which share several characters as the strongly reticulated body and relatively long forewing marginal vein (Xu & Lin 2003). Females of Eustochus differ from those of Caraphructus because of the 2- or 3-segmented clava (Xu & Lin 2003, Huber & Baquero 2007).

Hosts. Coleoptera. Distribution. Eustochus species have been re-

corded from the northern hemisphere: (mainly from the Holarctic Region): Canada, SUA, few countries from Europe, Russia, China, South Ko-rea and Japan (Huber & Baquero 2007, Noyes 2014). Eustochus Haliday is new to Romania.

Notes. Eighteen Mymaridae genera are re-corded from Romania, from a total of twenty-one genera recorded from Europe (Table 1). Pricop (2009) provided a review of all the Mymaridae, previously recorded from Romania. Genera Dico-pus, Pseudocleruchus and Omyomymar ware later recorded from Romania (Pricop 2011, 2013, 2014a and Pricop & Andriescu 2011). Pricop (2013) pro-vided also an identification key to the Mymaridae genera recorded from Europe. Genera Caraphrac-tus, Macrocamptoptera and Ptilomymar are not yet recorded from Romania (Table 1).

Key to Eustochus species recorded from Romania: (2) Ovipositor very long, distinctly exserted be-

yond apex of metasoma (Fig. 2h); clava about as long as the combined length of F1 and F2 (Fig. 2d); FWL/FWL ratio is about 3, forewing base with two or three lines of hairs (Figs. 2e, f) E. atripennis

(1) Ovipositor short, tip of ovipositor is not ex-serted beyond apex of metasoma (Figs. 3e, f); clava longer than the combined length of F1 to F2 (Fig. 3b); FWL/FWW ratio more than 4, fore-wing base with a single line of hairs (Figs. 3c, d) E. confusus

Eustochus atripennis (Curtis, 1832) [= Mymar atripennis Curtis, 1832] Material examined. 3♀, 16.08.1980, Șeica Mare (Fig. 1a), Sibiu County, collected with the interceptor trap from the forest vegetation, 400m elev. (Leg. I. Andriescu).

Diagnosis. Body length from about 0.9 to 1.2 mm in slide mounted specimens. General body colour is brown. Morphology of Eustochus atripen-nis as in Figs. 2a, b, c, d, e, f, g, h. Mesosoma strongly convex; length/height of mesosoma about 1.2 – 1.3X (Fig. 2g). Antenna (Figs. 2c, d): scape shorter than the combined length of F1 to F2; clava about as long as the combined length of F1 to F2. Clava usually longer than the combined length of F4 to F6 or at most equal to F4 to F6 length combined. Mps. only on F4(1), F5(2) and F6 (2). Pedicel shorter, or at most about as long as F1; F4 much longer and slander than F5 (Fig. 2d). Forewings: FFWL/FWL ratio = 3.1 (Fig. 2f); fore-wing venation is long (Fig. 2e); base of forewing with 2-3 rows of hairs (Fig. 2d). Length of fore-wing fringe is half as forewing broadest part (Fig. 2f). In females of E. atripennis, the ovipositor is very long, distinctly exserted beyond apex of me-tasoma (Fig. 2h); the exserted part of ovipositor about as long, or usually longer than hind tibia length. In our specimens the ovipositor length is about 2.5 times length of hind tibia. Eustochus atripennis is distinguished from E. besucheti, the only other European species with a long oviposi-tor, by its bigger size, longer funicle segments and longer forewing venation (Bakkendorf 1965, Huber & Baquero 2007).

Taxonomic notes. E. atripennis is easy to iden-tify, two characters clearly define this species: F1 to F3 are relatively long (Fig. 2d) and the oviposi-tor that is long and exerted past tip of metasoma

(Fig. 2h). In our specimens the ovipositor is slightly longer and the forewings are a little nar-rower than in the re-description from Huber & Baquero (2007). In E. atripennis the petiole is long and narrow, from lateral view the length/wide ra-tio = 3,6 – 4 (Figs. 2a, g). The petiole of E. atripennis is longer than the petiole of E. confusus.

Hosts. Unknown. Distribution. E. atripennis was recorded from:

England, Belgium, Czech Republic, Denmark, France, Germany, Hungary, Japan, South Korea, Slovenia, Spain, Switzerland, United Kingdom (Huber & Baquero 2007, Noyes 2014) and now is newly recorded from Romania. Eustochus confusus Huber & Baquero, 2007

Material examined. 2♀, 7.08.2010, Ceahlău

Mountain (Figs 1a, b), near the upper monastery, 1750m elev., Neamţ County, collected with the sweep net from sub-alpine grassland vegetation, dominated by grasses (Festuca spp., Deschampsia sp.), near a small stream (Leg.

length of F4 to F6. Mps. only on F4(1), F5(2) and F6(2). Pedicel is longer compared with the length of F1; F4 about as long as F5 or shorter, F6 the shortest funicle segment. Forewing venation is relatively short (Figs. 3c, d); base of forewing with only one row of hairs (Fig. 3c). Length of forewing fringe is about as long as forewing broadest part (Fig. 3d). Ovipositor is short, tip of ovipositor is not exserted beyond apex of metasoma and less than 0.8 times length of hind tibia (Figs. 3e, f).

Taxonomic notes. E. confusus is distinguished from the European species because of the non-exserted ovipositor, the ovipositor is clearly shorter than the hind tibia (Figs. 3e, f) and the nar-rower forewings (in our specimens FWL/FWW ratio = 4.8). E. atripennis and E. besucheti have long, exserted ovipositors that are longer than hind tibia. The petiole of E. confusus is compact and

relatively short (Figs. 3a, e), petiole length/wide ratio = 3.3 – 3.4 (from lateral view).

Hosts. Coleoptera eggs (this is the first host re-cord for E. confusus).

Distribution. E. confusus was described from Northern Spain (Huber & Baquero 2007) and now is newly recorded from Romania. Regarding this species, our collection site (Ceahlău Mountain) represents the most north-eastern point of distri-bution. Genus Eustochus Haliday, 1833 is here reported for the first time from Romania. Eustochus Haliday is rarely collected and belongs to the mountain eco-systems. Eustochus atripennis (Curtis) was collected from the forest habitat of Șeica Mare – Sibiu County. Eustochus confusus Huber & Baquero was currently collected from the upper protected sub-

Aphids Living on Berberis in Iran: New record of Liosomaphis atra Hille Ris Lambers, 1966 (Hem.: Aphididae) Berberis (Berberidaceae) is a large genus of decidu-ous and evergreen shrubs growing throughout the temperate and subtropical regions of the world. The European barberry, Berberis vulgaris, is the most well-known species which is common in Europe, North Africa, the Middle East, and central Asia. Berberis spp. grow in the wild and produce crops rich in vitamin C. Nowadays, Iran is the country in which edible berries are used the most frequently. Berberis spp. like other plants are in-fested by a number of aphids. There are more than 18 aphid species living on Berberis spp. in the world including Amegosiphon platicaudum (Narzi-kulov, 1953), Aphis aurantii Boyer de Fonscolombe, 1841, Aphis berberidorum Ortego & Mier Durante, 1997, Aphis citricidus (Kirkaldy, 1907), Aphis nastur-tii Kaltenbach, 1843, Aphis odinae (van der Goot, 1917), Aphis patagonica Blanchard, 1944, Aphis pomi De Geer, 1773, Aphis spiraecola Patch, 1914, Aula-corthum solani (Kaltenbach, 1843), Berberidaphis lydiae (Narzikulov, 1957), Liosomaphis atra Hille Ris

Lambers, 1966, Liosomaphis berberidis (Kaltenbach, 1843), Liosomaphis himalayensis A.N. Basu, 1964, Liosomaphis ornate Miyazaki, 1971, Macrosiphum euphorbiae (Thomas, 1878), Myzus persicae (Sulzer, 1776), and Rhopalosiphum rufiabdominale Sasaki, 1899 (Hodjat 1993, Blackman & Eastop 2006, Holman 2009, Blackman & Eastop 2015). So far, only three aphid species were reported from Ber-beris in Iran including Amegosiphon platicaudum, Aphis pomi and Liosomaphis berberidis (Hodjat 1993, Rezwani 2004). In the course of studies of aphid fauna of Iran since 2006, Liosomaphis atra was col-lected on Berberis integerrima, which is here a new record for aphid fauna of Iran. In this paper the morphological and biological characteristics of aphid species living on Berberis in Iran are pre-sented and an identification key is provided. Amegosiphon platicaudum (Narzikulov, 1953) (Aphidinae: Macrosiphini) This species was also described as Elbourzaphis be-hboudii by Remaudière and Davatchi in 1959. Indi-viduals of this species have rather elongate body and long appendages, 1.63–2.7 mm long. Body color, in alive specimens, pale green to yellowish with an irregular red spinal stripe. Antennal tu-bercles well-developed, broadly divergent. Si-phunculi slightly and uniformly swollen over most of length which narrowing at base and apex, with spinulose imbrications. Cauda tongue-shaped with 11–27 rather short hairs. Based on the specimens collected in this study, apterous vivipa-rous females and oviparous females with 1–4 and 1–6 secondary rhinaria on the third antennal seg-ment, respectively. Alate males with 0–1 secon-dary rhinaria on the base of antennal segment VI. In oviparae, antennal segment IV 0.55–0.68 times shorter than antennal segment III; Hind tibia 0.74–0.89 times shorter than body length; cauda with 16–24 hairs. Alatae males with 13–15 hairs on their cauda; antennal segment IV is 0.67–0.74 times shorter than antennal segment III; and hind tibia 0.78–0.88 times shorter than body length.

Some considerable morphological differences were found between the specimens that have been described by Remaudière and Davatchi (1959) and the specimens collected from Kerman province in this study (Table 1). In apterous viviparous fe-males the ratio between ultimate rostral segment and second segment of hind tarsus, and the num-ber of hairs on cauda were different between the two specimens (Table 1). In apterous oviparous females the ratio between length of processus ter-
