New species of the aphid tribe Macrosiphini (Homoptera,Aphididae, Aphidinae) from Kazakhstan

Two new species of the genera Uroleucon Mordvilko, 1914 and Pleotrichophorus Börner, 1930 are described from Kazakhstan. Uroleucon dzhungaricum sp. n. feeding on Senecio nemorensis L. (Asteraceae) in the Dzhungar Ala Tau is closely related to U. minor (Börner, 1940). Both these species differ from the closely related U. solidaginis (Fabricius, 1794) in a smaller length ratio between the processus terminalis and the 3rd antennal segment (0.8–1.0 versus 1.0–1.5). The new species differs from U. minor (Born.) in a greater number of the secondary rhinaria on the 3rd antennal segment of the apterous viviparous females (21–37 versus 15–21), in a fewer number of hairs on the cauda (10–16 and 15–23), and in the host plant. Pleotrichophorus ugamicus Kadyrbekov, sp. n. feeding on Artemisia santolinifolia Turcz. is described from the Sairam-Ugam Natural Park (Southern Kazakhstan). The new species is similar to P. glandulosus (Kaltenbach, 1846) and P. achilleae Holman, 1965. Pleotrichophorus ugamicus sp. n. differs from these species in the length ratio of the processus terminalis to the base of the 6th antennal segment (4.1–5.0 versus 5.0–9.0 and 5.1–6.2), in that of the ultimate rostral segment to the 2nd segment of the hind tarsus (0.68–0.76 versus 0.80–0.97 and 0.80–0.90), and in the host plant. This species differs from P. glandulosus in the ratio of the length of dorsal hairs on tergites I–V to the basal diameter of the 3rd antennal segment (1.0–1.2 and 1.4–1.7). In addition, the new species differs from P. achilleae in the length ratio of the 3rd antennal segment to the 6th segment (0.56–0.66 versus 0.70–0.87) and to the processus terminalis (0.67-0.82 versus 1.39–1.80), as well as in the shape of the dorsal hairs. A key to the Palaearctic species of the genus Pleotrichophorus is presented.     

A NEW SPECIES OF THE GENUS IOWANA HOTTES (HOMOPTERA:APHIDIDAE) FROM CHINA*

Abstract This paper deals with a new species of Iowana Hottes, Icrwana zhangi, sp. nov. in China. This new species is closely related to J. frisoni, but differs from the latter in the shape of cauda, length of processus terminalis, length of ultimate rostral segment, and as well as in having smooth siphunculi, having 6‐segmented antennae and primary rhinarium with accessory rhinaria on the ultimate antennal segment. All the type specimens of this new species, collected from Heilongjiang Province, are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing. Iowana Hottes is a new record genus to China.

NEW RECORDS OF TWO GENERA OF TETRACNEMINAE (HYMENOPTERA: ENCYRTIDAE) WITH TWO NEW SPECIES IN CHINA

Abstract  Two new species of Tetracneminae, Encyrtidae, collected from Heilongjiang, Liaoning, and Yunnan, China are described, i.e. Dusmetia latiscapa Xu, sp. nov, and Gyranusoidea yunnanensis Xu, sp. nov. Dusmetia latiscapa Xu, sp. nov differs from Dusmetia cardinalis Hoffer, 1969 in the coloration of the apical forth funicular segment and the fifth-sixth funicular segments of antennae; (2) length of scape; (3) having undeveloped fore wing and (4) the coloration of body. Gyranusoidea yunnanensis Xu, sp. nov. can be distinguished from the Gyranusoidea hecale Noyes et Hayat 1988 by (1) 1 brown match between antennal scrobe and orbit; (2) scape 5.0 times as long as wide, and (3) antennal scape without white ring subapically. Both two genara of Dusmetia Mercet, and Gyranusoidea Compere are recorded for the first time in China. All specimens examined are deposited in Institute of Applied Entomology, Agriculture & Biotechnology College, Zhejiang University, Hangzhou, China.

NOTES ON CARBONARIA SPECIES GROUP OF GENUS FANNIA ROBINEAU-DESVOIDY (DIPTERA: FANNIIDAE), IN CHINA

Abstract  The present paper deals with the Fannia carbonaria species group (Diptera: Fannidae) in China. Eight species are recorded, 2 of them are described as new to science, i.e. F. antilocera sp. nov. and F. tauricornis sp. nov., and F. imperatoria Nishina 2002 is recorded for the first time in China. Fannia antilocera sp. nov. is most closely related to F. minutipalpis (Stein, 1895), but can be identified by the third antennal segment 2.5 times as long as broad, scutum with brownish-grey, hind femur with a row of pv setae only at basal half. F. tauricornis sp. nov. is very close to F. capricornis Xue, 1996, but is separated on the third antennal segment 3 times as long as wide, basicosta yellow, legs dark brown, the first sternite with hairs, surstylus without expansion on median dorsal; bacilliform process with 2 short processes. In addition, F. tauricornis sp. nov. is fairly related to F. trigonfera Chillcott, 1961, F. japonica japonica Nishida, 1974, F. japonica amamiensis Nishida, 1975, but sets apart by several distinctive characters: cereal plate with longer arm of outside projection, surstylus without expansion on median dorsal, and bacilliform process with 2 short processes. The paper also reports the characters of the F. carbonaria species group. The group as a whole can be recognized by the hind femur without rows of pv setae at apex, the mid tibia with 2 ad and 2 pd setae and the single strong prealar seta.
