中国的厚盲蝽属和拟厚盲蝽属(半翅目:盲蝽科)

ON CHINESE SPECIES OF EURYSTYLUS STAL AND EURYSTYLOPSIS POPPIUS (HEMIPTERA: MIRIDAE)

本文共记述盲蝽科盲蝽亚科的厚盲蝽属(Eurystylus stal)和拟厚盲蝽属(Eurystylopsis Poppius)的中国种类共7种,其中包括1个新种:中国拟厚盲蝽Eurystylopsis chinensis sp.n.(模式产地:四川、云南),1个中国新记录种:缅甸厚盲蝽Eurystylus burmanicus(Distant)。提出1项新组合关系:即原已由Kititschenko(1913)移人Eurystylus属的Calocoris clavicornis Jakovlev应归于Eurystylopsis属中。并肯定淡缘厚盲蝽Eurystylus costalis Stal可严重破坏枣花,影响枣树结实,造成明显的减产。

Five species of Eurystylus found from China (Eu. costalis Stal, sauteri Poppius, ,luteus Hsiao, coelestialium (Kirkaldy), burmanicu; (Distant)) are keyed and annotated in this paper, in which burmanicus is recorded for the first time from China. Details of aedeagus are described and figured except those of sauteri.The following characters are considered diagnostic for the genus Euryszylopsis in addition to the Poppius’ original description in 1911: (?). Some species could be dimorphic sexually. 2. Body more elongate and less stout than in Eurystylus. 3. Head lacks a black velvety spot in front of eye 4. First antennal segment without pale-colored sericeous pubescence. 5. Vesica without sc-lerotized spine-like or plate-like appendages. 6. Body with characterized color-patterns.Two species of Eurystylopsis are included in this paper: Eu. clavicornis (Jakovlev) is transferred here from Eurystylus as a new combination, and Eu. chinensis is a species new to science:Eurystylopsis chinensis sp. nov.Close to Eurystylopsis harmandi Poppius, but with the following differences: Head almost uniformly light brown with only a black spot on lora. Vertex wider ( = 1/2.7 of head width). Apical 2/3 of front and middle tibiae, basis and apical 1/5-1/4 of hind tibia yellowish brown.Head width 1.27mm, vertex width 0.47mm, eye width 0.35mm. Pronotum length 1.25mm, width 2.35 mm. Corium length 3.57 mm. Head apex to corium apex 5.27 mm. Antennal segments length 1.18:3.1:0.99:? mm.Holotype ♀, Sichuan (Mt. Ernei); 1938. Ⅷ.8 (kept in Nankai University, Tianjin). Paratype 1♀, Yunnan (Pin-bian, 1350m), 1956. Ⅵ.18 (kept in the Institute of Zoology, Aca-demia Sinica, Beijing).
