NEW SPECIES OF GENUS ANTHOCORIS FROM CHINA (HEMIPTERA: ANTHOCORIDAE)

原花蝽属(Anthocoris Fallen)在花蝽科中种类较多而且常见,我国已记载19种。本文记述2个新种。文中所用长度单位为mm。 秦岭原花蝽Anthocoris qinlingensis新种(图1—4) 头黑,长0.50,宽0.52,眼前部分长:眼前缘以后部分长=1:1。触角第1节、第2节端部1/4以及第4节黑褐,第2节基部3/4黄褐,第3节基半黄褐或全部黑褐,各节毛长不超过该节直径,各节长0.22:0.64:0.42:0.42。前胸背板黑色,长0.58,领宽0.48,后缘宽1.18,毛被短,平伏;侧缘几不伸出,前角处平缓,胝后缘凹陷较浅,胝后横皱明显,延至背板后缘。前翅革质部全具光泽,毛被短,平伏;爪片淡黄白,基部、内缘及端部褐色。

Two new species of Genus Anthocoris are described in this paper. The type specimens are deposited in Nankai University. All the measurements are in millimetres. Anthocoris qinlingensis Bu et Zheng sp. nov. (Figs. 1,2,3,4)Brown; 2nd antennal seg. except apex, base of 3rd antennal seg. and tibia ochraceous, or base of 3rd antennal seg. and base of tibia piceous; hemelytra shining, color pattern as in fig. 4; femur brownish to piceous. Paramere broa:l, inner lateral margin swelled in two places, the subapical swelling stronger (figs. 2,3,). Pubescence short and decumbent. Body length 3.6-4.2, width 1.2-1.4; antennal seg. lengths 0.22:0.64:0.42:0.42; length exocorium 1.28, cuneus 0.78.Closely allied to A. montantts Zheng in bo ly form, structure of pronotum, and color pattern of hemelytra. Differences are: new species body broader, coloration lighter, the median dark fascia on hemelytra non-continuous (fig. 4). but in montanus is a continuous transverse band (fig. 5); paramere differently shaped.Holotype (?): Shaanxi (Qinling 33°50'N, 107°40'E), 1916. Ⅷ. 22.; allotype (?), paratypes 5 (?) 3 (?): as above.Anthocoris fasciatus Bu et Zheng sp. nov. (Fig. 6)Body slender. Black; 2nd antennal seg. except apex ochraceous; hemelytra shining, base and apex black, median transverse band black; color pattern as in Fig. 6; femur and hind tibia piceous, fore tibia ochraceous, middle tibia ochraceous to piceous. Pubescence long and erect or semi-erect. Body length 3.07, width 0.93; antennal seg. lengths 0.14:0.50:0.26:0.32; length exocorium 1.04, cuneus 0.54.Allied to A. miyamotoi Hiura (from China and Japan) and A. disianli Kiritschenko (from Burma) in having slender body form, strong lustre and distinct color spots; but differs clearly from them in the proportion of antennal segment lengths and color pattern of forewing.Holotype (?) Yunnan (Wilding 26°N, 102°40E), 1986. Ⅷ. 10.
