Arcuatitibia kerzhneri Luo, Lu & Cai , sp. n.

( Figs. 1–12 View FIGURE 1 View FIGURES 2 – 12 )

Description. Color. Black. Neck blackish brown, shining; apex of basal antennal, spot nearby ocellus, spots on the wing and connexivum lemon; subapical portion of second antennal segment paler than remaining portion; eyes grayish black; ocellus, third and fourth antennal segments yellowish dark brown.

Structure. Body elongate elliptical ( Fig. 1 View FIGURE 1 ). Antennal segments clothed with sparsely longer erect setae and densely shorter erect pubescence, legs clothed with longer suberect setae. Head small, anteocular portion slightly declined ( Fig. 2 View FIGURES 2 – 12 ); neck smooth and shining; ocellus located on a tubercle; interocellar space subequal to distance between ocellus and ipsilateral eye. Basal 1/3 of first antennal segment thinner ( Fig. 1 View FIGURE 1 ); second segment subequal to third antennal segment; third and fourth segments distinctly thinner than second segment ( Fig. 1 View FIGURE 1 ). First rostral thickest, extending beyond anterior edge of eye, second rostral segment longest, slightly shorter than combined length of the remaining segments, third rostral segment shortest ( Fig. 2 View FIGURES 2 – 12 ). Collar process distinctly tuberculated ( Figs. 1 View FIGURE 1 , 2 View FIGURES 2 – 12 ). Anterior pronotal lobe slightly budging with distinct sculptures, middle of anterior pronotal lobe deeply incised, posterior angle not distinct ( Fig. 1 View FIGURE 1 ). Scutellum nearly isosceles-triangleshaped, with distinct Y-shaped carina, apex of scutellum slightly upward ( Fig. 1 View FIGURE 1 ). Meso- and metasterna, second to third abdominal sterna longitudinally ridged. Hind femur more slender and longer, but shorter than hind tibia; fore and mid tibiae obviously bent ( Fig. 1 View FIGURE 1 ), spongy furrow small, 1/10 as long as tibia; third tarsomere longest; space between fore and mid coxae about twice as long as that between mid coxae; hemelytron of male slightly extending beyond apex of abdomen. Apical part of paramere bent, inner side of apex with a small process, paramere slightly twisted in middle ( Figs. 7, 8 View FIGURES 2 – 12 ); pygophore without median process; resting structure of phallus as shown in Figs 9-12 View FIGURES 2 – 12 . Phallosoma ovate in dorsal and ventral views ( Figs. 11, 12 View FIGURES 2 – 12 ); basal plate somewhat thick, basal plate bridge much shorter than basal plate ( Fig. 10 View FIGURES 2 – 12 ); pedicel long and strong ( Fig. 9 View FIGURES 2 – 12 ); struts separate except distal part connected ( Fig. 11 View FIGURES 2 – 12 ).

Material examined: Holotype, Ƥ; China, Xinjiang, Fukang; 1.VII.2007; Y. L. Su leg ( CAU); paratypes, 13; China, Xinjiang, Fukang; 1.VII.2007; Zhaohui Luo leg ( CAU); 1Ƥ; China, Xinjiang, Fukang; 11.VII.2007; Zhaohui Luo leg ( XIEG).

Etymology: The new species is named in honor of late Dr. I. M. Kerzhner of the Russian Academy of Sciences for his kind help in many ways in our study of Reduviidae and his excellent contribution to the taxonomy of Heteroptera.
