Arcuatitibia kerzhneri Luo, Lu & Cai, sp. n. (Figs. 1���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). 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); 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); second segment subequal to third antennal segment; third and fourth segments distinctly thinner than second segment (Fig. 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). Collar process distinctly tuberculated (Figs. 1, 2). Anterior pronotal lobe slightly budging with distinct sculptures, middle of anterior pronotal lobe deeply incised, posterior angle not distinct (Fig. 1). Scutellum nearly isosceles-triangleshaped, with distinct Y-shaped carina, apex of scutellum slightly upward (Fig. 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), 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); pygophore without median process; resting structure of phallus as shown in Figs 9-12. Phallosoma ovate in dorsal and ventral views (Figs. 11, 12); basal plate somewhat thick, basal plate bridge much shorter than basal plate (Fig. 10); pedicel long and strong (Fig. 9); struts separate except distal part connected (Fig. 11). Measurements [3 (n= 1)/�� (n= 2), holotype in parentheses]. Length body 26.16 / 27.20���28.16 (28.16). Width abdomen 7.54 / 10.0��� 10.46 (10.46).

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., Published as part of Luo, Zhaohui, Lu, Zhaozhi & Cai, Wanzhi, 2009, Arcuatitibia kerzhneri, a new genus and species of Reduviinae (Hemiptera: Reduviinae) from China, pp. 64-68 in Zootaxa 2121 on pages 65-68, DOI: 10.5281/zenodo.188113

Arcuatitibia Luo, Lu & Cai, gen. n. Type species of genus: Arcuatitibia kerzhneri Luo, Lu & Cai, sp. n. Diagnosis. Size large. Head cylindrical, shorter than pronotum (Figs. 1, 2); eyes large, protruded laterally; ocellus small, somewhat widely separated; anteocular portion of head longer than postocular (Fig. 2), transverse constriction situated behind eyes; rostrum robust, second segment longest; first antennal segment thickest and shortest, distinctly shorter than head; second antennal segment longest. Collar developed; pronotum wider than long, anterior pronotal lobe distinctly shorter and narrower than posterior (Fig. 1); anterior pronotal lobe longitudinally depressed at middle; posterior pronotal lobe much wider than anterior, anterior portion widely depressed along middle, along middle depression with two longitudinal carinae (Fig. 1), lateral angles rounded; scutellum unarmed; fore and mid femora obviously thicker than hind femur, fore and mid tibiae obviously bent and with small sponge furrow each. Female abdomen dilated, male abdomen nearly parallel laterally. Distribution: China. Etymology: The generic name alludes to its arcuate tibiae. Feminine. Remarks: The new genus can be easily distinguished from other related genera of Reduviinae by its fore and mid tibiae being obviously curved., Published as part of Luo, Zhaohui, Lu, Zhaozhi & Cai, Wanzhi, 2009, Arcuatitibia kerzhneri, a new genus and species of Reduviinae (Hemiptera: Reduviinae) from China, pp. 64-68 in Zootaxa 2121 on page 65, DOI: 10.5281/zenodo.188113
