Male and female. General habitus dark brown. Head yellow. Frontoclypeus and clypellus black, rest of face yellow. Pronotum dark brown. Mesonotum brown with pale, brown posterior margin. Forewing dark brown with pale spots, venation dark brown with yellow speckles. Hind femur with apices, tibiae and tarsal segments black, setae on hind tibia brown to light brown ( Figs. 2 O View FIGURES 2 , 3 A View FIGURES 3 , 5 O View FIGURES 5 , 6A View FIGURES 6 , 8 View FIGURES 8 N–O). Female seventh sternite broadly rectangular, posterior margin with convex median lobe and more prominent, larger, lateral subtriangular lobes ( Fig.10 H View FIGURES 10 ).

Male genitalia. Pygofer in lateral view triangular, with caudodorsal digitate process, and long, marginally serrated spatulate caudoventral process with basal spine ( Figs. 42 View FIGURES 42 F–G). Subgenital plate broad at base, more or less of uniform width throughout length, apex rounded ( Fig. 42 C View FIGURES 42 ). Style broad at base, apophysis long, slightly constricted midregion, apex conically rounded ( Fig. 42 D View FIGURES 42 ). Connective longer than broad ( Fig. 42 E View FIGURES 42 ). Aedeagus with shaft slightly sinuate in dorsal view, broad in apical 1/3 with almost truncate apex, with basal short curved horn-like process on dorsal margin of shaft, gonopore at midlength of shaft on lateral margin ( Figs. 42 View FIGURES 42 A–B).

Female genitalia. Valvula I slightly curved, sculptured in distal ¼ ( Fig. 12 View FIGURES 12 M–N). Valvula II with toothed area confined to distal¼, teeth widely separated and evenly triangular ( Figs. 12 View FIGURES 12 O–P).

Measurements Male 7.0− 7.3 mm long, 1.8 mm wide across eyes and 2.1 mm wide across posterolateral angles of pronotum. Female 9.6−9.9 mm long, 2.1 mm wide across eyes and 2.6 mm wide across posterolateral angles of pronotum.

Etymology. The species name is descriptive for the serrated saptulate caudoventral process of the male pygofer.

Remarks. S. serratispatulatus   sp. nov. resembles S. ventrospinatus (Nielson)   in general habitus and differs in having the pygofer with a serrate, spatulate caudoventral process and caudally directed basal spine (in S. ventrospinatus   the pygofer process is slender, spine-like and hooked) and aedeagus with a basal, short, curved, horn-like process on the dorsal margin of the shaft ( S. ventrospinatus   without such a process on shaft).
