Diagnosis.

Saussurembia borba sp. nov. can be distinguished from the other species of the genus by having a strong depression on external edges of Md, basal cerci longer than apical cerci, 10Lp1 inconspicuous.

Description.

Male (holotype). Uniformly yellowish brown with some color details: abdomen (except nine and ten segment) and cerci whitish. Total length 7.25. Head oval and elongate (Fig. 7 ) width/length = 0.87; anterior margin of the clypeus slightly convex, postocular suture present; eyes large OR = 0.51; Md with external edges with a strong concavity, 1-1 incisor teeth and 0-0 molar teeth (almost inconspicuous, Fig. 7 ); Mm broad, clearly defined, Sm with anterior margin membranous (Fig. 8 ). Forewing length 4.60, hindwing length 4.15. Wing base union type B, wing venation: Sc, R1, Rs, Cu, and A conspicuous; Cu not forked, Ma and Mp diffuse, less conspicuous, clearly not reaching wing edge (Fig. 9 ); cross-veins in forewing: R1-Rs: 4, Rs-Ma: 1-2, Ma-Mp: 2. Basitarsus of hind leg narrow (Fig. 10 ): length 0.37, width/length = 0.19; one row of setae on retrolateral face, one row on anterolateral face (Fig. 10 ). Terminalia (Figs 11 , 12 ), 10T partially and longitudinal divided into two subequal plates, 10Lp1 inconspicuous (Fig. 11 ), 10Rp1 is the typical observed for this genus (Fig. 11 ). Hp narrow and elongate, apically depigmented, Lpp and Rpp almost subequal (Fig. 12 ). LC2 shorter than LC1, longitudinal ratio of LC1/LC2: 1.28 (Fig. 12 ). Variation. Some differences were observed between the specimens. The head of some paratypes have the sides behind eyes strongly convergent and the eyes are very large (e.g., OR = 0.34). Female. Unknown.
