( Figs 16–26 ) Diagnosis (Male). Hindwing M three–branched; phallobase with numerous small tripartite structures, similar to spines, heavily sclerotized, inserted in a membranous matrix; antero-mesal pair of the endophallic sclerites short, stout and arising in the middle of the phallosome; external parameres forked, with two pointed processes on the inner side. Color (of parts mounted on a slide). Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 16 ). Scape and pedicel brown, f1 pale brown, f2–f3 brown. Mx4 brown. Legs with coxae, trochanters and femora pale brown, tibiae and tarsomeres brown. Forewings almost hyaline ( Fig. 17 ); a small brown spot at confluence of Cu2–1A; veins brown. Hindwing ( Fig. 18 ), almost hyaline, veins brown. Morphology. Compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with four denticles markedly sclerotized ( Fig. 19 ). Forewing pterostigma elongate, constricted proximally, widest in the middle. Areola postica tall, broadly triangular, with apex rounded. Rs straight, R2+3 almost straight, R4+5 sinuous. M stem slightly concave proximally, then almost straight. M of five primary branches, M5 forked, resulting in M5a and M5b ( Fig. 17 ; see also variation of the paratypes below). Hindwing Rs-M joined for a distance, Rs, R2+3 and R4+5 almost straight, M3-branched ( Fig. 18 ; see also variation of the paratypes below). Hypandrium of one sclerite, almost straight anteriorly, antero-lateral corners with one concave area on each; posteriorly V shaped; setae as illustrated ( Fig. 20 ). Phallosome ( Fig. 21 ) with side struts proximally fused, posteriorly fused to external parameres, these stout, almost rounded, distally forked, with two pointed processes on inner side, forming an almost closed circle, enclosing a membrane with pores. Phallobase with numerous small tripartite structures, similar to spines, heavily sclerotized, inserted in a membranous matrix. Three pairs of endophallic sclerites; antero-lateral pair anteriorly wide, narrowing posteriorly, slightly curved inwards and acuminate apically; antero-mesal pair short, curved outwards, heavily sclerotized, proximally touching in the middle, almost rectangular, anteriorly and posteriorly ending in a pointed processes; posterior pair long, stout, wide basally, with sides narrowing posteriorly, distally curved outward, blunt ended, close to the ends of the external parameres. Paraprocts stout, broad, almost triangular, slightly concave proximally, sensory fields with 30–31 trichobothria on basal rosettes, setae as illustrated ( Fig. 22 ). Epiproct semi-elliptic; a long seta mesally near each side, other setae as illustrated ( Fig.22 ). FIGURES 16–22. Brasineura spinosa sp.n. (Holotype). 16. Front view of head. 17. Forewing. 18.

The specific name refers to the numerous spines of the phallosome. Variation of paratypes . 1 male with forewing M5 with three branches resulting in M5a, M5b and M5c ( Fig. 23 ). 1 male with left forewing M vein six branched, with M6 branched resulting in M6a and M6b ( Fig. 24 ); right forewing M vein five branched and M5 with three branches resulting in M5a, M5b and M5c; left hindwing with M2 branched resulting in M2a and M2b ( Fig. 25 ) and right hindwing with M3 branched resulting in M3a and M3b ( Fig. 26 ).
