Magadha basimaculata sp. nov.

( Figs 1–16 )

Measurements. Body length (from apex of vertex to tip of forewing): male 5.1–6.0 mm (n = 49), female 6.0–7.0 mm (n = 20); forewing length: male 4.3–5.1 mm (n = 49), female 5.0–6.0 mm (n = 20).

Coloration. Greyish white to brown. Head, pronotum, mesonotum, and tegula brown with numerous pale yellowish brown dots ( Figs 1–7 ). Eyes reddish brown, ocellus pale yellowish brown ( Figs 1–7 ). Forewing greyish white, with differently sized brown to dark brown markings, with one broad dark brown marking across base ( Figs 1–4 , 8 ). Hindwing pale brown, veins dark brown. Legs light brown. Abdomen dark brown.

Head and thorax. Width of vertex at base to length in midline 2.0. Ratio length of frons in midline to maximum width 1.2, ratio maximum width to width at base 1.7. Ratio length of postclypeus in midline to length of frons 0.8. Ratio of apical to subapical segment of rostrum 1.5. Ratio length of pronotum in midline to length of vertex 0.7. Mesonotum in midline 6.4 times longer than pronotum, 2.6 times longer than pronotum and vertex combined. Forewing with ratio of length to maximum width 3.0. Hindwing with ratio of length to maximum width 1.8.

Male genitalia. Anal segment in dorsal view relatively short ( Fig. 10 ), with ratio length to maximum width 0.5, apical margin distinctly concave; anal stylet large, epiproct broad with apical margin just reaching apex of anal segment. Pygofer in lateral view ( Fig. 11 ) with dorsal margin distinctly longer than ventral margin, narrowest part at ventral third, anterior margin broadly concave, posterior margin slightly concave; in ventral view ( Fig. 12 ), medioventral process of pygofer entire, with apical margin roundly convex. Genital style with apex angularly convex, dorsal margin rising from 2 sharp bent processes and 1 blunt straight process; inner surfaces near base with 1 fingerlike process, directed basad ( Fig. 13 ). Aedeagus with phallobase sheath-shaped, symmetrical ( Figs 15–16 ); in dorsal view ( Fig. 15 ) dorsal lobe shorter than the ventral, with apical margin cleft in the middle, bilateral margin with apical half rising, rolled-up dorsad; in ventral view ( Fig. 16 ) ventral lobe with apical margin incised in middle, each side of midline with a row of teeth; in lateral view ( Fig. 14 ) apical half of phallobase only divided into ventral and dorsal processes, lateral lobes obsolete; ventral lobe with margin serrated, and the apex of dorsal lobe truncate.

Etymology. The species name is derived from the Latin words “ basis ” and “ maculatus ”, which refers to the big transverse dark mark at the base of the forewing ( Fig. 8 ).

Distribution. China (Guangxi, Guizhou and Hainan).

Remarks. Magadha basimaculata is similar to M. formosana but differs from the latter in: forewing with one big transverse dark mark at base (no such marking in M. formosana ); phallobase in lateral view with posterior half divided into 2 lobes (3 lobes in M. formosana ), and in dorsal view with lateroapical margin rolled-up dorsad (not rolled-up in M. formosana ).
