Magadha densimaculosa sp. nov.

( Figs 17–32 )

Measurements. Body length (from apex of vertex to tip of forewing): male 5.0– 5.8 mm (n = 102), female 6.0– 6.7 mm (n = 55); forewing length: male 4.1–5.0 mm (n = 102), female 5.1–5.7 mm (n = 55).

Coloration. Brown to fuscous. Head, pronotum, mesonotum and forewing densely covered with small ivorywhite to yellow brown spots ( Figs 17–24 ). Eyes reddish brown, ocellus pale red. Hindwing pale brown, veins dark brown. Rostrum and legs brown. Abdomen dark brown.

Head and thorax. Ratio width of vertex from base to length in midline 2.0. Ratio length of frons in midline to maximum width 1.3, 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 1.4. Ratio length of pronotum in midline to length of vertex 0.7. Mesonotum in midline 6.5 times longer than pronotum, 2.7 times longer than pronotum and vertex combined. Forewing with ratio of length to maximum width 2.8. Hindwing with ratio of length to maximum width 1.8.

Male genitalia. Anal segment in dorsal view ( Fig. 26 ) with ratio length to maximum width 0.6, apical margin distinctly concave, epiproct with apical margin slightly incised in the middle and slightly exceeding apical margin of anal segment. Pygofer in lateral view ( Fig. 27 ) with dorsal margin longer than ventral margin, with the narrowest part in the middle, anterior margin broadly concave; in ventral view ( Fig. 28 ), medioventral process of pygofer entire and narrow, with apical margin subangularly convex. Genital style relatively broad, with apex roundly convex, dorsal margin rising from 2 broad processes; inner surfaces near base with one long bent process, directed outwards ( Fig. 29 ). Aedeagus with phallobase sheath-shaped, symmetrical ( Figs 30–31 ); in the dorsal view ( Fig. 30 ) dorsal lobe distinctly shorter than the ventral, and with apical margin cleft in the middle, bilateral margin rolled-up dorsad; in the ventral view ( Fig. 31 ) ventral lobe with apical margin incised in the middle, each side of midline with a row of teeth; in lateral view ( Fig. 32 ) the longest to the shortest lobes respectively: the ventral, the dorsal and the lateral; ventral lobe with most parts of margin serrated and the apex of dorsal lobe truncate.

Etymology. The species name is derived from the Latin words “ densus ” and “ maculosus ”, which refers to the body densely covered with small indistinct spots.

Distribution. China (Guizhou).

Remarks. Magadha densimaculosa resembles M. formosana , but differs from the latter in: forewing brown, with numerous ivory-white to tawny dots (forewing ivory-white, with variegated dark brown marks, and one broad dark brown band across middle third in M. formosana ); epiproct of anal segment with apical margin slightly incised in the middle and slightly exceeding apical margin of anal segment (epiproct with apical margin subtruncate and not exceeding apical margin of anal segment in M. formosana ); phallobase in dorsal view with lateroapical margin rolled up dorsad (not rolled up in M. formosana ).

Magadha densimaculosa is also similar to M. basimaculata but differs from the latter in: forewing brown, with dense small ivory-white spots (forewing ivory-white, with one broad dark brown marking across base in M. basimaculata ); genital style in dorsal view broad, dorsal margin with 2 processes (narrow, 3 processes in M. basimaculata ); phallobase in lateral view with apical half divided into 3 lobes (2 lobes in M. basimaculata ).
