Magadha intumescentia sp. nov.

( Figs 33–50 )

Measurements. Body length (from apex of vertex to tip of forewing): male 7.1 mm (n = 1), female 7.1–7.8 mm (n = 4); forewing length: male 6.1 mm (n = 1), female 6.1–6.6 mm (n = 4).

Coloration. Ivory-white to fuscous ( Figs 33–39 ). Vertex yellowish brown, with 2 fuscous markings at lateral margins ( Fig. 37 ). Frons fuscous, with 7 small ivory-white markings along lateral margin, base almost ivory-white, along median carina with irregular ivory-white markings, the largest marking near frontoclypeus suture ( Fig. 39 ). Postclypeus with basal half ivory-white and apical half brown ( Fig. 39 ). Genae fuscous, with 3 areas ivory-white as in Fig. 38 . Eyes dark brown, ocellus ivory-white. Antennae and rostrum brown. Pronotum fuscous, except for area between lateral carinae, angle at ventral margin and 4 longitudinal bridges on the lateral lobe ivory-white ( Fig. 37 ). Tegula with dorsal half pale yellowish brown and ventral half fuscous ( Figs 34, 36–37 ). Mesonotum mainly fuscous ( Fig. 37 ), posterior two-thirds between lateral carinae with pale yellow dots. Forewing with basal twothirds opaque and apical third subdiaphanous, basal third mainly dark brown, middle third almost ivory-white, and apical third mainly pale gray ( Figs 33–36 , 40 ). Hindwing pale brown, veins dark brown. Legs brown, with apex of femur and base of tibiae pale yellowish brown. Abdomen dark brown.

Head and thorax. Ratio width of vertex from base to length in midline 1.8. Ratio length of frons in midline to maximum width 1.4, ratio maximum width to width at base 1.9. Ratio length of postclypeus in midline to length of frons 0.6. Ratio of apical to subapical segment of rostrum 1.5. Pronotum relatively short, lateral lobe with 4 longitudinal bridges, ratio length of pronotum in midline to length of vertex 0.6. Mesonotum in midline 7.5 times longer than pronotum, 2.8 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. 42 ) with ratio length to maximum width 1.2, apical margin broadly concave, lateroapical margin concave. Pygofer in lateral view ( Fig. 43 ) with dorsal margin distinctly longer than ventral margin, the narrowest part at ventral third, anterior margin broadly concave; in ventral view ( Fig. 45 ), medioventral process of pygofer entire and rectangular, with ratio length to width 1.8, along midline almost convex. Genital style distinctly longer than wide, with apex narrow, apical two-thirds of ventral margin relatively straight, 2 small processes arising from centre of dorsal margin and 1 larger process from near base of dorsal margin; inner surfaces near base with 1 fingerlike process, directed outwards ( Fig. 46 ). Aedeagus with phallobase sheath-shaped and incompletely symmetrical ( Figs 47, 49–50 ); in dorsal view ( Fig. 47 ) dorsal lobe shorter than 2 lateral lobes, and with 2 processes rising from apical third, directed basad, the left process with one short blunt process and 2 spines at base, and the right one with only one sharp short process at base, the 2 lateral lobes bent toward each other apically; in ventral view ( Fig. 48 ) ventral lobe slightly shorter than the lateral, with apical margin deeply cleft in the middle and with inside margins slightly carinal ventrad and shagreen at base. Suspensoria distinctly intumescent near anal segment ( Figs 43, 44 )

Type material. Holotype: ♂, CHINA, Guizhou: Wangmo, Dayi, 21–22 Aug. 2012, S.-Y. Xu. Paratypes, Guizhou: 2 ♀♀, same data as holotype; 1 ♀, Dayi, Wangmo, 21–22 Aug. 2012, W.-C. Yang; 1 ♀, Dayi, Wangmo, 21–22 Aug. 2012, W.-B. Zheng.

Etymology. The species name is derived from the Latin words “ intumescentia ”, which indicates suspensoria distinctly intumescent ( Fig. 44 ).

Distribution. China (Guizhou).

Remarks. Magadha intumescentia is similar to M. pinnata but differs from the latter in: mesonotum dark brown (grayish brown in M. pinnata ); anal segment of male in dorsal view with lateroapical margin concave (lateroapical margin round convex in M. pinnata ); phallobase in dorsal view with dorsal lobe with only 2 small processes near the middle (with 2 large and 2 small processes in the middle in M. pinnata ), in ventral view with ventral lobe with apical margin deeply cleft in the middle (apical margin slightly incised in the middle in M. pinnata ).
