Length of male 3.6–3.8 mm; female 3.8–4.0 mm. Dorsum pale yellowish (Fig. 3 A – D View Figure 3 ); eyes brownish-grey; face yellowish (Fig. 3 E, F View Figure 3 ); margin of clavus in forewing blackish brown (Fig. 3 A, C View Figure 3 ).

Crown rounded anteriorly; coronal suture distinct and extending to middle of crown; width of head slightly less than greatest width of pronotum (Fig. 3 A, C View Figure 3 ); forewing with second apical cell largest and third apical cell subtriangular and petiolate (Fig. 4 B View Figure 4 ); hind wing gradually narrowed apically (Fig. 4 C View Figure 4 ).

Male genitalia. Pygofer with dorsal bridge short; pygofer lobe triangular-shaped, without appendage, with a variety of setae: basal region with a group of macrosetae, two rows of microsetae across lobe subapically and several fine setae and macrosetae at posterodorsal region (Figs 3 G View Figure 3 , 4 A View Figure 4 ). Subgenital plate gradually narrowed towards apex, with distal third abruptly curved dorsad; with one basal macrosetae, row of peg-like setae on lateral margin extended to apex, with several scattered fine microsetae (Figs 3 I View Figure 3 , 4 D View Figure 4 ). Style tapered distally to acute apex with subapical dilation, with row of microsetae on lateral margin (Figs 3 H View Figure 3 , 4 E View Figure 4 ). Connective elongate, Y-shaped, central ridge well developed (Fig. 4 F View Figure 4 ). Aedeagus with both preatrium and dorsoatrium well developed, shaft slightly curved dorsally and tapered to narrow apex, with two pairs of elongate processes at apex and two small subapical tooth-like processes on ventral surface (Figs 3 J – L View Figure 3 , 4 I View Figure 4 ); dorsal margin of longer processes in lateral view with or without a tiny tooth (Figs 3 L View Figure 3 , 4 I View Figure 4 ), gonopore apical (Fig. 4 I View Figure 4 ).

Diagnosis.

This new species is similar to Edwardsiana ishidai (Matsumura, 1932) and E. rosae (Linnaeus, 1758) , but it can be distinguished by the dark brown inner margin of the forewing and aedeagal processes not bifurcate.

Etymology.
