(Figs 1–11)
Diagnosis. This new species appears similar to Eusarima contorta Yang, 1994, but differs by: 1) Frons with a pair of curved eyelike markings on the disc (Fig. 4), but the latter species without these eyelike markings (Chan & Yang,1994, fig. 45B); 2) Capitulum of gonostylus thick and short, with tip obtuse (Fig. 9), but long and slender, with tip acute in E. contorta (Chan & Yang, 1994, fig. 45E); 3) Aedeagus with a pair of short hook-like processes (Fig. 10), but the latter species with a pair of extremely long processes (Chan & Yang, 1994, fig. 45H).
Etymology. This species name is a combination of Latin words “ macula ” and “ frons ”, referring to the light yellowish M-shaped markings on the frons.
Description. Length: male (including forewings) (N=4): 5.1–5.2 mm.
Coloration. Vertex brown, anterior, lateral and posterior margins all brown (Figs 1, 3). Compound eyes grayish brown, supported by grayish callus (Figs 1, 3). Frons brown, with an obvious light yellowish M-shape eyelike marking on the middle and some irregular yellow patches near base (Fig. 4); median carina brown from apex extending to near base, but not reaching to the frontoclypeal suture (Fig. 4); apical margin and lateral margins brown (Fig. 4). Antennae brown (Fig. 4). Postclypeus mainly brown, with light yellow near the base (Fig. 4). Gena brown, with one light yellow transverse fascia below compound eyes in lateral view (Fig. 2). Pronotum brown, anterior and posterior margins brown, median carina brown, only visible at middle (Figs 1, 3). Mesonotum brown, median and sublateral carinae all brown (Figs 1, 3). Forewings tawny to brown, longitudinal veins brown (Figs 1, 5). Hind wings brown (Fig. 6). Legs tawny, distributed with irregular brownish markings (Figs 2, 4).
Head and thorax. Vertex 1.5 times wider in midline than long in midline, lateral margins nearly parallel, slightly concave at middle (Figs 1, 3). Frons 1.0 times wider at widest part than long in midline, 1.6 times wider at widest part than apical margin (Fig. 4); lateral margins nearly parallel from the apex to the middle of compound eyes, then expand to below antennae and finally narrow to the base (Fig. 4); sublateral carinae weakly present or invisible (Fig. 4). Pronotum 3.0 times wider at posterior margin than long in midline, 1.0 times longer in midline than vertex (Figs 1, 3); median carina weakly present or absent, with a small incision on each side of midline (Figs 1, 3). Mesonotum with anterior margin 1.8 times wider than long in midline, 1.7 times longer in midline than pronotum, median carina visible from anterior margin elevated to the basal 1/4, sublateral carinae elevated from anterior margin to the posterior margin (Figs 1, 3). Forewings 2.2 times longer at longest part than widest part, CuA forking slightly after MP (Figs 2, 5), MP1+2 vein bifurcate at apical 1/6 (Figs 2, 5), MP3+4 vein forked at apical 1/6 (Fig. 2) or unforked (Fig. 5), CuA1 and CuA2 unforked (Fig. 5). Metatibiotarsal formula: (2)–7/(8-10)/2.
Male genitalia. Anal tube in lateral view curved downward near apex (Fig. 7), in dorsal view long cylindrical, widest at basal 1/3, 3.0 times longer in midline than widest part, apical margin rounded, lateral margins nearly parallel at apical half and convex at basal half (Fig. 8); anal opening located at basal 1/3 of anal tube (Fig. 8). Pygofer in lateral view long and slender, 2.6 times higher in midline than broad in midline, dorsal margin strongly sloping posterior, posterior margin convex at middle (Fig. 7); tectiductus large and broad (Fig. 7). Gonostylus in lateral view gradually broadened to apex, widest at apical 1/4, dorsal margin elevated at middle, then parallel with ventral margin; ventral margin deeply expand downward at basal 1/9 then straight with caudo-ventral angle subrectangular (Fig. 9). Capitulum of gonostylus directed cephalad, with an arc-shaped antero-lateral process on the base and a finger-shaped postero-lateral process at base (Fig. 9). Periandrium dorsal lobes slightly shorter than lateral lobes, the apical part laminar (Fig. 10). Periandrium lateral lobes in lateral view rounded in the apex (Fig. 10), in ventral view the median part deeply biforked (Fig. 11). Periandrium ventral lobe in lateral view rounded at apex (Fig. 10), in ventral view with apical margin rounded, lateral margins nearly parallel (Fig. 11). Aedeagus with a pair of short broad hook-like processes derived from apical 1/6, this pair of processes in lateral view curved downward then extending to the apical 1/3 of periandrium, tip pointed slightly surpassing the ventral margin (Fig. 10), in ventral view this pair of processes curved outward (Fig. 11)
