Diagnosis. This new species is diagnostic for the subovate valva with an open base and having an oval pleat extending from base to apex on the inner surface.

Description. Adult ( Fig. 50 View FIGURES 44 − 51 ). Wingspan 8.5−11.5 mm. Head pale orange yellow. Antenna dusty yellow, 0.9× length of forewing; scape with a few black pecten bristles; flagellum unicolorous. Labial palpus dusty yellow, first and second segments with scattered darker scales on outer surface, third segment mixed with dark brown. Thorax and tegula yellowish brown. Forewing index 0.3, yellowish brown; retinaculum present; cilia yellowish brown, without cilia line. Hindwing grayish yellow; male with a single short, slender evenly curved frenular bristle, female with two same length bristles, thicker than male; cilia pale gray. Legs yellowish brown, fore and mid legs dark brown on ventral surface.

Pregenital abdomen. First tergum with medial 4/5 sclerotized. In male, coremata present in eighth segment; eighth sternite 0.25× as long as wide, posterior margin gently concave, without caudal process; eighth tergite tapered, without caudal process. In female, seventh sternite semicircularly concave at middle on posterior margin.

Male genitalia ( Fig. 79 View FIGURES 76 − 79 ). Vinculum with anterior and posterior margins parallel sided; medial process absent from ventrocaudal margin. Tegumen as deep as vinculum, slightly concave on anterior margin, convex at middle on posterior margin. Uncus with broad fan-shaped base that interrupted by traces of uncus lobes, not forming membraneous section with tegumen; uncus lobe 0.7× depth of vinculum, gently bent ventrad, only with sparse setae laterally, basal 3/4 fused, somewhat rectangular, distal 1/4 bifurcate, widely apart. Valva subovate, truncate at apex; costal margin semicircularly convex and bearing peg-like scales in basal half; basal flange absent; ventral margin gently convex, smooth, without ventral lobe; basal margin without ‘secondary apodeme’; inner surface with two transverse, parallel, apically joined pleats extending from base to before apex along middle section. Juxta angled caudally, short and slender, about 0.5× length of aedeagus. Aedeagus 1.5× length of valva, bullet-like; medial 1/3 membraneous, with a slender sclerotized band on ventral middle line, with two broader sclerotized bands laterally. Bulbus ejaculatorius 2.0× length of aedeagus, subdistal and distal sections not hypertrophied.

Female genitalia ( Fig. 94 View FIGURES 92 − 94 ). Ovipositor length 2.3−2.7 mm. Eighth tergite tapered, anterior margin convex in triangle; microtrichiate on posterior half, with sparse setae on posterior margin. Eighth sternite membraneous medially, sclerotized in torus shape postero-laterally, microtrichiate on posterior 2/3, with sparse setae on posterior margin. Ostium at middle of anterior membraneous half, with sparse setae. Antrum absent, ductus bursae broad, 2.5× length of corpus bursae. Colliculum comprising a skirt-like, apex-denticulate process arising from junction of ductus bursae and corpus bursae, invaginated into corpus bursae to level of second ring; second ring at basal 2/5 of corpus bursae, with anterior margin denticulate; inception of ductus seminalis dorsal, at posterior margin of second ring. Corpus bursae ovate, thick-walled in posterior 2/5; signum absent.

Distribution. China (Hainan, Guangxi).

Etymology. The specific name is derived from the Latin minutus, meaning small, referring to the small size of the new species.
