Diagnosis. This species is similar to Irepacma weishana WANG et LI, 2002 , but differs from it by the following characters: wings completely black, without any markings; in the male genitalia, sacculus without distinct ventral process, distal process longer and aedeagus not truncate at apex.

Description: Adult ( Fig. 3 ). Wingspan 17.5 mm in male. Head orange yellow except for vertex shining white, posterior area tinged yellowish brown. Labial palpi orange yellow, ventral surface tinged black in distal 1/3. Antennae with scape yellow, flagella black. Thorax, tegulae and wings evenly black. Legs whitish yellow, tibiae and tarsi with grayish rings or patches.

Male genitalia ( Fig. 7 ). Uncus quite small, nearly trapezoidal, sparsely with long hairs. Gnathos an irregularly rounded circle, weakly sclerotized. Tegumen relatively long and narrow, with posterior half somewhat trapezoidal, deeply concave at middle of anterior margin, laterally extended, bent inward distally. Valvae narrowed basally, distal half widened and nearly parallel-sided, finely haired; costa naked and strongly sclerotized, basal half arched inward; process at dorso-proximal corner thick, heavily sclerotized, almost as long as tegumen, distal portion with strong spines. Sacculus sclerotized, basal portion broad, middle portion thin and strongly curved, distal portion broad lanceolate. Saccus short, more or less triangular in shape. Juxta large, elliptical. Aedeagus with basal 1/3 quite thin, distal 2/3 thick, with a rounded process near apex.

Female: Unknown.

Distribution: China (Hubei).

Etymology: The name is derived from the Latin lanceolatus (lanceolate), to note the shape of the distal portion of sacculus.
