Diagnosis. This species is distinguished from the other species of Gracilaclopus by the following combination of characters: labral apex deeply indented in middle; head black, body light brown with scutellum same color as elytra (light brown); pronotum with a transversal row of setae in middle on each side of disc, setae sparse, long; size <5 mm; male genitalia as Fig. 24 View FIGURES 23 – 30. 23 .

Description. Holotype male. Length 4.07 mm, width 1.57 mm. Color: Head black, pronotum and elytra light brown; legs, antennae, and mouthparts brown; ventral surface brown. Head ( Fig. 8 View FIGURES 8 – 9 ): Frons flat on apical half, convex at base, surface sparsely punctate, glabrous. Clypeus strongly transverse; lateral margins oblique; anterior margin straight, slightly reflexed, frontal area of anterior margin oblique; frontoclypeal suture obsolete, surface densely punctate. Labral shape subrectangular in dorsal view apex strongly indented in middle, strongly reflexed, glabrous. Pronotum ( Fig. 9 View FIGURES 8 – 9 ): Surface sparsely punctate, with one row of sparse setae on each side of disc; setae long, slender. Marginal bead present in all margins, reduced on posterior margin at middle. Anterior angle nearly right-angled; posterior angles broadly rounded. Scutellum: Triangular , apex rounded, surface punctate at base, smooth at apex. Elytra: Surface punctate, punctures sparse, setose, setae moderately long. Legs: Mesotibiae and metatibiae with two transverse carinae. Mesotibial and metatibial apex with fringe of spine-like setae. Male genitalia ( Fig. 24 View FIGURES 23 – 30. 23 ): Parameres las long as phallobase, curved at middle; apex rounded not club-like.
