MATERIAL. Holotype ♂ ( ZMMU) and paratypes ( SIEE), ♂, 2♀♀, with labels: ‘ Vietnam, Thanh Hoa Prov [ince]./ Thach Thanh District ,/ 20°17′39″N 105°33′24″E / forest trail/ h~ 50– 70 m, 16–26.IV.2024 / D. Fedorenko leg.’; ♀ ( ZISP), ‘ ДРВ / КУК- Фыонг, Нин- Бинь / первичный Лес / Захаров 3.1.71 ’ [ Vietnam, Cuc Phuong, Nin Binh Province, primary forest, 3.I.1971, A. Zakharov leg.]. — Aedeagus examined in two males, including one with everted and inflated internal sac. GoogleMaps

DIAGNOSIS. An apterous black species most similar to the previous one in appearance, from which it is distinguished chiefly by a distinctive aedeagus, the elytral ridges equally developed, with the pubescence much less differentiated between odd and even intervals, the head smaller, PW/HW 1.24–1.32 (vs. 1.14–1.25), with the genae distinctly shorter, GL/OL 1.08–1.21 (vs. 1.25–1.46), and the elytra longer in male, EL/ EW 1.78–1.89 (vs. 1.72–1.80).

DESCRIPTION. As for G. linearis sp.n. except the following. BL 23.6–24.8 mm. Body ( Fig. 13 View Figs 13–15 ) black, with no reddish spots. Antennae black, mostly slightly reddish toward apices. Forebody with microsculpture superficial, more distinct toward sides of pronotum.

Head with frontal carina long though less distinct, flat and punctate behind, with no impression on vertex.

Pronotum with sides very slightly diverging to (mostly) barely converging to base; basal angles blunt, right or very slightly obtuse. Base truncate, apex slightly sinuate and straight at middle. Disc moderately convex, rather finely and confluently punctate, rugose-punctate along base and along sides in apical third. Basolateral foveae and sublateral line less distinct to nearly indistinct.

Elytral apices similar except that sutural angle mostly sharp and outer angles less distinct. Pubescence sparser, so that two rows of setae on each side of even ridges are traceable throughout the ridges in one specimen and in basal third to half in the other three; differences between even and odd interval in pubescence otherwise are due to one-row setae are much denser on sides of the former than of the latter.

Aedeagus ( Figs 42–43 View Figs 32–43 , 63 View Figs 44–65 , 99–101 View Figs 96–101 ): apex of median lobe in lateral view triangular, with slightly obtuse dorsal tooth, very finely and densely striated on each side of a narrow ventromedial groove bearing a fine and fairly long carina at bottom. Left paramere nearly parallel-sided, slightly narrower apically than basally, with apex widely rounded. Internal sac with a single, right, laterobasal bulb, twelve dorsomedial and seven left lateral sclerites.

DISTRIBUTION. Known from the type locality only.

NAME. Refers to the underdeveloped fasciated elytral pattern.

HABITATS AND HABITS. The specimens were hand collected at night, running on the ground in a disturbed lowland rainforests.
