MATERIAL. Holotype ♂ ( ZMMU), labelled: ‘S[outhern] Vietnam, Lam Dong Prov [ince]./ Bi Doup — Nui Ba [Nature] Reserve / 12°07′[N] 108°39′20″E / Bi Doup Mt. , N [orthern] slope/ h= 1700–1900 m 16./ leg. D. Fedorenko IV.2008 ’. Paratypes ( SIEE): ♂, taken together with the holotype; 3♂♂, ♀, same locality, except for different dates: 12. or 16., or 19–22. IV.2008 , or 6. V.2009; ♂, ♀, same locality, except for: ‘…/ 12°11′[N] 108°42′E, ~ 4 km / SSE of Hon Giao Mt. / h= 1500– 1800 m, 2-3./ leg. D. Fedorenko IV.2008 ’; ♀, same locality, except for ‘…// 12°10′44″N 108°40′44″E / env. Long Lanh, h GoogleMaps = 1400–1600 m 3-6./ …’; 4♂♂, 2♀♀, same data but different dates: 1–2. GoogleMaps V.2009 or various dates between 29.III. and 20–21. IV.2008; six specimens ( ZISP) from just the same exact locality, with labels ‘ VIETNAM: Lam Dong Prov.,/ Lac Duong Distr., 5 km NE/ Long Lanh Vill., Bi Doup — Nui/ Ba Nat. Res. , Giang Ly / Forest Station , 1400 m,’ and ‘ 12°10′58.62″N / 108°40′48.96″E,/ 29.VI-4.VII.2022 GoogleMaps ,/ Anisyutkin L.N. ( Expedition of Russia-Vietnam Tropical Centre )’. — Aedeagus examined in six males, including three with everted and inflated internal sac .

DIAGNOSIS. An apterous black species, with the genae long, the odd elytral ridges more developed than even ones, and the aedeagus is distinctive. Just as black morph of G. dimorpha sp.n., except chiefly that the pronotum is broadest closer to apex, PLw/PL 0.24–0.33 (vs. 0.37–0.43), genae longer, GL 1.30–1.45 (vs. 1.17–1.32), and the elytra distinctly shorter in male, EL/EW 1.65–1.78 (vs. 1.78–1.83). For other features see the description.

DESCRIPTION. As for G. dimorpha sp.n. except the following. BL 21.8–23.8 mm. Body ( Fig. 16 View Figs 16–18 ) uniform black. Forebody shinier due to punctation being barely coarser and slightly sparser, combined with microsculpture more superficial.

Shallow impression on vertex more distinct because of sparser and/or finer punctation around.

Pronotum broadest slightly more than a fourth from apex, densely to rather sparsely punctate on disc, densely to confluently along sides, rugose-puncate in basal sixth and just inside fine lateral bead. Sides sinuate and running parallel to each other in front of or diverging toward base. Base truncate, with angles straight to slightly acute, mostly blunt, sometimes narrowly rounded. Basolateral foveae in form of fine longitudinal lines, each extended apicad into a similar sublateral line, separating between convex disc and slightly yet widely (in lateral third) explanate lateral margin; often an additional, narrow, explanate stripe being traceable inside lateral bead. Median line fine, slightly impressed.

Elytral apices obliquely truncate, very slightly angulate combined, each straight in female, barely sinuate just inside outer angle in male; sutural angle slightly acute to nearly right, sharp or blunt. Interval 3 with three discal setae, odd ridges with much shorter, multiple, sparse, erect setae. Pubescence very sparse.

Aedeagus ( Figs 32–33 View Figs 32–43 , 52 View Figs 44–65 , 78–80 View Figs 78–83 ): left paramere elliptic, with both dorsal and ventral margins rounded toward apex. Internal sac as in G. dimorpha sp.n., i.e., with two laterobasal bulbs and a similar number of dorsomedial (nine) and left lateral (5–6) sclerites present, but it is oriented as those of

G. rufofemorata sp.n. and of many other species; ventrobasal sclerite distant rather far from apex of median lobe.

DISTRIBUTION. Known from the type locality only.

NAME. Refers to the odd elytral ridges varying between subequal to and better developed than the even ones.

HABITATS AND HABITS. All the specimens were hand collected under covers, mostly logs on the ground, in monsoon forests.
