Description, holotype male. Length: 16.4 mm. Width: 6.6 mm. Color: Piceous black. Head: Surface velvety shagreened, impunctate basally, anterior half of frons shagreened with fine, shallow punctures, becoming shiny near margins with larger punctures laterally. Clypeus short, emarginate on each side, apex acuminate with median denticle. Clypeolabral suture obsolete. Labrum bifurcate, visible dorsally, just below clypeus. Suprantennal tubercle weakly elevated but distinct, elongate. Ocular canthus broad, rounded, laterally produced, convex; canthus not contiguous with anterior and posterior margins of head; postocular process a large, compressed, transverse plate. Antennal club moderate, short (shorter than scape), antennomeres tomentose only distally. Mandibles (to true apex) shorter than head, apex triangular, internal tooth bifurcate. Dorsal surface produced into long, vertical ramus (false apex); ramus with apex truncate, conjoined to triangular subapical tooth, margin not serrate internally, basal lobe forming an obtuse tooth remote from smaller internal tooth. Mentum broad, distinctly emarginate, surface coarsely, contiguously punctate. Pronotum: Form broad, wider than elytra. Anterior angles transversely truncate. Surface smooth with minute punctures. Anteromedial tubercle small, anterior margin produced on either side. Elytra: Form subparallel, widest at middle. Surface with serially punctate striae, striae impressed basally (rugose at base) becoming weakly impressed towards apex, striae 7–9 almost obsolete except medially, striae very with regular sides without punctures crenulating intervals; strial punctures elongate. Intervals strongly convex basally, becoming flat towards apex, punctate with fine, shallow punctures in 3–5 irregular rows. Legs: Protibia with 7 acute teeth decreasing in size proximally. Mesotibiae and metatibiae with 1 large external tooth below middle with 1–3 smaller accessory teeth proximally. Abdomen: Male genitalia ( Fig. 16) with permanently everted internal sac (flagellum) whip-like, 45 mm.

Paratype variation. Males (n = 4). Length: 13.0– 16.1 mm. Width: 5.2–6.9 mm. Postocular process varying from compressed as in holotype to bulbous; reduced in smaller males. Females (n = 7). Length: 13.2–18.9 mm. Width: 5.2–6.9 mm. The females ( Fig. 14) differ from the holotype male in the following characters: Clypeal apex with median tooth larger. Labrum lower than clypeus, not distinctly visible in dorsal view. Suprantennal tubercles more strongly elevated. Antennal club smaller. Mandibles lacking dorsal ramus, subapical dorsal tooth moderately large, obtuse. Anteromedial pronotal tubercle strongly produced in large females.

Remarks. The strongly concave ocular canthus of females of this species is immediately recognizable ( Fig. 14). Males are somewhat less distinctive, but the elytral striae of the disc are narrower and have straight margins that are not crenulated by the punctures as in G. madagascariensis   and G. oberndorferi   . Etymology. The specific epithet is a shortened form of the type locality Zombitse with which I origi- nally labeled the specimens during the revision, and which gradually stuck. It is used as a noun in apposition based on an arbitrary (non-Latin) combination of letters.

Distribution ( Fig. 36 View Figures 33–37 ). MADAGASCAR   : MAHAJANGA: Forêt d’Ankarafantsika; Forêt de Tsimembo near Soatana; P.N. Tsingy de Bemaraha. TOLIARA: P.N. Zombitse.
