Material examined. Holotype (male): Thailand, Nakhon Ratchasima, Sakaerat Environmental Research Station, open area with light trap, dry evergreen, attracted to light trap, 400-450m, 13 September 2014, coll. P. Dawwrueng, N. Makbun & T. Dowwiangkan ( THNHM).

Paratype: 1 female, same locality and information as holotype ( THNHM).

Diagnosis. This species is very similar to Kuzicus aspercaudatus Sänger & Helfert, 2006  by median lobes of male tenth abdominal tergite long and slender, bent ventrad to form two lobes; and male epiphallus with apex minutely denticulated but differ by male tenth abdominal tergite with small lateral apical lobes (absent in K. aspercaudatus  ); median lobe of male tenth abdominal tergite with a row of smaller teeth along the ventral margin at the apex (instead of denticulated on the dorsal and posterior margins in K. aspercaudatus  ).

Description. Habitus typical of the genus ( Fig. 7View FIGURE 7 A, 7 B). Description similar to Kuzicus pakthongchai  sp. n. by rather large size, eyes globular and protruding. Fastigium verticis conical but with inconspicuous median sulcus ( Fig. 8View FIGURE 8 A). Last (apical) segment of maxillary palpus slightly shorter than the fourth (subapical) segment, also slightly widened apically ( Figs. 8View FIGURE 8 A, 8 B). Pronotal disc with anterior and posterior margin similar to Kuzicus pakthongchai  sp. n. and covering base of mirror tegmen ( Fig. 8View FIGURE 8 A). Margin of lateral lobes of pronotum slightly undulated ( Fig. 8View FIGURE 8 B). Thoracic auditory spiracle (= thoracic foramen) large and inverted pyriform ( Fig. 8View FIGURE 8 B). Parapterous, tegmen extending behind the hind knees, hindwings distinctly longer. Procoxal spur short. Meso- and metatibiae with 5 outer and 4 inner subapical spines.

Male. Tenth abdominal tergite with a pair of median lobes and lateral lobes. Median lobes long and slender; converge slightly towards one another in the middle before diverging apically, never in contact with one another; each broaden apically into a bulbous apex that contacts one another ( Figs. 8View FIGURE 8 C, 8 D). At the apex, median lobes bent ventrad to form two lobes: basal lobe smaller, produced with a small and slender external tooth; apical lobe larger, produced into a larger internal tooth with a row of smaller teeth along the ventral margin ( Figs. 8View FIGURE 8 D, 8 E). Lateral lobes of tenth abdominal tergite long and slender, reaching slightly before middle of median lobes, with apex obtuse ( Figs. 8View FIGURE 8 C, 8 D). Epiproct concealed under tenth abdominal tergite. Cerci with basal half swollen and robust, internally with a sclerotize spine-like process; then curve internally and taper into an acute and sclerotized apex ( Figs. 8View FIGURE 8 C, 8 F). Yoke-like epiphallus typical of the genus, but with distal appendages only ( Figs. 8View FIGURE 8 E, 8 G). Epiphallus transverse at the base, with a very short and broad shaft that widens posteriorly; at the apex with a pair of tooth-like sclerotized processes pointing posteriorly; and with fairly thick bristles. Posterior margin producing into a trilobous plate in the middle; with lateral lobe denticulated and heavily sclerotized ( Figs. 8View FIGURE 8 E, 8 G). Subgenital plate with styli relatively short and robust, gently curved outwards ( Fig. 8View FIGURE 8 E).

Female. Tenth abdominal tergite with posterior margin distinctly concave in the middle, truncated laterally; more deeply excised than Kuzicus pakthongchai  sp. n. in the middle ( Fig. 8View FIGURE 8 H). Epiproct and cerci similar to Kuzicus pakthongchai  sp. n. ( Fig. 8View FIGURE 8 H). Subgenital plate trapezoid ( Fig. 8View FIGURE 8 I). Ovipositor straight and very long, reaching apex of tegmen; with base slightly swollen ( Fig. 8View FIGURE 8 J). Valves smooth with acute apex; ventral valve forming a small hook at the apex ( Fig. 8View FIGURE 8 J). At the base, with two small sclerotized tooth ventrally ( Fig. 8View FIGURE 8 J).

Colouration. Unicolorous green when alive; white to ochre when preserved ( Figs. 7View FIGURE 7 A, 7 B). Tegmen also with some small rounded infumated brown spots throughout, randomly and widely distributed; with cells near posterior margin infumated dark.

Measurements. See Table 2.

Etymology. The species name refers to the numerous ventral teeth male at the apex of the median lobes of tenth abdominal tergite.
