Description. Habitus as in Fig. 25B . Length 13.2–16.2 mm; humeral width 6.2–8.7 mm. Color dark reddish brown. Head: Frons coarsely rugopunctate, area between eyes nearly smooth. Frontoclypeal region with 2 tumescences ( Fig. 2D ). Clypeus trapezoidal, base 1.5 times as wide as apex; apical angles acute ( Fig. 2D ). Clypeal teeth conical, widely separated (1.5 times a tooth diameter) ( Fig. 2D ). Mandible with 2 apical and 1 lateral acute large tooth, the first apical tooth small and joined to the second. Interocular distance equal to 3 times an eye width. Antennal club long, 1.5 times longer than antennomeres 2–7. Pronotum: Surface with minute, sparse punctures. Apical tubercle inconspicuous, rounded. Fovea small, as a shallow concavity behind tubercle ( Fig. 2D ). Elytra: First interval punctate, punctures similar in other intervals. Inner surface of apex with transverse, small tubercles forming 160 parallel lines. Abdomen: Apex of tergite IV with a diagonal line of 14 short, transverse, parallel carinae; carinae slightly wider at middle. Pygidium with large, dense, evenly distributed punctures. Strongly (male) to slightly (female) convex in lateral view. Legs: Protibia tridentate without an additional small basal tooth. Protarsus simple; inner claw simple. Metatibia not narrowed before apex, sides nearly parallel. Apex of metatibia slightly crenulate, with 10–14 spinules. Male genitalia: Spiculum gastrale with apex straight. Parameres with sides nearly parallel, slightly contracted at the apical 4th, apexes outwards, ventral margin with a small apical tooth ( Figs. 15E , 17E ).

Diagnosis. Ligyrus moroni and L. cuniculus are similar in general appearance, shape of the mandible, tumescences on head, and small pronotal fovea and tubercle. However, L. moroni has the clypeal apical angles acute (rounded in L. cuniculus ), the clypeal teeth conical (triangular to transverse in L. cuniculus ), and the parameres with a small apical ventral tooth ( Fig. 15E ), not present in L. cuniculus ( Fig. 15D ).

Distribution. Southern Atlantic coast of Brazil in the states of Rio de Janeiro, São Paulo, Santa Catarina, and probably Paraná.
