Description of the holotype.

Coloration. – Integument mostly dark brown; palpomeres dark yellowish brown; scape dark reddish brown, darker on apex; pedicel mostly brownish; antennomeres III–XI orangish brown, darkened apically. Prosternum with irregular dark reddish brown area centrally. Central area of mesoventrite and mesoventral process dark reddish brown; central area of metaventrite with irregular reddish brown areas. Elytra gradually brown toward apex. Pro- and mesocoxae mostly orangish brown; trochanters and femoral peduncles orangish brown; femoral peduncles mostly brown, darker on profemora. Tibiae reddish brown basally, gradually darkened toward apex, especially on apical quarter. Tarsomeres I dark reddish brown basally, blackish apically; tarsomeres II–V blackish. Abdominal ventrite 2–4 dark reddish brown apically; ventrite 3 with yellowish-brown maculae centrally near apex; ventrite 5 with irregular reddish-brown maculae, especially on posterior half.

Head. – Frons finely, abundantly punctate; with ochraceous pubescence almost obscuring integument, except glabrous region of median groove, and one long, erect dark brown seta on each side close to clypeus. Vertex finely punctate, except smooth area close to prothorax; with dense ochraceous pubescence obscuring integument, except glabrous area close to prothorax and area of median groove (this latter area diamond-shaped between antennal tubercles and upper eye lobes). Area behind eyes with ochraceous pubescence obscuring integument close to eye, pubescence narrowed toward area between eye lobes, widened, yellower toward ventral surface, glabrous close to prothorax. Genae with dense yellowish-brown pubescence, except glabrous apex. Wide central area of postclypeus with pubescence as on frons posteriorly, sparser, bristly close to anteclypeus; with one long, erect seta on each side, blackish basally, gradually yellowish toward apex. Labrum with sparse ochraceous pubescence, and long, erect setae interspersed on posterior half, setae blackish basally, gradually yellowish toward apex; anterior margin with fringe of yellowish setae. Gulamentum smooth, glabrous on wide posterior area, finely punctate, with sparse, moderately long, erect yellowish setae anteriorly. Distance between upper eye lobes 0.27 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.57 times distance between outer margins of eyes. Antennae 3.2 times elytral length, reaching elytral apex at basal sixth of antennomere VI. Scape with abundant yellowish-white pubescence not obscuring integument, and a few short, erect, thick black setae ventrally near apex; pedicel with pubescence as on scape, and a few short, erect black setae on ventral surface of posterior half; antennomeres III–XI with sparse yellowish pubescence, slightly denser and bristly toward XI; antennomeres III–IV with a few short, erect black setae ventrally; antennomeres III–IX with short, erect black setae apically.

Antennal formula based on length of antennomere III:

– Scape = 1.55. – Pedicel = 0.09. – IV = 1.55. – V = 1.55. – VI = 1.45. – VII = 1.36. – VIII = 1.36. – IX = 1.36. – X = 1.36. – XI = 1.27.

Thorax. – Prothorax wider than long; sides gradually widened from anterolateral angles to near posterior third, slightly convergent from this point to lateral tubercles, then distinctly narrowed toward posterolateral angles; lateral tubercles located near posterolateral angles, with blunt apex not directed backward. Pronotum coarsely, abundantly punctate; with moderately large, circular brown pubescent spot on each side of anterior third, brownish pubescent macula on middle of lateral margins, yellow pubescent band on lateral margins close to lateral tubercle, mostly pale yellow pubescence on wide central area, and mostly yellowish-white pubescence on remaining surface; with a few long, erect blackish setae near lateral tubercle. Sides of prothorax coarsely, abundantly punctate; with grayish-white pubescence partially obscuring integument. Prosternum and prosternal process with grayish-white pubescence not obscuring integument; narrowest area of prosternal process 0.2 times procoxal width. Mesoventrite with short grayish-white pubescence distinctly not obscuring integument, almost absent on each side of anterocentral region, longer, denser laterally; mesanepisternum and mesepimeron with dense white pubescence; metanepisternum and sides of metaventrite with dense yellowish-white pubescence; central area of metaventrite with minute, abundant yellowish-white pubescence not obscuring integument. Scutellum with dense grayish-white pubescence.

Elytra. – Somewhat coarsely, abundantly punctate, punctures gradually finer and sparser from middle, especially on posterior third; basal area with dense grayish-yellow pubescence; remaining surface most with dense grayish-white pubescence, not reaching epipleural margin and apex, longitudinally projected on sides before and after middle, with circular brownish pubescent spots interspersed, except large, irregular brownish pubescent macula on sides of central area, and another irregular spot (more irregular than the former) on posterior third, laterally fused with brownish pubescent apex; area of centrobasal crest slightly tumid; apex obliquely truncate, except straight narrow area close to sutural angle.

Legs. – Femora with abundant grayish-white pubescence not obscuring integument; metafemora distinctly surpassing elytral apex. Protibiae with grayish-white pubescence not obscuring integument, except posterior 2/3 of ventral surface with darker pubescence, and short, thick, erect setae, more distinct close to apex of anterior third. Mesotibiae with abundant grayish-white pubescence not obscuring integument, except slightly distinct dark pubescence on apical third, and short, erect, abundant, thick black setae on dorsal surface of apical third; metatibiae with sparse yellowish pubescence, darker apically, and short, erect, thick black setae interspersed. Metatarsomere I 4.0 times II–III together.

Abdomen. – Ventrites with abundant grayish-white pubescence not obscuring integument, slightly denser and longer laterally, except glabrous yellowish-brown area of ventrite 3. Apex of ventrite 5 emarginate centrally.

Etymology. – Greek, “leptos ” (λεπτός), meaning slender, slim, and thin; alluding to the body shape of the new species.

Remarks. – Anisopodus leptos sp. nov. is similar to A. andicola Kirsch, 1889 (see photographs on Bezark 2022), but differs by the elytral apex not spiniform (outer angle distinctly spiniform in A. andicola ), grayish-white pubescence on the elytra not reaching apex (reaching the apex in A. andicola ), and circular brownish spots on the elytra distinctly larger (very small in A. andicola ). It differs from A. degener Bates, 1885 (see photographs on Bezark 2022), especially by the metafemora distinctly longer and slender (shorter, thicker, not surpassing the elytral apex in males of A. degener ); from A. dispar Bates, 1885 (see photographs on Bezark 2022), by the lateral tubercles of the prothorax not spiniform and not directed backward (spiniform and directed backward in A. dispar ), and by the metafemoral club not abruptly widened (abruptly widened in A. dispar ); and from A. punctipennis Monné & Martins, 1976 (see photographs on Bezark 2022) by the slender body (stouter in A. punctipennis ), and by the metafemoral club slender and longer (stouter and shorter in A. punctipennis ).
