Head. Frons and area between antennal tubercles and upper eye lobes minutely, abundantly punctate; with abundant pale yellowish-brown pubescence not obscuring integument (yellower toward dorsal surface), except glabrous T-shaped area centrally, starting between lower eye lobes (longitudinal region), ending between antennal tubercles and upper eye lobes (transverse region); with a few long, erect brownish setae close to eyes; remaining surface of vertex with sparse reddish brown pubescence.

Genae with pale yellow pubescence not obscuring integument, and a few long, erect dark setae interspersed, except glabrous apex.

Sides of postclypeus glabrous. Labrum coplanar with anteclypeus, only inclined at narrow apical area; with sparse yellowish-white pubescence basally, glabrous on remaining surface, except apex with fringe of short yellow setae; with transverse row of long, erect dark brown setae about middle. Gulamentum smooth, glabrous, except narrow, depressed anterior area with a few long, erect dark setae. Distance between upper eye lobes 0.27 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.49 times distance between outer margins of eyes. Antennae 3.0 times elytral length, reaching elytral apex on basal third of antennomere VI; with yellowish-white pubescence not obscuring integument, slightly whiter toward apical segments; ventral apex of scape, pedicel, and antennomeres III–V with moderately long, erect, thick black setae ventrally, sparser toward V; apex of antennomeres IV–VIII with short, thick black setae. Antennal formula based on length of antennomere III: scape = 1.17; pedicel = 0.11; IV = 1.09; V = 0.97; VI = 0.97; VII = 0.91; VIII = 1.00; IX = 0.94; X = 0.88; XI = 0.91.

Prothorax wider than long; sides rounded from anterolateral angles to lateral tubercle placed on posterior 1/10, then abruptly narrowed toward posterolateral angles; apex of lateral tubercles acute. Pronotum moderately finely, sparsely punctate, except transverse row of coarse punctures near posterior margin; with abundant yellow pubescence not obscuring integument, shorter and sparser on some areas, except yellowish-brown pubescence on center of dark macula, and brown pubescence on sides of this macula. Sides of prothorax with abundant yellowish-brown pubescence partially obscuring integument, except brownish pubescence on dark oblique macula. Prosternum with abundant pale yellow pubescence not obscuring integument. Anterior half of prosternal process with abundant pale yellow pubescence not obscuring integument, sparser on posterior half, especially laterally; narrowest area 0.25 times procoxal width. Sides of mesothorax with abundant yellowish-brown pubescence, and central area with sparser pale yellow pubescence. Metanepisternum with abundant yellowish-brown pubescence not obscuring integument.

Scutellum with pale yellow longitudinal pubescent band centrally, with brownish pubescence on remaining surface. Elytra. Coarsely, moderately sparsely punctate; with abundant pale yellow pubescence partially obscuring integument, except brownish pubescence on dark dorsal areas, and yellowish-brown pubescence on dark anterolateral area; apex obliquely truncate, slightly concave between outer and sutural angles. Legs. With yellowish-white pubescence not obscuring integument, except dark area of tibiae with bristly, dark pubescence, denser on ventral surface of protibiae; mesotibiae with tuft of black setae close to dorsal sulcus; meso- and metatibiae with short, thick black setae, more abundant on metatibiae. Metatarsomere I much longer than II–III together.

Abdomen. Ventrites with abundant yellowish-white pubescence not obscuring integument; posterior area of ventrite 5 with long, thick dark setae.

Dimensions (mm) (Holotype female). Total length, 6.95; prothoracic length, 1.35; anterior prothoracic width, 1.45; posterior prothoracic width, 1.70; maximum prothoracic width, 2.00; humeral width, 2.50; elytral length, 4.95.

Type material. Holotype female from FRENCH GUIANA: Amazone Nature Lodge , Kaw rd. 6, 04º33.579’N, 52º12.433’W, 977’, MV light, 19-31.VII.2019, Morris & Wappes leg. ( FSCA, formerly RFMC) . Paratype, 1 specimen from FRENCH GUIANA: Montagne de Kaw-Roura , Carrefour de Fourgassier, X.2015, F. Robin leg. ( FRCO) .

Etymology. The new species is dedicated to Roy F. Morris (RFMC).

Remarks. Anisopodus morrisi sp. nov. is slightly similar to A. bellus Martins & Monné, 1974 (see photographs on Bezark 2021a), but differs by the presence of the lateral tubercles of the prothorax (absent in A. bellus ), narrow elytral base (proportionally wider in A. bellus ), and elytra with longitudinal dark macula on basal half (transverse in A. bellus ). It is also similar to A. sparsus Bates, 1863 (see photographs on Bezark 2021a) by the prothoracic shape, but differs by the absence of tow rounded black spots on pronotum (present in A. sparsus ), elytra with longitudinal dark macula on basal half (one transverse black macula on each elytron in A. sparsus ), and oblique black macula on posterior half of the elytra (somewhat arched in A. sparsus ).
