Type material. Holotype male from ECUADOR, Napo: Cosanga , 2100 m, adult on wood at night, 25.XI.2022, J. Vlasak leg. ( MZSP) . Paratypes (same data as holotype) – 8 males ( JVCO), 1 male ( DHCO), 1 female ( MSZP), 3 females ( JVCO), 1 female ( DHCO).

Etymology. The specific epithet “micromaculatus,” from Latin micro (small) and macula (spot), refers to the small, yellow pubescent spots on the elytra.

Remarks. Anisopodus micromaculatus new species is similar to A. cochabambaensis Schmid, 2016 , but differs as follows: distance between upper eye lobes shorter than 1.5 times the maximum diameter of the scape; lateral tubercles of the prothorax not located near posterolateral angles; sides of grayish-white pubescent macula of the elytra not inclined forward on anterior region; elytra with small, both grayish-white and yellow pubescent spots; laterocentral dark area of the elytra larger, reaching posterior third; outer apical spine of the elytra distinctly longer than pedicel; and meso- and metafemoral club slender, about as wide as apical width of the elytron. In males of A. cochabambaensis , the distance between upper eye lobes is equal to 1.5 times the maximum diameter of the scape, lateral tubercles of the prothorax located near posterolateral angles, sides of grayish-white pubescent macula of the elytra directed forward on anterior region, elytra without grayish-white or yellow pubescent spots, laterocentral dark area of the elytra smaller, not reaching posterior third, outer apical spine of the elytra about as long as pedicel, and meso- and metafemoral club wider, distinctly wider than the apical width of the elytron.
