Tupiniquim confusa Linzmeier, Oliveira & Konstantinov, new species

(Figs 14–22)

Diagnosis. Tupiniquim confusa can easily be differentiated from its congener (in parentheses) by the following features: setiferous pores in a small cluster of three on each side of vertex near eyes (four setiferous pores organized in two longitudinal lines); posterior margin of pronotum without depressions (two small depression on posterior margin of pronotum); pronotal surface finely textured (pronotal surface almost smooth, with fine punctures); elytra with punctures confusedly organized (elytra with punctures barely organized in rows); median lobe of aedeagus at apex bent ventrally in lateral view (median lobe of aedeagus straight).

Description. Body 1.73–2.05 mm long and 1.08–1.13 mm wide. Color entirely yellow or brown; in brown specimens pronotum and head sometimes darker and antennae and legs lighter. Frons and vertex forming about 135º angle, in lateral view. Supraorbital pore almost indistinguishable from two or three other pores closely placed in cluster (Fig. 16). Ridge from inner margin of antennal socket to eye not inclined towards insertion of antenna. Pronotum rectangular, width 1.5 times length. Surface of pronotum microreticulate. Elytra punctured, with punctures confused (Fig. 14). Median lobe simple, tubular, in ventral view lateral expansion slightly longer and farther from apex, apex with long, wide denticle; in lateral view abruptly curved basally, apex bent ventrally, straightening further apically (Fig. 21).

Spermatheca with receptacle having external side nearly straight and internal side strongly convex; pump with longitudinal part much shorter than transverse part (Fig. 22). Tignum with posterior sclerotization about half as wide as tignum entire length (Figs 18, 20).

Type material. Holotype:male (DZUP). Brazil: Bahia; W of Camacan, 900m; Serra Bonita N. R.; 16-18.XI.2012; S. & Sv. Kurbatov, legs . / Holotype, Tupiniquim confusa Linzmeier, Oliveira & Konstantinov, sp. nov. 2021 [red label].

Paratypes (3): 2 males, 1 female; USNM: same data label as holotype .

Etymology. The specific epithet is a Latin adjective referring to one of the distinctive characteristics of this species, punctures on elytra confusedly distributed.
