Abdomen (Figs 2, 3). Tergite 1 with anterior half dark brown and posterior half light brown, gray tomentose; tergite 1 with a row of whitish marginal setae and macrosetae laterally and with whitish setae dorsally on the posterior margin; tergites 2-3 dark brown, gray tomentose; tergites 2 and 4 with whitish macrosetae laterally and black setae dorsally; tergites 4-8 reddish-brown with whitish marginal setae; sternites reddish-brown with short, sparse, whitish macrosetae; tergite 8 dorsally with black macrosetae apically; sternite 8 with whitish-yellow setae; sternite 8 with tongue-shaped projection on the posterior margin (Figs 9, 11–14).
Terminalia (Figs 9–20). Light brown, except epandrium and gonocoxite dark brown dorsobasally; hypandrium with eight or nine black macrosetae apically and laterally; hypandrium with straight posterior margin, without projection (Figs 9, 11, 12, 14, 15); epandrium with black and yellow setae dorsally, and black macrosetae ventrally at apex; epandrium with a dorsal curvature in lateral view (Figs 9, 12, 20); epandrium with an apical small pointed projection internally (Figs 10, 11, 13, 14, 18, 19); epandrium curving inward apically, forming a subtriangular apical cavity in ventral view (Figs 11, 14, 19); cercus cone-shaped (Figs 13, 18); gonocoxite with apical margin rounded (Figs 9, 11, 12, 14); gonostylus narrow and slender (Figs 11, 12, 14); ejaculatory apodeme long and wide apically (Figs 12, 13).
Holotype condition. Left antenna missing, without the postpedicel and the stylus. Few mystacal macrosetae broken. Part of the abdomen and terminalia in microtube with glycerin. Microtube pinned under the specimen.

Variations. Male paratype with two yellow occipital macrosetae; body length 12. 5 mm and wing length 8 mm.
Etymology. inesperatus from Latin, refers to something unexpected.
Distribution. State of Tocantins, Brazil.
Biology/phenology. The specimens were collected in the district of Taquaruçu, a tourist region of Palmas, capital of Tocantins. It is a mountainous region, with valleys, plains and cliffs with elevations ranging from 34 to 960 m (SEPLAN, 2003). This area has a rich vegetation, with typical cerrado, gallery forest and riparian forest. The climate is semi-humid tropical, with seasonally well-defined rainfall periods, with a hot and dry winter (May to September) and a rainy season (October to April) (MARCUZZO & GOULARTE, 2013). The specimens were found in riparian forests of an Environmental Protection Area called Serra do Lajeado, being captured with a Malaise trap both in the dry and rainy seasons. The data obtained here corroborate the information presented by CAMARGO et al. (2022), in relation to the distribution patterns of the other species of the genus.
Type material. Holotype ♂, BRASIL, TO[CANTINS], Palmas, Taquaruçu, Faz [enda] Encantada, 10°14’41.79”S; 48°7’22.79”W, 15-22.IV.2012, Malaise, Krolow, T. K. & Lima, I. L. H. (INPA) / Holotype Cerozodus inesperatus det. Montanuci, P. S.B, 2021. Paratypes. Same data as holotype except: 26.X-02.XI.2012 (♂ CEUFT / 004816); 03-10. VIII.2012 (♀ INPA); 07-14.IX.2012 (♀ CEUFT / 004819).
Discussion. Cerozodus was recently reviewed by CAMARGO et al. (2022) and currently has four valid species. Cerozodus inesperatus sp. nov. runs to step 2 of the key by CAMARGO et al. (2022), from this point it can be easily distinguished from the other species by presenting the hypandrium with a straight margin, without projection (Fig. 15), and its conspicuous tongue-shaped projection in this species is found on the sternite 8 (Figs 12, 17) and not on the hypandrium as in other species of the genus.
