Barolineocerus ornatus Freytag, 2008 (Figs. 1T–W, 4G–I, 16A–M) Barolineocerus ornatus Freytag, 2008: 58, figures 29–31. Type locality: Saül, French Guiana. Diagnosis (based on material collected in Brazil). Pronotal macula almost extends to hind margin of pronotum (Fig. 1T, 4G). Claval macula extends distinctly beyond scutellum apex (Fig. 1T, 4G). Abdominal sternite II apodeme almost extending to posterior margin of sternite III (Fig. 16B). Pygofer posterior margin with ventral process; with long median process, mostly straight, apex multifurcate (Figs. 16C–E). Valve with anterior and posterior margins straight (Fig. 16F). Subgenital plate without dorsal process; apex rounded (Figs. 16G–H). Aedeagus with dorsal median process; without dorsal subapical ridge; with ventral transverse ridge at apical fourth (Figs. 16L–M). Anal tube, laterobasal process with base sinuous at anterior margin, apex distinctly pointed (Figs. 16C, E). Measurements (mm).

Holotype condition. Body covered with sparse Lepidopteran scales. Remarks. Freytag (2008) provided illustrations of the male genital capsule (lateral view), subgenital plate (ventral view), connective, style and aedeagus (ventral view) of B. ornatus. However, based on study of the holotype, his illustrations of the median process of the pygofer and anal tube are inaccurate. In the holotype, the pygofer process is long and somewhat straight, except at the apex, where it bends ventrally; also the apex is not bifurcate, but multifurcate, somewhat asymmetrically, with the right process ending in four tooth-like processes, while the left one has three (similar to what is illustrated in Figs. 16C–E). Specimens vary in the hind tibia AD row with 5–6 cucullate setae and PD row with 12–15 cucullate setae. Barolineocerus ornatus shares affinities with B. chiasmus, B. furcatus, B. ornatus, B. dercyae sp. nov., B. chicomendesi sp. nov., and B. digitatus sp. nov. as mentioned earlier. It is particularly similar to B. chiasmus, B. chicomendesi sp. nov., and B. digitatus sp. nov., differing in having the pygofer processes multifurcate (Figs. 16C–E).
