Diagnosis. Total length, female 22.9 mm (n = 6), male 20.1 mm (n = 5). General coloration red or dark red (Figs 7B, D); tubercle of the anterior pronotal lobe straight, constricted near the middle and markedly globose apically (Fig. 7E); elevation of the carina of the posterior pronotal lobe narrow (Fig. 7E); scutellum apically rounded (Fig. 7F); connexivum nearly straight, abdominal mediotergites and most of dorsal laterotergites on segments 2–4 black, segments 5–7 black with a bright yellow broad band increasing in size toward the posterior segments (Figs 7B, D), also visible on the ventral laterotergites, but less bright (Figs 7A, C); membrane usually translucent, sometimes translucent yellow (some Amazon specimens).
Variation. The specimens examined show some degree of variation in terms of coloration, such as in the membrane, which is hyaline in most of the examined specimens, including the lectotype (Figs 7B, D; 30), but golden in the specimens examined from Leticia (Amazonas). Specimens of localities above 1000 m have an overall darker coloration. Moreover, the pattern on the dorsal laterotergites of segments 5–7 is also slightly variable with regard of the extension of the dark area.
Differential diagnosis. Among those species with connexival segments not strongly lobed, Montina confusa is similar to M. testacea because of the overall reddish coloration (Fig. 7), although M. testacea has an almost uniform coloration on the ventral laterotergites (Figs 21A, C), unlike M. confusa which has a strongly contrasting black and yellow pattern on the ventral laterotergites (Figs 7A, C). It might also be confused with M. distincta because of the contrasting pale band against a dark area on the ventral laterotergites (Figs 9A, C), although M. distincta has an overall pale brown coloration (Figs 9B, D). Additionally, M. confusa has the anterior pronotal lobe tubercles apically globose and with a pre-apical constriction (Fig. 7E), the scutellum with a rounded apex (Fig. 7F), the elevation of the carina of the posterior pronotal lobe narrow and tubercle-like (Fig. 7E), and the margin of the connexivum with an acute tubercle on the posterior half of each of segments 2 and 3 in females and also on segments 4 and 5 in males (Figs 7A, C). Both M. distincta and M. testacea have subconical tubercles on the anterior pronotal lobe which are not preapically constricted, the elevation of the carina of the posterior pronotal lobe is truncated or rounded (Figs 9E, F; 21E), and the scutellum is apically acute.
Biology. In Colombia, Montina has been reported as a predator of insect pests of agricultural crops such as corn and others (AYALA et al. 2013, LEṒN MARTÍNEZ & GUEVARA AGUDELO 2006), although the species involved have never been identified. Nevertheless, specimen images in these reports seem to correspond to M. confusa (e.g., GUEVARA & JIMḖNEZ 2018). Even some of the Amazonian specimens were collected in “chagras”, which are indigenous cultivation plots (ESCOBAR et al. 2005). Therefore, given that M. confusa can be found in agricultural crops in Colombia this species should be studied as a potential predatory agent against pest species.
Distribution. Brazil, Peru (MALDONADO 1990; STÂL 1859, 1868), and Colombia (Amazonas, Caldas, Caquetá, Casanare, Cundinamarca, Meta, Vichada), with altitudinal records between 100 and 2,000 m (Fig. 40).
Remark on types. STÂL (1859) described M. confusa based on females from “Brasilia?” deposited at ZMHB (“Mus. Berol.”). We have located two females, one at ZMHB and another at NHRS that might be considered syntypes. We are designating the specimen from ZMHB as the lectotype (Fig. 30) because it is found in the same collection as when originally described, and the locality (Para) is congruent with “Brasilia”.
