Allopeplus cordifer Zajciw 1961

Allopeplus cordifer Zajciw, 1961 (Figs 71–74) Allopeplus cordifer Zajciw, 1961: 222. Remarks. This species was described based on a single female from Brazil (Amazonas). Currently, it is known from Brazil (Amazonas and Rondônia) (Monné 2024a; Tavakilian & Chevillotte 2024). The specimen examined has some differences when compared with the holotype (see photographs on Bezark (2025) and Monné et al. (2024)). However, we believe that they are just specific variations: antennae distinctly surpassing the base of the abdominal ventrite 3; elytra mostly black without violaceous reflections; elytral punctures on the yellow area not shallower and sparser than in most black areas; apex of the mesoventral process 1.33 times apical width of prosternal process (not considering the apicocentral projection); metaventrite with punctures moderately abundant and not sparser; metaventrite entirely black; and metafemora entirely black. Furthermore, the pronotum has sparse but distinct, both fine and moderately coarse punctures, “com pontos finíssimos esparsos, apenas visíveis [with very fine, sparse punctures, barely visible]” in the holotype; and the lateral tubercles of the prothorax distinctly more acute and projected. The lateral tubercles of the prothorax were not described in the original description, but it is possible to see that they are less projected and not acute apically in the holotype; Zajciw (1961) only commented on the prothorax: “fortemente angulado no segundo 1/3 de cada lado [strongly angled on the second 1/3 of each side].” In the holotype female, the antenna “atingem a borda posterior do 1.º segmento abdominal [reaching the apex of the abdominal ventrite 1],” yellow area of elytra forming wide and transverse band from suture to epipleural margin; black area of elytra has distinct violaceous reflections (“com leve brilho violáceo [with slightly violaceous reflections]”), yellow area of elytra forming inverted cordiform macula not reaching lateral areas, elytral punctures on the yellow area “menos densos e mais rasos [less dense and shallower],” “processo mesosternal duas vêzes mais largo que o prosternal [mesoventral process twice the width of the prosternal process]” (we do not know where the dimensions were measured in the holotype, but at no point is the mesoventral process twice as wide as the prosternal process in the specimen examined), “Metasterno com pontos pequenos, dispersos [metaventrite with small and sparse punctures],” “metasterno no meio e abdomen amarelos [center of metaventrite and abdomen yellow],” and “fêmures posteriors, exclusive o ápice que é prêto, amarelo-avermelhados [metafemora, excluding the black apex, reddish-yellow].” Material examined.

Abstract

Allopeplus cordifer Zajciw, 1961 (Figs 71–74) Allopeplus cordifer Zajciw, 1961: 222. Remarks. This species was described based on a single female from Brazil (Amazonas). Currently, it is known from Brazil (Amazonas and Rondônia) (Monné 2024a; Tavakilian & Chevillotte 2024). The specimen examined has some differences when compared with the holotype (see photographs on Bezark (2025) and Monné et al. (2024)). However, we believe that they are just specific variations: antennae distinctly surpassing the base of the abdominal ventrite 3; elytra mostly black without violaceous reflections; elytral punctures on the yellow area not shallower and sparser than in most black areas; apex of the mesoventral process 1.33 times apical width of prosternal process (not considering the apicocentral projection); metaventrite with punctures moderately abundant and not sparser; metaventrite entirely black; and metafemora entirely black. Furthermore, the pronotum has sparse but distinct, both fine and moderately coarse punctures, “com pontos finíssimos esparsos, apenas visíveis [with very fine, sparse punctures, barely visible]” in the holotype; and the lateral tubercles of the prothorax distinctly more acute and projected. The lateral tubercles of the prothorax were not described in the original description, but it is possible to see that they are less projected and not acute apically in the holotype; Zajciw (1961) only commented on the prothorax: “fortemente angulado no segundo 1/3 de cada lado [strongly angled on the second 1/3 of each side].” In the holotype female, the antenna “atingem a borda posterior do 1.º segmento abdominal [reaching the apex of the abdominal ventrite 1],” yellow area of elytra forming wide and transverse band from suture to epipleural margin; black area of elytra has distinct violaceous reflections (“com leve brilho violáceo [with slightly violaceous reflections]”), yellow area of elytra forming inverted cordiform macula not reaching lateral areas, elytral punctures on the yellow area “menos densos e mais rasos [less dense and shallower],” “processo mesosternal duas vêzes mais largo que o prosternal [mesoventral process twice the width of the prosternal process]” (we do not know where the dimensions were measured in the holotype, but at no point is the mesoventral process twice as wide as the prosternal process in the specimen examined), “Metasterno com pontos pequenos, dispersos [metaventrite with small and sparse punctures],” “metasterno no meio e abdomen amarelos [center of metaventrite and abdomen yellow],” and “fêmures posteriors, exclusive o ápice que é prêto, amarelo-avermelhados [metafemora, excluding the black apex, reddish-yellow].” Material examined.
