Triatoma indictiva Neiva, 1912: 22 ; Pinto, 1931: 66; Lent & Wygodzinsky, 1979: 244; Carcavallo et al., 2000: 28; Galvão et al., 2003: 10; Schofield & Galvão, 2009: 92; Monteiro et al., 2018: 284.

Triatoma sanguisuga dimidiata Usinger, 1944: 68 .

Triatoma sanguisuga occidentalis Usinger, 1944: 69 .

Diagnosis. Male body length 18.0– 20.5 mm. Female body length 18.5–22.0 mm. Postocular region distinctly rounded in dorsal view. Neck with 1+1 lateral reddish or yellow spots. Pronotum uniformly piceous or black. Humeral angles rounded. Hemelytra dark brown or piceous, with lighter markings on corium basally and subapically, as well as on clavus. Fore femora stout, about six times as long as wide. Fore and mid tibiae of male with small spongy fossula, absent in female. Overall color of connexival segments piceous to black, with reddish marking extending on posterior suture, very narrow about sixth or seventh of each connexival segment.

Specimens examined. None.

Distribution. Mexico: Chihuahua and Sinaloa; and USA: Arizona, New Mexico, and Texas ( Galvão et al. 2003; Bern et al. 2011).

Comments. This species was related to T. lecticularia and T. sanguisuga ( Lent & Wygodzinsky 1979; Schofield & Galvão 2009). Besides, T. indictiva might be morphologically closer to T. sanguisuga than to T. lecticularia because it was considered a subspecies of T. sanguisuga early ( Usinger 1944).According to ultraconserved elements of molecular data, T. indictiva belongs to the T. phyllosoma species group ( Kieran et al. 2021).
