Triatoma gomeznunezi Martínez, Carcavallo & Juberg, 1994

( Fig. 4C )

Triatoma gomeznunezi Martínez, Carcavallo & Juberg, 1994: 15 ; Carcavallo et al., 2000: 70; Galvão et al., 2003: 10; Schofield & Galvão, 2009: 92; Monteiro et al., 2018: 284.

Diagnosis. Male body length 21.0 mm. Regular size eyes in dorsal view, synthlipsis wider than eye, and postocular region subequal to eye length. Clypeus, genae and jugae covered with conspicuous long pilosity. Antenniferous tubercle laterally covered with long setae and dorsally glabrous. Neck polished and entirely black. Posterior lobe of pronotum brownish, distinctly lighter than anterior lobe. Humeral angles rounded. Overall color of corium dark brown, with basal and subapical yellowish spots. Conexivum with segments black on anterior half and yellow on posterior half, extending to connexival suture.

Specimens examined. None.

Distribution. Mexico: Oaxaca ( Galvão et al. 2003).

Comments. There are no molecular studies available for this species. Martínez (1994) mentioned that T. gomeznunezi is similar to T. brailovsky in several morphological characters, except measures of head structures and shape of the scutella. Carcavalho et al. (2000) proposed that T. gomeznunezi is close to T. brailovsky , T. dimidiata , and T. hegneri , based on morphological similarities between these species without details. This statement was followed by Schofield & Galvão (2009), Georgieva et al. (2017) and Monteiro et al. (2018), who proposed that T. gomeznunezi is related to several species of the T. phyllosoma species group, without details of their decision. Here, we assume that T. gomeznunezi is related to the T. phyllosoma species group because it is morphologically close to T. brailovsky . This latter species is the sister taxon of the remaining species of the T. phyllosoma species group according to molecular data ( Espinoza et al. 2013).
