Diagnosis. See diagnosis of C. irazuana for comparison of characters. Three postsutural intra-alar setae, the one closest to the suture (Fig. 50, arrow) strong; lower calypter usually with rim and setal fringe whitish, especially on proximal end (rarely tan in color), also whitish in C. lopesi, but geographical ranges do not overlap; genal dilation wholly black to dark brown. Male frons narrow, 0.035 head width; surstylus broad in lateral view (Fig. 14), cerci often Y-shaped in posterior view (Fig. 15, Y-shape not prominent in this photo). T5 of female abdomen lacks incision. Known only from Costa Rica, El Salvador, and Mexico, likely found in other Central American countries at higher elevations.
Description. Parafacial, fronto-orbital plate, genal dilation, and frontal vitta all black to dark brown or rarely reddish brown when viewed from below; from above, parafacial, fronto-orbital plate and genal dilation with silvery microtomentum; upper parafacial and lower fronto-orbital plate each with a changeable spot; pedicel brown but apical rim usually orange; basal portion of first flagellomere orange, the remainder brown to orange-brown; occiput below postocular setae with 3–4 irregular rows of dark setae, the remainder of occiput with long whitish setae; ocellar triangle small, anterior ocellus and posterior ocelli about equal in size; facial ridge with row of strong supravibrissal setae ascending about 80% of way to antennal base. Thorax normally with three prominent postsutural intra-alar setae, the anteriormost seta sometimes reduced, rarely absent. Anterior spiracle dull orange to light brown, posterior spiracle sooty black. Upper calypter brown in center, lighter near edges, rim and fringe brown; lower calypter all brown, rim and fringe usually pale, more whitish at distal end (Fig. 3); about 10% of specimens examined with rim and fringe tan in color. Normal body length of males 9–10mm, females 9–12mm.
Male. Frons narrow 0.031 (0.030–0.035/5) head width at narrowest; 0.42 (0.38–0.46/5) of first flagellomere; parafacial at narrowest almost 3x frons width, 2.7 (2.5–3.0/5); 1.18 (1.0–1.36/5) of first flagellomere; gena to eye ratio 0.42 (0.40–0.42/5). Two changeable spots on parafacial, one at upper end, one about midway. Surstylus broad and digitate in lateral view (Fig. 14); in posterior view, base of cerci broad, tapering to narrower distally, the distal third of cerci often meeting in a y-shape; cerci and surstyli about equal length (Figs. 15). Phallus with epiphallus angling downward more sharply than in other species (Fig. 22, 23). Hypandrium, pre- and postgonite, ejaculatory sclerite and sternites as in Figs. 33–35, 39.
Female. Frons 0.33 (0.31–0.34/5) of head width at narrowest; 3.36 (2.9–4.2/5) of first flagellomere; parafacial at narrowest 0.39 (0.36–42/5) of frons; 1.32 (1.1–1.6/5) of first flagellomere; gena to eye ratio 0.57 (0.54–58/5). Two changeable spots on parafacial like male, one midway on fronto-orbital plate not present in males. Ovipositor and spermathecae as in Figs. 43, 47; posterior end of ST7 with a narrow neck-like constriction similar to C. vicina.

Other material examined. Some specimens were discolored, distorted or damaged and were not treated as paratypes; these included 21 specimens (3 males and 18 females) from Costa Rica (INBIO).
Distribution. Costa Rica, El Salvador, and Mexico, and likely in mountainous areas throughout Central America and southern Mexico (Fig. 1). This species occurs in some of the same areas where C. irazuana is found; see discussion under that species. Most specimens were collected from 2000–3300m. Based on numerous Calliphora that have been collected in Costa Rica and deposited at INBIO, it is less common than C. irazuana.
Discussion. This species is normally easily separated from C. irazuana because of its black genal groove and parafacial in addition to the extra postsutural intra-alar. However, a few specimens may have the extra seta reduced or rarely absent. In one specimen the head had an orange genal groove and lower parafacial, but pale setae on the occiput and thorax with a distinct third postsutural intra-alar. It is possible this reflects hybridization. Male genitalia readily separate this species from C. irazuana.
Etymology. The species name was chosen due to the presence of a pronounced third postsutural intra-alar seta, a condition unique to this species of Calliphora in the Neotropical Region.
