(Figs. 14, 65, 66, 77, 120)
Diagnosis. Separable from other members of the mexicanus subgroup by the following combination of characters: Prementum brown. Leg joints narrowly orange. Mid tibia with a row of anterodorsal bristles. Mesoscutum shallowly sculptured. Tarsi with distal three tarsomeres brown.
Description. Head orange, occiput blackish medially, prementum brown, maxillary palp yellow. Mostly covered with microtomentum, frons with microtomentum medially reaching from postocellar bristles anteriorly through ocellar triangle to anterior margin of frons, microtomentum on orbital plates reaching bases of interfrontal setae, face with patch of microtomentum below lunule and antenna, occiput with shiny patches lateral to foramen. Ocellar bristles at level of anterior margin of median ocellus. Subvibrissal bristle about 0.3X length of vibrissa, anterior genal bristle about 0.5X length of vibrissa.
Thorax black, mostly covered with microtomentum. Proepisternum shiny, anepisternum with ventromedial shiny spot covering about two-thirds height and two-thirds length of sclerite, katepisternum with a shiny spot behind fore coxa, meron shiny. Mesoscutum shallowly sculptured (Fig. 14). Halter white, brownish below knob.
Legs black, trochanters and joints orange, tarsi with 2 basal tarsomeres yellow, 3 distal tarsomeres brown. Mid tibia with row of anterodorsal, 1 anteroventral, 1 posteroventral, and 5 subapical bristles. Hind tibia with 1 thin anteroventral, 1 ventroapical bristle.
Wing brown, faint spots around crossveins r-m and dm-cu, very faint paler spots on vein R4+5 distal to crossvein r-m.
Abdominal tergites 1–4 heavily sclerotized, black, covered with microtomentum, syntergite 1+2 with a semicircular weakly sclerotized patch anteriorly. Tergite 5 weakly sclerotized, anterolateral corners heavily sclerotized. Sternites weakly sclerotized.
Male postabdomen: Sternite 5 more or less parallel-sided, slightly longer than wide, posterior margin with a shallow notch and interrupted row of setae, anterior apodeme broad, slightly longer than external portion, without keel (Fig. 66). Surstylus paddle-shaped. Hypandrial arms with ventral tab-like structures. Pregonite small, discrete. Postgonite narrowed above lobes, lobes widely separated, anterior lobe broad, rounded, posterior lobe pointed. Basiphallus with long epiphallus, short, broad, transparent preepiphallus. Distiphallus with spinose dorsal tube strongly curved near base, distal portion flattened, extending just beyond ventral portion of distiphallus (Fig. 65).
Female postabdomen: Tergites 6–7 with anterior and lateral margins heavily sclerotized, center and posterior margin not sclerotized. Tergite 8 covered with microtomentum, except anterior margin. Epiproct without anterior arms, mostly covered with microtomentum except anterior corners, with 2 setae. Cerci broad. Sternites 6–7 with margins heavily sclerotized, center not sclerotized. Sclerites of sternite 8 broadest posteriorly, posterior half covered with microtomentum. Hypoproct lozenge-shaped, covered with microtomentum. Spermathecae about 1.5X longer than wide, sculptured with longitudinal, wavy striations, apex deeply invaginated, base shallowly invaginated, sclerotized duct about as long as bulb with distinct angular projections (Fig. 77).
Type material. Holotype ♂: GUATEMALA: Zacapa: San Lorenzo, 7 km N, 2000 m, dung, 10–17 Jun 1993, B.D. Gill, debu01040175 (DEBU). Paratypes: same data as holotype (28 ♂, 46 ♀, DEBU); San Lorenzo, 5 mi N, FIT, 4–18 Jul 1986, J.M. Campbell (1 ♀, DEBU); El Progreso: Cerro Pinalón, 2550 m, cloud forest, Malaise trap, 29 Apr–5 May 2009, [no collector] (1 ♀, UVGC).
Distribution. Eastern Guatemala (Fig. 120).
Etymology. The species name is an arbitrary combination of letters derived from the province where most of the type series was collected.
