Brachyopa minima Vujić & Pérez-Bañón sp. nov.

Diagnosis. Small species (6–7 mm). Scutum ( Figs 3 View FIGURE 3 A, B) covered with grey microtrichia except: pair of small bare spots posteromedian to the postpronotum; a pair of large bare spots anterior to transverse suture and median to notopleural sulcus; spots at the median ends of transverse sulcus covered by brown microtrichia; postalar callus with a bare spot; two stripes bare of microtrichia on posterior part of scutum located laterally. Male terminalia on Figs 4–5 View FIGURE 4 View FIGURE 5 ; surstylus with well-developed ventral lobe ( Figs 4 View FIGURE 4 A, 5 A); dorsal and ventral margins of surstylus straight ( Figs 4 View FIGURE 4 A, 5 A); hypandrium wide with complex apical appendages ( Figs 5 View FIGURE 5 C, D).

Etymology. The specific epithet minima means "smallest" and refers to the size of the species, which is smaller than most other members of the genus.

Description. MALE. Body length 6–7 mm, wing length 7 mm. Head ( Figs 1 View FIGURE 1 A, C; 2 A–C). Length to height ratio of head 0.97. Face moderately protruding ( Fig. 1 View FIGURE 1 C). Length to width ratio of clypeus 1.4. Length to width ratio of subcranial cavity 1.6; 1.7 times as wide as the shortest distance from the eye to the subcranial cavity. Orbital strip ( Figs 2 View FIGURE 2 A, B) shallow, in narrower part as wide as the maximum width of arista. Pile on all parts of the head capsule pale, except black pile on upper part of occiput near eye margin. Frons and vertex ( Fig. 1 View FIGURE 1 A) microtrichose, only narrow area above lunule and around ocelli bare. Length of eye contiguity about 0.4 times the length of frons, shorter than ocellar triangle. Distance between posterior ocellus and eye margin about equal to two ommatidium diameters. Hypostomal bridge grey-reddish, paler anteriorly, entirely microtrichose, except bare hypostomal sulcus. Face ( Figs 2 View FIGURE 2 A, B) microtrichose except for a fascia from the tentorial sulcus to the mouth. Length to height ratio of postpedicellus 1–1.15, with small sensory pit ( Fig. 2 View FIGURE 2 C). Arista ( Fig. 2 View FIGURE 2 C) with very short pile (shorter than 1 / 3 the maximum width of arista), with orange base and darkened toward apex. Thorax. Black except for the postalar callus, which is partly reddish, and the metasternum and probasisternum which are more or less reddish. Scutum ( Figs 3 View FIGURE 3 A, B) entirely densely covered in grey microtrichia except for a pair of bare maculae posteromedian to the postpronotum; a pair of bare maculae anterior to transverse suture and median to notopleural sulcus (maculae at the median ends of transverse sulcus covered by brown microtrichia); postalar callus with a bare spot; two stripes bare of microtrichia on posterior part of scutum located laterally. Notopleural sulcus impressed. Thoracic bristles not well differentiated from the pile. Postpronotum pale haired, with few black pile mixed in.

Scutum predominantly black haired except for its anterior margin and the notopleuron, which are pale haired, a few pale pile that are present at the supra-alar area, and the postalar callus that is pale haired. Scutellum rather trapezoidal, without a distinct depression, mainly orange, only slightly darkened anteriorly and anterolaterally, with two pairs of strong black marginal bristles; predominantly pale haired mixed with black pile medially; only anterior half covered with microtrichia ( Fig. 2 View FIGURE 2 D). Mediotergite microtrichose below subscutellum, except at posterior margin. Proepimeron and anterior flat part of mesanepisternum bare. Posterior surface of mid coxa without pile. Legs orange, 5 th tarsomere of all legs black, tarsomeres 1–4 of metatarsus darkened dorsally. Legs pale pilose except for the usual black bristles on hind femur ventrally, apex of mesotibia ventrally with strong black bristles, the ventral surface of mesotarsus with black bristles. Haltere yellow with light yellow capitulum. Wing without dark spots. Abdomen. Tergites and sternites orange, except first tergite and first sternite with dark grey area laterally, pile all pale. First tergite entirely microtrichose, second tergite extensively covered with microtrichia except for the posterior margin narrowly and large area at the posterolateral corners, which are bare. Sternites entirely densely microtrichose. Male terminalia on Figs 4–5 View FIGURE 4 View FIGURE 5 . FEMALE. Differs from the male in the following characters: length to width ratio of frons 1.46–1.54. Frons ( Fig. 1 View FIGURE 1 B) entirely microtrichose except shiny anterior area above antennae, with small central microtrichose spot (this spot lacking in B. quadrimaculosa ). A narrow pollinose stripe running from the dusted area of the frons downward along the eye margin, widening beside the lunule and merging with the wide pollinose cross band that covers the dorsal part of face (face less covered by microtrichia than in male, without bare spot below each antenna, contrary to B. quadrimaculosa ) ( Fig. 1 View FIGURE 1 B). Length to height ratio of postpedicellus 1.14–1.15, a little larger than in male, with a minute sensory pit. Tibiae and tarsi darker than in male.
