Figs 15–19, 22, 26, 28
Type material. HOLOTYPE: male, deposited at CNC, and labelled: “ COSTA RICA / B. Carrillo N.P. / 84°07’W - 10°10’N / 10.IV.85; 500 m. / leg. H. Goulet-L. Masner”.
PARATYPE: 1 ♂, same label data as holotype. Coll. CNC.
Comparative diagnosis. Body length: male 8.5 mm. This species is readily distinguished from the other four species by the very long basoflagellomere (Fig. 17), which is more than three times longer than the scape. It also differs from all other species by the entirely black tergite 3 (Figs 19, 26).
Description (holotype). MALE. Body length: 8.5 mm. Head (Figs 17, 18). Dichoptic. Face occupying about 1/3 of total head width in frontal view, pale yellow with brownish black median vitta occupying 1/2 of facial width, yellow pilose medially, silvery white pilose laterally, with some black pile on anterior oral margin, eye margins slightly converging at level of frons, with smallest distance approximately equal to four times width of antennal fossa. Gena black. Oral margin laterally produced, black. Antennal fossa about as wide as high. Frons shining black, except dark yellow anterolaterally, black pilose, except golden yellow pilose on yellow areas. Vertex convexly produced, shining blackish brown, sparsely black pilose. Ocellar triangle not elevated, anterior angle about 100°. Occiput narrow ventrally (hardly visible in lateral view), widened dorsally, black, golden yellow pilose on dorsal 1/3, white pilose on ventral 1/3, black pilose in between. Eye bare. Antenna black, except scape brown on basal 1/2, ratio of scape: basoflagellomere approximately as 1:3.5 (pedicel very short), basoflagellomere longer than height of head, elongated with rounded apex, arista slender, about 1/2 the length of the basoflagellomere, pale brown.
Thorax. Mesoscutum black with faint bronze hue, black pilose, except for an anterior, a sutural and a prescutellar fasciae of golden yellow pile (the anterior and sutural fascia are medially interrupted). Postpronotum brown, yellow pilose. Postalar callus brown, black pilose. Scutellum with two apical calcars with 1/5 of the length of the scutellum, yellowish brown with faint metallic hues. Pleurae brown. Anepisternum with anterior and posterior parts separated by clear sulcus, anterior part golden yellow pilose, posterior part white pilose, except posterodorsal margin black pilose, with bare area in between. Anterior anepimeron black pilose dorsally, white pilose ventrally. Katepisternum white pilose dorsally, bare ventrally. Katatergum with long brownish microtrichia. Anatergum short whitish microtrichose. Other pleurites bare. Calypter greyish, halter yellowish white. Wing: Hyaline, slightly brownish on anterior half. Microtrichose, except bare on narrow strip at base of cell r1, posterobasal 1/2 of cell br, posterobasal 2/3 of cell bm, and anterobasal 1/3 of cell cup. Legs: Yellowish brown, except femora darker brown and near blackish dorsally. Femora black pilose, except hind femur silvery white pilose anteriorly on basal half. Front tibia black pilose except for strip of golden yellow pile posterolaterally. Mid tibia silvery white pilose, except black pilose posteriorly and around apical 1/4. Hind tibia silvery white pilose anteriorly and laterally on basal 2/3, black pilose otherwise. Tarsi black pilose dorsally, golden yellow pilose ventrally. Abdomen (Fig. 19). Tergite 1 blackish brown, yellow pilose medially, black pilose laterally. Tergite 2 pale yellow with a triangular posteriomedian blackish brown macula of approximately 1/3 of width of tergite, black pilose, except silvery white pilose in anterolateral corners and anteromedially. Tergite 3 blackish brown, black pilose, except silvery white pilose along lateral margins. Tergite 4 blackish brown, black pilose, except silvery white pilose laterally and with pair of submedian vittae of golden pile which reach from the anterior to the posterior margin. Sternite 1 blackish brown, bare. Sternite 2 yellowish white, black pilose. Sternite 3 yellowish white anteriorly, blackish brown posteriorly, black and white pilose. Sternite 4 blackish brown, black and white pilose. Genitalia as in Fig. 22.
FEMALE. Unknown.
Etymology. The specific epithet ‘ sensibilis ’, a Latin adjective for sensitive, alludes to the long antennae of the species.
Distribution. NEOTROPICAL—Costa Rica (Fig. 28).
