Type material. HOLOTYPE. Greece, ♂, pinned, in NBCN. Original label: “Griekenland, Prov. Pindos gebergte, Plaats Kalliroi, 19.v.1988, leg. G. den Hollander ” (det. as Cheilosia longula by G. den Hollander, 1984).
Diagnosis. Species related to Cheilosia paralobi, but differs in the following characters: face partly microtrichose on genae, along paraface and between antennae and facial tubercle in C. candida sp. n. (Fig. 1A), while in C. paralobi entire face microtrichose, except facial tubercle (Fig. 1B); basoflagellomere of male partly reddish in C. candida sp. n. (Fig. 1D), while in C. paralobi almost completely black (Fig. 1E) (in some specimens inner side basally with paler macula); frons covered with intermixed black and yellow pile in C. candida sp. n., while in C. paralobi only with yellow pile. Male genitalia: surstylus shorter in C. candida sp. n., about three times longer than broad basally (Fig. 4B), while in C. paralobi very narrow apically and elongated, more than five times longer than broad basally (Fig. 5E).
Description. MALE. Head (Figs 1A, 1 C–D). Antennae dark, brown-reddish; basoflagellomere dark-brown with reddish macula basoventrally, ellipsoidal, about 1.3 times as long as broad, and 3.5 longer than pedicel; arista 1.5 times longer than antennae, covered with short pile (Fig. 1D); face wide, 1/2 of the width of head anteriorly, covered with long, pale-yellow pile along paraface in upper 1/3 (Fig. 1A); facial tubercle rounded; genae, face between antennae and facial tubercle, and along paraface covered with grey microtrichia; frons convex, shiny, covered with mixed yellow and black pile; vertex convex and shiny; ocellar triangle equilateral, covered with mixed yellow and black pile; eyes bare; eye contiguity shorter than length of frons (Fig. 1C); occiput narrow, with white-grey microtrichia, covered with yellow pile, with additional black pile dorsally along eye margin. Thorax (Fig. 3). Scutum black, with dark-golden color, laterally slightly microtrichose, covered with long yellow pile, except wing bases covered with black pile and few black ones in notopleural area; central disk shiny, with fine punctuation; scutellum covered with yellow pile (Fig. 3A, C); metathoracic pleuron slightly microtrichose, covered with pale-yellow pile and wavy at apical end; wing membrane brownish medially, with brown veins, completely microtrichose; vein M1 meeting vein R4+5 at acute angle; halters light to dark-brown; calypteres yellowish-gray; all legs dark-brown/black, except light-brown apex of femora, basal 1/3 and apical end of tibiae, and ventral surface of tarsi; legs grey microtrichose and with mixed yellow and black pile, although yellow ones dominate (Fig. 3B). Abdomen (Fig. 3C). Terga dull, covered with mostly yellow pile, except few black ones on pregenital segment; sterna grey microtrichose, covered with yellow pile, except few black ones on sternum 4. Male genitalia (Fig. 4). Surstylus about three times longer than broad basally, with central bulge from lateral view (Fig. 4B); dorsal lobus of gonostylus sickle-shaped, with spine-like dorsal prolongation (marked with arrow on Fig. 4A).
FEMALE. Unknown.
Etymology. The new species is named according to the Latin adjective ‘ candida ’ meaning bright (not dark), indicating yellow color of body pile and reddish antennae.
Distribution. Known only from Greece, from a locality on Pindos Mountains (Fig. 6).
