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 ). FIGURE 2. Gonostylus of male genitalia, lateral view. A Cheilosia latifacies , B Cheilosia hypena , C Cheilosia cumanica . govl—ventral lobus of gonostylus. Scale bar, 0.1 mm. 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 ).
