Paraleia tonnoiri , sp. n.

( Figs. 9 , 20 )

Diagnosis. Two ocelli. Wings without clear markings. Gonocoxite distal extension with an irregular row of short spines on distal two thirds at inner surface, two regular, parallel, longitudinal rows of short spines near apex, short spines distributed around the apex, and a long subapical spine. Gonostyle long, pointed at apex, with a longitudinal row of short spines at distal fourth, two short rows of spines and a long, subapical spine.

Material examined. Holotype 3, COLOMBIA, State of Magdalena, PNN Santa Marta, San Lorenzo, 10°48’N 73°39’W, 2,500 m, 15–30.i.2001, M1186 (J. Cantillo Leg.) (IAvH).

Description. Male. Head. Vertex brown, with scattered, whitish, longer bristles. Two ocelli close to, but not touching eye margin, mid ocellus absent. Frons and clypeus light brown, with scattered setulae; labella yellow, maxillary palpus whitish yellow, five palpomeres, last palpomere almost twice length of penultimate, first two palpomeres short. Scape and pedicel of equal length, yellow, first flagellomere yellow at basal half, light brown distally, second and third flagellomeres light brown, with basal fourth lighter, distal flagellomeres light brown (flagellomeres 9–14 missing). Thorax. Pronotum yellow, with five strong bristles, three anterior and two mesal. Scutum light brown, two narrow yellow bands beginning on anterior corners and joining in the median region of scutum. Scutellum yellow, four scutellar bristles. Mediotergite and lateral sclerites light brown, bare. Pleural membranae yellow. Haltere whitish, setose. Legs yellow. Tibial spurs 1:2:2, spurs almost twice width of tibia apex. Mid and hind tibiae with long and strong setae. Wing ( Fig. 9 ). Width, 2.4 mm. Membrane without macrotrichia, yellowish, no clear markings. Sc complete, ending in C; sc-r absent; CuA slightly curved midway to apex; A1 weakly sclerotized, absent on distal third. M4, second sector of CuA and A1 setose. Abdomen. Abdomen pubescent. Tergite 1 light brown, tergites 2–6 light brown with a distal yellow band, tergite 7 yellow. Sternites yellow, sternites 6 and 7 with brownish spots. Terminalia ( Fig. 20 ). Terminalia yellow, gonostyle and gonocoxite with brownish distal margin. Gonocoxite distal extension with an irregular row of short spines on distal two thirds at inner surface, two regular, parallel, rows of short spines near apex, and additional short spines around the apex, besides a long subapical spine. Gonostyle long, pointed apically, with a longitudinal row of short spines at distal fourth on inner surface, two short transversal rows of spines, and a long, subapical spine; aedeagus thin, entirely bifid; parameres well developed, more sclerotized at apex, involving aedeagus; cercus not visualized; tergite 9 weakly sclerotized, straight at distal margin.

Female. Unknown.

Etymology. The specific epithet is formed after the Belgian entomologist André Léon Tonnoir (1885–1940), who described a large number of species and genera of Mycetophilidae from Australia and New Zealand region, including the first known species of Paraleia .

Comments. One of the wings of the only specimen known is entirely missing and the other wing has the distal part missing. The aedeagus is bifid from its base to the apex, the presence of only two ocelli and the regular rows of short spines at the apex of gonostyle clearly approximate this species to P. fumosa sp. n. However the gonocoxite distal extension and wing maculation are very particular in each of these species. The gonocoxites of P. tonnoiri sp. n. show an irregular longitudinal row of short spines at their inner surface and one apical spine longer and curved ( Fig. 20 ); the wing membrane seems do not have maculation ( Fig. 9 ). In P. f u m o s a sp. n. the gonocoxites have a row of short spines along distal margin, with one very long; an additional transverse row of short spines ventrally ( Fig. 16 ); the wing membrane shows maculae brown close to the wing apex and just posterior to A1 ( Figs. 5, 6 ).
