Diagnosis. Cnodalomyia catarinensis sp. nov. can be easily distinguished from C. obtusa by the entirely yellow mystax and the scutum, which is light brown with dark brown lateral stripes divided into three parts that are not fused. The distiphallus is as long as the gonostylus in C. catarinensis sp. nov. while it is three times longer in C. obtusa ; and the presence of a sharpened beak-like apex on the gonostylus, which is rounded in C. obtusa .

Description. Body length: 10.7–19.3 mm. Wing length: 9.1– 3.4 mm.

Ground color: light brown.

Male. Head: face yellowish brown, golden pollinose; front light brown, golden pollinose, with dark brown and yellow macrosetae; proboscis dark brown, two thirds head height, strong with short basal projection, labella with yellow setae; palpi cylindrical, dark brown with yellow setae; mystax with yellow macrosetae ( Fig. 2A ); antennae placed on upper third of head; scape light brown, gray pollinose, with dark brown macrosetae, longer on ventral surface, pedicel three fourths of scape length, orange-brown, gray pollinose, with dark brown macrosetae, flagellum light brown, gray pollinose, strongly pointed at apex, two times longer than scape and pedicel combined, first flagellomere light brown, posterior ones and stylus dark brown.

Thorax: cervical sclerite covered with golden pile; pronotum light brown, gray pollinose, with yellow setae and macrosetae; scutum light brown with golden pile and three dark brown longitudinal stripes, central stripe originating on anterior margin, pointed apically, lateral stripes originating beyond transversal suture and divided in three portions, anterior and middle portions equal in length and width, posterior portion the same length but only a fourth width of both anterior portions ( Fig. 3A ); scutellum light brown, gray pollinose with sparse short dark brown macrosetae; pleurae dark brown, golden pollinose; anatergite with yellow setae; anepisternum with dark brown macrosetae and yellow setae, mediotergite with yellow setae; katepisternum, anepimeron, subalar sclerite, katepimeron, and meron bare; katatergite with transverse row of yellow setae; metepisternum with tuft of yellowish brown setae on lower third; halter with stem light brown, knob darker.

Legs: coxae light brown golden pollinose; prothoracic coxae with long yellow setae and macrosetae on anterior surface and on apical half of the posterior surface; mesothoracic coxae with long yellow setae and macrosetae on apical half of anterior, anterodorsal, and posterior surfaces; metathoracic coxae with yellow setae and macrosetae on apex of anterior and posterodorsal surfaces; femora yellowish brown except for dark brown area on anterodorsal surface; prothoracic femur with long yellow setae on basal half of anteroventral surface, short dark brown macrosetae on dorsal surface; mesothoracic femur with dark brown macrosetae on anterodorsal surface, row of dark brown macrosetae on anterior and ventral surfaces, short dark brown macrosetae on dorsal surface; metathoracic femur with row of yellow macrosetae on anterodorsal surface, row of dark brown macrosetae on anteroventral surface, dark brown apical macrosetae on posterodorsal surface, row of yellow macrosetae on posteroventral and ventral surfaces; tibiae yellowish brown; prothoracic tibia with dense yellow pile on ventral surface, entirely covered with short dark brown macrosetae, basal dark brown macroseta on anterodorsal surface, medial dark brown macroseta on posterodorsal surface, row of dark brown macrosetae on posteroventral surface, dark brown and yellow apical large macroseta; mesothoracic tibia entirely covered with short dark brown macrosetae, medial dark brown macroseta on posterodorsal and anterodorsal surfaces, dark brown macrosetae on ventral surface, medial dark brown macroseta on posteroventral surface, apical spurs dark brown and yellow; metathoracic tibia entirely covered with short dark brown macrosetae, basal dark brown macrosetae on dorsal surface, dark brown macrosetae on anterodorsal and anteroventral surfaces, dense yellow pile on apical third, more concentrated on ventral surface, brown and yellow apical spurs; tarsi yellowish brown with dark brown macrosetae, yellow pile longer on ventral surface.

Wings: cell r 1, m 3 and cup closed and petiolate at wing margin; R 4+5 arises at same level as base of discal; r-m placed medially in discal cell; alula well developed ( Fig. 4 ).

Abdomen: cylindrical and elongate; light brown golden pollinose with short yellow and dark brown pile; tergite I with yellow setae, longer laterally; other tergites with dark brown marginal setae, long yellow macrosetae laterally ( Fig. 5 ). Distiphallus as long as gonostylus ( Fig. 6 ); Aedeagal apodeme elongate, ovoid in shape, three fourths length of endoaedeagal process; aedeagal paramere slender with sharpened apex; distiphallus trifurcate with apex curved upwards ( Fig. 7 ), hook-shaped in lateral view; gonostylus six times longer than wide, with beak-like apex ( Fig. 8 ).

Female: similar to male, except: metathoracic femur with yellow macroseta on basal third of anterodorsal surface, apical macrosetae dark brown and yellow on dorsal surface, row of yellow macrosetae on posterior and posteroventral surfaces, row of dark brown macrosetae (in some females of type series, basal macroseta of this row yellow) on anteroventral surface; abdomen with long dark brown macrosetae laterally from tergite V to apex (some females have same pattern as males); spermatheca with three rounded reservoirs, two times longer than wide; ejection apparatus membranous, one third of duct length, two times its width, joining together to form single common duct; valves of ejection apparatus rounded; ducts almost three times longer than the reservoir ( Fig. 9 ). Furca elongate, with long arms, thin and convergent with pointed apex; furcal apodeme present; inner margin of basal portion “U” shaped, outer margin “V” shaped. ( Fig. 10 ).
