Diagnosis

Cnodalomyia artigasi sp. nov. can be easily distinguished from C. obtusa and C. papaveroi sp. nov. by the entirely yellow mystax. From C. catarinensis it can be distinguished by the lateral stripes of the mesonotum, which are divided into three portions of the same length in C. catarinensis , where in C. artigasi sp. nov. the posterior portion has half the length of both anterior portions. The gonostylus of C. catarinensis also differs from that of C. artigasi sp. nov., as in the latter the apex is down-curved.

Body length. 12.1–16.8 mm. Wing length: 7.9–15.3 mm.

Ground colour. Light brown.

Male

Head. Face yellowish brown, golden pollinose; frons dark 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 ( Figure 6B View Figure 6 ); antennae placed on upper third of head; scape yellowish brown, grey pollinose, with dark brown macrosetae, longer on ventral surface, pedicel three-quarters of scape length, light brown, grey pollinose, with dark brown macrosetae, postpedicel light brown, grey 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, grey 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 into three portions, anterior and middle portions equal in length and width, posterior portion with half the length and only one quarter the width of both anterior portions ( Figure 6C View Figure 6 ); scutellum light brown, grey pollinose with sparse, short dark brown macrosetae; pleurae dark brown, golden pollinose; anatergite with yellow setae; anepisternum with dark brown macrosetae and yellow setae on upper quarter, mediotergite with yellow setae; katepisternum, anepimeron, subalar sclerite, katepimeron, and meron bare; katatergite with transverse row of yellow macrosetae; metepisternum with tuft of yellow 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 and anterodorsal surfaces, and on apex of posterior surface; metathoracic coxae with yellow macrosetae on apex of anterior and dorsal 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 anterior surface, row of dark brown macrosetae on anteroventral surface, row of dark brown macrosetae on ventral surface, small dark brown macrosetae on dorsal surface; metathoracic femur with dark brown apical macrosetae on dorsal surface, row of yellow and dark brown macrosetae on anterodorsal surface, row of yellow macrosetae on anteroventral surface, row of yellow macrosetae on posterior surface, small yellow macrosetae on dorsal surface; 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, yellow macrosetae on apical half of posteroventral surface, dark brown and yellow, apical, large macroseta; mesothoracic tibia entirely covered with short dark brown macrosetae, with medial dark brown macroseta on dorsal surface, yellow macrosetae on apical third of posterior surface, apical, strong macrosetae dark brown and yellow; metathoracic tibia entirely covered with short dark brown macrosetae, basal dark brown macrosetae on dorsal surface, two rows of yellow and a row of dark brown macrosetae on anteroventral surface, a row of yellow macrosetae on anterodorsal surface, dark brown macrosetae on dorsal surface, dark brown and yellow, apical, strong macrosetae; tarsi yellowish brown with dark brown and yellow macrosetae, yellow pile.

Wings. Cells r 1, m 3 and cu p 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.

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. Aedeagal prongs as long as gonostylus ( Figure 7A View Figure 7 ), with apex curved upwards ( Figure 7B View Figure 7 ), hook-shaped in lateral view; ejaculatory apodeme elongate, ovoid in shape, with one-third of aedeagus’ length; lateral ejaculatory process slender with sharpened apex; gonostylus four times longer than wide, with a sharpened beak-like apex curved downwards ( Figure 7C View Figure 7 ).

Female

Similar to male, except: spermathecae with three spherical spermathecal reservoirs, two times longer than wide; ejection apparatus membranous on basal half and thickened on dorsal half, half of individual spermathecal ducts’ length, two times their width, joining together to form single common spermathecal duct; valves of ejection apparatus rounded; individual spermathecal ducts almost three times longer than the spermathecal reservoir ( Figure 7D View Figure 7 ). 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 ( Figure 7E View Figure 7 ).

Eggs. Enlarged, light brown; exochorion with button-like aeropyles ( Figure 8A View Figure 8 ); chorion composed of pentagonal cells, except for a smooth surface at centre ( Figure 8B View Figure 8 ); micropylar area largely smooth, without grooves, with one central micropyle.
