Pintomyia (Pifanomyia) duckei   sp. nov ( Figure 1 View Figure 1 )

Male: Small insect, 1984 (1766 and 1790) in length (thorax + abdomen), generally of medium brown color, subtly contrasting with lighter pleura. Head ( Figure 1d View Figure 1 ): length 316 (316 and 342), from post-occiput to clypeus apex; maximum width 297 (310 and 323); length/width ratio 1.06 (1.02 and 1.06). Normal eyes, length 177 (177 and 190); width 126 (126 and 120). Incomplete interocular suture; diameter of ommatidia 13 (13 and 13); interocular distance 76 (63 and 95), equivalent to 5.8 (4.8 and 7.3) ommatidia diameters. Completechitinous arch and pigmented spotsform a tenuous perpendicular line, irregular, extending to the middle of the clypeus. Unarmed cibarium and pharynx; length 141 (135 and atrophied), with thin striations in the 1/4 distal. Labrumepipharynx length 184 (190 and 193); labial suture joined in furca. Each flagellomere has a pair of simple ascoids, short and approximately at the same level, inserted in the basal limit of the 1/3 distal, not reaching the apex of the respective flagellomere, except in FI, where they are implanted just beyond the half of the structure, with the inner ascoid more basal than the outer ascoid; in the absence of FXIV, the possibleantennal formula is: FI─FXI2, FXII1, FXIII0. Palpus length 652 (603 and 671). Length of the palpal segments: PI = 34 (37 and 34), PII = 104 (104 and 104), PIII = 116 (122 and 126), PIV = 92 (89 and 95), PV = 306 (251 and 312). Palpal formula:, PV being larger than PI+PII+PIII. Newstead’ssensillae scatteredon the medial inner face of PIII.

Thorax: length 430 (456 and 448), from the anterior margin of the pronotum to the posterior margin of the metanotum. Color: light brown pronotum, paratergite, mesonotum, metanotum and coxae, contrasting smoothly with clearer pleurae. Presence of ventro¬cervical sensillae and 2 (2 and 3) proepimeral setae. Anepisternum with 7 (7 and 6) upper setae, and 2 lower setae; presence of pilosity on the frontal marginof the catepisternum. Wing ( Figure 1e View Figure 1 ): length 1329 (1367 and 1348); width 386 (430 and 418), length being about 3.5 times the width. Wing venation: alphalength 234 (278 and 278); beta 202 (177 and 158), gamma 234 (232 and 234); delta 63 (44 and 63), pi 76 (76 and 63), R5905 (918 and 962), alpha and gamma being of the same length. Legs: lost. Abdomen: length 1554 (1310 and 1342), from first tergite to the gonostylus apex. Terminalia ( Figure 1a View Figure 1 , Figure 1b View Figure 1 , Figure 1c View Figure 1 ): Gonostylus length 89 (89 and 89), width 38 (38 and 38), with two well developed and thick spines (1 apical and 1 subapical external), in addition to a reduced and very thin spine on the inner median face, and presence of subapical spiniform seta. Gonocoxite short and very wide (length less than or equal to twice the width), length 228 (240 and 221), width 120 (114 and 120), with an extensive and salient sclerosed longitudinal range in the internal basal margin. In the holotype, each gonocoxite has one basal tuft of 5 long setae, slender from the distal half, curved upwardly toward the structure, and arranged in a longitudinal row. In the internal distal 1/3 of the gonocoxite, a diffuse group of 20 or more simple, long and semi-deciduous setae is evident. In the anomalous specimens, some of these characters are altered and will be discussed later. Paramere simple, wide or inflated, with slightly convex dorsal margin, length 272 (285 and 285), width 63 (57 and 63), with narrowpreapical. Apex of the paramere ( Figure 1a View Figure 1 ) slender and very short, folded laterally or on the structure, provided with a row of simple and uniform setae, on the dorsal surface. Aedeagus coniform, well sclerosed, with slender apex. Epandrial lobe length 221 (221 and 240), width 32 (32 and 32). Sperm pump length 101 (101 and 98), ejaculatory apodeme (piston) length 76 (76 and 83), ejaculatory ducts length 410 (407 and 410), striated in the distal half, with dilated apexes, filaments about 4 times the length of the pump ( Figure 1c View Figure 1 ); cercus subtriangular.

Female: unknown.
