Type material.
Holotype male, slide-mounted: Brazil, Rondônia, Candeias do Jamari, Rio Preto, Ponte de Madeira, 08°52'40"S, 63°38'02"W, 19-20.vii.2012, light trap #01, R. Boldrini & A.S. Fernandes leg. (UFSC). Paratype: 1 male adult, slide-mounted: BRAZIL, Amazonas, Barcelos, Rio Aracá, #9, 69 m a.s.l., 00°24'39"N, 63°23'12"W, 28.vii-06.viii.2009, light trap #3, N. Hamada et al. leg. (INPA).
Etymology.
The specific epithet honours the Karitiana, indigenous people from the Rio Jamari Basin in the Rondônia State (Brazil). The name is to be regarded as a noun in apposition.
Diagnostic characters.
The male can be distinguished from its congeners by the combination of: tergite IX without setose dorsal lobe(s); anal point spatulate; wing unmarked; superior volsella fused to median volsella; gonostylus very long, narrow basally and apically, swollen medially.
Description.
Male imago (n = 2, unless otherwise stated). Total length 3.32-3.78 mm. Wing length 1.71-1.83 mm. Total length/wing length 1.94-2.07. Wing length/length of profemur 2.02-2.06.
Colouration. Head, thorax, legs and abdomen uniformly light brown. Wing membrane hyaline.
Antenna. AR = 0.22 (1). Thirteenth flagellomere 217 µm long.
Head. Temporal setae 9 (1) in single row. Clypeus with 10-11 setae. Tentorium 105 (1) µm long, maximum width 17 (1) µm. Stipes 122 (1) µm long. Palp segment lengths (in µm): 25-35, 27-37, 60 (1), 80 (1), 154 (1). Third palpomere with 3 (1) sensilla clavata subapically, longest 20 (1) µm long. Fifth palpomere/third palpomere 2.57
Thorax. Dorsocentrals 9-13 in single row, acrostichals 12, prealars 2-3. Scutellum with 2 setae.
Wing. VR = 1.33-1.46. Brachiolum with 1 seta, R with 11-14 setae, R1 with 10-12 setae, R4+5 with 3-4 setae at apex, remaining veins bare.
Legs. Spur of fore tibia 59-64 µm long including 17-20 µm long scale. Mid-tibia with 1 spur, 23-25 µm long; hind tibia with 2 spurs, 23-25 and 29-33 µm long. Combs of mid-tibia 15-20 µm long, of hind tibia 20-23 µm long. Width at apex of fore tibia 59 µm, of mid-tibia 59 µm, of hind tibia 64 µm. Lengths and proportions of legs as in Table 5 View Table 5 .
Hypopygium (Fig. 6A, B View Figure 6 ). Tergite IX without dorsal lobes, tapering to apex, with 2-3 median and 8-9 setae to each side of anal point. Anal point spatulate, 55-57 µm long, 17-20 µm wide. Tergite bands well developed. Laterosternite IX with 1-2 setae. Phallapodeme 82-90 µm long; transverse sternapodeme 42-55 µm long. Gonocoxite 138-142 µm long. Inferior volsella slightly curved, 97-107 µm long, 17-20 µm wide medially, with microtrichia and 6-7 simple setae subapically. Superior volsella digitiform, 55-65 µm long, 17-20 µm wide at base, covered with microtrichia and with 4 setae apically. Median volsella fused to superior volsella, consisting of 2-4 small tubercles each bearing single, simple seta, longest 22-25 µm. Gonostylus 204-232 µm long, straight, narrow basally and apically, swollen medially. HR = 0.62-0.70. HV = 1.62-1.63.
