Type material.
Holotype male, slide-mounted: Mexico, Campeche, Calacmul, Ejido Nuevo Becan, El Chorro, 18°35'26"N, 89°15'29"W, 130 m a.s.l., 30.iv.1997, light trap, A. Contreras-Ramos et al. leg. (ZMBN).
Etymology.
Named after the Maya people, who used to live in the area. 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: pale brown species; wing without markings; tergite IX without setose dorsal lobe(s) or spine; anal point spatulate; superior volsella slender, curved, tapering; gonostylus curved, with strong setae on protruberance on inner margin in basal one-third.
Description.
Male imago (n = 1). Total length 2.43 mm. Wing length 1.12 mm. Total length/wing length 2.17. Wing length/length of profemur 2.15.
Colouration. Pale brown. Wing membrane without dark markings.
Antenna. AR = 0.18. Thirteenth flagellomere 112 µm long.
Head. Temporal setae 4 in single row. Clypeus with 13 setae. Tentorium and stipes not measurable. Palp segment lengths (in µm): 21, 28, 65, 117, 144. Third palpomere with 2 sensilla clavata subapically, longest 19 µm long. Fifth palpomere/third palpomere 2.22.
Thorax. Dorsocentrals 8 in single row, acrostichals 8, prealars 2. Scutellum with 2 setae.
Wing. VR = 1.44. Brachiolum with 1 seta, R with 10 setae, R1 with 12 setae, R4+5 with 15 setae, remaining veins bare.
Legs. Spur of fore tibia 48 µm long including 21 µm long scale. Mid-tibia with 1 spur, 26 µm long; hind tibia with 2 spurs, 25 and 33 µm long. Combs of mid-tibia 12 µm long, of hind tibia 17 µm long. Width at apex of fore tibia 36 µm, of mid-tibia 40 µm, of hind tibia 44 µm. Lengths and proportions of legs as in Table 9 View Table 9 .
Hypopygium (Fig. 10A, B View Figure 10 ). Tergite IX without lobes, with 8 setae above anal point and 5 somewhat weaker setae to each side of anal point. Anal point spatulate, 36 µm long, maximum width 11 µm. Tergite bands continuous. Laterosternite IX with 2 setae. Phallapodeme 48 µm long; transverse sternapodeme 27 µm long. Gonocoxite 104 µm long. Inferior volsella curved, 55 µm long, 14 µm wide subapically, with microtrichia and 4 strong apical setae. Superior volsella slender, curved, tapering, 54 µm long, 11 µm wide at base, 3 µm wide subapically, covered with microtrichia and with 2 weak apical setae. Median volsella consisting of two small tubercles, about 4 µm long, each with single setae at apex, longest 15 µm long. Gonostylus 131 µm long, curved, with single, strong setae on protuberance on inner margin at 27 µm from base, setae 21 mm long. HR = 0.79. HV = 1.85.
Female adult and immatures.
Unknown.
Remarks.
