Antillocladius herradurus View in CoL new species
( Fig. 8 View FIGURE 8 A–G)
Type material: Holotype male, MEXICO: Campeche Province, Reserva Biosphere Calakmul, Zona Arqueològica, Aguada Grande, 18°07'26.7''N, 89°48'56.7''W, 19.ix. 1996, 265 m a.s.l., light trap, A. ContrerasRamos et al. ( ZMBN, type no. 399, slide mounted in Canada balsam).
Diagnostic characters: The male imago can be separated from other members of the genus by having a few setae apically on wing membrane; squama with a few setae ; costa barely extended; acrostichals starting in front, anterior ones hairlike, posterior ones scalpellate; virga short; anal point triangular, tapering to blunt apex, with strong lateral setae ; and inferior volsella strongly projecting posteriomedially, ending in two rounded lobes.
Etymology: From Spanish, herradura, meaning horseshoe, referring to the shape of the virga .
Male (n = 1).
Total length 1.89 mm. Wing length 1.06 mm. Total length / wing length 1.78. Wing length / length of profemur 2.32. Coloration brown, thorax pale with brown vittae, tarsi of all legs light brown.
Head. ( Fig. 8 View FIGURE 8 A) AR 1.13, ultimate flagellomere 372 µm. Temporal setae 10, including 3 inner verticals, 4 outer verticals and 3 postorbitals. Clypeus with 5 setae . Tentorium, stipes and cibarial pump as in Fig. 8 View FIGURE 8 B; tentorium 113 µm long, 18 µm wide at sieve pore; stipes 99 µm long. Palpomere lengths in µm: 15, 35, 87, 76, 102. Third palpomere with 2 sensilla clavata subapically, longest 12 µm long.
Thorax ( Fig. 8 View FIGURE 8 C). Antepronotum with 4 setae . Dorsocentrals 8; acrostichals 14, of which the 2 anterior broadly hairlike, the 12 posterior scalpellate, starting close to antepronotum; prealars 3. Scutellum with 6 setae .
Wing ( Fig. 8 View FIGURE 8 D). VR 1.38. Costal extension 28 µm long. Brachiolum with 1 seta, other veins bare, wing membrane with 2 setae in cell r4+5. Squama with 4 setae .
Legs. Spur of front tibia 44 µm long, spurs of middle tibia 28 µm and 21 µm long, spurs of hind tibia 40 µm and 21 µm long. Width at apex of front tibia 29 µm, of middle tibia 29 µm, of hind tibia 37 µm. Hind tibial comb with 12 setae , shortest seta 19 µm long, longest seta 29 µm long. Lengths (in µm) and proportions of legs as in Table 6 View TABLE 6 .
Hypopygium ( Fig. 8 View FIGURE 8 E–G). Anal point 55 µm long, 35 µm wide at base, with 18 strong lateral setae , void of microtrichia except at base. Laterosternite with 6 setae . Phallapodeme 81 µm long. Transverse sternapodeme arcuate, with weak, rounded oral projections; 57 µm long. Virga apparently consisting of 2 spines, 18 µm long. Gonocoxite 137 µm long, with well developed, setoff inferior volsella. Gonostylus 68 µm long, megaseta 17 µm long. HR 2.02, HV 2.78.
