Compterosmittia croizati View in CoL new species
( Fig. 19 View FIGURE 19 A–E)
Type material: Holotype male, VENEZUELA: Aragua, Parque Nacional Henri Pittier, Rancho Grande, 10°21.047'N, 67°41.198'W, 16–18.ix. l1999, about 1000 m a.s.l., sweep net & light trap, T. Andersen ( MIZA, slide mounted in Canada balsam). Paratypes: Brazil: Santa Catarina State, São Bento do Sul, 26°19'25.6''S, 48°18'26.5''W, 2 males, 13–16.x. 2001, 660 m a.s.l., Malaise trap, M.V. Yamada (1 MZUSP and 1 ZMBN).
Diagnostic characters: The male imago differs from C. nerius only in having megaseta not dentate.
Etymology: Named in honour of the Venezuelan biogeographer L. Croizat.
Male (n = 1–3).
Total length 1.68–1.85 mm. Wing length 1.05–1.14 mm. Total length / wing length 1.57–1.66. Wing length / length of profemur 2.46–2.62. Coloration brown, thorax dark brown, tarsi of all legs light brown.
Head. AR 0.66–0.73, ultimate flagellomere 224– 280 m. Temporal setae 5–9, including 1–2 inner verticals, 1–2 outer verticals and 2–4 postorbitals. Clypeus with 12 setae . Tentorium, stipes and cibarial pump as in Fig. 19 View FIGURE 19 A; tentorium 110–112 m long, 7–8 m wide at sieve pore; stipes 97–98 m long, 18 m wide. Palpomere lengths in m: 15–22, 26–32, 55–62, 48–55, 69. Third palpomere with 2–3 sensilla clavata subapically, 14–17 m long.
Thorax ( Fig. 19 View FIGURE 19 B). Antepronotum 0–1 seta. Dorsocentrals 7–8; acrostichals 9–11, all scalpellate, starting at one third from antepronotum; prealars 3–4. Scutellum with 4 setae .
Wing ( Fig. 19 View FIGURE 19 C). VR 1.43–1.53. Costal extension 148–168 m long. Brachiolum with 1 seta, R with 3 setae , R4+5 with 0–4 setae , other veins bare, wing membrane bare. Cu slightly sinuous. Squama bare.
Legs. Spur of front tibia 32–36 m long, spurs of middle tibia 25 m and 17–21 m long, spurs of hind tibia 39–41 m and 18–19 m long. Width at apex of front tibia 25–32 m, of middle tibia 21–29 m, of hind tibia 30– 36 m. Hind tibial comb with 10–12 setae , shortest seta 18–21 m long, longest seta 36–39 m long. Lengths (in m) and proportions of legs as in Table 15 View TABLE 15 .
m) and proportions of legs of Compterosmittia croizati new species.
Hypopygium ( Fig. 19 View FIGURE 19 D–E). Anal point 29–34 m long, 25–27 m wide at base, with 9–16 strong lateral setae , void of microtrichia except at base. Laterosternite IX with 3–4 setae . Phallapodeme 59–62 m long. Transverse sternapodeme nearly straight, with rounded oral projections, 55–62 m long. Virga absent. Gonocoxite 135–139 m long, with long, low inferior volsella. Gonostylus 62–65 m long, megaseta 14–16 m long. HR 2.13–2.24, HV 2.71–2.98.
Remarks: The only significant difference between C. croizati and C. nerius consists in the nondentate megaseta. This could perhaps be intraspecific variation and C. croizati thus a synonym of the apparently widespread C. nerius .
