( Figs 32–34 , 44–46 )

Oiovelia spumicola Spangler, 1986: 438 (original description).

Oiovelia spumicola: MAZZUCCONI & BACHMANN (1997b) : 68 (notes on immature stages).

Type locality. Venezuela, Amazonas, Cerro de la Neblina.

Type material examined. PARATYPES: VENEZUELA: TERRITÓRIO FEDERAL AMAZONAS: 1 ♂ 1 ♀ (apt) ( INPA), 1 ♀ (apt) ( MZSP), Cerro de la Neblina, 1450 m a.s.l., 00º52 ' N / 65º58 ' W, 25–28.ii.1985, P.J. Spangler, P.M. Spangler & R.A. Faitoute coll.

Dimensions. Apterous male (n = 1; mm). BL 3.10; HL 0.50; HW 0.60; ANT I 0.62, ANT II 0.33, ANT III 0.27, ANT IV 0.40; EYE 0.12; PL 0.97; PW 1.05; FORE LEG: FEM 0.85, TIB 0.83, TAR I 0.06, TAR II 0.06, TAR III 0.35; MID LEG: FEM 0.92, TIB 0.97, TAR I 0.06, TAR II 0.10, TAR III 0.40; HIND LEG: FEM 1.15, TIB 1.30, TAR I 0.07, TAR II 0.10, TAR III 0.40.

Apterous female (n = 1; mm). BL 3.55; HL 0.55; HW 0.62; ANT I 0.60, ANT II 0.30, ANT III 0.26, ANT IV 0.43; EYE 0.13; PL 0.97; PW 1.05; FORE LEG: FEM 0.92, TIB 0.83, TAR I 0.06, TAR II 0.06, TAR III 0.37; MID LEG: FEM 1.05, TIB 1.06, TAR I 0.09, TAR II 0.11, TAR III 0.38; HIND LEG: FEM 1.22, TIB 1.32, TAR I 0.07, TAR II 0.15, TAR III 0.41.

Diagnostic characters. This species is easily identified and differentiated from all other species by the yellowish general color of the body and appendages ( Figs 32–34 ). Also, the male has dark central areas on sternites V–VI ( Fig. 34 ), proctiger with a small acute process on the dorsal surface, and paramere broad at base, tapering to apex, which is hook-shaped ( Fig. 46 ).

Differential diagnosis. The apterous and macropterous forms are known in both sexes. However, it was not possible to examine macropterous specimens in this study. SPANGLER (1986) mentions that their form is similar to apterous specimens, differing from the last mainly in dark brown color of the dorsal surface of head, sides of thorax and abdominal sternites. In addition, the pronotum is reddish brown in anterior third and the fore wings are dark brown, with a basal creamy yellow area.

Distribution and habitat. Venezuela ( SPANGLER 1986).

This species is known only from the type locality, Tepui Cerro de la Neblina, on the border of Venezuela and Brazil. It may possibly be an endemic species of this geographical region. All specimens were collected on foam masses formed in black water streams above 1450 m a.s.l. ( SPANGLER 1986).
