Type Material

Holotype: male, here designated. COLOMBIA. Santander. Charalá. Virolin. Mar 1981. 18-III. Santander. Charalá. Virolin. Heteroscelis lepida Stål, 1862 —ICN. Det : F. Rua Alvear, 2006. ICN 055894 . (6.1080, -73.2004). Deposited in: ICN ( Fig. 30 ).

Paratype: male, here designated. COLOMBIA. Boyacá. Villa de Leyva. SFF Iguaque . 05°38’N 73°29’W WGS 84 . 2450 m. Captura manual. 19.VIII.1998. J. Castro. IAvH-E-VillaDeLeyva . Deposited in: IAvH-E ( Fig. 31 ).

Etymology. Named after the father of the first author, Vandemberg de Freitas Sampaio (in memoriam), who made a great effort to provide a good education for his children, but unfortunately could not reap the fruits he sowed.

Diagnosis. Head, thorax and abdomen orange to red, coria iridescent-blue, radial vein usually reddish; foretibial length on average 9.5x larger than the width of the dorsal expansion ( Fig. 30 , F).

Description

HEAD: Mandibular plates slightly surpassing clypeus, anteriorly rounded, separated at apex; head length anterior to the eyes shorter than 2/3 of the total length of the head ( Fig. 30 , D); proportion of labiomeres: I<II>III<IV; proportion of antennomeres: I<II<III, IV and V missing.

THORAX: Coria iridescent-blue, uniformly punctured, longer than the scutellum, not reaching the posterior margin of connexival segment VI; radial vein usually reddish; membrane dark, surpassing posteriorly the abdomen; metapleural evaporatoria not surpassing posteriorly the anterior limit of coxae; peritreme disc-shaped, surpassing half the pleural width; apex of peritreme rounded, posterior margin arched, convex, anterior margin almost straight ( Fig. 30 , E).

ABDOMEN: Uniformly punctured; urosternite III tubercle not surpassing the posterior margin of metasternum; posterior angles of urosternites III to VII ending in minute spine ( Fig. 30 , B).

Male:

MEASUREMENTS (n=1). Head length 1.52; width 1.36; pronotum length 1.84; width 4.08; scutellum length 2.48; width 3.04; length of antennomeres: I 0.32, II 0.64, III 1.04, IV–, V–; length of labiomeres: I 0.60, II 0.90, III 0.40, IV 0.50; width of foretibal expansion 0.24; width of abdomen 3.60; total length 6.72.

GENITALIA: Pygophore ( Fig.32 ): setae denser on posterolateral angles; dorsal rim concave; ventral rim sinuous, medially concave; segment X with surface corrugated; head of parameres laterodorsally directed in posterior view.

Remarks: This species is quite similar to H. lepida , however, without considering the difference in color, H. vandembergi sp.nov. also differs from H. lepida in the proportion of the area anterior to the eyes, and in the proportion of the dorsal foretibial expansions in relation to the femur, a trait that does not vary within the other species of the genus.

Female unknown.

Distribution: Colombia ( Fig. 1 ).
