Spiroberotha sanctarosae Adams, 1989

Diagnosis. Forewing length 5–6 mm; hindwing length 4–5 mm. Frons with a brown W-shaped mark ( Fig. 1 c). Scape pale brown, densely covered ventrally with long, brown or ocher setae ( Fig. 1 c). Notal region with a wide pale longitudinal band, lateral borders brown; setae relatively long, scattered, with dark brown bases ( Fig. 1 d). Fore- and hindwing weakly falcate, lacking long and abundant pilosity in alcohol; forewing veins speckled with small brown spots that extend into the membrane ( Fig. 1 e); a single crossvein in the radial field; pterostigma pale reddish brown; dark brown spots on the base of Rs + MA and crossvein r-rs; 5-7 inner gradate crossveins, aligned, some brown pigmented; a single outer gradate crossvein. Hindwing membrane hyaline, except for a small brown spot on the Sc area, near to pterostigma ( Fig. 1 e); three crossveins in the radial field; pterostigma pale brown. Ectoproct + tergite 9 with posterior region densely covered with brown setae; posteroventral margin with curved projections, directed inward (Fig, 2b); posterior margins of sternites 8 and 9 each with pair of lateral projections with a single spur or seta at the apex ( Fig. 2 b), the first strongly curved dorsad, the second directed caudally ( Fig. 2 a, b). Mediuncus coiled, spiral-like, forming 3.5–4 turns; apices of ninth gonocoxites convergent very close together (Fig. c, d); hypandrium internum triangular ( Fig. 2 f).

Adult flight period. Adults were collected during March and September. S. sanctarosae has been recorded in the literature in the months of December to April (Adams, 1989) and from December through May (Penny, 2002).

New locality records. Colombia, Magdalena, Parque Nacional Natural Tayrona; Bolívar, Zambrano.

Material examined. Magdalena, PNN Tayrona, Neguanje, 11°20’N – 74°02’W, 10 m, trampa Malaise, 9-27- IX-2001, R. Henrriquez, cod 2137, 33 (IAvH); Bolívar, Zambrano, papayo, Gmelina arborea , trampa de luz, H.M, M.A, M. G., III-1999, 43 (CEFUDFJC).

Bionomy. The specimens were collected in Malaise traps, some of them in plantations of the introduced tree Gmelina arborea (Verbenaceae) at the Caribbean region of Colombia, where termite colonies of Coptotermes sp. ( Rhinotermitidae ), Microcerotermes sp., and Amitermes foreli Wasman (Termitidae) are common (Pinzón et al., 1999). Individuals of both locations had pollen grains in their guts.
