Spiroberotha sanctarosae Adams 1989

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, 2 b); 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.

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.Published as part of Ardila-Camacho, Adrián, 2013, First record of Beaded Lacewings (Neuroptera, Berothidae) from Colombia, pp. 159-164 in Zootaxa 3669 (2) on page 160, DOI: 10.11646/zootaxa.3669.2.7, http://zenodo.org/record/21830

Can the Vegetation Structure and Composition in Urban Green Spaces Determine Diversity of Green Lacewings (Neuroptera: Chrysopidae)?

Green spaces represent the only natural areas in several cities around the world, providing good shelters for the local fauna. Based on this premise, many ecological studies have been conducted focused on these areas. Most of these works are about insects, particularly butterflies and beetles. Our study is centered on a different group: green lacewings (Neuroptera: Chrysopidae). These insects exhibit a similar feeding behavior to some other groups, such as beetles. We estimated diversity, richness, distribution, abundance and similarity employing two methods: sweep netting and suction trapping. Also, oviposition hosts were identified in 20 different green spaces. Approximately 740 specimens were collected representing 15 species in five genera. Seven species are new state records for Yucatán, Mexico. We identified about 300 species of plants, if which 75 are considered ovipositional associated hosts. Our work is the first of its kind, employing green lacewings in an urban ecological model and additionally providing new information about chrysopids in South Mexico. We encourage the conduct of similar studies not only in Mexico but also in other Central and South American countries
