Abstract: Dolichogenidea arenal Fernandez-Triana & Boudreault sp. nov. Fig. 30 A – F Type material. Holotype. Costa Rica • Female, CNC; Alajuela, Arenal Volcano, northern slope; 550 m; 26–27.ix.1972; J. Helava leg.; Voucher code: CNC 1179955. Diagnostic description. Fore wing veins r and 2 RS meeting at a strong angle; T 1 mostly parallel-sided but narrowing towards posterior margin near its posterior half, its length medially ~ 3.0 × its width at posterior margin and its width at anterior margin 1.4 × its width at posterior margin; T 2 length medially 3.0 × its width at posterior margin; ovipositor sheath 0.75 × as long as metatibia; pterostigma uniformly colored, mostly brown to pale brown; pro- and mesocoxae yellow-white, metacoxa mostly yellow with small brown spot on anterior 0.2; metafemur and metatibia mostly yellow or yellow-white, with brown spot on posterior 0.3 and 0.1 respectively; body length: 2.63 mm; fore wing length: 2.72 mm. Among species with T 2 not strongly sculptured, D. arenal is distinctive based on strong angulation of fore wing veins r and 2 RS, as well as leg color, shape of T 1 and T 2, ovipositor sheath lengths, and body size. Distribution. Costa Rica. Biology. No host data available. DNA barcoding data. No data. Etymology. Named after the type locality, the Arenal Volcan, in Costa Rica.
