Costarina macho , new species ( Figures 315–325 )

TYPES: Male holotype, female allotype, and male paratype sifted from forest litter taken at an elevation of 2850 m in the Reserva Forestal Río Macho , km 70 on the Inter-American Highway, 9°39′N, 83°51′W, Cartago, Costa Rica (Mar. 22–26, 1999; J. Miller), deposited in USNM (PBI_OON 27842) .

DIAGNOSIS: Males resemble those of C. cuerici (cf. figs. 279–289 and C. junio (cf. figs. 290–300) but the lightly sclerotized portion of the distal embolar prong is much smaller and the distal prong is wider than in those species (figs. 315–320). Females resemble those of C. cuerici but have a much narrower, rectangular genital atrium (figs. 324, 325).

MALE (PBI_OON 27842, figs. 315–320): Total length 2.46. Both processes on endite basally widened. Femur II p0-0-1; tibia I v4-4-2. Embolus proximal prong elongated, narrow; distal prong reflexed ventrally, with narrow translucent flange on prolateral side (N = 6).

FEMALE (PBI_OON 27842, figs. 321–325): Total length 2.51. Spination typical. Genital atrium short, anterior margin medially excavated, posterior margin weak (N = 6).

DISTRIBUTION: Cartago.
