Costarina poas , new species ( Figures 111–121 )

TYPES: Male holotype, female allotype, and male paratype from Berlese sample taken at an elevation of 2520–2540 m on the lake trail at Volcán Poás, 10.17442305°N, 84.2375125°W, Alajuela, Costa Rica (Apr. 6, 2002; P. T homas), deposited in INBIO (72382, PBI_OON 31183) .

DIAGNOSIS: Males resemble those of C. cima (cf. figs. 45–55) but have a much longer, distally narrower distal embolar prong (figs. 111–116); females also resemble those of C. cima but have a longer genital atrium and shorter, stronger apodemes (figs. 120, 121).

MALE (PBI_OON 31183, figs. 111–116): Total length 2.35. Endite ventral process relatively wide; dorsal process relatively narrow. Femur I r1-1-0; tibia II v4-4-0; metatarsus II v2-2-0. Embolus distal prong arched, narrow; proximal prong enlarged, translucent, attached to distal prong basally (N = 16).

FEMALE (PBI_OON 31183, figs. 117–121): Total length 2.42. Spination typical. Genital atrium short, wide, with rebordered posterior margin, paramedian apodemal lobes visible through cuticle (N = 7).
