Costarina paraplena View in CoL , new species ( Figures 12–22 View FIGURES 12–22 )
TYPE: Male holotype from Upala, Aeropuerto 1.1, 10°53′21″N, 85°01′04″W, Alajuela, Costa Rica (Mar. 19, 2010; C. Víquez), deposited in INBIO (PBI_OON 49943) GoogleMaps .
ETYMOLOGY: T he specific name refers to the similarities between this species and C. plena .
DIAGNOSIS: Specimens of this species resemble those of C. plena (cf. figs. 1–11) but can easily be distinguished by the much more pronounced, longitudinally arranged extensions of the lateral arms of the posterior sternal ridge (fig. 18). Males have lost the spinneret scutum and have a longer, more arched proximal embolar prong (figs. 12–17); females can easily be distinguished from those of C. plena by their much shorter genital atrium (figs. 21, 22); and from those of C. superplena (cf. figs. 23–33) by the longer apodemes (figs. 21, 22).
MALE (PBI_OON 49941, figs. 12–17): Total length 1.76. Endite ventral process narrow, with sinuous tip; dorsal process short. Femur I r0-1-1; metatarsus II v2-2- 1p. Embolus distal prong with ventrally directed tip; proximal prong long, arched (N = 14).
FEMALE (PBI_OON 49944, figs. 18–22): Total length 2.31. Metatarsus II v2-1r- 1p. Genital atrium short, much wider than long (N = 22) .
DISTRIBUTION: Widespread in Costa Rica (Guanacaste, Alajuela, Heredia, Limón, and northern Puntarenas) .
