Ponsoonops sanvito , new species

Figures 1–84

NOTE: The species belongs to the sanvito group (see below).

TYPES: Male holotype and female paratype from a Berlese sample of concentrated floor litter from a slope above a stream taken at an elevation of 1219 m at Estación Biológica Las Cruces, San Vito, 8.76666°N, 82.96666°W, Puntarenas, Costa Rica (Mar. 15, 1973, J. Wagner, J. Kethley), deposited in FMNH (PBI_OON 10646) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males resemble those of the sanvito group in having a distinct ventral slit at the embolus (figs. 14, 15). They differ from all those species, except P. lucha and P. mirante , in lacking a median protrusion at the embolus (figs. 12, 13, 71). They differ from P.lucha in having the embolus and conductor well separated, and from P. mirante in having a sharply pointed conductor tip (rather than broadly rounded). Females differ from others, except those of P. bilzi , in having a relatively small, subspherical posterior genitalic process without distinct duct (with distinct duct in P. lerida ). They differ from those of P. bilzi in having spoon-shaped glands attached to the posterior genitalic process (figs. 45, 82, 84), and only a few short filiform glands at the base of the anterior genitalic process (fig. 83; rather than numerous and long).

MALE (PBI_OON 10646, figs. 1–30, 61–72): Total length 1.41. Leg spination: tibiae: I v4-2- 2; II v4-2-1p; metatarsi: I v2-2-2; II v3-2-2. Sperm pore subcircular. Embolus broad, tube shaped, longitudinally folded, distinct ventral slit with prolateral opening, tip narrowed, elongated, embolus opening oval, distoretrolaterally with small bifid plate; conductor narrow lamelliform, elongated, simply pointed, almost as long as embolus.

FEMALE (PBI_OON 10646, figs. 31–60, 73–84): Total length 1.69. Leg spination: tibiae: I p1-1-0, v4-2-2, r1-0-0; II v4-2-2; IV p0-1-0, v0-0-2, r0-1-0; metatarsi: I p1-0-0, v2-2-2; II p0-1-0, v3-2-2; IV p0-1-0. Median protruding part of large genital plate wider than long; anterior genitalic process narrowly stalked, distinctly enlarged apex; posterior genitalic process subspherical, relatively small, without remarkable duct, weakly sclerotized, distally with spoon-shaped glands.
