description: Ponsoonops panto, new species   Figures 259–273  
NOTE: Males and females have not been collected together, but are generally a good match. It must be pointed out that the female epigyne and vulva seem to be moderately deformed (figs. 272, 273).  
TYPES: Male holotype and one male paratype from a Berlese sample of concentrated floor litter at base of log and cut stump taken at an elevation of 1524 m at a site west of Nueva California, Finca Palo Santo, Chiriquí, Panama (Mar. 10, 1959, H.S. Dybas), deposited in FMNH (56513 PBI_OON 10747).  
ETYMOLOGY: The specific name is a noun in apposition, a shortened anagram taken from the type locality.  
 DIAGNOSIS: Males resemble those of P. boquete, P. lerida, and P. vuena in having an embolus with a median protrusion, and a narrowed, distinctly elongated embolus tip (fig. 268). They differ in having a conductor that is shorter than the embolus with short, narrow distal projections (rather than distally truncated in P. lerida, pointed and longer than embolus in P. boquete and P. vuena). In addition, they differ from P. lerida in having a ridge-shaped median protrusion at the embolus (rather than mound-shaped). The female diagnosis is problematic due to possible deformation of the epigynal area. It seems to differ in having a relatively short and broad-stalked anterior genitalic process (figs. 273), and an indistinctly pocketlike, broad posterior genitalic process.   
MALE (PBI_OON 10747, figs. 259–269): Total length 1.42. Leg spination: tibiae: I v4-2-2; II v4-2-1p; IV p0-1-0, v0-0-2, r0-1-0; metatarsi: I, II p1-0-0, v2-2-2; IV p0-1-0. Sperm pore circular. Tarsal organ on palpal cymbium with distal receptor appearing bifid. Embolus broad, tube shaped, longitudinally folded, with ventral slit and ventroprolateral opening, midway with distinct rounded ridge, prolaterad protruding, tip narrowed, elongated, opening retrolaterally rebordered, platelike with small ventral protrusion; conductor originates at embolus base, bandlike elongated, midway moderately twisted, broad ending with several short, narrow prolongations, as long as embolus.  
FEMALE (PBI_OON 21112, figs. 270–273): Total length 1.79. Leg spination: tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-1p; IV p0-1-0, v1-0-2; r0-1-0; metatarsi: I, II p1-0-0, v2-2-2; IV p0-1-0. Genitalia externally probably partly distorted (e.g. postepigastric scutum, fig. 272); internally with median protruding part of large genital plate wider than long; anterior genitalic process broad and relatively short stalked, apex enlarged; posterior genitalic process indistinct, pocketlike, broad, weakly sclerotized.
