ETYMOLOGY: The species epithet is a name in apposition taken from the type locality.

DIAGNOSIS: Males of O. manderano can most easily be distinguished from those of other Opopaea species in particular by the cymbiobulbus that tapers anteriorly and has a tip that terminates in a long, thin,

662. Dorsal view. 663. Ventral view. Scale bars: 0.2 mm.

sclerotized extension, which points forward (figs. 596, 597, 600, 601). Females of O. manderano can easily be recognized by a short and narrow U-shaped postgynum depression, which is interrupted medially, and a scutal ridge that bears two parmulae, one on top of the other in its median part: a large and triangular one below, and a round and small one above (figs. 582, 602, 603).

DESCRIPTION: Male (holotype) (PBI_ OON 3883). Medium-sized species. Total length 1.49. Color: orange to yellowish orange. Carapace: pars cephalica not elevat- ed posteriorly with one row of two sets of three denticles, carapace anteriorly narrowed to about one third its maximum width. Carapace anterolateral corners without sclerotized triangular extension. Clypeus low, not rebordered. Chilum absent. Eyes medium sized. ALE largest. ALE oval, PME squared and PLE circular; PME darkened compared to other eyes, posterior eye row straight viewed from above, procurved from front; ALE separated by their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide with radial furrows between coxae, surface smooth and shiny, without pits, posterior part more or less wide and more or less triangular toward posterior edge. Lateral margins between coxae III unmodified, without lumps; setae sparse, dark, needlelike, densest laterally, originating from surface, without hair tufts (figs. 618–621). Palp posterior margin with two protuberances, a large proximal one and a small more or less sharp distal one. Palpal fenestra small and elliptic, located at one third the length of the palp, fenestral top thin, sclerotized, rising slightly toward tip (figs. 139, 140, 622, 623, 626, 627, 630– 638).

Female (paratype from Manderano) (PBI_OON 3883). Total length 1.61. As in male but larger, color orange, abdomen oval, and not flattened toward posterior end, ventral scutum more or less rectangular. Postgynum depression lateral edges more or

less thick internally. Scutal ridge thin, sclerotized, and divided (figs. 582, 602, 603).
