DIAGNOSIS: Both sexes can easily be separated from members of all the other species detailed below by the much weaker scuta on the abdomen (figs. 121–123, 135, 136).

MALE (PBI_OON 38284, figs. 1–30, 121–134): Total length 1.40. Carapace yellow, elevated portion of pars cephalica finely reticulate, sides finely reticulate. Sternum yellow, finely reticulate. Mouthparts yellow, endites unmodified. Abdomen with dark patches visible through dorsal scutum. Scutopedicel region with numerous elevations not fused into ridges. Dorsal scutum pale orange, punctate, covering most of abdomen length, width. Postepigastric scutum pale orange, covering about ¾ of abdominal length. Embolus light, with narrow basal process extending as far distally as sail-shaped flange.

FEMALE (PBI_OON 38284, figs. 31–60, 135–144): Total length 1.61. Postepigastric scutum short, almost rectangular, covering about half of abdominal length. Posterior receptaculum wide, bordered anteriorly by wide poreplate, dorsal and ventral edges of poreplate distinct, ventral edge sinuous.

DISTRIBUTION: Pantropical.

SYNONYMY: Most of the synonyms seem to be due to generic-level misplacements; of prior workers, only Saaristo (2001) correctly associated his specimens with Pelicinus , and he anticipated some of the new synonymies as well.
