Scaphios napo , new species Figs. 801–823

TYPES: Male holotype and female allotype from Winkler samples of litter taken at an elevation of 2100 m on the circuit trail at Yanayacu Biological Station, Napo, Ecuador (Nov. 25, 2009; B. Baehr, Niarchos Exped. ), deposited in QCAZ (PBI_OON 459) .

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

DIAGNOSIS: Males resemble those of S. yanayacu but have a longer, humped embolus (figs. 809–813); females have the transverse sclerite at the base of the anterior genitalic projection shorter than in that species (figs. 822, 823).

MALE (PBI_OON 459, figs. 801–813): Total length 1.80. PME squared; ALE separated by their radius to diameter, PLE- PME separated by PME radius to PME diameter. Endites with anterior projection beaklike, directed laterally. Leg spination: tibiae III, IV v0-0- 1p. Embolus with distinct hump at about half its length, tip slightly expanded; bulb elongated (figs. 809–813).

FEMALE (PBI_OON 459, figs. 814–823): Total length 2.40. Posterior eye row recurved from above, straight from front; ALE separated by more than their diameter. Leg spination: tibiae III, IV v0-0-2; metatarsi III v0-0-2. Anterior genitalic projection distally triangular, transverse sclerite at its base relatively short, apodemes M-shaped (figs. 822, 823).

DISTRIBUTION: Known only from the Yanayacu Biological Station in Napo province, Ecuador, where it is sympatric with S. yanayacu .
