Reductoonops niltepec, new species (figs. 141–160)

TYPES: Male holotype and male paratype taken 2 miles southeast of Niltepec, 16°32′N, 94°33′W, Oaxaca, Mexico (Aug. 16, 1966; J., W. Ivie), deposited in AMNH (PBI_OON 37321) .

DIAGNOSIS: Members of this species resemble those of R. chamela and R. armeria in retaining the four posterior eyes. Males differ from those of R.armeria in having a much longer base subtending both the embolus and conductor, and from those of R. chamela in having that base wider (figs. 157–160). Females differ from those of R. chamela and R. armeria in having the posterior portion of the anterior genitalic process wider proximally than distally (figs. 144, 145).

MALE (PBI_OON 37321, figs. 141, 146–160): Total length 1.03. Surface of elevated portion of pars cephalica finely reticulate. Eyes six; ALE touching. Sternum without anterior channels, surface finely reticulate, without pits, microsculpture only at sides; setae densest laterally. Labium anterior margin indented at middle. Endite tip with squared, anteromedially directed lobe. Embolus and conductor originating from long, wide common base; cymbium not fused with bulb.

FEMALE (PBI_OON 21105, figs. 142–145): Total length 1.15. Anterior genitalic process with long posterior portion wider posteriorly than anteriorly, short anterior portion greatly widened.
