TYPE: Female holotype from Bolivia: Departamento de La Paz: Provincia de Sud Yungas, Municipio de Chulumani: Paraíso, beating vegetation in yungas forest, 2255 m, Oct. -16.39488°, -067.55847°, 13, 2011, to Oct. 18, 2011, M. Izquierdo, deposited in CBFC, PBI_ OON 42279; same data, 1 female paratype deposited in MACN 28177, PBI_OON 42253; same data, 1 female paratype deposited in MACN 28178, PBI_OON 42280.

ETYMOLOGY: The specific name is a combination of the first letters of three native groups of Bolivia (Moxeño, Yuracaré, and Chiriguanos) and is a tribute to all the ethnicities of that country.

DIAGNOSIS: Females can easily be distinguished by the shape of the internal genitalia with massive anterior receptaculum with lateral projections, two lateral sclerotized plates (asterisk in fig. 197A), long anterior apodemes, and by the presence of widely separated internal pockets (figs. 147A, C, 197A).

MALE: Unknown.

FEMALE (PBI_OON 42279): Total length 1.62. Habitus as in figure 145. CEPHALOTHORAX: Sternum longer than wide, pale orange. Labium rectangular. GENITALIA: As in diagnosis, external pockets absent; anterior receptaculum with massive lateral projections and inconspicuous lumen, two lateral sclerotized structures and two long anterior apodemes; posterior receptaculum

absent, posterior apodeme formed by entire plate (figs. 147A, C, 197A).

rior receptaculum, which is long and heart shaped at the tip, with oval structures at the base and massive sclerotized plates laterally (figs. 147B, D, 197B). MALE: Unknown.

DISTRIBUTION: Known only from the type locality in Bolivia (Departamento de La Paz, map 28 ).

OTHER MATERIAL EXAMINED: None.

ETYMOLOGY: The name is a patronym in honor of Cristian Grismado, colleague, friend, and collector of the type specimen, and with whom we have discussed oonopid diversity and morphology and shared many field trips. DIAGNOSIS: The female of this species can be separated from others by the shape of the ante-
