TYPES: Male holotype and female paratype from Kartabo, Cuyuni-Mazaruni region, Guyana (6 ° 09N, 58 ° 09W), July 03, 1982, to July 12, 1982, K., R. Schmidt col. ( AMNH PBI_OON 40575; AMNH PBI_OON 1018) .

ETYMOLOGY: The specific name, to be treated as a Latin adjective, refers to the type locality.

DIAGNOSIS: Males of Simlops guyanensis differ from those of S. bodanus and S. guatopo by the combined presence of short embolus, without basal constriction, and a massive hyaline conductor, without basal sclerotizations (figs. 316, 317). Females do not have a separated dorsal abdominal scutum, but the frontal margin of the epigastric scutum presents a median protrusion (fig. 264); they resemble S. bodanus by the presence of a well-defined posterior receptaculum, but can be readily separated from that species by the T-shaped anteromedian rod (fig. 330).

MALE (PBI_OON 1018, figs. 251–258, 288, 316, 317): Total length 1.83. Carapace dark red-brown; sternum and mouthparts orange-brown, legs orange-brown, without color pattern; abdomen soft portions pale white, abdominal scuta orange-brown. Sternal microsculpture only in furrows. Endites with prolateral process stout laminar, sharply pointed, slightly bent retrolaterally; retrolateral projection small, triangular, slightly curved prolaterally, median process not protruded (fig. 288). Postepigastric scutum almost semicircular, covering about 3/4 of abdominal length. Palp: embolus relatively short, slender, tip pointed apically, conductor as long as embolus, semitranslucent, with dark sclerotized stripe, originating at the bulbus, adjacent to embolar insertion (figs. 256–258, 316, 317).

FEMALE (PBI_OON 1018, figs. 259– 266, 330): Total length 2.34. Dorsal scutum absent. Epigastric furrow medially slightly recurved, not medially sclerotized, without median notch, not connected laterally to anterior spiracles; postepigastric scutum with anterior margin slightly sclerotized, not extending beyond groove connecting posteri- or spiracles, not enlarged laterally around posterior spiracles, without discrete lateral sclerotizations. Genitalia with T-shaped posteromedian rod, anterior end large; transverse bar thin, procurved, without rectangular plate; posterior receptaculum conspicuous, subquadrangular, with sclerotized borders, enclosed by long, parallel lateral apodemes (figs. 266, 330).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from the type locality.
