Material examined. Holotype female, 14.2 × 9.7 mm ( LACM CR 1987.167.1), anchialine cave, Grieta de Caleta la Torta, Santa Cruz Is., Galápagos Is., coll. T. M. Iliffe, 8 Jun. 1987 . Diagnosis. Anterolateral margin with teeth broad, lobate. Anterior regions of carapace with slight transverse rows of granules, almost indiscernible, not basally conjoined. Corneas, eyestalks reduced. Area lateral to the orbits with 2 granular ridges linking at level of exorbital angle, first anterolateral tooth, enclosing small, depressed area. Frontal margin angled toward posterior laterally, medial notch relatively large. Chelae unequal, dimorphic; dactylus of major chela with large basal tooth; outer surface of fixed finger, dactylus of minor chela granulated. Ambulatory legs relatively long, slender; distal end of merus of fourth ambulatory leg almost reaching last anterolateral tooth when apposed against carapace. Remarks. It is noteworthy to note that in the original description of Guitonia , Garth & Iliffe (1992: 310) attribute a unique character to the genus: “Orbits failing to close externally at level of postorbital (first anterolateral) tooth, instead communicating by means of shallow trough or gutter with second anterolateral tooth.” Indeed, the figures ( Garth & Iliffe 1992: 312, fig. 1B, C ) show this character in G. troglophila . A reexamination of the type specimen of G. troglophila , however, shows that this is not the case, and the orbits are typical of most xanthids ( Fig. 1 F). The original descriptions and figures are therefore incorrect in this respect. The orbital structures of G. paulayi n. sp. , and G. leimomi n. sp. , are also typical of most xanthids. Distribution. Known only from the Galápagos Is.
