TYPE MATERIAL: Rhopalurus garridoi : Holotype ♀ (IES, IZACC-3.616), 1 ♂, 1 ♀, 5 subad. paratypes (IES), CUBA: Guantánamo Prov.: Baitiquirí , Guantánamo, xii.1971, O.H. Garrido.

DIAGNOSIS: Heteroctenus garridoi is most closely related to H. gibarae . The two species resemble one another, and differ from the third Cuban species, H. junceus , in their smaller size and paler coloration. Heteroctenus garridoi and H. gibarae vary from 56–86 mm in total length, whereas H. junceus varies from 64–110 mm. Heteroctenus garridoi and H. gibarae are more uniformly yellow to yellowish brown in color, with less contrast between the appendages and the carapace, mesosoma, and metasoma, whereas H. junceus varies from light brown to dark reddish brown, with the entire carapace or only the interocular surface infuscate, and the carapace, mesosoma, and metasoma (especially, segments IV and V) noticeably darker than the pedipalps and legs. Additionally, the chela is less markedly sexually dimorphic in H. garridoi and H. gibarae , because the curvature of the fixed and movable fingers of the adult male is less pronounced, resulting in a much smaller gap between them proximally, when closed (fig. 25C), and the manus of the adult female is relatively more incrassate than in H. junceus . The basal expansion of the pectines is also less pronounced in H. garridoi and H. gibarae than in H. junceus . Finally, H. garridoi and H. gibarae differ from H. junceus in the more finely granular intercarinal surfaces of the carapace and the pedipalp chela manus.

Heteroctenus garridoi appears to differ from H. gibarae primarily on the basis of color. Heteroctenus garridoi is uniformly yellow whereas H. gibarae is uniformly yellowish brown, the carapace bordered by two narrow lines forming a V-shape around the interocular surface, metasomal segments IV and V darkening to blackish brown posteriorly, and the telson reddish. As in H. junceus , the pedipalp chela manus of H. garridoi is similar in color or only slightly darker than the pedipalp femur and patella, whereas the manus of H. gibarae is darker than the femur and patella. The ventrolateral and ventrosubmedian carinae of the metasoma are infuscate in H. garridoi but immaculate in H. gibarae .

DISTRIBUTION: Heteroctenus garridoi is endemic to Guantánamo Province in southeastern Cuba (fig. 3B).

ECOLOGY: Heteroctenus garridoi inhabits semidesert habitats below 150 m in the coastal and subcoastal regions of eastern Cuba ( Teruel, 2006). The habitat and habitus are consistent with the lapidicolous ecomorphotype ( Prendini, 2001b). The species is typically found under stones, tree trunks, and inside Yucca spp. or cactus ( Ritterocereus spp.) plants ( Teruel, 2006). Heteroctenus garridoi has been collected in sympatry with the buthids Centruroides robertoi , H. junceus , Microtityus guantanamo Armas, 1984 , and the diplocentrid Cazierius gundlachii (Karsch 1880) (see Teruel, 2006).
