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).
