This species appears to be a specific ectoparasite of Iguanidae lizards (see Table 2 ). Geckobiella javieri was described originally based on male and immature specimens. One of us (RP-L) visited the Acarological Collection of IES but unfortunately the type series could not be located. However, three females were recovered from a specimen of Cyclura nubila collected from Cuba and deposited in the Herpetological Collection of IES (12729). The general morphology of these specimens is consistent with that of females of Hirstiella parasitic on Iguanidae (= Geckobiella sensu nov. in this study). Based on the character matrix (Appendix 2), G. javieri and G. diolii share all character states (except the setal form of dorsal idiosomal setae h1 ). Additional differences between these species are found in the smaller size of G. javieri , in particular in the size of some structures such as the prodorsal shield length and width 181 x 189 (versus 198 x 226 in G. diolii ) ( Fig. 2 F–G), width between setal pair sci on prodorsal shield (WSCI) 112 (versus 125 in G. diolii ), leg lengths (excluding ambulacrum) from leg I to IV respectively 373, 292, 310 and 362 (versus 463, 360, 369 and 383 in G. diolii ), and solenidion ω 1 and ω 2 of tarsus I length 27 and 45 respectively (39 and 53 in G. diolii ). In one specimen (CNAC007046) one seta vi was positioned outside the prodorsal shield.
