First record of the Mourning Gecko, Lepidodactylus lugubris (Duméril & Bibron), from the Turks and Caicos Islands with additional observations from the Bahamas

“…Herein, we report the first record of L. lugubris from the Turks and Caicos Islands and two additional locations in the Bahamas situated ~210 km ESE and ~344 km SE of the location reported by Krysko & MacKenzie-Krysko (2016). We believe that our new records of L. lugubris are clone type A based on external morphology (Yamashiro et al 2000;Hoogmoed & Avila-Pires 2015;Ineich 2015;Griffing et al 2018) and that is consistent with individuals reported from nearby locations (Krysko & MacKenzie-Krysko 2016; Bosch & Paez 2017).…”

Sexual characteristics and spermatogenesis in males of the parthenogenetic gecko Lepidodactylus lugubris (Reptilia, Gekkonidae)

“…Triploid clones originated through backcrossing of the parthenogenetic L. lugubris with males of the parental species. Both diploid and triploid clones are now widespread throughout the distribution area of L. lugubris (Moritz et al, 1993;Yamashiro et al, 2000).…”

“…Furthermore, most of the phenotypic males are hybrids between the ancestral sexual species and L. lugubris, which lack functional gonads and associated organs, thus indicating sterility on a very basic level (Ineich, 1988;Radtkey et al, 1995;Ota et al, 1995). However, rare males were also reported from other locations (Hawaiian Islands, Mariana Islands, Ryukyu Archipelago) where no other bisexual species of Lepidodactylus occurs (Brown and Murphy-Walker, 1996;Yamashiro and Ota, 1998;Yamashiro et al, 2000). It is assumed that a hormonal sex inversion causes the emergence of such males (Darevsky et al, 1985, for parthenogenetic lacertids).…”

Molecular discrimination and phylogeographic patterns of clones of the parthenogenetic gecko Lepidodactylus lugubris in the Japanese Archipelago

“…Geckos include relatively large number of parthenogenetic species such as Lepidodactylus lugubris , Hemidactylus garnotii and Indotyphlops braminus , and several studies have revealed their clonal diversity and phylogenetic relationship with sexually reproductive relatives (Ineich, , ; Kearney, Blackett, Strasburg, & Moritz, ; Kluge & Eckardt, ; Moritz, Case, Bolger, & Donnellan, ; Radtkey et al, ; Roberts, Vo, Fujita, Moritz, & Kearney, ; Volobouev, Pasteur, Ineich, & Dutrillaux, ; Yamashiro, Toda, & Ota, ). However, such clonal polymorphisms have been still unclear in geckos because no information is available regarding the modern genetic approaches of these clones.…”

“…The lectotype of this species was derived from Tahiti, French Polynesia (Torres‐Carvajal, ). This species is all females and reproduces parthenogenetically, consisting of diploid (2n = 2x = 44) and triploid (2n = 3x = 66) clones (Ineich, ; Moritz & King, ; Volobouev et al, ; Yamashiro et al, ). Each strain includes a number of genetically divergent clones, some of which were identifiable based on the dorsal color marking patterns and protein polymorphism (Ineich, , ; Moritz et al, ; Yamashiro et al, ).…”
