The patterns of geographical distribution of eublepharid lizards show that
they are relicts of formerly diverse circumtropical group of lizards.
According to classification of Kluge (1987) they are considered as
superfamily Eublepharoidae Boulenger, 1883. The recent forms (about 20
species) are distributed from equator (Holodactylus africanus, H. cornii,
Aeluroscalabotes felinus) to 38 of north latitude (Eublepharis turcmenicus,
Coleonyx variegatus) in America, Africa, and Asia (Wermuth, 1965; Scherbak
and Golubev, 1986; Grismer, 1988).
Asiatic eublepharids belong to three genera:
Aeluroscalabotes Boulenger, 1925; Goniurosaurus Barbour, 1968 and Eublepharis
Gray, 1827. The most species of these genera are rare lizards with very
limited distribution range. They are objects of our program of reproduction
and captive breeding (Kaverkin et al. 1994; Kaverkin and Orlov, in press).
One of the rarest species of Eublepharis
genus, Eublepharis turcmenicus, inhabits Kopet Dag mountains in the southern
Turkmenistan and northern Iran. In 1994 we succeeded to have successful
captive breeding of this species. The group of captive breeding includes 3
individuals (2 males and 1 female) which were kept from 1990. In 1992-1993
preparing E. turcmenicus to reproduction we used the methods traditional for
E. macularius captive breeding that gave no positive results and we have
received no fertile copulation. In 1994 we used prolonged hibernation
(3 months) with relatively low temperatures of 13-14°C. The geckos were
brought out the hibernation in March and were kept separately for a month.

Then the males by turns were placed to the cage with female. During night
time a number of copulations were noted. Diurnal temperature was 25-26°C.
The more warm place with substratic temperature 35-37°C was organized in the
cage. The night temperature fall to 20-23°C.
Two eggs were laid
June 5, they were buried to sandy substrate on the depth of 8 cm. One of
these two eggs was lost during its incubation; after 57 days of incubation
under 27°C the newborn female was hatched from the second egg. Its length
with tail was 83.5 mm.
The food of newborn lizard includes small
crickets and Galleria melonella with addition of vitamins (Osteoform,
Reptal, Reptovit). In the age of 18 month, after hibernation the young
female was brought to the male. It shows the clear indications of gestation
now. The mating behavior is very similar with E. macularius, we also noted
the vocal communications (the low twittering) of male and female before the
copulation.
We would like to express our deep gratitude
to N.B. Ananjeva, I.S. Darevsky (Zoological Institute, St. Petersburg,
Russian Academy of Sciences) for their consultations, S.M. Shammakov
(Institute of Zoology, Turkmenian Academy of Sciences), B.S. Tuniyev
(Caucasian State Biosphere Nature Reserve), and S.V. Kudryavtsev (Moscow Zoo)
for their help in providing of this materials. |
