“…However, some characteristics of I. bombayensis point toward areas for possible further investigation. Icthyophis bombayensis has the largest known clutch size of any caecilian species, the >100 eggs (Bhatta, 1999) being much greater than the next largest known for other Western Ghats taxa (<40 for Icthyophis beddomei ; G. Bhatta, unpubl. data; Kupfer, Nabithabatha & Himstedt, 2004: table 5).…”

The mountainous Western Ghats are part of a biodiversity hotspot and extend for about 1600 km, lying close and subparallel to the west coast of peninsular India. The region is a centre of diversity for amphibians, and recent preliminary work on some components of both caecilian (Gymnophiona) and frog (Anura) fauna is indicative of a high degree of local endemism. We investigated diversity in mitochondrial rRNA 12S and 16S sequences for long-tailed, unstriped Ichthyophis (Amphibia: Gymnophiona: Ichthyophiidae) that potentially represent four taxonomically confused and poorly known endemic caecilian species. Data were analysed for18 individuals from along c.

“…In T. compressicauda, Exbrayat and Morel [59] have shown that the activity of the gonadotropic cells of the pituitary was correlated with that of the genital tract. In the oviparous species Ichthyophis beddomei, Bhatta [60] indicated that the size of gonadotropic cells reached its maximum before ovulation and decreased after breeding. These data are consistent with those obtained in different anuran species, which show important hormonal seasonal variations related to seasonal reproductive activity [31].…”

“…kohtaoensis is not an explosive breeder and females do not lay egg clutches immediately at the onset of the monsoon. Because caecilians practise internal fertilization via copulation (Barrio, 1969; Bhatta, 1999), mating and oviposition are temporally dissociated. The mating season of I. cf.…”

The remarkable diversity of reproductive modes, including levels of parental care that are extensive relative to those of the other major amphibian groups, makes the limbless tropical caecilians ideally suited for evolutionary reproductive studies. Here we present key life history data for the oviparous caecilian Ichthyophis cf. kohtaoensis. We used non-invasive methods to analyse reproductive traits, seasonality of breeding and characteristics of oviposition sites in the field (Mekong valley, north-eastern Thailand). A correlation was established between reproductive activity and season, indicated by the age of egg clutches found in the field. Eggs at early developmental stages were found at the beginning of the rainy season, those with well-developed embryos at the peak of the monsoon. The body condition of females guarding younger clutches was superior to that of females with older clutches, indicative of a loss of energy reserves during the period of parental care. Maternal total length correlated positively with the number of eggs as well as with the total length of newly hatched larvae. The terrestrial oviposition sites of females were located close to temporary and permanent ponds, small brooks and rivers. It is hoped that the study will, in addition to contributing to our understanding of the evolution of caecilian reproduction, provide a basis for further comparisons of reproductive strategies among amphibians and other terrestrial tetrapods.
