Fig. 9: Habitat of Gekko scientiadventitra sp. n. near the type locality. Phot. T. Ziegler Apart from the voucher material of our type series no further sightings of Gekko scientiadventura sp. n. were made, with the exception of a mass egg-laying site in a dark, manifold rock crevice system at the type locality. Fig. 10 shows this site (in about m height) at the be- ginning of the rainy season (end of August) in 2001. The four geckos cited under "Other material" originate from these eggs; they hatched in September/October 2001 which correlated with the beginning rains. One year later, in August 2003, we found two glued eggs just at this mass egg-laying site. In addition, two further communal egg-laying places were found in this cave system which seemed to be used also already since a longer period; they contained, however, much less eggs and were situated much higher (ca. 5 m high). On August 30, 2003, we measured at the lower egg- laying site, at h, a relative humidity of 85% and a temperature of °C. At h the same day the temperature was °C and the relative humidity had. Fig. 10: Mass egg-laying site of Gekko scientiadven/ura sp. n. in a karst rock crevice at the type locality. Phot. T. Ziegler increased to 93% (with a recorded minimum of 70% be- tween and h). In the primary forest, outside the rock crevice system, we measured with a minimum- maximum thermometer on August 28, 2001 °C and one day later °C. For further (long- term) climatic data from this area see HERRMANN et al. (2002). One of the authors (TZ) was able to record some behav- ioural and autecological observations of the captive- raised geckos: The growling calls of Gekko scientiad- ventura sp. n. were mostly uttered during dawn and night, but could also be heard in summer afternoons ( 22-26 July, 2
