A new species of karst-adapted gekkonid lizard of the genus Cnemaspis Strauch is described from Gua Gunting and Gua Goyang in a karst region of Merapoh, Pahang, Peninsular Malaysia whose unique limestone formations are in immediate danger of being quarried. The new species differs from all other species of Cnemaspis based on its unique suite of mor-phological and color pattern characters. Its discovery underscores the unique biodiversity endemic to karst regions and adds to a growing list of karst-adapted reptiles from Peninsular Malaysia. We posit that new karst-adapted species endemic to limestone forests will continue to be discovered and these regions will harbor a significant percentage of Peninsular Malaysia's biodiversity and thusly should be conserved rather than quarried.

Tanjung Tuan is a primary spring raptor migration watchsite in Malaysia. During northbound migration, many raptors can be seen crossing the Straits of Malacca from Sumatra (Indonesia) to Peninsular Malaysia. We examined the migration magnitude, timing, and flight behavior of migratory raptors recorded based on migration counts at Tanjung Tuan in 2009 and 2010. A total of 37615 migrating raptors of 11 species and 72277 individuals of 10 species were counted in 2009 (332 hr of observation) and 2010 (465 hr), respectively. Eighty percent of bulk passage occurred in 29-38 d, with the average median passage date occurring in mid-March. Oriental Honey-buzzard (Pernis ptilorhyncus) made up 85.9 ± 2.9% of the flight, followed by Black Baza (Aviceda leuphotes, 8.7 ± 3.8%) and Chinese Goshawk (Accipiter soloensis, 3.0 ± 2.0%). The timing of the peak daily count differed among the three major migrants with highest count of Oriental Honey-buzzards occurring at 1200-1300 H, whereas for both Black Bazas and Chinese Goshawks, peak daily counts were at 1400-1600 H (when air temperatures were the highest). Most migration occurred during days when winds were from southwest and west. The difference in migration timing is believed to be associated with the species' flight behaviors, their preferred wind direction, and the availability of thermals. The height of flight for Oriental Honey-buzzards, which used both soaring and flapping flight during migration, was positively correlated with the hourly temperature (r = 0.241, P = 0.026). Results from migration counts made at Tanjung Tuan suggest that this watchsite captures a high proportion of migratory raptors (especially for Oriental Honey-buzzards) along the East Asian-Australasian flyway. Such information, together with count data collected from other watchsites, is essential for a better understanding of migratory raptors in this region and for effective conservation. © 2014 The Raptor Research Foundation, Inc.
