Leptobrachium chapaense ( Bourret, 1937)

Specimens matching the description ( Bourret, 1942) and redescription ( Lathrop et al., 1998) of L. chapaense were found on Mt. Tay Con Linh II. Adults with white on the top quarter of the iris, metamorphs with offwhite to yellow on the top quarter of the iris. Dorsum brown, a black line running from the snout to the eye, continuing posterior to the eye, half­way down the supratympanic fold. Red and black marbling on inner thighs (flash colors). White network on brown for entire venter (throat to calves). Tips of toes white.

Adults were found on the forest floor at 1400 m. Tadpoles and metamorphs were abundant in almost every waterway; metamorphs especially in deep pools. Over the course of 21 days of pitfall trapping on Mt. Tay Con Linh II, 13 juvenile L. chapaense were collected for only five consecutive days (17–21 May). This suggests that in this region there is a narrow window in which juvenile L. chapaense disperse from the streams to the forests.

Leptobrachium chapaense is known from China: central and southern Yunnan ; northern Vietnam: Lao Cai , Vinh Phu, Cao Bang,

Thanh Hoa, and Ha Tinh Provinces; Laos: Bokeo Province; Thailand: Chiang Mai Province; Myanmar: Karin region; and India: State of Meghalaya ( Dubois and Ohler, 1998; Lathrop et al., 1998; Ziegler, 2002).
