Hamidy on 26 April 2017 at 19:00. Etymology. We dedicate the specific name to late Drs. Boeadi. He is an Indonesian herpetologist, mammalogist, naturalist, and former staff member of the Museum Zoologicum Bogoriense. He collected many samples of fauna that were deposited in MZB, and his contributions to the advancement of zoological sciences in Indonesia have left a lasting impact. Diagnosis. The new species is placed in the genus Rhacophorus based on the possession of these following characters: presence of intercalary cartilage between terminal and penultimate phalanges of digits, terminal phalanges of finger and toes Y-shaped, tips of the digits expanded into large disks bearing circum-marginal grooves, webbed fingers, horizontal pupil, and the skin not co-ossified to scull (Duellman and Trueb 1986; Liem 1970; Brown and Alcala 1994; Malkmus et al. 2002; Inger and Stuebing 2005). Rhacophorus boeadii sp. nov. can be distinguished from its congeners by the combination of the following characters: medium size (SVL adult males [n=12] 40.4–44.6 mm, adult females [n=9] 48.1–54.2 mm); snout sharply pointed in males, sloping; canthus rostralis sharp; vomerine teeth present in two oblique series; tympanum visible; supra tympanic fold thick and conspicuous; nuptial pad on male presence; yellowish gland on the shoulder; dark blotching on ventral surface of chin and chest, lateral side of forelimbs, and hind-limbs; dorsal skin coarsely granular with white-tipped keratinized asperities; flank with white blotched pattern; dermal flaps on limbs absent, only weak crenate fringes present on the postaxial side of the distal half of lower arm; and heel without dermal appendage. Description of holotype (in mm). Body size medium (SVL 42.0 mm); head longer (HL 13.4; 36.6 % SVL) than wide (HW 12.0; 33.1 % SVL); snout pointed in dorsal view, projecting over the lower jaw in lateral view, canthus rostralis sharp and distinct, curved in dorsal view; lore concave; nostril slightly protuberant, positioned dorsolaterally without a flap of skin, closer to snout than to eye; internarial distance (IND 3.1; 7.5 % SVL) smaller than interorbital distance (IOD 4.9; 11.6 % SVL); interorbital distance slightly wider than upper eyelid width (UEW 4.2; 9.9 % SVL); pineal spot absent; pupil elliptical, horizontal; eye large (ED 6.2; 14.8 % SVL) about five and one-half times tympanum-eye length (TEL 1.12; 2.7 % SVL); tympanum distinct, circular, about one-third of eye diameter (TD 2.0; 4.9 % SVL) and twice tympanum-eye length; supra tympanic fold distinct, elevated from posterior edge of eye to above arm insertion; choanae circular; vomerine teeth present in two oblique series; vocal sac median, subgular; vocal slit present on both sides near corner of mouth; tongue lanceolate, attached anteriorly and deeply notched posteriorly. Forelimbs slender, lower arm and hand length (LAL 22.1; 52.6 % SVL), relative finger lengths I
