 Description of the holotype   
An adult female (SVL 20.90), with slender body; dorsal skin smooth with small dispersed warts, ventral skin smooth, discoidal fold not evident; eye 1.30 times longer than snout; tympanum small, ratio TD/EL 21%; only lower part of the tympanic annulus barely visible, tympanic membrane absent, positioned 2 mm behind orbit; head slightly wider than long (HL/HW 0.85), greatest head width between angles of jaw 38% of SVL; snout rounded from above and in profile; nares situated near tip of snout and slightly dorsolaterally directed, visible in frontal view, and also visible dorsally but not ventrally; canthus rostralis rounded; loreal region feebly concave; dentigerous processes barely visible, in frontal of the orbit of eyes in a straight outline, each with four teeth; vocal slits absent; tongue long (20% of SVL) and broadening to the end, first third attached to floor of mouth; hands moderate in size, 23% of SVL; relative lengths of adpressed fingers I <II <IV <III; finger II smaller than finger VI, finger II reaching the base of disc on finger IV when adpressed; finger III disc 1.6 times wider than distal end of adjacent phalanx; palmar tubercle low and rounded, larger than thenar tubercle; thenar tubercle low and elongate; subarticular tubercles rounded and globular; no supernumerary tubercles; palmar and plantar accessory tubercles small and rounded; no nuptial pads; no fringes on fingers; hindlimbs of moderate lengths, TL 46% of SVL; relative lengths of adpressed toes I <II <III <V <IV; when adpressed, tip of toe I reaches the last third of distal phalanx of toe II; disc of toe IV slightly expanded, 1.3 times wider than distal end of adjacent phalanx; no fringes on toes; subarticular tubercles present (one each on toes I and II, two on toes III and V, and three on toe IV), first subarticular tubercles more visible than the rest; inner metatarsal tubercle ovoid; outer metatarsal tubercles rounded, slightly pointed, and smaller than inner; tarsal ridge absent; hands and feet without webbing; finger and toe discs slightly triangular; ungual flap expanded, even, rounded; pads globular in profile (Fig. 7B).  
 Coloration of holotype in life   
Holotype (SMF 97293, Fig. 11) recorded as follows: iris light orange yellow (7) with middle area light Pratt’s rufous (71); dorsal ground color chestnut (30) with peach red (70) areas in the occipital, flanks, and lumbar region; a spectrum red (67) interorbital band, bordered posteriorly by a sepia (286) band; axilla and groin slightly pigmented with chestnut (30); limbs same as dorsum; ventral areas translucent slightly pigmented with sepia (286); ventral part of fingers and toes dark carmine (61).  
 Coloration in preservative   
Dorsal ground color burnt sienna (38) with flesh ocher (57) areas in the occipital, flanks, and lumbar region; interorbital band flesh ocher (57), groin and venter light buff (2), ventral surfaces of limbs light orange yellow (7).  
 Measurements of holotype (mm)   
SVL 20.90; HL 6.53; HW 7.68; IOD 2.21; EL 2.97; TD 0.62; FL 8.41; TL 9.51; HAL 4.79; 3FW 0.47; 3FD 0.75; 3TW 0.47; 3TD 0.65; 4TW 0.42; 4TD 0.53; BW 6.77 (for variation of the species, see Table 1).  
 Vocalization   
 The calls produced by one specimen (SMF 97658, environmental temperature 18.5 °C; 3 December 2012, 18:19 h) were analysed. The call consisted of single, short, monophasic notes that are reminiscent of a ‘whistle’ (Fig. 6). Note duration is 0.01 – 0.02 s, with an interval between calls of 2.67 – 6.02 s and a call rate of 12.32 calls/min; the low frequency was 2.38 – 3.03 kHz, the high frequency was 2.85 – 3.14 kHz, and the first harmonic contains the dominant frequency at 2.47 – 2.71 kHz.   
 Natural history   
 This species is found in the eastern Panamanian montane forest (Fund & Hogan, 2012) of the Maje mountain ranges (Fig. 1). Cloud forest in this area has vegetation consisting predominantly of trees covered with moss and a large variety of understory bromeliads (Werauhia spp. and Guzmania spp.). At night, D. majeensis sp. nov. was found 0.5 – 2.0 m above ground on tree bark in bromeliad foliage. During the daytime, individuals were found hiding between bromeliad leaves. At the top of Cerro Chucantı, males were calling during the end of the rainy season (December). The recorded male was observed calling between dry bromeliad leaves 1.5 m above ground. The diet is not known, but as with other Diasporus it is likely to eat small crickets, cockroaches, ants, and isopods (Batista, 2009).   
 Etymology   
 The species name is derived from the name of the mountain range, Maje, where the holotype was found, with the Latin suffix - ensis donating a place or locality.
