The tadpoles have a body length of 14.5 - 16.4 mm and a total length of 40.8 - 44 mm. In the dorsal view, the body is ovoid and the snout if bluntly rounded. The eyes are small and are dorsolaterally directed. The nostrils are anterolaterally directed and are slightly closer to the eyes than they are to the tip of the snout. The spiracle is sinistral on the midline on the midlength of its body. The long cloacal tube is dextral. The caudal musculature is moderately robust and extends near to the tip of the tail. The fins are shallow. The caudal musculature is at the midlength of the tail and is deeper than either the ventral or dorsal fins. The dorsal fin does not extend onto the body. The mouth is ventral and at its greatest width is a little over half the width of the body. The oral disc is not notched at the margin. A single row of small papillae completely borders the edge of the oral disc and a row of larger papillae are present along the middle to the fringing row. It has a well-developed beak that has long, pointed serrations equal in length. The V-shaped lower beak is fairly robust (McCranie and Wilson 1981).
Plectrohyla dasypus can be differentiated from other frogs of the Plectrohyla genus by its spines that are by its vocal slits. These spines are blunt, short, and prepollical, whereas other Plectrohyla frogs have spines that are long, pointed, and distally curved. It can also be differentiated by the color of its spots that are only found in this species and a few individuals of P. matudai (Duellman and Campbell 1992). P. dasypus lacks a vertical rostral keel that is seen in other species of the Plectrohyla genus. In general, P. dasypus is slightly larger than the other frogs of its genus (McCranie and Wilson 1981).
This species has small, scattered black spots with have a lime-green border on a bronze dorsum (Duellman and Campbell 1992). It has a black stripe that follows the canthus above the tympanum to above the arm. The venter and hidden leg areas are dark grey, as is the toe webbing. The eyes are copper and have black reticulations. The chin is grey with a thin bronze layer. In preservative, the dorsum is dark grey with small, scattered black spots and the venter is grey. The tadpole has a creamy tan caudal musculature that has dark brown flecks lengthwise. The fins are translucent and have dark brown spots, with more spots on the dorsal fin (McCranie and Wilson 1981).
The forelimbs between individuals may vary with some paratypes having hypertrophied forelimbs while others do not. In preservative, the females have venters that are paler than males (McCranie and Wilson 1981).

The Plectrohyla and Hyla histineta groups are considered to be allopatric ecological counterparts. They share a few synapomorphies with each other: medial ramus of pterygoid that is long and articulates with the otic capsule, thick dorsal skin, fringing papillae that are continuous on the upper lip (Duellman and Campbell 1992).
The species name is the generic name of the nine-banded armadillo, Dasypus novemcinctus. The common name of the armadillo is Cusuco, which is the location where P. dasypus is found (McCranie and Wilson 1981).
