Hedrick's coquí
species of amphibian
Hedrick's coquí, the treehole coquí, or coquí de Hedrick (Eleutherodactylus hedricki) is a species of frog in the family Eleutherodactylidae endemic to Puerto Rico.
Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
History
E. hedricki was discovered in 1962, when finding a new species of frog seemed very improbable. It is named in honor of Hedrick J. Rivero at age 9, who declared himself assistant to his father and followed him through creeks, caves, and mountains during any time of the day or night.
Description
Its distinctive features are the pronounced constriction in the back of the head (as if the waist were in the back of the head), a shallow furrow along the middle of the back from between the eyes to near the sacral hump, and the short, rounded snout. Other distinguishing but not necessarily exclusive characteristics are: the small eyes, with narrow upper eyelids, the uniformerly granular dorsum, the pair of light, externally concave lines on the back (not too distinct in very dark animals), the blackish throat of males, and the absence of dark streaks along the sides of the snout. The basic dorsal color may be brown or dark gray, almost uniform or with obscure variegation or vermiculations of lighter gray. The males average 32.8 mm in length, while females average 34.6 mm.
The treehole coqui is a mountain-dwelling, arboreal species that rests in and calls from holes and crevices in tree trunks and branches, often as high 20 or 30 ft from ground. The call of E. hedricki is a resonant "ping, ping, ping".
Begin with the source’s own compact description: “Hedrick's coquí” is species of amphibian. The dossier treats that line as a proposition to test through Hedrick's, coquí and species, not as a finished interpretation.
Why this record matters
The phrase “species of amphibian” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 4, 2025. The linked authority identifier is Q1594106. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1962.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
