In life, their dorsal region is a lime green with subtle large yellow spots (cream colored when preserved) underneath a layer of fine dark brown specks. Ventral region is transparent, leaving the pericardium (ranging from translucent to white) and white bones visible. The eyes feature yellow irises covered in brown flecks. Sometimes an incomplete reddish brown ring circumscribes the pupils (Castroviejo-Fisher et al. 2011).
Hyalinobatrachium cappellei was previously thought to be four different species, H. cappellei, H. crurifasciatum, H. eccentricum, and H. ignioculus because of variation in coloration of the body and iris. However, molecular evidence showed that they are genetically indistinct, and thus they were combined into the single species of H. cappellei. For a more detailed variation, please see Castroviejo-Fisher et al. 2011.

Life History, Abundance, Activity, and Special Behaviors
The breeding season occurs during the wet season with males performing calling activity from November to April. Males call from the upper side of leaves that are 1 - 5 m above water and will call while guarding existing laid clutches (Castroviejo-Fisher et al. 2011). The advertisement call is characterized as a ‘peeeep’ sound that lasts an average of 0.319 seconds, and the courtship call is characterized as ‘peeeep…fîîî’ lasting an average of 1.077 seconds. Calling activity peaks in the middle of the night (Noronha and Rodrigues 2018).
During courtship, the male calls to the female and waits to be approached, relying on touch to signal amplexus. The entire process from courtship to oviposition lasts eight hours (Noronha and Rodrigues 2018).
Females are oviparous and deposit clutches on the underside of leaves that hang above streams. Eggs hatch as tadpoles that drop into the water below. The number of eggs per clutch ranges from 4 - 32, with an average of 17.2 eggs (Noronha and Rodrigues 2018).
Males perform parental care through egg attendance, often staying close to clutches during the day and covering the eggs with their body at night, using ventral contact to support clutch hydration. Predation on clutches by cockroaches, moths, bush crickets, and ants has been observed (Noronha and Rodrigues 2018).

General habitat alteration and loss
Based on coloration of the eye and body, H. cappellei was previously thought to be four different species: H. cappellei, H. crurifasciatum, H. eccentricum, and H. ignioculus. However, Maximum Likelihood and Bayesian Inference on 16S mtDNA indicate they should be collapsed into one species, H. cappellei. Based on this same molecular analysis, H. cappellei is sister to the clade composed of H. iaspidiense and H. tricolor (Castroviejo-Fisher et al. 2011). This is supported by Guayasamin et al. (2012), who used Maximum Likelihood and Bayesian Inference of 12S, 16S, and ND1 mtDNA and c-myc exon 2, Rag1, and POMC nDNA, but did not cover all the same species in their analyses.
The species epithet, “cappellei” is in honor of Dr. H. van Cappelle, the geologist who organized the expedition in which the species was first collected by science in the lower Nickeri region of Suriname. The species was originally named "Hylella Cappellei" (Van Lidth de Jeude 1904).
