DiagnosisDiagnosis: H. granchii can be distinguished from the following species:
H. arnoldi has a conspicuous dorsal colour pattern of broad, dark, transverse bands. Between the base of the 1st and 5th toe there is a marked roundish smooth enlarged scale surrounded by small granular scales (Lanza, 1978).
• H. barodanus Boulenger, 1901 differs from H. granchii in having more infrala- bial scales (8 vs. 7 in H. granchii) and relatively flat dorsal tubercles without distinct keels.
• H. macropholis Boulenger, 1896 differs in the arrangement of the scales around the nostril. First supralabial in H. macropholis is in contact with the nostril unlike in H. granchii, where rostral is touching the outermost nasal and separates the nos- tril from the first supralabial. H. macropholis has also lower number of infralabials (8 vs. 6-7 in H. granchii).
• H. taylori Parker, 1932 has a higher number of lamellae under the 2nd finger (9 vs. 7-8 in H. granchii) and under the 1st toe (8 vs. 7 in H. granchii). It also has more dilated digits than H. granchii (see Lanza 1978, Fig. 19 on p. 262) and ante- rior chin shields in contact only with the first infralabial (1st and 2nd infralabials in H. granchii, at least on one side). The most remarkable difference, which unfortu- nately can not be compared in the newly reported specimen, is the shape of unre- generated tail. The tail of H. taylori has a basal constriction and is considerably wide in comparison with that of H. granchii.
• H. yerburii pauciporosus has more supralabials than H. granchii (11 vs. 9-10) and the nostril is in contact with the first supralabial. [from Šmíd et al. 2014] 
Comment 
EtymologyNamed after E. Granchi, a friend of Lanza and technician of the Istituto di Zoologia of the University of Florence, “one of the best Italian taxidermists and field naturalists, irreplaceable companion and collaborator during my research in East Africa.”
