Common NamesE: Northern Beaked Gecko 
SynonymRhynchoedura sexapora PEPPER, DOUGHTY, HUTCHINSON & KEOGH 2011
Rhyncoedura sexapora — HEINICKE et al. 2023 (in error) 
DistributionAustralia (Western Australia: Kimberley region)

Type locality: El Questro Station, WA (-16.01861°S, 128.00389°E).  
Reproductionoviparous (not imputed, fide Zimin et al. 2022) 
TypesHolotype: WAM R170241 (formerly AMS R139904) (male) 
DiagnosisDiagnosis: Morphologically distinguished from congeners by six (occasionally four) slightly enlarged round pre-anal pores in a shallow ‘V’ pointing anteriorly (Fig. 5b) and dorsal scales moderately gabled, ventrals slightly larger than dorsal scales (rather than all scales flat and subequal). Further distinguished from R. mentalis sp. nov. by having a single mental scale and cloacal spurs formed by a single enlarged scale. Dorsal pattern differs from other species (except R. mentalis sp. nov.) by having a brown background color darker and with smaller pale spots (Fig. 4c, Supplementary Fig. 6, in PEPPER et al. 2011). 
Etymologysexapora is derived from the Latin sex (six) and porus (pore), referring to the condition of the pre-anal pores. Used as an adjective: ‘six-pored’.
