CommentSynonymy: Leiolopisma rhomboidale is probably synonymous to Carlia rhomboidalis. However, the former is listed by Barbour (1912: 187) to occur on “Papua New Guinea (Dutch)”, so Barbour’s rhomboidale may also represent a different species.

Carlia rubrigularis and C. rhomboidalis can be distinguished from all other Carlia in having the interparietal scale fused with the frontoparietal (Ingram & Covacevich 1989; Hoskin & Couper 2012). Carlia rubrigularis was split from C. rhomboidalis in 1989 on the basis of colouration, particularly of breeding males (Ingram & Covacevich 1989). In C. rhomboidalis the labials and underside of the head are blue and the throat is red (Fig. 1A), whereas in C. rubrigularis the entire lower surfaces of the head (termed here the ‘chin’) and throat are red (Fig. 1B). This colour difference in breeding males was deemed probably sufficient to confer breeding isolation should the species come into contact (Ingram & Covacevich 1989). Indeed, lab-tests of female choice have detected prezygotic isolation between these two species (Dolman 2008). Ingram & Covacevich (1989) concluded that the two species were morphologically indistinguishable other than for chin colour; however, Dolman (2008) also found subtle differences in relative limb length and head width (Hoskin 2014).
