Diagnosis | DIAGNOSIS (n=2): A small highland species of Arthrosaura readily distinguished from its nearest geographic neighbor (A. testigensis, Los Testigos range, east of Auyantepui) in having three (vs. four) supraoculars and in having a pale dorsolateral line on each side and an unmarked venter (vs. four narrow yellowish stripes on dorsum and brown spots on venter). A presumably unnamed species from the Chimantá massif (southeast of Auyantepui) evidently differs from A. montigena in having a dark brown middorsal stripe (Gorzula and Señaris, 1999: photo 89). Arthrosaura montigena shares many characteristics of A. versteegii (French Guiana to extreme eastern Venezuela, as redefined by Hoogmoed and Avila-Pires 1992: 470–477) but differs in having a more complete pale dorsolateral line and in not having the ventral or ventrolateral scales sharply demarcated by a zone of small scales.
