| Diagnosis | Diagnosis: Diplolaemus vulcanus differs from the other members of the clade and by its large number of SAMB (range = 176–223, mean =196.7; D, darwinii: range 155–199, mean =180.2, z =1.31; D. bibronii: range =163–229, mean =183.2, z =0.94; D. sexcinctus: range = 157–216 mean = 186.8, z = 0.72; D. leopardinus: range =162–184, mean =173.3, z =1.9). In comparison with the other species of the group (Fig. 7, Table 2), D. vulcanus can be categorically distinguished from D. darwinii by some traits, such as SNG (range 67–82 vs 48–63), SSS (range 3–4 vs 1–2), and SNR (range 3–4 vs 1–2). Also, many traits statistically distinguish D. vulcanus (mean values of ILS = 11.67, SLS =12.28, DS =188.6, SVL =88.99 mm, HL =24.2 mm, AGD 38.37 mm, TL =16.96 mm, AL =26.03 mm, SNG =72.89, VS =192.5, SNR =3.111, HW =16.46 mm, LP =2978) form D. darwinii (mean values of ILS =9.118 z =2.58, SLS =10.12 z =2.32, DS =167 z =1.97, HL =16.78 mm z =1.8, SVL =66.82 mm z =1.79, TL =11.37 mm z =1.36, AGD =30.95 mm z =-1.03, AL =18.43 mm; z =0.9); D. bibronii (mean values of SNG =66.12 z =1.18, AL =23.96 mm z =0.87, TL =15.32 mm z =0.79, DS =179.2 z =0.73, VS =184.5 z =0. 64, SNR =2.786 z =0.63); D. sexcinctus (mean value of HW = 15.62 mm z =1.06); and D. leopardinus (mean values of DS =157.2 z =2.81, VS =169.5 z =1.88, LP 27 z =1.62, SNG =64.5 z =1.49). Head morphology of D. vulcanus is robust (Fig. S8): The circumference of the eye is broader, the scales on the head have a more forward termination, masseter muscle is over-developed in comparison to D. darwinii, D. bibronii, and D. leopardinus, and the snout is elongated and broadened in comparison to D. sexcinctus, D. darwinii, and D. bibronii. The dorsal pattern of D. vulcanus consists of four to seven brown/dark-brown bands from the shoulder to the pelvic region with black dots inside them (Fig. 6, S4, and S6). |
| Comment | |
| Etymology | Named after Latin vulcanus for Vulcan, God of fire, in reference to the volcanic environments in which most of the specimens were found; all localities where the new species was collected are volcanic lava fields. |
