|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Common Names||E: Five-banded Bent-toed Gecko|
|Synonym||Cyrtodactylus limajalur DAVIS, BAUER, JACKMAN, NASHRIQ & DAS 2019|
|Distribution||East Malaysia (Borneo: Sarawak)|
Type locality: near Kampung Tubih Mawang, Serian, Sarawak, East Malaysia. (01°17'47.62"N; 110°26'33.00"E; 88 m elevation; WGS 1984)
|Types||Holotype: CAS 262848, adult male (Fig. 5 in Davis et al. 2019), collected by Izneil Nashriq and Hayden Davis on August 06, 2017 at 20:00–22:00 hrs (Fig. 1).|
Paratypes. Paratypes (CAS 262846; CAS 262847; and CAS262849) (Fig. 5) have the same collection data as the holotype.
|Diagnosis||Diagnosis. Cyrtodactylus limajalur sp. nov. can be differentiated from all other species of Cyrtodactylus by the combination of the following characters: maximum SVL of at least 94 mm; 10–12 supralabials; 9–11 infralabials; weak tuberculation on body; no tubercles on ventral surface of forelimbs, gular region, or ventrolateral folds; 34–38 paravertebral tubercles; 11–13 longitudinal tubercle rows; 33–42 ventral scales; 19–22 subdigital lamellae on fourth toe; 5–6 enlarged femoral scales; no femoral pores; 7–8 precloacal pores; precloacal pit in males; enlarged median row of transverse scales; 5 dark dorsal body bands; body bands more than two times the width of interspaces; rostral chevron just posterior to orbitals; no white line edging the body bands and nuchal loop; and no scattered white tubercles on dorsum. These characters are scored across all currently recorded Bornean Cyrtodactylus species in Table 4 in Davis et al. 2019: 344.|
Comparison. Cyrtodactylus limajalur sp. nov. differs from all its Bornean congeners by one or more morphological characteristics. The new species is distinguished from C. baluensis by having a distinct banding pattern as opposed to bands and blotches; it is distinguished from C. cavernicolus by having a lower number of ventral scales (33–42 versus 51–58), enlarged subcaudals, and a precloacal pit as opposed to a precloacal groove; it is distinguished from C. consobrinus by having a smaller adult maximum SVL (94 mm versus 125 mm), and no white reticulated pattern on occiput; it is distinguished from C. ingeri by having a precloacal pit as opposed to no depression, 5–6 enlarged femoral scales as opposed to none, and a distinct banding pattern as opposed to bands and blotches; it is distinguished from C. malayanus by having no tubercles on the upper arm, and a lower number of ventral scales (33–42 versus 58–62); it is distinguished from C. matsuii by having enlarged subcaudals, 5–6 enlarged femoral scales as opposed to none, and a smaller maximum SVL (94 mm versus 105 mm); it is distinguished from C. pubisulcus by having enlarged subcaudals, 5–6 enlarged femoral scales as opposed to none, and a precloacal pit as opposed to a precloacal groove; and it is distinguished from C. yoshii by having no tubercles on the upper arm, a lower number of ventral scales (33–42 versus 50–58), a lower number of subdigital lamellae (19–22 versus 25–30), and 5–6 enlarged femoral scales as opposed to none.
|Comment||Sympatry: Cyrtodactylus consobrinus and C. pubisulcus. However, C. consobrinus was seen almost exclusively on large tree trunks and C. pubisulcus was only found on low-lying vegetation, indicating that they may not be syntopic with C. limajalur sp. nov.|
|Etymology||The specific epithet limajalur is in reference to the banding pattern of the species. “Lima jalur” loosely translated from Malay is five-banded. Cyrtodactylus limajalur sp. nov. has a very distinct banding pattern that is consistently comprised of five bands. This species is the first Bornean Cyrtodactylus species that displays a consistent banding pattern, without blotches or other markings.|
