| Distribution | Philippine Islands (Mt. Guiting-Guiting National Park, Sibuyan Island, Romblon Island) Type locality: vine overhanging the bank of the Gaong River, at Barangay Tampayan(12.4699◦N, 122.5494◦E), collected from 50 m a.s.l., Municipality of Magdiwang, Romblon Province, Sibuyan Island, Philippines. |
| Reproduction | |
| Types | Holotype. PNM 9866 (Figs. 3A, 3B), formerly UPLB-MNH-Z-NS 4621 (CGM 988), small,but reproductively mature male (SVL 66.1 mm), collected 18 June 2017, between 0100 and 0200 hrs, by Camila Meneses and Sean Arnel Gonzales. Paratype. UPLB MNH-Z-NS 4622 (CGM 989), adult female (SVL 78.3 mm) bearing thesame locality data as the holotype, collected between 2200 and 2400 hrs, from branches ofa sapling tree overhanging the bank of Gaong River. |
| Diagnosis | Diagnosis. Luperosaurus alvarezi sp. nov. is diagnosed from congeners by possession of thefollowing combination of characters: (1) bright yellow superciliaries and circumorbitals(Fig. 4); (2) light gray iris (Fig. 4); (3) precloacofemorals 22,22 (Fig. 5B; Fig. S1); (4) five scales contacting nostrils (Figs. 6A, 6B, 6D); (5) Head length/width 1.4,1.5; (6) presence of few, enlarged, flat to convex ornamental scales on margin of anterior forelimb expansion; (7) presence of elliptical, small, and oblique auricular opening; (8) dorsal body tubercles absent; (9) ventrolateral body tubercles absent; (10) presence of few, flat, and enlarged scales on caudal edges of tail whorls; (11) longitudinal midventrals 108, 110; (12) anterior hindlimbs expansions reduced to moderate folds. The condition of five scales contacting the nostrils, head length-to-width ratio, absence of dorsal and ventrolateral body tubercles, and presence of a few flat, enlarged scales on the caudal edges of tail whorls are shared among congeners but are diagnostic for Luperosaurus alvarezi sp. nov. in combination with other characters, distinguishing it from the morphologically similar L. corfieldi and L. cumingii, with which it shares certain intermediate external similarities. Table 1 presents a summary of the distribution of diagnostic character states among Philippine Luperosaurus. (Meneses & Brown 2026) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about less than half a page) are available for collaborators and contributors. Please contact us if you need any of this material. |

| Etymology | The new species is named after authors dear friend, frequent field companionand collaborator, the late James Alvarez, who lost his life while conducting bat research inthe Philippines’ highest mountain, Mt. Apo, on December 8, 2018. We derived the specificepithet, a patronym, in the genitive singular, in recognition to Mr. Alvarez’s scientificcontributions and demonstrated personal commitment to furthering knowledge of thenatural history of Philippine chiropterans—in particular, the ecology and diversity of batsin Sibuyan Island. |
