Abstract

Gaultheria rostrata, a new species of wintergreen endemic to Mindanao Island, Philippines, is here described and illustrated. It resembles Gaultheria bartolomei, endemic to Luzon Island, but differs by having a terrestrial habit, shorter petioles, longer pedicels, white or pale-pink corollas, coiled corolla lobes, longer anther tubules, and a longer style. The flowers of Gaultheria rostrata are unique among Asian species of Gaultheria on account of their coiled corolla lobes exposing the anthers and style at anthesis. This discovery raises the number of Gaultheria species in the Philippines to 16.

Gaultheria rostrata M.N.Tamayo, P.W.Fritsch & Medecilo, sp. nov.

This species resembles the Philippine endemic Gaultheria bartolomei (Ferreras & Argent) Kron & P.W.Fritsch but differs by having a terrestrial habit (vs epiphytic), shorter petioles (4–4.5 mm vs 5–7 mm), longer pedicels (20–35 mm vs 20–25 mm), white or pale-pink corollas (vs deep pink), corolla lobes coiled (vs reflexed), longer anther tubules (4–4.5 mm vs c.1 mm), and a longer style (10–11 mm vs c.8 mm).

Etymology. The specific epithet rostrata alludes to the morphological resemblance of the flowers of the new species to avian beaks or proboscides.

Abstract

 We describe a new species of miniaturised Platymantis (subgenus Lahatnanguri) from the Romblon Island Group (RIG), Philippines. Previously, the RIG population was treated as Platymantis pygmaeus, a forestdwelling species endemic to Luzon Island due to morphological, ecological, and acoustic similarities. We conducted phylogenetic analyses using 16S mitochondrial DNA sequences and quantified morphological variation across a statistically robust sample size to assess the distinctiveness of the RIG population. Our results recovered the RIG lineage as monophyletic with moderate support (75% bootstrap; 0.83 BPP). Phylogenetic analyses further demonstrate that Platymantis guiting, new species, is not closely related to P. pygmaeus and it is morphologically distinguished by shorter limb proportions and a stereotyped advertisement call characterised by a single-pulsed, repetitive clicking. Named after Mount Guiting-Guiting, the highest peak on Sibuyan Island, this species stands as a powerful reminder of the biogeographic subregion’s fragile and irreplaceable biodiversity. This taxonomic revision highlights the unique herpetological diversity of the RIG and reinforces the need for targeted conservation efforts in this biogeographically significant subregion.

Platymantis (Lahatnanguri) guiting, new species 

Etymology. The specific epithet guiting is derived from Mount Guiting-Guiting, the highest peak on Sibuyan (and the larger Romblon Island Group), with an elevation of 2,058 m asl. This mountain is a prominent geographical feature of the region and a biodiversity hotspot at the heart of Sibuyan Island, characterised by its unique flora and fauna (Brown & Alcala, 1974; Goodman & Ingle, 1993; Nerz et al., 1997; Lit & Eusebio, 2008; Esselstyn & Goodman, 2010; Brown et al., 2011; Davis et al., 2016; Heaney et al., 2005; Rickart et al., 2005; Siler et al., 2012, 2016; Lucañas, 2021; Tautel & Dupo, 2021; Ermilov & Corpuz-Raros, 2022a, b; Meneses et al., 2022). The name honours the ecological significance of the mountain and its role in conserving locally endemic species of herpetofauna in RIG.

Abstract

 The taxonomy of the West Pacific dromiid genus, Frodromia McLay, 1993, is revised using a suite of characters pertaining to the carapace form and armature, proportions of the ambulatory dactylus, and structures of the pereopods, thoracic sternum, male pleon, and gonopods. The identity of the poorly known type species, F. atypica (Sakai, 1936), is clarified and the species is rediagnosed and illustrated based on the single non-type dried specimen available. Frodromia reticulata (Sakai, 1974) is also rediagnosed on the basis of a series of Japanese specimens. The material identified as F. atypica by McLay (1993) from New Caledonia and the Indonesian Moluccas is here shown to belong to two new species, F. granulosa and F. caileani, respectively; with F. granulosa also reported from Vanuatu. Two other new species, F. elegans and F. iners, are described from the South China Sea and the Philippines, respectively. As a result, Frodromia is hereby classified in the subfamily Frodromiinae Števčić, 2005, which was originally established as a tribe in Sphaerodromiinae Guinot & Tavares, 2003, and which is here redefined and rediagnosed.

Abstract

Mindanao, the second-largest island in the Philippines, is a center of plant endemism shaped by its complex geology, varied topography, and high habitat heterogeneity. Continued botanical explorations in the region have led to the discovery of Begonia occidentalis, which is herein described and illustrated. It morphologically resembles B. copelandii in its persistent stipules and capsule with strongly unequal wings, but can be readily distinguished by its arachnoid petiole, ovate leaf lamina with slightly overlapping cordate base and acuminate apex, a weakly serrate margin with densely conspicuous maroon hairs, and dorsally glandular floral bracts. A comprehensive taxonomic account is presented, including detailed morphological description, geographical distribution, habitat, phenology, conservation status and a discussion on its taxonomic affinities. Furthermore, we lectotypify the name B. copelandii in accordance with the International Code of Nomenclature for algae, fungi and plants (Madrid Code).

Abstract

Recent field work in Sabah state of Malaysia in Borneo, as well as Mindanao, Negros and Siquijor Islands in the Philippines has led to the collection of crickets from the family Phalangopsidae. This allows us to review the taxonomy of Luzonogryllus Yamasaki, 1978 from the Philippines and Sabah. We also describe a new species from Mindanao: Luzonogryllus (Apterozacla) appa Tan & Alo, sp. nov. We also present new locality records for Luzonogryllus (Apterozacla) mindoroensis Gorochov, 2006 in Negros and Siquijor Islands. Lastly, we also present new material of Strophiola lugubrina (Stål, 1877) from Mindanao and Negros Islands.

[Herpetology • 2026] Luperosaurus alvarezi • A New Species of fringed Forest Gecko, Genus Luperosaurus (Squamata: Gekkonidae), from Sibuyan Island, Central Philippines

Luperosaurus alvarezi Meneses​ & Brown, 2026
Luperosaurus cumingii Gray, 1845

DOI: doi.org/10.7717/peerj.20504

Abstract 

We describe a new species of Luperosaurus based on two specimens collected on Sibuyan Island, Romblon Province, central Philippines. The new species is phenotypically similar to L. cumingii (southern Luzon), L. angliit (northern Luzon), L. corfieldi (from Panay and Negros islands), and L. macgregori (the Babuyan and Batanes island groups), but differs from these closely related congeners and all other known Luperosaurus by a combination of discrete morphological characters. Extensive molecular divergence from all closely related species for which genetic data are available supports the new species as a distinct lineage. Its distribution is geographically isolated from congeners, restricted to a permanently isolated deep-water island. The new species’ extremely limited geographic range contributes to the recognition of the remaining forests of the central Philippine Romblon Island Group as a fundamental conservation priority for the archipelago.

Luperosaurus alvarezi sp. nov.

  Diagnosis. Luperosaurus alvarezi sp. nov. is diagnosed from congeners by possession of the following 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.

Etymology: We are pleased to name the new species after our dear friend, frequent field companion and collaborator, the late James Alvarez (1991–2018), who lost his life while conducting bat research in the Philippines’ highest mountain, Mt. Apo, on December 8, 2018. We derived the specific epithet, a patronym, in the genitive singular, in recognition to Mr. Alvarez’s scientific contributions and demonstrated personal commitment to furthering knowledge of the natural history of Philippine chiropterans—in particular, the ecology and diversity of bats in Sibuyan Island.

Abstract

Medinilla calanasan is here described as a new species from Calanasan in Apayao Province in northern Luzon (Philippines). It is morphologically distinct from all other known Medinilla species in having horn-like protrusions at the base of the leaf lamina. Morphological similarities with M. clementis Merr. and M. dolichophylla Merr. suggest that M. calanasan may be a member of the M. magnifica-alliance.

Abstract  

Botanical field surveys performed in the largest terrestrial protected area in the Philippines, Samar Island Natural Park (SINP), led to the discovery of three new species of Etlingera (Zingiberaceae) herein described. Etlingera cinnabarina sp. nov. can easily be distinguished by its red orange flowers, at least among Philippine species. Etlingera funakoshii sp. nov. was first identified and recorded in the Philippines as Etlingera brevilabrum, but the absence of black patches in the ligule, absence of reddish cloudy patches in the laminae, and 1-2 flowers per flowering shoot makes it a unique species. Etlingera rigida sp. nov. is closely resembling Etlingera pilosa but unique by the sessile leaves, purplish to reddish abaxial side of the lamina and rigid young fertile bracts. Each new species is provided with a detailed description, colour plate, and information on distribution, phenology, and habitat. Etlingera cinnabarina matches the criteria of the IUCN red list as Endangered (EN), whereas E. funakoshii and E. rigida as Critically Endangered (CN), since all three species have narrow distributions and threats in their respective habitats. A key to the Etlingera of Samar Island is also provided.

Etlingera funakoshii Docot, sp. nov. 

Similar to Etlingera brevilabrum (Valeton) R.M.Sm. but differing by the glabrous ligule with black patches (vs scabrid without black patches); narrowly ovate lamina without reddish cloudy patches (vs oblong obovate with reddish cloudy patches); 1–2 flowers per flowering shoot (vs 1–6); mid pink corolla lobes (vs red); ecristate anther (vs 3 mm long anther crest); and dark purple stigma (vs dark red or white)  

Etymology. The first author named this species in honour of Dr. Hidenobu Funakoshi, who first saw and documented the species in the type locality. Since the early 2000’s, Dr. Funakoshi continues to share his interest in studying Philippine gingers up to the writing of this paper.

 Etlingera rigida Docot, sp. nov. 

 

Similar to Etlingera pilosa A.D.Poulsen & Docot but differing by the red and truncate apex of the ligule (vs greenish brown and rounded); sessile leaves (vs petiolate); red to greenish red abaxial side of the lamina (vs light green); rigid young fertile bracts (vs soft); pubescent dorsal side of the anther (vs glabrous); and fruit with few small warts near the apex when mature (vs prominently carinated). 

 

Etymology. The specific epithet refers to the rigid bracts.

Abstract

A new species, Begonia matillanoae, is here described and illustrated from Malampaya Sound Protected Landscape and Seascape, Palawan Island, Philippines. It closely resembles Begonia cabanillasii but is distinct in having an ovate leaf with irregularly lobed margin, an acute leaf apex, and a 5-tepalled pistillate flower with the larger wing flat to shallowly cucullate. Begonia matillanoae is the latest addition to the Palawan begonias bearing a conspicuously 5-winged ovary. Based on IUCN guidelines, we here propose a  Critically Endangered (CR) conservation designation for this species. A revised key to Palawan Begonia sect. Baryandra bearing five or six conspicuous ovary wings is also provided.

Begonia matillanoae resembles B. cabanillasii in having white-pilose indumentum on its petioles, leaves and peduncles, a 4-tepalled staminate flower, and a conspicuously 5-winged ovary. However, it differs in having an ovate leaf shape (vs suborbicular) with shallow acutely lobed margin (vs crenate), an acute leaf apex (vs acute, obtuse or rounded), and a 5-tepalled (vs 4-tepalled) pistillate flower with largest wing flat to shallowly cucullate (vs distinctly cucullate).

Pachyrhynchus analynae Obrial, Agbas, Pajota & Medina sp. nov.

Diagnosis: Pachyrhynchus analynae sp. nov. belongs to the P. speciosus species group. In general appearance, this novel species conspicuously resembles a cross between P. miltoni Cabras & Rukmane, 2016, from Marilog, Davao City, and P. cabrasae Rukmane, 2016, from Mt. Kalatungan, Bukidnon. It exhibits a combination of scaly maculations found in both congeners: the longitudinal scaly bands at pronotum which resembles P. miltoni, while reticulate scales at elytra resembles P. cabrasae. However, P. analynae sp. nov. differs with P. miltonibased on the following characteristics: amygdaloid elytral shape, narrower in profile, and tapers apically; elytra bears reticulate net-like maculations that merge and sparsely covered with setae from the apical declivity towards the apex (vs stouter elytra with minute setae only along the lateral margin; with open-and closed-banded variations, with three contiguous scaly bands, with open-banded variation that retains the three scaly bands in P. miltoni).

 Variability of Pachyrhynchus analynae Obrial, Agbas, Pajota & Medina sp. nov.:
A) open-banded, holotype male, B) filled-banded, paratype male
C) unfilled-banded, paratype, female, D) filled-banded, paratype female.
