Barilius papillatus
Day 1869

Abstract
Opsarius geminus, a new species of danionid fish is described from the Krishna River, Western Ghats, India. It can be distinguished from its congeners in the Western Ghats by possessing a combination of the following characters: unique colour pattern consisting of 9–11 blue bars that are 2–3 scales wide; 46–51 lateral-line scales; 20–23 pre-dorsal scales; barbels absent; length of last dorsal-fin ray almost equal to, or greater than length of first dorsal-fin ray; 7 ½–8½ dorsal-fin branched rays and 10½–11½ anal-fin branched rays. Barilius papillatus Day 1869, currently a synonym of Opsarius barna (Hamilton, 1822) is redescribed, based on the syntype and fresh specimens, and a lectotype is designated to fix its identity. Opsarius papillatus can be diagnosed from all its congeners in India, by possessing a combination of the following characters: colour pattern consisting of 7–9 blue bars that are 1–2 scales wide; 39–41 lateral-line scales; 15–18 pre-dorsal scales; barbels absent; length of last dorsal-fin ray shorter than length of first dorsal-fin ray; 7½ dorsal-fin branched rays and 10½ anal-fin branched rays.

[Herpetology • 2026] Gegeneophis chandgadi • Exploring Cryptic Diversity in Gegeneophis Peters (Gymnophiona: Grandisoniidae) with A Novel Species from the northern Western Ghats, Maharashtra, India

 

Gegeneophis chandgadi
Shikalgar, Patil, Adhav, Kulkarni, Hiragond, Gramapurohit, Tripathy & Dinesh, 2026

Records of the Zoological Survey of India. 126(3); 

Abstract
A new species of annulocylix caecilian is described from the genus Gegeneophis based on distinct genetic and morphological features. The species is having both primary and secondary annuli, wherein secondary annuli are concentrated at the posterior half of the body. Molecular analysis reveals that the new species is sister to an unknown lineage from Amboli and Gegeneophis mhadeiensis from the near proximity phylogenetically. Molecular phylogeny suggests the possibility of four other new lineages from the northern Western Ghats. The findings are discussed in the light of cryptic diversity of these limbless amphibians and the need for systematic studies to describe them.

Keywords: Amphibians, annulocylix caecilian, homestead areas, tailless caecilian



Gegeneophis chandgadi sp. nov.

Etymology: The species is named after the ‘Chandgadi language’, which is a distinct dialect of the language Marathi, predominantly spoken in and around the type locality Chandgad, Kolhapur, Maharashtra, India. The species epithet ‘chandgadi’ is treated as a noun in apposition to the generic name.

[Mammalogy • 2026] Rhinolophus indorouxii • Resolving Taxonomic Ambiguity: A New cryptic Rufous Horseshoe Bat (Chiroptera: Rhinolophidae: Rhinolophus) from southern India

 
 Rhinolophus indorouxii  
Raman, Garg & Chattopadhyay, 2026
 

Abstract
Bats are the second largest group of mammals with high cryptic diversity. In this study, we describe the previously identified sibling species Rhinolophus indorouxii of the endemic rufous horseshoe bat Rhinolophus rouxii from Southern India. The species was discovered based on acoustic diversity and mitochondrial cytochrome b gene sequencing–based genetic distance metric and phylogenetic affinity. However, no detailed morphological description was available. We address this lacuna by presenting with a detailed morphological description along with acoustic and genetic (cytochrome oxidase I barcoding gene) data and identify species specific characters for future studies. This is an important step in recognizing the species diversity of Southern India, which is home to one of the global biodiversity hotspots.

[Botany • 2026] Selaginella jobii (Selaginellaceae) • A New Species from the southern Western Ghats in Kerala, India

 

Selaginella jobii Alen Alex, Abhilash, Gayathri, Sojan, V. Suresh & Leeja,

in Alen, Abhilash, Gayathri, Arya, Kumar, Sojan, Suresh, Antony et Leeja, 2026.

 Abstract
Selaginella jobii Alen Alex, Abhilash, Gayathri, Sojan, V. Suresh & Leeja, sp. nova (Selaginellaceae) is described as a new lycophyte species from the southern Western Ghats in Kerala, India. It morphologically resembles S. tenera, but can be distinguished by its small habit, basal rhizophores, median leaf traits, lack of vegetative buds and tapering strobili. The taxonomic delimitation is strongly supported by multivariate morphometric analysis (PCA) of macro- and micromorphological traits. Molecular phylogenetic analysis based on the rbcL gene places S. jobii as a sister to S. miniatospora. Growing on shaded laterite habitats in Palakkad, the species has an Area of Occupancy of less than 10 km2. Consequently, it is preliminarily assessed as Critically Endangered (CR) following the IUCN criteria.

Selaginella jobii (from the holotype).
— A: Habit. — B: Rhizophore. — C: Stem. — D: Axillary leaf. — E: Lateral leaf. — F: Median leaf. — G: Strobili, dorsal view. — H: Strobili, ventral view. — I: Ventral sporophyll with megasporangium. — J: Ventral sporophyll with microsporangium. — K: Dorsal sporophyll with microsporangium.

Selaginella jobii Alen Alex, Abhilash, Gayathri, Sojan, V. Suresh & Leeja, sp. nova  

Etymology. The specific epithet jobii honours Dr Joseph Job, retired Associate Professor of Botany, St. Berchmans College, Changanassery, Kerala, India. An exemplary educator, Dr Job inspired numerous students, including the first author, to pursue science.

Diagnosis. Selaginella jobii is morphologically similar to S. tenera and S. miniatospora, but can be distinguished by its lean, non-spreading habit with exclusively basal rhizophores, tapering strobili featuring a distinct apical microsporangiate zone, and regular verrucate ornamentation on the megaspores. A comprehensive morphological comparison of these taxa is provided in Table 1.

[Entomology • 2025] Lyriothemis abrahami • A New Species of Lyriothemis Brauer, 1868 (Odonata: Libellulidae) from the Western Ghats of Peninsular India

 

Lyriothemis abrahami  Sadasivan, Jose, Nair & Palot, 

in Sadasivan, Jose, Palot, Sudheer, Augustine, Kochunarayanan, Nair et George, 2025. 

Abstract
A new species of phytotelma-breeding dragonfly, Lyriothemis abrahami sp. nov., is described from the Western Ghats of Peninsular India. The new taxon was previously misidentified as L. flava Oguma, 1915 (= L. tricolor Ris, 1916). In contrast to L. flava, the new species is sexually dimorphic, with males easily identified based on the characteristic shape of the hamules. Females are identified by their jet black and yellow colour with triangular yellow streaks on the dorsum of the abdomen and the distinct triangular shape of the vulvar lamina. Photographs of mature adults, tenerals, hamules, illustrations of vesica seminalis, vulvar lamina, and a key to Lyriothemis of the Indian subcontinent are provided.

(B–E, reared from the larvae collected in Pooyamkutty, Ernakulam District, Kerala)

Lyriothemis abrahami Sadasivan, Jose, Nair & Palot, sp. nov.

Diagnosis. Males of Lyriothemis abrahami sp. nov. are identified by the combination of the following characters: two short oval paradorsal streaks on the mesepisternum not extending halfway up the thorax towards the alar sinus; anterolateral yellow thoracic band as broad as or narrower than the black area just posterior to it; in anteroventral view hamule trapezoid, higher than wide; hamular inferolateral angle right-angled and well-defined, medial border with a distinct insinuation at the junction of its inferior and middle third, inferior border straight. The elongated shape of the hamule is a distinct characteristic of the new taxon. Sexual dimorphism is strongly exhibited in L. abrahami sp. nov., with the females identified by their jet-black and yellow colour with characteristic triangular yellow streaks on the dorsum of the abdomen and the distinct triangular shape of the vulvar lamina. The new species is endemic to the Western Ghats of Peninsular India, south of Coorg, and its distribution does not overlap with the range of L. flava, as far as it is known.

Etymology. The species is named after Dr. Abraham Samuel, a pioneer of odonatology from Kerala, for his contributions to the field and his constant encouragement to the authors. The specific epithet is a noun in the genitive case.

[Botany • 2026] Anaphalis rosmarinifolia (Asteraceae: Asteroideae: Gnaphalieae) • A New Species from southern Western Ghats, India

  

Anaphalis rosmarinifolia  Remya, K.M.P.Kumar & Maya, 

in Remya, Prabhukumar, Muhsina, Kanakambika, Smitha et Maya. 2026. 

Summary
Anaphalis rosmarinifolia, a new species of Asteraceae, from the slopes of stream banks of montane grasslands of the southern Western Ghats of Kerala and Tamil Nadu, India, is described and illustrated. The new species exhibits morphological affinities with its allied taxon, Anaphalis marcescens, in its habit, leaf shape, heterogamous and disciform capitula and 16, uniseriate, free, barbellate pappus bristles. However, it differs in habitat preference, coriaceous leaf texture, glabrous adaxial leaf surface, acute recurved leaf apex, sheathed leaf base, number of rows of phyllaries, type and nature of receptacle, number of florets and glandular indumentum in cypselae. A description of the new species, along with details on distribution and ecology and an illustration, colour photographs and comparison with its allied taxa, using SEM data of cypselae, are provided.

Key Words: Anaphalis marcescens, endemism, Nilgiri Biosphere Reserve, stenoendemic.

Anaphalis rosmarinifolia. A & B habit; C leaf, adaxial surface; D leaf, abaxial surface; E inflorescence; F foliar bract, adaxial surface; G foliar bract, abaxial surface; H capitulum; J – Q phyllaries; R receptacle, aerial review; S pistillate floret; T bisexual floret; U stamens; V pistil; W & X dimorphic pappus; Y cypsela.
photos: S. Remya & C. N. Maya.

Anaphalis rosmarinifolia Remya, K.M.P.Kumar & Maya sp. nov. 

Recognition. The new species is morphologically similar to Anaphalis marcescens (Wight) C.B.Clarke (Fig. 4) in overall habit, capitula type and the number, type and arrangement of pappus bristles. It differs from the latter by its habitat preference of wet rocks on the stream banks of montane grasslands (vs mud cliffs of montane grasslands in A. marcescens); coriaceous linear leaves (vs membranaceous linear); sheathing leaf base (vs decurrent); glabrous adaxial leaf surface (vs sparsely arachnoid midrib); leaf apex

Etymology. The specific epithet is based on the similarity of its leaves with those of rosemary (Salvia rosmarinus Spenn.), a medicinal and culinary plant in the Lamiaceae.

Kotharambath, Vengot & Gower, 2026 
 
 
Abstract
A new species of grandisoniid caecilian amphibian, Gegeneophis bavali sp. nov., is described based on two specimens from northern Kerala state in the southern part of the Western Ghats region of peninsular India. This species is distinguished from all other Gegeneophis by the combination of lacking an unsegmented terminal shield, having secondary annular grooves, and having more than 132 primary annuli. A new key to the identification of the species of the genus is presented.

[Herpetology • 2026] Nyctibatrachus kali • Hiding in plain sight: A New Species of Nyctibatrachus (Anura: Nyctibatrachidae) from the central Western Ghats, India


Nyctibatrachus kali 
Aravind, Ramesh, Naik, Gururaja & Priti, 2026


Abstract 
Frogs belonging to the genus Nyctibatrachus are endemic to the Western Ghats biodiversity hotspot. They are the second most speciose frogs in the Western Ghats, with 70% of the species having narrow distribution ranges. They are also highly cryptic in nature. In this study, we describe a new species of Nyctibatrachus frog from the central Western Ghats of India. Nyctibatrachus kali sp. nov. is described from the Kali River basin of North Karnataka. The new species is distinguishable from all 34 currently recognised Nyctibatrachus species by a combination of morphological, acoustic and phylogenetic analyses. Molecular phylogeny based on two mitochondrial genes (16S rRNA and ND1) reveals that it belongs to the N. sanctipalustris clade. Based on the analysis of 16S rRNA, Nyctibatrachus kali sp. nov. shows genetic divergence >5% with its congeners, and based on the analysis of ND1, Nyctibatrachus kali sp. nov. shows genetic divergence >10% with its congeners. The bioacoustics analyses indicated that the new species differed from their closest congeners based on the dominant frequency of the advertisement calls and the number of notes in each call. For the first time, we observed two distinct advertisement call categories–call notes with low and high dominant frequency in Nyctibatrachus kali sp. nov. and its congeners. Our study adds to the rich diversity of frogs from the Western Ghats of India.

 (A) Live individual of holotype; (B) Slow flowing stream habitat of the holotype with female and a clutch of eggs; (C) Dorsal view; (D) Ventral view; (E): Lateral profile of head and trunk; (F): Ventral view of hand; (G): Ventral view of foot; (H): third finger disc without dorso-terminal groove; (I): fourth toe disc with dorso-terminal groove cover notched distally; (J): Schematic view of webbing in hindlimb (black lines represents toes, curved black lines represents webbing, blue circles represents subarticular tubercle and orange circles represents toe discs.).

 Nyctibatrachus kali sp. nov. 

Diagnosis: Based on molecular phylogenetic analysis, Nyctibatrachus kali sp. nov. belongs to the N. sanctipalustris clade (Fig. 4) and is a sister lineage to N. dattatreyaensis. Hence, we compared Nyctibatrachus kali sp. nov. (both ♂ and ♀ individuals of type specimens) with all the species belonging to the N. sanctipalustris clade (both ♂ and ♀ individuals of type specimens), i.e., N. dattatreyaensis; N. karnatakaensis; N. kumbara; N. sanctipalustris; N. shiradi, N. tunga and N. vrijeuni.
