A New Species

A new species of Platybaetis viz., P. selvai sp. nov. is described herein based on larval collections from Tangon stream in the state of Arunachal Pradesh in Eastern region of Indian Himalaya. It can be differentiated by the following combination of characters: (i) posterior margin of abdominal segments I–X with rounded ‘U’ shaped spines; (ii) anterolateral margin of gills I–VII with minute setae; (iii) claw with 7–8 denticles; (iv) paracercus composed of 10–11 segments; (v) hindwing pads reduced, small. Brief ecological notes are appended.

Polygonatum Miller (1754: without pagination) (Asparagaceae, Nolinoideae) is a relatively large genus with great diversity of plant form, habit, and ecology. Most of the diversity is found in the Hengduan of southwestern China and the eastern Himalaya (Jeffrey 1980, Chen & Tamura 2000). Field observations at several localities in Arunachal Pradesh, India and specimen examinations of an anomalous opposite leaved species from the eastern Himalaya (incl. southeastern Tibet) could not be placed in any currently described species (Baker 1875, Hooker 1894, Tang 1978, Jeffrey 1980, Wu 1983, Noltie 1994, Chen & Tamura 2000, Floden 2015). Comparisons to the type specimens of all opposite-leaved species, examination of species in the field, examination of over 6,000 specimens of Polygonatum from multiple herbaria through loans or visits (CAS, F, H, MI, MO, NY, and PE, acronyms follow Thiers 2018) and digital images (BM, E, HITBC, IBSC, K, KUN, L, LBG, P, and SZ) confirms the novelty of this species. In addition, molecular phylogenetic analysis (A. Floden, in preparation) of 250+ samples of Polygonatum including two nuclear genes and chloroplast data have confirmed the molecular distinctiveness of this new species and its placement in the opposite-leaved group of species found in the Himalaya.

A New Species

A new species of nemachilid loach Aborichthys barapensis, is described based on two adult specimens (91 and 97 mm SL) from the Barap Stream (a tributary of the Brahmaputra River basin) in the southeastern most part of the state of Arunachal Pradesh bordering Myanmar. The new species is distinguished from its congeners in having a narrow black basicaudal bar without a black ocellus on the upper end (vs. present); and in having a very low dorsal and ventral adipose crests (vs. prominent; absent in A. waikhomi). The new species is further distinguished from its congeners by the following combination of characters: body with 24–26 oblique bars along the flank; interspace narrower than bars on body; moderately rounded caudal fin with five distinct black to brown cross bars; vent closer to the caudal-fin base (44.1–45.1 % standard length) than to snout tip.

Abstract. Borah D, Singh RK, Thungon LT. 2021. Short Communication: Cremanthodium indica (Asteraceae, Senecioneae), a new species from the Eastern Himalaya, India. Biodiversitas 22: 1268-1272. Cremanthodium indica D.Borah, R.Kr. Singh & Thungon (Asteraceae, Senecioneae), a new species from Eastern Himalayan state Arunachal Pradesh, India is described and illustrated. The new species is allied to Cremanthodium nobile (Franch.) Diels ex H.Lév. in having elliptic-obovate basal leaves, solitary, nodding capitula and hemispheric involucre, but differs by densely pale yellow tomentose stem, stem leaves 5–9, 1.6–2.1 cm distant, outer phyllaries 2.3–2.8 mm wide, inner phyllaries elliptic, 3–5 mm wide, apex acute, ray lamina creamy, oblong, 2–2.3 cm long, apex truncate, distinctly 3-dentate, ray tube 1.5–2 mm long, tubular florets creamy, 8–9 mm long and pappus 6–8 mm long.

A new species, Rubus haridasanii, from Arunachal Pradesh, Eastern Himalaya, is described and illustrated. It is closely related to Rubus preptanthus but differs by the presence of caudate-acuminate leaves, 5–6-flowered inflorescences, stipitate glandular pedicels and calyx, delicate needle-like prickles on the calyx, caudate apex of the sepals. The distinct foliar as well as floral morphology of R. haridasanii differ from all previously described species of Rubus. Differences in key morphological characters of R. haridasanii and R. preptanthus are also tabulated. In addition, pollen morphology is described based on light (LM) and scanning electron microscopy (SEM).
