DOI: 10.1111/njb.00889

Aristolochia phuphathanaphongiana Do sp. nov. from southwestern Thailand is described here. The new species is most similar to A. acuminata and A. kongkandae, but it is distinguished by having a broad-ovate to cordate bracteole that is sessile and 8–15 × 6–12 mm, the entire perianth being dark purple to maroon black, with lanceolate limb and abaxial surface densely covered with long grey hairs, as well as by non-winged seeds. In addition to the description, a key to the species of Aristolochia subsect. Podanthemum from the Himalayan region and Indochina is provided.

Abstract

A new Begonia species from Laos and Thailand is described. It belongs to Begonia sect. Tetraphila, along with 30 other species which are all endemic to Africa. This is the first record of any of the 65 currently accepted sections in Begonia transgressing continental borders. A dated molecular phylogeny places the split of the new Asian species from its African congeners during the late Miocene to the early Pleistocene. As the species is a hygromesophilous epiphyte limited to tropical forest, no suitable corridor for migration existed during that time and the cause of the Afro-Asian disjunction probably is a long-distance dispersal event. The discovery of Begonia afromigrata emphasises the importance of chance in the assembly of tropical floras.

Keywords: Begonia sect. Tetraphila; long-distance dispersal; phylogeny 

Habitat and ecology. – Without exception in field notes the plant is described as epiphytic, growing between 5 and 15 m above ground level. It has been noted as growing on a Spondias species (Anacardiaceae; P. Tribune, pers. comm.). Usually collected on dead trees or fallen branches in evergreen forest (more rarely deciduous forest) on limestone, between 600 m and 1900 m altitude. Found more often on tree trunks than smaller branches. Plants cultivated from cuttings always produce one or more male inflorescences first, followed later by female inflorescences.

[Ichthyology • 2012] Schistura tenebrosa • A New Species of Loach (Teleostei: Nemacheilidae) from the Kwai Noi River system, Mae Khlong basin, western Thailand

Schistura tenebrosa Kangrang, Page & Beamish 2012

Abstract

A new species of Schistura is described from the Kwai Noi, Mae Khlong basin, in the Thong Pha Phum District of Kanchanaburi Province in western Thailand. The species is distinguished from all other species of Schistura by a uniform dusky brown color pattern without marks on the dorsum or side of body and with many conspicuous supplementary neuromasts along the lateral line and on the head. It is further distinguished from other species of Schistura lacking marks on the body by its dark brown color, an incomplete lateral line extending only to beneath the dorsal fin, and the origin of the dorsal fin located above the origin of the pelvic fin. The species is small, reaching only 46.0 mm SL, 55.1 mm TL, and inhabits shallow gravel and rubble riffles in small streams. 

Key words: loach, Cypriniformes

Type locality: Thailand, Kanchanaburi Prov., Thong Pha Phum, Mae Khlong basin, Kwai Noi River system, Pakkok River, 14º36'22"N, 98º28'14"E.

Etymology: The name tenebrosa is a Latin adjective for dark or gloomy, and was given in reference to the dusky color of this species.

Distribution.— Pakistan, Nepal (type!), India, Sri Lanka, Myanmar, SOUTH-WESTERN Thailand.

Ecology.— Low limestone hills (Thailand). Elsewhere: in open grassland, on open dry rocky slopes, on fringes of coniferous forest; also in seasonally moist areas near streams, growing in sandy and clayey soils; mostly in fi re-prone habitats. Altitude: 180 m (Thailand). Elsewhere (65–)250–2000 m. Flowers: December (Thailand). Elsewhere November, January–July

[Ichthyology • 2013] Kryptopterus vitreolus | ปลาผี, ปลาก้างพระร่วง หรือปลากระจก • After eighty years of misidentification, a name for the glass catfish (Teleostei: Siluridae) from Thailand

Kryptopterus vitreolus Ng & Kottelat 2013

Abstract

We resolve the identity of the glass catfish, a species of Asian freshwater fish commonly encountered as an ornamental fish and an experimental subject that has long been misidentified as either Kryptopterus bicirrhis or K. minor. Our study indicates that the glass catfish is an unnamed species distinct from either, which we describe here as Kryptopterus vitreolus.

Kryptopterus vitreolus is known from river drainages in peninsular and southeastern Thailand, and is distinguished from congeners in having a combination of: transparent body in life, maxillary barbels reaching beyond the base of the first anal-fin, dorsal profile with a pronounced nuchal concavity, snout length 29–35% head length (HL), eye diameter 28–34% HL, slender body (depth at anus 16–20% standard length (SL)) and caudal peduncle (depth 4–7% SL), 14–18 rakers on the first gill arch, and 48–55 anal-fin rays.

Key words: Peninsular Thailand, Kryptopterus

Miliusa longiflora (Hook.f. & Thomson) Baill. ex Finet & Gagnep.

ABSTRACT

Miliusa longiflora, newly recorded from Kanchanaburi, Thailand, is described and illustrated.

The genus Miliusa Lesch. consists of ca. 45 species distributed mostly in Asia (Kessler et al. 2000). About 15 species have been recorded for Thailand (Mols and Kessler 2003). The latest newly described species, M. tirunelvelica, was described on material from India by Murugan et al. (2004).

[Ichthyology • 2011] ปลาค้อทองผาภูมิ | Schistura aurantiaca • A New Species (Teleostei: Nemacheilidae) from the Mae Khlong basin, western Thailand

Schistura aurantiaca  Plongsesthee, Page & Beamish 2011

Schistura aurantiaca, new species, is described from the Mae Khlong basin in western Thailand. It is distinguished from all other species of Schistura by a unique color pattern of 3-9 orange bars on the side of the body, with the 1st bar immediately behind the head and the 2nd bar near the dorsal-fin origin and widely separated so that most of the nape and the anterior side of the body are uniformly brown. The species reaches only 41 mm SL and inhabits shallow gravel and rubble riffles in small streams.

Etymology. The name, aurantiaca, Latin adjective for orange-colored, is in reference to the orange bars on this species.
