[Entomology • 2019] Undulivena thaiensis • A New Unique Leafhopper Genus of Erythroneurini (Hemiptera, Cicadellidae, Typhlocybinae) from Thailand

Undulivena thaiensis 

Song & Li, 2019

   DOI: 10.3897/zookeys.829.28718

Abstract

A new genus of the leafhopper tribe Erythroneurini (Cicadellidae, Typhlocybinae) from Thailand, Undulivena gen. n., and a new species Undulivena thaiensis sp. n., are described and illustrated. The new genus exhibits a unique feature of the forewing venation with CuA vein strongly sinuate.

Keywords: Auchenorrhyncha, Homoptera, morphology, new taxa, taxonomy

(♂): 1 habitus, dorsal view 2 habitus, lateral view 3 head and thorax, dorsal view 4 face.
 (♀): 5 habitus, dorsal view 6 habitus, lateral view 7 head and thorax, dorsal view 8 face 9 abdomen of female 10 forewing 11 hind wing.

Undulivena gen. n.

Type species: Undulivena thaiensis sp. n.

Diagnosis: The new genus is quite different from the other genera of the tribe Erythroneurini in view of the forewing venation, patterns of patches and chaetotaxy of the subgenital plate. The CuA vein of forewing is waved, which is unique among known Erythroneurini.

Remarks: 

The new genus is very similar to Salka (from Oriental and Palearctic regions) in body shape and male genitalia, e.g., pygofer with dorsal appendages, long dorsal macrosetae and a group of basolateral macrosetae, and the presence of a median anterior lobe on the connective. It differs from Salka in having the venation of the forewing with CuA strongly sinuate, which is unique among known Typhlocybinae, and the subgenital plate with a few lateral macrosetae in basal half. The color pattern of the forewing is also very unusual with veins margined with yellowish white, contrasting with the dark wings.

Etymology: The new generic name combines the Latin words undula and vena, referring to the undulate vein for the sinuate CuA vein of the forewing. The gender is feminine.

Undulivena thaiensis sp. n.

Diagnosis: The forewing has yellow-whitish stripes along veins. The style apex expanded, with inner margin tooth-like medially, and the aedeagal shaft spindle-shaped in ventral view, with single small subbasal process.

Etymology: The species is named for the type locality, Thailand. The name is adjectival.

[Herpetology • 2017] Fejervarya muangkanensis • A New Species of Rain-Pool Frog (Dicroglossidae: Fejervarya) from western Thailand

Fejervarya muangkanensis 

Suwannapoom, Yuan, Jiang, Yan, Gao & Che, 2017

Kanchanaburi Rain-Pool Frog  | ZooRes.ac.cn KIZ.CAS.cn 

Abstract  

We describe a new species, Fejervarya muangkanensis sp. nov., based on a series of specimens collected from Ban Tha Khanun, Thong Pha Phum District, Kanchanaburi Province, Thailand. The new species is easily distinguished from its congeners by morphological and molecular data, and can be diagnosed by the following characters: (1) small size (adult male snout-vent length (SVL) 33.5 mm; female SVL 40.0–40.9 mm); (2) tympanum small, discernible but unclear; (3) poorly developed toe webbing; (4) no lateral line system in adults; (5) characteristic “Fejervaryan” lines present in females; and (6) femoral glands absent. Molecular phylogenetic analysis of mitochondrial 16S rRNA further supports it as a distinct lineage and distinguishes it from its congeners for which sequences are available.

Keywords: Fejervarya muangkanensis sp. nov., Kanchanaburi, Thailand

Fejervarya muangkanensis 

Etymology: The specific epithet muangkanensis is derived from the common name of the Kanchanaburi province, Thailand. 

Suggested common names:  Kanchanaburi Rain-Pool Frog. 

Ecology: The species is found in small swamps in secondary forests at elevations between 700–900 m a.s.l. Advertisement calls of the males can be heard in small ponds from July to September in Thong Pha Phum, Kanchanaburi Province. Calling males are usually observed within or beside the swamp (Figure 6). 

Distribution: This species is currently known only from Thong Pha Phum, Kanchanaburi Province, western Thailand (Figure 1). 

DISCUSSION 

Although our discovery of F. muangkanensis increases the total number of Fejervarya species of Thailand to nine (Suwannapoom et al., 2016), the diversity of this group may still be underestimated. For example, previous molecular studies have identified several distinct lineages diverged from closely related, recognized species, including Fejervarya sp. hp3 from Pilok, Thailand, and Fejervarya sp. hp2 from Bangkok, Thailand (Kotaki et al., 2010). Future studies should examine morphological characteristics of specimens from these regions in detail to confirm their taxonomic identities. Moreover, as many areas of Thailand are still poorly or never surveyed for amphibian diversity, especially in southern Thailand, unrecognized diversity of the genus could still exist. Closer inspections of previously collected congeners from these regions are necessary to better understand amphibian diversity in Thailand, which could help to manage and conserve this unique diversity effectively.

Garra fluviatilis  

Kangrang, Thoni, Mayden & Beamish, 2016

  DOI: 10.11646/zootaxa.4175.4.3 

Abstract

Garra fluviatilis is a new species described herein from the Kwai Noi, Mae Khlong basin, in the Thong Pha Phum District of Kanchanaburi Province in western Thailand. It is diagnosed by the following combination of morphological characters: well developed upper lip with unculiferous papillae, mottled pigmentation pattern, a pleated papilliferous fold at the junction of the anterolateral lobe and anteromedial fold on the lower lip, 4–5 anal scales, relatively deep body, keeled nape, and a laterally straight anterior margin of the anteromedial fold. Based on shared apomorphic morphological characters, we hypothesize that the new species is most closely related to G. spilota in nearby Myanmar.

Keywords: Pisces, Mae Khlong basin, new species

Abstract

The millipede subfamily Alogolykinae and the tribe Alogolykini are recorded in Thailand for the first time, being represented there by Tetracentrosternus theelorsuensis sp. n. While the new species has characteristics that place it in the genus Tetracentrosternus, it also shows a number of unique features that make it necessary to rediagnose this Oriental genus, as well as to key its three currently known species and map their distributions. The tribes Alogolykini and Polydrepanini, as well as the subfamily Alogolykinae are also briefly redefined.

Dendrelaphis nigroserratus   

Vogel, Rooijen & Hauser, 2012 

Abstract

A new species of the colubrid genus Dendrelaphis Boulenger 1890 is described. Dendrelaphis nigroserratus sp. nov. occurs in a part of West Thailand as well as in the extreme south of Myanmar. Morphologically, D. nigroserratus sp. nov. is similar to D. cyanochloris (Wall, 1921) with which it occurs sympatrically. It is distinguished from the latter by its highly conspicuous neck coloration, high incidence of paired postparietal shields and its much larger size. In coloration, it resembles

D. striatus (Cohn, 1906) from which it is distinguished by several aspects of its morphology. The discovery of D. nigroserratus sp. nov. underscores the notion that the hilly western parts of Thailand are in need of further exploration.

Key words: Dendrelaphis cyanochloris, Dendrelaphis nigroserratus sp. nov., Dendrelaphis striatus, Indochina, Southeast Asia, taxonomy

Abstract

A new Bent-toed Gecko, Cyrtodactylus phetchaburiensis sp. nov. is described from the Tha Yang District of Phetchaburi Province, western Thailand. It is a medium-sized Cyrtodactylus (SVL to at least 63.2 mm), with small, mostly keeled tubercles in 20 regular longitudinal rows on dorsum; 33 scales across mid-venter between lowest rows of flank tubercles; enlarged row of femoral scales present; five precloacal pores in male, femoral pores and precloacal groove absent; 5–6 broad basal lamellae and 11 narrow distal lamellae beneath digit IV of pes; and a single median row of transversely enlarged subcaudal scales present. It has a dorsal colour pattern of large, dark, diffusely-edged markings on a fawn background and a pair of dark scapular patches. The species is a member of the Central Indochinese (Thai-Myanmar) clade of Cyrtodactylus and is most closely related to C. oldhami (Theobald), from which it differs in colour pattern.

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.

 Abstract 

On 5 December 2012 we observed a Yellow-throated Marten Martes flavigula and a Changeable Hawk Eagle Nisaetus cirrhatus feeding on a recently dead Red Muntjac Muntiacus muntjak in Huai Kha Khaeng Wildlife Sanctuary, western Thailand. It seems unlikely that the Marten had killed the deer. It perhaps came across the carcase shortly after it died, possibly from a snake bite.

DOI: 10.2108/zs140238

 Abstract

We report a new tree frog of the genus Gracixalus from western Thailand and describe it as a new species Gracixalus seesom based on results of morphological and molecular analyses. The new species is a small-sized Gracixalus (male snout-vent length ca. 22 mm) and is morphologically similar to G. gracilipes, but is easily distinguished from it by its dorsal tan color in life, absence of white spot on lower lip, and black markings on its foot webbing. The new species also clearly differs from all the other members of the genus by the combination of small body size, triangular snout, and light yellowish brown dorsum without distinct tuberculations. Problems of phylogeny and taxonomy of the genus Gracixalus are briefly discussed.

DOI: 10.11646/zootaxa.3869.1.6

Abstract

We describe Cyrtodactylus saiyok sp. nov. from a dry evergreen forest on a limestone hill in Khao Krajae, Sai Yok District, Kanchanaburi Province, western Thailand. It is characterized by a maximal known SVL of 61.0 mm; 18–19 longitudinal rows of dorsal tubercles; 23 or 24 ventral scale rows between ventrolateral skin folds; a continuous series of enlarged femoro-precloacal scales, including 5 pore-bearing precloacal scales (males); no precloacal groove or depression; transversely enlarged subcaudal scales; a complete black nuchal loop; a W-shaped band above shoulders and 3–5 irregular, medially interrupted or not, black dorsal bands between limb insertions. Cyrtodactylus saiyok sp. nov. is the sixth reptile species that is possibly endemic to Sai Yok District.

Keywords: Cyrtodactylus saiyok sp. nov., new species, taxonomy, limestone



Etymology. The specific epithet saiyok refers to the name of the district in which the type locality is situated. It is a noun in apposition, invariable. We suggest the following common names: Took-kai Sai Yok (Thai), Sai Yok bent-toed gecko (English), Cyrtodactyle de Saï Yok (French), Saiyok Bogenfingergecko (German), Saiyokkromvingergekko (Dutch). The common name Sai Yok Bent-toed Gecko had been proposed by Ellis and Pauwels (2012) for Cyrtodactylus tigroides, for which we here propose the new common name Tiger Bent-toed Gecko.

[Entomology • 2014] Ampulex dementor • The Soul-Sucking Wasp by Popular Acclaim – Museum Visitor Participation in Biodiversity Discovery and Taxonomy

Abstract

Taxonomy, the science of describing and naming of the living world, is recognized as an important and relevant field in modern biological science. While there is wide agreement on the importance of a complete inventory of all organisms on Earth, the public is partly unaware of the amount of known and unknown biodiversity. Out of the enormous number of undescribed (but already recognized) species in natural history museum collections, we selected an attractive example of a wasp, which was presented to museum visitors at a special museum event. We asked 300 visitors to vote on a name for the new species and out of four preselected options, Ampulex dementor Ohl n. sp. was selected. The name, derived from the ‘soul sucking’ dementors from the popular Harry Potter books is an allusion to the wasps' behavior to selectively paralyze its cockroach prey. In this example, public voting on a scientific name has been shown to be an appropriate way to link museum visitors emotionally to biodiversity and its discovery.

Abstract

Carnivorous land snails attributed to the genera Indoartemon Forcart, 1946 and Carinartemis, new genus, are recorded from Thailand for the first time. Indoartemon eburneus (Pfeiffer, 1861), I. prestoni (Gude, 1903) and I. medius, new species, were collected from central and northeastern Thailand. These two genera are easily distinguished: Carinartemis, new genus, possesses a distinctive sharp and wide peripheral keel that does not occur in Indoartemon. We provide the first description of the internal anatomy of Indoartemon and Carinartemis, new genus, and establish the presence of several distinctive characters. The new genus has two new distinctive species, Carinartemis vesperus, new species, and Carinartemis striatus, new species, from isolated limestone hills in western Thailand.
