 Abstract

 A new species of glossiphoniid leech, Helobdella viridoclypus, is described from the northern region of Thailand, representing the first record of the genus Helobdella from the country and Southeast Asia. Its characteristics are similar to those of the type species, H. stagnalis, but can be distinguished by its transparent rice-shaped and triannulated body, cephalisation, a single pair of dark eyes, a smooth dorsal surface without papillae, rich darkgreen pigmentation on the dorsum, six pairs of crop caeca with less developed first pair and unbranched second to sixth pairs (posterior caeca), male and female gonopore separated by a single annulus, and a triangular nuchal scute pointed backwards with yellowish-green colouring around the mid-dorsal region. The phylogenetic relationships of H. viridoclypus, new species, are clarified, showing that it is monophyletic within the stagnalis species-complex clade which includes H. adiastola, H. octatestisaca, H. modesta, and the type species H. stagnalis. The new species is a free-living leech that specifically preys on invertebrates and not on humans.

Abstract

A new species of Microchirita from Northern Thailand, Microchirita maxima Triboun, Thamwanna & Kaewkarn, is described and illustrated. It is diagnosed against the other species in Thailand with axillary bracteate inflorescences. Their seed morphologies are also provided.

 

Keywords: new species, limestone, Microchirita, Gesneriaceae, Thailand

Microchirita maxima Triboun, Thamwanna & Kaewkarn sp. nov.

Diagnosis: Microchirita maxima is similar to M. glandulosa C.Puglisi, M. involucrata (Craib) Yin Z.Wang and M. rupestris (Ridl.) A.Weber & Rafidah in having bracteate inflorescences. It differs from M. glandulosa and M. rupestris by having a generally taller stem, the bracts are free (vs joined across the stem at the very base in M. glandulosa and fused into a tube in M. rupestris), often longer pedicels (5–35 mm long in M. maxima vs 8–12 mm long in M. glandulosa and 0.1–15 mm long in M. rupestris), and a yellow stripe on the ventral surface of the corolla (vs lacking in M. glandulosa and M. rupestris). It also differs from Microchirita involucrata in the bract margin (serrate or serrulate in M. maxima vs entire in M. involucrata), wider calyx lobes (1.4–1.5 mm wide in M. maxima vs 0.7–1.4 mm in M.

involucrata) and the paler purplish flowers. 

Etymology. The specific epithet refers to the large size of the plant and the rather tall stem.

Vernacular. Yad wai ya but (หยาดไวยบุตร), name given here.

เห็ดขอนขาวสายสมร  ||  DOI: doi.org/10.11646/phytotaxa.705.2.2 

 

Abstract

A new edible Lentinus species, described herein as L. saisamorniae, was collected from local markets and natural habitats in northern Thailand between 2019 and 2021. This species is characterized by its small to medium-sized basidiomata, white to yellowish-white pileus, broadly ellipsoid to elongate-shaped basidiospores, dimitic hyphal system, and hyphal pegs. Nonetheless, its longer basidia and smaller basidiospores make it distinguishable from L. cladopus. A molecular phylogenetic analysis of the combined internal transcribed spacer (ITS) large subunit (nrLSU) of nuclear ribosomal DNA, and RNA polymerase II large subunit (rpb1) sequences supported the monophyly of L. saisamorniae as a distinct lineage within the genus Lentinus. Therefore, this new species was introduced based on both morphological characteristics and molecular phylogeny. A full description, illustrations, color photographs, and a phylogenetic tree to show the placement of L. saisamorniae are provided. Comparisons between the new species and morphologically similar and related species are discussed.

Abstract

A new scorpion species, Scorpiops (Euscorpiops) doiphukha sp. nov., belonging to the family Scorpiopidae Kraepelin, 1905, is described based on 12 specimens of both sexes (three adults and nine immatures) collected in Doi Phu Kha National Park, Nan Province, Thailand. The new species presents key features exhibited by scorpions of the subgenus Euscorpiops and can be characterized notably by a large size, a sexual dimorphism strongly marked with male pedipalps elongated, a distinct trichobothrial pattern and other morphological features. This new taxon represents the 115th species among the currently recognized species for the genus Scorpiops Peters, 1861, and the 44th species described for the subgenus Euscorpiops Vachon, 1980. It is likely an endemic element of Thailand’s scorpion fauna, raising the number of known Scorpiops (Euscorpiops) species in the country to 13. Ecological and distributional aspects of the new species are discussed and compared with closely related Scorpiops species, highlighting its distinctiveness within the genus.

Abstract

Protosticta jirapornae sp. nov. is described and illustrated based on specimens of both sexes collected from Chiang Mai Province, Thailand. This taxon was previously recognised as the northern population of P. khaosoidaoensis Asahina, 1984, which is geographically isolated from its type locality in Chanthaburi Province, eastern Thailand. The new species can be distinguished from P. khaosoidaoensis and other closely related congeners by the distinctive markings on the prothorax and synthorax in both sexes, as well as the structure of the male anal appendages and the morphology of the genital ligula.

Abstract

Thailand hosts a diverse array of plants in the Zingiberaceae family, with over 150 endemic species, highlighting its significance in global biodiversity. The genus Cornukaempferia stands out for its ornamental and medicinal value. During a research expedition in Northern Thailand, a previously unknown Cornukaempferia species was discovered in Sukhothai province, expanding the known distribution range. It was confirmed through comprehensive taxonomic analysis as a new species, Cornukaempferia puangpeniae. Additionally, a new variety, C. aurantiiflora var. vespera, was identified in Uttaradit Province. The genus now encompasses eight species and two varieties with the addition of these taxa, exhibiting a notable prevalence in Thailand and highlighting its significant endemism. Particularly, C. larsenii is noteworthy for being native to Thailand and Laos. Detailed morphological descriptions, including diagnoses with related taxa, were provided. The species' ecological characteristics, pollen morphology, traditional uses, and conservation status were documented. A revised key to species and varieties in the genus Cornukaempferia, including a UPGMA cluster analysis dendrogram elucidating morphological relationships within the genus, was presented. These discoveries contribute to the botanical knowledge of the region, underscoring the importance of continued exploration and conservation efforts in preserving its rich flora.

Abstract

Curcuma lampangensis Saensouk, Maknoi & Rakarcha and C. sabhasrii Saensouk, Maknoi, Wongnak & Rakarcha, two new species of ginger family (Zingiberaceae) from northern Thailand, are described, illustrated and photographed. Additionally, the authors provide their detailed morphological descriptions, as well as illustrations, color photographs, distributions, ecology, etymology, phenology, vernacular, conservation status and its closely related species. The two new species are assignable to the Curcuma subgenus Ecomatae. Curcuma lampangensis and C. sabhasrii are endemic to Lampang and Phitsanulok provinces of northern Thailand, respectively. The morphological characteristics of C. lampangensis are compared to C. rhomba J. Mood & K. Larsen while C. sabhasrii is compared to C. peramoena Souvann. & Maknoi. Curcuma lampangensis is recognized by its glabrous on nearly all parts of the plant, creeping rhizome and the inflorescence usually arises from a new rhizome branch next to the existing pseudostem, flowers that are white to pale pink and white to pale yellow labellum with 2 dark yellow bands at the center and reddish tinge at the base. Curcuma sabhasrii is recognized by having 8-15 greenish to reddish-purple bracts, reddish-purple corolla lobes, white with reddish-purple mottling to reddish-purple staminodes and labellum which is reddish-purple with an embossed yellow path along the midrib from base to apex and reddish-purple mottling on yellow mid-band of lower half. A key to 24 species of Curcuma subgenus Ecomatae in Thailand is presented.

Abstract

A new species, Chiloschista breviseta (Orchidaceae: Epidendroideae: Aeridinae) from Northern Thailand is described and illustrated, and notes on ecology and conservation status are provided. Chiloschista breviseta is morphologically similar to C. usneoides but differs in having much shorter seta on each side of the anther cap. Previous records of C. usneoides from Thailand refer to C. breviseta.

Diagnosis: Chiloschista breviseta is similar to C. usneoides in the largely white flower and the shorts accate lip with a rudimentary mid-lobe, but differs in having a short seta (<0.3 mm long) on each side of the anther cap (vs. a long, thread-like seta, >1.7 mm long) and in the Y-shaped callus apex (vs. T-shaped). It can be distinguished from C. viridiflava Seidenf. in having a glabrous abaxial surface of sepals and petal (vs. pubescent), margin of petals entire (vs. erose), and white sepals and petals, sometimes with a purplish pink median line abaxially (vs. pure pale green), and in having short setae (vs. setae > 1.9 mm long).

Etymology: From the Latin brevis, short, and seta, a bristle-like hair, referring to the short appendages on the anther cap, unlike the long wiry appendages seen in species like C. usneoides
