ABSTRACT

Sixteen species of Issidae (Hemiptera: Fulgoromorpha) were recorded in a single day of collecting in Dong Son-Ky Thuong Nature Reserve, Quang Ninh Province, Vietnam, of which a checklist is provided. Among them, eight species are new to science and described in different tribes and subtribes: in the Hemisphaeriini Hemisphaeriina: Gergithoides olivaceus sp. nov., Hemisphaerius bresseeli sp. nov. and Neogergithoides scapularis sp. nov.; Hemisphaeriini Mongolianina: Mongoliana vietnamica sp. nov.; Kodaianellini: Kodaianella mua sp. nov.; Parahiraciini Parahiraciina: Pusulissus quangninhensis sp. nov. and Rostrolatum curviceps sp. nov.; Sarimini: Pseudocoruncanius obliquus sp. nov. The new genus Melichergithus gen. nov. is described to accommodate Gergithus gravidus Melichar, 1906 and the new combination Melichergithus gravidus (Melichar, 1906) gen. et comb. nov. is proposed; a black form of the species is recorded for the first time and described. Two species, Longieusarima lunulia Wang, Bourgoin & Zhang, 2017 and Parallelissus fuscus Meng, Qin & Wang, 2020, are recorded from Vietnam for the first time, while another species Maculergithus luteomaculatus (Constant & Pham, 2016) is recorded for the first time from Quang Ninh Province. Four species were represented by single females that could not be identified to species level, belonging to the genera Clypeosmilus Gnezdilov & Soulier-Perkins, 2017, Fortunia Distant, 1909 (two species) and Kodaianellissus Wang, Bourgoin & Zhang, 2017. The five following genera are recorded from Vietnam for the first time: Kodaianella Fennah, 1956, Rostrolatum Che, Zhang & Wang, 2020, Longieusarima Wang, Bourgoin & Zhang, 2017, Parallelissus Meng, Qin & Wang, 2020 and Kodaianellissus. The type material of Hemisphaerius rufovarius Walker, 1858 and its junior synonyms H. scymnoides Walker, 1862, H. testaceus Distant, 1906 and H. virescens Distant, 1906 was studied and the male terminalia described; as a result, H. rufovarius is removed from the fauna of Vietnam and China. Hemisphaerius bipunctatus Melichar, 1906 is also removed from the fauna of Vietnam after examination of the corresponding specimens. This study provides a 25% increase in the number of Issidae of Vietnam; a complete list of the 51 species recorded from the country, as well as a map of the number of recorded species per province, are given and discussed.

Abstract

During botanical expeditions focused on the study of Annonaceae in Thailand, specimens resembling Friesodielsia glauca were collected from the lower part of peninsular Thailand but were believed to differ from that species in vegetative, flower, and fruit characters. A morphological investigation of the new specimens and species complex was conducted. Specimens (including types of F. glauca and similar species collected from Thailand and adjacent regions) were examined in the following herbaria: A, BK, BM, BKF, E, K, KEP, KKU, L, PSU, QBG, SING, and US. As a consequence, the new species Friesodielsia parvimitra, endemic to peninsular Thailand, is described and illustrated. The conservation status of the new species was provisionally assessed as Critically Endangered (CR, B2ab(iii)) following the IUCN’s guidelines. In addition, F. argentea, previously regarded F. glauca, is reinstated here as a distinct species based on several morphological differences and is reported as a new record from Thailand. Photographs, line drawings, and a revised key to F. glauca and similar species are presented.

Friesodielsia parvimitra Satthaphorn & Leerat., sp. nov.

Diagnosis: Friesodielsia parvimitra superficially resembles F. glauca in having inner petals shorter than half of the length of its outer petals, but differs in its non-glaucous lower leaf surface, much shorter flower pedicels (12–16 mm long vs. 20–40 mm long in F. glauca), shorter bracts (0.5–0.8 vs. 0.9–1.7 mm long), reduplicate sepals 2–3 mm long (vs. non-reduplicate sepals 4.0–5.5 mm long), and inner petals 4–5 mm long with puberulous appressed hairs on the outside surface (vs. 7–10 mm long with a glabrous outside surface).

 

Etymology: The specific epithet pertains to the inner petals that are connivent and short (less than 5 mm long), resembling a headdress.

Abstract

A new macrofungal species, described herein as Gloeocantharellus thailandensis, was collected from southern Thailand in 2022. This species is characterized by gomphoid basidiomata, pale red to pastel red pileus, broadly ellipsoid to elongated basidiospores with verrucose ornamentation, and abundant gleoplerous hyphae. Multi-gene phylogenetic analyses of the internal transcribed spacers (ITS) and large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA), and the mitochondrial ATPase subunit 6 (atp6), also revealed that the position of G. thailandensis is well supported within the genus Gloeocantharellus, but distinct from other previously known Gloeocantharellus species. This is the first record of the genus in Thailand. Comprehensive descriptions, colour photographs, line-drawing illustrations, and comparisons with morphologically similar and phylogenetically related species are provided.

ดอกดินไข่ปลา  ||  DOI: 10.3767/blumea.2024.69.01.03

Abstract 

Kaempferia subglobosa (Zingiberaceae) is described and illustrated as a new species of Kaempferia subg. Protanthium from Tak Province, northern Thailand. It can easily be distinguished from all other species of subg. Protanthium by having branched storage roots with numerous, tiny, lateral and terminal subglobose to ovoid tubers. The diagnostic characters of this taxon are discussed and compared with those of the morphologically most similar species K. rotunda. Detailed photographs of plants and dissected flowers, and information on phenology, distribution and ecology, are provided. Interestingly, a red dwarf honeybee, Apis florea, is likely a pollinator. The IUCN conservation status of Vulnerable is assigned for K. subglobosa. In addition, the names K. uttaraditensis and K. kamthornii are synonymized with K. albiflora and K. takensis, respectively. As a result of this taxonomic revision, the Flora of Thailand currently harbours 14 species of the subgenus of which 9 strictly endemic. Two alternative updated identification keys for Kaempferia subg. Protanthium are also presented.

Kaempferia subglobosa Noppornch. & Jenjitt., sp. nov. 

(subg. Protanthium) 

Similar to Kaempferia rotunda L. in overall habit, inflorescences and flower colour, but differs in having the branched storage roots with numerous, tiny, lateral and terminal subglobose to ovoid tubers (vs storage roots not branched, consisting of a single, large, terminal fusiform, ellipsoid to ovoid tuber), ligules 7–14 mm long, opaque (vs ligules 1–3(–5) mm long, translucent), labellum narrowly obovate with an incision around 1/3 of its length (vs labellum obdeltoid to broadly obovate with an incision around 1/2 of its length), and the anther crest bifid apex with apices aristate, incision serrate to undulate, incision base angular (vs anther crest bilobed apex with apices acute, incision entire, usually with 2–3 small teeth between incision base).

 Etymology. The specific epithet ‘subglobosa’ refers to the unique characteristic of the species, the branched storage roots with numerous, tiny subglobose tubers absent in all known taxa belonging to Kaempferia subg. Protanthium.

Abstract

We described a new species of elapid snake genus Bungarus from the Tenasserim Mountain Range in Ratchaburi Province, western Thailand. Bungarus sagittatus sp. nov. can be distinguished from all congeners by having the combination of 15 dorsal scale rows; 215–217 ventral scales; 48–56 undivided subcaudal; prefrontal suture 2.4–2.6 times length of internasal suture; anterior chin shields larger than posterior chin shields; head of adult uniform black while juvenile black with small dim white patches on temporal and parietal areas; dorsal body black, with 25–31 white narrow bands, white and black bands at midbody covering 1.5–3.0 and 4.5–6.0 vertebral scales, respectively; dorsal body black bands not intruding ventrals or intruding ventrals less than 0.5 times of width of outer dorsal scales; ventral surface of body immaculate white; ventral side of tail white with a row of dark brown triangular patches on middle pointing posteriorly; tail relatively long, tail length/total length 0.140–0.143. Genetically, the new species has uncorrected pairwise divergences of ≥ 8.29% of the mitochondrial cytochrome b from other Bungarus species. Currently, the new species is only known from the type locality.

Paratypes in life showing the variation in different age class.
A. Subadult female (ZMKU R 01088); B. Juvenile (ZMKU R 01090).

Bungarus sagittatus sp. nov.

Diagnosis: Bungarus sagittatus sp. nov. is assigned to the genus Bungarus by its recovered phylogenetic position and having enlarged, hexagonal-shaped, midbody vertebrae scales (Smith 1943; Slowinski 1994). This species can be distinguished from other species of Bungarus by the following combination of characters: 15–15–15 dorsal scale rows; 215–217 ventral scales; 48–56 undivided subcaudal; prefrontal suture 2.4–2.6 times length of internasal suture; anterior chin shields larger than posterior chin shields; head of adult uniform black while juvenile black with small dim white patches on temporal and parietal areas; dorsal surface of body black, with 25–31 white narrow bands, white and black bands at midbody covering 1.5–3.0 and 4.5–6.0 vertebral scales, respectively; dorsal black bands of body not intruding ventrals or intruding ventrals less than 0.5 times of width of outer dorsal scales; ventral surface immaculate white; ventral side of tail white with a row of dark brown triangular patches on middle pointing posteriorly; tail relatively long, tail length/total length = 0.140–0.143.

Etymology: The specific epithet sagittatus is derived from sagittata (L.) meaning arrow and in reference to the dark triangular shape on subcaudals which resembles a barbed arrow.

Distribution: Bungarus sagittatus sp. nov. is currently known from type locality: Khao Krachom, Suan Phueng District, Ratchaburi Province. The area is part of Tenasserim Mountain Range, which lies on Thai-Myanmar borderline.

[Mollusca • 2024] Phestilla arnoldi • Parasites or Predators? Gastropod Ectoparasites (Nudibranchia: Trinchesiidae) and their scleractinian host Corals at Koh Tao, Gulf of Thailand, with the Description of A New Species

Abstract

Recent years have seen a rapid increase in the study of coral-associated gastropods. In particular, the description of several new species in conjunction with their host specificity or dietary variability, has raised questions pertaining to their impact on reef health. These corallivores have been labelled as both ‘parasite’ and ‘predator’ by different studies, due to the tendency of some species to entirely consume their ‘host’ corals. Here we present new findings of corallivory and parasitism based on surveys conducted on the reefs of Koh Tao, Gulf of Thailand. A total of 6566 corals were assessed for their tendency to host gastropods of the nudibranch genus Phestilla and the caenogastropod family Epitoniidae. Thirteen gastropod species were found to be associated with 20 scleractinian coral species, including six that do not match the original description of previously known taxa. Herein we describe one of them, the first nudibranch proven to be associated with corals of the scleractinian genus Acropora and discuss conservation implications of these coral/gastropod relationships. Additionally, we explore the complex topic of defining these relationships as parasitic versus predatory and the merits of using these labels to better understand the ecology of these relationships.

Abstract

Prosopanche cocuccii is described as a new species from Southern Brazil. It resembles P. bonacinae due to the trigonous rhizome and by the general size of the flower organs. Nevertheless, P. cocuccii is distinguished by the main floral morphological characteristics used to differentiate species. In addition, the new species presents some rare characters for the genus, such as a highly branched rhizome and flowers usually grouped in fascicles. We provide a description, illustrations, field photographs, morphological details under the stereomicroscope, and comments on habitat, ecology, distribution, and conservation of the new species, as well as an updated key for the genus Prosopanche. In addition, we identified that P. cocuccii produces a large number of rhizomes and fruits for each single host specimen of tobacco (Nicotiana tabacum), which resulted in a decrease in height and growth of its only known host plant.

Abstract

Derris rubricosta Boonprajan & Sirich., sp. nov., a new species of the genus Derris Lour. (Fabaceae) was discovered in Peninsular Thailand. The overall morphology demonstrates that the species most resembles D. pubipetala. Nevertheless, the species has several autapomorphies differentiating it from other Derris species, e.g., the presence of reddish midribs of the mature leaflets, sparsely hairy stamen filaments, prominent hairs at the base of the anthers, and presence of glandular trichomes along the leaflet midrib. Additionally, HPLC fingerprints of this species showed a distinction from D. pubipetala by the absence of phytochemical compound peaks after 13 min. Retention Time (RT). Results from molecular phylogenetic analyses also strongly supported the taxonomic status as a new species.

 Derris rubricosta Boonprajan & Sirich., sp. nov.

 

Diagnosis: The species has several autapomorphies distinguishing it from other Derris species. It is the only species that has reddish midribs on the lower surface of mature leaflets. Its style is sericeous at the base and gradually becomes glabrous apically (vs. thinly hairy at the base and mostly glabrous throughout in other Derris species). Derris rubricosta has prominent hairs below the anthers (vs. glabrous anthers in all other Derris species). It is morphologically similar to D. pubipetala Miq., but differs by its leaflet midrib colour (reddish vs. green), number of leaflets or leaf (9–11 vs. 5–9), colour of its corolla (pale pink to pink vs. white), wing petal margin (straight vs. revolute), stamen filament indumentum (sparsely hairy vs. glabrous), indumentum presence below the anthers (present vs. absent), floral disc shape (indistinct to more-or-less 10-lobed vs. annular).

Etymology: The specific epithet refers to the striking reddish colour of the midrib of the mature leaflets which has never been found in other species of Derris.

Vernacular names: “Khruea lai leeratiwong” (เครือไหลลีรติวงศ์) means “Leeratiwong’s Derris”, in Thai, in honor of Associate Professor Dr. Charan Leeratiwong, who discovered and collected the type specimens.

Distribution: Peninsular Thailand: Songkhla (Rattaphum district, Sadao district) (Fig. 4). Estimated population of more than 2,500 mature individuals were found during field survey between 2019 and 2022 in its type locality and nearby areas.

Abstract

Within the isophyllous group of Campanula ser. Garganicae, represented by species of prevalent Adriatic and Ionian distribution, a rare new endemic species named C. cremnophila is described and illustrated from Pelješac Peninsula and the nearby Elaphite islands of Olipa and Jakljan (southern Croatia). It is a chasmophyte growing on calcareous rocky crevices near the sea, showing close relationship with C. garganica from southern Italy. Phylogenetic analyses based on nuclear ITS and chloroplast trnL–trnF data emphasized that C. cremnophila is distinct from other species of this group, forming a subclade with C. garganica and C. poscharskyana. The morphology, SEM microstructure of seeds and pollen grains, taxonomical relationships, ecology, conservation status of C. cremnophila, as well as an identification key including the species of the ser. Garganicae, are provided.

Abstract

Cyrtandra obliquifolia K.R. Wood & W.L. Wagner (Gesneriaceae), a new shrub species known only from Kaua‘i, Hawaiian Islands, is described and illustrated with notes on its distribution, ecology, and conservation status. The new species is morphologically most similar to Cyrtandra wawrae C.B. Clarke but differs by its unique combination of oblique, non-peltate, auriculate leaf bases, more deeply divided calyx lobes, inflorescence with fewer flowers and lacking profusely umbellate cymes. Cyrtandra obliquifolia is known from only two localities which have undergone severe habitat degradation from landslides and invasive plants and animals and is determined to be Critically Endangered (CR) when evaluated under IUCN criteria.

Key words: Conservation, critically endangered, Cyrtandra, Gesneriaceae, Hawaiian Islands, Kaua‘i

Diagnosis: Morphologically, Cyrtandra obliquifolia is similar to C. wawrae, differing in having non-peltate leaves (vs. peltate), only 3–5-flowered cymes (vs. dense umbelliform cymes up to 17-flowered), corolla tube 10–11 mm long (vs. 13–17 mm long), and calyx ca. 10 mm long, the lobes lanceolate, 8–9.5 mm long, pilose within (vs. calyx 12–32 mm long, enclosing the fruit at maturity, the lobes deltate, 2–6(–10) mm long, glabrate to sparsely pilose).

Etymology: The species epithet is from the Latin obliquus meaning slanting or unequal sides, and folius for leaf.

[Botany • 2024] Ardisia chimingiana (Primulaceae) • A New Species from Yunnan, China

Ardisia chimingiana Y.H. Tan & D.L. Quan,

DOI: 10.5735/085.061.0102

Abstract

Ardisia chimingiana Y.H. Tan & D.L. Quan, sp. nova (Primulaceae) from Yunnan, China, is described and illustrated. It belongs to the subgenus Tinus and has long been misidentified in China as A. solanacea and A. polycephala due to similarities in leaf blades and inflorescences. However, it differs from those two species by having fewer leaf veins, inflorescences with fewer flowers, shorter peduncle, glabrous calyx margin, and fruits not turning black. We discuss the morphological distinctions of A. solanacea and a few other similar species. A lectotype is designated for A. solanacea.
