Abstract

Identified as Gardenia over a century ago, three known species from Thailand to south China differ considerably from typical members of that genus, from which growth habits, aspects of branch architecture and corolla shape set them apart. They form a new genus, here named Thaigardenia, the species of which are scrambling to thicket-forming shrubs to sometimes treelets or small trees. They have typically unequal (asymmetric) development of each internode that offsets what began as opposite pairs of axillary buds (and potential axillary branches) from subtending leaf axils at the same level, and small infundibular corollas with insignificant tubular bases. In contrast, typical Gardenia are non-scrambling shrubs or trees, often have extra-axillary buds or branches that consistently continue to develop at the same level (i.e., remaining opposite); and showy hypocrateriform (salverform) corollas with elongate tubular bases. The unequal development of different sides of an internode that brings an initially opposite pair of axillary buds (branches) to different levels, so that they do not appear paired subsequently, is, as far as is known, unique and unknown in other Rubiaceae or opposite-leaved plants; this shared feature is a key synapomorphic character for species of the newly recognised genus.

Thaigardenia Sungkaew, Teerawat., Chamch. & K.M.Wong, gen. nov.

Thaigardenia is a new genus of the Rubiaceae, allied to Gardenia J.Ellis, differing in the species being shrubs with a scrambling to thicket-forming habit or small trees with crooked sympodial trunks (vs Gardenia s.s. which are mostly trees with monopodial trunks or non-thicket forming bushes), developing extra-axillary buds and branches at different distances from a leaf-pair at the same node on stems and branches (sometimes these extra-axillary buds more than one per leaf axil) (vs with extra-axillary buds and branches always at the same level, and solitary buds in Gardenia), broad-triangular stipules fused along their edges (vs typical Gardenia spp. with stipules fused into a cylindric sheath split slightly on one side), infundibular corolla with insignificant tubular bases much shorter than the inflated upper portion (vs hypocrateriform corollas with relatively long basal tubes with a hardly widened uppermost portion in Gardenia), and pollen issued as tetrads. 

Type: Thaigardenia collinsiae (Craib) K.M.Wong, Teerawat. & Sungkaew.

Etymology.— The name Thaigardenia refers to Thailand, where studies into the taxonomy of this group were initiated, and where the generic type can be abundantly found, as well as Gardenia, the genus in which its species were earlier placed. Thailand has been eponymously included in the nomenclature of two other plant genera: Thaia Seidenf. (Orchidaceae) (Seidenfaden, 1975) and Thailentadopsis Kosterm. (Leguminosae) (Kostermans, 1977), both of which continue to be in use (Lewis & Schrire, 2003; Xiang et al., 2012).

Abstract

A novel endemic pest of clove tree, Cryptophasa warouwi sp. nov., has been discovered on Sangihe Island. This new species can be distinguished from its closest relative species, C. watungi Sutrisno & Suwito, 2015 which is found in North Sulawesi, by its dark brown straw-coloured wings in both males and females. The most distinctive diagnostic characters of this new species are observed in its genitalia structure: a bent-downward uncus with a strongly sclerotized finger-shaped apex, a bent phallus gradually widened towards coecum, and a double, membranous corpus bursae branching off at mid-ductus corpus bursae of female genitalia. Additionally, DNA barcodes revealed this new species to be embedded among Australian Cryptophasa species despite having fasciculated male antennae that have been considered diagnostic of the genus Paralecta. This suggests that the male antennae may not be a reliable character for separating Cryptophasa from Paralecta. A more comprehensive study including all Cryptophasa and Paralecta will be required to elucidate the definition of each genus. Images depicting both adults and genitalia are provided for this newly recognized species.

Cryptophasa warouwi Sutrisno & Watung, sp. nov.

Diagnosis. The male of C. warouwi sp. nov. is easily distinguished from the closest species, C. watungi , by the forewing dark brown streak along the entire costa, which is gradually paler towards CuP, being light brown from CuP towards dorsum, the dark brown spots on discal cell of forewing, predominantly dark brown and become paler from the cubito-anal (CuA 1 and CuA 2) area towards dorsum, and white on the discal cell of hindwing. The female has the forewing with a white ochreous ground color tinged with brown from costa to dorsum, more pronouncedly so toward the margin, with a dark brown spot at the discal cell, a margin with a prominent basal line of alternating white and dark brown dashes (Fig. 1C–D). A bent-down uncus (black arrow) with a strongly sclerotized, finger-shaped apex (black arrow) a slightly sclerotised, medially bent phallus (black arrow), and a double corpus bursae without signum black arrow) are the best diagnostic for the male and female genitalia of this species (Fig. 2C–D, 3B).

Etymology: The species name is dedicated to Dr. Ir. Jootje Warouw, a senior entomologist and retired professor in the Faculty of Agriculture, Sam Ratulangi University who conducted research on pest control in Sangihe and Talaud Islands.

Abstract

This study provides detailed description of a newly-discovered Callicarpa yongshunensis Wen B. Xu, Xiao D. Li & Yan Ling Liu (Lamiaceae) species from Hunan, China. The species shares similarities in the inflorescence, glandular colour and leaf shape features with C. luteopunctata H. T. Chang and C. giraldii Hesse ex Rehd., while its white fruits are similar to those of C. longifolia Lamk. However, its procumbent, evergreen shrub and white fruits are distinctly different from those of C. luteopunctata and C. giraldii, while its procumbent, scarless nodes and stellate pubescence free fruits distinguishes it from C. longifolia. Images, distribution, morphological features, molecular phylogenetic classification and conservation assessment of this new Callicarpa species are explored.

Abstract

We report a new species, Oxynoemacheilus fatsaensis, from the Elekçi Stream, a small stream that flows to the Black Sea in Northern Turkey. It is distinguished from other Oxynoemacheilus species in the Black Sea, Upper Euphrates, and Kura-Aras River basins by having a suborbital groove in males, an axillary lobe at the pelvic-fin base, no dorsal adipose crest on the caudal peduncle, a deeply emarginate caudal fin, small inner and outer rostral barbels, and mottled flank pattern. Molecular data suggest that the new species is separated by a minimum p-distance of 3.3% from O. banarescui in the mitochondrial DNA COI barcode region.

Cave loaches within the family Nemacheilidae are among the most diverse group of cavefish in southwestern China. Although certain species have been included in previous phylogenetic studies, the intergeneric and interspecific relationships of Chinese cave loaches in Nemacheilidae remain poorly investigated due to insufficient sampling. In this study, a total of 45 samples from 37 recognized species and two unidentified species of cave loaches were collected, accounting for 87.5% of the eight recognized genera of cave loaches within the family Nemacheilidae in China. The complete mitochondrial genome (mitogenome) and seven nuclear genes were sequenced, and the phylogenetic tree of Chinese cave loaches was reconstructed. Both Bayesian inference and maximum-likelihood analyses resolved the phylogenetic relationships at the generic and species levels, suggesting the effectiveness of this multilocus marker system in determining phylogenetic relationships in Chinese cave loaches. Phylogenetic analysis not only confirmed previous taxonomic hypotheses based on morphological data but also provided new insights into the relationships of many cave loaches at the genus and species levels as well as suggestions for the current taxonomy of cave loaches within the family Nemacheilidae.

The karst regions of southwestern China are considered the center of Chinese cavefish biodiversity, boasting the most concentrated distribution of cavefish in the world. However, many cavefish species in the region remain poorly known and highly threatened (IUCN, 2022). Nemacheilidae, which contains approximately 22 genera and 269 species, constitutes one of the largest and most diverse families, second only to Cyprinidae in terms of diversity (Zhang et al., 2020). These cave loaches, which include both stygophilic and stygobitic species, are restricted in their distribution to the karst regions of southwestern China and exhibit highly specialized morphologies (Lan et al., 2013; Li, 2018). This has led to inadequately resolved taxonomies and enigmatic phylogenetic relationships among cave groups. The presence of both subterranean and surface-dwelling phenotypes among these genera, as well as the influence of convergent evolution, make it challenging to distinguish them based on morphological characteristics alone. The classification of Chinese cave loaches has been the subject of debate, ...

  

Karstsinnectes Zhou, Luo, Wang, Zhou & Xiao, gen. nov.

Type species: Oreonectes anophthalmus Zheng, 1981.

Diagnosis: (1) body naked, scaleless, and body color pattern absent; (2) eyes absent; (3) lips with furrows but no papillae; (4) anterior and posterior nostrils slightly separated, anterior nostril tube long, without elongated short barbel-like tip; (5) without longitudinal stripe; (6) dorsal fin with 7 branched rays, dorsal-fin origin slight posterior to ventral-fin origin; (7) caudal fin forked or rounded, caudal peduncle with adipose crests; (8) cheeks scaleless; (9) lateral line and cephalic lateral-line canals present; (10) bony capsule of swim bladder open posteriorly.

Etymology: The genus name Karstsinnectes is a combination of words. Karst is an English word meaning an area of water-eroded limestone; sin is an abbreviation of the Greek word Sino, refers to Chinese; nectes, a Greek word meaning swimmer. We suggest its English common name “Chinese Karst Loach Genus” and Chinese common name “Zhōng Huá Kā Qiū Shǔ (中华喀鳅属)”.

Distribution: Currently, this genus includes four species, i.e., Karstsinnectes acridorsalis (Lan, 2013) comb. nov., Karstsinnectes anophthalmus (Zheng, 1981) comb. nov., Karstsinnectes hyalinus (Lan, Yang & Chen,1996) comb. nov., and Karstsinnectes parvus (Zhu & Zhu, 2014) comb. nov., all of which distributed in the Hongshuihe, Zuojiang, and Youjiang river basins in Guangxi, China.

ABSTRACT

A new, possibly, infaunal species of the genus Potamalpheops Powell, 1979 (Crustacea: Decapoda: Alpheidae), Potamalpheops kisi sp.n., is described from the intertidal mangrove swamps of the Can Gio Mangrove Biosphere Reserve, South Vietnam. The new species clearly belongs the “P. monodi” species group, but can be easily separated from related species (P. pininsulae Bruce et Illife, 1992, P. tigger Yeo et P.K.L. Ng, 1997 and P. johnsoni Anker, 2003) by the length and shape of rostrum, the length and proportions of carpus and palm of pereiopods I and II, as well as some other minor morphological features. All individuals of the new species were pumped out of burrows in anoxic swamp mud, while no individuals were collected using a hand net during extensive sampling in the same habitats, suggesting that the new species inhabits in a burrow system. No evidence of relationship to any host species is available, since individuals of the new species were collected from different burrows and never with syntopic larger burrowing animals. Observations in situ at nighttime revealed that individuals of Potamalpheops kisi sp.n. freely move inside burrows located above the water level, similar to other mangrove semi-terrestrial shrimp Merguia oligodon, which possibly allows surviving in anoxic conditions of swamp soils; such behavior is described for the genus Potamalpheops for the first time.

Species descriptions of reptiles historically have relied exclusively on the use of morphological data; however, these external, phenotypic data do not always co-vary with lineage divergence. Consequently, it has become increasingly clear that species diversity has been underestimated in many evolutionary radiations. With the use of an integrative approach, we examined the genetic and morphological diversity present in a nearly endemic Philippine radiation of Eutropis. Results demonstrated that current taxonomy does not reflect evolutionary history and that in many cases, morphological divergence has become decoupled from genetic divergence. As a consequence, species diversity is significantly underestimated. Here, we rectify the major taxonomic problems present in Philippine Eutropis by providing formal descriptions for eight new species. Three of the four new species in the E. multicarinata species complex are sympatric with (and have long been confused with) previously described subspecies (which we also elevate to full species here). The fourth species is endemic to the Caroline Islands, clearly derived from a long-distance dispersal event from the Philippines. The new species in the E. indeprensa species complex are allopatrically or parapatrically distributed across the archipelago. In contrast to the last review of Philippine Eutropis, which suggested the endemic radiation was composed of five species (one of which was composed of two subspecies), we demonstrate that this group includes at least 14 distinct evolutionary lineages, with potential for additional diversity to be discovered pending further study.

Abstract

Five new species, Anisandrus montanus sp. nov., A. phithakpa sp. nov., A. tanaosi sp. nov., A. triton sp. nov., and A. uniseriatus sp. nov. are described from Thailand. Anisandrus carinensis (Eggers, 1923) is reported from Thailand for the first time and A. apicalis is removed from the Thai fauna. With the inclusion of the species described and recorded here, the diversity of Anisandrus is increased to 40 species, of which 11 occur in Thailand. A synoptic list and a key to the Anisandrus of Thailand are presented.

Key words: Key, new records, Oriental region, Thai fauna
