Abstract

A new species, Microlicia almedae, is described and illustrated from the species-rich campo rupestre vegetation of Chapada Diamantina, Bahia, Brazil. The taxonomic novelty is morphologically related to M. giuliettiana and M. pulchra, which are also restricted to Chapada Diamantina. Microlicia almedae differs from the latter two species in leaf shape and size, hypanthium indumentum, calyx lobe shape and size, and petal size. In addition, M. almedae differs from M. giuliettiana by its uniformly magenta petals and from M. pulchra by its capsules with deciduous columellae. Variation in leaf shape among M. almedae, M. pulchra, and M. giuliettiana was quantified using elliptic Fourier analysis, which revealed near-complete separation among the three species.

Abstract

Begonia thanhquyetii, a new species from central Vietnam, is herein described and illustrated. It is morphologically most similar to B. baik in its creeping habit, rugose ovate leaves, and protogynous inflorescences. However, it differs in several key morphological characters, including stipules hirsute on the abaxial surface (vs. glabrous), bracts lacking glandular hairs along the margins (vs. glandular-ciliate), a pair of bracteoles present near the apex of the pistillate pedicel (vs. bracteoles absent), abaxial tepals of both staminate and pistillate flowers hirsute (vs. glabrous), and densely hirsute ovary (vs. glabrous). Following the IUCN Red List Categories and Criteria (Version 16), B. thanhquyetii is provisionally assessed as Least Concern (LC), pending further field surveys to clarify its distribution and population status.

Abstract

Ceropegia gengmaensis P.R.Luo, A.Liu & H.Sun, a new species from Gengma County, Yunnan, Southwest China, is described. Both morphological characteristics and chloroplast phylogenetic analysis strongly support its placement within C. sect. Chionopegia H.Huber. Molecular data further reveal that C. gengmaensis is closely related to C. salicifolia, C. mairei, and C. dolichophylla, yet it can be distinguished from them readily by its stem indumentum, leaf shape, and floral morphology, particularly the shape of the corolla tube, and features of the lobes. A detailed line drawing of this new species is also provided.

Diagnosis. Ceropegia gengmaensis shows affinities with C. salicifolia and C. dolichophylla, both of C. sect. Chionopegia . It differs from C. salicifolia by its erect to sprawling habit (vs. twining), elliptic leaves 2.0–5.5 cm (vs. lanceolate, 6–15 cm), densely pubescent stems bearing usually solitary flowers (vs. glabrous stems with sessile cymose many-flowered inflorescences), and narrower corolla lobes with only slight expansion above the throat (vs. lobes longer and wider, upper portion markedly expanded). From C. mairei it differs by the much less pronounced basal inflation of the tube (vs. a strongly inflated tube) and ... 

Etymology. Ceropegia gengmaensis is named after its type locality, Gengma County, Southwest Yunnan.

Vernacular name. the Chinese name is given as “耿马吊灯花” (gěng mă diào dēng huā) named after the type locality, Gengma County, Southwest Yunnan.

Abstract 

The goblin spider genus Orchestina Simon, 1882 (Araneae: Oonopidae) in Japan has been revised, recognizing nine species including two new species and four species newly recorded from Japan: O. okitsui Oi, 1958 (♂♀), O. flava Ono, 2005 (♂♀), O. sanguinea Oi, 1955 (♀), O. saaristoi Henrard & Jocqué, 2012 (♂♀, new record), O. saltitans Banks, 1894 (♂♀, new record), O. colubrina Liu, Henrard & Xu, 2019 (♂, new record), O. pavesii (Simon, 1873) (♂♀, new record), Orchestina nojimai sp. nov. (♀) and O. insulana sp. nov. (♀). A literature survey revealed errors in the correspondences between figures and captions in a pictorial book, which likely led to the misidentification of the synanthropically introduced species O. saltitans as the forest-dwelling native species O. okitsui. The misrepresentation also gave rise to the erroneous assumption that the male of O. sanguinea had been described, although no male specimen has actually been reported. In addition, Orchestina flagella Saaristo & van Harten, 2006, is here synonymized with O. saltitans (O. flagella syn. nov.). This study provides photographs and illustrations of nine Orchestina species, including the type specimens of O. okitsui, O. flava and O. sanguinea, notes on their habitats, distribution maps, supplemental molecular data, and a graphical character matrix of Orchestina species in Japan.

[Botany • 2018] Lobelia hongiana (Campanulaceae) • A New Species from Guangxi, China

Lobelia hongiana Q.F.Wang & G.W.Hu, 

in Li, Wei, Liu, Chen, Hu et Wang, 2018.

 DOI: doi.org/10.3897/phytokeys.95.20245

Abstract

Lobelia hongiana, a new species of Campanulaceae from Guangxi, South China, is described and illustrated here. This new species is most similar to L. chinensis and L. loochooensis, but differs by its elliptic-obovate or oblanceolate leaf, 2.5–3 mm long greenish-carmine hypanthium, 5 or 6 calyx lobes, purplish-white corolla, with yellowish-green blotches at the base of lower lobes, glabrous filaments, 7–8 mm long broadly obconic capsule. Molecular phylogenetic analysis has been conducted based on ITS and two chloroplast sequences (atpB and rbcL) and 14 taxa in Lobelia are included. L. hongiana is well supported as a new species by the evidence from both morphology and molecular phylogeny.

Keywords: Hypsela, Lobelia chinensis, Lobelia loochooensis, Southern China

Lobelia hongiana Q.F.Wang & G.W.Hu, sp. nov.

Diagnosis: The new species is distinguished from L. chinensis and L. loochooensis by its elliptic-obovate or oblanceolate leaves, usually sinuate-dentate margin; hypanthium 2.5–3 mm long, greenish-carmine; calyx lobes 5 or 6, shorter than hypanthium; corolla purplish-white, yellowish- green blotches at the base of lower lobes; glabrous filaments; broadly obconic capsule, 7–8 mm long; flowering time from May to July.

 

Distribution and ecology: The new species has been found in Huixian Wetland, Guangxi Zhuang Autonomous Region in China, with only two populations. There is a high probability that L. hongiana is also distributed at adjacent areas, given its vegetative propagation traits. Its living environment is wetland and farmland.

Phenology: The new species was found in flower from May to July.

Etymology: Species epithet, “hongiana”, is in honour of Prof. De-Yuan Hong who made a significant contribution to the authors’ knowledge of Campanulaceae.

Abstract

Oreocharis sihuiensis sp. nov. (Gesneriaceae) is described from Guangdong Province, China. Morphologically, the flower shape of this new species is similar to that of O. dayaoshanioides, but it can be distinguished by its leaf blade being adaxially densely pubescent, with hairs 0.2–0.5 mm long (vs. adaxially sparsely villous to villous, with hairs longer than 1 mm), lobes of the corolla upper lip subrounded and apex rounded (vs. broadly ovate to orbicular-ovate and apex acute), 3 staminodes (vs. absent or 2), disc margin cleft (vs. subentire), shorter filaments (ca. 6.0 mm long vs. 8.0–12.0 mm long), and shorter capsules (ca. 1.0 cm long vs. ca. 2.0 cm long). Considering its scarce number of individuals, and the presence of severe human disturbance, we preliminarily assess the new species as ‘Critically Endangered’ (CR) according to IUCN Red List Categories and Criteria.

Abstract

We present a morphological description of a recently discovered species of spider in the family Trogloraptoridae from the Columbia River Gorge in northwestern Oregon. The family was previously monotypic (Trogloraptor marchingtoni) and only known from populations near the southwestern Oregon—northern California border. Trogloraptor tulishpun sp. nov. retains the key family synapomorphy, distinctive subsegmented raptorial tarsi, and an oblique membranous division of the basal segment of the anterior lateral spinnerets. Trogloraptor tulishpun is distinguished from T. marchingtoni by its color pattern, clypeal height, vulvar and palp structure. We have found T. tulishpun in four localities in the Columbia River Gorge, which show little mitochondrial sequence divergence from one another, but are highly genetically distinct from T. marchingtoni. Trogloraptor tulishpun is found in basalt features, including lava tubes and shallow talus caves, and has been observed to eat arachnids and moths, making them top predators in these environments.

Trogloraptor tulishpun, Jones and Binford, sp. nov.  

Diagnosis. Trogloraptor tulishpun resembles T. marchingtoni (Griswold et al., 2012) by its similar carapace and abdominal shape and coloration, its subsegmented raptorial tarsi, and the partly sclerotized genital region (Figs 2, 3, 5, 7). It is clearly distinguished by its conspicuous scalloped patterning along the lateral and posterior edges of the carapace which is absent in T. marchingtoni. The abdominal patterning is different from the chevron pattern of T. marchingtoni, with oval-shaped spots down the center of the dorsal side that have a thin line of beige down the ...

Etymology. Tulishpun (pronounced too-lish-pun) is a word, simplified for ease of pronunciation, from the Sahaptin River dialect meaning “cave predator, owner of the domain”. The Sahaptin River dialect is from the Columbia River area, the type locality of this species, and the name was given to us by elders from the Columbia River Inter-Tribal Fish Commission. The specific epithet is to be treated as a noun in apposition.

Abstract

Gravesia gautieri, a new species from northern Madagascar, is described, illustrated, mapped, and compared with presumed relatives based on morphological characters. It is readily diagnosed by its sparingly branched suffrutescent habit, 3-nerved leaf blades that are coarsely and remotely serrate at least distally with a sparse cover of minute brown granular hairs and ± appressed smooth hairs abaxially, long-pedunculate umbellate inflorescences, ± terete and ecostate hypanthia, obsolete calyx lobes with callose-thickened teeth borne on and barely exceeding the calyx tube in length, and dorso-basal subulate staminal appendages that are deflexed to variously coiled.

Abstract 

Cryptoclidia (Plesiosauria, Plesiosauroidea) was a major clade of marine reptiles that originated during the Jurassic. The early evolution of Cryptoclidia is documented by records of Cryptoclididae from the Middle Jurassic (174.7–165.1 Ma) and onwards in Europe, the Caribbean and South America. However, the origin of Cryptoclidia itself has remained obscure. Only some traits shared with Cryptoclidia are found in the Toarcian (184.2–174.7 Ma) taxa Plesiopterys wildi and Franconiasaurus brevispinus, from southern Europe. Here we describe a small-bodied sub-adult skeleton belonging to a new plesiosaurian taxon from the Middle Jurassic (c. 170 Ma) of the Atacama Desert (former southwestern Gondwana). The new taxon has single-headed ribs in its axial skeleton, and its combination of novel and ancestral features place it as the sister taxon of Cryptoclidia. The lower Bajocian stage, the phylogenetic position of the new taxon, as well as its palaeogeographic occurrence, point to an older origin and dispersal of Cryptoclidia ancestors, reinforcing the notion that an early Caribbean corridor between the Pacific and Tethyan realms was already functional during the Middle Jurassic.

The genus Syngonium is represented in Mexico by ten species, seven of which are registered for the state of Chiapas. During fieldwork between 2020 and 2025 in Berriozabal, Chiapas, we discovered an undescribed species of Syngonium sect. Syngonium that is morphologically similar to S. neglectum, but differing from that species in having one or two inflorescences per axil, glaucous stems and spathe tube, a spathe blade almost twice as long as the staminate portion of the spadix, staminate flowers retuse at the apex, glaucous immature infructescence and the spathe not persistent in mature fruits.
