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.

Abstract

The present study reports a new species, Pseudocapritermes novus Rituparna, Baraik & Rajmohana sp. nov. from West Bengal, India. Species description followed an integrative taxonomic approach by including a mitochondrial 16S rRNA genetic sequence with comprehensive morphological characteristics of the soldier caste. Additionally, the first mt 16S rRNA gene sequence for the recently identified Pseudocapritermes kunjepu Mathew, 2020, is presented in the study. Digital photos of the new species are also included, along with an identification key to the soldier castes of all species of the genus reported from the Indian sub-continent. Association of Pericapritermes semarangi (Holmgren, 1913) with the new species is also recorded in the study.

[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.

斌源似丛柳珊瑚  ||  DOI: doi.org/10.3390/d18030166 

Abstract

A new shallow-water gorgonian coral species in the family Acanthogorgiidae, Paraplexaura binyuani sp. nov., is described from a specimen collected at Huaguang Atoll in the South China Sea at a depth of 22 m. The new species is distinguished from its congeners by abundant polyp sclerites, predominantly flattened rods, and by the coenenchyme bearing numerous large spindles reaching up to 0.6 mm in length, which are approximately two to three times longer than those reported for most described species of Paraplexaura. Phylogenomic analyses based on ultraconserved elements (UCEs) recover Paraplexaura as monophyletic and place P. binyuani sp. nov. as sister to P. cryptotheca, consistent with its morphological distinctiveness and supporting its recognition as a separate species.

Newmania bambusifolia Škorničk., Vuong & Bao, sp. nov. 

Unique in the genus by its prominently narrow, bamboo-like leaf-blades and dark purple labellum with overlapping lobes. Flowers are most similar to Newmania cristata by the yellow to greenish floral tube and filament, but differ by having a small anther crest less than 1 mm long with entire rounded apex (vs anther crest 4.6–5 mm long with a bilobed apex).

Etymology. The specific epithet refers to the unusually narrow, bamboo-like leaf blades.

Abstract

Archosauriformes comprise a diverse range of reptiles, including the crown-group Archosauria, which flourished during the Triassic Period. Early-diverging archosauriforms, such as proterosuchids and erythrosuchids, are becoming progressively well-known due to recent studies and consistently resolve at the base of the clade. More crownward, Eucrocopoda includes archosauriform taxa that increasingly approximate the ancestral archosaur body plan. Early-diverging eucrocopodan archosauriforms have a widespread paleogeographic record but remain poorly understood in terms of ingroup relationships. Within this radiation, Euparkeriidae is particularly challenging, because its ingroup composition and monophyly is debated, with some authors supporting a non-monospecific Euparkeriidae, whereas others fail to recover this hypothesis. The eponymous Euparkeria capensis is known from the Early to Middle Triassic of South Africa, whereas other putative euparkeriids are primarily known from the Early to Middle Triassic of China, Germany, Poland, and Russia. Here, we describe a new early-diverging eucrocopodan (Silescelida acristata gen. et sp. nov.) from the Middle Triassic of southern Brazil. Phylogenetic analyses incorporating this taxon suggest a possible placement within Euparkeriidae, though its position shows instability depending on the operational taxonomic units considered, especially among other putative euparkeriids. This discovery not only informs on the temporal and paleogeographic distribution of euparkeriids but also sheds light on the origin and early evolution of eucrocopodans, representing the first record of this archosauriform grade in the Triassic of Brazil. More broadly, the new taxon underscores the significance of South American Triassic deposits within the evolutionary history of archosauriforms.

Holotype. MCP 4186-PV, a left scapula, a right ilium, and a left femur (Fig. 1C, D). The elements were found in association (attached to each other) and are size-compatible; therefore, they are considered to belong to the same individual.

Type locality, age, and horizon. Posto (or Posto de Gasolina; Fogliarini) site (29°37’38.9”S 53°22’06.5”W), municipality of Dona Francisca, Rio Grande do Sul, Brazil (Fig. 1A, B).

Diagnosis. The holotype of Silescelida acristata differs from all other known non-archosaurian archosauriforms in the following combination of traits: scapular blade without an anteroposterior constriction at its base; asymmetrical expansion of the scapular blade at its dorsal portion; straight posterior margin of the scapular blade, forming a right angle with the dorsal margin of the glenoid; elliptical tuber for the m. triceps dorsal to the glenoid; dorsal margin of the dorsal iliac blade straight in dorsal and lateral views; dorsal iliac blade as deep as the acetabulum; notch between the ischiadic peduncle and the ventral apex of the medial acetabular wall; medially expanded femoral head; absence of a longitudinal groove on the proximal surface of the femoral head; posteromedial tuber as the only well-developed tuber on the femoral head; absence of an elevated mound or crest-like structure as the attachment site for the m. caudofemoralis (local autapomorphy); extensor fossa on the anterior surface of the femoral distal end; distal femoral condyles with the same degree of ventral development (not uneven).

Etymology. The generic name combines the Latin siles (“silence”) and the Greek skelēs (“hind leg”), referencing the loss of the proximal femur bearing the specimen’s collection code, which obscured its provenance until its recent rediscovery. The specific epithet derives from the Latin prefix a- (“without”) and cristāta (“crested”), referring to the absence of a crest or flange attachment site for the m. caudofemoralis (= fourth trochanter), a diagnostic feature of the taxon.

Abstract

Kongobatha is one of the most commonly encountered of all Australian mantis genera, and yet despite this, very little is known about the taxonomy or biology of the genus. Described to include a single Australian species, K. diademata, the only subsequent work on the genus has been the description of a second species from New Guinea, K. papua. We here describe three additional species, K. spinosistyla Connors sp. nov., K. serpens Connors sp. nov., and K. rufilinea Connors sp. nov., and redescribe K. diademata and K. papua in detail, the latter of which is recorded from Australia for the first time. We also describe for the first time the unusual, heavily spinose styli of male Kongobatha. These are apparently unique among Mantodea as a whole, but their function remains unknown.
