A new species, Bredia malipoensis D. H. Peng, S. Jin Zeng & Z. Y. Wen, from China, is described and illustrated here. Bredia malipoensis is morphologically similar to B. longiradiosa C. Chen in having cordate leaf blades, umbellate inflorescence and undulate petals with unguiculate bases and retuse apices. It is characterized by its terete stem and petioles, green calyx lobes, purple anthers, yellow connective appendages and white filaments. It is also morphologically similar to B. velutina Diels in having a woody stem, unequal and cordate leaf blades, but it is differentiated by having no reddish trichomes, larger and semiorbicular calyx lobes, and unguiculate petal bases. Bredia malipoensis differs markedly from the former relatives by its densely tomentose indumentum (with uniseriate non-glandular and sparse glandular trichomes) both on vegetative and floral parts, basal leaf venation and purplish-red petals. Our phylogenetic analyses using nuclear ribosomal ITS and chloroplast trnV-trnM regions strongly support the generic placement of B. malipoensis and its relatives B. longiradiosa and B. velutina within Bredia.

A new species, Rariglanda jerseyensis, is described from well-preserved fusainized fossil flowers collected from the Late Cretaceous of New Jersey. Phylogenetic analyses and comparisons with extant and extinct taxa place R. jerseyensis within the monophyletic Ericales, sister to Clethraceae. The most distinctive feature of R. jerseyensis is a dense covering of conspicuous multicellular trichomes on the abaxial surface of the calyx. These multicellular trichomes appear to be glandular, and similar trichomes are found in several other, unrelated, Late Cretaceous fossils. In particular, the ericalean fossil Glandulocalyx upatoiensis bears the most similarity to R. jerseyensis, although differences in androecium and trichome characters clearly separate the two taxa. In addition, phylogenetic analyses confirm the position of G. upatoiensis within the Ericales, but place it within the sarracenioid clade, in a polytomy with Actinidiaceae and Roridulaceae. Past ecological studies associating trichomes with defense against herbivores and pathogens, coupled with the prevalence of multicellular trichomes on flowers among different lineages of fossils in the Cretaceous, suggest that glandular trichomes could have been an important adaptation against herbivore feeding during the Cretaceous.

Summary A new species of entomopathogenic nematode, Steinernema borjomiense n. sp., was isolated from the body of the host insect, Oryctes nasicornis (Coleoptera: Scarabaeidae), in Georgia, in the territory of Borjomi-Kharagauli. Morphological characters indicate that the new species is closely related to species of the feltiae-group. The infective juveniles are characterised by the following morphological characters: body length of 879 (777-989) μm, distance between the head and excretory pore = 72 (62-80) μm, pharynx length = 132 (122-142) μm, tail length = 70 (60-80) μm, ratio a = 26.3 (23.0-29.3), H% = 45 (40-51), D% = 54 (47-59), E% = 102 (95-115), and lateral fields consisting of seven ridges (eight incisures) at mid-body. Steinernema borjomiense n. sp. was molecularly characterised by sequencing three ribosomal regions (the ITS, the D2-D3 expansion domains and the 18S rRNA gene) and the mitochondrial COI gene. Phylogenetic analyses revealed that S. borjomiense n. sp. differs from all other known species of Steinernema and is a member of the monticolum-group.

A new species of the Cyrtodactylus irregularis group is described from Ninh Thuan Province, southern Vietnam based on molecular divergence and morphological differences. Cyrtodactylus orlovi sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by having the unique combination of the following characters: size medium (SVL 61.0–77.7 mm); dorsal tubercles in 16–20 irregular rows; 36–39 ventral scale rows; precloacal pores absent in females, 5 or 6 in males, in a continuous row; femoral pores absent; 3–8 enlarged femoral scales; postcloacal spurs 1 or 2; lamellae under toe IV 16–19; a continuous neckband; a highly irregular transverse banded dorsal pattern; the absence of transversely enlarged median subcaudal scales. In phylogenetic analyses, the new species was revealed to be the sister taxon to a clade consisting of Cyrtodactylus cattienensis and the most recently described species from Vietnam, C. chungi, with 12.1–12.4% and 11.7 % pairwise genetic divergence from the two species, respectively, based on a fragment of the mitochondrial COI gene.

Tigridiopalma longmenensis, a new species from Guangdong, China, is described. This species differs from its ally, T. magnifica, by the polychasium consisting of scorpioid cymes, hypanthium with carinas on angles, and longer stamens with a conspicuously white or pink spur at the connective base of anther. A diagnosis and a distribution map of the two species are also provided. The complete chloroplast genome of T. longmenensis was reported here. Phylogenetic analyses based on complete chloroplast genomes from T. longmenensis and other 15 Melastomataceae species indicated that T. longmenensis is sister to T. magnifica. The discovery of T. longmenensis terminates Tigridiopalma as a monotypic genus.

An adult sand snake specimen was collected during a herpetofaunal survey conducted in the Turpan Basin in northwest China. Phylogenetic analyses revealed that this specimen, along with other snake sloughs and skins collected from different localities in the Turpan Basin formed a clade that is sister to Psammophis lineolatus. This taxon exhibited substantial divergence from its congeners (P. lineolatus and P. condanarus) with uncorrelated p-distances ranging from 11.9 ± 0.9% to 15.8 ± 1.6% for the ND4 gene and from 10.2 ± 0.8% to 13.8 ± 1.1% for the Cytb gene. Given the genetic differences along with morphological differences, we describe the specimen from the Turpan Basin as Psammophis turpanensis sp. nov. We provide detailed morphological descriptions, and compare this specimen with five Asian sand snakes and the Afro-Asian Sand Snake, P. schokari. In addition, we provide brief comments on the biogeography of Psammophis in China.

A new species of Andinobates (Dendrobatidae) is described from the East Andes of Colombia, just 37 km away from the Colombian capital, Bogotá. Andinobates supata sp. nov., represents the second known species of yellow Andinobates, and can be distinguished from the other, Andinobates tolimensis, by an unique combination of ventral and dorsal color patterns. Our phylogenetic analyses, based on ≈ 1120 bp from two mitochondrial markers (16S rRNA and cytochrome b) showed that this new taxon is sister to a clade formed by A. cassidyhornae, A. bombetes, A. opisthomelas, A. tolimensis and A. virolinensis. The new species appears to be restricted to a handful of small forest fragments (<10 ha) distributed in no more than 5 km2, between 1800–2000 m elevation, where the human activity is high. In addition, more than 90% of the original forest has been logged at the type locality, and its watersheds receive considerable agrochemical discharges. Altogether, the evidence suggests that this new species should be listed as Critically Endangered and should receive immediate attention regarding basic research and urgent conservation measures.

Habenaria luquanensis from Yunnan Province is described and illustrated. This new species most closely resembles H. delavayi in having a basal leaf rosette, flowers with a concave and abaxially keeled dorsal sepal and linear petals. It is distinguished by herbaceous, loosely arranged rosette leaves (versus tightly adpressed to each other), a lip which is 3-lobed only to 1/3–1/4 from the base and has narrowly oblong lateral lobes (versus deeply 3-lobed nearly to the base with linear-cuneate lateral lobes). Another similar species is H. finetiana, but this species can be distinguished by its cauline leaves, longer floral bracts, petals forming a hood with the dorsal sepal, a lip which is 3-lobed only in the upper half and  rhombic, serrate lateral lobes, a spur which is nearly as long as the ovary, and central rostellum lobe not clearly visible.

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.
