Impatiens longiaristata (Balsaminaceae), a new species from western Sichuan Province in China, is described and illustrated here based on morphological and molecular data. It is similar to I. longiloba and I. siculifer, but differs in its lower sepal with a long arista at the apex of the mouth, spur curved downward or circinate, and lower petal that is oblong-elliptic and two times longer than the upper petal. Molecular analysis confirmed its placement in sect. Racemosae. Simultaneously, during the inspection of the protologues and type specimens of allied species, it was found that the types of two names from this section were syntypes based on Article 9.6 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code). According to Articles 8.1, 9.3, and Recommendations 9A.1, 9A.2, and 9A.3, the lectotypes of these two names are here designated.

A new species of Sciaphila (Triuridaceae), S. kozushimensis Suetsugu, is described from Kozu Island, Izu Islands, Japan. The new species is similar to S. tosaensis in having unisexual flowers (the female towards the base of the rachis), perianth-segments without any appendages and club-shaped style that is as long as or slightly exceeds ovary in the flowering stage. However, it is distinguishable by smaller male flowers, wide and acuminate male perianth segments and somewhat dissimilar perianth segments. An illustration and molecular analysis based on ITS sequences of the new species are provided. A key to the Japanese Sciaphila is also provided for identification of these rare mycoheterotrophic plants.

Carex Linnaeus (1753: 972) is one of the largest genera of angiosperms with more than 2000 species in the world (Reznicek 1990, Goetghebeur 1998). In India, Karthikeyan et al. (1989) and Prasad & Singh (2002) reported 160 species, 1 subspecies and 29 varieties. Recently, Viji et al. (2016) recorded a new species from Tamil Nadu which is new to the Indian flora, namely Carex nilagirica Viji, Pandur., Deepu & G.C. Tucker (2016: 1). However, there is another Carex nilagirica published by Hochst ex Steudel (1855: 207), which is currently treated as a heterotypic synonym of Carex filicina Nees (1834: 123). As a result, and under the International Code of Nomenclature for algae, fungi and plants (McNeill et al. 2012), the name Carex nilagirica Viji, Pandur., Deepu & G.C. Tucker is illegitimate, as it is a later homonym of Carex nilagirica Hochst ex. Steud. (Art. 53.1). Therefore, a new name Carex panduranganii is proposed as a replacement name for Carex nilagirica Viji, Pandur., Deepu & G.C. Tucker.

Aster oliganthus (Asteraceae, Astereae), a new species from two populations of the eastern Mt. Hengduanshan region in western Sichuan, China, is illustrated and described. The new species is similar to A. ageratoides in habit, triplinerved leaves, lower and basal leaves withering at anthesis, terminal paniculate-corymbiform to corymbiform synflorescences, and 3–5-seriate phyllaries, but differs from it by falcate leaves with long acuminate to caudate apex, 5–7(–9) ray florets, and (2–)4–5 disc florets. Based on the phylogenetic analysis of internal and external transcribed spacers of nrDNA, we demonstrated that the two populations form a highly supported clade, are closely related to but not nested within the A. ageratoides clade, which supports that A. oliganthus is a good species and belongs to A. subgen. Aster sect. Ageratoides. Cytological observation shows that the new species is diploid with its karyotype being 2n =2x =18 = 16m + 2sm.

Kodaianellissus gibbusis sp. nov. is described from Rawlakot, Azad Jammu & Kashmir (Pakistan), which is first record of the genus Kodaianellissus Wang, Bourgoin & Zhang, 2017 from the country. Morphological characters including male genitalia structure are described and illustrated. A checklist and key to all species of Kodaianellissus are provided. A molecular analysis with morphological characters indicates its placement into the Kodaianellissus.

Abstract—Psidium involutisepalum, a new species of Myrtaceae, is described and illustrated. The species is easily recognized by the combination of floral buds with calyx minute, truncate or rounded, 0.2‐0.5 × 0.5‐1 mm, involute in fruit, facing the receptacle. The fruits are rounded to pyriform, 20‐30 × 13‐20 mm, yellow when mature, glabrous, striate, sepals involute, facing the receptacle, seeds 1‐6, 7‐9 × 6‐7 mm, rounded to angular. Based on the types and specimens examined, literature survey and the rules of international code of nomenclature, Psidium turbinatum is recognized here as a legitimate name. The relationship of Psidium involutisepalum, P. myrtoides, and P. turbinatum is discussed and comments concerning their taxonomy and ecology are also provided.

Pedicularis inconspicua Vved (18 June, 1955: 811) was originally described as a new species from Uzbekistan and six years later considered as endemic for this country (1961:492). As part of the ongoing work for the preparation the checklist of vascular plant of Central Asia, we realized that the name P. inconspicua is an illegitimate later homonym of P. inconspicua Tsoong (18 January, 1955: 292), according to the Art. 53.1 of the International Code of Nomenclature for algae, fungi, and plants (ICN) (Turland et al. 2018).

In our recently published monograph of the Octopleura clade of Miconia Ruiz & Pavón (1794: 60, Gamba & Almeda 2014) we proposed a number of new combinations and new names to reflect the nested position of this assemblage of 33 species within the large and diverse Neotropical genus Miconia based on morphological and molecular data sets. In proposing the new name, Miconia magnifolia Gamba & Almeda (2014: 91), we overlooked the epithet of a heterotypic synonym that should have been adopted. Miconia magnifolia is therefore illegitimate and nomenclaturally superfluous according to Article 52.1 of the International Code of Nomenclature (McNeill et al. 2012) and is to be rejected because it included the type of a heterotypic synonym whose epithet was available and not already pre-empted in Miconia.

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.
