This study contributes to the morphological characterization of Ombrophytum villamariensis, a new species of Neotropical Balanophoraceae recently described for Colombia. The study revealed the presence of diagnostic characters in the pollen grain such as small size and a circular endoaperture. Unlike other species, only tricolporate pollen grains were observed.

Epimedium muhuangense (Berberidaceae), a new species from Guizhou, China, is described and illustrated. This species is most closely similar to E. elachyphyllum in having simple leaves, petals shorter than inner sepals, flowers less than 10 mm in diameter and in having the same pollen morphology as well, but differs by having stout, short rhizomes, two opposite, glabrous leaves on flowering stems, and paniculate inflorescences. The chromosomes of E. muhuangense is counted as 2n = 12 and the karyotype is formulated as s 2n = 2x = 6m (2sat) + 6sm. Line illustrations, color photographs, and micrographs of chromosomes and of pollen grains of E. muhuangense are provided.

A new species of gymnostome, Urotricha vitrea n. sp., is proposed. The morphological characterization of this new freshwater ciliate is as follows: 46–27 μm × 43–26 μm in size; a spherical macronucleus; 20–23 somatic kineties; a caudal cilium; brosse with 4, 3, 2 rows of pairs of kinetosomes; and circumoral infraciliature with 13–16 pairs of kinetosomes. In addition, the conjugation process of this species is reported. It includes three maturation divisions and three synkaryon divisions.

A New Species

The genus Colaconema, containing endophytic algae associated with economically important macroalgae, is common around the world, but has rarely been reported in Taiwan. A new species, C. formosanum, was found attached to an economically important local macroalga, Sarcodia suae, in southern Taiwan. The new species was confirmed based on morphological observations and molecular analysis. Both the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) and cytochrome c oxidase subunit I (COI-5P) genes showed high genetic variation between our sample and related species. Anatomical observations indicated that the new species presents asexual reproduction by monospores, cylindrical cells, irregularly branched filaments, a single pyrenoid, and single parietal plastids. Our research supports the taxonomic placement of C. formosanum within the genus Colaconema. This study presents the third record of the Colaconema genus in Taiwan.

AbstractA new species belonging to the genus Belondira is described from natural areas in Iran. Belondira coomansi n. sp. is characterized by its general size, the dimensions and appearance of its lip region, presence of distinct labial and post-labial sclerotization, the length of the odontostyle and its inconspicuous lumen and aperture, the length of the neck and its pharyngeal expansion, the reduction of the female anterior genital branch to a simple uterine sac, a very short posterior uterus, the anterior position of the vulva, the length and shape of the caudal region with distinctly thick cuticle at its tip, the length of the spicules, and the presence of only one pair of ventromedian supplements. The new species is close to Belondira brevibulba, B. sacchari, B. tenuidens and B. thornei, and it is compared to them. Molecular characterization (D2–D3 expansion segments of the rRNA large subunit) of the new species is also provided, representing only the second species of this genus for which any DNA sequence data are available.

Female Genital

We discovered the immature stages of Wyeomyia shannoni Lane & Cerqueira, 1942, unknown for almost 80 years, and found that they, as well as the adult male, are identical with those previously described for Sabethes (Peytonulus) paradoxus Harbach, 2002. Consequently, the species described by Lane and Cerqueira is here considered a senior synonym of Sa. paradoxus and is transferred to the genus Sabethes, hereafter named Sabethes (Peytonulus) shannoni (Lane & Cerqueira, 1942), comb. n. As the name shannoni is preoccupied in the genus Sabethes, the species known as Sabethes (Sabethes) shannoni Cerqueira, 1961 is here renamed Sabethes (Sabethes) cerqueirai Nascimento-Pereira, Neves, Lourenço-de-Oliveira & Motta, nom. n. We improved the morphological characterization of Sa. (Pey.) shannoni (Lane & Cerqueira) by including an illustration of the female genitalia, larval mouthparts and the female genital lobe of the pupa. Finally, we describe and illustrate a new species of Sabethes closely related to Sa. (Pey.) shannoni, named Sabethes (Peytonulus) harbachi Nascimento-Pereira, Guimarães, Lourenço-de-Oliveira & Motta, sp. n.

The taxonomic history, general description and distribution are provided for Myoxanthus. Morphological characterization of the vegetative and reproductive organs is illustrated with photographs. A list of the 52 accepted species includes synonyms and distribution; most are illustrated with a flower photograph. Lectotypes for M. frutex, M. lonchophyllus, M. neillii, M. pulvinatus, M. punctatus, and M. serripetalus are designated, and a neotype is selected for M. melittanthus. Myoxanthus parvilabius is reported for the first time for Colombia. The circumscription of M. lonchophyllus is reevaluated, Pleurothallis pennellia is recognized as a distinct taxon and transferred to Myoxanthus, and Myoxanthus panamense, a new species related to M. scandens, is described from Pamana.

Leptodermis hechiensis from Guangxi, China, is described as a new species. The species differs from similar L. yangshuoensis by triangular calyx lobe and 3-lobed style, and from L. coriaceifolia by subcoriaceous leaf blade and shorter bracteoles. Its leaf epidermis and pollen morphology were observed by SEM. Diagnostic characters and distribution maps of the above three species are provided too.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.
