A New Species

The genus Manfreda (Asparagaceae) contains 35 species. A species complex includes plants similar to M. gutttata, which are characterized by the protrusion of the ovary into the perigone tube. This feature was found in specimens recently collected in western Mexico. After a morphological analysis, we found that some of the plants differ from the other species in this complex. Hence, we describe a new species named M. occidentalis morphologically similar to M. planifolia but can be distinguished from it by the oblong-ovoid corm, channeled leaves, which are papillate on both sides, perigone 1.8–2.5 cm long, funnel-shaped, yellowish and light purple striate, perigone tube 0.3–0.7 × 0.2–0.4 cm, filaments adnate to the perigone and arising 0.3–0.7 cm above the ovary apex, anthers 0.9–1.1 cm long, and style 2.1–3.5 cm long, exceeding the perigone tube by 1.8–3 cm at anthesis. Manfreda occidentalis also resembles M. chamelensis; however, phenologic asynchrony is a notable difference between them as well as the shape of the leaves and the length and shape of perigone tube and lobes. A distribution map, photographs, and a key to identify species of Manfreda which grow in western Mexico accompany the description.

Ferula melitensis, a new species from the Malta Archipelago, is described and illustrated. It belongs to the taxonomic group of F. communis, showing close relationships mainly with F. tunetana, F. arrigonii, F. communis s.str. and F. glauca, from which it differs in several features regarding the stem, leaves (mainly for shape and size of terminal segments), flowers and mericarps; other significant differences regard the ecology and phenology. The investigations, carried out on living plants, herbarium material and literature data, regard the morphological analysis of vegetative and reproductive structures, the anatomy of terminal leaf segments and mericarps, as well as the shape and size of seedlings. Previous phylogenetic approaches, based on nuclear and plastidial genome, have allowed to clarify better the relationships among F. melitensis and the other species of this group.

Pyura stolonifera is a large solitary ascidian found in Africa, Australasia and South America. The taxonomic status of different populations of this species is disputed, especially since there is evidence for several distinct morphological and genetic units that point towards the existence of multiple cryptic species. While some researchers still recognize P. stolonifera as a single species, others treat the different populations as distinct species. Here, we present a revision of the P. stolonifera species complex based on the examination of samples from all regions where there are reliable reports of this taxon. We recognize four species that are both morphologically and genetically distinct, one of which is new to science and is formally described here. This species is morphologically distinct from the other three members of the species complex in terms of the colour and texture of the tunic, the arrangement of the gonads within the gut and the shape of the dorsal tubercle, among other characters. We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

A New Species

A new endemic species, Verbascum shahsavarensis, is described from north of Iran. Based on two unique characters of this species, these being two anterior longitudinally obliquely inserted anthers and an ebracteolate pedicel, we compared it to species described by Murbeck in 1933. The new species can be easily distinguished from the other Iranian species by having bi-colored hairs on the stamen filaments and the unique anther and pedicel characters. A distribution map is provided. The name of new species comes from Shahsavar, the ancient name of Tonekabon, an old coastal city on the Caspian Sea.

A New Species

During a soil zoological expedition to São Tomé and Príncipe in 2010 by the California Academy of Sciences, millipedes of the genus Globanus were collected. Samples of G. marginescaber (Karsch, 1884) and G. integer (Karsch, 1884) were recovered in addition to those containing a new species. Globanus drewesisp. nov. is described and additional records, illustrations, and descriptive notes are given for the other two species. A key to all three species of the genus is provided, and a distribution map is presented. The monotypic genus Lobogonus Demange, 1971, which includes L. trilobatus Demange, 1971, from Sierra Leone, mainland western Africa, is revalidated and removed from synonymy under Globanus. Lobogonus is illustrated from a type specimen.

A New Species

We describe a new frog species of the Spinomantis bertini species complex based on congruent genetic evidence from mitochondrial and nuclear DNA sequences as well as minor morphological differences. A molecular phylogeny derived from the mitochondrial 16S rRNA gene revealed that Spinomantis mirus sp. nov. is sister to a clade containing the other two described species of the species complex, S. bertini and S. beckei, but strongly differentiated from these two species by 8.1–9.8% pairwise distances in this gene. DNA sequences from two nuclear genes revealed that S. mirus sp. nov. shares no alleles with these two species. Phenotypically, S. mirus sp. nov. differs from the other species of the complex by its larger size and some aspects of its coloration, including clear mottling on the flanks, tri-color banding on the legs, and distinct brown dots on the dorsum. The new species is so far only known from Pic d’Ivohibe Special Reserve. Its distribution thus appears to not overlap with those of the other two species, which as far as known are restricted to the Andohahela Massif in the extreme South-East of Madagascar, at a distance of about 250 km from Ivohibe.

A New Species

Only a few previous surveys of the deep-water planktonic fauna have been accomplished off western Mexico, in particular in the Gulf of California. Samples of pelagic amphipods were obtained between surface and as deep as 2394 m using different gear during an extensive survey in this area. Among these samples, nine species of the genus Scina were recognized, including 78 specimens: 27 males and 51 females. The genus Scina inhabits mesopelagic waters at depths over 200 m, a community that remains largely unknown. The material examined includes a new species, the first reported from the Gulf of California, which is described and compared with its closest congeners, S. setigera Wagler, 1926 and S. parasetigera Zeidler, 1990. These three species share the presence of a long bristle on the base of the dactylus of pereopods 5 and 6. Scina sp. nov. differs from these other two species mainly by: 1) the shape and proportions of pereiopods 1–7; 2) the presence of three inner spiniform elements on uropod 1; 3) the insertion of the exopod on distal 1/3 of uropods. Of the remaining species collected during the survey S. borealis was by far the most abundant and widely distributed, followed by S. wolterecki and S. marginata. The other five species, S. curvidactyla, S. nana, S. pacifica, S. setigera, and S. submarginata, were represented by one or two specimens only. Co-occurence of species of Scina in samples was low with a maximum of four species in a single sample, all associated with S. borealis, the most common species. The distribution of Scina species collected during this survey is briefly discussed.

Cladocolea spathiflora, a new species from Guerrero, Mexico, is described and illustrated. The new taxon is compared with C. pringlei and C. grahamii, species with similar characteristics; however, the flowers of C. spathiflora are associated to a spathaceous receptacle, while in the other two species the flowers are sessile on the axis of the inflorescence. An identification key and a distribution map of these taxa are included.

Vicia mingyueshanensis, a new species from the Mingyue Mountain Region of western Jiangxi, China, is described and illustrated. It is a perennial climbing liana that always links to riparian woods. A morphological comparison indicated that the new species is closely similar to Vicia taipaica K. T. Fu and Vicia dichroantha Diels; however, it differs from the other two species by several salient characters, such as plant indumentum, stipule shape, corolla colour, bractlet shape and calyx shape. Photographs, a preliminary conservation assessment, table of morphological characters and distribution map comparing this new species to two morphologically-similar species are also provided.
