Tentative Identification

The genus Pseudophysaloptera, recognized as a genus distinct from Physatoptera, is tentatively considered monotypic. The several species previously assigned to the genus Pseudophysaloptera, and the closely related species Physaloptera kotlani, have been reduced to one polytypic species, Pseudophysaloptera formosana, with two subspecies, P. f. formosana and P. f. soricina. The former occurs in Oriental species of Suncus, while the latter occurs in Palaearctic and Ethiopian soricid insectivores. North American specimens, which may represent a distinct species, are tentatively assigned to P. f. soricina. Presently available collections are only sufficient for a tentative identification of the Nearctic form.

During a taxonomic revision of Selaginella from the Himalaya which is a part of the ongoing “Flora of Pan-Himalaya” project, we studied the taxonomy of Selaginella monospora and its closely related species. We found that S. microclada once treated as a synonym of S. monospora should be accepted as a distinct species. In contrast, S. trichophylla, S. monospora var. ciliolata, S. medogensis, and S. effusa var. dulongjiangensis are reduced to synonymy of S. monospora based on molecular phylogenetic analyses and morphological characters. Selaginella monospora is characterized by denticulate to ciliolate leaves and strongly dimorphic sporophylls vs. denticulate leaves and slightly dimorphic sporophylls in S. microclada. A lectotypification of S. medogensis was also made in the present study.

Recent Evaluation

The cycad genus Dioon comprises 17 species from Mexico and Honduras, all of them delimited based on their morphological variation and geographic distribution. A recent evaluation of the biological variation among Dioon populations from Oaxaca and Chiapas, Mexico, demonstrated that the concept of the species Dioon merolae actually consists of three lineages that should be recognized as different taxa. One lineage was already described as Dioon oaxacensis, leaving the concept of Dioon merolae comprising two lineages distributed on both sides of the Isthmus of Tehuantepec. However, there are conspicuous morphological differences between these two lineages. Here, we tested whether such a differentiation within the concept of Dioon merolae merits the differentiation of two different taxa. We evaluated the qualitative and morphometric variation among populations belonging to the Dioon merolae lineages, and compared it with the closely related species Dioon oaxacensis. Morphological observations and statistical tests demonstrated that the populations of southeastern Oaxaca, traditionally considered as part of Dioon merolae, represent a distinct species that we described as Dioon salas-moralesae. Identifying the diagnostic characters of this new species helps enable an understanding of the criteria that should be considered to delineate the boundaries between other cycad species.

Despite their importance as potential biological control agents, species of the campoplegine genus Campoplex Gravenhorst, 1829 are hard to identify. Previous works provided short descriptions or poor illustrations of crucial characters, meaning it is often impossible to distinguish closely related species. We provide illustrations to identify species of the Campoplex difformis group and redescriptions of and illustrations for C. difformis (Gmelin, 1790), C. capitator Aubert, 1960, C. dubitator Horstmann, 1985, C. formosanae Horstmann, 2012, and C. unicingulatus (Schmiedeknecht, 1909). In addition, the taxonomic status of C. difformis is clarified; a lectotype is designated for C. capitator in Aubert’s collection in Lausanne and the host record for this species on Ancylis mitterbacheriana (Denis & Schiffermüller, 1775) is queried; Campoplex corsicator Aubert, 1960 stat. nov. is removed from synonymy with Campoplex tibialis (Szépligeti, 1916) and redescribed.

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

Leaf Symptoms

Two Alternaria species, A. carotiincultae and A. glehniae sp. nov. are isolated from necrotic leaf symptoms of Ligusticum chuanxiong Hort. and Glehnia littoralis Fr. Schmidt ex Miq in China, respectively. The two species are determined as distinct species belonging to sect. Radicina of Alternaria based on morphology and a multigene analysis of ITS, EF-1α, RPB2 and ATPase sequences. Alternaria glehniae is illustrated here as a novel species because the conidial size, septa and sporulation patterns are different from its closely related species. A. carotiincultae is also described as a new record in China.

Shed Light

The Brazilian porcupine was one of several species described and illustrated by the 17 th -century naturalist Georg Marcgrave, whose text was among the primary references upon which Linnaeus based his Hystrix prehensilis. As currently understood, Coendou prehensilis is a wide-ranging polytypic taxon that has never been revised and may represent a complex of closely related species. Given that no name-bearing type specimen of C. prehensilis is believed to be extant, and in order to avoid ambiguous application of this name, we designate a specimen collected at the type locality in Pernambuco, northeastern Brazil, as the neotype for Hystrix prehensilis Linnaeus. The geographic distribution of mitochondrial DNA haplotypes suggests that specimens from west-central Brazil previously identified as “Coendou prehensilis” belong to a different species, but only a comprehensive taxonomic revision of the genus will shed light on species limits and the geographic ranges of C. prehensilis and other congeneric forms.

Taxonomic History

The plant that was first called “Odontoglossum wyattianum” by Gurney Wilson was exhibited at a meeting of the Royal Horticultural Society on January 3, 1928. No official description was ever published and no type specimen was ever designated, or has surfaced, hence making this distinct species a taxonomic ‘ghost’. The taxonomic validation of Odontoglossum wyattianum is made here through the designation of a holotype, together with a diagnosis, a brief taxonomic history and comparison with similar and closely related species.

Two New Species

Two new species of Euphorbiaceae (sensu stricto), Mallotus bicarpellatus (Acalyphoideae) and Croton nepalensis (Crotonoideae), are described from Nepal. Mallotus bicarpellatus is closely related to M. philippensis but differs in having 1 or 2 pairs of leaf glands distinctly separated from the petiole attachment, pistillate flowers with staminodes and longer pedicels, and fewer locules and stigmas. Croton nepalensis differs from C. tiglium in having leaves with truncate, subcordate or rounded base, smaller, broadly ovoid capsules, and smaller seeds. A table is provided showing how Croton nepalensis differs from other closely related species. Croton himalaicus is here regarded as a synonym of C. tiglium, though it has been treated variously as a distinct species or a synonym of C. tiglium or C. birmanicus by recent authors. Distribution maps and graphs of altitudinal distribution are given for the new species.
