Frullania chilcootiensis Steph. and F. hattoriana J.D. Godfrey & G. Godfrey are two morphologically similar, little known species from northwestern North America. A Frullania specimen from Washington State, U.S.A. was recently discovered to have affinities with both species. The specimen’s shoots show variability in the length of the styli, as well as the number of cells composing them; two key morphological characters previously used to differentiate F. chilcootiensis from F. hattoriana. Based on this overlap and a detailed comparison of the branching and sexuality of the type specimens, F. chilcootiensis and F. hattoriana are here considered to be conspecific, with F. chilcootiensis having priority as the older name. The range of F. chilcootiensis is expanded into western Canada and the continental United States. A lectotype is designated for F. chilcootiensis from among the syntype specimens deposited in FH and G.

Aristolochia Linnaeus (1753: 960) (Aristolochiaceae) comprises about 500 species. The genus has worldwide distribution (Wanke et al. 2006). Recent findings of Aristolochia (Phuphathanaphong 2006, Xu et al. 2011, Huong et al. 2014, Do et al. 2015, Wu et al. 2015), together with the previous treatments for the Flora of Thailand (Phuphathanaphong 1987), the Flora of Vietnam (Pham 2000) and the Flora of China (Huang et al. 2003) confirmed the Thai & Indo-Chinese floristic region as a center of diversity for Aristolochia, with currently about 90 species. A high degree of endemism is found for specific countries (Huang et al. 2003, Phuphathanaphong 2006). However, the delimitation and taxonomic status of some species are still unclear due to limited access to specimen databases, especially for the type specimens in those countries. Notably, recent studies have significantly revised the taxonomic status of several previously described Aristolochia species when herbarium materials from multiple countries in the region were consulted (Do et al. 2014, Do 2016, Zu et al. 2016). On the basis of the examination of the protologue, the type specimens, and recent collections from the herbaria BKF, C, GXMI, HITBC, IBSC, KUN, PE and PEM, we conclude that Aristolochia longeracemosa B. Hansen & Leena Phuphathanaphong (1999: 557), described from collections made in northern Thailand, is conspecific with A. chlamydophylla C.Y. Wu ex S. M. Hwang (1981: 223) from southern China. Hence, we here propose the former as a new synonym of the latter. A detailed comparison of the morphological characters and habitat of these two species is provided.

Nearly a century ago, wing venation was introduced in gracillariid taxonomy as a means to diagnose closely related genera and species groups. Recent advances in non-destructive virtual micro-dissections suggest promising approaches with which to revisit the relevance of wing venation characters on historic primary type specimens. Many unique type specimens in Gracillariidae and other microlepidoptera groups preserved in museum collections are in poor condition, and over the course of history have suffered loss or damage to their abdomens. Consequently, genitalia morphology is not available for diagnoses and comparisons. In this paper we emphasize the need to include the type species and type specimens into the broader context of taxonomic studies on micro-moths in general and the family Gracillariidae in particular. The genus Caloptilia has a world-wide distribution and has been the subject of research for more than 200 years, yet the generic boundaries and groupings within the genus are still unresolved due to the lack of a reliable set of taxonomic characters obtained from the primary types. We describe a method of virtual descaling of the fore- and hindwings using the unset micro-moth type specimen of Caloptilia stigmatella Fabricius, 1781, in order to demonstrate that the study of historic and fragile type specimens and diagnoses of their internal morphological characters becomes possible by applying new and non-destructive technology.

Different Color

In 1958 Deichmann synonymized Holothuria inornata Semper, 1868 with Holothuria kefersteinii (Selenka, 1867). This nomenclature has been adopted until now. However, some specimens recently collected from the Mexican Pacific matched the original description of H. inornata Semper (1868) whereas others matched the original description by Selenka (1867). A morphological, molecular and ecological study of the specimens was conducted to confirm the identification of these specimens. The morphological characters of our specimens were compared with those contained in the original descriptions and figures of the types of both species. Besides the different color pattern of live specimens of both species, the main differences found are the presence of straight distally perforated rods in the dorsal papillae, and the presence of Holothuriophilus trapeziformis Nauck, 1880 in the cloaca of H. inornata, versus the absence of these kind of rods in the dorsal papillae, and the absence of symbionts in the cloaca in H. kefersteinii. The species identified by Deichmann (1958) as H. kefersteinii is, in fact H. inornata. Both species might have been confused because the morphology of preserved specimens is very similar and the presence of the straight rods in papillae might have been overlooked during identification. A more thorough review of the ossicles from the specimens, together with the comparison of ossicles from the type specimens, has allowed the resurrection of long-forgotten species, H. inornata

Based on critical observations on herbarium specimens (including type material) and living plants in the wild from its type locality, we demonstrate that Thalictrum kangdingense, recently described from Kangding county in western Sichuan province, China, is readily distinguishable from T. xinningense by an array of morphological characters but is actually conspecific with T. megalostigma, a species with its type locality also in Kangding. We therefore reduce T. kangdingense to the synonymy of T. megalostigma herein. The morphological distinction between T. baicalense and T. megalostigma is also clarified.

In the protologue, the author compared this species to L. souliei (Franchet) Sealy (1950: 296) and indicated that the former had basally saccate tepals compared to the latter, and based on this point the new species was recognized. However, the original description and type specimens of L. souliei has already displayed this feature (Fig. 3J–M in Sealy 1950; our Fig. 1A), until now, this feature has not been listed in both the Flora of Reipublicae Popularis Sinicae (Liang 1980), and Flora of China (Liang & Tamura 2000).

Patterns And Processes

Mastigias, the ‘golden’ or ‘spotted’ jellyfish, is distributed throughout the Indo-Pacific. Specimens are identified routinely as Mastigias papua, although eight species were described historically, and molecular analyses evince at least three phylogenetic species. Understanding species diversity in Mastigias has become a priority because of its growing relevance in studies of boom-bust dynamics related to environmental change, cryptic species, local adaptation, parallel evolution, and peripatric speciation. However, species delimitation and identification are inhibited by a dearth of type specimens for most species, including M. papua. We address these issues by resampling Mastigias from the type locality in Waigeo, West Papua, as well as in the Philippines, and by comparing cytochrome c oxidase subunit I and up to 34 morphological characters of 268 Mastigias specimens from surrounding regions in the Indo-Pacific. We also gathered data from the historical descriptions of the eight species of Mastigias to estimate the identity of the two other currently revealed clades. Using this integrative taxonomic approach, we re-describe Mastigias papua as endemic to the tropical western Pacific islands (including Papua, Palau, Enewetak) and designate a neotype for the species. Additionally, based on morphological similarity and geographic overlap, we identified a second clade most probably as M. albipunctatus (from Japan, Komodo, Berau and Philippines) and a third clade tentatively as either M. andersoni or M. ocellatus. This study highlights the benefits of combining molecular analyses, samples from type locations, traditional descriptions and statistical analyses of morphological variation in systematic studies, and the concomitant potential of such studies to increase understanding of evolutionary patterns and processes in Scyphozoa.

Morphological Differences

The subgenus Brygoomantis in the Madagascar-endemic genus Mantidactylus contains 12 nominal species but is in urgent need of taxonomic revision as many additional, genetically divergent but undescribed candidate species have been identified. We here take a first step towards a better resolution of this group by describing a new species, Mantidactylus schulzi sp. nov., occurring at the Tsaratanana and Manongarivo Massifs, differentiated in genetic, bioacoustic and sometimes morphological characters from its closest relatives. We show that upon detailed study, most species in Brygoomantis can be delimited by concordant differentiation of mitochondrial and nuclear DNA, and by bioacoustic and morphological differences. We flag this group of morphologically similar frogs as a test case where molecular data on historical type specimens by ancient DNA methods might be needed to reach a satisfying clarification of taxonomy and nomenclature. However, the status of the new species M. schulzi is not in doubt as it is morphologically distinct from most historical type specimens, and microendemic to a region in northern Madagascar from where no earlier names exist.

In recent decades, major advances in the systematics of the Western Hemisphere genus Paracloeodes Day have been made in South America. Despite the taxonomic progress, uncertainties in identification remain due to the morphological similarities among some nymphs and due to the general lack of knowledge of the imago stages (only 4 of 20 are described from throughout the range of the genus). This study addresses these impediments in part through description of the male imagoes of six species (P. atroari Nieto & Salles, P. binodulus Lugo-Ortiz & McCafferty, P. ibicui Lugo-Ortiz & McCafferty, P. pacawara Nieto & Salles, P. peri Nieto & Salles, P. waimiri Nieto & Salles), description of two new species based on morphologically distinct nymphs (P. aristotelesi sp. n. and P. carolinae sp. n.), description of one new species based on morphologically distinct nymph and male imago (P. prismatobranchus sp. n.); redescription of three species based on type material (P. ibicui Lugo-Ortiz & McCafferty, P. leptobranchus Lugo-Ortiz & McCafferty and P. eurybranchus Lugo-Ortiz & McCafferty); proposal of one new synonym based on morphological analyses of specimens from Bolivia, Brazil and Uruguay, including type specimens (P. pacawara = P. morellii Emmerich & Nieto); and the presentation of a new key to identify nymphs from South America to the species level.
