Rediscovery, resurrection and lectotypification of endemic Isoetes sampathkumarnii L. N. Rao from India

An interesting species of Isoetes was collected from Jambughoda, Wildlife Sanctuary, Gujarat. After a review of literature and comparison of the morphological characters with type specimens, it was identified as I. sampathkumarnii L. N. Rao. It is endemic species of south India and rediscovered after a lapse of 63 years. The species shows several features that make it unique in the genus. Earlier, I. sampathkumarnii was also treated as synonym of I. coromandelina L.f. and I. sahyadrii Mahabala. However, it has an idiosyncratic velum character and spore ornamentation that makes it different from other species. Hence, the authors resurrected it as a distinct species. The original material is ambiguous hence, a lectotype of I. sampathkumarnii has been designated here.

Based on literature survey, examination of type specimens and fieldwork, seven names of Carex are synonymized in the present paper: viz. Carex hypoblephara reduced to a synonym of C. glossostigma; C. dayunshanensis and C. wuyishanensis to synonyms of C. graciliflora; C. dolichogyne to a synonym of C. truncatigluma; C. kwangtoushanica to a synonym of C. tatsiensis; and C. martini to a synonym of C. rhynchophora. The holotype of Carex fokienensis is identified and confirmed at P. The putative endemic species Carex macrosandra (basionym: C. lanceolata var. macrosandra) is synonymized to C. lanceolata, whereas C. cavaleriensis, considered a synonym of the former, is here recognized as a distinct species. A lectotype is designated for C. lanceolata var. macrosandra.

The taxonomy of Eurasian angular or thin-toed geckos has undergone a great deal of revision over the last 30 years. However, it is clear that a desirable level of taxonomic resolution has not yet been attained as their taxonomic assignments are somewhat arbitrary. In this paper, we discuss two lesser-known gecko species, Cyrtopodion baturense (Khan and Baig 1992) and C. walli (Ingoldby 1922). One adult specimen of Cyrtopodion baturense (the only known specimen other than the type series) and a series of 53 C. walli collected by Walter Auffenberg and the Zoological Survey Department of Pakistan (ZSD) and subsequently deposited in the University of Florida Herpetology collection were compared to the type specimens. Specimens were examined for 46 morphological characters and measurements. Cyrtopodion baturense and C. walli are diagnosable and confirmed to be distinct species. Cyrtopodion baturense is known only from the holotype locality of Pasu and the nearby village of Dih, Hunza District, in the Gilgit Agency, Federally Administered Northern Areas (FANA), Pakistan, at 2,438–3,078 m elevations. Cyrtopodion walli is known from Ayun, Chitral, Bamburet Valley, Bermoghluscht, Drosh Tehsil, and 7.0 km N Drosh, in the Chitral District, Northwest Frontier, Pakistan, at 1,970–2,120 m elevations. We also conclude that the likely paratype (BMNH 1922.5.22.1) of Gymnodactylus walli is not conspecific with the holotype (BMNH 1910.7.12.1) and is most morphologically similar to Cyrtopodion tibetanus (Boulenger 1905). We concur with Khan (1992), based on our own examination of the syntype of Gymnodactylus chitralensis Smith, 1935, that G. chitralensis is a junior synonym of Gymnodactylus walli Ingoldby, 1922. Furthermore, the tail associated with the holotype of G. walli does not belong to that individual.

Diagnostic Characters

The subgenus Bodilus Mulsant & Rey, 1870 of the genus Aphodius Helwig, 1798 sensu lato comprises 30 species in the Palearctic fauna (Frolov 2001, 2002, Dellacasa et al. 2016 [treated as genus Bodilus]). Frolov (2001) reviewed the species of this subgenus from Russia and adjacent countries and suggested that the monotypic subgenus Paramelinopterus Rakovič, 1984 shares the main diagnostic characters of Bodilus. Frolov (2001) was unable, however, to examine the type species of Paramelinopterus, A. longipennis Rakovič, 1984, at that time. Král (2016) suggested that A. (Bodilus) inylchekensis Frolov, 2001 is a junior synonym of A. longipennis. Recently we have re-examined all the types as well as the additional material accumulated in the museums and can confirm that A. inylchekensis is a distinct species, but A. insperatus Petrovitz, 1967 and A. longipennis cannot be reliably separated by the morphological characters. In the present contribution we illustrate the major diagnostic characters of the species based on the type specimens and also provide a distribution map of the known localities of the species.

Floating Leaves

The recent studies on Sri Lankan Aponogeton underline the necessity of a taxonomic revision for the genus; especially with the recent discovery of two new endemic taxa and their described morphological affinities, revealing some misconceptions in the key morphological features used in identification and the overlapping morphology of the species within the genus. Accordingly, a morphometric analysis was carried out with 78 field collected specimens representing all six Sri Lankan Aponogeton species. The results indicate that A. kannangarae, a recently described endemic species which has been stated as closely resembling A. rigidifolius, is more similar to A. jacobsenii, with shared morphological characters, raising doubts if it is a distinct species. Further, the endemic A. jacobsenii, previously described and illustrated as a species with rarely occurring floating leaves, has been now described as with no floating leaves. Based on the results, a taxonomic update is presented with a key, full synonymy, descriptions and photographs.

Genealogical Concordance

Strobilomyces is broadly distributed geographically and serves an important ecological function. However, it has been difficult to delimit species within the genus, primarily due to developmental variations and phenotypic plasticity. To elucidate phylogenetic relationships among species within the genus and to understand its species diversity, especially in Asia, materials of the genus collected from five continents (Africa, Asia, Australia, Europe, and North/Central America) were investigated. The phylogeny of Strobilomyces was reconstructed based on nucleotide sequences of four genes coding for: the largest and the second largest subunits of the RNA polymerase II (RPB1 and RPB2); the translation elongation factor subunit 1-α (TEF1); and the mitochondrial cytochrome oxidase subunit 3 (COX3). The combined results based on molecular phylogenetics, morphological characters, host tree associations, and geographical distribution patterns support a new classification consisting of two sections, sect. Strobilomyces and sect. Echinati. Using the genealogical concordance phylogenetic species recognition (GCPSR) approach, at least 33 phylogenetic species in Asia can be delimited, all of which are supported by morphological features, and five phylogenetic species remain to be described. The mountainous region of Southwest China is especially special, containing at least 21 species and likely represents a centre of diversification. We further compared our specimens with the type specimens of 25 species of Strobilomyces. Our comparisons suggest that, there are a total of 31 distinct species, while S. sanmingensis, S. verruculosus, S. subnigricans, and S. zangii/S. areolatus, are synonyms of S. mirandus, S. giganteus, S. alpinus and S. seminudus, respectively. Eight new species, namely, S. albidus, S. anthracinus, S. calidus, S. cingulatus, S. densisquamosus, S. douformis, S. microreticulatus and S. pinophilus, are described. A dichotomous key to the Asian Strobilomyces species is provided.

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao & Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu & Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu & Li, 2006 (Fam. Linyphiidae) are also illustrated.

Non Destructive

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

Biological Differences

While investigating the biology of the North American species of Hypomolyx, field workers in Manitoba found a vestigial, or short-winged, and a long-winged form under apparently identical conditions in about equal numbers. Although biological differences were nor then apparent, there was doubt as to whether they were dealing with one dimorphic species or with two distinct species, A search for morphological characters brought to light numerous differences between the two forms, supporting the view that two species were present. These differences, a description the previously unrecognized species, and notes concerning the status of the genera Hylobius and Hypomolyx are reported below.

Cabomba schwartzii was described by Rataj in 1977. The species discovered in the Brazilian Amazon was said to differ from other Cabomba species in having two sepals, two petals and a lobate petal base. According to the 1991 study of Ørgaard, C. schwartzii is similar to C. aquatica in other morphological characters (C. aquatica has flowers with three sepals and three petals) and since variation in number of floral parts is common in the genus, Ørgaard synonymized both species. After an analysis of C. schwartzii type material, other herbarium collections and location of four populations (two with C. schwartzii characteristics and two with C. aquatica characteristics), we conducted an integrated morphological and genetic study to evaluate whether or not C. schwartzii is a distinct species from C. aquatica. The results reveal the species to be distinct from each other and therefore C. schwartzii should be reestablished. The floral formula for C. schwartzii is K2 C2 A2+2 G1, versus K3 C3 A3+3 G2 for C. aquatica. A detailed species description and the geographical distribution of C. schwartzii are presented with a dichotomous key to distinguish both species, together with illustrations.
