Molecular Studies

Recent molecular studies have suggested that the clicking beetle families Elateridae, Eucnemidae, Throscidae, and Cerophytidae evolved in the Jurassic and diversified in the Cretaceous. These studies paid little attention to fossils, using them only as dating tools. The identification of Elateridae fossils is challenging, as external synapomorphies are not known for this family. Elateridae can be identified only as something not belonging to the other related families, all of which have diagnostic synapomorphies. Most subfamilies and tribes of Elateridae do possess definite diagnostic characters, however, making their identification feasible. We checked the 28 Elateridae described from Chinese Mesozoic deposits. Twelve were Elateridae, seven were Eucnemidae, and one was a Throscidae. Three species could be Eucnemidae, but showed aberrant characters. Five species could not be placed and may not belong to Elateroidea at all. On the basis of these results we suggest that all previously described Elateridae fossils should be re-checked. They should be searched for synapomorphies defining Eucnemidae, Throscidae, and Cerophytidae. If such characters are not present, a click beetle type of fossil can be placed in Elateroidae incertae sedis. The Mesozoic Chinese Elateridae fossils all belong to clades that do not exist today, whereas the Mesozoic Eucnemidae subfamilies are extant ones. This may be the source of the disagreement between Elateridae fossil age and datings based on molecular studies. One new combination was made: Desmatus ponomarenkoi (Chang, Kiretjshuk & Ren, 2009) NEW COMBINATION (= Paradesmatus ponomarenkoi Chang, Kirejtshuk & Ren, 2009).

The Indian fauna of the genus Microplitis Foerster, 1862 is revised. An illustrated key to eight species including the description of one new species, M. murkyi sp. nov., is provided. Six previously described species, namely: M. ajmerensis Rao & Kurian, M. demolitor Wilkinson, M. indicus Marsh, M. manilae Ashmead, M. prodeniae Rao & Kurian, and M. spodopterae Rao & Kurian are elaborated with taxonomical variations and extended distribution. Two species, M. bageshri Sathe, Inamdar & Dawale and M. dipika (Bhatnagar) are considered incertae sedis. A new combination is suggested for Snellenius maculipennis (Szepligeti) which is placed into synonymy with Microplitis. Information on taxonomic history of the genus, diagnostic characters of all the included species, distribution and host relationships are provided.

Cichlids of the tribe Heroini have long been a source of taxonomical conflict. In particular, the species included in the Herichthys bartoni group have failed to be recovered as monophyletic in different molecular studies. In this paper we use traditional and geometric morphometrics to evaluate morphological variation in the species included in the H. bartoni complex in order to evaluate the number of species it contains. An update of a previously published DNA barcoding study suggests the existence of three genetic clusters that included the six recognized species analyzed in this study, none of them recovered as monophyletic. On the other hand, geometric morphometrics arise as a useful tool to discriminate species due that traditional morphometrics showed a high overlap in the characters analyzed that prevents the proposal of diagnostic characters.

First Time

Studies of the origin and diversification of major groups of plants and animals are contentious topics in current evolutionary biology. This includes the study of the timing and relationships of the two major clades of extant mammals – marsupials and placentals. Molecular studies concerned with marsupial and placental origin and diversification can be at odds with the fossil record. Such studies are, however, not a recent phenomenon. Over 150 years ago Charles Darwin weighed two alternative views on the origin of marsupials and placentals. Less than a year after the publication of On the origin of species, Darwin outlined these in a letter to Charles Lyell dated 23 September 1860. The letter concluded with two competing phylogenetic diagrams. One showed marsupials as ancestral to both living marsupials and placentals, whereas the other showed a non-marsupial, non-placental as being ancestral to both living marsupials and placentals. These two diagrams are published here for the first time. These are the only such competing phylogenetic diagrams that Darwin is known to have produced. In addition to examining the question of mammalian origins in this letter and in other manuscript notes discussed here, Darwin confronted the broader issue as to whether major groups of animals had a single origin (monophyly) or were the result of “continuous creation” as advocated for some groups by Richard Owen. Charles Lyell had held similar views to those of Owen, but it is clear from correspondence with Darwin that he was beginning to accept the idea of monophyly of major groups.

The genus Xylaplothrips is re-diagnosed, 11 species are listed as appropriately included in this genus of which three are new combinations from Haplothrips (X. acaciae; X. collyerae; X. gahniae). A further six species are listed as incertae sedis within Xylaplothrips and a key is provided to the four species of this genus known from Australia including X. anarsius sp.n. The genus Mesandrothrips is recalled from synonymy with Xylaplothrips, and a list is provided of 20 appropriately included species of which 14 are new combinations from Xylaplothrips (M. caliginosus; M. clavipes; M. darci; M. dubius; M. emineus; M. flavitibia; M. flavus; M. inquilinus; M. montanus; M. pictipes; M. pusillus; M. reedi; M. subterraneus; M. tener), and one is a new combination from Haplothrips (M. inquinatus). A key is provided to 10 species of this genus known from Australia, including three species transferred from Haplothrips, together with M. austrosteensia sp.n., M. googongi sp.n., M. kurandae sp.n., M. lamingtoni sp.n. and M. oleariae sp.n. The type species, M. inquilinus, is widespread across Southeast Asia as an invader of thrips galls, and Haplothrips darci Girault based on a single female from Queensland is considered closely related.

A New Species

A total of 14 species in seven tingid genera have been described from the mid-Cretaceous Burmese (Kachin) amber from northern Myanmar, with very distinct paleofauna. Here, a new species of a new genus, Burmavianaida anomalocapitata gen. et sp. nov., is described from Kachin amber. This new species can be readily distinguished from the other described tingid taxa by the apparently smaller body and the structures of the pronotum and hemelytron. Burmavianaida gen. nov. shares the diagnostic characters with two clades composed of three extant subfamilies (Cantacaderinae + Tinginae) and Vianaidinae and may represent an extinct clade distinct from them. To the best of our knowledge, B. anomalocapitata sp. nov. is the smallest species of Tingidae among over 2600 described species. Our new finding supports the hypothesis of the miniaturization phenomenon of insects in Kachin amber, as suggested by previous studies.

Block Pulse Functions

We introduce a new combination of Bernstein polynomials (BPs) and Block-Pulse functions (BPFs) on the interval [0, 1]. These functions are suitable for finding an approximate solution of the second kind integral equation. We call this method Hybrid Bernstein Block-Pulse Functions Method (HBBPFM). This method is very simple such that an integral equation is reduced to a system of linear equations. On the other hand, convergence analysis for this method is discussed. The method is computationally very simple and attractive so that numerical examples illustrate the efficiency and accuracy of this method.

Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries (i.e. documents certifying deposition and availability of type strains). It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below, and these authors' names will be included in the author index of the present issue and in the volume author index. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in bacteriological nomenclature. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.

The genus Macroderes Westwood, 1842 (Scarabaeidae: Scarabaeinae, tribe incertae sedis) is practically endemic to South Africa with only one species that is found little north in southern Namibia. The ranges of the species are limited to the winter-fall and bimodal biomes of South Africa comprising the regions of Richtersveld as extreme points of its northerly distribution, and extending to the south through Namaqualand to Cape Agulhas. The taxonomy of the genus is revised. Fourteen valid species are recognised and three others are of doubtful validity. Seven new species are described, these are: M. cederbergensis Abdalla & Deschodt, new species, M. tortuosus Abdalla & Scholtz, new species, M. gifboomi Abdalla & Scholtz, new species, M. leipoldti Abdalla & Deschodt, new species, M. oreatus Abdalla & Deschodt, new species, M. porselinus Abdalla, new species, and M. soleiana Abdalla & Deschodt, new species. Macroderes nitidus Harold, 1877 is redescribed and its lectotype is designated. The diagnostic characters as well as an updated geographic distribution of each species are summarised. An updated key of the genus, photographs of habitus, sclerites of internal sac, pronotum, pronotal punctures and elytra also are provided.
