The genus Pleioplectron was first described by Hutton (1896) and included six New Zealand species. This genus has since had three species moved, one each to the genera Pachyrhamma Brunner von Wattenwyl, 1888, Miotopus Hutton, 1898 and Novoplectron Richards, 1958. Here we clarify the status and appearance of Pleioplectron simplex Hutton, 1896 (incl. P. pectinatum Hutton, 1896 syn. nov.) and P. hudsoni Hutton, 1896, as well as P. thomsoni (Chopard, 1923) comb. nov., which is transferred from the genus Weta Chopard, 1923. The genus Weta is newly synonymised with Pleioplectron. We also describe seven new species of Pleioplectron from South Island, New Zealand: P. auratum sp. nov., P. caudatum sp. nov, P. crystallae sp. nov., P. flavicorne sp. nov., P. gubernator sp. nov., P. rodmorrisi sp. nov and P. triquetrum sp. nov. We base these descriptions on morphology using fresh specimens of both male and female adults, and provide support for each with DNA sequence variation (mtDNA, partial COI).
A total of nine families of Trichoptera were identified from material collected in Malaise and light traps in the western part of Nyungwe National Park, southwestern Rwanda, late October 2018. Included in the material was an undescribed species of Pisuliidae which is described herein as Silvatares laetae Ngirinshuti & Johanson sp. nov. The new species adds to the six Pisuliidae species previously recorded for the East African region, five endemic to Tanzania and one to Uganda. This study portrays the first results of an ongoing survey on the Trichoptera fauna of Rwanda.
We revise the genus Attemsostreptus Verhoeff, 1941 based on type material of the type species, A. costatus Verhoeff, 1941, synonymise A. orobius (Kraus 1958) with A. costatus and describe a second species of the genus, A. reflexus sp. nov., collected from Kimboza Forest Reserve in Tanzania, and discuss the dubious tribe Trachystreptini.
First records of Elachistinae are given from Thailand. Ten species of Elachistinae are reported, eight of which are described as new: Urodeta longa Sruoga & Kaila sp. nov., Elachista buszkoi Sruoga & Kaila sp. nov., E. oryx Sruoga & Kaila sp. nov., E. pellineni Sruoga & Kaila sp. nov., E. capricornis Sruoga & Kaila sp. nov., E. phichaiensis Sruoga & Kaila sp. nov., E. loeiensis Sruoga & Kaila sp. nov. and E. siamensis Sruoga & Kaila sp. nov. The new species are diagnosed and illustrated with photographs of the adults and genitalia. One species remains unidentified to species level.
In this paper we describe two new tardigrade species belonging to the Macrobiotus hufelandi complex: Macrobiotus noongaris sp. nov. from Perth, Australia, and Macrobiotus kamilae sp. nov. from Mussoorie, India. Live specimens extracted from moss samples were used to establish laboratory cultures in order to obtain additional animals and eggs needed for their integrative descriptions. These descriptions are based on traditional morphological and morphometric data collected using both light and scanning electron microscopy, which, at the same time, were associated with DNA sequences of four genetic markers, three nuclear (18S rRNA, 28S rRNA and ITS-2) and one mitochondrial (COI). The use of DNA sequences allowed for a more accurate verification of the taxonomic status of M. noongaris sp. nov. and M. kamilae sp. nov as independent species of the hufelandi group. Although they both exhibit typical inverted goblet-shaped processes, they represent a recently discovered clade, which was thought to group species with modified morphology of egg processes. Thus, this contribution expands the definition of the mentioned clade and constitutes another link that will be helpful for future studies on the evolution of the M. hufelandi complex.
Twenty-two samples of Leptoclinides Bjerkan, 1905 collected along the Brazilian coast between 1998 and 2017 were examined. Herein we describe two new species (Leptoclinides coronatus sp. nov. and Leptoclinides lotufoi sp. nov.). We also extend the distribution of L. latus F. Monniot, 1983 and report that, for the first time, L. torosus F. Monniot, 1983 was found outside its type locality.
The present study is based on the genus Cotesia Cameron,1891 collected from Khuzestan Province in the Southwestern part of Iran during 2016–2017. Nine species (+200 specimens) of the genus Cotesia were collected and identified. We recognised three new species, which we describe and illustrate here: Cotesia elongata Zargar & Gupta sp. nov., C. khuzestanesis Zargar & Gupta sp. nov. and C. zagrosensis Zargar & Gupta sp. nov. Two species are recorded for the first time from Iran: Cotesia cynthiae (Nixon, 1974) and C. glabrata (Telenga, 1955). A faunistic list with species distribution in Iran, a modified key to include the new species and brief diagnoses for the new records from Iran are provided.
Aronia Medik. (chokeberry, Rosaceae) is a genus of woody shrubs with two or three North American species. Species boundaries and relationships between species of Aronia are frequently under question. The only European species in the genus, A. mitschurinii A.K.Skvortsov & Maitul., is suggested to be an inter-generic hybrid. In order to clarify the relationships between species of Aronia, we performed several morphometric and molecular analyses and found that the molecular and morphological diversity within data on American Aronia is low, and species boundaries are mostly not clearly expressed. Whereas morphology is able to separate American species from A. mitschurinii, there is no support for such discrimination from the molecular data; our analyses did not reveal evidence of A. mitschurinii hybrid origin. We believe that higher-resolution markers are needed to resolve species boundaries and putative hybridization events.
Chondrocyclus Ancey, 1898 is a genus of nine species of African operculate land snails restricted to indigenous forest and mesic thicket. Worn specimens (i.e., without a periostracum or operculum), on which some species descriptions and records were based, appear to be indistinguishable morphologically. A comprehensive revision of Chondrocyclus s.l. is provided here based on comparative morphological examinations of the shell, protoconch, periostracum, operculum, radula and penis, and on mitochondrial genes cytochrome c oxidase subunit I and 16S rRNA. Two genus-level lineages are recognised, Chondrocyclus s.s. and Afrocyclus gen. nov. Revised species descriptions are given for seven species. Two species, C. meredithae Bruggen, 1983 and C. chirindae Bruggen, 1986 both from north of South Africa, are removed from Chondrocyclus. Twelve new species are described: C. herberti sp. nov., C. silvicolus sp. nov., C. amathole sp. nov., C. pondoensis sp. nov., C. devilliersi sp. nov., C. pulcherrimus sp. nov., C. cooperae sp. nov., C. langebergensis sp. nov., C. kevincolei sp. nov., A. oxygala gen. et sp. nov., A. potteri gen. et sp. nov. and A. bhaca gen. et sp. nov. This is the first detailed systematic revision of an Afrotropical cyclophorid group to include morphological and molecular data. This study complements research on other taxa of low-vagility forest-dwelling habitat specialists by providing comparative distribution data for an independent, widespread group. Such evidence is urgently needed for conservation of South Africa’s threatened forest biome.
The world species of Netomocera Bouček, 1954 (Hymenoptera Linnaeus, 1758: Pteromalidae Dalman, 1820), excluding those from the Oriental region, are revised. The Oriental species are excluded because their types could not be examined, the species limits could not be reliably assessed based on original descriptions and available Oriental material was scarce. Eighteen species, including 11 species described as new, are recognized: N. africana Hedqvist, 1971; N. alboscapus Hedqvist, 1971; N. amethysta sp. nov.; N. celebensis sp. nov.; N. cyanocephala sp. nov.; N. desaegeri sp. nov.; N. formiciformis sp. nov.; N. gloriosa sp. nov.; N. irregularis sp. nov.; N. masneri sp. nov.; N. merida sp. nov.; N. meridionalis sp. nov.; N. nearctica Yoshimoto, 1977; N. ramakrishnai Sureshan, 2010; N. rufa Hedqvist, 1971; N. sedlaceki Bouček, 1988; N. setifera Bouček, 1954; N. virgata sp. nov. The female brachypterous form of N. nearctica and the male of N. alboscapus are described for the first time. A key to both sexes is provided, as well as diagnoses, descriptions and illustrations for all treated species. The genus is reported for the first time in the Neotropical region. For several species, new distributional records are also given.
