AbstractIllustrated descriptions of galls, larvae, pupae and adults, with a diagnostic key, are given for five species of Psectrosema Kieffer (= Amblardiella Kieffer = Isosandalum Kieffer) collected from various species of Tamarix during field surveys of potential biocontrol agents undertaken by the Commonwealth Institute of Biological Control in Pakistan. The genus Psectrosema is re-defined and the eleven species previously described from Europe, North Africa, India and Kazakhastan, USSR, are listed, mostly as new combinations. The five species recorded from Pakistan are P. manü nom. nov., stat. rev., comb. n. (= tamaricis Mani) from T. dioica; P. indicum sp.n. from T. indica; P. reticulatum sp.n. from T. hispida, T. androssowii and T. arceuthoides; P. unicornis sp.n. from T. dioica; and P. parvum sp.n. from T. indica.

A New Species

Monolophus odontochilus Y.H.Tan & H.B.Ding, a new species from Northern Myanmar, is described and illustrated. The new species is morphologically similar to M. linearis, but differs by having elliptic to oblong leaves (vs. linear-lanceolate to lanceolate), bilobed ligules (vs. entire), purely white corolla (vs. pinkish white), semi-orbicular crenate labellum (vs. trilobed). In addition, a diagnostic key to the new species of Monolophus and its closely related non-yellow flowered species is provided. New combinations are proposed here for Caulokaempferia phokhamii Picheans. & Douangde. and C. wongsuwaniae Picheans. & Douangde. from Laos.

All available material of fossil Bibionidae from French Oligocene localities, including the German locality of Kleinkembs right next to the border with France, is revised, and the species redescribed. Several publications (notably Heer 1856, Oustalet 1870 and Théobald 1937) have dealt with this material but there is a large degree of duplication leading to numerous synonyms. In addition, many of the named species have been assigned to the wrong genus. We have found seven species of Penthetria, eleven species of Plecia, seven species of Bibio and a single species of Dilophus in the material of previously named species. Three new species, Penthetria luberonica sp. n., Bibio aquaesextiae sp. n. and Bibiodes provincialis sp. n. are described from French Oligocene localities. The following new combinations are proposed: Penthetria claripennis (Théobald, 1937), Penthetria gigantea (Théobald, 1937), Penthetria graciliventris (Théobald, 1937), Penthetria longiventris (Théobald, 1937), Penthetria nervisinuata (Théobald, 1937), Penthetria subterranea (Théobald, 1937), Plecia morio (Heer, 1849), Bibio major (Oustalet, 1870), Dilophus luteipennis (Théobald, 1937). Many of the species occur from several outcrops, and distinctive faunas can be recognized from Early Oligocene (e.g., Célas and Monteils), Middle Oligocene (e.g., Céreste and Bois d’Asson) and Late Oligocene (e.g. Aix-en-Provence and the German outcrop of Rott). The late Oligocene localities also share some species with the Early Miocene locality of Radoboj, Croatia, but none with the younger locality of Öhningen, Southern Germany. For a number of named species, the type material is poorly preserved and cannot be recognized at the species level, these are commented on and assigned to the lowest taxonomical level to which they can be identified with certainty. The type materials of a number of species appear to be lost; these are placed to genera to the extent that this is possible from the original descriptions and illustrations. Bibio nigripennis Théobald, 1937, nec Brunetti, 1913 is a primary junior homonym and the name must be replaced. The species is moved to the genus Plecia and renamed Plecia theobaldi nom.n.

Leptobrachella (Anura: Megophryidae) is currently composed of seventy-one species distributed in China and Southeast Asia (Frost 2018). Fourteen species of Leptobrachella are currently known from southern China: L. alpina (Fei, Ye & Li, 1990), L. laui (Sung, Yang & Wang, 2014), L. liui (Fei & Ye, 1990), L. mangshanensis (Hou, Zhang, Hu, Li, Shi, Chen, Mo & Wang, 2018), L. maoershanensis (Yuan, Sun, Chen, Rowley & Che, 2017), L. oshanensis (Liu, 1950), L. purpura (Yang, Zeng & Wang, 2018), L. tengchongensis (Yang, Wang, Chen & Rao, 2016), L. wuhuangmontis (Wang, Yang & Wang, 2018), L. yingjiangensis (Yang, Zeng & Wang, 2018), L. yunkaiensis (Wang, Li, Lyu & Wang, 2018), L. ventripunctata (Fei, Ye & Li, 1990), L. pelodytoides (Boulenger, 1893) and L. sungi (Lathrop, Murphy, Orlov & Ho, 1998) and the first eleven species are endemic of this region (AmphibiaChina 2018). Many new species in this genus were discovered based on molecular, morphometric and bioacoustic data in recent years (Frost 2018). In comparison to molecular and morphological data, bioacoustics is especially useful in species identification of Leptobrachella in field surveys (Rowley et al. 2016). Although the advertisement calls of many Leptobrachella species were described along with the species descriptions (e.g., Rowley et al. 2016), the advertisement calls of only three Chinese endemic species (L. alpinus; L. laui and L. oshanensis) are known (Jiang et al. 2002; Matsui 2006; Xu et al. 2005). Here, we describe the advertisement calls of L. liui, which inhabits rocky streams in southeastern China (Fujian, Jiangxi and Zhejinag) and is morphologically diagnosed by the combination of a set of external color traits (Fig. 1).

With the global rise of human-mediated translocations and invasions, it is critical to understand the genomic consequences of hybridization and mechanisms of range expansion. Conventional wisdom is that high genetic drift and loss of genetic diversity due to repeated founder effects will constrain introduced species. However, reduced genetic variation can be countered by behavioral aspects and admixture with other distinct populations. As planned invasions, classical biological control (biocontrol) agents present important opportunities to understand the mechanisms of establishment and spread in a novel environment. The ability of biocontrol agents to spread and adapt, and their effects on local ecosystems, depends on genomic variation and the consequences of admixture in novel environments. Here we use a biocontrol system to examine the genome-wide outcomes of introduction, spread, and hybridization in four cryptic species of a biocontrol agent, the tamarisk beetle (Diorhabda carinata, D. carinulata, D. elongata, and D. sublineata), introduced from six localities across Eurasia to control the invasive shrub tamarisk (Tamarix spp.) in western North America. We assembled a de novo draft reference genome and applied RADseq to over 500 individuals from laboratory cultures, the native ranges, and across the introduced range. Despite evidence of a substantial genetic bottleneck among D. carinulata in N. America, populations continue to establish and spread, possibly due to aggregation behavior. We found that D. carinata, D. elongata, and D. sublineata hybridize in the field to varying extents, with D. carinata x D. sublineata hybrids being the most abundant. Genetic diversity was greater at sites with hybrids, highlighting potential for increased ability to adapt and expand. Our results demonstrate the complex patterns of genomic variation that can result from introduction of multiple ecotypes or species for biocontrol, and the importance of understanding them to predict and manage the effects of biocontrol agents in novel ecosystems.

Based on field observation and extensive herbarium studies, a comprehensive taxonomic revision of the genus Pogostemon in China was carried out. Twenty-seven species and two varieties are recognized, among of which eleven species and one variety are endemic to China. A new species, P. henanensis, is described and illustrated. Two new combinations, P. glaber var. tsingpingensis and P. latifolius, are proposed. Six names are reduced to synonymy, eleven names are lectotypified and a name is neotypified. The record of P. menthoides in China is corrected as P. fraternus. One species, P. pressii, is listed as dubious species in China. In addition, nomenclature, descriptions and distribution maps of each species and variety as well as a key to Chinese Pogostemon taxa are presented.

Nomenclatural and taxonomical considerations on Kali, a controversial genus recently segregated from the polyphyletic Salsola s. lat. (Chenopodiaceae), are provided. The Kali group includes annual plants with leaves ending in a spine and lacking hypodermis, having also a cortex alternate to longitudinal chlorenchymatous striae. The species belonging to this genus mainly have a paleotemperate distribution (Europe, Asia and North Africa), occurring as aliens in North America, Australia and South Africa. A new species collected on Mt. Etna (Sicily), and closely related to K. australe, is described and illustrated as K. basalticum Its morphological and molecular features, karyology (2n=54), ecology, distribution, phylogeny and conservation status are examined. In addition, a list of the currently known species of Kali is provided, with some new combinations: Kali nepalense (Grubov) comb. nov., Kali pellucidum (Litvinov) comb. nov., Kali sinkiangense (A.J. Li) comb. nov., Kali gobicolum (Iljin) comb. nov., and Kali ryanii (G.F. Hrusa & Gaskin) comb. nov.
