SummaryA synopsis of Plagiocheilus (Compositae: Astereae) is provided, giving full synonymy, type citations and the location of known types, together with relevant notes and commentary, and the currently accepted distribution of each taxon; the distribution of taxa is also tabulated. Six species are recognised, one containing three subspecies. A key to species is presented. One author citation is corrected following an incorrect assumption by de Candolle when describing Plagiocheilus tanacetoides. The synonymy of Polygyne inconspicua, under Eclipta prostrata, is précised once again. An index to names associated with Plagiocheilus is given, and the nomen nudum of Plagiocheilus herzogii commented upon.

The Neotropical thread-legged bug genus Ghilianella Spinola, 1850 is the most diversified within Metapterini. A taxonomic revision of Ghilianella is presented, in which seventy seven species are recognized as valid, with twenty-one described as new: Ghilianella berengeri sp. nov.; Ghilianella bifurcata sp. nov.; Ghilianella bolivari sp. nov.; Ghilianella caldensis sp. nov.; Ghilianella dilatata sp. nov.; Ghilianella embera sp. nov.; Ghilianella fernandezi sp. nov.; Ghilianella ferruginosa sp. nov.; Ghilianella gilsantanai sp. nov.; Ghilianella goliath sp. nov.; Ghilianella gracilis sp. nov.; Ghilianella huaorani sp. nov.; Ghilianella jaguar sp. nov.; Ghilianella laticauda sp. nov.; Ghilianella maricruzae sp. nov.; Ghilianella quimbaya sp. nov.; Ghilianella scimitarra sp. nov.; Ghilianella tica sp. nov.; Ghilianella urbanoi sp. nov.; Ghilianella ventrimaculata sp. nov.; and Ghilianella weirauchae sp. nov. For the first time a female specimen is described for Ghilianella atriclava Bergroth, 1911, Ghilianella colona McAtee & Malloch, 1925 and Ghilianella pachitea McAtee & Malloch, 1925. Three new synonyms are recognized: Ghilianella bulbifera Champion, 1898 (=Ghilianella pendula McAtee & Malloch, 1925 syn. nov.; Ghilianella inflata Maldonado, 1981 syn. nov.) and Ghilianella strigata McAtee & Malloch, 1925 (=Ghilianella fenestrata Maldonado, 1960 syn. nov.). Eleven species are considered nomina dubia and one species nomen nudum. A key to species and digital images of the external morphology and genitalic structures for each species are provided. Additionally, we offer the first phylogenetic hypothesis of relationships within Ghilianella, using cladistic methods. Based on the phylogenetic results we dismiss all subgenera in Ghilianella and discuss the complex evolution of the abdominal expansions.

AbstractThe spittlebug genus Paracercopis Schmidt is revised. Five species are recognised: P. atricapilla (Distant) comb. n.; P. bicolor sp. n. (Yunnan Province, China); P. darjilingi (Lallemand); P. fuscipennis (Haupt); and P. seminigra (Melichar) (type species). A key to species is given and all species are described and illustrated with their distributional data provided. One new generic synonymy and three new specific synonymies are presented: Paracercopis Schmidt = Esakius Ôuchi; P. atricapilla (Distant) comb. n. = E. chekiangensis Õuchi = P. transversa Lallemand & Synave, P. fuscipennis (Haupt) = E. sinensis Ôuchi. Four lectotypes are newty designated. Paracercopis fusca (Melichar) is returned to Eoscarta Breddin. Paracercopis duplicinigra Jacobi is treated as a nomen nudum.

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.

Seven new species of the genus Zhengitettix Liang, 1994 are described: Z. hosticus sp. nov., Z. mucronatus sp. nov. and Z. spinulentus sp. nov. from Vietnam; Z. albitarsus sp. nov. and Z. extraneus sp. nov. from Thailand; Z. palawanensis sp. nov. and Z. taytayensis sp. nov. from the Philippines. Two species, Z. curvispinus Liang, Jiang et Liu, 2007 and Z. obliquespicula Zheng et Jiang, 2005 are firstly recorded from Vietnam. An annotated check-list and key to species of the genus Zhengitettix are given. Position of Zhengitettix within the family Tetrigidae is briefly discussed.

A review of species of the genus Blera Billberg, 1820 known from China is given. A new species, Blera longiseta sp. nov., is described. Three species, B. japonica (Shiraki, 1930), B. nitens (Stackelberg, 1923) and B. violovitshi Mutin, 1991, are recorded for the first time from China. An illustrated key to species is provided.

Two braconid genera from the subfamily Alysiinae, Lodbrokia Hedqvist, 1962 and Asyntactus Marshall, 1898, are recorded in the fauna of Russia and in the Asian continent for the first time. A new species Lodbrokia uralica sp. nov. is described from the Urals, and a key to species of this genus is provided. Redescriptions of the female and male of Asyntactus rhogaleus Marshall, 1898 with information about the level of variability of its morphological characters are given. Asyntactus sigalphoides Marshall, 1898 is synonymised with A. rhogaleus Marshall, 1898 (syn. nov.).

Abstract Coomansus batxatensis sp. nov., recorded from Vietnam, is described and illustrated and its phylogenetic relationship within the Mononchida is analysed. The molecular data (18S and 28S ribosomal DNA) are provided for the new species. The new species is characterized by small body size (body length, L = 0.7–0.9 mm); buccal cavity sub-rectangular in shape, flattened at base, 21–24 × 12–13 μm or 1.9 (1.7–2.0) times as long as wide; posterior position of dorsal tooth apex (59–63% from the base of buccal cavity); pars refringens vaginae with faint and small (2.5 × 1.7 μm) teardrop-shaped pieces, short pars distalis vaginae; and males with short spicules (50–51.5 μm) with rounded head and conical blade part. The new species is close to Coomansus parvus but differs from it by the smaller buccal cavity size, more posterior position of the dorsal tooth apex, longer tail and presence of males. An updated identification key to Coomansus species and a compendium of all the species known are presented.
