The Pacific mealybug genus Laminicoccus Williams is reviewed. At present six species are assigned to the genus including a new species, Laminicoccus samoanus sp. nov., described from Western Samoa. Most of the host-plant records of these mealybugs are from monocotyledons and many of the species seem to prefer plants belonging to the families Arecaceae, Pandanaceae, and Poaceae. One or two host-plant records, nevertheless, are from dicotyledons. A key to species of Laminicoccus is provided. The mealybug Pseudococcus pandanicola Takahashi, described originally from Palau, had been included in Laminicoccus but is here reassigned to Pseudococcus and redescribed.

Rhagoletis antioquiensis Rodriguez & Norrbom, a new species of fruit fly in the striatella species group of Rhagoletis Loew, is described and illustrated. New distribution records are reported for two other species of the striatella group: R. nicaraguensis Hernández-Ortiz & Frías, 2000 is reported from Costa Rica, and R. solanophaga Hernández-Ortiz & Frías, 2000 from Bolivia. A lectotype is designated for Urophora scutellaris Macquart, 1851 (= R. macquartii (Loew)). New host plant relationships for three species of Rhagoletis, all reared from fruits, are reported: Acnistus arborescens (L.) Schrtdl. and Witheringia solanacea L’Her for R. jamaicensis Foote, 1981 from Colombia; Lycianthes pseudolycioides (Chod. & Hassl.) Bitter for R. solanophaga from Bolivia; and Solanum pseudocapsicum L., Solanum tuberosum L. subsp. andigenum (Juz. & Burkasov) Hawkes, Solanum interandinum Bitter from Colombia and Solanum americanum Mill. in Peru for undetermined species of the psalida group. The key to species of the striatella group of Hernández-Ortiz & Frías (2000) is modified to include R. antioquiensis.

We describe and illustrate Magnolia mixteca, a new species of Magnolia sect. Macrophylla from the Alto Balsas Basin in Oaxaca, Mexico, providing information about its ecology, biogeography and conservation status. Magnolia mixteca differs from M. nuevoleonensis in having larger flowers, longer petals, a yellow petal-blotch, a tan-sand coloured ovary and more numerous stamens and carpels. In addition, we provide a distribution map and key to species of sect. Macrophylla. The relict distribution of this species allows us to consider it endangered (E).

A new species of Fidelia Friese, 1899 is described from southern Africa: Fidelia (Fideliopsis) whiteheadi Litman & Kuhlmann sp. nov. Diagnostic characters are provided to distinguish this species from others in the genus, particularly from the closely related F. hessei; an updated description for Fidelia hessei is also given. The host plant preferences and seasonal activity of F. whiteheadi Litman & Kuhlmann sp. nov. and F. hessei are discussed. Finally, a revised, illustrated key to species of the genus Fidelia is presented.

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.

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.
