AbstractFive species of the subfamily Acrolobinae, viz. Panagrolobus vanmegenae gen. n., sp. n., Teratolobus regulus Andrássy, 1968, T. obscurus sp. n., T. hamatus (Andrássy, 1986) comb. n. and T. similis sp. n., are described and illustrated from material collected in The Netherlands, Ukraine, Costa Rica, Mexico, Australia and South Africa. The new genus is characterised by a crown-shaped labial region with six well-developed, leaf-like lips having a biradial symmetry; lips separated by narrow and internally sclerotised U-shaped clefts; lateral lips half as wide as the subdorsal and subventral ones; a broad anisomorphic stoma; strongly sclerotised, hookshaped, cheilorhabdia; a strongly developed dorsal prostegorhabdion extending inside the stegostom cavity; a conoid tail with a rounded terminus bearing a dorsally curved, hook-like, mucro; and phasmids located at 70-90% of tail length. Teratolobus obscurus sp. n. is distinguished from the closely related T. regulus by the following characters: a smaller spermatheca (7.0-14.5 vs 26-61 μm); a shorter PUB (12-19 vs 18-42 μm); a shorter female tail (42-50 vs 55-72 μm); and differently shaped mucro on the tail terminus (harpoon-like vs hook-like). Teratolobus similis sp. n. is distinguished from the closely related T. baloghi (Andrássy, 1986) comb. n. by the following characters: a smaller body (350-420 vs 470-480 μm); a shorter PUB (9-12 vs 35-38 μm; 0.5-0.8 vs ca. 2 VBD long); shorter female tail (41-53 vs 62-65 μm; c′ = 3.4-5.4 vs 6.5-7.0); and differently shaped mucro on the tail terminus (arrowhead-like vs finely forked). Based on current research, a revision is proposed of the taxonomy of the genus Teratolobus and the subfamily Acrolobinae. The following new combinations are proposed: Teratolobus baloghi; T. hamatus; and T. occultus (De Ley & Coomans, 1990) comb. n. Panagroteratus is proposed as a synonym of Teratolobus.

In the paper described are two new species of the genus Amphicrossus Erichson, 1843 (A. microtuberculatus sp. nov. from Sudan and A. uhligi sp. nov. from Zambia: Amphicrossinae), one new species of the genus Meligethinus Grouvelle 1906 (M. zimbabwensis sp. nov. from Zimbabwe: Meligethinae), one new species from the genus Neopallodes Reitter, Reitter, 1884 (N. madagascarensis sp. nov. from Madagascar: Nitidulinae, Cyllodini) and one species of the new genus Gonoglypha gen. nov. (G. distinctissima sp. nov. from Australia (Queensland): Nitidulinae, Cychramptodini). In the paper also some addition to the description of Meligethinus dolosus Grouvelle, 1919 from the eastern part of South Africa and some comments on significance of different characters, taxonomy and classifications of some groups of the family Nitidulidae are included.

Within the framework of a taxonomic revision of subfamily Urgineoideae based on morphological, genetic and phytogeographic data covering numerous samples from its whole range of distribution, we here describe a new genus and species from Pella se Berge in northwestern South Africa. Triandra gen. nov. is easily characterized by the absence of stamens associated with the outer tepal whorl, therefore having only three stamens per flower, a character previously unknown in Hyacinthaceae. Triandra pellabergensis sp. nov. produces hypogeal bulbs with filiform proteranthous leaves, spurred bracts, lax racemes with few, nodding, nocturnal flowers and erect capsules with the withered tepals persisting atop. The new species resembles Urginea revoluta in general morphology, although this latter species has six stamens per flower, a different seed morphology, a distinct phytogeographic pattern, and a distant phylogenetic relationship. A complete morphological description is presented for the new genus and species, including data on its biology, ecology and distribution.

A new genus and species, Unguitarsonemus paradoxus n. gen., n. sp. and a new species, Pseudotarsonemoides peruviensis n. sp. (Acari: Trombidiformes: Tarsonemidae), are described based on phoretic females collected on bark beetles Phloeotribus pilula and Ph. biguttatus, respectively, from Peru. A key to species of the genus Pseudotarsonemoides is provided.

Namaquaropus niger gen nov. & sp.nov. is described from South Africa. In addition, two new species of the subgenus Jehania Distant of Isometopus Fieber (I. mirus sp. nov. and I. maculipennis sp. nov.), and Paloniella flavicolor sp. nov. are described. With these, the known species of Isometopinae in South Africa now number sixteen.

Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

The early Miocene site of Wadi Moghra, Qattara Depression, Egypt, is important for interpreting anthracothere (Mammalia, Artiodactyla) evolution, because the Moghra sediments preserve a higher diversity of anthracotheres than any other pene-contemporaneous site. New specimens from Moghra are described and form the basis for the systematic revision of Moghra anthracotheres provided here. Among the important discoveries recently made at Moghra is the first complete skull of Sivameryx moneyi. Other new specimens described here include two new species of Afromeryx, and a new genus and species, all of which are unique to Moghra. A review of biogeographic information supports the conclusion that three of the Moghra anthracotheres (Brachyodus depereti, B. mogharensis, and Jaggermeryx naida, n. gen. n. sp.) are members of late surviving lineages with a long history in Africa, while three other species (Afromeryx grex, n. sp., A. palustris, n. sp., and Sivameryx moneyi) represent more recent immigrants from Eurasia.

Ptychocroca, new genus, is described and illustrated. As presently defined, the genus includes eight species: P. apenicillia, new species, from Chile; P. nigropenicillia, new species, from Chile; P. lineabasalis, new species, from Chile; P. keelioides, new species, from Chile; P. simplex, new species, from Chile; P. crocoptycha (Meyrick), new combination, from Argentina and Chile; P. wilkinsoni (Butler), new combination, from Chile; and P. galenia (Razowski), new combination, from Chile. We present brief diagnoses for the related genera Apotomops Powell and Obraztsov, Bonagota Razowski, Haemateulia Razowski, and Acmanthina Brown, along with descriptions of two new species of Apotomops (A. boliviana and A. spomotopa, new species). We also propose two new combinations, Apotomops carchicola (Razowski and Becker) and A. sololana (Razowski), and the synonymy of Bonagota cranaodes (Meyrick) with B. salubricola (Meyrick).
