Hitherto, the Paleogene fossil genus Acartophthalmites Hennig, 1965 included only the type species, A. tertiaria Hennig, 1965, from Baltic amber (Eocene, ca. 40 Mya). An additional species, Acartophthalmites clusioides sp. nov., is described based on a well preserved male in a Baltic amber inclusion from Kaliningrad: Yantarny (Russia). It distinctly differs from A. tertiaria in a number of characters demonstrating that the genus Acartophthalmites is morphologically more diverse than considered previously. Moreover, the study of A. clusioides resulted in finding that Acartophthalmites is obviously not related to Acartophthalmidae (where it was originally affiliated), but seems to be closer to Clusiidae, although surely not belonging to the latter family as currently delimited. Therefore a revision of all available specimens of Acartophthalmites is suggested to gain a more complete set of morphological data of this genus, enabling analysis of its phylogenetic relationships. © 2016, National Museum/Narodni muzeum.

A hypothesis of phylogenetic relationships of mainly Holarctic Anthomyzidae based on multigene analysis of combined mitochondrial + nuclear gene markers is compared with those of previously published cladistic analyses of morphological characters with the aim to elucidate affinities of phylogenetically unsettled taxa. The placement of Fungomyza Roháček, 1999, Amygdalops Lamb, 1914 + Typhamyza Roháček, 1992 and Quametopia Roháček & Barber, 2011 + Paranthomyza Czerny, 1902 proved to be well supported by molecular data but are inconsistent with those suggested by morphological data analyses, therefore demanding further phylogenetic study. In other groups, the relationships recognized by multigene molecular analysis are in agreement with previous or subsequent morphological examination: the Mumetopia nigrimana group is postulated as the closest ally of Stiphrosoma Czerny, 1928 and hence needs to be excluded from Mumetopia Melander, 1913; intrageneric relationships of Arganthomyza Roháček, 2009 and allies revealed that Ischnomyia spinosa Hendel, 1918 is, in fact, a species of Arganthomyza and that the concept of the genus Ischnomyia Loew, 1863 has to be redefined; Epischnomyia Roháček, 2006 proved to be closest to Anthomyza Fallén, 1810. The placement of the genera Anagnota Becker, 1902, Carexomyza Roháček, 2009, Cercagnota Roháček & Freidberg, 1993 and Santhomyza Roháček, 1984 have not been resolved either by molecular or morphological analyses and their sister groups remain unknown. The new molecular evidence provides new insight into the phylogeny of Anthomyzidae, but like morphology, fails to resolve some key nodes, suggesting that new studies using both sources of information will be necessary to fully reconstruct the history of the family. © Senckenberg Gesellschaft für Naturforschung, 2014.

Quametopia gen. n. is established on the basis of recent phylogenetic analysis of taxa formerly assembled under the genus Mumetopia Melander, 1913 to include M. terminalis (Loew, 1863) and two new closely related Nearctic species of Anthomyzidae. The new genus is diagnosed and its phylogenetic relationships discussed. Quametopia terminalis (Loew, 1863) comb. n. is transferred from Mumetopia and redescribed based on revision of the type material (lectotypes of Anthophilina terminalis Loew, 1863 and its synonym Mumetopia nitens Melander, 1913 are designated) and other extensive material. Quametopia clintonia sp. n. and Q. amplistylus sp. n. (both from Canada, USA) are described and relationships of all three Quametopia species discussed. Immature stages of Q. terminalis and Q. clintonia sp. n. obtained by means of adult-to-adult rearing are described (1st- and 2nd-instar larvae for the first time in the family Anthomyzidae) and illustrated. Keys to adults, eggs, larvae and puparia of Quametopia species are presented. Biology (habitat and host-plant associations, life history) of Q. terminalis and Q. clintonia sp. n. are studied in detail and their ecological separation demonstrated. Distribution of all Quametopia species is reviewed.

The taxonomy and nomenclature of the family Sphaeroceridae (Diptera: Acalyptratae) is reviewed in the context of a world catalog and bibliography covering the last decade (2000-2010). Bispinicerca Su & Liu, 2009, syn. nov., is synonymized with Opacifrons Duda, 1918 and the following new combinations are given: Opacifrons liupanensis (Su & Liu, 2009), comb. nov., Pseudopterogramma annectens (Richards, 1964), comb. nov., Pseudopterogramma brevivenosum (Tenorio, 1967), comb. nov., and Pseudopterogramma conicum (Richards, 1946), comb. nov. Thirty genera and 211 species were added to the family between 2000 and 2010, giving a current total of 141 genera and 1,550 species. A gallery with 32 macrophotographs is provided, depicting 32 species of 30 genera representing 3 subfamilies of Sphaeroceridae. A world bibliography of Sphaeroceridae is supplemented with 306 references.

Rediscovery of Rhabdomastix (Rhabdomastix) incapax Starý, 2005 in Sardinia made it possible to update the description of the male and to provide the first description of the female of this species. Notes on the wing reduction, ecology, and behaviour of this species are appended. © Jaroslav Starý and Jindrich Rohácek.
