Abstract: Nearctic Anthomyzidae of the Anthomyza clade comprising the genera Fungomyza
Roháček, 1999 (1 species), Ischnomyia Loew, 1863 (1 species), Arganthomyza
Roháček, 2009 (7 species) and Anthomyza Fallén, 1810 (18 species) are
monographed. A review of the history of taxonomic research of the Nearctic
Anthomyzidae and of the adult morphology are given. All included taxa are
treated systematically, with complete data on nomenclature, type material,
taxonomy (diagnoses and (re)descriptions, keys, illustrations of taxonomically
important structures), relationships, biology and distribution. The concept of
Ischnomyia is redefined and its Nearctic species are revised and redescribed as
are all those of Anthomyza; species of the remaining two genera are reviewed.
Ischnomyia spinosa Hendel, 1911 syn. nov., is a new junior synonym of
Arganthomyza vittipennis (Walker, 1857) comb. nov., the latter being resurrected
from synonymy with Ischnomyia albicosta (Walker, 1849), transferred to
Arganthomyza and redescribed. The E. Palaearctic species I. barbarista
(Roháček, 2009) comb. nov. is excluded from the genus Arganthomyza and
transferred to Ischnomyia. Fifteen new species of Anthomyza are described, viz.
A. oblonga, A. silvatica, A. pengellyi, A. mcalpinei, A. pullinotum, A.
occidentalis, A. vockerothi, A. dichroa, A. gibbiger, A. orthogibbus, A.
shewelli, A. gilviventris, A. furvifrons, A. vulgaris, A. equiseti spp. nov. and
remaining 3 species are redescribed, viz. A. tenuis (Loew, 1863), A. variegata
(Loew, 1863) and A. concolor (Thomson, 1869). One neotype (of I. albicosta) and
5 lectotypes are designated. Species groups are redefined and rediagnosed
within the genera Arganthomyza and Anthomyza, while the Arganthomyza vittipennis
group and Anthomyza tschirnhausi group are newly established. The first modern
key to all Nearctic genera of Anthomyzidae is provided. Distributional patterns
of species studied are presented using a coarse measure of dissimilarity.
Relationships of taxa under study are discussed following a new phylogenetic
hypothesis based on cladistic analysis of morphological data of all known
species in the Anthomyza clade.
