The second and final part of a revision of the European species of the genus Rhabdomastix Skuse, 1890 is presented. The subgenus Rhabdomastix s. str. is revised. Seven species are redescribed, Rhabdomastix (Rhabdomastix) japonica Alexander, 1924, R. (R.) laeta (Loew, 1873), R. (R.) borealis Alexander, 1924, R. (R.) edwardsi Tjeder, 1967, R. (R.) subparva Starý, 1971, R. (R.) hirticornis (Lackschewitz, 1940) and R. (R.) beckeri (Lackschewitz, 1935). Three new synonyms are proposed. Lectotypes of four pertinent nominal species are designated. Descriptions are provided of six species, viz. R. (R.) laetoidea sp. n. (Czech Republic, Slovakia, Bulgaria, Ukraine), R. (R.) crassa sp. n. (France, Czech Republic, Slovakia), R. (R.) corax sp. n. (Bulgaria, Greece), R. (R.) eugeni sp. n. (France, Switzerland, Germany, Czech Republic, Slovakia, Italy, Romania, Bulgaria, Greece, Ukraine, Armenia), R. (R.) filata sp. n. (Bulgaria, Greece, European Russia, Turkey, Georgia, Armenia) and R. (R.) georgica sp. n. (Georgia). Male and female terminalia are illustrated for all the species, and a key to species is appended.
A new subfamily Homalomitrinae is established for two enigmatic Neotropical genera, Homalomitra Borgmeier, 1931 and Sphaeromitra gen. n. which are diagnosed on the basis of newly discovered characters. All available specimens of the group are revised. Two new species of Homalomitra, H. antiqua sp, n. (Costa Rica, Brazil) and H. tenuior sp. n. (female only; Colombia, Ecuador) are described and the remaining species of the genus, H. ecitonis Borgmeier, 1931 (type species, Brazil) and H. albuquerquei Mourgués-Schurter, 1987 (Costa Rica) are redescribed. A key to Homalomitra species is given. Sphaeromitra inepta gen. et sp. n. is described from Peru. Phylogenetic relationships of Homalomitrinae, both its genera and all species included are discussed.
This study is a revision of the Iberian Merodon Meigen, 1803 species, including an illustrated key, a discussion of taxonomic characters and a morphological diagnosis for all included species. Descriptions are provided for nine new species: M. antonioi sp. n., M. arundanus sp. n., M. cabanerensis sp. n., M. crypticus sp. n., M. hurkmansi sp. n., M. legionensis sp. n., M. longispinus sp. n., M. luteihumerus sp. n. and M. quercetorum sp. n. The taxon M. escorialensis Strobl, 1909 is redescribed and lectotype is designated. Lectotypes are designated for four taxa: M. albifrons Meigen, 1822; M. spinipes obscuritarsis Strobl in Czerny & Strobl, 1909; M. spicatus Becker, 1907; and M. spinipes grossus Gil Collado, 1930. Three varieties are redefined and considered as valid species: M. obscuritarsis Strobl in Czerny & Strobl, 1909 (as var. of spinipes); M. grossus Gil Collado, 1930 (as var. of spinipes); M. unicolor Strobl in Czerny & Strobl, 1909 (as var. of aeneus). The following new synonymies are proposed: M. affinis Gil Collado, 1930 syn.n. (= junior synonym of M. longicornis Sack, 1913); M. lusitanicus Hurkmans, 1993 syn.n. (= junior synonym of M. serrulatus Wiedemann in Meigen, 1822); M. andalusiacus Paramonov, 1929 syn.n., M. bolivari Gil Collado, 1930 syn.n., M. hispanicus Sack, 1931 syn.n. (= all three are junior synonyms of M. unguicornis Strobl in Czerny & Strobl, 1909); M. spicatus Becker, 1907 syn.n. (= junior synonym of M. chalybeus Wiedemann in Meigen, 1822); M. fuerteventurensis Barkemeyer, 2002 syn. n. (= junior synonym of M. obscuritarsis Strobl, 1909); and M. spinipes grossus (Gil Collado, 1930) syn.n. (= junior synonym of M. albifrons Meigen, 1822). Status of M. serrulatus Wiedemann in Meigen, 1822 is revised. Four species: M. longicornis Sack, 1913, M. pumilus Macquart, 1849, M. ottomanus Hurkmans, 1993 and M. segetum (Fabricius, 1794) are new for the Iberian Peninsula. Male genitalia are illustrated for all the species and a key of the 34 Iberian species (+ M. hurkmansi sp. n.) for males and females (except for the unknown female of M. longispinus sp. n.) is appended. Distribution and biological data for the Iberian species are also included. A brief zoogeographic discussion is also presented. The level of endemism of genus Merodon on the Iberian Peninsula is extremely high (almost 50%).
The New World species of Loxocera Meigen are revised including two new species, L. (Imantimyia) ignyodactyla Buck sp. n. from Costa Rica (first record of the genus from the Neotropical region) and L. (Imantimyia) ojibwayensis Buck sp. n. from Ontario, Canada. Loxocera californica Capelle is synonymized with L. collaris Loew and lectotypes are designated for L. pleuritica Loew and L. cylindrica var. obsoleta Johnson (both synonyms of L. cylindrica Say). The New World species are diagnosed and a key to species is provided. The male and female terminalia of Loxocera are described in detail for the first time, and their functional morphology is discussed. Eggs of most species are described and a key to the known eggs of Loxocera is provided. A phylogenetic framework for the Holarctic subgenera and species groups of Loxocera is developed based on morphological characters of the adult flies. The Old World subgenus Platystyla Macquart is synonymized with Loxocera s. str., and Imantimyia Frey is reinstated as a valid subgenus including all Holarctic species previously placed in Loxocera s. str. except the L. aristata species group. This leads to the following new subgeneric combinations: L. (L.) malaisei Frey comb. n., L. (L.) matsumurai Iwasa comb. n., L. (L.) monstrata Iwasa, comb. n., and L. (L.) omei Shatalkin comb. n. The species groups of Imantimyia are redefined, i.e. the L. achaeta-group (7 spp.), the L. fulviventris-group (4 spp.), and the L. albiseta-group (1 sp.). The Oriental subgenus Asiopsila Shatalkin is referred to Psila Meigen s. l. as a subgenus based on characters of the egg, resulting in fourteen new generic combinations: Psila (Asiopsila) brevibuccata (Shatalkin) comb. n., P. (A.) burmanica (Frey) comb. n., P. (A.) decorata (de Meijere) comb. n., P. (A.) derivata (Shatalkin) comb. n., P. (A.) formosana (Hennig) comb. n., P. (A.) freidbergi (Shatalkin) comb. n., P. (A.) humeralis (de Meijere) comb. n., P. (A.) kambaitensis (Frey) comb. n., P. (A.) limpida (Shatalkin) comb. n., P. (A.) maculipennis (Hendel) comb. n., P. (A.) michelseni (Shatalkin) comb. n., P. (A.) pleuralis (Frey) comb. n., P. (A.) primigena (Shatalkin) comb. n., and P. (A.) vittipleura (Shatalkin) comb. n.
The genus Phaeochiton Kerzhner, 1964 is revised and P. alenae sp. n. from Mongolia is described. Differential diagnoses are provided for the genus and its three species. Illustrations of male and female genitalia, tarsus and pretarsus, photographs of the dorsal habitus, hosts, and distributional records of the species discussed are given.
The bee family Melittidae (Hymenoptera: Apoidea) includes 14 genera. Most have been reviewed but not the small African genus Capicola. The present work aims to fill this gap. Based on the revision of the type material and 1272 additional specimens, we provide a comprehensive synonymic and annotated catalogue of the 12 Capicola species sensu Michener (1981). Lectotypes are designated for the previously established species Capicola braunsiana (= C. obscura syn. n.), C. cinctiventris, C. femorata, C. flavitarsis and C. rufiventris. Moreover, C. danforthi sp. n., C. flavicara sp. n., C. gessorum sp. n., C. micheneri sp. n., and C. richtersveldensis sp. n., are newly described, as well as the previously unknown female of C. nanula, male of C. nigerrima and male of C. rhodostoma. New synonymies are proposed for C. braunsiana (= C. obscura) and C. flavitarsis (= C. cinctiventris). An original dataset of 20 morphological characters is used for the inference of the 12 species' phylogenetic relationship. A key to species is provided. In addition, the ranges of the 12 taxa are mapped and discussed. This paper contributes to a global revision of the Melittidae.
The species of the mylabrine genus Mimesthes are revised and a new species (M. karooensis) is described from the South African Karoo. The systematic position of the genus is also discussed and an identification key to the species is proposed. Geographical distribution and habitat preferences, as well as other bionomic features, are summarised.
The blister beetle genus Teratolytta, belonging to the tribe Lyttini, is revised and a classification is proposed. Two main sections of the genus - one including five groups of species and the other three groups - are tentatively defined. Four new species from Eastern and Southern Anatolia are described (T. carlae sp. n., T. dvoraki sp. n., T. monticola sp. n., T. taurica sp. n.), and a key to the 17 recognized species is proposed. A diagnosis of the species as well as taxonomic remarks are proposed, and a catalogue of localities is presented. In particular, Teratolytta tricolor (Haag-Rutenberg, 1880) comb. n. is re-established as a distinct species, T. cooensis G. Müller, 1936 is confirmed as a synonym of T. gentilis (Frivaldszky, 1877), T. bytinskii Kaszab, 1957 as a synonym of T. senilis (Abeille de Perrin, 1895), and T. holzschuhi Dvořák, 1983 is proposed as a synonym of T. eylandti Semenow, 1894; some infraspecific forms are referred to the variability of T. gentilis and T. flavipes (Mulsant & Rey, 1858). The first instar larva of T. gentilis is described and figured, and the sexual behaviour of this species is also briefly studied.
A revision of the genus Wakarumbia Bocák, 1999 from Sulawesi is presented. Altogether 10 species are included in the genus Wakarumbia: the type species W. gracilis Bocák, 1999 is redescribed, a new combination of Wakarumbia celebensis (Kleine, 1933) is proposed (originally placed in Protaphes Kleine, 1926) and the following new species are described: Wakarumbia brendelli sp. n., W. brunnescens sp. n., W. flavohumeralis sp. n., W. grandis sp. n., W. nigra sp. n., W. oculata sp. n., W. pallescens sp. n. and W. similis sp. n. The important diagnostic characters are illustrated and all species are keyed. Relationship between species and ecological data are briefly discussed.
The Oriental helotrephid genus Idiotrephes Lundblad, 1933, is taxonomically revised. Species discrimination is based on male genitalia and female terminalia. Three species groups are recognized. The I. chinai group contains I. chinai Lundblad, 1933 (type species; from Sumatra, Borneo, and West Malaysia) and three newly described species; I. asiaticus sp. n. (from Vietnam, Thailand, and west Malaysia); I. yupae sp. n., and I. polhemusi sp. n. (both from Thailand). The I. maior group contains I. maior Papáček, 1994; I. meszarosi Papáček, 1995 (both from Vietnam), and I. hainanensis sp. n. (from Hainan, China). The I. thai group consists of two newly described species from north and northeast Thailand, I. thai sp. n. and I. shepardi sp. n. In addition, some features of biology and morphology of the ovipositor are also included.
