AbstractThe allocation of species to species groups within the genus Bombylisoma Rondani by previous authors is discussed and examined by means of phylogenetic analysis. Most characters previously used to define species groups are shown to exhibit a high degree of homoplasy but characters of the male genitalia provide synapomorphies uniting groups of species. As a result of the analysis a new genus Eremyia gen. n. is proposed for B. argentatum (Greathead) and allied species and species groups are defined: a B. minimum (Scopoli) group; a B. senegalense (Macquart) group; a B. tripunctatum (Macquart) group; and a B. argyropygum (Wiedemann) - B. nucale (Bezzi) group. A key is provided for the identification of the Afrotropical species. B. pectorale (Loew) and B. gibbicorne (Bezzi) are shown to be synonyms of B. senegalense (Macquart), and B. twiga sp. n. is described from Kenya.

Phylogenetic Revision

AbstractA phylogenetic revision of the Neotropical riodinid genus Calydna Doubleday and relatives is presented. A phylogenetic analysis for all twenty species of Calydna using thirty-eight characters of adult morphology generated four most parsimonious cladograms. Calydna is characterised to contain eighteen species, divided here into three monophyletic species groups with the relationship caieta group + (thersander group + hiria group). A new genus Echydna Hall gen. n. is described for the most basal clade, containing chaseba Hewitson and punctata C. & R. Felder, which are transferred from Calydna (combs. n.). The taxonomy, morphology, biogeography and biology of both genera are discussed, locality data is listed and mapped, and the adults and male and female genitalia are illustrated for all species. Concealed male abdominal androconial scales, which phylogenetically unite the thersander and hiria groups, are reported for the first time outside of the tribes Symmachiini and Nymphidiini. Two new species are described, Calydna jeannea sp. n. and Calydna nicolayi sp. n., and the replacement name fissilisima is provided for the unavailable name fissilis Stichel; maculosa Bates is transferred from Calydna to Callistium Stichel (comb. n.).

The genus Sulabanus gen. nov. is described from Sulawesi and it is placed in the tribe Metriorrhynchini, and a close relationships with Metriorrhynchus Gemminger & Harold, 1869 is suggested. Twenty–five species are recognized, of which 24 are described as new: S. ambangensis sp. nov., S. amporiwensis sp. nov., S. barclayi sp. nov., S. brancuccii sp. nov., S. brunneus sp. nov., S. cordatus sp. nov., S. dumongabonensis sp. nov., S. gracilis sp. nov., S. katarinae sp. nov., S. lalui sp. nov., S. lineatus sp. nov., S. mamasensis sp. nov., S. major sp. nov., S. minor sp. nov., S. nigricordatus sp. nov., S. niger sp. nov., S. ocularis sp. nov., S. pendolensis sp. nov., S. robustus sp. nov., S. rufomarginatus sp. nov., S. similis sp. nov., S. tenggahensis sp. nov., S. ulci sp. nov., and S. utarensis sp. nov. Xylobanus nigricolor Pic, 1922 is transferred to Sulabanus gen. nov. and redescribed. The species of Sulabanus are classified in five species groups based on the shape of male genitalia and these groups are described with important diagnostic characters illustrated. A species identification key for males is provided. The ecology, zoogeography, evolution and mimicry of Sulabanus gen. nov. are discussed. The high degree of external similarity among distantly related species from several lycid genera in Sulawesi suggests evolution of Müllerian mimicry.

A new genus of Neotropical Lycidae, Currhaeus gen. nov., is herein proposed as the second Eurrhacini genus lacking parameres in male genitalia. Seven new species are described: Currhaeus striatus sp. nov., C. nigroapicalis sp. nov., C. championi sp. nov., C. tabascensis sp. nov., C. ruschii sp. nov., C. polegattoi sp. nov., and C. paranaensis sp. nov. Illustrations of diagnostic characters and a key to species identification are presented. Parsimony and maximum likelihood analyses of morphological data demonstrated that Currhaeus gen. nov. belongs in the crown Eurrhacini. Implied weighting parsimony trees recovered Currhaeus as sister to Eurrhacus Waterhouse.

The new genus Afroestricus (Diptera: Asilidae) with 20 species, is described. Included are: A. abyssinia sp. n.; A. chiastoneurus (Speiser), A. eminentis, sp. n.; A. fulaui, sp. n.; A. hamulus, sp. n.; A. insectaris, sp. n.; A. kimerus, sp. n.; A. macroscelis (Bezzi), A. minutus (Bromley), A. morani, sp. n.; A. persuasus (Oldroyd), A. sadaukii, sp. n.; A. sankofa, sp. n.; A. variabilis (Engel), A. varipes (Curran), A. velatus, sp. n.; A. verutus, sp. n.; A. victus, sp. n.; A. vittatus (Curran), and A. vorax, sp. n. Afroestricus is distinctive in the following combination of characters: moderately gibbose face; frons with a wide, lateral, stripe of numerous setae; fore femur with a stout preapical, anteroventral bristle; and a prominent epiphallus that conceals the distiphallus dorsally, characters that are not congruent with Ommatius. New combinations include: A. chiastoneurus, A. macroscelis, A. minutus, A. persuasus, A. variabilis, A. varipes, and A. vittatus. New synonymies include: senax Bromley = chiastroneurus Speiser; munroi Bromley and bevisi Bromley = variabilis Engel; and garambensis Oldroyd = varipes Curran. The species are assigned to the macroscelis and minutus species groups based largely upon wing venation. The genus is largely confined to the Afrotropical region, between 17°N and 31°S latitude, with only the range of A. vittatus extending into western Yemen. The species show a relatively high level of sympatry. Descriptions, illustrations, and a key to the species are included. A brief discussion of the distribution and phenology of the species and a provisional key to the current Afrotropical genera and subgenera of Ommatiinae are also provided.

A New Species

The Afrotropical genus Pegylis Erichson, 1847 (Coleoptera: Scarabaeidae: Melolonthinae: Pegylini) was recently treated by Lacroix (2015), who keyed and figured most of the known species and divided the genus into six species groups based on the number of antennomeres, shape of male genitalia and number of teeth on the protibia. Unfortunately, Lacroix (2015) overlooked two earlier papers by Harrison (2014a, 2014b). Harrison (2014a, 2014b) provided a phylogenetic analysis of the tribe, synonymised Hypopholis Erichson, 1847 with Pegylis, and redescribed the three known South African species of Pegylis. Based on these papers, the genus Pegylis currently contains 37 species.

The taxonomy and systematics of the genus Digitonthophagus Balthasar (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) is revised. A detailed study of the male genitalia combined with external morphology suggests that the variability, previously recognized, for D. gazella is hiding a species complex within the Afrotropical region and the Arabian Peninsula. The current study recognizes 16 species; 13 from the Afrotropical region and Arabian Peninsula and three from the eastern portion of the Saharo-Arabian region and the continental Indomalayan region. Species are organized into six species groups based on the results of the morphology-based phylogenetic analysis. The following 12 species are described as new: D. aksumensis Génier new species; D. biflagellatus Génier new species; D. dilatatus Génier new species; D. eucatta Génier new species; D. falciger Génier new species; D. fimator Génier new species; D. namaquensis Génier new species; D. petilus Génier new species; D. sahelicus Moretto new species; D. uks Génier new species; D. ulcerosus Génier new species; and D. viridicollis Génier new species. In order to stabilize nomenclature, lectotypes are designated for Scarabaeus bonasus Fabricius, 1775; Scarabaeus catta Fabricius, 1787, and Onthophagus gazella lusinganus d’Orbigny. A neotype is designated for Scarabaeus dorcas Olivier, 1789 whose status and synonymy need to be altered in order to clarify the status of Scarabaeus gazella auctorum, the widely introduced species with economic importance. A naming scheme is presented for the sclerites of the internal sac. External and male genitalia are illustrated and distribution maps are provided for each species.

World representatives of the genus Arganthomyza Roháček, 2009 (Diptera, Anthomyzidae) are reviewed, keyed and their relationships are discussed on the basis of a phylogenetic analysis of morphological characters. The Nearctic species of Arganthomyza are revised, described and illustrated, and first data about their biology and distribution are given. Five new species, A. carbo sp. n. (Canada, USA), A. acuticuspis sp. n. (USA), A. bivittata sp. n. (Canada, USA), A. duplex sp. n. (Canada, USA) and A. disjuncta sp. n. (Canada, USA) are described and A. socculata (Zetterstedt, 1847) is newly recorded from the Nearctic Region (USA: Alaska). Based on the phylogenetic analysis, four main clades/species groups are recognized within Arganthomyza, represented by the following species: A. barbarista Roháček, 2009 (A. barbarista group); A. setiplanta (Roháček, 1987), A. versitheca Roháček, 2009 and A. carbo sp. n. (A. setiplanta group); A. acuticuspis sp. n., A. bivittata sp. n. and A. duplex sp. n. (A. duplex group); A. disjuncta sp. n. and A. socculata (Zetterstedt) (A. socculata group). Considering the contemporary distribution and relationships of Arganthomyza species, it is hypothesized that the A. barbarista group and A. setiplanta group originated in East Asia while the A. duplex group and the A. socculata group each has its origin in the Nearctic Region.

AbstractA new genus and species from Brazil, oraea brasiliensis, is described and illustrated, and its phylogenetic affinities are discussed. The genus oraea is diagnosed by the V-shaped buccular juncture, the presence of jugal ridge, evaporative area extensive, mesepimeron barely emergent, male protibia and mesofemur spinose, posterior pronotal lobe with four rounded yellowish macula, unspined aedeagus with two vesical lobes and the gonoporal process enlarged distally. The male of Orthaea meloae Dellapé & Montemayor is described, and the male genitalia of O. meloae and O. alveusincola Harrington are also described and illustrated; O. consuta Dallas is recorded for the first time from Belize, O. meloae from Panama, and O. montana Dellapé & Montemayor from Bolivia. A cladistic analysis of the species of Orthaea Dallas is performed. One most parsimonious tree was obtained, with the following topology: (Myodocha serripes ((Heraeus triguttatus, Paisana brachialis) (oraea brasiliensis (O. consuta ((O. procincta, O. montana) (O. alveusincola, O. meloae)))))). Orthaea was recovered as monophyletic supported by seven synapomorphies.
