dc.description.abstract "Species of the large neotropical and Indopacific genus Zygothrica are reclassified from Burla's (1956) species-groups, as based on cladistic character analyses and a classification reflecting relative genealogical relationships. The genus is defined by a prominent and sharp facial carina, a medially cleft oral margin, and a sclerotized proboscis with an acute joint between the mentum and submentum. Zygothrica is divided into five sections, and each section is variously divided into hierarchical levels. Cladistic hypotheses are based on adult morphological traits and reproductive behavioral repertoires of seven of the species. Breeding records are reviewed and immatures of three species are described. Removed from Zygothrica and placed into the thoracis species-group of Drosophila (Hirtodrosophilia) are the following: D.(H.) clypitata, n. nov. (for Z. clypeata Burla, 1956), D.(H.) strigocula, n. comb., and D.(H.) pleurostrigata, n.comb. Species accounts are given for 62 (neotropical) members of clade 1, which is a portion of the largest Zygotrica group. Of these, 48 are new species described as the following: abbrevidispar, aliucapa, amplialdrichi, andea, antedispar, anota, bilinefilia, caputrichia, celsa, centralis, cryptica, dissimulata, femina, florinjecta, fuscalata, glossusta, joeyesco, karenae, latipanops, latipaps, manni, mediogaster, mediovitta, microeristes, neolinea, nigra, nigropleura, ora, oviserrata, pallida, panamensis, panopia, paravitta, perplexa, peruviana, pictura, posthona, prensiseta, radialis, simulans, somatia, sphaerocera, spinathigma, tambopata, trinidada, vitrea, zonata, and zygia. Provided for most of the 62 species are distribution maps and figures of various diagnostic morphological features, including wings and male and female terminalia. Synonymies are given for Zygothrica orbitalis (Sturt.) (which are Z. nitidifrons Duda, Z. ochracella Hendel, and Z. parilis Burla) and Z. bilineata (Williston) (synonym: Z. gemma Burla). Zygothrica poeyi of Burla is a misidentification for Z. laevifrons Duda. Hypotheses of supraspecific relationships within a large portion of clade 1 are discussed. Fourteen species have broad-headed ('hypercephalic') males, and the trait is hypothesized to have arisen six times among them"--P. 107. en_US

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
