The genus Chrysops from the Australasian and Oriental
regions is revised. Two new species are described:
Chrysops fuscomarginalis, sp. nov. and
C. srilankensis, sp. nov. The status of two species is
revised: C. terminalis, stat. rev. is resurrected from
questionable synonymy with C. dispar, and
C. cinctus, stat rev. is resurrected from synonymy with
C. signifer. Fifteen Chrysops
names are placed in synonymy for the first time or placed as synonyms of
species with which they were not previously associated:
C. atrinus syn. of C. silvifacies,
syn. nov.; C. australis papuensis syn. of
C. australis, syn. nov.;
C. flavocallus syn. of
C. flavescens, syn. nov.; C. impar
syn. of C. translucens, syn. nov.;
C. indianus thailandensis syn. of
C. indianus, syn. nov.;
C. intercalatus syn. of
C. pettigrewi, syn. nov.;
C. paradesignatus syn. of
C. designatus, syn. nov.;
C. philipi syn. of C. alter, syn.
nov.; C. semicirculus syn. of
C. terminalis, syn. nov.;
C. silvifacies yunnanensis syn. of
C. silvifacies, syn. nov.;
C. stekhoveni syn. of
C. fixissimus, syn. nov.;
C. subchusanensis syn. of
C. chusanensis, syn. nov.;
C. unizona syn. of C. fixissimus,
syn. nov.; C. vietnamensis syn. of
C. flaviscutellus, syn. nov.; and
C. zhamensis syn. of
C. pettigrewi, syn. nov. An alphabetical list of
Chrysops names for the Oriental and Australasian regions
is given, as is a key to species and descriptions and notes for all valid
taxa. A brief discussion of the biology and economic importance is provided as
well as a discussion of the distribution patterns of Oriental and Australasian
Tabanidae and the northern and western limits of the Oriental region, based on
distribution of Tabanidae.
