“…For example, the egg form of G.intestinalis and G.nasalis appears the same in eggs examined from females nearly 70 years apart in age. Eggs of most of the species have been illustrated to some degree by a number of authors (Collinge, 1910;Dinulescu, 1932;Dove, 1918;Grunin, 1969;Hadwen & Cameron, 1918;Hinton, 1981;Paramonow, 1948;Tatchell, 1961;Wells & Knipling, 1938;Zumpt & Paterson, 1953). In general the egg of each species diagrammed has been in close agreement with others of its kind even though the authors may have been separated temporally and geographically.…”

A key to the eggs of the equid stomach bot flies is presented. Scanning electron photomicrographs of eggs are used to illustrate differences among the eight Gasterophilus species: The eggs include profile is the same for a particular species and is used as a key character for egg identification. Colour of eggs is used in some couplets but only as a supplemental character. Absence or presence of striae on the eggs is used as a primary contrasting character to separate G.pecorum from the other seven species. Shape of the striae varies on eggs of the same species, even those dissected from the same specimen, and is therefore deemed an unreliable taxonomic character for further separation of the Gasterophilus species. Eggs of the same species taken from specimens throughout the world appear the same in profile. Two sets of eggs require close inspection for adequate identification: G.inermis and G.nigricornis separated primarily by the shape of the microphylar region; and G.intestinalis and G.ternicinctus separated by the shape of the egg ventrum. All other eggs have very unique and distinctive profiles. Only G.pecorum was found to possess the Type-II egg attachment organ (AD) used for adherence of the egg to plants or flat surfaces. The eggs of the remaining seven species possess a Type-I AD used to attach the eggs to hair shafts. The type of AD and the degree that the Type-I AD is extended posteriorly were used as key characters in the first and second couplet respectively.

“…They have adapted to a larval life in the alimentary tract of Equidae (Zumpt 1965; Grunin 1969; Colwell et al 2006), and their presence can lead to serious injuries or even death of the host (Hall and Wall 1995; Sequeira et al 2001; Colwell et al 2006; Bezdekova et al 2007; Getachew et al 2012). Because of their great veterinary importance, Gasterophilus species have received considerable attention since the early 1800s (Clark 1815; Dove 1918; Patton 1937; Zumpt and Paterson 1953; James 1974; Otranto et al 2005a, b; Colwell et al 2006, 2007; Zhang et al 2016; Liu et al 2016; Huang et al 2017; Li et al 2018). A total of more than 40 species-group names have been proposed for what is here recognized as nine valid species because of extensive intraspecific variation (Zumpt 1965; Grunin 1969; Pont 1980; Soós and Minář 1986; Cogley 1991a), and a series of misidentifications can be ascribed to their similar larval morphology (Colwell et al 2007; Li et al 2018).…”

A taxonomic review of Gasterophilus is presented, with nine valid species, 51 synonyms and misspellings for the genus and the species, updated diagnoses, worldwide distributions, and a summary of biological information for all species. Identification keys for adults and eggs are elaborated, based on a series of new diagnostic features and supported by high resolution photographs for adults. The genus is shown to have its highest species richness in China and South Africa, with seven species recorded, followed by Mongolia, Senegal, and Ukraine, with six species recorded.
