Diagnosis. Myiomma taxa can be recognized by the following characters: Body length 1.8–3.2, elongate oval; body coloration usually pale brown to blackish brown, often male and female possesses different coloration; dorsum weakly shining, usually covered with pale to dark brown simple setae; compound eyes large, sometimes adjacent to each other; vertex narrow, with a pair of distinct, round ocelli; antennal segment I short and stout, segment II thick, elongated and weakly clavate in male, segment III and IV short and thin; pronotum trapezoidal, anterior margin linear, posterior margin somewhat round, W-shaped; mesoscutum distinct, laterally wide; foreleg and midleg thin and linear, hindleg with thickened metafemur; male endosoma membranous, weakly sclerotized; left paramere with moderately swollen sensory lobe and elongated, apically tapering hypophysis; right paramere small, horn-shaped; female genitalia with weakly sclerotized rings and interramal structures. For more diagnostic characters and figures, see Yasunaga et al. (2017) and Liu et al. (2022).

Distribution. Afrotropical, Australasia, Nearctic, Neotropical, Oriental, and Palearctic region ( Schuh, 2002 – 2013; Yasunaga et al., 2017)

Biology. Members of genus Myiomma can be found on tree bark of diverse types of deciduous trees ( Yasunaga & Hayashi, 2002). This group can be collected with various insect trap, such as funnel traps, light traps, and malaise traps ( Henry & Carpintero, 2012; Yasunaga et al., 2017). Based on observational data, species of Myiomma are presumed to be predaceous ( Wheeler & Henry, 1978; Henry & Carpintero, 2012; Shishido et al., 2020; Yeshwanth et al., 2021).
