The Hercostomus plagiatus species group is defined and distinguished from other Hercostomus groups by the following combination of features including: bulging clypeus in both sexes, anterodorsal comb-like row of setae on fore tibia, usually straight and weakly convergent veins R4+5 and M1+2, hypopygium without basiventral epandrial lobes, mostly free hypandrium, relatively poorly developed postgonite, and female terminalia with tergite 8 and sternite 8 fused anterolaterally forming a narrow process. A new species, Hercostomus golanensis sp. nov., is described from the Middle East (Golan Heights), differing from the other species of this group in the long-pubescent arista-like stylus, triangular rather than oval male cercus and epandrial lobe bearing a very long seta at the base of the stem. A key to species of the H. plagiatus group is provided.
斜纹赫氏蝇种组通过以下特征组合来定义并与其他赫氏蝇组相区分，包括：两性额唇基均隆起，前胫节有前背梳状刚毛排，翅脉R4+5和M1+2通常直且微向内汇聚，尾须无基部腹侧上肛叶，阳茎基侧突大多游离，后阳茎相对发育较差，以及雌虫尾端第8背板和第8腹板在前外侧愈合形成一个狭窄的突起。描述了一个新物种，即戈兰赫氏蝇（Hercostomus golanensis sp. nov.），来自中东地区（戈兰高地），它与该组的其他物种不同之处在于具长柔毛的触角状针突、雄性尾铗呈三角形而非椭圆形，以及上肛叶在柄基部有一根很长的刚毛。提供了斜纹赫氏蝇组物种检索表。
