The euphorine braconid genus Marshiella is quite rare and enigmatic (Shaw and Marsh 2000). Shaw (1985) named this genus for two species previously included the genera Streblocera and Microctonus. Both species share the unusually heart-shaped modified, densely setose basal flagellomeres (as in Fig. 3) and are included in the tribe Townesilitini by Stigenberg et al. (2015) together with Townesilitus, Streblocera and Proclithrophorus, but the placement of the latter is controversial. Very little is known about the species of Marshiella, including their biology and diversity. They are presumed to be koinobiont endoparasitoids of adult Coleoptera; only one species, M. plumicornis (Ruthe) has been reared from a host, the anthicid beetle Notozus monceros L. They probably orient themselves to their hosts using chemical cues (Shaw and Marsh 2000). Their heart-shaped modified basal antenna are apparently modified for grasping the pronotal horn of their aggressive adult host during oviposition. Only nine species of Marshiella are currently known, two of them are from Oriental China (Yu et al. 2016).
euphorine 肿腿蜂属 Marshiella 相当罕见且神秘（Shaw and Marsh 2000）。Shaw（1985）将这个属命名为两个之前包含在 Streblocera 和 Microctonus 属中的物种。这两个物种都具有异常心形的改良、密集多毛的基鞭节（如图 3 所示），并被 Stigenberg 等人（2015）归入 Townesilitini 部落，与 Townesilitus、Streblocera 和 Proclithrophorus 一起，但其后者的位置存在争议。关于 Marshiella 的物种知之甚少，包括它们的生物学和多样性。它们被认为是成年鞘翅目昆虫的共生内寄生蜂；只有一个物种，M. plumicornis（Ruthe）是从宿主，即 anthicid 甲虫 Notozus monceros L 中饲养的。它们可能使用化学线索来定位它们的宿主（Shaw and Marsh 2000）。它们的心形改良的基部触角显然是为了在产卵时抓住它们攻击性成年宿主的前胸角而改良的。目前已知的 Marshiella 物种只有九个，其中两个来自中国东部（Yu 等人，2016）。
