03C458531D20592EFF04F9CCFC9FF66E.taxon	biology_ecology	Host. The female was mounted together with an ant specimen subsequently identified as Myrmica incompleta (Fig. 5). Presumably the female was collected with M. incompleta and represents a host record as is customary (Fig. 3). The male specimen had a label reading “ M. rufa. nest of ” pinned to it (Fig. 4). It is unclear what species this label is in reference to. It may be a misspelling in reference to the introduced Myrmica rubra, a Palearctic species, which is still limited to parts of the east and west coasts. Presumably, given the specimen and label data available, Myrmecoagria hoebekei is a symbiont of Myrmica ants, with Myrmica incompleta serving as a host species.	en	Eldredge, K.

03C458531D2C592CFF04FBACFA32F485.taxon	discussion	Myrmecopora incorrectly keys out in Newton et al. (2001) and is corrected here. In Newton et al. (2001), Myrmecopora keys out from couplet 2 to 3 due to the presumed presence of a comb of minute denticles at the apex of tergite VIII. However, examining figures provided by Klimaszewski et al. (2018) for Myrmecopora vaga, the only known Nearctic representative, multiple treatments by Assing (1997 a, b, 2001, 2004) and personal correspondence has lead to the conclusion that a comb of minute denticles at the apex of tergite VIII is not present in Myrmecopora and this correction is reflected here (couplet 2 in both Newton et al. [2001] and key presented here).	en	Eldredge, K. Taro (2022): A new myrmecophilous genus of Falagriini from Colorado, USA (Coleoptera: Staphylinidae: Aleocharinae).
