| The implications of this observation and others are discussed with regard to the evolution of myrmecophily in T. virgilius. |
| She is also studying the evolution of myrmecophily within one of these lineages. |
| We note that the myrmecophily of the two species has the same adaptive rationale. |
| To understand the patterns of associations in the field we therefore need to measure the benefits and costs of myrmecophily both in the presence and in the absence of ants. |
| A key to myrmecophilous taxa is presented, and the status of their myrmecophily is briefly discussed. |
