Elongated hind metatars would support varipes, as would the date. |

In America some of the common species of Bibio have several synonyms due to variation in leg color. |

Yes, this “atripes” variation is confusing, hence the doubled key-out. Note that all intermediates do occur. ( meaning: the question whether or not this is atripes, is ill-defined) Theo |
