Brevivulva is an

Early Eocene[2] Baltic amber deposits in the Baltic Sea region of Europe.[1]

History and classification

Brevivulva electroma is known only from one fossil, the holotype, number "AMNH BaJWJ-408", which is a single female specimen preserved near the end of a triangular amber block 21 by 5 millimetres (0.83 by 0.20 in) in size. The block is currently residing in the

paleoentomology collections in New York City.[1] B. electroma was first studied by Gary A.P. Gibson, with his 2009 type description being published in the journal ZooKeys.[1] The generic name combines the Latin words brevis, meaning "short", and vulva, meaning "cover" or "wrapper" and refers to the short length of the hypopygium in comparison to the modern genus Lambdobregma. The specific epithet "electroma" derives from the Latin electrum "amber".[1]

Description

Brevivulva electroma is 3.25 millimetres (0.128 in) in length when the

setose along the front edge of the wing margin in the costal cell. Beyond the parastigma the setae grow sparse and the wing apex is apparently bare.[1]

The overall structure of and general appearance is very similar to that of living species in the genus Lambdobregma. This includes Brevivulva having a

parasitic on woodboring beetles or other hosts with similar habits of concealment.[1]
