The [[Nematocera]]n family '''Axymyiidae''' is the sole member of the infraorder '''Axymyiomorpha''', though it is often included within the infraorder [[Bibionomorpha]] in older classifications. It is known from only six species in three genera, plus three fossil species.

The head is rounded. The eyes of the male are [[holoptic]] for a considerable distance and divided into a larger dorsal part consisting of large facets and (separated by a groove) a smaller ventral part of smaller facets. The eyes of the female are separated by a broad frons and consist of separated facets. The three ocelli are on a prominence. The antennae are short with 14 to 16 transverse segments which are covered with sparse, short hairs. The oral parts are reduced. The palpi are four- to five-segmented.

The Nematoceran family Axymyiidae is the sole member of the infraorder Axymyiomorpha, though it is often included within the infraorder Bibionomorpha in older classifications. It is known from only nine species in four genera, plus eight fossil species.

Family characteristics

[edit]

The Axymyiidae have the general appearance of the Bibionidae. Unlike bibionids, axymyiids have four branches of the radial vein, Bibionidae have two or three.

The head is rounded. The eyes of the male are holoptic for a considerable distance and divided into a larger dorsal part consisting of large facets and (separated by a groove) a smaller ventral part of smaller facets. The eyes of the female are separated by a broad frons and consist of separated facets. The three ocelli are on a prominence. The antennae are short with 14 to 16 transverse segments which are covered with sparse, short hairs. The oral parts are reduced. The palpi are four- to five-segmented.

Wings have an ocellus. Wing-venation: The subcostal vein merges into the anterior alar margin near its midpoint; radial vein 1 reaches the distal quarter of wings, there usually fused with radial vein 2+3; radial vein 4 is branched proximal to the anterior crossvein of the wing. Median vein 1 and 2 have short trunks. The anal vein does not reach the alar margin.

The tibiae are slightly longer than the femora, but somewhat shorter than the tarsi. The empodium and pulvilli are well developed.

Biology

[edit]

Larvae live in decomposing wood.

Genera

[edit]

The family contains four extant genera and four extinct genera:[1][2][3][4][5]
