Bicaubittacus sonani

Bicaubittacus sonani  (Issiki, 1929)

The very small male epiandrial lobes places this species in Bicaubittacus.  The epiandrial lobes are about the same length as the cerci and about ½ the length of the basistyles.  Other distinctive characteristics include a dentate base of the aedeagus and small denticles at the apicodorsal margin of the epiandrial lobes.

Distribution – Geographical
:  This species is endemic to Taiwan.  Within the island it is known only from Sungkang (= Mt. Tattaka).

Distribution – Temporal
:  The only known specimen was collected on 3 June 1927 at 2133 m (7000 ft.) by J. Sonan.

:  This specimen was collected at what seems like extraordinarily high elevation.

:  Nothing is known of its life history or immature stages.

Notes:  This species is named for Jinhaku Sonan who collected many of the Mecoptera specimens used in Dr. Issiki’s descriptions.  More about his life can be found at
