obsolete large basiconic sensillum [FBbt_00005188]

The largest subtype of basiconic sensilla. It measures 12 micrometers and 2.5 micrometers wide with blunt tips. Directly above the base of the sensillum, the shaft diameter is often somewhat reduced resulting in a club-shaped appearance. The pores are arranged in lines, positioned wider apart than in the small basiconic sensillum. It is innervated by two or 4 sensory neurons. Two subtypes can be identified, base on the internal morphology of the peg (LB-I and LB-II). Large basiconic sensilla are found in the antennal segment 3.
