Adult histaminergic neuron with its cell body in the metathoracic neuromere (Nassel et al., 1990). There are one or two of these cells on each side and their somas are located ventrally and posteriorly, near the border with the abdominal neuromere (Nassel et al., 1990; Cheong et al., 2024). It has an axon that runs dorsally and anteriorly, entering the cervical connective (Nassel et al., 1990; Cheong et al., 2024). Its arbors are mainly found in the contralateral central nervous system (Cheong et al., 2024). Its input is mainly from the intermediate tectulum of the meso- and meta-thoracic neuromeres and it outputs to all three contralateral leg neuropils, the dorsal gnathal ganglion and the antennal mechanosensory and motor center (Cheong et al., 2024).

Nassel et al. (1990) say two of these on each side, but Cheong et al. (2023) only find one per side (both by IHC).
