title: Peripheral nervous system of the larva and adult of Sarcophaga ruficornis Fabr. (Diptera: Sarcophagidae).
abstract: In larva the thoracic and abdominal ganglia of ventral nerve cord are amalgamated into a thoracoabdominal ganglionic "mass". 3 thoracic and 8 paired lateral segmental nerves arise from the "mass" and innervate 1st to 8th abdominal segments. Besides these, 7 mid dorsal nerves arise and bifurcate into left and right branches. These innervate the musculature of the 2nd to 8th abdominal segments. The suboesophageal ganglion is incorporated in the brain. In adult, the cervical connective separates the brain from the "mass" and gives a paired cervical nerve. Optic nerves are absent whereas antennary nerves are stout and prominent. 2 paired nerves arise from the brain. 15 paired and an unpaired nerves arise from the prothoracic (6), mesothoracic (4), metathoracic (4) and abdominal (1 + 1 unpaired) neuromeres of the "mass". Origin, distribution and destination of these nerves are described in detail.
