Nicaragua and Panama.

Remarks

Mycotretus interstitialis Kuhnt, 1910 is almost identical to M. interstictus Gorham 1888 , the single detectable difference being that a black cephalic spot is apparently absent on the former and present on M. interstictus . Based on general similarities and the proximity of their type localities ( Nicaragua and Panama), we synonymize M. interstitialis under M. interstictus .
