Discussion : Paragodon paragoides is distinct from minutula van 
Doesburg, the only other known species of Paragodon . Besides the 
key characters and abdominal patterns (Figs. 9, 10) f paragoides 
shows the following differences from minutula : 1 ) face produced 
forward in middle (Fig. 1) ; 2) sides of face not parallel, converging 
to oral margin; 3) third antennal segment three times as long as 
first, not equal; 4) an appendix present on second vein (connected 
to third vein on one side) ; 5) with spurs on first and second pos- 
terior cells.
