REMARKS. Leucospis histrio has large variations in the body size (from 6 to 8. 6 mm long) ( Fig. 18 ) and yellow markings. For the latter, variations are as follows: in small specimens, the supraclypeal area without a yellow spot ( Fig. 15 ) (in large specimens the supraclypeal area with a yellow spot ( Fig. 8 )), the mesoscutum with a pair of very small yellow spots medially ( Fig. 16 ) (in large specimens the mesoscutum with a pair of very large yellow spots medially ( Fig. 10 )), and the ventral surface of fore femur with a very short yellow band ( Fig. 17 ) (in large specimens, the ventral surface of fore femur with a long yellow band ( Fig. 14 )).
