Leucospis affinis dubiosa Cresson 

 (Text-figs 62, 63) 



Leucospis dubiosa Cresson, 1872 : 34, $• Holotype $, Mexico (ANS, Philadelphia) [examined]. 



Cresson (1872) noted that L. dubiosa 'may prove to be only a variety of azteca'' 

 and Schletterer (1890 : 282) synonymized dtibiosa with azteca, but I find them 

 different in the shape of the first tergite in the female. Weld (1922 : 10, 27) places 

 dubiosa as a good species without any comment, but in the key she separates it 

 from L. azteca on the less extensively yellow gastral apex and hind femur, apart 

 from smaller size and the hardly shorter ovipositor. In the shape of the ovipositorial 

 furrow on the first tergite (in female), which in my experience does not seem to 

 vary much, I find dubiosa very similar to L. affinis and cannot separate them 

 except on the denser puncturation of the hind leg and the reduced pattern on the 

 pronotum. The female from Alamos shows a short anterior yellow cross-macula 

 on pronotum, the holotype female of dubiosa has it only indicated, the other female 

 lacks it completely as well as all the males. In the Salvador male the pale pattern 

 is much reduced (body size only 5-2 mm), with apical third of gaster black, but 

 the two Alamos males (7-5-8-0 mm) have the fifth tergite posteriorly broadly 

 bordered with yellow, the sixth tergite extensively yellow and even the epipygium 

 partly yellow. Such a pattern might correspond, in the female, with something 

 as described for L. azteca. The Mitla male is intermediate between the two extremes. 

 To conclude, I assume that the shape of the first tergite excludes azteca as a different 

 species, while dubiosa is a subspecies of L. affinis Say.
