is more than a subspecies of L. texana Cresson. The problem certainly needs 

 more study.

The HOPEI-Grovp 



In the species of this group the mandibles have a small triangular notch, the 

 lower margin of clypeus has a median tooth (though sometimes weak), the pronotum 

 usually bears a distinct premarginal carina, the dorsellum is not distinctly or not 

 completely and weakly carinate at the margin, the hind coxa dorso-posteriorly 

 thin, sharp, sometimes suggesting a broad lobe but never bearing a narrow tooth, 

 the hind femur is externally rather coarsely punctured, the apex of hind tibia 

 produced into a strong spine bearing at apex a rudiment of the outer spur and 

 in female, if the ovipositor is long, the first tergite has a single median groove. 

 The species belonging here are L. hopei Westwood, L. prbpinqua Schletterer, 

 L. leucotelus Walker, L. brasiliensis sp. n., L. santarema Walker, L. pictipyga sp. n., 

 L. klugii Westwood, L. xylocopae Burks and L. anthidioides Westwood. Some of 

 them are rather different in appearance, e.g. leucotelus and propinqua with blackish 

 wings, anthidioides and xylocopae (which may, eventually, form a subgroup; parasites 

 of Xylocopa species) with short broad body, but there is always a link with the 

 other species, in the case of the anthidioides subgroup it is L. klugii which has 

 also rather short body but already much shorter malar space than anthidioides and 

 resembles more pictipyga in some respects. L. anthidioides was separated as 

 genus Exochlaenus by Shipp (18946) but with the other species known nowadays 

 there is no reason for such a separation, even on a subgeneric level, as recognized 

 already by Weld (1922 : 3).
