Leucospis xylocopae Burks 



Leucospis xylocopae Burks, 1961 : 537-540, figs 1-4, °- $. Holotype $, Brazil: Sao Paulo 

 State, Usina Esther nr Cosmopolis (USNM). 



Dr Burks kindly sent me paratypes for examination. L. xylocopae is very close 

 to L. anthidioides Westwood and very similar, except that the yellow markings 

 are less extensive and usually also the ovipositor is shorter. In the specimens 

 examined the first tergite is always without yellow markings, its puncturation is 

 slightly finer, pilosity more erect and thinner than in anthidioides. The second 

 tergite is medially slightly produced. The apical processus of the stigmal vein in 

 the fore wing usually less distinct than in anthidioides. Compare also notes on the 

 sternites in the male under anthidioides. 



Biology. Reared from Xylocopa nogueirai Hurd & Moure, Apidae (Burks, 

 1961). 



Distribution. Brazil, Paraguay. 



Material examined.

The AFFINIS-Groxjp 



The few species belonging here are L. latifrons Schletterer, L. azteca Cresson, 

 L. affinis Say and L. poeyi Guerin-Meneville, mostly confined to North and Central 

 America, only L. latifrons spreading as far south as Bolivia. They are all very 

 similar in appearance, with a relatively slender body and in the females the ovipositor 

 reaching about or beyond the base of the gaster, with relatively weak metallic 

 tint which is more distinct only on the head, mainly in and above the scrobes. 

 The lower tooth of the mandibles is separated by a rather small notch, the lower 

 margin of clypeus has a median tooth (as the hopei-gtoup) . The metanotal 

 dorsellum is coarsely punctured, never distinctly carinate posteriorly. The hind 

 coxa bears dorsally a tooth, the hind femur has many small teeth following the 

 larger basal one (as in all other groups except the texana-group) , the tibia is almost 

 perpendicularly truncate at apex, with the outer spur well developed (difference 

 from the closely related hopei-group and the egaia-group) , the hind coxa never 

 extensively smooth, always bearing dorsally a rather narrow tooth which bears 

 some punctures, but may be less distinct in unusually small specimens.
