Tiphia layoiiae, new species 



Tiphia layouae differs from T. dominica in having a distinctly wider 

 cheek and a well-defined transverse carina, complete across the dorsum 

 of the first tergum. 



Male. — Differs from the description of the male of T. dominica as 

 follows: The secondary punctures of the front are usually confined to 

 a smaller area. The cheek is wider and almost as wide as the antennal 

 fossa. The head width is 2.25 times the least distance between the 

 eyes (four measured were 2.3, 2.3, 2.2, 2.2). The discal punctures of 

 the mesopleuron average slightly coarser. The sections of the second 

 cubital cell defined in ratios of the first intercubital vein and listed 

 clockwise (average of 4) are 1.0, 2.44, 1.76, 1.89 and are almost 

 identical with the cubital cell ratios of T. dominica. Tergum 1 with 

 a well-defined transverse carina extending entirely across dorsum. 



Length 5 to 8 mm. 



Female. — Unknown.
