CYDNIDAE OF THE WESTERN HEMISPHERE — FROESCHNER 393 



Type of subgenus. — Findalia lucida Jensen-Haarup (1926, p. 52), 

 monobasic. The locality given with the original description was 

 "Brazil," but the type specimen bears no locality label. 



Discussion. — Except for the development of the peritreme (a 

 structure which I beheve to be a prime phylogenetic indicator), the 

 single species of the subgenus is well removed from the other species 

 of the genus. 



RhytidopoTus (Findalia) lucida (Jensen-Haarup), new combination 

 Plate figure 94 

 Findalia lucida Jensen-Haarup, 1926, p. 52. 



Diagnosis. — Since this is the only species known for this subgenus 

 the subgeneric characters will place it within the genus. 



Description. — Known only from the type female. Female: 

 Elongate-oval, nearly parallel-sided but slightly wider behind mid- 

 length. 



Head: Length about two-thirds width, 0.56:0.88; interocular 

 width, 0.53; anterior outline semich-cular, clypeus as long as juga, 

 but slightly narrowed at apex; surface alutaceous, with scattered 

 minute punctures; jugum with two submarginal setigerous punctures, 

 one prcocular and one near middle; ocelli moderately large, separated 

 from eye by space subequal to transverse diameter of ocellus; jugum 

 ventraily and maxillary plate polished, unpunctate. Antennal 

 segments: I, 0.20; II-V missing; bucculae nearly as high as labial 

 II. Labial segments (III, IV, missing) : I, 0.30:11, 0.53. 



Pronotum: Length less than half width, 0.94:2.00; anterior margin 

 deeply, doubly emarginate; lateral margin entire, more strongly 

 curved on apical half, with submarginal row of four setigerous 

 punctures; transverse impression absent, marked by one or two distinct 

 punctures at extreme ends; surface, except for a few fine punctures 

 near anterior margin and some scattered laterally, virtually impunctate. 



Hemelytron: Clavus and corium finely alutaceous; clavus with one 

 longitudinal row of punctures; mesocoriun with two complete rows 

 of punctures paralleling claval suture, discally with a few distinct 

 punctures that become more numerous apically; exocorium weakly 

 convex, with numerous obsolete punctures for full length; costa very 

 fine, with one small setegerous puncture subbasally; membranal 

 suture slightly concave; membrane surpassing apex of abdomen, 

 slightly longer than basal width. 



Propleuron: Shining, obsoletely alutaceous, impunctate; prosternal 

 carinae sharp, less than half as high as labial II. 



Mesopleuron: Evaporatorium filling all but narrow anterior, 

 posterior, and extreme lateral margins of segments.
