GHILIANELLA ASSASSIN BUGS — MALDONADO-CAPRILES 433 



Overall body length 13.0 mm. 



The short projections of the posterolateral angles of the terga of 

 nanna may pass unnoticed ; otherwise, the characters in the key will 

 easily separate it from rhabdita, galapagensis , mariae, calva, haitiana, 

 and nebulosa — the other known species under or around 13.0 mm. long. 



Type: Holotype, female, Misiones, Argentina, July 1948, Bernardo 

 Irigoyen collector, USNM 63090. 



Ghilianclla obesa, new species 



Figures 67, 81, 93, 126 



Female: Head, antenna, beak, and thorax brown. Abdomen 

 yellowish brown, darker above. Middle and hind femora with two 

 broad yellowish bands on apical half. 



Body and legs with scarce, short, appressed grayish or yellowish 

 pilosity. 



Head not granulose. Fourth antennal segment two and one-half 

 times as long as third. Interantennal spine not developed. 



Thoracic segments not granulate; lengths: 3.1, 3.4, 1.8 mm. 

 Pro thorax on lateral aspect as in figure 81. Claws of foretarsi two, 

 the inner short and appressed to base of outer. First spine at one 

 and one-third times its length from tip of trochanter. Armature of 

 forefemur with inner row consisting of short and long spines alter- 

 nating with longer fine setae. Basal half of forefemur gradually 

 thickened to first spine. 



Abdomen conspicuously widening to apex of third segment, thence 

 parallel sided to before apex of sixth and narrowing to apex of seventh 

 (fig. 93). Apical angles of third to sixth terga projected laterally. 

 Hind margin of second to fifth terga straight, with moderately large 

 median warts. Wart on fourth tergum larger than that on third and 

 fifth, smaller than that on sixth. Hind margin of sixth tergum angu- 

 larly produced caudad, with large caudally produced median elevation, 

 and constituting the widest part of the abdomen. Seventh tergum 

 slightly shorter than sixth medially, notably narrower apically than 

 basally; hind margin medially angularly produced, tuberculate, and 

 longitudinally ridged. Connexivial areas on each tergum with several 

 subsquare depressions. Eighth tergum notably reduced, hind margin 

 produced, small areas of ninth tergum visible on its sides, margins 

 strongly elevated. Ninth tergum slightly over twice as long as eighth, 

 lateral margin with subapical elevation, with a median ridge on apical 

 half (fig. 12G). Hind margins of second to fifth sterna straight; of 

 sixth deeply and broadly concave. Seventh sternum nearly one and 

 one-half times as long as sixth, hind margin slightly produced medianly 

 (fig. 67). Sterna medianly carinate. Stigma unusually separated from 

 lateral margin.
