GHILIANELLA ASSASSIN BUGS — MALDONADO-CAPRILES 425 



Overall body length 22.0 mm. 



G. globifera is the only species having the fourth tergum the widest 

 part of the bulbosity. The genitalia of the other three females at 

 hand show slight variations from the hypotype. In one the eighth 

 tergum is nearly semicircular, but the details of its surface agree with 

 those of the hypotype. In another the ninth tergum is relatively 

 shorter and broader but otherwise is similar. In the third the ninth 

 tergum has a small notch on either side before apex. The hypotype 

 was collected in coitu with a specimen that agrees closely with McAtee 

 and Malloch's description. 



Types: Hypotype, female, Villavicencio, M.I., Colombia, July 23, 

 1938, H. S. Dybas collector, CNHM. Parahypotypes, three females: 

 one collected by H. S. Dybas, July 13, 1938, CNHM; one collected 

 by C. H. Seevers, author's collection; and one collected January 20, 

 1948, PW; all three from Cano Grande, Colombia. Six males of this 

 species have been identified, one of them, as mentioned above, was 

 collected in coitu with the female hypotype.

Figures 17, 34, 63, 101, 102, 141 



Male: Head, thorax, and legs brown. Abdomen blackish brown. 



Body covered with sparse decumbent yellowish hairs. Abdomen 

 with 14 patches of yellowish white hairs as follows: 2 small patches on 

 hind margin of fourth and fifth terga, 4 near hind margin of fourth 

 sternum, 2 more extensive near anterior margin of fifth sternum, and 

 4 near posterior margin of fifth sternum. 



Head conspicuously granulose, eyes moderately small. Long 

 straight interantennal spine. 



Thoracic segments conspicuously granulose; lengths of segments: 

 2.5, 3.5, 2.2 mm. Armature of forefemur with inner row consisting of 

 alternate long and short spines and between them longer fine setae 

 arising from wartlike bases. Claws of foretarsi two, the inner one 

 shorter and appressed to base of first. First spine of forefemur at 

 slightly less than three and one-half times its length from tip of 

 trochanter. Basal half of forefemur gradually thickened to first spine. 



Abdomen with bulbous swelling. Apical angles of second to fourth 

 terga not produced. Abdomen gradually widened to apical throe- 

 fourths of fourth segment. Apical fourth of fourth segment forming 

 minor part of bulbosity, its hind margin conspicuously convex. Fifth 

 segment constituting major and widest part of bulbosity, the margins 

 of the tergum produced over lateral margins of segment, the margins 

 pointed on apical two-thirds (fig. 102). Basal third of sixth segment 

 forming minor part of bulbosity. Seventh tergum as in figure 34, 

 narrowed portion from basal third to apical two-thirds, apical third
