Paramere 0.6 times as long as proctiger, subrectangular; in lateral view, 1.8 times as long as broad; with short digitiform antero-apical strongly sclerotized process which is directed in oblique dorsal direction, and broad postero-apical strongly sclerotized tooth; antero-apical edge weakly curved; covered in long setae in distal and posterior half on the outer face, and more or less evenly on the entire inner face.

Eyes separated by 1.0 (male) or 1.5-2.0 (female) facet diameters; antenna with 14 flagellomeres, the 3 apical subequal are reduced in size, 11th and 12th fused, 14th separated and spherical; ascoids Y-shaped; wing with medial fork incomplete; female subgenital plate pilose on distal half and with lateral margins convex; male terminalia with gonostyle coniform with a group of alveoli at base and short setae sparsealy distributed, aedeagus asymmetrical, bifid with left branch little longer and wider in dorsal view, one short sinuous paramere articulat with aedeagus and a small projection of the hypandrium, gonocoxal apodeme strongly sclerotized, pilose ventrally and with rounded distal margin.
Other than these characters, genus Halys is totally different from Neohalys in having comparatively short labium, striking difference is in the shape of paramere, both stem and blade and most peculiar is the apex of paramere blade and to some extent shape of pygophore too; the male genitalia of Salixocoris is also very different from genus Halys, particularly the venteroposterior margin of pygophore, and shape of conjunctival appendages.
Etymology: From Latin verruca (wart), referring to the rugose field on the paramere. Diagnostic characters: As for genus.
The anterior process of the left paramere is heavily sclerotized, an attribute that we have emphasized in figure 1.
celiae usually has 7 setae, a few thin hair, and the paramere is sickle shaped dorsally.
A comparison was made of the general structure of the terminal end of the aedeagus, especially in regard to paramere structure.

boutropis it differs by having syntergosternite 8 not being divided by a membranous area; from panamaensis it differs by the following: scutellum with two black bristles at the margin, hind tibia without erect posterior bristles medially and paramere with a subapical lateral projection.
