Summary:

While the genus Geocoris has not invaded insular areas to any great extent, it has been found in the Philippine Islands and on all mainland areas surrounding the Pacific. In addition, members of the subfamily Geocorinae have long been known from islands of Oceania where, in the Marquesas Islands, exploration has shown that no less than seven species of Germalus have been discovered there. However, the first Hawaiian record of any member of the Geocorinae was in 1936 when a specimen of Geocoris punctipes was collected on Cynodon dactylon at Pearl City, Oahu, in 1935 and subsequent collections indicate that the genus is firmly established in Hawaii. The author goes on to describe the characteristics and the areas of which the Genus geocoris fallen, Geocoris grylloides, Geocoris punctipes, and the Geocoris pallens were found in various locations in Hawaii such as at Barking Sands on the island of Kauai, at Ewa Coral Plain and in Pearl City on the island of Oahu, and at Humuula and Lake Waiau, on the island of Hawaii. The status as to whether or not this species is beneficial or harmful has not yet been determined as the evidence concerning the biology of the entire group was not conclusive. However, at the writing of this paper, it was felt that the genus Germalus should be considered predacious.
