354 PROC. ENT. SOC. WASH., VOL. 69, NO. 4, DECEMBER, 1967 A NEW SPECIES OF OMANIA FROM MICRONESIA ( Hemiptera : Saldidae ) Jon L. Herring and Harold C. Chapman, Entomology Research Division, ARS, U. S. Department of Agriculture^ The following new species is the first member of the genus Omania Horvath from Micronesia. Previously, four species were known: coleoptratra Horvath, 1915 from the Sultanate of Oman and the Sinai Peninsula, marksae Woodward, 1958 from intertidal coral rocks of the Great Barrier Reef of Australia, samoensis Kellen, 1960 from American Samoa and satoi Miyamoto, 1963 from the Tokara Islands south of Kyushu, Japan. The present species was collected at Nauru Island in southeastern Micronesia. All of the members of the genus are extremely small and secretive and have thus far eluded discovery on most of the islands of Oceania. Both Woodward (1958) and Kellen (1960) have given excellent accounts of the life history, habits and adaptations of these saldids to a marine life in the intertidal zone. Drake (1961) has summarized the literature and included a splendid illustration of O. marksae. Key to the Species of Omania Horvath 1. Eyes small, width two-thirds or less the width of the vertex at level of ocelli, length subequal to length of pronotum; vertex with silvery pu-bescence; hemelytra almost unicolorous 2 Eyes large, width four-fifths or more the width of the vertex at level of ocelli, length greater than length of pronotum; vertex with golden pu-bescence; hemelytra with a contrasting pattern of bluish bloom and black .. 4 2. Collum of head distinctly triangular; all antennal segments concolorous light brown; calluses of pronotum flat, poorly delimited; pronotum, scutellum, and hemelytra uniformly bluish gray; legs light brown ._ coleoptrata Horvath Collum of head not triangular, anterior demarcation arcuate; antennal seg-ments HI and IV dark brown or black; calluses of pronotum slightly raised and clearly demarcated; pronotum, scutellum and hemelytra velvety black 3 3. Antennal segment III only one-half as long as IV, apices of segment I and II fuscus, all of III and IV black; posterior lobe of pronotum about twice as long as the anterior collar; hemelytra uniformly dull black _. satoi Miyamoto Antennal segment III approximately two-thirds as long as IV, apex of seg-ment II and all of III and IV brownish black; posterior lobe of the pronotum only slightly longer than anterior collar; hemelytra marked with a bluish bloom along costal margin and near middle of disk ____ marksae Woodward 4. Length of eye almost one and a half times length of pronotmn, its posterior margin extending beyond the posterior margin of the pronotal collar; ^ Washington, D.
