[ Labrador is a shorthand for Labrador Park , a nature reserve in SW Singapore ]; (all in RMNH ) . Diagnosis: Body length of male (1.15–1.44), female (1.48–1.59). It can be distinguished from other species of Corallocoris by the following characteristics: the body is nearly black, the forewing has a distinct grey transverse fascia and grey apical margin ( Fig. 7A–B, F ). Habitat and biology. Corallocoris marksae was collected by searching volcanic rocks lying in the intertidal zone of a shallow, protected lagoon, which exposed 25 feet of beach at low tide and was covered by up to 2 feet of water at high tide ( Kellen 1960 ). The motor behaviors of this species in the field were recorded by Kellen (1960) and he reared entire generations in the laboratory. Woodward (1958) recorded finding C. marksae mainly on the moist undersurface of the slabs of porous coral rock and on the sand and rock beneath when these rocks were exposed, together with Collembola, mites ( Microtrombidium sp. and Eupodes sp. ) and small beetles. Distribution: Australia (Great Barrier Reef); Malaysia (Malaya); New Caledonia (Îlot Croissant); Philippines (Badian, Luzon); Samoa (Tutuila Island); and Singapore (Sentosa Island) ( Fig. 9A , Table 3 ).
