On Lanai, this species has been collected only once near Lanaihale ( Fig. 5D ). It is recorded from all of the other Hawaiian high islands ( Liebherr 2008 a ). The specimen is brachypterous, suggesting long-term persistence of a population of this species on the island ( Southwood 1977 ). Habitat. The single Lanai specimen was collected during daytime by beating foliage of a small ohia tree situated in open forest with uluhe fern understory. The ohia had a thin covering of lichens and some moss clumps. Cibotium Kaulfuss tree ferns and other ohia trees were beaten in the vicinity, producing specimens of B. depressa and M. filipes . Tribe Platynini Diagnosis. Diagnosable within the Hawaiian fauna by: 1) conjunct mesocoxal cavities; 2) glabrous mandibular scrobe; 3) mesally glabrous pronotal disc and third visible abdominal ventrite; and 4) lateral elytral margins bearing only lateral elytral setae situated in depressed foveae, without a pelage of fine microsetae covering the areas between the lateral setae (Liebherr and Zimmerman 2000). The five species of Blackburnia plus the non-native platynine species M. buchanani that are recorded from Lanai are taxonomically treated by Liebherr and Zimmerman (2000).
