About Trichorhina tomentosa
Trichorhina tomentosa is a minute, pale terrestrial isopod in Platyarthridae. Taiti and Howarth (1996, p. 63) report six female specimens from Acacia decurrens humus along Highway 55 near Waimea, 5.7 miles (9.2 km) beyond its junction with Highway 50, on 14 May 1969. Their account describes parthenogenesis, a wide ecological range, and broad tropical distribution; the island checklist classifies it as adventive. The documented substrate is the collection microhabitat, and should not be generalized into an exclusive host association. Small off-white, oval animals with short club-shaped dorsal spines and a single tiny ommatidium accord with independent identification descriptions, although microscopic characters are not established anew by the historical Kauaʻi record. The six 1969 females establish historical occurrence, not current persistence, reproductive rate, or island-wide abundance; no contemporary local status is asserted.
