Body length of adults vary from 2.0 mm to 3.0 mm depending on the response to the preservative before death. The dorsal jaw base varies from crescent-shaped to elongate oval, while the ventral jaw base is oval to banana-shaped. Measuring the width of the jaws was found to be less influenced by aspect than other jaw dimensions, e.g., height of the median tooth. The dorsal jaw widths ranged from 41.0 μm to 52.0 μm (N = 22, mean value 44.6 μm) and for the ventral jaw, 28.9 μm to 46.0 μm (N = 18, mean value 34.9 μm).
