FUR -- Linear measure between dorsocaudal tip and ventral edge of apophysis furculae.
Furculae represented by two small, digitiform, thin projections slightly longer than broad, with rounded tip.
Measurement data were obtained for tegmen length (from lowest insertion along lower pronotum to tip), narrowest dorsal distance between eyes, and length of male furculae. Measurements of tegmen length were done using a vernier caliper and estimated to the nearest 0.1 mm, while measurements of the intereye distance and length of furculae were taken with an optical micrometer (Scope: Clympus SZ-STS, 2.5x x 10x = 25x; Micrometer: Clympus AX0001 CB-M, 1/100 mm).
Furculae distinct, raised comma-shaped protuberances, extending about one fourth length of the supra-anal plate.
