Suture with a narrow band of granules along margin. Abdomen (Fig. 4b). Tergites II—VI with a pair of dark brown point patches anteriorly, twice as broad as long on tergite II, progressively reduced and more circular on following segments; point patches small, little more than length of tergite on IV. Tergites III—V covered with minute shagreen points arranged in more or less transverse rows, less extensive on II; on VI and VII this fine armament is progressively reduced posteriorly; tergite VIII with antero-lateral shagreen patches only. 70-89 hooks in hook row of tergite II.

Greenish-pink in life, smudged brownish posteriorly. Head brown, mentum and apices of mandibles dark brown. Antenna (Fig. 5e), segments 80, 23, , 5, 5 /*m long; AR Antennal seta on first segment at from base; ring organ at base of first segment; blade about as long as second segment, accessory blade about half as long as blade. Lauterborn organs on segment 2 reaching tip of antenna. Mentum (Fig. 5d) with anterior outline weakly convex: teeth generally very worn (Fig. 5a); median tooth simple, weakly shouldered laterally; the inner four of the five lateral pairs of teeth about equal in size, the outermost much smaller. Ventromental plates (Fig. 5d) about six times as. Please note that these images are
