Zavrelimyia hirtimana

Author: (Kieffer, 1918)

Exuviae 6.1-7.0mm long (m=6.6mm, n=10).
Cephalothorax: Thoracic horn 400-450µm long (m=419µm, n=11), curved shortly after the base, more or less parallel-sided or widened towards apex, toothed; ThR 3.3-4.83 (m=4.3, n=11). Plastron plate offset at horn apex, with a clear rim; plate 25-30x13-25µm (n=10); maximum diameter 0.06-0.07x horn length, 1.9-3.8x width neck, 0.28-0.35x maximum width rim (n=12). Respiratory atrium thin-walled, 0.41-0.61x lumen width (n=12), at most a little undulate marginally.
Abdomen: Tergite VIII with shagreen restricted to a posterior median transverse patch, with, or without, a similar anterior patch (N.B. the sternite is nearly covered with spinules except for a median posterior bare area). Pleura of tergites III-V spinulated only for posterior two-thirds to three-quarters. Anterior lateral taenia of segment VII at 0.40-0.45 of length segment VII (n=8). Anterior lateral taenia of segment VIII at 0.26-0.33 of length segment VIII (n=8).
Anal segment: Anal lobes toothed strongly both externally beyond the lateral taeniae and internally, both margins convexly narrowed to apex. Anal lobe ratio 2.64-3.25 (n=8). Insertion of anterior anal taenia at 0.37-0.43 of lobe length (n=8).
