Material examined. TWENTY-TWO FEMALES, 9 MALES, RAISED FROM FEMALES cOLLEcTED ON Auricularia polytricha, WUFENG, TAIcHUNG, TAIWAN, 19.XI.2016, H. SHENTU.

Remarks. IN THE ORIGINAL DEScRIPTION, RAcK (1983) ILLUSTRATED SMALL SOLENIDIA ON TIBIAE II AND III IN FEMALE. IN FAcT, SOLENIDIA ON TIBIAE III AND IV ARE ABSENT ( FIG. 9D View FIGURE 9 ), BUT THERE ARE SUBcUTIcULAR INVAGINATIONS ON THE TYPIcAL LOcALITY OF TIBIAL SOLENIDIA. THESE INVAGINATIONS ARE VERY SIMILAR TO TINY SOLENIDIA ( FIG. 7 View FIGURE 7 ) AND RAcK (1983) ERRONEOUSLY INTERPRETED THESE STRUcTURES AS SOLENIDIA. ALSO, IN THE ORIGINAL DEScRIPTION OF THE MALE ( RAcK 1983) SETA d ON TIBIA IV IS ABSENT. IN FAcT, THIS SETA IS PRESENT, BUT VERY SMALL AND TYPIcALLY HIDES UNDER THE LARGE TIBIAL SOLENIDION.
