Type host: Otidiphaps nobilis Gould. Description Male head broadly bell–shaped ( Figure 102 ); APW , 0.216; HW , 0.40–0.42 (0.410); HL, 0.56–0.58 (0.570); HL/ HW , 1.38–1.40 (1.39); SL, 0.170 –0.176 (0.173). Thorax with PW , 0.35–0.36 (0.357); MW , 0.42–0.43 (0.427). Genitalia ( Figure 104 ) with parameres ribbon-like, wrapping behind mesosome; GW, 0.123 –0.137 (0.131). TL, 2.20–2.25 (2.23). Female similar to male except as follows. Head as in Figure 103 ; dorsal head setae shorter; APW , 0.220 –0.245 (0.230); HW , 0.42–0.45 (0.431); HL, 0.61–0.65 (0.626); HL/ HW , 1.40–1.48 (1.45). Thorax with PW , 0.35–0.37 (0.360); MW , 0.44–0.47 (0.448). Ventral terminalia as in Figure 105 ; subgenital plate slightly expanded anteriorly. TL, 2.40– 2.55 (2.48) . Material 3 males , 8 females , ex O. nobilis , Papua New Guinea (4). Remarks Tendeiro (1965) was unable to study this species directly because the type specimens were deposited in the collection of the University of Halle and were almost certainly destroyed in World War II. The species was later redescribed and illustrated by Emerson and Price (1979) ; it is easily recognized by the structure of the head and genitalia.
