Eclimus longipalpis Hardy, 1921: 63 . Type-locality: Australia (NSW); holotype, AM. Thevenetimyia longipalpis ( Hardy, 1921) .– Hall, 1969: 43.

Specimens examined. Australia, ACT, 1♂ pupal case, Mt Clear, emg Jan 1981, K. R. Pullen, from Acacia dealbata infested with Bostrychidae + wasp parasite.

Description. Pupal case. Length: 7.3 mm. Head width: 1.0 mm. Thorax width: 1.1 mm. Abdominal width: 1.2 mm, tapering to 0.3 mm at width of anal segment. Coloration. predominantly pale yellow, spines dark brown to black. Head. Armed with 6 pairs of cephalic spines. One anterior antennal processes (aap) present, aap strong with a small anterodorsal spine, aap 3.0× longer than the anterodorsal spine ( Figs 29g, h ), base area of anterodorsal spine with one dorsal long hair, base area of aap with one lateral long hair. Two posterior antennal processes (pap) present, one large anterior pap with two lateral small spines fused in basal area, one small anteroventral pap with ventral lobe ( Figs 29g, h ). One lateral facial spine (lfsp) present, one median facial hair (mfha) present, one frontal spine (fsp) present. Labral sheath (lsh) long, slightly rugose laterally. Proboscidal sheath (prsh) long, as long as lsh, smooth. Maxillary sheath (msh) smooth, extending 0.3 length of prsh. Palpal sheath (pash) smooth, extending 0.6 length of lsh ( Figs 29c, d ). Thorax. Mostly smooth, one small posterior mesothoracic callosity (pmc) present, without other spines or setae. Wing sheath (wsh) and base half of leg sheaths (lesh) smooth, apex half of lesh rugose ( Fig. 29d ). Fore leg sheath (lesh 1) not exceeding apex of wing sheath, mid leg heath (lesh 2) reaching abdominal segment 4, hind leg sheath (lesh 3) reaching abdominal segment 6. Abdomen. Eight abdominal segments visible, segments 8 and 9 fused ( Fig. 29b ). Abdominal tergite 1 with small short spines, with short setae in the middle. Abdominal tergites 1 to 7 with well-developed chitinous rods with posterior apex raised as spines, and with short setae in the middle ( Fig. 29e ). Abdominal pleurae 2 to 7 each with a transverse row of short setae. Sternites 6 and 7 with a transverse row of setae on posterior half. Anal segment rugose, one dorsal rugose plate present ( Fig. 29i ), one ventral small spine present ( Fig. 29j ). Dorsal posterolateral process (dpp) large and slightly incurved, ventral posterolateral process (vpp) vestigial, tuberculate ( Fig. 29j ).
