Thevenetimyia lanigera (Cresson, 1919) View in CoL .– Hall, 1969: 40.

Specimens examined. USA, 1♀ pupal case, California, Los Gatos, 31 May 1918, reared, BPBM; 4 pupal cases, California, 1917, BPBM; holotype USA, of the “ Eclimus leechi Hall, 1954 View in CoL ” ♀, pupal case, California, Marin Co., Mill Valley, 1 Jul 1951, H. B. Leech, emerged from Ceanothus thyrsiflorus View in CoL heavily infested by Ptilinus View in CoL (CAS type no. 6347).

Redescription. Pupal case. Length: 8.0– 10.6 mm. Head width: 1.4–1.5 mm. Thorax width: 1.6–2.0 mm. Abdominal width: 1.6–2.0 mm, tapering to 0.4–0.5 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 ( Figs 30g, h View Figure 30 ), 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 lateral small raise from basal area, one small anteroventral pap with ventral lobe ( Figs 30g, h View Figure 30 ). One lateral facial spine (lfsp) present, one median facial hair (mfha) present, one frontal spine (fsp) present. Labral sheath (lsh) short, slightly rugose laterally. Proboscidal sheath (prsh) short, slightly longer than lsh, smooth. Maxillary sheath (msh) smooth, extending 0.8 length of prsh. Palpal sheath (pash) smooth, extending 0.8 length of lsh ( Figs 30c, d View Figure 30 ). Thorax. Mostly smooth, one small and weak 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. 30d View Figure 30 ). 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. 30b View Figure 30 ). Abdominal tergites 1 and 7 with small short spines, with short setae in the middle. Abdominal tergites 1 to 6 with well-developed chitinous rods with posterior apex raised as spines, and with short setae in the middle ( Fig. 30e View Figure 30 ). 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. 30i View Figure 30 ), one ventral small spine present ( Fig. 30j View Figure 30 ). Dorsal posterolateral process (dpp) large and slightly incurved, ventral posterolateral process (vpp) vestigial, tuberculate ( Fig. 30j View Figure 30 ).

Remarks. T. lanigera is similar to T. longipalpis , but differs by having a short lsh and prsh; and a less armed aap and pap. Both are similar to Hull’s drawing of a Thevenetimyia pupa (1973).

The only pupae described from the tribe Eclimini were Thevenetimyia lanigera (Cresson, 1919) ( Hall, 1954) and Lepidophora culiciformis Walker (Lamas & Lopes, 2004) . The pupae of Lepidophora is similar to Thevenetimyia , but differs as follows: mfha located further from middle; spines on dorsal of abdominal segment 8+9 stronger; aap and pap shorter; legs short. The characters shared by Lepidophora and Thevenetimyia are: hairs short; dpp small and blunt; vpp vestigial; pap small. Bombyliidae pupae do exhibit considerable variation and future, more extensive, comparative studies will reveal the taxonomic and phylogenetic utility of pupal characters.
