T. Andersen (ZMBN) . Paratypes: 5 pharate male pupae, 3 pharate female pupae, 3 pupae exuviae, as holotype (ZMBN); 1 pharate female pupa, CHILE, Región Metropolitana, San José de Maipo, Cajon del Maipo, Lo Valdes, Rio Volcán, 33.856273 oS 69.982294 oW, 2.540 m a.s.l., 10 November 1998, drift net, leg. T . Andersen (ZMBN).</p><p>Etymology: Named after the country of origin.</p><p>Diagnostic characters: The male can easily be separated from the male of M. (B.) floridensis by having bi- to multiserial orbitals and a strong comb on hind tibia; M. (B.) floridensis has uniserial orbitals and lack comb on hind tibia. The pupa possesses the large, spine-like D 1 setae arising from prominent tubercles on tergites II– VII, which is characteristic for M. (B.) floridensis . However, the thoracic horn is somewhat triangular and curved and is more similar to the thoracic horn in some other Macropelopia (s. str.) species than in M. (B.) floridensis .</p><p>Description: Male (pharate male pupae) (n = 5, if not otherwise stated).</p><p>Coloration. Brown.</p><p>Antenna.

Dorsocentrals irregularly biserial; acrostichals tri- to multiserial; scutellum with transverse row of 15–22, 18 strong setae and 7–13, 12 weaker setae anterodorsally; postnotum apparently with altogether about 13 (1) setae, biserial; other setae difficult to observe. Scutal tubercle apparently low, difficult to observe in the slides.</p><p>Wing. Not measurable.</p><p>Legs. Width at apex of fore tibia 73–77 (3) µm; of mid tibia 70–76, 73 µm; of hid tibia 80– 82, 81 µm. Spur of fore tibia 80–86 (3) µm long with 9–14 side teeth (Figure 2); long spur of mid tibia 66–77, 73 µm long with 17–19, 18 side teeth, short spur 57–68, 63 µm long with 11–16, 14 side teeth (Figure 3); long spur of hind tibia 80–89, 86 µm long with 6–9, 8 side teeth, short spur 57–65, 62 µm long with 9–12, 11 side teeth (Figure 4). Fore tibia apparently without comb. Comb of hind tibia with 8 strong setae, longest 69–76, 73 (4) µm long; shortest 48–52, 50 (4) µm long. Claws on all legs long and slender, distally pointed, spinulate in basal 1/3.</p><p>Hypopygium (Figures 5–6). Tergite IX with 9–13 (3) setae in single to partly biserial posterior row. Gonocoxite 154–160 (3) µm long; gonostylus slender, 139–146 (3) µm long; megaseta 12–14 (3) µm long.</p><p>Pupa (n = 8–10). Total length 5.25–6.98, 6.03 mm.</p><p>Coloration. Brown.</p><p>Cephalothorax. Thoracic horn (Figure 8), somewhat triangular, curved; 372–448, 404 µm long; 140–176, 160 µm wide at its widest point; plastron plate 196–256, 214 µm long; external membrane with distinct spines; horn sac not quite filling horn lumen. Thoracic membrane with transverse ridges extending to median suture. Thoracic setae Dc 1 simple, pointed, about 60 µm long; Dc 2 not discernable; Sa simple, pointed, about 160 µm long.</p><p>Abdomen (Figure 7). Scar on tergite I elongate and pigmented. Shagreen spines (Figure 9) short, blunt, and partially serially arranged in groups of 2–4. Abdominal setae D 1 on tergites II–VII large, spine-like and arising from large, prominent tubercles; tergite II: D 1 100–128, 112 µm long, tubercle 88–120, 103 µm long measured along inner margin; tergite III: D 1 116–136, 127 µm long, tubercle 160–188, 174 µm long; tergite IV: D 1 140–160, 151 µm long, tubercle 192–236, 217 µm long; tergite V: D 1 140–160, 151 µm long, tubercle 212–256, 227 µm long; tergite VI: D 1 140–160, 153 µm long, tubercle 188–220, 199 µm long; tergite VII: D 1 136–164, 153 µm long, tubercle 112–136, 139 µm long. Remaining D and V setae of varying size; D 2 and D 3 on tergite III–V arising from small tubercles. Segments I–VI with 2 L setae; segment VII with 4 short LS setae; segment VIII with 5 LS setae, longest about the length of the segment.</p><p>Anal lobe (Figure 10) 458–572, 515 µm wide, 580–669, 641 µm long. With simple spine shagreen laterally. Outer border with fringe of setae-like spinules gradually reduced to indistinct spines at the distal end; inner border divergent, without fringe, but with few, small, indistinct spines preapically in some specimens. Anal macrosetae arise from basal 1/4, about 0.75 times segment length.</p><p>Larva.
