Myrmecium machetero Candiani & Bonaldo, 2017: 29 View in CoL , figs 8, 58 60, 69 70 (♀ holotype from, Yucumo, 15°23’S, 66°59’W, 15–19, Beni, Bolivia, XI.1989, leg. J. Coddington, C. Griswold, D. Silva, S. Larcher, Penaranda, deposited in USNM, not re-examined, ♀ paratype from Reserva Particular Bonanza, 12°31’24.2’’S 71°10’52.7’’W, Manu, Madre de Dios, Peru, 13–14.I.2014, leg. A. Anker & P. H. Martins, deposited in MUSM).
Diagnosis. Males of M. machetero are similar to those of M. urcuchillay sp. nov. by the combined presence of the following characters: carapace and sternum not fused between legs II and III, coxae II and III separated by more than twice coxae II width, carapace smooth, and carapace over leg IV insertion with a conspicuous hump ( Figs 1 View FIGURES 1 A–C). They can be distinguished by the absence of the reservoir’s third fold ( Fig. 1D View FIGURES 1 ).
Description. Male (MUSM-0504851): carapace yellowish-orange, smooth on cephalic region, thoracic region slightly granulose, white short, thin hairs arising from granules ( Figs 1A, B View FIGURES 1 ); sternum coloration as in carapace, smooth with some posterior grains; endites light yellowish-orange; labium yellowish-orange; chelicerae pale yellowish-orange ( Fig. 1C View FIGURES 1 ). Abdomen pale yellow, large caramel-coloured vitreous scutum, with three brown latitudinal bands. Legs I and II yellowish-orange, with prolateroventral brown stripe on Fe, proximal half of the Ti brownish-yellow. Legs III and IV yellowish-orange, Ti and Mt brownish-yellow. Chelicerae: promarginal teeth 3; retromarginal teeth 4. Sternal posterior plate pentagonal. Total length 7.16, carapace 4.35 long, 1.39 wide. Eye diameters: AME 0.14, ALE 0.11, PME 0.14, PLE 0.11. Leg measurements: I—femur 2.26 / tibia 2.31 / metatarsus 1.87; II—femur 1.87 / tibia 1.76 / metatarsus 1.51; III— femur 1.86 / tibia 1.58 / metatarsus 1.56; IV—femur 2.62 / tibia 2.32 / metatarsus 2.56. Leg spination: I—tibia vp0-0-0-1-1, vr0-0-0-1-1; metatarsus vp1-0-1-0-0, vr1-0- 1-0-0. II—tibia vp1-0-1-0-1, vr0-1-0-1-0; metatarsus vp1-0-0-1-0, vr1-0-1-0-0. III—tibia p0-1-0-0-0, r0-1-0-0-0, vp0-1- 0-1-0, vr0-1-0-1- 0; metatarsus p0-1-0-0-0, r0-1-0-0-0, vp1-0-1-0-0, vr1-0-0-0-0. IV—tibia p0-1-0-0-0, r0-1-0-0- 0, vp0-1-0-1-0, vr0-1-0-1-0; metatarsus p1-0-1-0-0, r1-0-0-0-0, vp0-1-0-1-0, vr0-1-0-1-0. Palp: Tibia longer than wide, with ventral excavation; RTA medium-sized in relation to tibia; first fold of reservoir restricted to retrolateral side of tegulum, not touching distal section of reservoir, second fold basal, distal sector sinuous. Tegular neck before embolus insertion present, embolus conical, with few spaced keels ( Figs 1D, E View FIGURES 1 ).
