Ischasioides giesberti sp. nov. (Fig. 11) Diagnosis. Ischasioides giseberti differs from I. crassitarsis (Gounelle, 1911) and I. gounellei Tavakilian & Peñaherrera-Leiva 2003, mainly, by the presence of goldish band of pubescence on pronotum (absent in those species). Etymology. Ischasioides giseberti is named for Edmund Giesbert, who collected the type specimen. Female (Fig. 11): Integument dark-brown; the following reddish-brown: head, base of elytra (mainly on disc), mandibles (except apex, which is black), basal fourth of elytra, scape; prothorax orange, with anterior and posterior margins brown; peduncle of femora yellowish, clavate portion brown; tibiae dark, metatibiae almost black. Dorsal surface of head coarsely, abundantly punctate; pubescence moderately abundant, mixed with some long setae on vertex; and some very long setae near clypeus. Clypeus with pubescence as on dorsal surface of head, mixed with moderately abundant long setae, and a very long seta on each side. Labrum with long, abundant setae. Outer surface of mandibles with one very long seta on base and some long, sparse setae on the remaining area. Laterally, below inferior ocular lobes, about four very long setae. Ventral surface finely transversely sulcate, with moderately short, sparse setae. Scape, pedicel, and antennomeres III–VI with very long, dark, thick setae. Pronotum abundantly pubescent, mixed with long, moderately abundant setae; disc on each side with a semicircular band of golden pubescence, fused on anterior fourth. Basal two-thirds of prosternum abundantly pubescent, with long setae; distal third, shining, glabrous and shallow. Elytra moderately abundantly pubescent, and with sparse, long setae (more so on basal half). Metasternum and metepisterna pubescent, with long, sparse setae. Ventrites laterally pubescent, centrally with sparse, very long setae. Femora, tibiae, and tarsi with very long setae. Pronotal punctation moderately coarse, very abundant. Elytra microsculptured; punctation coarse, moderately abundant. Length of area between base of inferior ocular lobe and apex of labrum equal to 0.8 times length of one inferior ocular lobe. Distance between inferior ocular lobes equal to 0.8 times length of one lobe in frontal view. Antennae 1.6 times as long as elytral length; apex of antennomere XI reaches elytral apex; antennomeres III–V filiform, slightly widest at apex; antennomeres VI–VII distinctly enlarged from base towards apex; antennomeres VIII–XI almost moniliform. Elytra reaching apex of first abdominal segment, dehiscent at sutural fourth; elytral fourth feebly tumid. Metafemora almost reach abdominal apex. Metatarsomere I about 1.3 times longer than II–III together. Dimensions in mm (holotype female). Total length (from mandibular apex to abdominal apex), 5.30; prothorax: length, 1.20; anterior width, 0.70; posterior width, 0.70; humeral width, 0.85; elytral length, 2.10. Type material. Holotype female, from ECUADOR, Napo: 24 km E Atahualpa (480 m), X.16 –23.1995, E. & V. Giesbert col. (FSCA).
