Newton & M. Thayer;   Nothofagus ssp. forest, flight intercept trap.   Description:Body 1.45 mmlong, reddish-brown, with darker abdomen, and reddish elytra; antennae, palpi and legs yellowish. Head with weakly protruding eyes, shorter than convex temples. Pronotum as wide as head; median antebasal fovea smaller than lateral ones. First abdominal tergite with basal striae extending to about one-third of paratergal length, and separated at base by about one-third of tergal width.  Figs 51-56. (51-53)  Achilia adorabilis n. sp.(54-56)  A. nipponobythoides n. sp.Male left antenna in (51, 54) dorsal, (55) oblique, (52, 56) frontal and (53) ventralviews.  Male: Head as in Figs 47-48; frons with finely punctate and pubescent median depression with margins markedly raised and punctate, slightly expanded above eyes, the latter areas flattened and more densely punctate; anterior sides of head convergent. Antennae ( Figs 17, 49-50) with scape and pedicel distinctly longer than wide; antennomere III as wide as long, antennomeres IV-V transverse; antennomere VI more than two times longer than wide with concave mesal margin; antennomere VII distinctly transverse; antennomere VIII transverse, its mesal margin projecting in large lamina; antennomere IX with mesal margin projecting in a long bilobed lamina bearing long and large apical setae; antennomere X strongly transverse, apical third of mesal margin projecting and bearing three long and thin setae; antennomere XI elongate and longer than VII-X combined, its surface with many tubercles. Metaventrite at middle slightly raised with faint median sulcus. Legs with trochanters very elongate; protrochanters bearing tuft of setae; ventral margin of mesotrochanters projecting posteriorly as short spine ( Fig. 24); profemora and mesofemora slightly thickened; distal half of metatibiae slightly sinuate. Abdominal tergites and ventrites unmodified. Aedeagus ( Fig. 6, dorsal longitudinal struts not shown) 0.30 mmlong; medial sclerites apically pointed, and associated on each side with one pointed sclerite.  Female: Unknown.   Collecting data:Only one specimen collected in December in  Nothofagus ssp. forestby flight intercept traps.   Distribution:  Achilia trulla n. sp.is known only for the typelocality in Region of Los Lagos(Osorno province) ( Fig. 58: yellow stars).   Comments:  Achilia trulla n. sp.is easily distinguished from the other members of the genus by the morphology of the male head ( Figs 47-48), features of the antennae ( Figs 17, 49-50), and shape of the aedeagus ( Fig. 6). 2575115333 1982-12-18 1982-12-24 1982-12-18 FMNH A.
