Figs 2, 16, 26, 44, 46, 48, 63

Holotype: MHNG (# MHNG-ENTO-85480); 1 ♂; SOUTHERN CHILE: Región Los Lagos: Osorno Prov.: Puyehue National Park, Antillanca road; 500-1000 m; 18-20. XII.1984; car netting; S. & J. Peck.

Description: Body 1.15 mm long, dark with dark reddish elytra, antennae, legs, and palpi.

Male: Head as in Figs 44, 46 & 48, wide. Occipital region and median part of frons raised; frons flattened laterally and confluent with deep and large transverse sulcus delimiting it from frontal lobe; anterior part of frontal lobe prolonged posteriorly as short median process; sides of frons slightly sharp; surface of frontal lobe with sparse punctures.Antennae (Fig. 16) with scape distinctly longer thanwide; pedicelslightlylongerthanwide; antennomeres III and V about as long as wide; antennomeres IV and VI-VII slightly wider than long; antennomere VIII wider than long; antennomere IX wider than VIII and distinctly wider than long; antennomere X distinctly wider than long and wider than IX; antennomere XI elongate, longer than VII-X combined. Metaventrite with deep and wide medial semioval impression on apical half, impression sparsely pubescent and punctate. Protibiae with distal half slightly swollen; mesotibiae (Fig. 26) with two small subapical spurs on medial margin, distal half swollen and densely pubescent; metatibiae with distal half slightly arcuate. Aedeagus (Fig. 2) 0.21 mm long, with suboval dorsal plate distinctly narrowed and frayed apically; dorsal longitudinal struts divergent. Parameres relatively wide with very large and long recurved seta on well-developed outer lobe; apical portion of parameres prolonged laterally as short tip; apex bearing one ventral long medial seta. Copulatory pieces consisting of a pair of subequal sclerites that are rounded apically, recurved and more robust basally.

Female: Unknown.

Collecting data: The only specimen was collected in December by car netting at an elevation of 500- 1000 meters.

Distribution: Achilia covidia n. sp. is only known from Puyehue National Park (Región Los Lagos: Osorno prov.) (Fig. 63: blue triangles).

Comments: The males of A. covidia n. sp. are easily distinguished from other species of the A. cosmoptera group by the shape of the head (Figs 44, 46, 48), antennae (Fig. 16), and aedeagus (Fig. 2).

Etymology: The epithet of this new species refers to the COVID-19 pandemic and the periods of quarantine during which this study was carried out by the authors.
