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 View Figs 43-48 , 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 View Figs 16-22 ) 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 View Figs 23-32 ) with two small subapical spurs on medial margin, distal half swollen and densely pubescent; metatibiae with distal half slightly arcuate. Aedeagus ( Fig. 2 View Figs 1-6 ) 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 View Fig : 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 View Figs 43-48 ), antennae ( Fig. 16 View Figs 16-22 ), and aedeagus ( Fig. 2 View Figs 1-6 ).

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.
