Description: Body 1.45-1.65 mm long, entirely reddish, some specimens with slightly darkened abdomen; palpi yellowish.
Male: Head as in Figs 52, 54 & 56 View Figs 51-56 , wide, with slightly raised occipital region and frons; frons flattened laterally with sharp and subparallel sides, separated from frontal lobe by deep and flatten narrowed transverse sulcus. Antennae ( Fig. 20 View Figs 16-22 ) with scape distinctly longer than wide; pedicel and antennomere III slightly longer than wide; antennomere IV about as long as wide; antennomeres V-VII longer than wide; antennomere VIII slightly wider than long; antennomere IX wider than VIII and wider than long; antennomere X distinctly wider than long and wider than IX; antennomere XI elongate, about as long as VII-X combined. Metaventrite with apical portion crossed on two thirds by deep and wide medial suboval impression, impression with prominent margins. First abdominal sternite slightly raised and flattened at middle; remaining abdominal sternites flattened at middle. Mesotibiae ( Fig. 29 View Figs 23-32 ) with distal half swollen and densely pubescent, with stout subapical mesal spine. Aedeagus ( Fig. 13 View Figs 7-15 ) 0.25-0.26 mm long, with ovoidal dorsal plate narrowed and frayed at apex; dorsal longitudinal struts slightly divergent. Parameres relatively wide with large and long recurved seta on well-developed outer lobe; apical portion of parameres slightly enlarged and prolonged laterally as short spine; apex bearing one ventral median seta. Copulatory pieces consisting of a pair of short subequal lateral sclerites recurved and more robust basally.
Female: similar to male except head not modified; antennae shorter; eyes smaller; metaventrite with shallow and narrow medial sulcus; abdominal sternites, and legs unmodified.
Collecting data: The label data indicate a very long collecting period from August to April.
Distribution: Achilia pandemica n. sp. occurs in Central Chile (Región Bío Bío and Región Maule) from Concepción to Curicó Provinces ( Fig. 64 View Fig : circles edged in green).
Comments: The males of A. pandemica n. sp. are easily distinguished from other species of the A. cosmoptera group by the shape of the head ( Figs 52, 54, 56 View Figs 51-56 ), and antennae ( Fig. 20 View Figs 16-22 ). The aedeagus is very similar to that of A. temporalis , but the shape of the parameres is distinctive. The females of A. pandemica n. sp. are similar to those of A. temporalis , from which they can be distinguished by their narrower head with the frons slightly convex and flattened anteromedially (distinctly convex and not flattened in A. temporalis ), and mostly by the lateral margins of the frons being subparallel and acute with very prominent antennal tubercles (sides of frons slightly convergent, blunt and with antennal tubercles not prominent in A. temporalis ).
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.
