Description: Body 1.55-1.85 mm long, generally entirely reddish with slightly darkened abdomen, some specimens darker; palpi yellowish.

Male: Head as in Figs 58, 60 & 62 View Figs 57-62 , very wide, with slightly raised occipital region and frons, the latter flattened laterally with enlarged and sharp lateral margins, and crossed by transverse wide U-shaped sulcus originating posterior to antennal tubercles; frontal lobe very large and slightly convex, punctate and with slight medial carina separated from frons by prominent ridge angled posteriorly at middle. Antennae ( Fig. 19 View Figs 16-22 ) with scape and pedicel longer than wide; antennomeres III-VII about as long as wide; antennomere VIII wider than long; antennomere IX slightly wider than VIII and slightly wider than long; antennomere X distinctly wider than long and wider than IX; antennomere XI moderately elongate, about as long as VII-X combined. Metaventrite with deep and wide transverse sulcus on apical two-thirds, sulcus with prominent margins. First abdominal sternite slightly raised and flattened at middle; remaining abdominal sternites flattened at middle. Mesotibiae with distal half swollen and densely pubescent. Aedeagus ( Fig. 6 View Figs 1-6 ) 0.265 -0.275 mm long, with ovoidal dorsal plate narrowed apically; dorsal longitudinal struts slightly divergent. Parameres relatively wide with very large and long recurved seta on well-developed outer lobe; apical portion of parameres slightly enlarged, prolonged laterally as short spine; apex bearing two long ventral medial setae. Copulatory pieces consisting of pair of subequal and short lateral sclerites that are slightly enlarged at apex, recurved, and more robust basally.

Female: Similar to male except head not modified; antennae shorter; eyes smaller; metaventrite, abdominal sternites, and legs unmodified.

Collecting data: The label data indicate a very long collecting period from November to July.

Distribution: Achilia temporalis   occurs in Central Chile (Región Valparaíso and Región Coquimbo) from San Antonio to Choapa Provinces ( Fig. 64 View Fig : green squares).

Comments: We have examined the holotype of A. caneloi Franz, 1996   . Despite its missing abdomen (lost by Franz) we identifed it as a female (and not a male as stated by Franz) of A. temporalis   , and consequently place A. caneloi Franz, 1996   as a junior synonym of A. temporalis Jeannel, 1962   (syn. nov.).

The males of A. temporalis   are easily distinguished from other species of the A. cosmoptera   group by the shape of the head ( Figs 58, 60, 62 View Figs 57-62 ), antennae ( Fig. 19 View Figs 16-22 ) and aedeagus ( Fig. 6 View Figs 1-6 ). For characters to distinguish the females of A. temporalis   from those of A. bifrons   see the “Comments” section of the latter species.
