Type material (1 ex.): CENTRAL CHILE: Región O’Higgins: Cachapoal Prov.: MNHN; 1 ♀ (holotype); labels verbatim “Holotype / Palmas de Cocálan / Achillia melanocephala nov. (handwritten by Jeannel)” .

Description: Male: Unknown.

Female: Body 1.40 mm long, reddish brown with darkened head and abdomen; antennae and legs reddish; palpi yellowish. Head with frons and occipital region slightly convex; frontal lobe short, separated from frons by shallow transverse sulcus. Antennae with scape and pedicel slightly longer than wide; antennomeres III- VIII wider than long; antennomere IX wider than VIII, distinctly wider than long; antennomere X wider than IX, distinctly wider than long; antennomere XI moderately elongate, shorter than VII-X combined.

Collecting data: No data available.

Distribution: Achilia melanocephala is only known from Cachapoal Province (Región O’Higgins) ( Fig. 64 View Fig : triangles edged in blue).

Comments: The holotype of A. melanocephala is a female very similar to those of A. angularis . However, since it was collected in a region quite distant from where A. angularis is known, we prefer at present to maintain A. melanocephala as a valid species. Its status should be reassessed once additional specimens, notably males, are available from or near the type locality.
