Description: Body 1.35-1.40 mm long, dark brown with reddish elytra; antennae and legs reddish; palpi yellowish.

Male: Head as in Figs 38, 40 & 42 View Figs 37-42 , very wide, surface with some very scattered punctures; occipital region raised, frons flattened and separated by large transverse sulcus from large frontal lobe; anterior margin of frontal sulcus slightly raised and pointed at middle. Antennae ( Fig. 17 View Figs 16-22 ) with scape and pedicel longer than wide; antennomere III distinctly longer than wide; antennomere IV about as long as wide; antennomeres V-VII slightly longer than wide; antennomere VIII as long as wide; antennomere IX wider than VIII and wider than long; antennomere X distinctly wider than long, shorter and wider than IX; antennomere XI elongate, longer than VII-X combined. Metaventrite with deep and wide transverse sulcus on apical twothirds, sulcus with deflected and posteriorly prominent margins forming sort of tubercles. First abdominal sternite slightly raised and flattened at middle; remaining abdominal sternites slightly flattened at middle. Protibiae with distal half slightly swollen; mesotibiae ( Fig. 27 View Figs 23-32 ) with distal half swollen and densely pubescent. Aedeagus ( Fig. 3 View Figs 1-6 ) 0.23 mm long, with dorsal plate subrectangular; dorsal longitudinal struts divergent. Parameres relatively wide with very large and long recurved seta on welldeveloped outer lobe, this seta bifid and very swollen on basal third; apical portion of parameres slightly recurved anteriorly and prolonged laterally at tip; apex of parameres bearing one long ventral medial seta associated with wider and shorter seta. Copulatory pieces consisting of two subequal short sclerites slightly enlarged apically, recurved and more robust basally.

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

Collecting data: The data in our possession do not allow us to make statements in this regard.

Distribution: Achilia blanchardi   is only known from Valdivia (Región Los Ríos: Valdivia Prov.) ( Fig. 63 View Fig : green diamonds).

Comments: Raffray (1904: 138) proposed the new name Achilia blanchardi   for Bryaxis valdiviensis Reitter, 1883   , described on an unspecified number of specimens from Valdivia, because this name was preoccupied by Pselaphus valdiviensis Blanchard, 1851   [now Achilia valdiviensis ( Blanchard, 1851)   ] (see Sabella et al., 2020: 140, 144-145).

Jeannel (1962: 430) listed Achilia clavata Raffray, 1904   as a junior synonym of A. blanchardi   , but without justifying this action. We have examined the holotype of A. clavata   , which is a female resembling in all features those of A. blanchardi   , and therefore we confirm the synonymy proposed by Jeannel.

Jeannel (1962: 430) stated that the type of Achilia blanchardi Raffray, 1904   was housed in the MNHN collections. In the MNHN we found in Raffray’s collection a series of 11 specimens identified by Raffray as Achilia blanchardi   ; the first specimen of the series is a male labeled “Type / 1880; Chili; Valdivia; leg. Kindermann/ Bryaxis   ; valdiviensis   ; m. Valdivia / Museum de Paris; 1917; coll. Raffray / A. blanchardi   ; A. Raffray det.” which we designate here as the lectotype of A. blanchardi Raffray, 1904   ( Blanchard, 1851), and the remaining 10 specimens (1 male and 9 females) labeled “ Chili ” without further label data are designated as paralectotypes.

Within the A. cosmoptera   group the males of A. blanchardi   are easily distinguished from other species by the shape of the head ( Figs 38, 40, 42 View Figs 37-42 ), antennae ( Fig. 17 View Figs 16-22 ) and aedeagus ( Fig. 3 View Figs 1-6 ). The females of this species are very similar to those of A. elfridae   , from which they can be distinguished by their wider head with a wider frontal sulcus, and their slightly longer antennomere XI (0.16 mm for A. blanchard   i vs 0.14-0.15 mm for A. elfridae   ).
