Chileanthicus penai Werner, 1966: 225 , figs 3, 4, 6.

Type locality. Chile, Atacama, Huasco Prov. , N of Vallenar.

Diagnosis. Body rufous brown, elytra with transverse yellowish band close behind mid-length; body surface rather smooth and glossy, its setation comprising longer erect setae; head rather widely rounded posteriorly; elytra truncate apically; metafemora unidentate, subapical process facing outer side of tibia; male sternum VII modified, its postero-median emargination on each side with 7–8 peg-like setae ( Fig. 49 View FIGURES 45–53 ); paired prongs of male sternite VIII with 6–7 peg-like setae ventrally ( Fig. 50 View FIGURES 45–53 ); tergite VIII with posterior margin rather deeply emarginate medially; segment IX (spiculum) as in Fig. 51 View FIGURES 45–53 ; apical portion of tegmen of aedeagus incised and lobed latero-basally, apex of tegmen widely rounded to subtruncate in ventral view ( Fig. 52 View FIGURES 45–53 ); female sternum VII simple; female tergum VII strongly bulging and with moderate median longitudinal impression ( Fig. 53 View FIGURES 45–53 ); body length (♂ ♀) 2.8–3.6 mm.

C. penai is well-characterized by morphology of apical portion of tegmen (latero-basal incisions, subtruncate apex) and modification of female tergum VII. Both these characters are unique within the Chilean species group.

Type material. Holotype (♂, not examined, MCZC) . Paratypes: 5 ♂♂, 3 ♀♀, CHILE: Atacama Pr.: N. of Vallenar in desert 24 Sept. 1963 under stones L. Peña [p] // PARATYPE Chileanthicus penai ♂ [or ♀] Werner [h] // PARATYPE [p; blue label] ( UAIC, DCDC) .

Additional material. 1 ♀, Chile, Coquimbo, Elqui Prov., Choros Bajos , xi.1997, J. E. Barriga leg. ( JEBC) .

Distribution. Chile (Atacama, Coquimbo, see Remarks).

Remarks. The single female specimen from Choros Bajos (JEBC) displays the external characters of C. penai , including the distinctive form of tergum VII, however, occurrence of C. penai in the Elqui province should be confirmed by examination of a male specimen.
