Chileanthicus uhmanni sp. nov.

( Figs 209–211, 225)

Type locality. Australia, Western Australia, ca 15 km SE of Perth, Kenwick , 32°01'S 115°58'E .

Description (female, holotype). Head brown black; pronotum largely reddish brown, moderately darkened anteriorly; elytra black, with rufous brown lateral margins; antennae, palpi and legs rufous brown, femora somewhat darker distally.

Head 1.2 times as long as wide, angulate posteriorly ( Fig. 209); tempora parallel; posterior temporal angles conspicuous. Eyes small, convex. Dorsal surface matte, very densely and distinctly punctured ( Fig. 209); punctation simple, punctures nearly contiguous, evenly spaced, including frontal area (no indication of glosssy median line). Setation short, subdecumbent to appressed, with a few, inconspicuous, short erect setae. Antennae rather long, only slightly enlarged in terminal third ( Fig. 210); antennomere III about twice as long as wide, moderately shorter than IV; antennomere X 1.9 times, XI 2.7 times as long as wide.

Pronotum about as long as wide, slightly wider than head including eyes, moderately widely rounded anteriorly in dorsal view. Pronotal disc convex, its lateral margins forming rather sharp edge (especially close behind the widest point), lateral outlines nearly straightly narrowing towards base in dorsal view. Dorsal surface matte, very densely punctured; punctation and setation as on head.

Elytra 1.7 times as long as wide, conjointly rounded apically. Surface evenly shaped, moderately glossy, distinctly punctured ( Fig. 209); basal punctation conspicuously double, its coarse punctures deep, dot-like, much larger than punctures on head. Setation moderately longer than on head, subdecumbent to appressed, evenly directed posteriad, mostly brownish, with silvery setae forming a narrow longitudinal strip on suture, rather wide transverse band in basal half, widely interrupted medially; erect setae short and inconspicuous.

Metafemora unidentate with nearby edge distinctly angulately protruding ( Fig. 211), subapical process narrow, pointed apically, facing inner side of tibia. Setation rather uniformly short, fine, appressed.

Abdominal sternum VII and tergum VII simple.

Body length (♀). 3.7 mm.

Type material. Holotype: ♀, Kenwick, W. Australien VII.-IX.1960 H. Demarz ( WAM).

Etymology. Named in honour of the late Gerhard Uhmann, well-known German specialist in Anthicidae , who provided me with the type specimen (later placed in WAM).

Differential diagnosis. C. uhmanni sp. nov. seems to be close to C. dentivarius and C. mastersii , with respect to the conspicuous body punctation (clearly double on elytra, Fig. 209), and form of the metafemoral protrusions ( Fig. 211), however it differs clearly by the posteriorly angulate head, and by the setation of the elytra (single silvery setose band, setae rather evenly pointing posteriad, erect setae inconspicuous, Figs 209, 225).

Distribution. Australia (Western Australia).
