Anogdus insolitus (Brown, 1937)

( Fig. 7, 8 , 34 )

Neocyrtusa insolita Brown, 1937b: 170 . Holotype male in CNCI, type number 4157; seen by us. Type locality: CANADA: BRITISH COLUMBIA: Penticton.

Anogdus insolitus (Brown) ; Daffner 1988: 276.

Diagnosis. Length (pronotum + elytra) = 1.74–2.68 mm; greatest width = 1.10–1.64 mm. Punctures of head moderate in size, irregularly spaced. Antennal club slender to moderately broad; antennomere 7 distinctly narrower than 9 and 10; antennomere 8 narrow, disk-like; apical antennomere slightly smaller than 9 and 10. Pronotum with sides obtusely angled at posterior two-fifths, posterior angles obtuse. Pronotum finely, sparsely punctate. Elytral strial punctures round and moderately deep, spac- ing ±1 diameter; interstrial punctures slightly finer and more sparse than pronotal punctures; elytral epipleura lack distinct setae. Metasternum at anterior margin with a row of indistinct punctures, smaller than the lateral dense, shallow punctures. Protarsi and mesotarsi of male densely setose ventrally. Male mesotibia weakly curved; mesotibial process broad at base, slender, shorter than large tibial spine. Metafemur moderately robust; males lack a distinct toothlike expansion but may have a weakly rounded expansion near the apex of the lower margin. Abdominal sternites III–VII lack a row of distinct punctures on anterior margin. Median lobe of aedeagus fusiform; dorsal lobes flattened and acutely narrowed apically ( Fig. 7, 8 ). Parameres narrow with weakly widened apices. Armature of internal sac as in Fig. 7, 8 .

Distribution. Canada and USA. Distributed in western North America from the southern parts of western Canada, southwards to California, Nevada, and Colorado ( Fig. 34 ). Previously published dis- tributional records in Brown (1937b: 170) and Daffner (1988: 276): CANADA: BRITISH COLUMBIA: Richmond; Penticton; Nelway (misidentified record of A. potens (Brown) in Daffner 1988: 281 ); SAS- KATCHEWAN: Saskatoon.

Looney, pitfall trap, no fire zone (1, WSUC) ; same data except: 1–8. V.1998 (1, WSUC) ; same data except: 14–28. V.1998, Looney & Zack (1, WSUC) .

Seasonality. Adults are known from the months of May through August.

Bionomics. The predominant habitat seems to be scrubby vegetation, usually on sand, and several specimens were caught in pitfall traps.
