( Fig. 4 , 18 )

Anogdus luggeri Hatch, 1927: 17 . Holotype, female, in UMSP, seen. Type locality: Minnesota; no other data.

Cyrtusa luggeri (Hatch) ; Brown 1937b: 171.

Liocyrtusa luggeri (Hatch) ; Daffner 1985: 695; 1988: 286.

Diagnosis. Length (pronotum + elytra) = 1.49–2.16 mm; greatest width = 0.98–1.42 mm. Reddish brown, moderately shiny. Fine, irregular microsculpture scattered on head and pronotum, more prominent on elytra. Head with fine, moderately spaced punctures anteriorly; punctures larger and more closely spaced on vertex. Antennal club variable in width; antennomere 8 thin and about half width of antennomere 7; apical antennomere clearly narrower than 9 and 10. Sides of pronotum rounded, posterior angles obtuse. Pronotum moderately finely, sparsely punctate medially, punctures more closely spaced laterally. Elytral strial punctures coarse, separated by less than one diameter, visible to base of pronotum; interstrial punctures smaller and more widely spaced. Metasternum coarsely punctate, punctures more densely spaced laterally, with impunctate area medially. Metatibia broad, with apex about three times width at base. Male mesotibial process triangular. Abdominal sternite III rugose, sternites IV–VII each with row of fine punctures before apex. Median lobe of aedeagus broad; apical lobes short with rounded apices ( Fig. 4 ). Parameres ( Fig. 4 ) broad, with membranous apices extending beyond apices of median lobe. Internal sac as in Fig. 4 .
