Macrohydnobius tibiocalcaris Peck & Cook View in CoL , new species
( Figs. 107 View FIGURE 107 , 140–142 View FIGURES 140–142 )
Type material. Holotype: ♂ ( CMNC). CANADA: Ontario: Chaffeys Locks, Queens University Biology Station , 2–23.XI.1980, S. Peck, forest malaise and intercept traps.
Diagnostic description. Body yellowish to reddish brown, moderately shining. Length of pronotum + elytra = 5.4 mm (male). Head finely, sparsely punctate, with irregular depressed area between eyes. Pronotum widest at basal one-third; sides obtusely angulate at basal one-third, apical two-thirds weakly concave; basal angles obtuse; with a pair of small basal impressions joined by a transverse, closely punctate, impressed line; ratio length:width = 1:1.5; moderately coarsely punctate with microsculpture of short, irregular lines. Elytra elongate, wider than pronotum, ratio length:width = 1:0.6; with 9 regular, closely punctate striae; striae 6 and 7 do not reach apex, stria 1 impressed posteriorly; intervals with 2–3 rows of fine punctures and transversely striolate; uneven intervals with scattered larger punctures. Antennal club ( Fig. 140 View FIGURES 140–142 ) moderately broad, ratio club width:length = 1:2.6; width ratio of antennomeres 7:8:9 = 1.5:1:1.7. Mandibles elongate; left mandible with tooth on outer margin and on apical one-half of inner margin; right mandible strongly curved apically. Male metatrochanter without a subapical tooth. All femora unarmed. Male protibia ( Fig. 141 View FIGURES 140–142 ) broad at apex, outer margin spinose; an elongate, sinuate spur inserted before apex. Male mesotibia and metatibia broad at apex, spinose. Male. Aedeagus ( Fig. 142 View FIGURES 140–142 ) with median lobe elongate, broad, apical one-fifth tapering sharply to narrow apex. Parameres inserted at about middle, broad at base, inner margin sinuate, narrow apically, with three apical setae. Female. Unknown.
Bionomics and distribution. Known only from the type specimen and type locality, a deciduous forest in eastern Ontario ( Fig. 107 View FIGURE 107 ), collected in September .
Etymology. Named with reference to the elongate spur (Latin, calcar) inserted before the apex of the tibia in the male of this species.
