THE COLEOPTERISTS BULLETIN 56(3), 2002 403
Holotype. Male. Length 10.9 mm. Width 6.0 mm. Color: head and elytron light brown, pronotum dark brown with greenish reflections. Head: Figure 4 View Figs . Dorsal surface densely
punctate and moderately setose; punctures moderatelysized; setae long, slender, tawny. Frontoclypeal suture weakly bisinuate. Labrum with apex vertically produced with respect to clypeus, weakly produced at middle, rounded. Maxillary palpus with terminal segment enlarged, with deep sulcus. Mentum with surface moderately setose, apex acuminate. Antenna 10segmented (segments 5 and 6 partially fused making antenna appear 9segmented); club elongated, flattened, longer that combined basal segments (club length approximate to head length). Pronotum: Form widest at middle, midline absent (weakly punctate in other individuals). Surface densely punctate, moderately setose; punctures moderatelysized; setae long, slender, tawny. Scutellum: Shape parabolic: 1.3 times wider than long medially. Surface densely punctate, setose; punctures moderately large; setae long, slender, tawny. Elytron: Surface glabrous. Longitudinal striae punctate; punctures moderatelysized, separated by 2–6 puncture widths. Intervals sparsely punctate with moderatelysized punctures. Epipleuron with row of dense setae ventral to bead. Pygidium: Width 2.3 times length medially. Surface sparsely punctate, moderately setose; punctures moderatelysized; setae tawny. Venter: Thorax densely setose; setae long, tawny. Legs: Protibia with 3 subequally large teeth. Tarsal claws with modified claw slightly thickened when compared to other claw, apex bifurcate (similar to Fig. 7 View Figs ). Tarsomere 5 without ventromedial tooth (similar to Fig. 6 View Figs ). Meso and metatibia with apical spurs slender, acute. Mesotibial apex with 17 spinules. Metatibial apex with 25 spinules. Parameres: Figure 12 View Figs . Basally with broad, medial furrow.
Variation. (34 paratypes). Length 10.9–16.6 mm. Width 6.0– 8.6 mm. Color of elytron light to dark brown. The paratypes do not differ significantly from the holotype. Female unknown.
Etymology. From the latinized adjective for ‘‘Aconcaguan,’’ referring to the region in Chile in which this species is found and the province where most of the type series was collected.
Diagnosis. This species is distinguished from all other species in the genus Aulacopalpus by the following combination of characters: antennal club elongated in males (length equal to or slightly shorter than head); pronotum green to greenish brown when viewed without magnification; elytron brown, glabrous; all tarsal claws with modified claw slightly thickened when compared to other claw and with apex bifurcate (males); tarsomere 5 without ventromedial tooth; parameres basally with broad, medial furrow.
Distribution (Map 1). Coastal Chile from Coquimbo to Santiago.
