Holotype. Male. Length 15.1 mm. Width 8.6 mm. Color: head and pronotum dorsally
copper with strong greenish reflections, elytron greenish-brown; venter yellowish-brown.
Head: Dorsal surface sparsely setose towards margin; setae long, slender, tawny to
cream-colored. Clypeus with surface brown, rugose. Frontoclypeal suture weakly bisinuate.
Frons copper colored with strong greenish reflections, densely punctate, punctures
large. Labrum moderately produced at middle with triangular tooth. Maxillary palpus
with terminal segment enlarged, with deep sulcus. Mentum with surface moderately
setose, apex reflexed into oral cavity. Antenna 10-segmented; club elongated, flattened,
longer that combined basal segments. Pronotum: Midline weakly punctate. Surface moderately
to densely punctate and moderately setose; punctures moderately-sized; setae
long, slender, tawny. Scutellum: Surface densely punctate, setose; punctures moderately
large; setae long, slender, tawny. Shape parabolic: 1.1 times wider than long medially.
Elytron: Surface glabrous, longitudinal striae punctate, weakly impressed; punctures
moderately-sized, separated by 1-4 puncture widths; intervals sparsely punctate with
moderately-sized punctures. Epipleuron with row of dense setae ventral to bead. Pygidium:
Width 2.2 times length medially. Surface sparsely to moderately punctate and moderately
setose; punctures small; setae cream-colored. Venter: Thorax densely setose; setae
long, tawny. Legs: Protibia with 3 subequally large teeth. Protarsal claws with modified
claw slightly thickened when compared with other claw; apex bifurcate. Meso- and metatarsal claws with modified claw with weak ventral tooth near apex,
not thickened when compared with other claw, apex not weakly bifurcate. Tarsomere 5 with ventromedial tooth. Meso- and metatibia with
apical spurs slender, acute (smaller metatibial spur greatly reduced or worn but condition
is not typical). Mesotibial apex with 14 spinules. Metatibial apex with 20 spinules.
Parameres: Figure 20. Basally without broad, medial furrow. |
|
|
| |
Allotype. Female. Length 15.2 mm. Width 8.6 mm. As male except in the
following respects. Legs: Protarsal claws with modified claw with ventral
tooth, not thickened when compared with other claw; apex not bifurcate. |
|
|
| . |
Variation. Based upon eight male and one female paratypes. Length 14.8-
17.3 mm. Width 7.9-8.9 mm. The paratypes do not differ significantly from
the holotype. |
| |
|
| |
Etymology. From the latinized adjective for "Valdivian," referring to the region in Chile in which this species is found and the province where the
entire 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 (length slightly shorter than head); head and pronotum dorsally copper
with strong greenish reflections, elytron greenish-brown; male protarsal claws
with modified claw slightly thickened when compared with other claw and
with apex bifurcate; female protarsal claws with modified claw with ventral
tooth, not thickened when compared with other claw, apex not bifurcate; mesoand
metatarsal claws of both sexes with modified claw with weak ventral tooth
near apex and not thickened when compared with other claw (unique state for
males in this subtribe); and tarsomere 5 with ventromedial tooth; parameres
basally without broad, medial furrow. |
| |
|

Distribution (see map). Known only from Corral, Valdivia, Chile.
Locality Data. Based on 11 specimens examined from BMNH, FMNH,
MNNC, PVGH.

Temporal Data. July (9). |

Remarks. Aulacopalpus valdiviensis is an unusual species because of the
combination of claw characters of the males. This is the only species of
Brachysternina with the modified protarsal claw of the male slightly thickened
when compared with the other claw with the apex weakly bifurcate (normal
for Aulacopalpus), but with the meso- and metatarsal claws with the modified
claw with a weak ventral tooth near the apex and not bifurcate (unique in male
Brachysternina). This combination of male claw characters is seen in some
species of Platycoelia. |
