Eleodes tribulus Thomas, 2005

( Fig. 5C–D )

Amphidora caudata Horn, 1870

Eleodes caudatus ( Horn, 1870) Trichoderulus longipilosus Blaisdell, 1923 Eleodes blaisdelli Doyen, 1979

Diagnosis. Body elongate-ovate, covered in long, pilose setae. Pronotum subquadrate, lateral margins arcuate, narrowing posteriorly, anterior angles rounded, not produced, disc moderately punctate. Elytra with moderate punctures arranged in more or less confused striae, males often with caudal extension of elytra. Profemora unarmed, sometimes moderately sinuate distally. Protarsi lined with dark spicules, plantar surface uninterrupted.

Distribution. Maricopa and Pinal Counties, Arizona. Sonora, Mexico.

Remarks. When synonymizing Trichoderulus with Eleodes, Doyen and Lawrence (1979) refrained from subgeneric placement. Triplehorn and Aalbu (1987) suggested affinities with the subgenus Eleodes based upon the caudal extension of the elytra, but again refrained from placing the species. We also refrain from subgeneric placement, though believe it likely to be allied to E. pilosus , and several other species of Tricheleodes Blaisdell, based on molecular studies (Smith and Johnston, unpublished data) and female genitalia.
