Type locality

UNITED STATES: District of Columbia [exact locality uncertain].

Type material

Neotype, here designated (CMNH): “D.C.” / “Henry Ulke Beetle Coll. CMNH Acc. No. 1645”/”NEOTYPE Hister aeneomicans Horn, 1873, Desg. Caterino & Tishechkin, 2012”. This species was originally described by Horn from “one specimen in the cabinet of Mr. Ulke, collected in the District of Columbia” (Horn, 1873: 295). Therefore there was a unique holotype at one time. The specimen was returned to Ulke, whose collection now resides in the Carnegie Museum, and mixed with other specimens with identical data. Therefore the holotype is technically lost (though probably still in existence), and a Neotype is needed. We select one of three possible specimens with identical data to the original type, the most well preserved and intact. We have not dissected this specimen to confirm sex. However, this species is morphologically uniform throughout its range and there are unlikely to be any ambiguities with its identification in the future.

Male genitalia (Figs 39A–C, E, I–J): T8 narrowly, rather deeply emarginate, ventrolateral apodemes with inner apices widely separated, projecting beyond ventral midpoint, obsolete apically, apical margin shallowly emarginate; S8 with halves fused along midline, basal emargination broad, deep, basal apodemes widely separated, sides sinuately narrowed, apices obliquely truncate, densely setose, widely separated by acute apical emargination; T9 with short basal apodemes, halves nearly meeting dorsobasally, ventrolateral apodemes bluntly produced beneath, nearly to midline, apices narrowly rounded, with single seta borne on subapical tubercle on each side; T10 narrow, finely emarginate apically; S9 with long narrow, medially keeled stem, head rounded to near apex, apices subacute, apical emargination broad, sinuate; tegmen with base rather broad, weakly narrowed to apex, apices narrowly rounded, tegmen strongly curved dorsoventrally, mainly near base, with eversible subapical denticles; median lobe about one-third tegmen length, simple; basal piece about one-third tegmen length.

Remarks

Baconia aeneomicans is among the very few metallic species in this species group (Fig. 38A), and this in combination with its distribution makes its identification straightforward. It is sympatric with only two other North American Baconia species, Baconia venusta, which is much larger, with a larger, more convex, less distinctly punctate body (Figs 11C–F; in addition to lacking all the characters of the Baconia aeneomicans group in general), and Baconia stephani sp. n., described below. The latter is rather similar, but may be easily separated by its non-metallic coloration, more narrowly elongate body, and more coarsely and completely punctate pronotum.
