Semiardistomis puncticollis ( Dejean, 1831)

( Figs 6 , 17 , 33 )

Clivina puncticollis Dejean 1831: 508 . Type locality: "Amérique septentrionale", herein restricted to Highlands Hammock State Park, Hardee Co., Florida, U.S.A.

Ardistomis puncticollis: Putzeys (1846: 647) ; LeConte (1857: 80); LeConte (1879: 32); Blatchley (1910: 63); Downie and Arnett (1996: 111, 112).

Semiardistomis puncticollis: Nichols (1988a: 187, 192); Ciegler (2000: 43).

Type Material. Dejean originally described this species from an unspecified number of specimens. According to Putzeys (1846: 647), Dejean's collection includes a single specimen under that name. The syntype, a female located in MHNP, is labelled "36 [handwritten]/ puncticollis Dej. Am. bor. Dej. [handwritten]/ Lectotype Clivina puncticollis Dej. des. S.W. Nichols 1984" (fide Nichols 1988a: 192). The lectotype designation is hereby published. This species was not surveyed by Lindroth (1955), who reported on Dejean's types of North American Carabidae .

Diagnosis. Distinguished from all other Nearctic Ardistomina by the presence of extra supraorbital setae and of discal setae on the pronotum.

Description. Same character states as for S. viridis except for the followings. Head: Eyes slightly less globulose. Frons with five to seven supraorbital setae on each side. Mentum tooth not cariniform; setae behind tooth distant. Prothorax: Pronotum with more than ten lateral and sublateral setae; disc with setae. Elytra: Striae (except sutural stria) not impressed; striae 2 and 4 with more setae. Lateral margin not prolonged in form of carina from basal extremity to base of stria 3. Male Genitalia: Median lobe more regularly curved in lateral view ( Fig. 6 ). Female Genitalia: Seminal tube of spermatheca ( Fig. 17 ) somewhat widened apically.

Body length: 4.8–6.5 mm.

Geographical Distribution. This species ranges from western Missouri to Virginia, south to Florida (not yet recorded from the Keys) and eastern Texas along the Rio Grande ( Fig. 33 ).

Habitat. Adults of this species were collected on eroding river bank in northern Florida ( Choate & Rogers 1976: 364).

Comments. Nichols (1988a: 193, 195) reported that this species is "brachypterous or fully­winged" and that the species was "relatively common at a blacklight operated just outside the laboratory building at Archbold Biological Station". I did not investigate the wing condition of this species.
