Colliuris ludoviciana ( Sallé, 1849)

Casnonia ludoviciana Sallé, 1849: 297 . Type locality: «Nouvelle-Orléans (Louisiane)» (original citation). - LeConte (1880: 85).

Colliuris ludoviciana: Liebke (1930: 660) ; Lindroth (1969: 1008); Downie and Arnett (1994: 187); Downie and Arnett (1996: 207); Ciegler (2000: 117).

Type material. Sallé’s description of this species was based on two specimens. Chaudoir (1863: 277) reported that one of the two original specimens was given to him by Sallé and that the other was sent to LeConte. The description and provenance leave no doubt as to the interpretation of this species.

Description. COLOR. Head black with basal fifth reddish-yellow to light red, pronotum black with apex and base reddish-yellow to light red, elytra reddish-yellow to light red with broad, median, transverse band and apex black; metasternum and metepisternum light red, abdominal sterna contrastingly darker, reddishblack; antennomeres 1–3 and base of 4 yellow, antennomeres 5–7 yellowish-brown to blackish-brown, antennomeres 8 and 9 white though apical half of 9 infuscate in some specimens, antennomere 10 and 11 darker, brown; femur yellow usually with apical half (except apex) slightly darkened, tibia light brown with submedian white band. MICROSCULPTURE. Body without meshes or microlines dorsally. HEAD. Posterior supraorbital seta located behind level of posterior edge of eye. PROTHORAX. Pronotum without transverse wrinkles except at base in most specimens; side with one seta. ELYTRA. Interval 3 with six to nine discal setae, interval 5 with two to five discal setae, interval 7 without discal setae. Striae 2–5 moderately finely punctate on basal half, remaining ones not or very finely punctate. Intervals 2–4 or 3 and 4 with shallow depression before middle of elytra; intervals 7 and 8 with faint, barely distinct, preapical swelling. ABDOMEN. Sterna with sparse pubescence. MALE GENITALIA. Median lobe as illustrated ( Fig. 15 ).

Body length: 6.4–8.6 mm.

Geographical distribution. This species inhabits the Coastal Plain; it ranges from southeastern New York to southern Florida, west to eastern Louisiana ( Fig. 20 ). The species was also recorded from "N. Yucatan" by Liebke (1938: 56) and from "P[ennsylvani]a" by Leng (1920: 65). Both records are suspect.

Habitat. Adults of this species are found mainly along the edges of swamps, marshes and eutrophic ponds, on wet, muddy or sandy soil covered with some vegetation, particularly grasses ( Larochelle and Larivière 2003: 211).

Note. This species seems out of place among the other ones included in the same species group because of its very characteristic body coloration. Nevertheless all other structural features studied clearly suggest that it is closely related to them.
