Selenophorus palliatus (Fabricius) ( Fig. 38 )

Carabus palliatus Fabricius 1798: 58 . Type locality: North America. Types: Zoologisk Museum, Universitets Copenhagen, Denmark.

Selenophorus stigmosus Germar 1824: 25 . Type locality: Georgia. Types: probably lost.

Selenophorus impressus Dejean 1829: 82 . Type locality: North America. Types: MNHN.

Harpalus laesus LeConte 1858: 59 , new synonymy. Type locality: Texas ( Fort Gates , Coryell Co.) and Mexico ( Tampico , Tamaulipas) . Types: MCZ #5914.

Descriptive Notes. Elytra with seriate punctures foveate. Pronotum broad, lateral sides not noticeably converging posteriad; hind angles widely rounded; base almost as wide as elytral base; anterior margin with angles projected, span wide compared to head size. Median lobe described above. Males + ♂ 1. An aberrant extra left anal seta was observed in only two males: Texas, Victoria Co. (PWMC); Florida, Palm Beach Co. ( FMNH). ABL 7.0– 8.7 mm .

Range. USA: AL, AR, FL, GA, sIL, LA, MS, NC, OK*, SC, TX, VA*; Mexico; West Indies.

Remarks. The male holotype of Harpalus laesus LeConte is associated with label “ H. (S.) laesus Lec. Hald. palliatus 6”. Its image at mczbase.mcz.harvard. edu/guid/MCZ:Ent:5914 yields ABL approximately 8.3 mm.

Horn (1880: 180) regarded S. palliatus with slightly larger punctures as a synonym of S. laesus . Casey (1914: 146) reported the main distinction of S. laesus from S. palliatus is that the seriate punctures are much smaller, not conspicuously foveate as in palliatus . Bousquet (2012: 1143) listed S. laesus as a valid species with the geographic range of central TX,?AZ, and Mexico.

The image of the type specimen (MCZ), and additional high-resolution images of a specimen (USNM) identified as S. laesus by Casey, do not show significant puncture size differences from S. palliatus in our opinion. Based on a study of extensive Texas material, we concluded that S. palliatus is an anatomically variable species (even among individuals in same series) with regard to body size, pronotal shape, and the size of seriate punctures. Selenophorus laesus represents one expression in a morphological continuum of S. palliatus . Little or no differences were noted in the male genitalia.
