Notes about types.

This species was described from Pennsylvania from a series of 4 specimens (CMNH) of which we have selected one as lectotype. It is labelled with a handwritten label “Type”, a second rectangular pink blank label, a third rectangular label "Carn. Mus. / Acc. 349", a fourth red square blank label and our lectotype designation label. It is not dissected but appears to be a male based on sculpture of the rostral apex. This name has long been considered a junior synonym of E. sordidus but with the recognition of the latter species as distinct from specimens occurring further east and north, the oldest available name for these eastern forms becomes E. curtus .

Redescription.

Body length (exclusive of head and rostrum) 1.8-2.8 mm, cuticle largely bare, variously covered with short, fine recurved seta-like scales only, although often encrusted and coated with a fine film. Pronotum with lateral margins rounded, margins constricted at about apical one-third such that apical one-third is tubulate, greatest width at about basal one-third, medially carinate or not. Elytra strongly rounded dorsally and laterally, striae distinct, punctures moderate in size and depth; all elytral intervals evenly elevated, slightly rounded, each with single row of fine recurved seta-like scales. Metaventrite medially impressed behind mesoventral cup. Abdomen with ventrite 1 with pair of obliquely arranged transversely elongate pits which are continuous medially, area around pits with inwardly directed scales. Legs with femora and tibiae at most fringed with a few erect scales especially along outer margin of tibiae, hind tibiae subequal in width throughout most of length. Aedeagus about as long as one-half length of aedeagal apodemes or slightly shorter, in lateral view slightly ventrally curved, in dorsal view with margins very gradually tapered towards apex at about apical one-quarter to one-fifth where abruptly constricted, apex produced medially as broad lobe-like extension, broadly rounded at tip. Internal sac with large distinct cruciform apical sclerite complex, with well-defined posterior bars, anterior and transverse bars not well defined.

Distribution

(Figure 7). This species is widely distributed in the eastern U.S.A. from Illinois and Pennsylvania in the north, south nearly to the Gulf Coasts of Louisiana and Mississippi. Across this range it exhibits a high degree of intraspecific genetic variation, with some surprisingly well supported subclades, especially in a group of populations from central South Carolina (Greenville and McCormick Counties). However, most of the range of the species is sparsely represented in the sequence data set, and no further subdivision appears warranted.
