Recognition. In general, O. umbellae can be distinguished readily from the other common and widespread North American species, O. salebrosus , by the character states given in the key and the table. Along the southeast shore and in the northern counties of Florida, however, male specimens can be confused with O. calcarifer and O. larvatus . In doubtful cases, O. calcarifer can be separated

reliably by genital character states. Small, abraded O. umbellae and O. larvatus may not be distinguishable at all without female specimens in the series.

Nomenclatural notes. This species usually has been identified as O. scutellumalbum (Say) in collections. Say (1831) stated in the description that the series was taken in Pennsylvania, Indiana, and Missouri, and mentioned Arkansas as provenance of a variety. He adopted the epithet from Knoch in litt. (in Melsheimer 1806) who, according to an annotation in Melsheimer’s personal copy made by his son, actually referred to Anthonomus suturalis . Say distinguished varieties A and C, but did not refer to variety B in the description. Two species of Odontocorynus from the above localities match the description. Of particular interest is the statement under variety A, ‘‘rostrum is more recti-linear towards the tip.’’ From this it may be deduced that variety A is O. umbellae and the remainder possibly O. salebrosus . The current usage of the name is that of Casey (1892), who interpreted Centrinus scutellumalbum in the sense of O. umbellae . This view was adopted by Blatchley & Leng (1916), Casey (1920), and O’Brien & Wibmer (1984). The remnants of the Say Collection do not include any C. scutellumalbum (see Mawdsley 1993). Material in American and European historic collections shows that contemporary collectors (including Say) did not

272 274 distinguish between O. umbellae and O. salebrosus . A specimen in the Harris Collection ( MCZ) identified by Say in 1834 is O. salebrosus . It was labeled as type of C. scutellumalbum by museum staff, but there is no evidence that it belonged to the original series. In the LeConte Collection ( MCZ) are five specimens without collecting data, the first three (including the labeled specimen) being O. salebrosus , the others O. umbellae . Five specimens in the Horn Collection ( MCZ) are O. umbellae . Casey’s specimens ( USNM) all are O. umbellae . The historic series #37600 at the MNHUB includes seven O. umbellae and four O. salebrosus . I have not examined the specimens of the Germar Collection, because none shows evidence of coming from Say (K. Schneider, in litt.); Germar (in Schönherr 1836: 730) mentioned Carolina, and specimens with this origin cannot by syntypes of C. scutellumalbum . Only two specimens, deposited in the Schönherr Collection, have evidence that they were syntypes. They are female, pinned and labeled the same way, with provenance Pennsylvania. According to the loan invoice, one is Germar’s nominal form; the other is Germar’s variety beta (in Schönherr 1836: 730). To accomplish stability of the name, I here designate the darker specimen as lectotype of Centrinus scutellumalbum . The paralectotype is slightly more reddish and lacks the left antenna and the right funicle.

Rhynchaenus umbellae Fabricius is an available and valid name for C. scutellumalbum . The species was catalogued under Ceutorhynchinae (e.g., Schönherr 1837, 1845; Melsheimer 1853; Gemminger & Harold 1871; Crotch 1873; Henshaw 1885; Leng 1920; O’Brien & Wibmer 1982), before Colonnelli (1993) transferred it to the Baridinae. Because the name has been used as valid after 1899, it is not a nomen oblitum. Rhynchaenus umbellae is transferred here to Odontocorynus , as O. umbellae (Fabricius) new combination, and placed in synonymy with O. scutellumalbum and 17 other species described by Casey (1920, 1922). Somewhat amazing is Casey’s (1922) record of three Odontocorynus from Santarem in Brazil, particularly as he noted that they look as if collected in Pennsylvania. They bear handwritten labels with numbers used for preliminary sorting, but no collecting data. All of them are typical O. umbellae . I found no evidence that a species of Odontocorynus , as understood here, occurs in South America.
