Original Description:
Geographic Distribution:
New Providence and Adjacent Islands, Bahama Islands
Type Locality:
Old fields off Kemp?s Road, East Nassau, [New Providence Island, Bahamas]
[25° 2' N, -77° 17' W]



Type Material:
Lectotype, MCZ 76336

The unintended description of Strophiops repetita  is based on the illustration of a single specimen (figure 89).  It is likely that this was one of  1,052 specimens mentioned in the intended description of this taxon (Maynard and Clapp in Maynard, 1921b:149) that were available to Maynard at the time, and are thus part of the type series [Article 72.4.1.1 (ICZN, 1999:76)].  Strophiops repetita  is therefore based on 1,052 syntypes.  No specimen labeled as the  "Holotype" of Strophiops repetita was catalogued at the MCZ.   MCZ 76336 contained 198 specimens and was labeled "Paratypes".   A single specimen was sequestered in a vial and labeled "figured".  This specimen closely approximates both the illustration in figure 89 and the measurements in the intended description.  Also present was a label in Maynard's handwriting  referring to "Fig 89" and "Plate 45 figs 5-6".  This label indicates that the sequestered  specimen is the specimen in figure 89, and also the specimen that Maynard regarded as the "type" because he planned to illustrate it as part of the intended taxon description.  This specimen, which retains the number MCZ 76336 is has been designated as the lectotype of Strophiops repetita Maynard and Clapp in Maynard, 1920 by Harasewych et al. (2007:461, fig. 138)  in order to provide an objective standard of reference for this species-group taxon that is consistent with Maynard's original concept of it.  The remaining 197 specimens were recatalogued  as MCZ 357003, and are among the remaining 1,051 specimens that become paralectotypes.

Remarks:

The binomen S. repitita first appeared as a nomen nudum (Maynard, 1919b:36).  The name was used as S. repetita (Maynard, 1920c:96, fig. 89) prior to the intended taxon description as an example of Maynard's "Law of Specific Reincarnation."  The association of a new species group name with an illustration of the taxon being named prior to 1931 makes the name Strophiops repetita Maynard and Clapp in Maynard, 1920 available (Article 12.2.7, ICZN, 1999:17) prior to the intended description of this species (Maynard and Clapp in Maynard, 1921b:149).  The caption to figure 89 reads "S. repetita M & C.", establishing the authorship as Maynard and Clapp in Maynard, 1920.

 

The spelling Strophiops repitita appeared only as a nomen nudum (Maynard, 1919b:36).  Both the unintended and the intended taxon descriptions used the spelling S. repetita.  The sales catalog (Maynard, 1924b?:[4]) used the spelling repitita, but its supplement (Maynard, 1924c:6) listed S. repetita as nearly extinct (only three specimens) in 1924, due to burning of vegetation prior to cultivation.  Based on the preponderance of usage, it would seem that Maynard intended the name of this taxon to be repetita.   This is the only spelling to appear in both the unintended and intended taxon descriptions as well as the captions to the accompanying illustrations, and there is no clear evidence to suggest an alternative spelling within the original publication itself [Article 32.5.1 (ICZN, 1999:39)].

Gould and Woodruff (1986:477) regarded this taxon to be a synonym of Cerion gubernatorium (Crosse, 1869).
