Type locality: "10.6km N Calo Rojo on the Alcoa road (2.6km N Pedernales-Oviedo road), Pedernales Province, Dominican Republic, elevation 80 m"
|Types||Holotype: USNM 317892|
|Diagnosis||Diagnosis: A small, short, but acute-snouted species of Sphaerodactylus (18-22 mm SVL,snout-vent length) with large, flattened, keeled, imbricate dorsal body scales and unusually large cobblelike (broad, rounded, and raised) snout scales (snout averages 36% head length); with only two toe pad bracket scales; a four-lined head pattern, with the two postocular lines extending onto the body as dorsolateral and midflank stripes (indistinct in most specimens); and with minute prescapular ocelli in line with the head stripes. Sphaerodactylus plummeri is unique in several respects: it has the lowest dorsal and midbody scale counts of any Hispaniolan species (among the lowest of any species); the snout scales are the largest (with the exception of S. elasmorhynchus); it has only two toe pad bracket scales (only one other species of Sphaerodactylusthat we have examined has fewer than three); and females undergo ontogenetic head pattern modification in which the striped pattern becomes broken into spots. Sphaerodactylus streptophorus (Fig. 1B) is a small, dark or dull-colored species and superficially resembles S. plummeri; however, it is larger than S. plummeriwith a maximum SVL of 26 mm. The two differ in details of coloration: S. s. streptophorus,the Barahona Peninsula subspecies, has a pale transverse collar across the neck, no dorsolateral lines, and much smaller body scales (midbody scales 41-62: Thomas and Schwartz, 1983); it also has smaller snout scales and three toe pad bracket scales. A larger species, S. armstrongi (Fig. 1C), occurs in the upper elevations of the Sierra de Baoruco and Massif de la Selle (it occurs at higher elevations on the Alcoa road). Although it is dark like S. plummeri,S. armstrongi usually has Y or V-shaped markings on the head, various ocelli on the body, and has a much greater number of midbody scales (49-75; Thomas and Schwartz, 1983). Sphaerodactylusrandi also is a larger species with smaller scales; its basic pattern involves the trilineate head pattern (as in difficilis),a dark scapular patch, and a pair of ocelli. We compare S. plummeri with these species because they occur in the area and might be confused with plummeri on superficial examination (from Thomas & Hedges 1992: 291).|
|Comment||Its combination of small body size and very large, flattened, keeled dorsal scales distinguish it from other species in the genus.|
Abundance: only known from its original description (Meiri et al. 2017).
|Etymology||Named after one of the collectors, Nicholas Plummer.|
