Lagopoma lagopoma Bartsch, 1946

Figures 4 Y–CC, 8E

Type locality. USNM 356198, holotype.

Type locality. Laguna, 4 miles N of Samaná, Samaná Province, Dominican Republic.

Other material examined. UF 216120, El Valle, Samaná Province, Dominican Republic; UF 216201, El Valle, Samaná Province, Dominican Republic; UF 236121, El Valle, Samaná Province, Dominican Republic; GTW 10081a, El Valle, Samaná Province, Dominican Republic.

Distribution and habitat. Found along the base of the high limestone cliffs in the region of El Valle in the Sierra de Samaná of the Cordillera Septentrional, possibly along the south-western edge of this outcrop as well. This species is found in association with A. abbotti and A. sosuaensis .

Comparison with other species. This species is characterized by the peculiarly folded auricle and notched outer lip. Abbottella sanchezi ( Figure 4 J–N) occasionally has a similar auricle but lacks the notch. However, it is questionable whether these minor features of the outer lip deserve a genus-level name.
