Holotype female ( USNM ), ex E. campestris , JAMAICA : Marshall's Pen, Mandeville, Feb 1982 , R.C. Dalgleish. Paratypes ( USNM ): 9 females , 9 males , same data as holotype . Remarks. This species is easily distinguished from others of the group by the female with the large posteriorly rounded metanotum bearing at least 18 marginal setae and the unusually short postspiracular setae on tergite VII. Both sexes have only five to seven anterior setae on sternite II, including one to three longer medioanterior setae. The male is further recognized by the numbers of abdominal tergal and sternal setae and its small dimensions.
