Diagnosis. Face without faint subantennal sulcus ventral to each torulus and without a pit medially next to each torulus (Figs 98, 103); toruli separated by well over height of torulus from transverse trabecula; propleura abutting each other anterior to prosternum; fore wing with (Figs 100, 106) or without dark bands, with venation less than 0.2× wing length (Figs 100, 106) and marginal vein absent (105); propodeum with submedian carinae, either more widely separated from each other anteriorly (Fig. 101) or the carinae sometimes united posteriorly into a single carina, or only a single median carina present, sometimes only posteriorly (Fig. 107) or apparently entirely absent; propodeal seta on posteriorly facing tubercle near posterior margin of propodeum (Figs 101, 107, 108); petiole apparently attached posteriorly to gt 1 (Figs 102, 108). Remarks. Cremnomymar belongs to the Polynema group of genera. Cremnomymar species occur mainly on the Juan Fernández Islands. Those on Robinson Crusoe Islands (Masatierra Island) have diversified into very different looking species — a Hawaiian- Drososphila -like radiation though with far fewer species or, more appropriate for the Neotropical region, a Darwin’s finches radiation, writ small. The only feature uniting the Cremnomymar species is the propodeal seta on a distinct tubercle. The propodeal carina(e) character is variable. Head shape, body colour, wing length and shape are also diverse so it is understandable why Ogloblin classified the species in four genera and Fidalgo proposed another genus (Parapolynema) for species on mainland South America. Until a better understanding of the Juan Fernandez Islands Cremnomymar species is obtained we prefer not to treat the synonyms listed above as subgenera, partly also because Ogloblin based two of his genera on males, one on females and one (Cremnomymar itself) on both sexes.
