Sarcophaga metopina Villeneuve, 1908: 124 View in CoL .

Type material examined. Lectotype 3, herewith designated to fix unambiguously the identity of the nominal species and thus promote nomenclatural stability: La Palma / 47514. IV. // [on underside of white label] Sammlung / Dr. Th. Becker // Type // metopina / typ. n. sp. // Zool. Mus. / Berlin // [red label] LECTOTYPE 3 / Sarcophaga / metopina / Villeneuve, 1908 /des. D. Whitmore 2010 ( ZMHB) [ lectotype in good condition, with terminalia partly pulled out of abdomen]. Paralectotypes: 1 3: La Palma [Canary Is.], 47514. IV. ( ZMHB); 1 3: La Palma, 47520. IV. ( ZMHB) [both paralectotypes carry the original Villeneuve label “ metopina typ. n. sp.” and are conspecific with lectotype; one with terminalia dissected and placed in glycerin in a microvial pinned beneath the source specimen].

Remarks. Villeneuve (1908) described Sarcophaga metopina on an unspecified number of males and females from “La Palma” (Canary Is.), without designating a holotype. The three males found in T. Becker’s collection at ZMHB are considered as representing part of the type series. The lectotype was selected for its overall better condition.

Sarcophaga ( Heteronychia) metopina is a valid species, endemic of La Palma (Canary Is.) ( cf. Báez & García 2004), and characterized by its small size (ca. 3.5–5.5mm) and the pattern of abdominal microtrichosity, reminiscent of that of the miltogrammine genus Metopia Meigen ( Diptera , Sarcophagidae ).
