Calymmochilus delphinus Askew in Askew & Nieves-Aldrey 2004: 32 , 35, 36. Holotype ♀, MNCN, re-examined by LF. Type locality: Spain, Granada, Calahonda. Calymmochilus delphinus ; Askew & Nieves-Aldrey 2017: 10 (distribution).

Diagnosis. Female. Macropterous. Mesosoma and head concolorous, dark brown with reduced metallic lustre ( Fig. 3 ); gaster with mostly white to hyaline Gt1, and largely yellow Gt7 (syntergum) with a brown stripe running laterally from cercus to near the apex ( Fig. 31 ), otherwise variably brown and usually with Gt2–Gt5 with a darker rim along distal margin resulting in a banded pattern. Legs and usually also scape almost uniformly yellow to yellow-brown ( Fig. 3 ). Head not conspicuously modified, convex, with lower parascrobal region passing smoothly into gena ( Fig. 32 ). Clypeus protuberant, convex, apically serrate. Scrobal depression deep, with sloping, noncarinate sides, entirely reticulate ( Fig. 32 ). Frontovertex between ocellar triangle and scrobal depression reticulate ( Fig. 32 ). Mesoscutum reticulate virtually to posterior margin. Mesoscutellum and axillae differentiated and distinct, scutellum slightly convex. Acropleuron uniformly strongly reticulate, though mesally with smaller mesh size ( Fig. 30 ). Fore wing clear except for darker base.

Male. Body brown with almost no metallic lustre ( Fig. 4 ). Head in exact dorsal view ( Fig. 75 ) 4.5–4.7× breadth of an eye measured along a transverse axis as in figure 73. Frontovertex between ocellar triangle and scrobal depression uniformly reticulate though cells delineated by only slightly raised ridges ( Fig. 74 ). Scrobal depression including scrobes smooth and shiny except for superficially sculptured outer margins ( Fig. 74 ). Funicle with first segment plus strongly reduced anellus 2.1–2.4× as long as wide ( Fig. 64 ). Mesoscutum uniformly reticulate virtually to posterior margin, with cells delineated by slightly raised ridges. Mesoscutellum reticulate (in very small specimens coriaceous-reticulate) except frenal area coriaceous ( Fig. 4 insert). Metascutellum transverse-ovoidal, with lateroventral corners abruptly sunken ( Fig. 69 ). Fore wing stigma an elongated rectangle; uncus frequently almost to fully as long as height of stigma ( Fig. 59 ).

Distribution. Previously known only from continental Spain ( Askew & Nieves-Aldrey 2004). Here newly recorded for the Canary Islands, France and Greece. Reported by Askew and Nieves-Aldrey (2017) from Canary Islands based on the record in this paper.
