Figs. 1 —2: Myrsidea eurocephali n. sp., thorax and abdomen of male (1) and female (2). Scale = mm. All drawings by S. Lankhorst. index — (x = ± ; V = ). Clypeal margin usually smoothly rounded. Anterolateral margins moderately swollen backwards. Hypopharynx fully developed. Preocular seta 10 (see Th. Clay 1966, 1969) with 54—65 fi of length in the female (n = 4; x = ± ; V = ) and 77 p in the male (n = 2), and seta 11 repectively with 92-107 fx (x = ± ; V = ) and 88-92 fx (x = 90 ± ; V = ); ratio 10/11 in the female (x = ± ; V = ) and in the male (x = ± ; V = ). Guiar plate light brown, with the anterior transversal arms slightly diverging backwards, converging anterior- ly to the subgenal sutures and surrounding the lighter, large oval, sitophoral area. Postoccipital suture very narrow, brown, without anterior prolongations. Temples not broad, moderately bent backwards. Thorax with the pronotum developed, mainly in the female; width — mm (n = 2; x = ± ; V = ) in the female and mm (n = 3; x = ± ; V = ) in the male, with 2—3 short anterolateral setae and 3 + 3 long setae on the posterior margin. Metanotum greatly developed, large and wide, in the female with mm of breadth (n = 2; x = ± ; V = ), having the anterior margin straight, the lateral subconcavous, the posterior sub- convex, with 11—13 (x = 12 ± 1; V = ) long, posterior and 2 very short posterolateral setae, and the postero-outer angles rounded, with 1 very long seta; in.
