Hello, In the Manual of Afrotropical Diptera (volume 1), one of the diagnostic features of Chloropids (cf. br. 11 p. 330) is vein M4 usually with characteristic kink. What is a "kink" on a vein? Could this Chloropid from Ivory Coast be a Pseudochromatopterum rileyi Deeming, 1981?  H. Dumas : Côte d'Ivoire : Man : -- : 29/09/2019 Altitude : NR - Taille : 4.2 mm Réf. : 253535  H. Dumas : Côte d'Ivoire : Man : -- : 29/09/2019 Altitude : NR - Taille : 4.2 mm Réf. : 253536 Is it a male or a female? Edited by HDumas on 19-04-2020 09:26 Greetings from Provence |

Pseudochromatopterum rileyi Deeming, 1981 (Chloropidae, Chloropinae) is the correct identification. Description in J. natural Hist. 15(5): 789-828 (on p. 799). The author of this post possesses the species from Ghana: 1 female, 13.x.1998, 2.5 km north of Hohoe, leg. Werner Barkemeyer. Altogether now 10 specimens are known 8 of them from the original description. Answer: The kink of vein M4 is typical for all world Chloropidae and marks the point where the lost anal cell (cup) touched with vein CuA2 the vein CuA1 = M3+4. In many chloropid images in diptera.info this kink is well to be seen and is partly also commented. The anal cell of Chloropidae was already lost in Eocene (Tertiary) fossils. |

Dear von Tschirnhaus, Thank you for these details. Please could you tell me from where the type serie specimens were collected? To know if Ivory Coast could be a new country record. Best wishes |
