Nice work! It could be indeed H. macrura, but I like to rule out H. caledonica....or not. I contacted Ackland about it, so I have to wait for his response.... Johanna |

Coming back to your H. macrura. Also Michael thinks this could be indeed H. macrura (Schnabl in Schnabl & Dziedzicki, 1911) , but it would be nice if you could send me one (or two) specimen, so I can look at the shape of the gonites and phallus ….and other characters to be 100% sure! Nice find!! Johanna (you can send me a pm, my emailadress is present under my profile) |
