1. Located on the venter. For legs this means that these are considered as if they were in the position as given in the illustration. So, even if a leg is pointing upwards in a specimen, one should image that the leg was positioned in a horizontal plane, perpendicular to the body axis.
2. Located in a more position towards the venter. For example, a seta can be located ventral to another seta.
Fortunately the leg flexes (bends) in the dorsoventral plane so the legs dorsum and ventrum are easily identified. The periphery
(outside) of a transverse section is then divided into eight imaginary parts, which (looking down the leg towards the body read in the direction of a clock)
dorsal
postero-dorsal
posterior
postero-ventral
ventral
antero-ventral
anterior
antero-dorsal
I have just received the very sad news that Peter Chandler has died after a fall at home yesterday. I have no other details at the moment. We shall miss him terribly.
Anyone have scans of the Genus Semaranga in:

2) Andersson, H. (1977 Taxonomic and Phylogenetic studies on Chloropid
Dr Michael von Tschirnhaus, a leading expert on Chloropidae and Agromyzidae, died on 16 September 2025 at the age of 86. He will be greatly missed by the international community. R.I.P.
Anyone has the scan of "Harkness, R. D.; Ismay, J. W. 1976: A new species of Trachysiphonella (Dipt., Chloropidae) from Greece, associated with an ant Cataglyphis bicolor (F.) (Hym., Formicidae)
