(17) Psychomyia pusilla; (18) Metalype fragilis (larva from English population); (19) Paduniella vandeli. The arrows indicate the diagonal dark thickening. For procoxopleurite and procoxa, see figure 26; (20) Tinodes waeneri, no diagonal dark thickening; ventrolateral extensions (ve) of the pronotum are present. (21) Pad. vandeli, the arrows indicate the distal extremities of the diagonal dark thickenings of Fig 19.";

For Psy. pusilla and M. fragilis, the two arrows indicate the prosternal sclerites, for M. fragilis, a cuticular fold overlaps partially the lateral part of the prosternal sclerite; for T. waeneri, the arrow indicates the ventrolateral extension (ve) of the pronotum; the yellow dotted line indicates the trace of the prosternal sclerite attached to the ventrolateralextensions of thepronotum; for Pad. vandeli, the yellow dotted line underlines the trace of the colourless roll of membrane.";
