FIGURE 8. Sepedonella nana. A–E, thoracic sensilla. A in Biology of the Afrotropical Sepedonella nana (Diptera: Sciomyzidae), whose larvae feed only on freshwater Aulophorus furcatus (Oligochaeta: Naididae)

FIGURE 8. Sepedonella nana. A–E, thoracic sensilla. A, distribution on one hemi-segment of the 1–11 sensilla. B, coeloconicum sensillum (n°4). C, ampulaceum sensillum (n°1) and Keilin organ (n°2). D, chaeticum (n°8) and coeloconicum (n°9) sensilla. E, pair of the dorsal chaeticum sensilla (n°11). F, schematic distribution of the 1–11 sensilla on each hemi-abdominal segment according to three distinct abdominal portions, ab1-ab6, ab7 and ab8. bt1-bt3, dorsal transversal bands 1–3; lt1-lt3, lateral tubercles 1–3; vt1-vt3, ventral tubercles 1–3. Sensillum:, chaeticum type; *, coeloconicum type; **, flower type. Dotted arrows show hypothesis concordance between tubercles and sensilla on abdominal segment 7 and on different parts of abdominal segment 8.
