“…megatheca by the dorsal apotome wider than long, AM-1-T minute seta, AM-2-T long, thin seta with associate pore, CL-1-T and CL-2-T campaniform sensilla, the respiratory organ with 11-12 apical pores, D-2-T minute seta, D-5-I absent, L-1-I minute seta, L-2-I short seta, L-3-I long, thin seta, D-3-IV, D-4-IV and D-5-IV minute setae, D-7-IV long, thin seta, V-5-IV and V-6-IV campaniform sensilla, tubercles of segment 4 rounded and distal processes of segment 9 slightly wider than long with short tips posteriorly directed. Both species share a medium-sized respiratory organ and tips of segment 9 triangular, short and pointed, typical of ceratopogonids that live in shallow and clean waters (Cazorla et al, 2012).…”
