Fig. 1 in Hitherto undescribed interommatidial exocrine glands in Chilopoda

Fig. 1. Semi-schematic reconstruction of two different types of scutigeromorph and lithobiomorph interommatidial exocrine gland. A. A longitudinal section through one interommatidial exocrine gland present within the compound eye of Scutigera coleoptrata. B. The probably more advanced lithobiomorph type, where up to three glandular modules are fused to one single interommatidial exocrine gland (Lithobius forficatus, cut-away view). cc = canal cell, co = cornea, du = cuticular gland ductule, gc = secretory gland cell, igc = intermediary gland cell, ipc = interommatidial pigment cell (covering cell), om = ommatidium.
