Fig. 1. Compound eye morphology and ommatidial facet variation in T. minor. (A) Compound eyes projecting slightly beyond the head capsule, exhibiting bilateral symmetry. (B) SEM overview of oval-shaped eye; sparse ommatrichia concentrated mid-eye (a: anterior, p: posterior, v: ventral, d: dorsal). (C) SEM of dorsal region detailing quadrilateral facets (salmon) with pentagonal facets (light yellow) at the periphery. (D) SEM showing ommatidial facet transition from central hexagonals (steel blue) to ventral rounded facets (light cyan). (E) SEM detailing ommatrichial fine morphology. ANT, antennae; CE, compound eye; HOF, hexagonal ommatidial facets; POF, pentagonal ommatidial facets; QOF, quadrilateral ommatidial facets; ROF, round ommatidial facets. Scale bars: A, B = 100 μm; C, D = 20 μm; E = 2 μm.
