Minettia flaviventris   (Costa 1844)

Egg. Preparation for SEM was not successful.

First instar. Length 1.25–1.84 mm. The first row of scraping cirri poorly differentiated. Number of scraping cirri per row very small (8 in the first row). The thoracic segments with broad belts of comb spines anteriorly.

Cephaloskeleton ( Fig. 167 View FIGURES 162 – 167 ). Length 0.23–0.24 mm. The basal part of the mouth hooks coalescing into a single plate with two medial perforations, tips ending in two teeth. The parastomal bars very strong.

Second instar. Length 2.48–3.61 mm. Scraping cirri in six rows, 6–7 cirri per row, tips of cirri simple in first rows. The first thoracic segment with wide belt of comb spines dorsally.

Cephaloskeleton ( Fig. 182 View FIGURES 177 – 182 ). Length 0.32–0.34 mm. Mouth hooks converging, two apical teeth; dental sclerite unusually large. Epistomal sclerite narrow and arched from dorsal view; posterior hyaline plate rectangular. Subhypostomal sclerites converging, tips converging. Ligulate sclerites arched from ventral view. Rami strong, straight. Parastomal bars strong, connected to the intermediate sclerite via thin sclerotised cuticle. Dorsal bridge trapezoid. Distal part of ventral cornua hyaline, dorsal margin concave. Cibarium hyaline.

Third instar. Length 3.1–5.95 mm. Preparation for SEM was not successful.

Cephaloskeleton ( Fig. 197 View FIGURES 192 – 197 ). Length 0.76 mm (n= 1). Mouth hooks strongly converging, tips parallel. Intermediate sclerite strong; ventral bridge shallow from lateral view. Epistomal sclerite narrow and arched from dorsal view, posterior hyaline process with two slightly sclerotised corners. Ligulate and subhypostomal sclerites stalked, converging. Dorsal bridge trapezoid, as long as broad. Dorsal cornua as broad as ventral cornua from lateral view, distal third of ventral cornua only slightly sclerotised, concave. Cibarium pigmented, anterior edge with sclerotised band.
