Minettia plumicornis Fallén 1820  

Living larvae moderately dorsoventrally flattened, distal parts of Malpighian tubules inflated, with typical ventral loop.

Egg ( Figs 13, 14 View FIGURES 9 – 14 ). Length 0.61–0.78 mm. Robust, with number of ridges, ribs slightly indicated. Posterior tubercle prominent with marked perforations.

First instar ( Figs 77, 78 View FIGURES 77 – 80 ). Length 1.18–1.76 mm. Facial mask narrow (eight scraping cirri per row); peristomal cirri very few and robust, almost spine-like.

Cephaloskeleton ( Fig. 169 View FIGURES 168 – 173 ) robustly build. Length 0.23–0.27 mm. Mouth hooks with only two apical teeth, basal part sclerotised, dental sclerite absent. Parastomal bars strong. Subhypostomal sclerites converging.

Second instar ( Figs 79, 80 View FIGURES 77 – 80 ). Length 1.78–2.79 mm. The facial mask narrow, 11–12 scraping cirri per row, scraping cirri in first rows with simple tips; peristomal cirri robust. Labial lobe with smooth internal surface. The thoracic segments with dense rows of comb spines anteriorly. The body segments beginning with the second thoracic laterally covered by small bumps, the last body segments covered by bumps even dorsally. The posterior spiracles robust with small and simple peristigmatic tufts.

Cephaloskeleton was not acquired. Mouth hooks with two apical teeth.

Third instar ( Figs 81–86 View FIGURES 81 – 86 ). Length 2.99–5.16 mm. The external features conform to that of the second instar.

Cephaloskeleton ( Fig. 198 View FIGURES 198 – 203 ) robustly build. Length 0.51–0.54 mm. The mouth hooks converging, as large as the intermediate sclerite. The epistomal sclerite as narrow transversal and arched strip; posterior hyaline process with two sclerotised corners. The subhypostomal sclerites converging. The intermediate sclerite and the parastomal bars interconnected via strip of cuticle. The dorsal cornua broad. The ventral cornua posteriorly hyaline.
