Nothrus cotopaxiensis View in CoL n. sp.

( Figures 1–8 View Figures 1–2 View Figures 3–8 , 67–74 View Figure 67 View Figure 68 View Figure 69 View Figure 70 View Figure 71 View Figure 72 View Figure 73 View Figure 74 )

Larva ( Figures 1–2 View Figures 1–2 )

Body length: 365 mm, body width: 160 mm; colour: white.

Surface of prodorsum with round pits. Rostrum with median incision. Setae ro small, phylliform and frayed, bent, set on tubercles. Setae le similar to ro, set on apophyses. Setiform setae in shorter than le. Sensilli setiform, third as long as in. Setae ex setiform, half as long as in.

Notogaster narrowed posteriorly. Two pairs of elongated folds of thickened chitin run from setae c 1 – c 2 to f 1. Surface of plate covered with distinct, large, round pits; with 12 pairs of frayed and phylliform setae. Setae c 2 as long as in, placed closer to c 1 than to c 3. Setae h 1 longest, as long as distance between them. Oval opening of opisthosomal gland (gla) situated close to seta f 2.

Pairs of epimeres medially separated. Epimeral setation: 3-1-3 (one seta extra on I and III epimeres). Genital, aggenital and adanal plates, and anal setae lacking.

All legs monodactylous (setation not studied).

Adult ( Figures 3–8 View Figures 3–8 , 67 – 74 View Figure 67 View Figure 68 View Figure 69 View Figure 70 View Figure 71 View Figure 72 View Figure 73 View Figure 74 )

Body length: 830–900 mm (holotype: 850 mm), body width: 420–450 mm (holotype: 420 mm); colour: brown.

Prodorsal surface with round pits. Setae le three times longer than ro. Setae in frayed, as long as le. Sensilli thin, distally notched, almost twice longer as distance between their bases. Setae ex setiform and short.

Notogaster broadest at level of setae e 2. Two pairs of elongated folds of thickened chitin run from setae c 1 – c 2 to e 2. Surface of plate between folds covered with distinct, large, round pits; lateral surface with small pits, posterior part with sparse pits. With 16 pairs of frayed and phylliform setae, thinner than in larva. Setae c 2 placed closer to setae c 1 than to c 3. Setae h 2 longest, as long as distance between their bases and as sensilli. Oval opening of opisthosomal gland (gla) situated close to seta f 2.

Pairs of epimeres medially separated. Epimeral setation: 7-4-6-(4,5). Genital plates with nine pairs of short setae; two pairs of anal and three pairs of adanal setae. Aggenital setae lacking.

All legs tridactylous (setation not studied).
