( Figure 1 A–C)

Material examined

Holotype and two paratypes: Ecuador, Bombuscaro National Park , 4 ° 06.879S, 78 ° 08.319W, 1040 m, Podocarpus , soil litter fermentation horizon, November 2005, leg. J. Illig.

Measurements of holotype

Prodorsum: length 215, width 147, height 96.1, sensillus 91.1, setae: interlamellar 96.1, lamellar 75.9, rostral 88.5, exobothridial 15.2; notogaster: length 374, width 257, height 252, setae: c 1 81.0, h 1 75.9, ps 1 50.6, c 3 27.8, ps 3 32.9; genitoaggenital plate 119X50.6, anoadanal plate 182X37.9.

Description

Colour yellow. Integument densely dotted.

Prodorsum with a pair of long lateral carinae. Sensilli long, bacilliform, curved, covered with seven to nine cilia in distal half. Setae long, flagellate distally (especially rostral setae), interlamellar and lamellar setae erect, covered with small spines, rostral setae bent towards the end of rostrum, rough, exobothridial setae the smallest, in. ro. le. ex. Distance between rostral setae shorter than between lamellar and interlamellar setae. Mutual distance between rostral setae slightly longer than between lamellar setae.

Notogaster with rather short setae (c 1, c 1 – d 1), covered with small spines in distal half, dorsal setae longer than other setae. Setae c 1 and c 2 remote from anterior border more than c 3 setae.

Nine pairs of genital setae present, two pairs in progenital position. Two pairs of aggenital setae present, setae ag 2 longer than ag 1. Three pairs of anal and three pairs of considerably longer adanal setae present. Anal setae an 1 considerably longer than an 2 and an 3 setae. Adanal setae ad 1 and ad 2 also considerably longer than ad 3 setae.

Tarsi of legs monodactylous.

Etymology

The specific name bombuscaroensis refers to the locality Bombuscaro National Park.

Comparison

The new species is distinguishable by the following character states: presence of two pairs of lateral carinae of prodorsum, long and bacilliform sensilli, flagellate rostral setae, aggenital setae ag 2 longer than ag 1 setae and setae ad 1, ad 2, an 1 longer than setae an 2, ad 3, an 3.
