Habitus
. BL
2.4 mm
, BL/BW ~1.7, elongate oval, similar to
N. thylacinus
.
Male
. Segments 8 (Figs. 121, 122) and 9 (Fig. 123) as described for the genus. Penis (Fig. 123) parallel-sided, with rounded pala. The short trigonium inserts near the basal third. The contour of the trigonium resembles an inverted heart, its sides are thickened, the bulges bear huge teeth along the medial edge. The straight parameroid is much longer than the trigonium, the long bare apex bears externally a toothed sclerotized lobe pointing cephalad. In dorsoventral view the tips of the parameroid and of the paramere overlap. The paramere is short, slender and heavily toothed along the outside and distally. The tegmen is a thin sclerite arch connecting the parameres.
Female
. Unknown.
Etymology
. The trigonium reminded me of a strongly toothed lower jaw of a predator. This suggested the name:
Sarcophilus
,
the Tasmanian Devil, the largest extant carnivore in Tasmania.
