Pseudomonardia niklasi JASCHHOF sp. n.

( Fig. 6 A-C)

Diagnosis:

The following character states in combination are diagnostic. The gonostyli have a strongly convex outer margin and a fine apical spine; the gonocoxite emargination is shallow and evenly rounded; and the tegmen apex is slightly constricted ( Fig. 6A ).

Description:

Male. Body size: 0.8-0.9 mm. Head: Postfrons asetose. Eye bridge 3-4 ommatidia long. 5-6 postocular bristles. Neck of fourth antennal flagellomere shorter than node; node with 1 single to double whorl of setae subbasally, 1 complete and 3 incomplete whorls of long sensory hairs, several hair-shaped translucent sensilla on apical half ( Fig. 6C ). Maxillary palpus 4-segmented, long and slender, fourth segment much longer than third.

Wing: ApicR1 = 2.5-3.0 times the length of Rs. R5 without ventral setae. Legs: Pretarsal claws with 3 fine teeth behind subapical swelling. Empodia reduced to a few hairs.

Terminalia: Tg9 subtrapezoid, evenly setose ( Fig. 6A ). Gonocoxites with shallow, evenly rounded, U-shaped emargination ventrally; antGA short and thick ( Fig. 6A ). Gonostylus thick, outer margin strongly convex, 1 fine pointed spine apically accompanied by 1-2 short stiff subapical bristles ( Fig. 6A ). Ejaculatory apodeme thin, slightly longer than tegmen ( Fig. 6B ). Accessory gland ducts distinct ( Fig. 6B ). Tegmen membranous, as long as wide, slightly constricted apically, parameral apodemes delicate, sclerotized ( Fig. 6B ). Cerci with short setae ( Fig. 6A ).

Female and immature stages. Unknown.

Etymology:

This species is named after Niklas JÖNSSON of Naturhistoriska Riksmuseet Stockholm, Department of Entomology, who was one of the participants of the Swedish entomological expedition to Tasmania in 2006. Many of the specimens studied here have been collected by his expedition team.
