Pseudomonardia tobiasi JASCHHOF sp. n.

( Fig. 7 A-D)

Diagnosis:

This is the only PseudomonardiaPseudomonardia species in which the gonostyli bear two spines, a pointed spine apically and a plate-like, rounded spine dorsosubapically ( Fig. 7 A-B). The V-shaped gonocoxite emargination ( Fig. 7A ) is shared with P. dawnae sp. n. (see next) and P. glacialis JASCHHOF, 2003 from New Zealand, both with a single spine on the gonostylus apex.

Description:

Male. Body size: 0.9-1.1 mm. Head: Postfrons asetose. Eye bridge 2-3 ommatidia long laterally and 3-4 ommatidia dorsally. 8-12 postocular bristles. Neck of fourth antennal flagellomere clearly shorter than node; node with 1 single to double whorl of setae subbasally, 1 complete and 3-4 incomplete whorls of long sensory hairs, several hair-shaped translucent sensilla on apical half ( Fig. 7D ). Maxillary palpus 4-segmented, fourth segment longer than third.

Wing: ApicR1 = 3.0-4.0 times the length of Rs. R5 without ventral setae. Legs: Pretarsal claws with 3 teeth behind subapical swelling. Empodia as long as claws.

Terminalia: Tg9 subtrapezoid, much shorter medially than laterally ( Fig. 7A ), evenly setose dorsally, with weak pubescent lobes ventrolaterally. Gonocoxites with deep V-shaped emargination ventrally; antGA short and thick ( Fig. 7A ). Gonostylus much broader basally than apically, excavated medially, 1 thick pointed spine apically, 1 plate-like rounded spine dorsosubapically, the latter very thin and thus often hardly visible ( Fig. 7 A-B). Ejaculatory apodeme as long as tegmen, slightly widened basally, accessory gland ducts not visible ( Fig. 7C ). Tegmen largely membranous, almost as long as wide, slightly tapered towards broadly rounded apex, parameral apodemes sclerotized ( Fig. 7C ). Cerci with short setae ( Fig. 7A ).

Female and immature stages: Unknown.

Etymology:

This species is named after Tobias MALM, Ph.D. student with the Naturhistoriska Riksmuseet Stockholm , Department of Entomology , who was also a member of the 2006 expedition to Tasmania .
