Pseudomonardia dawnae JASCHHOF sp. n.

( Fig. 8 A-D)

Diagnosis:

Only Pseudomonardia dawnaedawnae and P. pallida JASCHHOF, 2003 from New Zealand have 3-segmented maxillary palpi. The gonostyli of P. dawnaedawnae bear an apical spine, whereas the gonostyli of P. pallidapallida are spineless.

Description:

Male. Body size: 1.0- 1.1 mm. Head: Postfrons asetose. Eye bridge 1-2 ommatidia long laterally and 3-4 ommatidia dorsally. 5-8 postocular bristles. Neck of fourth antennal flagellomere longer than node; node with 1 single whorl of setae subbasally, 1 complete and 2 incomplete whorls of long sensory hairs, several hair-shaped translucent sensilla on apical half ( Fig. 8D ). Maxillary palpus 3-segmented, third segment longer than second.

Wing: ApicR1 = 2.0-3.0 times the length of Rs. R5 without ventral setae. Legs: Pretarsal claws with 3 fine teeth behind subapical swelling. Empodia as long as claws.

Terminalia: Tg9 subtrapezoid, much shorter medially than laterally ( Fig. 8B ), evenly setose dorsally, with weak pubescent lobes ventrolaterally. Gonocoxites with deep V-shaped emargination ventrally; antGA vestigial ( Fig. 8B ). Gonostylus small, tapered towards apex, 1 flat rounded spine apically accompanied by 2 short stiff subapical bristles, another such bristle on outer margin ( Fig. 8B ). Ejaculatory apodeme as long as tegmen, accessory gland ducts distinctive ( Fig. 8A ). Tegmen largely membranous, about as long as wide, slightly tapered towards rounded apex, parameral apodemes broad, sclerotized ( Fig. 8A ). Cerci with short setae ( Fig. 8B ).

Female. Body size: 1.1 mm. Head: Antenna with 9 flagellomeres, apical flagellomere constricted, fourth flagellomere with very short neck, node with 1 whorl of hair-shaped translucent sensilla basally, 1 whorl of setae subbasally, numerous hair-shaped translucent sensilla scattered on distal half ( Fig. 8C ). First segment of maxillary palpus swollen.

Legs: Fifth tarsomeres twice a long as fourth tarsomeres, with sole of short stiff blunt-tipped setae.

Terminalia: 2 small globular sclerotized spermathecae. Basicercus and disticercus subequal in length.

Immature stages: Unknown.

Etymology:

This species is named after Dawn WILIAMS, Naturhistoriska Riksmuseet Stockholm, Research Division Directorate, who joined the 2006 expedition team to Tasmania.
