Pseudomonardia dorani JASCHHOF sp. n.

( Fig. 5 A-C)

Diagnosis:

This species belongs to the informal group of pseudomonardias in which the gonocoxite emargination is U-shaped and the apical gonostylus spine is present (see JASCHHOF & JASCHHOF 2003: 115 f.). There are 3 such species in New Zealand ( P. communis , P. parva JASCHHOF, 2003 , and P. elongata JASCHHOF, 2003 ) and 2 in Tasmania ( P. dorani , P. niklasi sp. n.). Among these, P. dorani is the only species in which the gonostyli are elongate and slender, and the gonostylus spine is situated truly apically ( Fig. 5A ).

Description:

Male. Body size: 0.9-1.1 mm. Head: Postfrons asetose. Eye bridge 2-4 ommatidia long. 4-8 postocular bristles. Neck of fourth antennal flagellomere shorter than node; node with 1 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. 5B ). Maxillary palpus 4-segmented, long and slender, fourth segment usually much longer than third.

Wing: ApicR1 = 3.5-4.0 times the length of Rs. CuA2 very short. R5 without ventral setae. Legs: Pretarsal claws with 3 fine teeth behind subapical swelling. Empodia 1/3 as long as claws.

Terminalia: Tg9 short, subtrapezoid, evenly setose ( Fig. 5A ). Gonocoxites with broad U-shaped, moderately deep emargination, below emargination a subtriangular membranous portion without setae; antGA well developed, pointing anterolaterally ( Fig. 5A ). Gonostylus slender, tapered towards apex, apical portion curved inwards, 1 slender pointed spine apically, 1 short stiff subapical bristle dorsally, another such bristle on outer margin ( Fig. 5A ). Ejaculatory apodeme thin, slightly shorter than tegmen ( Fig. 5C ). Aedeagus head fully membranous, accessory gland ducts distinct, far apart from one another ( Fig. 5C ). Tegmen largely membranous, particularly weak and instable on apical third, usually broadly rounded, lateral margins with small rounded projections, parameral apodemes slightly sclerotized ( Fig. 5C ). Cerci with short setae ( Fig. 5A ). St10 present as very weak membranous double lobe with few microtrichia, not always visible (not figured).

Female and immature stages: Unknown.
