Hintelmannomyia aestimata JASCHHOF sp. n.

( Fig. 9 A-D)

Description:

Male. Body size: 1.1 and 1.5 mm. Head: Eye bridge (2-)3-4 ommatidia long. 6 and 14, respectively, postocular bristles. Antennal flagellomeres elongate. Neck of fourth antennal flagellomere shorter than node; node with 1 double whorl of moderately long setae subbasally, 1 complete and 3-4 incomplete whorls of long sensory hairs, several hair-shaped translucent sensilla on apical half ( Fig. 9B ). First and second segments of maxillary palpus with hair-shaped translucent sensilla, first segment somewhat swollen, fourth segment much longer than third.

Thorax:

Scutum densely covered with scales and lateral setae. Wing: ApicR1 = 4.5 times the length of Rs. Legs: Distal arm of pretarsal claws with 4 fine teeth behind subapical swelling. Empodia 1/3 as long as claws.

Preabdomen: Terga 2-4 with large membranous portions anteromedially, sclerotized elsewhere. Terminalia: Tg9 evenly sparsely setose, on apical margin apparently with small, rounded medial lobe ( Fig. 9A ). Gonocoxites densely covered with scales and setae ventrally except for small asetose portion apicocentrally, ventroapical margin membranous medially, very slightly emarginated, slightly bulged on both sides of emargination; antGA short and narrow ( Fig. 9C ). Gonostylus with setae of various sizes, 1 large flat bilobed spine apically, outer margin convex ( Fig. 9C ). Ejaculatory apodeme poorly sclerotized, shorter than tegmen ( Fig. 9D ). Tegmen small, tapered towards narrowly rounded apex, parameral apodemes sclerotized ( Fig. 9D ). Tegmen apex wrapped by cerci, latter with short setae ( Fig. 9C ).

Variation:

The paratype specimen is smaller in size, has only 11 flagellomeres on one of the antennae, a shorter eye bridge, much fewer postocular bristles, and narrower wings. It is obviously an atrophied individual that might have developed under suboptimal conditions. Such individuals are not unusual among Micromyinae .

Etymology:

The name is Latin, meaning esteemed.

Types:

Holotype: Male, Australia, Tasmania, Warra LTER site, Manuka Road , 14 April 2000, Malaise sample FT28646, R. BASHFORD (in AMS) . Paratype: 1 male, Tasmania, Southwest National Park, Wedge Creek , 330 m, 21 Feb.-1 March 2006, by Malaise trap, N. JÖNSSON, T . MALM & D. WILLIAMS (in NHRS).
