11. Subgenus PAPUATIPULA Alexander
Tipula (Papuatipula) ALEXANDER, Proc. Linn. Soc. New South Wales
59 (1934) in press.
Type.-Tipula nove-britannicxe Alexander. (Australasian.)
Antennae 13-segmented; flagellar segments with verticils that
greatly exceed the segments in length. Frontal prolongation of
head elongate, subequal to remainder of head; nasus distinct.
Tibial spur formula 1-2-2; spurs long and conspicuous.
Squama naked; trichia of veins beyond cord unusually sparse
and scattered there being a loose series on R4+5 and M1. Venation: R1+2 entirely atrophied or represented only by a short
basal spur; Rs unusually short but not transverse, approximately
two-thirds m-cu; R2+3 very long and straight, exceeding twice
m-cu; vein Rs elongate, lying unusually close to costal border of
wing, subequal in length to R2+3; cell 1st M2 elongate, its inner
end strongly pointed; cell M1 deep; m-cu uniting with M3+4 some
distance before its fork, usually at near midlength.
Male hypopygium with the tergite separated from the sternite
by a suture, fused only at extreme cephalic portion; basistyle
fused with sternite. Tergite notched medially. Outer dististyle armed with a spinous point. Eighth sternite unarmed.
This subgenus has proved to be the most characteristic one
in New Guinea and its satellite islands and will probably be
found to be very rich in number of species when the region
becomes better known. It is most nearly allied to Acutipula
Alexander, Tipulodina Enderlein, and Indotipula Edwards, especially the first of these. It is distinguished by the venation,
naked squama, and fundamentals of the male hypopygium, as the
unfused tergite and sternite, notched tergite, and armed outer
dististyle.
