Lonchaea  

Description Male (holotype) Eyes bare, frons with rather numerous long black bristles, the
longest being half as long as the orbital bristle, orbital plates bare, ocellar triangle with several
long black hairs, more than half as long as ocellar bristles Jowls with a single row of about six
hairs along mouth edge Palpi black haired with two stronger bristles at the tip more than the
width of the palp Face with a distinct median keel Antennae with segment three 2 5 times as
long as wide and entirely black, rather concave on the dorsal surface and rounded at the tip,
covered m mmute white hairs, segment two with numerous short black bristles over the surface
Arista almost 1 5 times as long as antennal segment three, finely setulose, rather yellowish at the
base
Thorax with one propleural and one stigmatical bristle, both rather long, as long as bristle
on katepistemum No hairs posterior to the single strong bristle on katepistemum Hairs on disc
of thorax black and rather long, more than half as long as the notopleural bristles No hairs in the
notopleural depression Presternum bare Scutellum bare on the disc No hairs apparent
between apical scutellar bristles but two on each side between the apical and lateral bristles No
hairs on scutellar margin anterior to lateral bristles Anepimeron bare, anepistemum with 4-6
strong hairs posteriorly, 4 anteriorly Squamae with a dark fringe Stigmal section of wing rather
short, only about one and a half times as long as crossvein r-m Abdominal stemite 1 bare, others
setulose
Legs with metatarsus, all of tarsomere 2 and base of tarsomere 3 yellow, on all except
ventral surface covered m short black hairs Antenor and mid femora rather strongly bristled
posteroventrally, bristles longer than the width of the femora
Male terminalia Epandnum (Fig 1) wider than high, cerci relatively large with long hairs on the
rounded tip Surstylus extending as a rounded process beyond edge of epandnum, this process
covered in small curved black spines Aedeagus two segmented, apical section rather short and
bulbous (Fig 2) Female In main characters similar to male, basal third of arista yellow, hairs on frons below
orbital bristle all rather short, only about one third length of orbital bristle Antennal segment
three almost three times as long as wide, parallel sided with rounded tip, entirely black Coxae
with long spine at lower, outer angle, this spine as long as half the depth of the coxae,
presternum bare Front femora with about ten strong hairs posteriorly, these hairs as long as the
width of the femur, four strong bristles posteroventrally, mid femora with fringe of strong hairs
anteriorly and posteriorly all about as long as width of femora, hind femora with only a row of
shorter hairs anteroventrally Middle tibiae with a rather blunt spine at tip ventrally, this about
as long as tarsal segment two Metatarsus, second and third tarsomeres of tarsi yellow, hmd tarsi
with golden hairs ventrally on metatarsus and second tarsomere Wings with all veins whitish
yellow except the costa Two short hairs between apical bristles on scutellum, two pairs on each
side between apical and lateral bristles, these hairs less than half the length of the mam scutellar
bristles, no hairs anterior of lateral bristles No hairs posterior to the single strong bristle on
katepistemum
Ovipositor Apical segment long, three times as long as wide, connected to stemite and tergite 9
by a short section of connective tissue, stemite 9 with four rather long hairs at apex, these much
longer than hairs along length of stemite (Figs 3 and 4) Apical section dorsally with two long
basal hairs, these as long as apical segment, shorter pairs one third and two thirds of the way
along dorsal length, apical dorsal pair about half length of segment, two shorter pairs at apex
Ventrally one longer apical pair, almost as long as segment, two shorter pairs about half as long
as apical pair situated on ventral surface All these hairs yellowish

Lonchaea cornigera n. sp.

MALE. As described for L. arrogata n. sp., except for following characters of the genitalia: cerci long and rather narrow, as in impressifrons; neck-like region at base of cerci longer, thinner, and narrower than in impressifrons. Epandrium very similar in side view to that of viriosa. Surstyli of same general plan as in viriosa, but posteroventral blade-like projections narrower and many times longer; in side and ventral views resembling the horns of an antelope; each with a strong mesally directed tooth at anteroventral margin as in viriosa; 2 internal teeth on each side of mid line smaller than in viriosa. Aedeagus very similar to that of viriosa, but apical bulb larger. Two lobes arising on anterior margin of hypandrium and projecting on each side of aedeagus as in continentalis. Anterior gonopophyses similar to those of impressifrons but larger and with much stronger bristles. Two basal segments of all tarsi yellow.

FEMALE. AS in male, but with wider frons, deeper, more conspicuous, frontal depression and broader antennae. Ovipositor similar to that of viriosa, but with less evident thickenings on sides at apical third, and apical segment longer and narrower.
