Lonchaea patens
Species with practically bare eyes; hairs on jowls and mouthmargin conterminous, and tarsi yellow about base.
Species with practically bare eyes; hairs on jowls and mouthmargin conterminous, and tarsi yellow about base.
Male: . Head wide; frontal width opposite front ocellus compared with width of one eye about as 7 : 11, narrower in front; frons dull except on vertex
about base of all long bristles, and these bristles exceptionally long; some hairs on orbits above orbital bristle. Face very wide below, facialia (or facial
orbits) opposite front mouthmargin wider than usual, wider than third antennal joint, dusted rather brownish on middle part of lower half; face
black, the slight greyish dusting not sufficient to entirely hide the shining ground colour. Antennae practically as long as middle line of face, third
joint quite three times as long as broad. Hairs on front part of jowls below eyes almost as long as jowls are wide, but not continued upwards above
level of front margin of epistoma. Palpi narrower than usual, not wider than first antennal joint.
Thoracic disc obviously shining with microscopic brownish pile only present on side margins (where it is very inconspicuous), on a transverse
prescutellar band, and on scutellum; pleurae all similarly pilose though very inconspicuously so on some parts. The usual strong bristles present, but
general pubescence very long and dense, and some long hairs on disc of scutellum as well as between marginal bristles. Several stigmatical bristles
but only one propleural. No great difference in length and strength of front row of bristles on mesopleura from those behind them. Numerous long
bristly hairs on sternopleura including some above and behind the single strong bristle.Abdomen broadly ovate, fifth (last apparent) tergite not longer than fourth;
microscopic brownish pile rather obvious on first and second tergites, much less distinct on third (which is shining at sides), and on a narrow band at
base of fourth tergite. Hypopygium (fig. 7) of the vaginalis type but with exceptionally large anal lamellae.
Legs more hairy than usual, especially some hairs behind front tibiae much longer than tibia is wide. First and greater part of second joint of all
tarsi yellowish, obscurely so seen from above partly due to the numerous black hairs. Wings whitish with yellow veins, though those about base of wing and on
outer quarter of costa are darker; base of wing distinctly yellowish to slightly beyond humeral crossvein. The yellowish stigmal space rather long, about
three and a half times as long as middle crossvein, this latter about opposite and of mediastinal vein. Squamae with blackish marginal fringe.
Female: . Differing from male as follows: All pubescence everywhere shorter.eye about as 19 : 17, all shining, satin-like. Antennae rather longer than
middle line of face. Palpi broader. Thoracic pubescence much shorter, upper 2-3 bristles of front row on mesopleura rather stronger than others
behind them, the single strong sternopleural bristle much longer than the hairs. Abdomen more extensively shining, microscopic pile present only on
first tergite, on second except broadly at sides, and on extreme base about middle of third tergite. Pubescence shorter than in male but more
conspicuous than in most females. Ovipositor of the narrow vaginalis type and with similar hairs, i.e. close to base of apical section on upper side a pair
Frons much wider and more equal in width, compared with width of one
