Lonchaea postica
Saproxylic
Peristomal bristles in single row in front. Legs
entirely black. Squamal fringes pale. Third antennal joint rather longer
than in contigua , and area around prescutellar thoracic bristles not micro¬
scopically pilose. (J. With the characters of contigua , except frons slightly wider; peristomal
bristles finer and those in front shorter and placed closer together. Antennae
longer, extending to lower margin of face, third joint obviously longer
and wider.Thorax with prescutellar area dulled by microscopic pile only in front of
basal angles of scutellum, central part shining. Bristles in front of usual two
pairs of long dorsocentrals and one pair of acrostichals only hair-like though
some of them are longer than pubescence on rest of thorax. Usually 1-2 hairs
behind the strong sternopleural bristle.
Abdomen not entirely dusted, the sides of third, nearly all fourth, and
fifth tergite (except perhaps on extreme basal margin) without dust or pile.
Hypopygium (fig. 14) very different,, inner laminate processes with a
projection at end, and penis jointed, the end portion apparently very short.
Wings with middle crossvein usually opposite end of mediastinal vein.
$. Frons at middle rather more than one-third width of head but slightly
narrower in front. Antennae longer and wider, extending below lower margin
of face. Thorax as in male but pubescence shorter. No hairs behind strong
sternopleural bristle. Abdomen dusted only on first, second and base of third
tergite. Hairs on last section of ovipositor much shorter, basal pair above
very minute.
Length 3.5-4.5 mm.
