Milichia brevirostris
Content
Description
Female: Head black except for orange-yellow base of first flagellomere, arista and palpi. First flagellomere and palpi only at distal margin brown. Frons, lunule, pedicellus and face grey microtomentose. Colour of microtomentum on frons changing from grey to brown near vertex. First flagellomere and palpi with white pubescence, which is twice as long on palpi as on first flagellomere. Frons parallel sided, 1.2x as long as broad and 0.3x the width of head. Interfrontal hairs weak, in a row of about six hairs and some scattered hairs lateral of the rows. Foremost pair longest. Frontal triangle small, not extending further than ocelli. Two orbital setae, upper one reclinate, lower one proclinate and an additional small proclinate seta standing between these, but slightly closer to the eye. No frontal setae, but about four hairs. Pro- and lateroclinate ocellar and inner and outer vertical setae present. Postocellar setae parallel. Orbital and frontal plates only distinguished by thicker microtomentum. Lunule short, height about half the length of first flagellomere, with one pair of setae (fig. 6). Head in lateral view similar to M. argyratoides Collin, 1921 and M. cornesi Deeming, 1976 in respect to the slight angle in the posterior eye margin (fig. 1, pl. XVII in Collin 1921, and fig. 1 in Deeming 1976). Genae very narrow, vibrissa strong, followed by a row of setae, which get shorter at the back of the head. Face short (fig. 6), antennae small, pedicellus slightly shorter than first flagellomere. First flagellomere slightly broader than long. Palpi shaped like halfcircles with rounded edges and a few scattered short setulae (fig. 7). Length of palpi: 0.36 mm, breadth: 0.23 mm. Proboscis completely covered by palpi at rest. Shape of labella as in M. myrmecophila.
Thorax black. Mesonotum brown microtomentose except anteriorly, scutellum brown microtomentose. Anterior end of mesonotum and pleura grey microtomentose. Basisternum similar to shape "G" in Speight (1969). Chaetotaxy: 1 postpronotal, 2 notopleural, 1 presutural, 1+2 supraalar, 2 postalar, 1 long and 1 short dorsocentral, 1 long prescutellar, 1 cruciate apical and 1 subapical scutellar, 3 katepisternal and no anepimeral setae. Setae long and conspicuous.
Legs black except for yellow knees; grey microtomentose except for polished and glabrous posterior side of hind femur. Basal two tarsomeres of hind leg with anteroventral row of short setulae and ventral brush of yellow setulae.
Wings and squamae hyaline, veins yellow-brown. Distal end of subcosta and R1 and costa in front of subcostal break darkened. R4+5 and M1+2 parallel. Distal section of M1+2 slightly longer than penultimate section. Cell CuP closed. Halteres black. Length of wing: 2.6 mm.
Abdomen black, tergites brown microtomentose except for tergite one and basal half of tergite two, which get more greyish lateral, and except for hind margins of tergite two to five, which are grey microtomentose. Shoulders of tergite two with tuft of setae.
Body length: 2.0 mm.A
