Lonchaea hirticeps
L. hirticeps Zetterstedt is a rather small, dullish black species similar to L.
deutschi Zetterstedt. The tarsi, calyptrae, including margins and fringes, and
wings are brown, the eyes are pubescent, the oral setulae are arranged in a single
row; there are several hairs above the orbital bristle, there is a cluster of stigmatal
hairs, there are several hairs caudad of the sternopleural bristle, the disc of the
scutellum bears fine hairs; and the distance between the apices of Sc and ^
greatly exceeds the maximum width of the costal cell
Holotype, $, Redescribed.—ii^A about times as wide as high (9.66:8.0).
Frons (Fig. 4) somewhat wedge-shaped, but with narrowest part located at
about two thirds of distance between anterior ocellus and lunule; proportions,
slightly less than twice as long as wide (3.25 1.75); with dense, long hair i.e.,
the hairs distinctly longer than the oral setulae. Orbital plate with two or
three setulae arising dorsad of orbital bristle. Orbital bristle arising further
ventrad than anterior ocellus. Lunule (Fig. 4) with six, possibly eight setulae.
Parafacial narrow, about as wide as combined diameters of two average-sized
ommatidia; densely silvery polhnose. Cheek narrow (Fig. 7); with dense
short hair. Oral setulae arising anterior to lowermost extremities of compound
eye; rather weak; five or six in a single row (Fig. 7). Occipital setulae short;
mostly slightly projecting beyond the compound eye, but dorsal three or four
stronger. Compound eye with short pubescence, each hair nearly as long as
the combined diameters of two ommatidia.
Mesonotum dark brown, with uniformly dull brown pollen; with thick,
fine, moderately long hairs, bristles easily distinguished; several fine hairs caudad
of posterior dorsocentral bristles and between postalar and postintra-alar bristles.
Scutellum with four or five lateral setulae and five apical ones, disc with sixhairs, the anterior ones arising slightly cephalad of a line joining lateral scutellar
bristles. Epimeron with four or five stigmatal hairs. Mesopleuron hairy but
without anterodorsal bristles, with five posterior mesopleural bristles. Notopleuron
bare, except for two notopleural bristles. Sternopleuron with numerous
long hairs on dorsal half, sternopleural bristle scarcely longer than adjacent
hairs; four hairs arising caudad of sternopleural bristle. Pteropleuron bare.
Tarsi dark brown, but the two basal segments of all tarsi paler brown when
viewed from below. Anteroventral series of hairs of hind femur without out¬
standing bristles. Wings distinctly brownish fumose as in L. deutschi; distance
between apices of Sc and ^ nearly twice as great as maximum width of costal
cell (3.0:1.66). Calyptrae sandy-white, with dark brown margins and fringes.
Abdomen uniformly dusted with brown pollen, rather similar to L. deutschi.
Genitalia as shown in Figs. 19-21
