Redescription.
Female. Upper edges of eyes separated (
Fig. 70
), ocular bridge composed of four rows of facets (
Fig. 71
). Lower part of frontoclypeus with large, almost rectangular patch of inserted hairs, narrow medial stripe of pits ending between upper edges of eyes, and short stripe on both sides. Minimum distance between upper edges of eyes slightly larger than facet diameter. Ratios of distance of tangential points of ends of eyes to minimum width of frons 6.3: 1, to facet diameter 7.3: 1. Antennae with 16 segments (
Figs. 72
,
77
). Scape cylindrical, twice as long as pedicel, the latter is bowl-shaped. Flagellomeres 1-10 amphora-shaped, last four flagellomeres fused, almost globular and almost gradually reduced, last three flagellomeres minute (apical one smallest) and in comparison to preceding segments with long neck. Antennomeres 13 and 15 spined. Sensory filaments (
Fig. 77
) conspicuous and well visible, with three branches. Length ratio of maxillary palpomeres 1.1: 1: 1: 1.4 (
Fig. 73
). All palpomeres with transversal rows of small bristles. Terminal lobe of labium with four digitiform projections and three long setae (
Fig. 78
). Maximum length of cibarium equal to 1.2 times length of epipharynx. Thoracic sclerites as in
Fig. 79
. Wing (
Fig. 74
) widely lancet-shaped, 2.0-
2.4 mm
long, inconspicuously clouded, conspicuously and narrowly so only between costal margin and R
1
and in short line between R

apex of wing; veins r-r, r-m and m-m not visible; medial wing angle (BCD) 100°; wing indices: AB: AC: AD = 2.9: 3.4: 2.7; BC: CD: BD = 1: 1.6: 2; maximum length of wing equal to 2.4 times its maximum width. Maximum length of haltere equal to 3.5 times its maximum width. Ratios of lengths of femora, tibiae and first tarsomeres: P
1
= 2.7: 2.9: 1; P
2
= 3.3: 3.9: 1.2; P
3
= 3.5: 4.3: 1.2. Fore claws S-shaped (
Figs. 75
,
80
). Subgenital plate of characteristic shape (
Fig. 81
) with three lobes: middle lobe long, Y-shaped, external lobes shorter, pointed, with small inner lobuli, hairy; sensory digit of middle lobe developed, with two setae and characteristic three-armed sclerites below, connected with genital chamber (
Figs. 82, 83, 84
); plate with numerous long setae distally. Cercus long, slightly bent (
Fig. 76
).
Figs. 70-76.
Psychodula harrisi
(
Satchell, 1950
)
, ♀. 70 – head; 71 – facets; 72 – basal antennomeres; 73 – maxilla and maxillary palpus; 74 – wing; 75 – dorsal view of fore claw; 76 – lateral view of cercus. Scales = 0.1 mm (Figs. 70-73, 75-76); 1 mm (Fig. 74).
Male. Unknown to us; shortly described and figured (male genitalia) by
SATCHELL (1950)
.
Differential diagnosis.
The female of this species is similar to
Psychodula minuta
(Banks, 1894)
by its size and the fusion of the last flagellomeres; however, its subgenital plate (
Fig. 81
) uniquely shaped, composed of three characteristic lobes (
Figs. 82, 83, 84
), and bearing numerous long setae. In
P. minuta
, the subgenital plate is compact, shortly tongue-shaped and without deep clefts or long setae, but with two small, apical, horizontally oriented lobuli.
Figs. 77-84.
Psychodula harrisi
(
Satchell, 1950
)
, ♀. 77 – apical antennomeres; 78 – dorsal view of terminal lobe of labium; 79 – lateral view of thoracic sclerites; 80 – lateral view of fore claw; 81 – subgenital plate; 82 – dorsal view of genital chamber; 83 – same, anterior view; 84 – same, lateral view. Scales = 0.1 mm.
Bionomy.
DUCKHOUSE (1966)
stated that the species breeds in cow dung, chicken dung or wet garden rubbish.
