Description. A typical representative of L. longicollis subgroup. Male body about 7 mm long, slender and leggy, resembles a racehorse. Body dark except for apices of femora and basal half of tibiae. Head with dark frons, yellowish and narrow frontal triangle. Fronto-orbital plates, parafacials, face, gena and occiput whitish-grey dusted. Antenna dark, long, postpedicel falling of mouth margin by 1/4 of its own length. Aristal hairs as long as antenna width. Palpi yellow. Thorax. Scutum black, with brownish dusting; pleura grey dusted; 2+4 dc (strong, strong, weak, weak, strong, strong); meron with 3–5 hairs above hind coxa, anepimeron with 10–12 setulae. Wing with vein M distinctly curved at apex ( Fig. 22). Legs. t1 with short p; t2 with 1 p and 1 av; t3 with median 1 av (weak), 1 ad and 1 pd; f3 dorsally curved, with 2(3) fine and long v setae at base and 1 short av at apex. Hind tarsus modified: tar3-1 strongly outward curved, with rows of av and pv hairs 3x as long as tarsus width. Abdomen whitish-grey dusted, with large trapezoid black spots on tergites 3 to 5 ( Fig. 22). Cercal plate as in Fig. 23.

Female differs as follows: body length about 7.5 mm; dusting of head yellowish, body dusting denser; f3 without fine v setae at base; hind tarsus unmodified.

Diagnosis. The previous misidentification of the species as L. paraneo is discussed below in Addendum. L. confusa is closely related to North African L. cilitarsis . As a lumper I did my best not to describe this species but Tanzanian specimens convinced me to do so. L. confusa and L. cilitarsis are sympatric in Tanzania with no intermediate specimens. Males differ as follows:

— Mid tarsus without a row of p setulae, only normal ground setulae hardly longer than tarsus width; cercal plate as in Fig. 23.

The southern part of Africa till Tanzania......................... confusa sp. nov.

— Mid tarsus with a row of curled setulae on p surface from apex of tar3-1 to tar2-5, these setulae at least 2x longer than tarsus width; cercal plate as in Fig. 24. The northern part of Africa till Tanzania.... cilitarsis Loew

Unfortunately, females of these species are indistinguishable.

Etymology. The name refers to my previous misidentification of this species.
