Description. Male: Head: Eyes sparsely covered with pale hairs, these slightly shorter than width of an ocellus.
Frons matt black, covered with light grey pollinosity, frontal and interfrontal setulae numerous, relatively short, not
more than 0.2x length of orbital seta. Orbital plate sub-shining black, dulled by microsculpture, bare apart from
orbital seta. Lunule setulose, ground colour black. Face and parafacials light grey pollinose. Antennae black;
postpedicel obscurely orange-brown at extreme medial base, length to depth ratio 2.3:1. Arista with microscopic
pubescence. Anterior genal setae in a single, well-spaced row of 5 along mouth margin.
Thorax: Scutum sub-shining black, thoracic sclerites grey pollinose. Anepisternum with a row of 3 anterior
setae, 1 or 2 strong setulae lying ventral to these, 4 posterior setae, remainder of sclerite with a scattering of setulae
almost as long as the setae. Katepisternum with 2 strong setae, posterior slightly stronger than anterior, remainder
of sclerite with a few short setulae. Proepimeron and proepisternum with 1 seta. Prosternum bare. Scutellum
heavily grey pollinose, margin with 4 setulae between apical and lateral setae, 2 between apical setae. Calypteres
light golden with a rather dense fringe of a similar colour. Wings light fumose, especially anteriorly. Wing length
4.4mm. Legs entirely black, a ventral brush of golden setulae on fore and hind metatarsi, this extending ventrally
along apical third of anterior tibiae Male terminalia: (Figs. 2–4): In lateral view epandrium with portion anterior to suture visible as a small
rounded lobe. to suture with t10. Cerci membranous, upright and roughly rectangular with a fringe of short setulae
on ventral margin and apex. Surstyli visible as a large two pointed process extending postero-ventrally from shell
of epandrium, In ventral view a pair of flat, blade-like, pointed processes located at base of cerci, these extending
ventrally. Posterior process of hypandrium well developed, reaching to base of cerci. Posterior process of surstylus
with two pointed, medially directed teeth arising from a single basal plate. Ventral tooth the longest, curving
dorsally, dorsal tooth with a small rounded basal process and a more pointed sub-apical process. Parameres long
and broad, apical half with a group of long setulae and numerous denticles, ventral margin with large teeth and
numerous serrations. Ventral process large, reaching more than half way from base of cerci to apex of paramere,
bearing a row of short setulae. Phallus, a small simple structure similar to that of L. mbeya (Fig. 8).
