Lonchaea mbeya
Description. Male: Head: Eyes sparsely covered in pale hairs, these slightly shorter than width of an ocellus. Frons
matt black, covered with light grey pollinosity. Frontal and interfrontal setulae numerous but relatively short,
approximately 0.2x length of orbital seta. Orbital plate sub-shining black, dulled by microsculpture, bare apart
from orbital seta. Lunule setulose, ground colour dull brown. Face and parafacials covered by light grey
pollinosity. Antennae black; postpedicel with a hint of orange-brown at extreme medial base, length to depth ratio
1.9:1. 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 3 anterior setae, 1 or
2 strong setulae in line 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 each with 1 seta. Prosternum bare. Scutellum heavily
grey pollinose, on margin with 3 setulae between apical and lateral setae, 0 between apical setae. Calypteres light
golden with a dense fringe of a similar colour. Wings light fumose, especially anteriorly. Wing length 4.1mm. Legs
all black, a brush of golden setulae on ventral surface of fore and hind metatarsi, this extending ventrally along
apical third of anterior tibiae. Hind femora apically with a single long antero-ventral seta, longer than femur is
wide.
Male terminalia: (Figs. 5–8): In lateral view epandrium with portion anterior to suture visible as a large
rounded lobe. Cerci membranous, relatively long and narrow with a fringe of short setulae on posterior and ventral
surfaces. Surstyli visible as a three pointed process extending postero-ventrally from shell of epandrium. In ventral
view a pair of long, tooth-like, ventrally projecting processes present at base of cerci, these bearing a single medial
setula. Posterior apodeme of hypandrium well developed, reaching to processes at base of cerci. In posterior view
posterior process of surstylus with three pointed, medially directed teeth arising from a single basal plate. Ventral
tooth the longest, curving dorsally, central and medial teeth similar in size, medial bearing a single pre-apical seta.
Parameres long and slender, curving gently to apex. Ventral surface, slightly apical of mid-point, with one medium
sized tooth, anterior to this a very small tooth. Anterior surface with a scattering of spinules on apical half, basal
ventral process small. Phallus, small, a simple tube arising from a basal plate
