Mesandrothrips lamingtoni
sp.n.
(
Figs 14
, 22)
Male microptera.
Body and femora light brown, with head and tube darkest; antennal segments IV–VIII dark brown, III yellow in basal third and light brown distally, I and II slightly paler than head; tarsi, tibiae and apices of femora yellow; major setae pale. Antennal segment III slender in basal third (
Fig. 14
), apex angular, with slender sense cones; IV–VII each with distinct pedicel. Head scarcely longer than wide (
Fig. 22
), vertex with no sculpture; posterior ocelli faintly indicated; postocular setae weakly capitate, longer than dorsal eye length; maxillary stylets wide apart, V-shaped, retracted almost to postocular setae. Pronotum without sculpture lines, anteromarginal setae minute; four pairs of long, weakly capitate major setae. Mesonotum weakly sculptured, lateral setae softly pointed; metanotum without sculpture lines, median setae small and acute. Fore tarsal tooth pointed, longer than half tarsal width (
Fig. 22
). Fore wing lobe small, with two long setae at apex. Mesopresternum reduced to two small triangles. Pelta small and triangular; tergites II–VII each with 2 pairs of minute wingretaining setae, marginal setae S1 weakly capitate and longer than each of their tergites, setae S2 on VII long and finely acute; tergite IX setae S1 bluntly pointed, S2 shorter and stouter. Sternite VIII without a pore plate.

Comments
. All four of the available specimens are remarkable for the lack of sculpture on the head, pronotum and metanotum. Each of the three female specimens has the maxillary stylets dissociated.
