Rougemontius nov.gen. ( Figs 24 and 117-119 )

D i a g n o s i s: On the basis of its tarsal formula 4-5-5, of the moderately long galea and lacinia and of the widely separate mesocoxae the new species is attributable to the tribe Termitopaedini Seevers, 1957 . In the form of the ligula and the labial and maxillary palpi, the new genus is placed next to the genus Neotermitotecna KISTNER 1990 from Sierra Leone, but the tarsal formula in this genus is 4-4-4. In the antennae and the sculpture of the pronotum it is clearly different from the remaining genera of the tribe.

D e s c r i p t i o n: Head transverse; temples divergent posteriorly. Eyes very developed. Gula broad and long; mentum free. Labial palpi 3-segmented, ligula entire, paraglossae not protruding in front ( Fig. 118 ). Second segment of maxillary palpi relatively slender ( Fig. 119 ), the third segment fusiform, two-thirds longer than second. Antennae geniculate; scape long, second antennomere shorter than the first, third longer than the second, fourth as long as wide, fifth and sixth transverse, antennomeres seven to ten much longer than wide. Pronotum with inflated anterior angles very salient anteriorly, with wide and deep median depression that divides it into two posterior sulci, lateral margins sinuate. Elytra inflated, with angles protruding posteriorly and with disc deeply depressed. Wings present. Abdomen moderately inflated, broadest at level of fourth segment, twice as broad as pronotum. Abdomen with membranous integument exposed; the sclerites of each segment contiguous, but the sclerites of segments 3, 4, 5, and 6 well separated from those of adjacent segments. Basal paratergites moderately broad, those of fifth segment one-seventh as broad as tergite; distal paratergites relatively broad, those of fifth segment one-third as broad as tergite ( Fig. 24 ).
