Diagnosis: Laccocoris spurcus congoensis can be distinguished from its two known congeners in Tanzania by the longer body length of> 10 mm and the labrum half as long as wide and not reaching the distal labial segment. This subspecies has sharp posterolateral corners of the pronotum ( Fig. 19 ) and all of our specimens have brachypterous hindwings. However, if a different wing morph is discovered as is known to occur in the Democratic Republic of the Congo , the posterolateral corners of the pronotum probably will be of a different shape. Material examined: TANZANIA : Mbeya Region : Maboo stream at Mbeya Peak village , 8°50.432'S 33°25.060'E , 2433 m , 4.viii.2010 , R.W. Sites & A. Mbogho , vegetated pool of small high elevation stream, L-1207 ( NMSA , UMC ; 12♂ , 10♀ , 19 nymphs) . Distribution: Laccocoris spurcus congoensis was known from the Democratic Republic of Congo (Poisson 1949, 1951 b ), whereas the nominate subspecies is known only from Cape Province in South Africa . In Tanzania , L. s. congoensis was found in only one locality at high elevation at Mbeya Peak in Mbeya Region . Discussion: Laccocoris spurcus is one of the largest species of Laccocoris in Africa. The nominotypical subspecies is known from South Africa (Stål 1865). Poisson (1949) described a subspecies from Democratic Republic of the Congo which is known to have wing polymorphism with which are associated differences in pronotum shape. Poisson (1949) reported that approximately 90 % of the individuals from Democratic Republic of the Congo were brachypterous and 10 % macropterous. We collected only hindwing brachypterous individuals of this species from a single location in Tanzania .
