Tsacasiella instabilis (Tsacas, 1969) ( Figs 217–223 )

Neomochtherus instabilis Tsacas, 1969: 19–21 .

Tsacasiella instabilis ; Lehr, 1996: 73.

Type material: Holotype: DR CONGO: 1ơ [seen], ‘Holo- / type’, ‘Kambove, [10 ° 52'S: 26 ° 35'E] / Katanga. / 2.4.07 / 4,000 – 5,000 ft. ’, ‘Neave Coll / 1907-230’, ‘ Neomochtherus / instabilis n.sp. / Holotype M / L. Tsacas Det 1967’ ( BMNH).

Material examined: MALAWI: 2ơ 2^, 80 km S. of Mzimba, SE1233BC, 27.ii.1987, J. & A. Londt, Long grass & trees near Luwelezi river .

Type locality: Democratic Republic of Congo, Kambove .

Comments : Although the Malawi material bears a strong resemblance to the holotype, especially with respect to the male genitalia, minor differences, considered to represent individual variation, do exist. Far more new material is required before a good understanding of the species can be achieved .
