Redescription of this species is given by RICHARDS (1973), so only postabdominal structures of both sexes are described here.

Male postabdomen and genitalia. Sternite 5 ( Figs 49–50 View Figs 49–53 ) large (long) with numerous long setae. Posteromedial desclerotized part of sternite 5 rather broad, microtrichia apparently born on small tubercles. Synsternite ( Fig. 51 View Figs 49–53 ) very characteristic: right half of sternite 6 greatly narrowed, sternite 7 extended towards the right side as a curved, heavily sclerotised dark sclerite. Medial and right portions of sternites 6 and 7 forming a distinct pocket. Sternite 8 part also larger than usual; male terminalia therefore larger than usual. Epandrium ( Fig. 54 View Figs 54–60 ) with a large transparent and less sclerotised posteroventral part bearing shorter setae, epandrium otherwise with numerous long setae. Hypandrium with apodeme shorter than phallapodeme ( Fig. 53 View Figs 49–53 ). Subepandrial sclerite slightly higher than broad, with a more sclerotised narrow median part. Cercus desclerotised, with hairs but no bristles ( Fig. 54 View Figs 54–60 ). Anterior part of surstylus ( Figs 54–55 View Figs 54–60 ) with large, ventrally directed anterior part and a relatively small posterior part, which bears a thin transparent lamella medially. Posterior part of surstylus deeply bifid ( Figs 54–56 View Figs 54–60 ): the longer, ventral part with very short apical and a long subapical seta, the shorter dorsal part bare. Basiphallus ( Figs 52–53 View Figs 49–53 ) extended caudally. Distiphallus ( Fig. 53 View Figs 49–53 ) with both dorsomedial and ventromedial rib, which are united basally into a strong wide sclerite. Distiphallus microtrichose between the sclerotised ribs. Postgonite ( Fig. 52 View Figs 49–53 ) robust, without basal caudal projection; basal part broader and rounded caudally. Apical part rather stout with a minute anteriorly curved apex. Ejaculatory apodeme ( Fig. 52 View Figs 49–53 ) distinct but irregular in form.

Female postabdomen and genitalia. Tergite 8 ( Fig. 47 View Figs 41–48 ) rather large with numerous thick setae along entire caudal margin (easily seen in undissected specimens). Sternite 8 ( Fig. 48 View Figs 41–48 ) not divided into posterior lobes, sparsely microtrichose, medial part slightly darker. Tergite 10 ( Fig. 46 View Figs 41–48 ) not fused to cerci, with a pair of long setae. Cerci ( Fig. 46 View Figs 41–48 ) short with a pair of very long setae (easily seen under lower magnification). Spermathecae ( Fig. 45 View Figs 41–48 ) ovoid with somewhat narrowed base; apically curved spicules present on basal 2/5. Sclerotised part of duct about as long as spermathecae.

Distribution – Rwanda and Zaire (occurrence data for L. decisetosa , see

ROHÁČEK et al. 2001, PAPP 2008 and MARSHALL et al. 2011); Ethiopia, South Af-
