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
) large (long) with numerous long setae. Posteromedial desclerotized part of sternite 5 rather broad, microtrichia apparently born on small tubercles. Synsternite (
Fig. 51
) 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
) 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
). Subepandrial sclerite slightly higher than broad, with a more sclerotised narrow median part. Cercus desclerotised, with hairs but no bristles (
Fig. 54
). Anterior part of surstylus (
Figs 54–55
) 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
): the longer, ventral part with very short apical and a long subapical seta, the shorter dorsal part bare. Basiphallus (
Figs 52–53
) extended caudally. Distiphallus (
Fig. 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
) 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
) distinct but irregular in form.
Female postabdomen and genitalia. Tergite 8 (
Fig. 47
) rather large with numerous thick setae along entire caudal margin (easily seen in undissected specimens). Sternite 8 (
Fig. 48
) not divided into posterior lobes, sparsely microtrichose, medial part slightly darker. Tergite 10 (
Fig. 46
)
not
fused to cerci, with a pair of long setae. Cerci (
Fig. 46
) short with a pair of very long setae (easily seen under lower magnification). Spermathecae (
Fig. 45
) ovoid with somewhat narrowed base; apically curved spicules present on basal 2/5. Sclerotised part of duct about as long as spermathecae.
