Diagnosis
The structure of the embolus allows easy identification of this species and distinguishing it from its congeners. The embolus forms only a single loop at the base and has a very thin, thread-like tip. Epigyne is slightly similar to that in females of Massagris maculosa Wesołowska & Haddad, 2018, but copulatory ducts are thinner in the initial part and form fewer twists in the further part – compare Fig. 42F with Wesołowska & Haddad (2018: fig. 87).
Etymology
The specific name is derived from the type locality.
Material examined
Holotype
UGANDA • ♂; Masindi distr., Budongo Forest; 1°45′ N, 31°25′ E; dry season; 15–25 Jan. 1997; T. Wagner leg.; ZFMK 2873.
Paratypes
Uganda • 1 ♀; same collection data as for holotype; ZFMK 2873 • 1 ♂; same locality as for holotype, 21–31 May 1995; T. Wagner leg.; ZFMK 2938.
Description
Male
MEASUREMENTS. Cephalothorax length 1.9–2.1, width 1.4–1.6, height 0.9–1.0. Eye field length 1.1–1.2, anterior width 1.1–1.2, posterior width 0.9–1.0. Abdomen length 2.0–2.1, width 1.2–1.3.
CARAPACE. Pear-shaped, moderately high, gently sloping posteriorly; eye field large, eyes set on tubercles; fovea long, sulciform. Thoracic part of carapace brown, eye field lighter with two blackish longitudinal central marks, eyes surrounded by black area. Some faint hairs on carapace, longer bristles near first row of eyes. Sternum dark yellow, labium and endites brownish with light tips. Chelicerae with two teeth on promargin and five small teeth set together on retromargin (Fig. 42A). Long, dorsal bristles on outer surfaces of chelicerae, bent towards dorsum (Fig. 41A).
ABDOMEN. Ovoid, creamy white (silver guanine crystals translucent through integument), with grey marks on sides. Venter whitish, spinnerets light.
LEGS. Yellow to light brown. Leg hairs thin and short, brown.
PALPS. As in Figs 41B–D, 42B–D. Cymbium narrow (Fig. 42D), bulb short, embolus thin with single basal loop (Figs 41B, 42B).
Female
General appearance as in Fig. 40E. Similar to male, slightly lighter coloured.
MEASUREMENTS. Cephalothorax length 2.2, width 1.7, height 1.1. Eye field length 1.3, anterior width 1.2, posterior width 1.1. Abdomen length 2.9, width 2.0.
CARAPACE. Silver spots formed by translucent guanine crystals, covering eye field.
ABDOMEN. White with mosaic of grey spots on sides.
LEGS. Whitish. Palps also white.
EPIGYNE. Weakly sclerotized, with two widely separated shallow depressions (Figs 41F, 42E). Internal structure as in Fig. 42F, copulatory openings placed laterally, thin copulatory ducts initially straight, in further part forming several loops, spermathecae compact, multichambered.
