( Figs. 55–57 View FIGURES 55 – 57 )
Material examined. HOLOTYPE, 3 labelled: D.R. CONGO, Kona , 13 May 2010, primary swamp forest (reg. 30038, leg. P. Grootaert, MS reference EC13); Holotype / Elaphropeza juakalyi / Grootaert et Shamshev sp. nov. ( RBINS).
Diagnosis. Species of E. ephippiata -group; recognised by yellow thorax but metanotum and anepimeron brownish; hind tibia with 2 anterodorsal bristles.
Description. Male. Length: body 2.7 mm, wing 2.3 mm. Occiput entirely black, subshining; with brownish yellow setation; inner verticals long inclinate, outer verticals hardly prominent. Anterior ocellars long proclinate and cruciate, posterior ocellars minute. Frons subshining, narrow, above antennae nearly as broad as anterior ocellus. Antenna with yellow scape and pedicel and brownish postpedicel and stylus; pedicel with circlet of subequally short setulae; postpedicel subtriangular, short, 2.4 times longer than wide; stylus with short pubescence, long, 3.2 times longer than postpedicel, 1.9 times as long as scape, pedicel and postpedicel combined. Proboscis yellow. Palpus yellow, small, rounded, covered with numerous black setulae, subapical seta short, thin.
Thorax largely yellow, with brownish setation; metanotum and anepimeron brownish, katepisternum and meron with brownish tinge on lower part, spiracles brownish. Prothoracic episterna without long upturned seta just above fore coxa, with minute seta on upper part. Postpronotal seta not prominent. Mesonotum with 2 long notopleurals (posterior longer), 1 moderately long postsutural supra-alar, 1 similar postalar and 4 scutellars (apical pair long, cruciate; lateral pair minute); acrostichals short, arranged in 4 irregular rows on anterior part of mesonotum, becoming 2-serial posteriorly, lacking on notopleural depression, hardly separated from dorsocentrals; dorsocentrals short, multiserial almost throughout, ending in 1 pair of long prescutellars (nearly as long as apical scutellars).
Legs long, slender, all femora of subequal width, with black setation, largely yellow, tibiae and tarsi of fore and mid legs brownish yellow. Coxae and trochanters with unmodified setation. Fore femur with rows of short anteroventral and similar posteroventral setae, 1 long seta near base, and short subapical seta anteriorly. Fore tibia lacking prominent bristles (except subapicals). Mid femur covered with spinule-like setae ventrally, bearing 1 long seta near base and 1 long strong subapical seta anteriorly. Mid tibia with black ventral spinules, lacking prominent setae (except subapicals). Hind femur with subequally short anteroventrals and several short erect dorsal setae near base. Hind tibia with 2 long anterodorsals; apical projection small, rounded, brownish yellow. Hind basitarsus with several subbasal subequally short spine-like setae.
Wing normally developed, finely infuscate, covered with uniform microtrichia; veins mostly yellowish brown, basal section of M1+2 (including short area beyond crossvein bm-cu), crossveins r-m and bm-cu pale; basal section of vein CuA1 thicker than basal section of vein M1+2. Costal vein with moderately long setulae along anterior margin. Costal bristle long, black. Costal index: 55/24/41. Vein Rs nearly as long as crossvein bm-cu. R1 uniform throughout. Vein R2+3 evenly bowed, uniformly sclerotised. Veins R4+5 and M1+2 somewhat divergent near wing apex, almost straight. Vein CuA1 reaching wing margin. Vein A1 lacking. Crossvein bm-cu somewhat oblique. Crossvein r-m before middle of cell bm. Calypter brown, with black setae. Halter darkened.
Abdomen. Tergite 1 pale yellow; tergites 2–3 represented only by small subtriangular lateral patches, with unmodified setae; tergite 4 broad, dark brown, with numerous squamiform setae laterally; tergite 5 narrow, brownish, with squamiform setae; tergites 6–7 broad, brownish, with unmodified setation; tergite 7 with long posteromarginal setae; tergite 8 unmodified. Sternites weakly sclerotised, undivided, with scattered, short, unmodified setae; sternites 5–7 broader, subrectangular; sternites 3–4 deeply concave posteriorly. Gland-like structure present between tergites 4–5, ampoule-like. Terminalia ( Figs. 55–57 View FIGURES 55 – 57 ) small, brownish yellow. Cerci separated; right cercus very narrow, digitiform, with several unmodified setae of different lengths basally; left cercus unbranched, digitiform, somewhat broader but nearly as long as right cercus, with 4 long subapical and some short unmodified setae; hypoproct not prominent. Epandrium completely divided. Right epandrial lamella ( Fig. 55 View FIGURES 55 – 57 ) rather subrectangular, rounded apically, covered with numerous unmodified setae of different lengths. Right surstylus not prominent. Left epandrial lamella fused to hypandrium, with 4 short setae apically. Left surstylus ( Fig. 57 View FIGURES 55 – 57 ) large, rather subglobular, with short unmodified setae. Phallus short. Two rod-shaped apodemes.
Female. Unknown.
Etymology. This species is dedicated to Dr. Jean-Louis Juakaly, the arachnologist on the Congo 2010 expedition.
Distribution. D.R. Congo.
Remarks. Among species described from D.R. Congo, E. juakalyi sp. nov. is most similar to E. monoseta sp. nov., E. incerta sp. nov., E. yaekela sp. nov. and E. congoensis sp. nov. The main differences between these species have been noted in the key. Also, the new species could be compared with E. pseudodispar Raffone, 1990 and E. angustifacies described from Sierra Leone. However, E. juakalyi sp. nov. primarily differs from E. angustifacies by having two anterodorsal bristles (vs. one) on the hind tibia; E. pseudodispar has yellow antennae and legs.
