Etymology

The specific epithet jordanicus refers to the provenance of the material.

Material examined

Holotype

BODY ( Fig. 2A ). 3.15 mm long. LFW 1.84 mm.

COLOURS. Head dark and mesosoma dark castaneous, nearly black, except pronotum dark castaneous; antenna, mandible and palpi light castaneous; tegula and legs dark castaneous, except tarsi light castaneous; wings sub-hyaline with wing venation dark castaneous; metasoma dark castaneous.

HEAD ( Fig. 2B ). Head longer than wide, narrow in lateral profile. Malar space shorter than vertex-ocular line, one parallel to the other in dorsal profile. Mandible wide apically, lower margin curved, with four sharpened apical teeth, lower tooth longer than immediately upper teeth, and wider than others. Palpi caliciform, and cylindrical in cross section. Clypeus with median lobe delimitated, quadrate, lateral lobe absent; median clypeal carina inclined in lateral profile, complete, line-shaped in dorsal profile, and below torulus. Antennal foraminal distance less than antennal foramen diameter. Antenna with conspicuous pubescence, erect, sparse, and long; scape slightly curved, with same diameter across extension; pedicel longer than wide, caliciform; flagellomeres long; first flagellomere as long as pedicel, as long as others. Eye small, round, glabrous, with contour even. Frons not foveolate. Ocellar triangle not compact, placed on posterior half of head; frontal angle of ocellar triangle right; ocellar fovea present and narrow; ocelli very small. Vertex convex. Dorsal and ventral half of occipital carina high, with side striate.

MESOSOMA ( Fig. 2 C–D). Pronotum with anterior slope inclined in lateral profile; pronotal plate not foveolate, without plate sulcus; pronotal disc as long as wide, coriaceous, trapezoidal, with anterior margin convex, anterior corner rounded, side slightly concave, without longitudinal pronotal sulcus, and posterior margin straight. Mesoscutum coriaceous and shorter than mesoscutellum; longitudinal mesoscutal sulcus absent. Notaulus complete, shallow, narrow, and polished. Parapsidal signum incomplete, shallow, and parallel. Axilla polished and shallow. Mesoscutum-mesoscutellar sulcus inconspicuous. Mesoscutellar sulcus narrow, arched, not dilated at ends, and fused with axilla. Mesoscutellum longer than wide, coriaceous, and touching propodeal disc. Metanotum overlapping lateral region of mesoscutellum. Propodeal disc 1.5× as long as wide medially, with central fovea fused with propodeal triangle fovea, with three carinae, median carina complete, with longitudinal ridge between median and inner discal carinae, sublateral and inner discal carina not fused anteriorly, inner discal carina complete, with sublateral carina, with lateral carina, posterior carina complete; spiracle elliptical; posterior spine absent. Declivity of propodeum coriaceous, with median carina and without lateral carina. Lateral surface of propodeum coriaceous, without upper and posterior carina. Mesopleuron coriaceous; acropleural sulcus continuous with mesopleural suture; posterior oblique sulcus present, foveolate, and complete; mesopleural suture with inner margin striate. Propleuron with epicoxal sulcus shallow and polished. Pleurosternum with epicoxal sulcus polished.

WINGS. Forewing with C cell very narrow and longitudinally folded; R cell shorter than 1Cu cell; 1Rs+2M vein angulate; 2Cu+cu-a vein bi-angulate; nebulous 3Cu vein absent; nebulous 2A vein absent; stigma developed, with distal margin convex; Rs+r-rs vein slightly curved forward, rising at distal margin of stigma.

LEGS. Protibia short, 1.5× first tarsomere length, with protibial spur long, longer than half length of first tarsomere. Metacoxa with dorsal expansion, but without ventral one. Tarsomeres I–IV conical, progressively shorter distad, with short spines; claw simple and arched, base with only strong tooth; arolium simple, angulate, and slender.

METASOMA. Metasoma 1.6× longer than wide; tergites I–VI and sternite I coriaceous and without lateral pilosity; sternites III–VI polished; with sparse setae at posterior margin of tergites II–VI. Hypopygium wider than long, with anterior margin unilobate, anterior corner angulate, lateral margin convergent posterad, and its lateral margin straight.

GENITALIA ( Fig. 4 A–C). Dorsal arm of paramere longer than ventral arm, “S”-shaped, and with basal margin narrow; ventral arm slender, with apex densely hairy, and inner margin straight. Basivolsella with cuspis bi-ramous, arms slightly indistinct, ventral arm not reaching apex of dorsal arm, slender, with apex rounded, dorsal arm wide and with apex rounded. Aedeagus slender and not reaching paramere apex level, with pair of apical lobes touching each other; with apical margin rounded, lateral of margin of basal portion slightly convex; apodeme divergent, base curved laterad; genital ring ventrad.

Remarks

This species is similar to Bradepyris proximus (Kieffer, 1906) in having the malar space parallel, the antenna with pubescence medium, the ocelli very small and the mesoscutum with notauli narrow and deep. However, the head of B. jordanicus sp. nov. is longer than wide, the antennae have sparse pubescence, the eyes are small, the pronotal disc is as long as wide, the mesoscutum is shorter than the mesoscutellum, the propodeal disc lacks a longitudinal ridge between the median and inner discal carinae and a sublateral carina is present, whereas B. proximus has the head as long as wide, the antennae with have dense pubescence, the eyes are large, the pronotal disc is shorter than wide, the mesoscutum is as long as the mesoscutellum, the propodeal disc has a longitudinal ridge between the median and inner discal carinae and a sublateral carina is absent.

Distribution
