Mesosoma coriaceous, with pronotum with anterior corner angled, and posterior margin sinuous; mesoscutum longer than mesoscutellum. Propodeal disc with longitudinal ridge between median and inner discal carinae. Mesopleuron coriaceous; posterior oblique sulcus present, foveolate, and complete. Forewing with nebulous 2Cu vein present; hind wing with six distal hamuli. Mesotibia with distal spine. Metasoma with hypopygium wider than long, with anterior corner angulate. Genitalia with dorsal arm of paramere longer than ventral arm and club-shaped; cuspis with arms hardly distinct; aedeagus slender, with apex not reaching paramere apex, and with apical margin rounded; apodema divergent, with base straight.

Etymology

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

Material examined

Holotype

SPAIN: ♂, Baleares, Marshall col. ( HNHM).

Description

BODY ( Fig. 3A ). 4.92 mm long, LFW 3.0 mm.

COLOURS. Head and mesosoma dark castaneous, nearly black; antenna and mandible dark castaneous, palpi castaneous; legs dark castaneous, except tarsi castaneous; tegula dark castaneous; wings doublebanded with venation dark castaneous; metasoma dark castaneous.

HEAD ( Fig. 3B ). Head as long as wide and narrow in lateral profile. Malar space shorter than vertexocular line, one parallel to the other in dorsal profile. Mandible wide apically, lower margin straight, 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 and rounded, without lateral lobe; median clypeal carina inclined, complete, line-shaped in dorsal profile, and below torulus. Antennal foraminal distance less than antennal foramen diameter. Antenna with pubescence, erect, sparse, and short; scape curved and with same diameter across extension; pedicel longer than wide and rectangular; flagellomeres long, first flagellomere longer than pedicel and as long as others. Eye small, elliptical, and glabrous. Frons not foveolate. Ocellar triangle not compact, placed on posterior half of head; ocellar fovea present and wide; frontal angle of ocellar triangle right; ocelli small. Vertex convex. Dorsal and ventral half of occipital carina high and with side striate.

MESOSOMA ( Fig. 3 C–D). Pronotum with anterior slope inclined in lateral profile; pronotal plate not foveolate, without plate sulcus; pronotal disc 0.83× as long as wide, coriaceous, trapezoidal, side straight, with anterior margin convex, anterior corner angled, and posterior margin sinuous; longitudinal pronotal

sulcus absent. Mesoscutum coriaceous and longer than mesoscutellum; longitudinal mesoscutal sulcus absent. Notaulus complete, deep, narrow, and polished. Parapsidal signum incomplete, deep, and parallel. Axilla polished and shallow. Mesoscutum-mesoscutellar sulcus inconspicuous. Mesoscutellar sulcus narrow, arched, dilated at ends, and fused with axilla. Mesoscutellum shorter than wide and coriaceous. Metanotum overlapping lateral region of mesoscutellum. Propodeal disc 1.34× 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 weakly strigulate, with median carina and without lateral carina. Lateral surface of propodeum striate, without upper and posterior carinae. Mesopleuron coriaceous; with 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.

WINGS. Forewing with C cell very narrow and longitudinally folded; R cell as long as 1Cu cell; 1Rs+2M vein angulate; 2Cu+cu-a vein biangulate; nebulous 2Cu vein present; stigma developed and with distal margin convex; Rs+r-rs vein slightly curved forward and rising at distal margin of stigma. Hind wing with Sc+R vein long; with six distal hamuli evenly separated one from another.

LEGS. Protibia short, 1.5× first tarsomere length, and with protibial spur short, shorter than half length of first tarsomere. Metacoxa without dorsal and ventral expansion. Mesotibia with distal spine. Tarsomeres I–IV progressively shorter distad, with short spines, and cylindrical in cross section; claw simple, arched, and base with strong tooth only; arolium simple, slender, and with apex angulate.

METASOMA. Metasoma 1.7× 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, and lateral margin straight.

GENITALIA ( Fig. 4 D–E). Dorsal arm of paramere longer than ventral arm and club-shaped; ventral arm slender, with apex glabrous, and inner margin straight. Basivolsella with cuspis biramous, with arms hardly distinct; ventral arm not reaching apex of dorsal arm, slender, and with apex rounded; dorsal arm wide and with apex rounded. Aedeagus slender, with apex not reaching apex of paramere, with pair of apical lobes touching each other, and with apical margin rounded; lateral margin of basal portion convex; apodeme divergent, with base straight; genital ring ventrad.

Remarks

This species is similar to Bradepyris proximus (Kieffer, 1906) by having the head as long as wide, the malar space parallel, the antennae with pubescence medium, the ocelli very small, the mesoscutum longer than the mesoscutellum, with notauli narrow and deep, and the propodeal disc with a longitudinal ridge between the median and inner discal carinae. However, B. baleariensis sp. nov. has the antennae with spare pubescence, the eyes glabrous, the pronotal disc with the anterior corner angled and the posterior margin sinuous, the parapsidal signum conspicuous, the mesoscutellar sulcus with dilation at its ends, and the propodeal disc with a sublateral carina, whereas B. proximus has the antennae with dense pubescence, the eyes setose, the pronotal disc with the anterior corner rounded and the posterior margin straight, the mesoscutum as long as the mesoscutellum, the parapsidal signum inconspicuous, the mesoscutellar sulcus without dilation at its ends, and the propodeal disc without a sublateral carina.

Distribution

Spain (Baleares Islands).
