Females clearly distinguished by white face spots and striking white fringes of T 1. Distal depression of T 2 laterally with ciliar bands. Maxillary palps shorter or as long as flagellomeres 1–5. Males are characterized by the white mask and white fringes on T 1. Tibiae 1 with white stripe, tibiae 2 sometimes with white stripe. Omaulus rounded in males and females. Boundary between vertex and occiput. Median furrow of propodeum shiny.</p><p><b>Distribution.</b></p><p>Canary Islands: La Palma.</p><p><b>Description.</b></p><p><b>Male</b>. N = 92, TL 4.8–5.8 mm. Head. HL: HW 0.84–0.91 (0.88), UFW: LFW 1.79–1.99 (1.89). Colouration: Antennae except the ventral part of flagellum black; pedicellus and apical flagellomere rarely completely black. Hairs white to brownish; dense dorsal pilosity of scapes as long as width of scape, pilosity below antennal sockets half the length of pilosity above antennal sockets, single hairs on vertex as long as spur of tibiae 2. Mask (Fig. 38 A): White colouration of clypeus and paraocular areae quite uniform, flecks of paraocular areae mostly starting distinctly higher than the lower edge of clypeus, terminating at lower level of antennal sockets, often with middle tip reaching upper level of antennal socket or beyond it [71 / 92], paraocular patches rarely start first at anterior tentorial pit. Pale colouration of supraclypeal area strongly reduced, consisting sometimes only of two little white spots [15 / 92], or totally black [6 / 92]. Anterior tentorial and epistomal pits not conspicuous. Supraclypeal area distally flattened and tapering, with shiny groove reaching the central ocellus. Paraocular areae distally moderately and densely punctate; frons above paraocular areae with fine to moderate and dense punctation, interspaces shiny; vertex not distinctly punctate, boundary to occiput rounded. Genae next to orbits with fine and dense punctation, changing to fine striation towards hypostoma. Malae narrow. Labrum with semicircular thickening and brownish hairs. Mandibles totally black or apically brownish. Maxillary palps shorter than flagellomeres 1–5: MP: FS (1–5) 0.80–0.95 (0.90).</p><p>Mesosoma (Fig. 38 B). Colouration black, calli occasionally with white dot or spot [9 / 92], or calli occasionally brownish [4 / 92]. Pilosity: mesonotum with long white upper pilosity, lower pilosity especially dense, not as short as that of females. Pronotum laterally broadening and rounded. Mesonotum with moderate, dense to close punctation, weakly shagreen, shiny. Scutellum with moderate close punctation, shiny. Sculpture of metanotum wrinkled with single moderate punctures, dull.

Legs black, tibiae 1 always white-striped, tibiae 2 frequently white-striped [62 / 92], tibiae 3 seldom white striped [16 / 92], partly only a brownish white dot. Alae hyaline, venation black. Propodeum: Inferior half of terminal area margined laterally by carina, lateral areae towards terminal area rounded, medial area separated by carinae, joining behind the horizontal area of medial area with a more or less broad, shiny groove, ending at base of terminal area. Medial area reticulately striped, towards terminal area with distinct shagreen.</p><p>Metasoma (Fig. 38 C). Colouration black. T 1 with white lateral fringes, each depression on T 2 and 3 laterally brightened and with a row of hairs; all terga shagreen, T 1 less shagreen at the base. Punctation of T 1 fine and dense, laterally and distally less dense and shiny, distal area of T 1 depression between fringes impunctate, sparsely shagreen. Following terga with minute, dense punctation. Sterna distally brownish, depressions shiny, punctation on the middle part of sterna moderate and dense, shagreen transverse, distal pilosity clear.
