Cabralis gloriosus Navás, 1912a:110 (547)

Type depository: BMNH. Holotype: male.

Type locality: Beira , Mozambique (19°49’S 34°52’E).

Etymology. Not originally stated, however, probably from Latin gloriosus , - a, - um, adjective (glorious, full of glory; famous, renowned). Probably referring to both Pedro Álvares Cabral and the striking beauty of the species (Pantaleoni, pers. comm.).

Material examined: 29 specimens from Zimbabwe, Mozambique ( BMNH, NMBZ, SANC, TMSA). See table 1.

Type material examined. Holotype: Database no.: BMNH00231; ♂ (BMNH). Label data: ‘Port. E. Afr. / Beira. / G.A.K. Marshall. / 1907-52.’ (White rectangle). ‘Cabralis / gloriosus / Nav.’ (White rectangle). ‘Type’ (Red bordered label). ‘BMNH(E) / 1239051’ (White rectangle). Abdomen cleared by Bakkes in 2014, placed in a glycerine-filled microvial pinned below specimen.

Diagnosis. Adults of species may be distinguished by (1) pronotal pattern of anteriorly-directed white trident shape with minor thickening on middle stripe ( Fig. 6 ), (2) male mediuncus thin curved in lateral view (Fig. 8).

Redescription. ♂ Length body 10–13mm, forewing 17–20mm, hind wing 15–18mm.

♀ Length body 12–14mm, forewing 19–21.5mm, hind wing 17–19.5mm.

Head with dark yellow hue. Thorax with pronotum dark brownish with anteriorly-directed white trident-like pattern comprising middle stripe and two shorter lateral stripes, middle stripe with minor thickening ( Fig. 6 ). Wings. Forewing marked with varying number of spots, large and strong, dark brownish and pale yellowish brown ( Fig. 5 ).

Abdomen dark brown, blackish. Male terminalia. Mediuncus strongly decurved, very long, narrow hook shape in lateral view (Fig. 8), apex flattened, bearing setae, dorsal face also bearing setae. Female terminalia. Sternite VII posterior margin deeply depressed, emarginate medially, forming narrow, slender, oblique copulatory fovea in ventral view (Fig. 13); invagination internal, posteriorly-directed, hook shape in lateral view (visible after maceration).

Egg. Length ± 1.5mm by width ± 0.7mm

Eggs laid singly in low numbers (observed specimen laid only one egg); not stalked (Fig. 15), oval in shape, reduced anterior micropylar projection (Fig. 15); gelatinous secretion for granular adhesion as noted by Tillyard (1919a) in Psychopsis elegans ( Guérin-Méneville, [1844]); coated in green, brown, whitish material seemingly derived from leaf or bark detritus (Fig. 15); bearing small, singly placed hairs protruding past outer margins (Fig. 15); egg laid in late January from wild-caught individual; egg was not reared.

Distribution. South-east Africa: eastern Zimbabwe, Mozambique ( Fig. 4 ). Moist and dense forest habitats, often associated with afromontane forests.
