Type depository: BMNH. Holotype: male.
Type
locality:
Beira
,
Mozambique
(

Etymology.
Not originally stated, however, probably from Latin

um

from

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).

Psychopsis elegans
(
Guérin-Méneville, [1844]

Zimbabwe
,
Mozambique
