Diagnosis

This new species of Neurepidosis is peculiar for the plain construction of male terminalia structures, such as the simply subtrapezoid ninth tergite and the unmodified subcylindrical gonostylus. The elongate tegmen, which is slightly constricted medially, has unusually robust lateral walls (↓ 1, Fig. 13B ) and the aedeagal apodeme is unusually short and poorly sclerotized (↓ 2). Larvae and females of N. simplex sp. nov. are unknown.

Etymology

The specific epithet, the Latin adjective for ‘simple’, refers to the uncomplicated terminalia structures.

Type material

Holotype

Other characters

Male

BODY LENGTH. 1.6 mm.

HEAD. Eye bridge devoid of ommatidia dorsally. Scape and pedicel concolorous with flagellum. 14 flagellomeres; circumfila with 2 long posterior extensions, present on flagellomeres 1‒11; neck of fourth flagellomere 1.2× as long as node ( Fig. 13C ). Palpus 4-segmented, shorter than head height.

WING. Longer than body. Length / width ratio 2.9.

LEGS. Acropods: claws with single large tooth basally, empodia vestigial.

TERMINALIA ( Fig. 13B ). Posterior margin of ninth tergite straight or slightly concave. Gonocoxal synsclerite broader than long; ventral setae large; ventral emargination deeply V-shaped, its base reinforced by sclerotized margin; dorsoposterior portions markedly protruding beyond ventroposterior portions. Gonostylus twice as long as high, slightly tapered apically. Tegmen strongly sclerotized, elongate, slightly constricted beyond midlength, apex broad, truncate. Aedeagal apodeme hardly discernible, about as long as gonocoxal dorsal apodemes.
