Jaschhof, Mathias & Jaschhof, Catrin, 2018, A needle in a haystack: the new genus Bernadottea (Diptera: Cecidomyiidae, Winnertziinae) with four new species in the Old World, Zootaxa 4379 (4), pp. 529-538 : 533

Bernadottea natalensis sp. nov.

Figs 1 , 2A–E

Diagnosis. The gonostylus, which is strongly bent and evenly broadened from the base to the middle, has a bipartite pectinate claw apically ( Fig. 2A ). Of the gonocoxites, the ventral emargination is shallow, broadly Vshaped and strongly sclerotized at the base ( Fig. 2C , ↓2), and the medial bridges are provided with long, curved, glabrous processes (↓3). The tegmen, whose apex is a rounded cap of complicated structure ( Fig. 2D , ↓4), is provided with a pair of strongly sclerotized, ventrally directed processes mediolaterally (↓5). The aedeagal bulge is conspicuous by the presence of numerous, small spikes covering its ventral surface ( Fig. 2C , ↓6).

Other characters. Body size 1.4 mm. Head. Eye bridge 2–3 ommatidia long dorsally. Flagellomeres 11; apical flagellomere simple; neck of fourth flagellomere 0.9 times as long as node ( Fig. 2E ). Wing ( Fig. 1 ). R1 = 3.5 times Rs. Abdomen. First tergite asetose; second to eighth tergites with a few lateral and no dorsal setae; pleural membrane asetose. Genitalia. Lateral lobes of ninth tergite small, rounded, microtrichose, space between lobes larger than their width ( Fig. 2B ). Gonocoxites: ventral portions extensively, darkly pigmented around emargination and along longitudinal axis, pointed posteriorly; dorsal portions with subrectangular lobes posteriorly ( Fig. 2C ). Gonostylar apex subrectangular, compressed laterally resulting in wedge-shape; outer claw twice the size of inner claw ( Fig. 2A ). Hypoproct broadly rounded posteriorly.

Etymology. The species epithet is derived from Natal, a now historical name of South Africa’s eastern province KwaZulu-Natal, where the holotype of this species was collected.

Holotype. Male, South Africa, KwaZulu-Natal, Pietermaritzburg, Karkloof Nature Reserve , alt. 1,325 m, mistbelt forest, 28.ix.–24.xi.2005, Malaise trap, M. Mostovski (in NMSA).
