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 : 534-536

Bernadottea pahangensis sp. nov.

Fig. 4A–E

Diagnosis. The gonostylus, which is broader than long, has an unusually large pectinate claw ( Fig. 4A , ↓1), but whether the claw is interrupted in the middle, or continuous and just depressed, is not clear. The gonocoxal emargination, whose outline is almost circular, is occupied by the aedeagal bulge, which has numerous, sclerotized hooks of various sizes ventrally and a pair of larger, pointed teeth laterally ( Fig. 4C , ↓2). The medial gonocoxal bridges are provided with glabrous, slender processes that protrude beyond the posterior gonocoxal edge ( Fig. 4C , ↓3). The tegmen of B. paHangensis , whose basic structure resembles that of B. natalensis , is unique in having an angular-shaped cap at the apex and a pair of finger-shaped processes dorsosubapically ( Fig. 4D , ↓4).

Other characters. Body size 1.1 mm. Head. Eye bridge 2–3 ommatidia long dorsally. Flagellomeres 10; apical flagellomere long, composed of two bodies; neck of fourth flagellomere 0.7 times as long as node ( Fig. 4E ). Wing. R1 = 4 times Rs. Abdomen. Tergal setae situated laterally; pleural membrane of anterior segments asetose, of posterior segments with single setae. Genitalia. Ninth tergite with wide, shallow emargination posteriorly ( Fig. 4B ). Gonocoxites: ventral portions extensively, darkly pigmented around emargination and along longitudinal axis, broadly rounded posteriorly; dorsal apodemes long, protruding beyond ventroanterior gonocoxal edge ( Fig. 4C ). Hypoproct broadly rounded.

Etymology. The specific epithet refers to Pahang, the federal state of Malaysia in which the holotype specimen was collected.

Holotype. Male, Malaysia, Malay Peninsula, Pahang, Genting Highlands , Awana , alt. 1,100 m, evergreen tropical broadleaf forest, 11.iii.1997, sweepnet, M. Jaschhof (in NHRS).
