Diagnosis: the only known dark-headed (Palaearctic) Zimmermannia without hair-pencil in male. Male genitalia
characterised by pointed pseuduncus, narrow valvae and three pairs of almost similar carinae. Female characterised
by very dense bundle of extremely long setae on tergite 7.
Description. Male holotype. Forewing length 2.84 mm, wingspan 6.4 mm. Head: frontal tuft and collar dark brown.
Antennae broken. Thorax and forewings brown irrorate with white, with an mconspicuous white dorsal spot.
Hindwmg without hair-pencil, costal bristles or specialised scales; humeral lobe more or less distinct. Female paratype.
Forewing length 3.08 mm, wingspan 7 mm. Antennae long, with 41 segments. Male genitalia. Capsule length 403
µm, width 261 µm. Tegumen produced into cuspidate pseuduncus. Gnathos with long, slender central element
(in figure not in proper ventral view). Valva length 266 µm, narrow triangular, with indistinct inner lobe (mesal),
distally suddenly narrowed into fingerlike tip. Aedeagus 351 µm, hardly constricted; ventral carinae short, widely
separate, bifurcate; lateral and dorsal carinae similar in size and shape, horn-shaped, closely placed. Vesica difficult
to study in holotype, no special cornuti visible. Female genitalia. T7 with horseshoe-shaped dense bundle of extremely
long setae, reaching beyond abdominal tip. T8 with a row of about 20 long setae along anterior margin and with
many shorter setae on disc. Anal papillae with 30 — 32 setae. Posterior apophyses hardly reaching beyond
anterior apophyses. Vestibulum with indistinct sclerotisation. Corpus bursae 935 μm long, covered with
pectinations, partly in concentric bands around signa; signa similar, 399 and 424 µm long, 4.5 — 4.65 X
as long as wide. Ductus spermathecae with 4 1/2 convolutions. Larva unknown.
Hostplant: unknown. The specimens were taken at light in mountains with extensive woods of Quercus
baloot Griff., a relative of Q. ilex L. (Kasy, 1965), it is therefore possible that nuristanica is a barkminer of Q. baloot.
Only known from East Afghanistan: Nuristan.
