Zimmermannia monemvasiae

Diagnostic description: 

Diagnosis: male distinguished from the other Zimmermannia species treated here, by long brownish hair-pencil, surrounded by dark brown lamellar scales. Female by very dense bunch of long setae on abdominal tip dorsally. Male genitalia diagnosed by shape of vinculum, slender valvae with inner lobe, configuration of carinae and triangular cornutus and female genitalia by number of convolutions in ductus spermathecae and hairy T8 and T9.


Male. Forewing length 2.8 -3.36 mm (3.05 ± 0.19, 5), wingspan 6.5-7.5 mm. Head: frontal tuft and collar fuscous. Antennae very long, with 49-58 segments (53.2 ± 3.7, 5). Thorax and forewings brown, irrorate with white, sometimes an inconspicuous tornal spot white; cilia white beyond ill-defined cilia-line. Hindwing (fig. 13) with long brown hair-pencil, almost half as long as hindwing, surrounded by field of dark brown lamellar scales; humeral lobe prominent, costal margin with distinct emargination beyond hair-pencil.
Female (fig. 40). Forewing length 2.6-3.0 mm (2.83 ± 0.15, 5), wingspan 6.5-7 mm. Antennal segments 42-44 (43.3 ± 1.0, 4).
Male genitalia (figs. 93, 333). Capsule length 386-429 µm (3). Vinculum with ventral plate short, slightly excavate. Tegumen produced into blunt pseuduncus. Gnathos (fig. 285) with central element long and narrow, tapering towards sharp point. Valva (fig. 235) length 303-343 µm (3), narrow triangular, with prominent inner lobe in middle of valva; transtilla with very long ventral arm. Aedeagus (figs. 349, 351, 352) 437-467 µm (3), slightly constricted near opening of ductus ejaculatorius: ventral carinae long and parallel, fused near tip; lateral carinae small, almost triangular; dorsal carinae palmate, comprising each 4-5 teeth. Vesica with stout pointed triangular cornutus in addition to numerous small cornuti.
Female genitalia (figs. 31, 149, 150, 424). Along anterior margin of T8 (? partly on T7) crescent shaped bundle of more than 50 very long setae, easily visible in undissected material, setae pectinate (fig. 32), on rest of T8 many short setae, scales absent. Anal papillae with more than 30 setae. Posterior apohyses reaching beyond anterior apophyses. Vestibulum wide, without distinct sclerotisations. Corpus bursae 1040-1080 µm, covered with pectinations, partly in concentric bands around signa; signa elongate, slightly dissimilar, shortest 484-506 µm, largest 583-616 µm. Ductus spermathecae with 4½-5 convolutions.
Larva unknown.
