Wells, Alice & Contents, Arturs Neboiss Table Of, 2018, Australian Diplectroninae reviewed (Insecta: Trichoptera), with description of 21 new species, most referred to a new genus, Zootaxa 4415 (1), pp. 1-44 : 37-38

Arcyphysa flinti sp. nov.

( Figs 138–140 )

Material examined. Holotype ♂ (dry mounted), North-east Queensland, Palmerston National Park, Tchooratippa Creek , 5.ix.1972, O.S. & C.M. Flint ( NMV [PT-2007]).

Paratype 1♂, data as for holotype.

Diagnosis. In general body features this species groups with other species of Arcyphysa , and in lateral view of male genitalia resembles Arc. sybillae . However, unlike Arc. sybillae , it shares with Arc. acmea, Arc. anaplasis , and Arc. tortula phallic appatatus without parameres and harpagones bifid, and it differs from Arc. acmea, Arc. anaplasis and Arc. tortula in having the apicolateral processes on segment IX about as long as the gonopods, and not twisted and densely setose. In having the coxopodites of the gonopods, in ventral view, elongate triangular, Arc. flinti resembles Arc. tortula . Arcyphysa flinti is distinguished from that species by having the lateral extensions of segment IX in length not exceeding tergite X and only gently curved, not twisted.

Description. Male. Length of each forewing: 7.6 mm (n = 1).

Genitalia ( Figs 138–140 ): Abdominal segment IX in lateral view with elongate slightly curved process medially, arising apicolaterally, of equal width throughout length, extended to slightly less than apex of tergite X; tergite X ( Fig. 140 ) cleft apically in dorsal view; gonopods each with coxopodite stout, triangular, harpago divided, apices of lobes acute in lateral view; phallic apparatus without parameres, slender.

Female. Unknown.

Distribution. Known only from the type locality in north-eastern Queensland.
