Arcyphysa flinti

sp. nov.

Arcyphysa flinti  sp. nov.

( Figs 138–140View FIGURES 132–145)

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 138–140View FIGURES 132–145): 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. 140View FIGURES 132–145) 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.
