Euconnus (Napochus) feeneyi parallelilaminatus ssp. n.

( Figs. 33–34 , 51–54 , 64 )

Type material studied. Holotype: AUSTRALIA (Queensland): ♂, three labels: " 11.45S 142.35E QLD / Heathlands 26Jan. –/ 29Feb.1992 P.Feehney / MALAISE #2 dump / open forest" [white, printed], "Aust. Nat. / Ins. Coll." [green, printed], " Euconnus / ( Napochus ) / feeneyi parallelilaminatus m. / det. P. JAŁOSZYŃSKI, '15" [red, printed] ( ANIC). Paratypes (7 ♂♂): 3 ♂♂, "11.45 142.35E QLD / Heathlands 1–21Mar. / 1992 P.Feehney / MALAISE #2 dump / open forest" [white, printed]; 1 ♂, " 11.45S 142.35E QLD / Heathlands 22Mar. –/ 25Apr.1992 T.McLeod / MALAISE #1 barracks / closed shrub(=heath)"; 1 ♂, " 11.39S 142.27E QLD / Cockatoo Ck.

Khalu" [white, printed] (paratypes in ANIC and cPJ).

Diagnosis. BL 1.08–1.30 mm; aedeagus in ventral view with long, narrow and nearly parallel-sided ventral apical projection with rounded apex, external lateral projections distinctly narrowing distally and with subtriangular pointed apices.

Description. This subspecies differs from Euconnus feeneyi feeneyi only in genital characters; all other structures are indistinguishable. Due to a small sample, only two distinctly different body forms were found, "short" ( Fig. 33 ) and "long" ( Fig. 34 ); measurements are given separately for each of them. "Short" form (N = 3): BL 1.08–1.10 mm (mean 1.08 mm); HL 0.23 mm, HW 0.24–0.25 mm (mean 0.25 mm), AnL 0.43–0.45 mm (mean 0.44 mm); PL 0.25–0.28 mm (mean 0.27 mm), PW 0.30 mm; EL 0.58–0.60 mm (mean 0.59 mm), EI 1.15–1.33. "Long" form (N = 5): BL 1.20–1.30 mm (mean 1.25 mm); HL 0.25–0.28 mm (mean 0.27 mm), HW 0.25–0.26 mm (mean 0.26 mm), AnL 0.48–0.53 mm (mean 0.51 mm); PL 0.28–0.30 mm (mean 0.29 mm), PW 0.30–0.31 mm (mean 0.31 mm); EL 0.65–0.73 mm (mean 0.70 mm), EW 0.50–0.53 mm (mean 0.52 mm), EI 1.30–1.38.

Aedeagus ( Figs. 51–54 ) stout, AeL 0.20 mm, as in Euconnus feeneyi feeneyi , except ventral apical projection very narrow and with parallel sides and external lateral projections with narrow and pointed apices.

Female. Unknown or indistinguishable from similar species (see discussion).

Distribution. N Queensland ( Fig. 64 ).

Etymology. The name parallelilaminatus refers to the parallel lateral margins of the aedeagal ventral apical projection.

Remarks. Holotype is one of "short" specimens; "short" and "long" specimens were labeled with a small white printed label with "short" and "long", respectively, to facilitate further study of this variability. Although the external appearance of "short" and "long" specimens is strikingly different ( Fig. 33 vs. 34), the aedeagi of extremely small and extremely large specimens selected from the type series differ only in slightly more slender ventral apical projection in the former and slightly more slender dorsal apical projection in the latter ( Figs. 51–52 vs. 53–54). These differences require further study, when a larger number of specimens becomes available.
