Fig. 6 A–D

Diagnosis

The elongate gonostylus is markedly wedge-shaped all along the medial edge ( Fig. 6B ). The gonocoxites have conspicuously large membranous areas below the gonostyli (↓ 1, Fig. 6A ); the posteromedial protuberance is provided with a pointed, sclerotized process that projects ventrally (↓ 2, Fig. 6A ). The tegminal processes, with their multiple points, are reminiscent of deers’ antlers (↓ 3, Fig. 6C ).

Etymology

The specific epithet, cervus , is the Latin word for deer, an allusion to the antler-shaped tegminal processes found in this species. The name is a noun in apposition.

Material examined

Holotype

NEW ZEALAND: ♂, South Island, Tasman, Nelson Lakes National Park, Lake Rotoroa , 450 m a.s.l., 15 Jan. 2001, mixed podocarp / southern beech forest, Malaise trap, Department of Conservation St. Arnaud leg. ( NZAC, no. CEC1414).

Differential diagnosis

A remarkably similar species found co-occurring with G. cervus sp. nov. is G. tewaipounamu sp. nov. It differs in both the gonostylus, which has a pubescent bulge dorsobasally ( Fig. 16B ), and several details in the gonocoxites ( Fig. 16A ) and the tegmen ( Fig. 16C ). The posteromedial protuberance provided with

a sclerotized, pointed process is a character that G. cervus sp. nov. shares with G. orautahi sp. nov. (see below), but otherwise these two species are rather dissimilar.

Other characters

BODY SIZE. 1.7 mm.

HEAD. Eye bridge 2–3 ommatidia long dorsally. Nine flagellomeres retained; neck of fourth flagellomere 1.3 times the node. Palpus slightly shorter than head height, 4 setae-bearing segments, apical segment longest of all.

THORAX. Pronotal setae present.

WING. Length /width ratio 3.3. Rs short, one sixth of apicR 1.

LEGS. Basitarsal spines absent.

TERMINALIA. Posterior edge of ninth tergite slightly three-lobed, central lobe rounded, with about 12 megatrichia, flanked by angular-shaped, densely microtrichose side lobes ( Fig. 6C ). Gonocoxites ( Fig. 6A ): ventral emargination as broad as long, poorly delineated basally, flanked by rather large, subtriangular lobes; ventral setae sparse. Gonostylus parallel-sided, 3.0 times as long as broad ( Fig. 6B ). Apex of ejaculatory apodeme membranous, arrow-shaped ( Fig. 6A ). Tegmen with conspicuous pattern of sclerotization ( Fig. 6C ).

Distribution and phenology
