Diagnosis

Characters specific to G. didhami sp. nov. are the gonocoxites, whose posteromedial protuberance has a distinctive pattern of sclerotization (↓ 1, Fig. 7A View Fig ); the roundish lobes flanking the protuberance are inconspicuous (↓ 2, Fig. 7A View Fig ); the ventral emargination is sclerotized basally (↓ 3, Fig. 7A View Fig ); and ventral setae are reduced to the lateral portions. The tegminal processes have multiple small tubercles and points, which are harder to discern than Figure 7B View Fig (↓ 4) suggests. The ninth tergite has a broadly rounded posterior edge, whose vestiture is of ordinary microtrichia and setae of various sizes.

Etymology

This new species is named after Raphael K. Didham, ecologist at The University of Western Australia, Perth, who collected several of the specimens studied here, including the holotype of G. didhami sp. nov.

Other characters

BODY SIZE. 1.5 mm.

HEAD. Eye bridge 1–2 ommatidia long dorsally. Six flagellomeres retained; neck of fourth flagellomere 1.3 times the node. Palpus shorter than head height, 4 setae-bearing segments, apical segment longest of all.

THORAX. Pronotal setae present.

WING. Length /width ratio 3.1. Rs short, one sixth of apicR 1.

LEGS. Basitarsal spines absent.

TERMINALIA. Gonocoxites: membranous areas below gonostylus small ( Fig. 7A View Fig ). Gonostylus twice longer than broad, with slight depression above densely microtrichose apex ( Fig. 7A View Fig ). Sclerotized portion of ejaculatory apodeme slightly thickened apically, covered by membranous cap ( Fig. 7A View Fig ).

Distribution and phenology

The only specimen known of G. didhami sp. nov. was Malaise trapped at the height of summer in the native bush of Stewart Island, the smallest and southernmost of New Zealand’s main islands. The same Malaise trap collected simultaneously two other species of Glemparon : G. nativitas sp. nov. and G. rakiura sp. nov.
