Diagnosis. Males of this species can be distinguished from other Euglyptus species by the following combination of characters: body 1.51–1.61 mm (forebody 1.13–1.18 mm) ( Fig. 2A View Fig ); antennomere IX slightly wider than long, subhexagonal, X wider than XI (8: 7), widening to apex ( Fig. 2C View Fig ); pronotum gradually widening from anterior margin to middle, widest in middle, gradually narrowing from middle to posterior 1/3, parallel from posterior 1/3 to posterior margin, with shallow median longitudinal sulcus and broad transverse antebasal sulcus ( Fig.2B View Fig ); both parameres much shorter than elongate median lobe, dissimilar but both short and slightly curved to apical point; median lobe curved dorsally to right, apex slightly lobed and less sclerotized, apex slightly angled anteriorly as distinct blunt point that is most distinct in dorsal view ( Figs 2E–J View Fig ).

Redescription. Body 1.51–1.61 mm (forebody 1.13–1.18 mm); head and thorax impunctate; head, thorax, abdomen, elytra, leg, and antenna reddish-brown; tarsus and maxillary palpus yellowish-brown ( Fig. 2A View Fig ).

Head slightly wider than long, with small dorsal tentorial pits, impression weakly defined around dorsal tentorial pits; temples gradually narrowing toward posterior margin of head capsule, with several setae; impression between antennal tubercles as wide as antennal tubercle width. Pedicel wider than antennomeres III–VIII, antennomeres III–V longer than wide, subrectangular, VI–VII as long as wide, subquadrate, VIII smallest, IX slightly wider than long, subhexagonal, X wider than XI (8: 7), widening to apex ( Figs 2A, C View Fig ).

Pronotum wider than head, as long as wide, narrowest at anterior margin, gradually widening from anterior margin to middle, widest in middle, slightly narrowing from middle to posterior 1/3, parallel from posterior 1/3 to posterior margin, with shallow median longitudinal sulcus and broad transverse antebasal sulcus ( Fig. 2B View Fig ).

Elytra and abdominal tergite s lacking any distinguishing characters ( Figs 2A, D View Fig ).

Male genitalia. Both parameres much shorter than elongate median lobe, dissimilar but both short and slightly curved to apical point; median lobe curved dorsally to right, apex slightly lobed and less sclerotized, apex slightly angled anteriorly as distinct blunt point that is most distinct in dorsal view ( Figs 2E–J View Fig ).

Distribution. New Zealand (South Island: BR, NN, OL, WD; Fig. 16A View Fig ).
