Diagnosis. Males of this species can be distinguished from other Euglyptus species by the following combination of characters: body 1.14–1.16 mm (forebody 0.84–0.86 mm) (Fig. 3A); antennomere X wider than long, widest at apex, as wide as XI (Figs 3A, C); pronotum gradually widening from anterior margin to middle, widest in middle, gradually narrowing from middle to posterior margin, with broad and shallow median longitudinal sulcus, with broad transverse antebasal sulcus (Fig. 3B); ventral view of left paramere thick, slightly curved to middle, apex bluntly rounded, with prominent preapical truncate apophysis directed to right, right paramere thin, sinuate, obscured by left paramere, broad basally, narrowing and curving ventrally to acute apex; median lobe deeply split apically, with small preapical apophysis best seen in lateral view (Figs 3E–J). Description. Body 1.14–1.16 mm (forebody 0.84–0.86 mm); head and thorax impunctate; head, thorax, and abdomen reddish-brown; elytra, leg, antennal scape, and pedicel lighter than reddish-brown; antennomeres III– VIII, tarsus, maxillary palpus, and antennomeres IX–XI yellowish-brown (Fig. 3A). Head as wide as 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 narrow, width of impression area approximately 0.8 times as wide as antennal tubercle diameter. Pedicel wider than antennomeres III–VIII, antennomeres III–V subrectangular, V longer than wide, VI as long as wide, VII slightly larger than VI, VIII smallest, IX as long as wide, subhexagonal, X wider than long, widest at apex, as wide as XI (Figs 3A, C). Pronotum as wide as head, as long as wide, narrowest at anterior margin, gradually widening from anterior margin to middle, widest in middle, gradually narrowing from middle to posterior margin, with broad, shallow median longitudinal sulcus and broad transverse antebasal sulcus (Fig. 3B). Elytra and abdominal tergites without any distinguishing characters (Figs 3A, D). Male genitalia. Ventral view of left paramere thick, slightly curved to middle, apex bluntly rounded, with prominent preapical truncate apophysis directed to right, right paramere thin, sinuate, obscured by left paramere, broad basally, narrowing and curving ventrally to acute apex; median lobe deeply split apically, with small preapical apophysis best seen in lateral view (Figs 3E–J). Etymology. The specific epithet is a Latin adjective referring to the bifurcate apex of the median lobe. Distribution. New Zealand (North Island: WN, South Island: BR, NN, SD; Fig. 16D).
