(Figs 2–29)
Diagnosis. Elytron dark-brown, with outer margin pale yellow (Figs. 2, 19). Male with eye big (slightly narrower than distance between eyes) (Fig. 6); pygidium almost 2x longer than sternum VIII greatest length, with lateral margins subparallel, posterior margin with median third sinuose, lacking ventral keels (Figs. 10–12); sternum IX slightly longer than aedeagus, arms of similar length, bearing stout subapical setae, with internal margins divergent posteriad, apices rounded (Figs. 13–15). Female with antenna filiform (Fig. 22); distance between antennal sockets slightly shorter than apical maxillary palpomere greatest width (Fig. 23); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin almost straight (Fig. 25); elytron subparallel-sided (Fig. 19), sternum VI with posterior margin straight (Fig. 26), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight (Fig. 28).
Description. Colour pattern (Figs. 2–4, 19–21) overall dark brown, except by the translucent sternum VIII and outer margins of pygidium, and the yellow spots of rudimentary larval lanterns on sternum VIII. Pronotum (Figs. 8, 25) widest at posterior angles, with lateral margins narrower than distance between elytral humeri, posterior angles acute. Hypomeron ventrally rounded (Fig. 7, 24).
Male. Eye big (slightly narrower than distance between eyes) (Fig. 6), taller than head (Fig. 7); antennomere IV 3x longer than wide (Fig. 5); pygidium almost 2x longer than sternum VIII greatest length, with lateral margins subparallel, posterior margin with median third sinuose, ventral keels absent (Figs. 10–12); sternum VIII strongly emarginated (Fig. 12); sternum IX slightly longer than aedeagus, arms of sternum IX of similar length, bearing stout subapical setae, with internal margins divergent posteriad, apices rounded (Figs. 13–15); syntergite lacking transversal and medial sutures (Fig. 13); aedeagus with phallus divergent basally, then subparallel, basal projections of parameres contiguous, paramere narrowing towards apex, apex internally sinuose (Figs. 16, 18).
Female. Antenna filiform, antennomere III 2x longer than pedicel (Fig. 22); distance between antennal sockets slightly shorter than apical maxillary palpomere greatest width (Fig. 23); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin almost straight (Fig. 25); elytron subparallel-sided (Fig. 19), sternum VI with posterior margin straight (Fig. 26), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight (Fig. 28); ovipositor with proximal plates medially fused, longer than wide, weakly sclerotized (Fig. 29).
Etymology. The specific epithet magnoculus is a name in apposition, and comes from the Latin magnus, and oculus, which refers to the big eyes of this new species.
