( Figs 2–29 View FIGURES 2–18 View FIGURES19–29 )

Diagnosis. Elytron dark-brown, with outer margin pale yellow ( Figs. 2 View FIGURES 2–18 , 19 View FIGURES19–29 ). Male with eye big (slightly narrower than distance between eyes) ( Fig. 6 View FIGURES 2–18 ); 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 View FIGURES 2–18 ); sternum IX slightly longer than aedeagus, arms of similar length, bearing stout subapical setae, with internal margins divergent posteriad, apices rounded ( Figs. 13–15 View FIGURES 2–18 ). Female with antenna filiform ( Fig. 22 View FIGURES19–29 ); distance between antennal sockets slightly shorter than apical maxillary palpomere greatest width ( Fig. 23 View FIGURES19–29 ); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin almost straight ( Fig. 25 View FIGURES19–29 ); elytron subparallel-sided ( Fig. 19 View FIGURES19–29 ), sternum VI with posterior margin straight ( Fig. 26 View FIGURES19–29 ), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 28 View FIGURES19–29 ).

Description. Colour pattern ( Figs. 2–4 View FIGURES 2–18 , 19–21 View FIGURES19–29 ) 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 View FIGURES 2–18 , 25 View FIGURES19–29 ) widest at posterior angles, with lateral margins narrower than distance between elytral humeri, posterior angles acute. Hypomeron ventrally rounded ( Fig. 7 View FIGURES 2–18 , 24 View FIGURES19–29 ).

Male. Eye big (slightly narrower than distance between eyes) ( Fig. 6 View FIGURES 2–18 ), taller than head ( Fig. 7 View FIGURES 2–18 ); antennomere IV 3x longer than wide ( Fig. 5 View FIGURES 2–18 ); 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 View FIGURES 2–18 ); sternum VIII strongly emarginated ( Fig. 12 View FIGURES 2–18 ); 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 View FIGURES 2–18 ); syntergite lacking transversal and medial sutures ( Fig. 13 View FIGURES 2–18 ); aedeagus with phallus divergent basally, then subparallel, basal projections of parameres contiguous, paramere narrowing towards apex, apex internally sinuose ( Figs. 16, 18 View FIGURES 2–18 ).

Female. Antenna filiform, antennomere III 2x longer than pedicel ( Fig. 22 View FIGURES19–29 ); distance between antennal sockets slightly shorter than apical maxillary palpomere greatest width ( Fig. 23 View FIGURES19–29 ); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin almost straight ( Fig. 25 View FIGURES19–29 ); elytron subparallel-sided ( Fig. 19 View FIGURES19–29 ), sternum VI with posterior margin straight ( Fig. 26 View FIGURES19–29 ), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 28 View FIGURES19–29 ); ovipositor with proximal plates medially fused, longer than wide, weakly sclerotized ( Fig. 29 View FIGURES19–29 ).

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.
