(Figs 30–57)
Diagnosis. Elytron dark-brown (Figs. 30, 48). Male with eye small (half as wide as distance between eyes) (Fig. 34); pygidium almost 2x longer than sternum VIII greatest length, with lateral margins subparallel, posterior margin with median third rounded, lacking ventral keels (Figs. 38–40); sternum IX slightly longer than aedeagus, arms of similar length, bearing stout subapical setae, with internal margins subparallel, apices truncate (Figs. 41– 43). Female with antenna filiform (Fig. 51); distance between antennal sockets wider than apical maxillary palpomere greatest width (Fig. 52); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin rounded (Fig. 54); elytron subparallel-sided (Fig. 48), sternum VI with posterior margin straight (Fig. 55), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight (Fig. 55).
Description. Colour pattern (Figs. 30–32, 47–49) 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. 36, 54) with lateral margins narrower than distance between elytral humeri, posterior angles acute. Hypomeron ventrally rounded (Fig. 35, 53).
Male. Eye small (half as wide as distance between eyes) (Fig. 34), shorter than head (Fig. 35); antennomere IV 2x longer than wide (Fig. 33); pygidium almost 2x longer than sternum VIII greatest length, with lateral margins subparallel, posterior margin with median third sinuose, ventral keels absent (Figs. 38–40); sternum VIII moderately emarginated (Fig. 40); sternum IX slightly longer than aedeagus, arms of sternum IX of similar length, bearing stout subapical setae, with internal margins subparallel, apices truncate (Figs. 41–43); syntergite lacking transversal and medial sutures (Fig. 41); aedeagus with phallus divergent basally, then subparallel, basal projections of parameres contiguous, paramere narrowing towards apex, apex internally sinuose (Figs. 44, 46).
Female. Antenna filiform, antennomere III 2x longer than pedicel (Fig. 50); distance between antennal sockets wider than apical maxillary palpomere greatest width (Fig. 51); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin rounded (Fig. 53); elytron subparallel-sided (Fig. 47), sternum VI with posterior margin straight (Fig. 54), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight (Fig. 54, 56); ovipositor with proximal plates medially fused, longer than wide, weakly sclerotized (Fig. 57).
Etymology. The specific epithet desideratus is a name in apposition, and a Latin word for desired. Females of this new species were first caught in 2014, but males were only collected in 2017.
