Diagnosis. Elytron dark-brown ( Figs. 30 View FIGURES30–46 , 48 View FIGURES 47–57 ). Male with eye small (half as wide as distance between eyes) ( Fig. 34 View FIGURES30–46 ); 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 View FIGURES30–46 ); sternum IX slightly longer than aedeagus, arms of similar length, bearing stout subapical setae, with internal margins subparallel, apices truncate ( Figs. 41– 43 View FIGURES30–46 ). Female with antenna filiform ( Fig. 51 View FIGURES 47–57 ); distance between antennal sockets wider than apical maxillary palpomere greatest width ( Fig. 52 View FIGURES 47–57 ); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin rounded ( Fig. 54 View FIGURES 47–57 ); elytron subparallel-sided ( Fig. 48 View FIGURES 47–57 ), sternum VI with posterior margin straight ( Fig. 55 View FIGURES 47–57 ), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 55 View FIGURES 47–57 ).

Description. Colour pattern ( Figs. 30–32 View FIGURES30–46 , 47–49 View FIGURES 47–57 ) 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 View FIGURES30–46 , 54 View FIGURES 47–57 ) with lateral margins narrower than distance between elytral humeri, posterior angles acute. Hypomeron ventrally rounded ( Fig. 35 View FIGURES30–46 , 53 View FIGURES 47–57 ).

Male. Eye small (half as wide as distance between eyes) ( Fig. 34 View FIGURES30–46 ), shorter than head ( Fig. 35 View FIGURES30–46 ); antennomere IV 2x longer than wide ( Fig. 33 View FIGURES30–46 ); 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 View FIGURES30–46 ); sternum VIII moderately emarginated ( Fig. 40 View FIGURES30–46 ); 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 View FIGURES30–46 ); syntergite lacking transversal and medial sutures ( Fig. 41 View FIGURES30–46 ); aedeagus with phallus divergent basally, then subparallel, basal projections of parameres contiguous, paramere narrowing towards apex, apex internally sinuose ( Figs. 44, 46 View FIGURES30–46 ).

Female. Antenna filiform, antennomere III 2x longer than pedicel ( Fig. 50 View FIGURES 47–57 ); distance between antennal sockets wider than apical maxillary palpomere greatest width ( Fig. 51 View FIGURES 47–57 ); pronotum widest at posterior angles, narrower than elytral humeral distance, anterior margin rounded ( Fig. 53 View FIGURES 47–57 ); elytron subparallel-sided ( Fig. 47 View FIGURES 47–57 ), sternum VI with posterior margin straight ( Fig. 54 View FIGURES 47–57 ), sternum and tergum VII connected by membrane; sternum VIII as sclerotized as VII, with posterior margin straight ( Fig. 54, 56 View FIGURES 47–57 ); ovipositor with proximal plates medially fused, longer than wide, weakly sclerotized ( Fig. 57 View FIGURES 47–57 ).

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.
