( Figs 114B View FIGURE 114 , 116 View FIGURE 116 , 117A View FIGURE 117 )

Diagnosis. ♂ of Bocchus with mesoscutum reticulate rugose ( Fig. 117A View FIGURE 117 ); notauli incomplete, reaching approxi- mately 0.5–0.8 × length of mesoscutum; propodeal declivity with median area at least partly shiny, unsculptured; apex of basivolsella with one subdistal inner pointed apophysis ( Fig. 114B View FIGURE 114 ).

Description. ♂ ( Figs 116 View FIGURE 116 , 117A View FIGURE 117 ). Fully winged; body length 2.2–2.9 mm. Head black, except mandible testaceous; antenna ferruginous; mesosoma black; metasoma brown; legs brown, except procoxa and tarsi testaceous. Antenna filiform; antennomeres in following proportions: 11:6:7:7:7:7:7:6:6:8; antennomere 8 less than 3 × as long as broad (6:3). Head ( Fig. 116C View FIGURE 116 ) convex, dull, covered with short setae, granulate and reticulate rugose; frontal line complete; occipital carina complete; POL = 6; OL = 3; OOL = 8; OPL = 6; TL = 3; greatest breadth of lateral ocelli longer than OL (4:3). Mesoscutum ( Fig. 116A View FIGURE 116 ), mesoscutellum and metanotum dull, completely strongly reticulate rugose. Notauli incomplete, reaching approximately 0.5 × length of mesoscutum (in specimens from Madagascar, 12°13.97’ S 49°21.99’E, notauli reaching about 0.8 × length of mesoscutum). Mesopleuron dull, strongly reticulate rugose. Metapleuron dull, sculptured by numerous strong transverse keels. Metapectal-propodeal disc with strong transverse posterior keel, dull, reticulate rugose; propodeal declivity with two complete longitudinal keels, lateral areas completely reticulate rugose and median area partly shiny and unsculptured. In paratype from Madagascar, 22°54.22’S 43°28.53’E, median area of propodeal declivity almost completely reticulate rugose, with unsculptured central area very small. Forewing ( Fig. 116D View FIGURE 116 ) hyaline, without dark transverse bands; 2r-rs&Rs vein with distinct separation between distal and proximal part; distal part of 2r-rs&Rs vein slightly shorter than proximal part (10:11). Apex of basivolsella with one subdistal inner pointed apophysis ( Fig. 114B View FIGURE 114 ). Tibial spurs 1/1/2.

Hosts. Unknown.

Distribution. Madagascar.

Etymology. The Latin adjective ruvidus (= rugose) refers to the rugose sculpture of head, mesoscutum, mesoscutellum and metanotum.

Remarks. In the paratype from Madagascar, 22°54.22’S 43°28.53’E, the median area of the propodeal declivity is almost completely reticulate rugose, with a very small unsculptured central area, with the result that it may be confused with Bocchus johanssoni Olmi, Copeland & Guglielmino , that has the median area completely reticulate rugose. However, in B. johanssoni the antenna is more slender than in B. ruvidus (antennomere 8 much more than twice as long as broad (8:3) in B. johanssoni ; about twice as long as broad (6:3) in B. ruvidus ).
