Madecadryinus relictus Olmi 2007c: 26  ; Azevedo et al. 2010: 885.

Description. ♀ ( Figs 257D, EView FIGURE 257, 260A, BView FIGURE 260). Apterous; body length 1.6–2.0 mm. Head black, except clypeus and mandible testaceous; antenna testaceous; mesosoma black, except lateral margin of apparent pronotum testaceous; apparent mesothorax black, except small region near mesocoxa testaceous; metasoma brown, except distal half testaceous; legs testaceous. Antenna ( Figs 257D, EView FIGURE 257, 260A, BView FIGURE 260) clavate, thickened; antennomeres of holotype in following proportions: 7:2:2:2.5:2.5:2.5:2.5:2.5:2.5:7; antennomeres 1 and 10 longer than broad; antennomeres 3–9 broader than long (length/breadth ratio of antennomere 9 in lateral view: 3.5:4.5; in dorsal view: 2:4; antennomere 6 broader than long: 3.5:2.5); antennomere 2 approximately as long as broad; ADOs present in antennomeres 4–10; antennal toruli contiguous with lateral margins of clypeus. Head rectangular in dorsal view ( Figs 257DView FIGURE 257, 260AView FIGURE 260), broader than long (23:18), shiny, covered with short and fine setae, finely punctate, unsculptured among punctures; vertex of head flat; frons very convex ( Figs 257EView FIGURE 257, 260BView FIGURE 260); eye very small, much shorter than head (3: 17 in dorsal view); ocelli absent; occipital carina distinct, complete on dorsal region of head, incomplete on lateral regions of head; frontal line absent; mandible with three teeth; clypeus with ventral margin rounded; temple very long, almost 4 × as long as eye (11:3) ( Fig. 260AView FIGURE 260); subocular sulcus absent. Palpal formula 2/2. Propleuron apparently mobile and articulated, hidden under apparent pronotum. Remaining regions of mesosoma ( Figs 257D, EView FIGURE 257, 260A, BView FIGURE 260) completely fused with no sutures separating fused regions; laterally two incomplete sutures visible (suture between apparent pronotum and mesothorax and meso-metapleural suture); above two sutures incomplete and only partly visible on lateral regions of mesosoma (upper third of meso-metapleural suture absent). Mesosoma ( Figs 257D, EView FIGURE 257, 260A, BView FIGURE 260) shiny, covered with fine and short setae, finely punctate, unsculptured among punctures; mesosoma cylindric and divided into two regions (anterior flat dorsal region (corresponding to pronotum, mesonotum, metanotum and metapectal-propodeal disc) and posterior inclined region (corresponding to propodeal declivity)); in anterior dorsal region, no sutures dorsally visible, except suture ( Fig. 261AView FIGURE 261) separating dorsal region from lateral regions (suture incomplete, being absent in anterior third of dorsal region (probably corresponding to pronotum) and from propodeal ocelli and lateral corners of keel surrounding posterior inclined region of mesosoma); posterior inclined region completely surrounded by strong keel separating it from anterior dorsal region and from lateral regions of mesosoma; posterior inclined region completely unsculptured, except few transverse striae near apex of posterior region. Protarsomeres in following proportions: 7:2:2:4.5:7.5. Protarsomere 3 produced into hook. Enlarged claw of holotype ( Fig. 261BView FIGURE 261) without subapical teeth (tracks of small teeth visible), with three proximal bristles and many setae on outer side; enlarged claw of paratype from Madagascar, 18°10.17’S 47°16.55’E, with long row of 11 bristles and three small teeth. Protarsomere 5 of holotype ( Fig. 261BView FIGURE 261) with two rows of 2 + 9 lamellae (in paratype from Madagascar, 18°10.17’S 47°16.55’E, protarsomere 5 with two rows of 3 + 10 lamellae).Apex of protarsomere 5 with five lamellae. Tibial spurs 1/0/1.

♂ ( Figs 260C, DView FIGURE 260, 261CView FIGURE 261, 262AView FIGURE 262). Fully winged; body length 1.6 mm. Head black, except mandible testaceous (with teeth dark) and clypeus testaceous-dark; antenna testaceous-darkened; mesosoma black; metasoma brown; legs yellow, except metacoxa and club of metafemur brown. Antenna filiform, very slender and long, much longer than body ( Fig. 260CView FIGURE 260); antennomeres in following proportions: 5.5:4.5:9:11:10:10.5:10:10:10:10. Head convex ( Fig. 260DView FIGURE 260), shiny, unsculpured; occiput very concave, unsculptured; frontal line absent; central area of frons with slight short median longitudinal furrow; occipital carina complete; ocelli small ( Figs 260CView FIGURE 260, 262AView FIGURE 262); POL = 4.5; OL = 2.5; OOL = 3.5; minimum distance from eyes to occipital carina shorter than OL (2:2.5); TL = 4.5; lateral ocelli touching occipital carina; temples very long, shorter than eyes (4.5:7); clypeus with short median longitudinal keel; mandible with four irregular teeth. Palpal formula 6/3. Mesoscutum dull, completely granulate. Notauli complete, posteriorly separated; minimum distance between notauli twice as long as greatest breadth of lateral ocelli (4:2). Mesoscutellum and metanotum shiny, unsculptured. Epicnemium exposed. Metapectal-propodeal disc and propo-deal declivity reticulate rugose, with areolae at least partly as large as tegulae. Forewing with slight dark transverse band; distal part of 2r-rs&Rs vein longer than proximal part (15:10); 2R1 cell open. Hind wing hyaline, without dark transverse band. Paramere ( Fig. 261CView FIGURE 261) without inner apical and pointed expansion; basivolsella with apex parallel to distivolsella ( Fig. 261CView FIGURE 261). Tibial spurs 1/1/2.
