( Figs 257C View FIGURE 257 , 258E, G View FIGURE 258 )

Madecadryinus politus Olmi 2007c: 21 ; Azevedo et al. 2010: 885.

Description. ♀ ( Fig. 257C View FIGURE 257 ). Apterous; body length 1.2–2.1 mm. Head black, except clypeus and mandible testa- ceous; antenna testaceous; mesosoma black, except lateral margin of apparent pronotum and distal extremity of propodeal declivity testaceous; metasoma brown, except distal extremity testaceous; legs testaceous, except club of profemur brown, metacoxa partly brown and meso- and metafemur darkened. Antenna ( Fig.257C View FIGURE 257 ) clavate, thickened; antennomeres in following proportions: 9:2.5:1.5:3:3.5:3.5:3:3:3:7; antennomeres 1 and 10 longer than broad; antennomeres 3–9 broader than long or as long as broad (length/breadth ratio of antennomere 9 in lateral view: 3:3.5; antennomere 6 as broad as long: 3.5:3.5); antennomere 2 as long as broad; ADOs present in antennomeres 4– 10; antennal toruli contiguous with lateral margins of clypeus. Head rectangular in dorsal view ( Fig. 257C View FIGURE 257 ), broader than long (21.5:19), shiny, covered with short and fine setae, finely punctate, unsculptured among punctures; vertex of head flat; frons very convex ( Fig. 258E View FIGURE 258 ); eye ( Fig. 258E View FIGURE 258 ) small, much shorter than head (4: 19 in dorsal view); ocelli absent; occipital carina distinct, complete on dorsal region of head, but incomplete on lateral regions of head; frontal line absent; clypeus with ventral margin rounded; temple very long, almost 3 × as long as eye (11:4); subocular sulcus absent. Palpal formula 2/2. Propleuron apparently mobile and articulated, hidden under apparent pronotum. Remaining regions of mesosoma completely fused with no sutures separating fused regions; laterally in- complete sutures visible (suture between apparent pronotum and mesothorax and meso-metapleural suture); above two sutures incomplete and partly visible on lateral regions of mesosoma. Mesosoma ( Fig. 257C View FIGURE 257 ) 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 visible, except suture separating dorsal region from lateral regions (suture incomplete, being absent in anterior third of dorsal region (probably corresponding to pronotum)) ( Fig. 257C View FIGURE 257 ); propodeal declivity completely surrounded by strong keel separating it from metapectal-propodeal disc and from lateral regions of mesosoma; anterior dorsal region and posterior inclined region completely unsculptured, except few transverse striae near apex of posterior region. Protarsomeres in following proportions: 8:2:2:6:9. Protarsomere 3 produced into hook. Enlarged claw ( Fig. 258G View FIGURE 258 ) with three small teeth, 10 bristles and many setae on outer side. Protarsomere 5 ( Fig. 258G View FIGURE 258 ) with two rows of 3 + 10 lamellae; apex with four lamellae. Tibial spurs 1/0/1.

♂. Unknown.
