( Figs 255B , 256C, D )

Apogonatopus madagascariensis Olmi 2007c: 13 ; Azevedo et al. 2010: 884.

Description. ♀ ( Figs 255B, C ). Apterous; body length 2.0 mm. Head black, except clypeus and mandible tes- taceous; antenna testaceous; mesosoma black, except lateral margin of apparent pronotum and apex of propodeal declivity testaceous; metasoma brown, except distal third testaceous; legs testaceous, except metacoxa almost completely brown. Antenna clavate, slender; antennomeres in following proportions: 8:3.5:4:5:5.5:5.5:5.5:5.5:5:10; antennomeres longer than broad; length/breadth ratio of antennomere 9 in lateral view: 5:3; antennomere 2 longer than broad; ADOs present in antennomeres 3–10; antennal toruli contiguous with lateral margins of clypeus. Head spheroidal in dorsal view, slightly broader than long (20:17), shiny, covered with short and fine setae, finely punctate, unsculptured among punctures; vertex of head convex; eye small, much shorter than head (5: 17 in dorsal view); ocelli absent; occipital carina distinct, complete on dorsal region of head, incomplete on lateral regions; frontal line absent; clypeus humped, with ventral margin rounded; temple very long, less than twice as long as eye (7:5); subocular sulcus absent (short slight track present). Palpal formula 4/3. Propleuron apparently mobile and articu- lated, hidden under apparent pronotum. Remaining regions of mesosoma almost completely fused, with transverse suture separating mesosoma in anterior and posterior part (laterally suture separating two above parts formed by meso-metapleural suture); anterior part of mesosoma composed of pronotum + mesothorax; posterior part of mesosoma composed of metapectal-propodeal disc + propodeal declivity; pronotum + mesothorax completely shiny and unsculptured. Mesothoracic spiracles present. In pronotum + mesothorax no dorsal sutures visible (laterally two incomplete sutures present, first one separating pronotum from mesopleuron and second one corresponding to epicnemial sulcus); suture between pronotum + mesothorax and metapectal-propodeal disc with two small pointed structures (metathoracic spiracles) situated on sides of dorsal part ( Fig. 255B ); posterior part of mesosoma dorsally divided into two regions, first one dorsal and composed of metanotum + metapectal-propodeal disc, second one posterior and inclined corresponding to propodeal declivity; propodeal declivity completely surrounded by keel separating this area from metapectal-propodeal disc and metapleuron (keel laterally with two small pointed structures per side ( Fig. 255B ); metapectal-propodeal disc laterally with two prominent propodeal spiracles ( Fig. 255B ). Metapectal-propodeal disc composed of completely fused sclerites, not showing any dorsal or lateral suture, completely smooth, shiny, with few short setae, unsculptured, except few lateral rugosities situated near meso- and metacoxa and two long distinct lateral longitudinal sutures joining lateral pointed structures of metapectal-propodeal disc to three spiracles (mesothoracic, metathoracic, propodeal) and separating metapectal-propodeal disc + metanotum from metapleura and mesonotum from mesopleura ( Figs 255C , 256C ). Propodeal declivity unsculptured, except few dorsal transverse striae situated near apex. Protarsomeres in following proportions: 12:3:2:6.5:9. Protarsomere 3 produced into hook. Enlarged claw ( Fig. 256D ) with two small subapical and medial teeth and one row of eight slender lamellae. Protarsomere 5 ( Fig. 256D ) with two rows of 2 + 8 lamellae; apex with five lamellae. Tibial spurs 1/0/1.
