( Figs 254A, B , 255A , 256A, B )

Apogonatopus edaphicus Olmi 2007c: 11 ; Azevedo et al. 2010: 884.

Description. ♀ ( Figs 254A, B , 255A ).Apterous; body length 1.9–2.2 mm. Head black, except clypeus and mandible testaceous; 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 of holotype in following proportions: 10:4:5:6:6:6:6:6:6:10; antennomeres longer than broad; length/breadth ratio of antennomere 9 in lateral view: 6:3; antennomere 2 longer than broad; ADOs present in antennomeres 3–10; antennal toruli contiguous with lateral margins of clypeus. Head spheroidal in dorsal view ( Figs 254B , 255A ), slightly longer than broad (28:23), smooth, shiny, covered with short and fine setae, finely punctate, unsculptured among punctures; vertex of head convex ( Fig. 255A ); eyes small, much shorter than head (7: 28 in dorsal view); ocelli absent; occipital carina distinct, complete on dorsal region of head, incomplete on lateral regions; frontal line absent; mandible with four irregular teeth; clypeus with ventral margin rounded; temple very long, less than twice as long as eye (12:7) ( Fig. 254B ); subocular sulcus absent (short slight track present). Palpal formula 2/2. Propleuron apparently mobile and articulated, hidden under apparent pronotum. Remaining regions of mesosoma almost completely fused, with transverse suture separating mesosoma in anterior and posterior part (suture laterally formed by meso-metapleural suture); anterior part of mesosoma composed of pronotum + mesothorax; posterior part of mesosoma composed of metapectal-propodeal disc and 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. 254A ); 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 apophyses per side ( Fig. 254A ); metapectal-propodeal disc laterally with two prominent propodeal spiracles ( Fig. 254A ). Metapectal-propodeal disc composed of completely fused sclerites, not showing any dorsal or lateral suture, completely shiny, with few short setae, unsculptured, except few lateral rugosities situated near meso- and metacoxa and two very short distinct lateral longitudinal sutures leaving from lateral pointed apophyses of metapectal-propodeal disc and directed towards propodeal spiracles, not reaching them ( Fig. 256A ). Propodeal declivity unsculptured, except few dorsal transverse striae situated near apex. Protarsomeres in following proportions: 11:3:2.5:7:9. Protarsomere 3 produced into hook. Enlarged claw of holotype ( Fig. 256B ) with four small subapical and medial teeth and one row of six slender lamellae. Protarsomere 5 of holotype ( Fig. 256B ) with two rows of 4 + 9 lamellae; apex with five lamellae. Tibial spurs 1/0/1.
