Diagnosis.-

Paragongylopus (Planoparagongylopus) abramovi sp. n. is similar to Paragongylopus (Planoparagongylopus) nabanheensis sp. n., but can be distinguished by square mesonotum and distinct elevations on legs.

Description.-

Female (Figs 5-6, 19-21): Small size. Body flattened and stout. General color of body and legs grayish brown. Head oval in dorsal view, dorsoventrally flattened, with minute pits. Vertex flat and unarmed. Occiput flat. Median longitudinal furrow indistinct. Compound eyes small and oval, its length about three times that of genae. Antennae short, with three distinct segments; scapus oval in dorsal view, more or less triangle-shaped in cross section, larger than compound eyes, about four times longer than pedicellus; pedicellus minute and indistinct, knob-like, smaller than compound eyes; third segment generally cylindrical, apices blunt, tapering basally, about three times longer than scapus, inner margin elevated medially, first half of inner margin with minute spine-like bristles. Thorax with minute pits. Pronotum trapezoidal, expanded posteriorly, wider than head; anterior margin weakly incurved, posterior margin truncate, anterolateral angles weakly tuberculate; transverse sulcus short, placed after middle area, longitudinal sulcus indistinct. Mesonotum square, as long as mesofemora; median longitudinal carina distinct. Metanotum rectangular, wider than pronotum, wider than long, parallel to mesonotum, median longitudinal carina distinct. Abdomen flattened, tapering posteriorly. Distinctly carinate mediolongitudinally. Wrinkled and pitted, also with a very few small granules. Median segment narrow, wider than long. Second and third tergites parallel to mesonotum and metanotum, fourth tergum to anal segment not wider than second tergum. Seventh sternum lacking noticeable praeopercular organ. Eighth tergum longer than ninth tergum. Anal segment longer than ninth tergum, shorter than eighth tergum, medially constricted posteriorly, posterior margin with a small emargination.
