Pseudognypeta CAMERON 1923: 365 .

T y p e s p e c i e s Pseudognypeta picta CAMERON 1923: 366 (by monotypy).

D i a g n o s i s:Body.Mediumsized,length3.0- 3.7mm.Bodyslender,parallel-sided, convex, glossy ( Figs 6 and 11 ).

Head. Circular, temples broadly arcuately narrowed to hind angles; eyes strongly protruding from lateral contours of head; head with infraorbital ridge complete to maxillary insertion. Antennae long, strongly increased in width apically, extending to 2 of elytra.

Mouthparts. Maxilla ( Fig. 1 ) with lacinia subequal in length to galea; galea wide, rounded apically, subequal in width to lacinia at widest area; apex of galea with membranous lobe covered by short setae, base of apical lobe with patch of long setae; lacinia with inner margin of spines and long setae; maxillary palpus with 4 articles, article 1 very short, article 2 elongate, slightly widened apically, article 3 distinctly widened apically, slightly longer than article 2, article 4 elongate, about ¾ length of article 3. Labrum ( Fig. 4 ) transverse, narrowly and deeply emarginate apically and with characteristic arrangement of setae. Labium ( Fig. 2 ) with ligula relatively long and broad, about ¾ length of labial palpus 1; apex of ligula deeply bifid nearly to base; prementum with to moderately long medial setae, insertions of setae almost adjacent; median pseudopore field narrow and more or less linear, lateral pore field with a single setose pore, two asetose pores and about 15 small pseudopores; labial palpi 3-articled, article 1 elongate, parallel-sided, with 4 long setae, article 2 slightly narrower and about 3 times shorter than article 1, article 3 long, about 2 times longer than article 2. Mentum transverse ( Fig. 5 ), widest at base, apical margin weakly concave, anterior angles broadly rounded, 4 long setae on each side present. Mandibles curved towards apex, right mandible ( Fig. 3 ) with small median tooth at middle of inner margin, very weakly serrate in dorsal molar region, "velvety patch" area relatively small, composed of combination of anterior row of teeth and basal area of very fine spinules; condylar molar patch large, composed of numerous rounded lobelike structures.

Thorax. Pronotum quadrate, distinctly convex, glossy, widest in apical third, lateral sides gradually narrowed in straight line to rounded hind angles. Hypomera fully visible in lateral view. Mesocoxae moderately widely separated. Mesoventral process narrowly triangular, rounded at apex, extending to 2 of mesocoxae; metaventral process triangular in outline, broadly rounded at apex, extending to ½ of mesocoxae. Mesocoxal cavities margined posteriorly by fine bead.

Elytra. Quadrate, lateral sides straight, widest before base, postero-lateral angles straight.

Abdomen. Narrowed from base to apex, widest at base, tergites 3-5 weakly transversely impressed at base, impressions smooth, inpunctuate, sternites 3-5 not impressed at base. Legs elongate, metatarsus long, exceeding to 3/4 of metatibia; basal article of metatarsus short, shorter than article 2, articles 2-4 subequal in length, article 5 elongate, longer than articles 2-4 combined; tarsal formula 4-5-5.
