Genus Ecomorypora CAMERON 1945 ( Figs 1-5 , 6-7, 12, 16)

Ecomorypora CAMERON 1945: 165 .

T y p e s p e c i e s Myrmecopora granulata BROUN 1912: 398 (by monotypy).

D i a g n o s i s: Body. Medium sized, length 4.0- 5.5 mm. Body slender, parallel-sided, convex, densely pubescent (Figs 6, 7, 12, 16).

Head. Circular, temples broadly arcuately narrowed to hind angles; eyes moderately protruding from lateral contours of head; head without infraorbital ridge. Antennae long and slender, very weakly increased in width apically, extending to 2-3/4 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; 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 short, about 1/3 length of article 3. Labrum ( Fig. 4 ) transverse, widely and deeply emar- ginate apically and with characteristic arrangement of setae. Labium ( Fig. 2 ) with ligula relatively long and slender, about ¾ length of labial palpus 1; apex of ligula bifid in anterior 1/3; prementum with to moderately long medial setae, separation of medial setae 3 times width of setal pore; median pseudopore field relatively wide and more or less linear, composed of numerous pseudopores, lateral pore field with a single setose pore, two asetose pores and 5-6 small pseudopores; labial palpi 3-articled, article 1 elongate, with 5 long setae, article 2 slightly shorter and distinctly narrower than article 1, article 3 subequal in length to article 2, with band of poorly sclerotized region, below apex containing 3 sensory pores. Mentum transverse ( Fig. 5 ), widest at base, apical margin weakly concave, anterior angles broadly rounded, 6 long setae on each side present. Mandibles curved towards apex, right mandible ( Fig. 3 ) with relatively large median tooth at middle of inner margin, moderately 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.

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 very narrowly separated. Meso- and metaventral processes very short, scarcely extending to 1/6 of mesocoxae; mesoventral process with median longitudinal ridge. Mesocoxal cavities margined posteriorly by fine bead.

Elytra. Elongate, lateral sides straight, widest before base, postero-lateral angles weakly sinuate.

Abdomen. Parallel-sided, widest at level of tergites V and VI; tergites III-VI distinctly transversely impressed at base, impressions punctuate; sternites 3-5 not impressed at base. Legs elongate, metatarsus long, exceeding to 3/4 of metatibia; basal article of metatarsus long, subequal in length to articles 2 and 3 combined, articles 2-4 relatively short, subequal in length, article 5 elongate, longer than articles 3-4 combined and subequal in length to 1; tarsal formula 4-5-5.
