NOTES ON ARADIDAE, III — KORMILEV 255 



Mezira carioca, new species 



Figure 7 



Female. — Elongate ovate, lateral borders parallel, gently narrow- 

 ing anteriorly and posteriorly; body covered with rough setigerous 

 granulation, with short, erect setae. 



Head shorter than width across eyes (28:32); anterior process with 

 sides subparallel, rounded anteriorly, and excavated at tip, reaching 

 to, or almost to, tip of first antennal segment. Antenniferous tuber- 

 cles pointed, slightly divergent, reaching to basal third of first antennal 

 segment. Eyes exserted. Postocular tubercles strong, pointed, pro- 

 jecting laterally far beyond outer margin of each eye. Infraocular 

 carinae moderately high, crenulate; vertex with V-shaped rows 

 of granulae. Antennae very short, slender, less than one and a half 

 times length of head (39:28); proportions of antennal segments 

 12:7.5:12:7.5. Rostrum reaches to base of rostral sulcus. 



Pronotum less than half as long as width across humeri (32 : (58) : 67) . 

 Collum slender; anterolateral angles roundly expanded, slightly raised 

 laterally, crenulate; lateral borders slightly cut out in middle, slightly 

 convex at humeri; hind border also slightly excavated at middle, 

 Foredisc with four (2 + 2) oblique, granulate ridges; hind disc with 

 scattered, rough, setigerous granulations. 



Scutellum shorter than basal width (25:35), typical of Neotropical 

 Mezira species. 



Hemelytra short, reaching hind border of tergum VI (9); baso- 

 lateral borders slightly reflexed; apical border of the corium and apex 

 of apical angle very feebly rounded. 



Abdomen longer than wide (95:74), elongate ovate, almost parallel- 

 sided along middle, tapering in gentle curve posteriorly. Connexivum 

 covered with setigerous granulation; connexiva with postero-exterior 

 angles not protruding; lobes of VIII relatively large; rounded, reaching 

 to middle of IX, latter cut out at tip. All spiracles ventral, placed 

 far from outer margin. 



CoLOR.^ — Uniformly ferrugineous. 



Measurements. — Length 6.33. Width of pronotum 2.23 mm. 

 Width of abdomen 2.47 mm. 



HoLOTYPE. — Female, Rio de Janeiro, Brazil, Drake Collection 

 (USNM type 65799). 



Remarks. — M. carioca is allied to M. saltensis Kormilev, but it 

 differs from the latter by the following characteristics: much smaller 

 size; lateral borders of pronotum less excavated; anterior process of 

 head relatively shorter; lobes of VIII relatively larger, reaching to 

 middle of IX (only to basal fourth of IX in M. saltensis) ; anterolateral 

 angles of pronotum more rounded and produced farther forward.
