29. Cyrea june Canepari and Gordon, new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body oval, convex. Dorsal surface with head alutaceous, dull, pronotum weakly alutaceous, weakly shiny, elytron smooth, shiny. Color yellow except pronotum with long, narrow, black basomedian macula extended 3/4 distance to anterior pronotal margin, macula with apical border entire; elytron with 3 black spots, discal spot on sutural margin anterior to middle of elytron short, narrow median anterior spot irregularly rectangular, apical spot irregularly rounded ( Fig. 158 ); ventral surface with prosternum, meso- and metaventrites dark brown; abdomen yellow except median 1/3 of ventrites 1-4 dark brown. Head punctures small, separated by a diameter or less, each puncture as large as an eye facet; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures larger than on pronotum, separated by 1 to 2 times a diameter; metaventral punctures about as large as on elytron, separated by about a diameter medially, larger and separated by less than a diameter in lateral 1/3. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin slightly curved, basal margin without trace of bordering line medially. Epipleuron wide, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/3 of prosternum, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward at apex, ventrite with sparse, long pubescence and small punctures sparse medially becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite depressed in median 1/3, apex medially emarginate with tuft of setae and tubercle on each side of emargination; 6th ventrite medially depressed, apex deeply, widely emarginate with lateral angle produced, rounded. Apical tergite finely, densely punctured, apex deeply emarginate. Genitalia with basal lobe longer than paramere, asymmetrical, sides slightly curved in basal 3/4, apical 1/ 4 abruptly bent to one side, apex obliquely truncate, outer angle acute; paramere Pem, strongly widened from base to emarginate apex, upper margin apically acute, lower margin rounded ( Fig. 159, 160, 161 ); sipho curved in basal 2/3, without visible alae, basal capsule with inner arm short, wide, apically truncate, outer arm wider and longer than inner arm, with accessory piece, basal border shallowly emarginate ( Fig. 162, 163 ).

Female. Similar to male except head with large, black median macula on frons narrowly surrounded by yellow. Genitalia with spermathecal capsule long, slender, cornu bulbous; bursal cap oval, with 3 sclerotized arms, apical strut long, base with short, slender projection posterior to short, enlarged area, remainder of strut slender, widened from base to apex ( Fig. 164 ).

Variation. Length 2.5 to 3.0 mm, width 1.8 to 2.4 mm. Pronotum with basomedian black macula rarely with apex slightly emarginate with yellow, discal spot on elytron slightly variable in size, many specimens with discal spot separated from sutural margin.

Type material. Holotype male; Brazil, Nova Teutonia , lat. 27 o 11’S, lon. 52 o 23’W, VIII-23-1945, F. Plaumann. ( USNM) .

Geographical distribution. Brazil.

Remarks. Cyrea june has a dorsal color pattern quite similar to that of C. emiliae , but the short, narrow discal spot on each elytron is characteristic of the former species. Male genitalia and abdomen with a tubercle and setal tuft on each side of the middle of the 5th abdominal ventrite are unusual and unique to C. june, but are similar to those of the thelma group in Serratitibia . Presence of tubercles on the male 5th ventrite is a primary defining character for members of Serratitibia Gordon and Canepari , but C. june lacks primary abdominal pores, and male genitalia are not of the type found in that genus.
