6. Prodilis katrina Gordon and Hanley , new species

Description. Male holotype. Length 2.5 mm, width 2.0 mm; body oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface shiny except elytron with faint trace of microsculpture. Color bluish black ( Fig. 345 ); head with basal 1/3 reddish yellow, anterior 2/3 yellow ( Fig. 347 ); pronotum reddish yellow, lateral 1/8 yellow; elytral lateral margin reddish brown; antenna, mouthparts, legs yellow; prosternum, epipleuron reddish brown; remainder of ventral surface black; abdomen with basal ventrite dark brown, median portion of ventrites 2, 3 dark brown, remainder of abdomen yellow. Head punctures small, separated by a diameter or less; pronotal punctures as large as on head, separated by less than 3 times a diameter; elytral punctures slightly larger than on pronotum, separated by less than twice a diameter; prosternal punctures as large as on elytron; mesosternal punctures larger than on prosternum, separated by less than a diameter; metasternal punctures as slightly smaller than on mesosternum, separated by a diameter or less; abdomen with punctures on ventrites 1– 3 smaller than on metasternum, separated by less than twice a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons slightly widened from vertex to clypeus, nearly parallel sided, slightly wider than eye measured at vertex; eye canthus short; apical maxillary palpomere short, strongly widened from base to apex. Pronotum widest at middle, reflexed lateral margin wide, of equal width from base to apex. Epipleuron flat, wide in basal ½, wider than pronotal hypomeron. Prosternum longer than wide, longer than mesosternum, apical margin arcuate, lateral carina slender, short, extended just anterior to coxa. Postcoxal line on ventrite 1 long, rounded, extended 3/4 distance to apical margin of ventrite ( Fig. 346 ). Apex of ventrite 5 slightly arcuate. Genitalia with basal lobe slightly longer than paramere, slender, slightly narrowed from base to deeply emarginate apex; paramere slen- der, weakly curved, about equal in width from base to rounded apex, without marginal serrations ( Fig. 348, 349 ); sipho slender, abruptly bent at apical 1/8 ( Fig. 350 ).

Female. Similar to male except head entirely reddish yellow, genitalia with spermathecal capsule short, basal ½ large, anterior ½ small, slender, cornu apically rounded.

Variation. Length 2.3 mm, width 1.8 mm.

Type material. Holotype male; BRAZIL: Rio de Janeiro, Conceicao de Macabu , IX.1978, M. Alvarenga. ( CMNH) . Paratype; 1, BRAZIL: Rio de Janeiro, Murundu Campos , VIII.1978, M. Alvarenga. ( CMNH) .

Remarks. This species is similar to P. erika but has an entirely reddish yellow pronotum; head basally reddish yellow with yellow anterior portion; and basal lobe of male genitalia longer than paramere. Both species resemble Prodilis volgus in color pattern and may easily be confused with that species. See remarks under P. volgus .
