Ambonoides retinoides OPITZ nov. sp.

( Figs 1-15 , 62 , 87-92 , 109, 110 , 143-145 , 175 )

Holotype: ♂. Nova Teutonia, SC, Brasil, XI.1966, F. Plaumann ( FSCA).

Paratypes: Four specimens. Brazil: Santa Catarina: 29-XI-1940, 27°11' La., 52°23' Lo, Fritz Plaumann ( AMNH, 2) ; Rio Grande do Sul, Porto Alegre, 4-XI-1953, Pe. Buck ( WOPC, 1). Uruguay: Approx. 6 km SE Melo, Dept. Cerro Largo, 25-27-II-1963, John K. Bouseman ( WOPC, 1) .

Diagnosis: The members of this species resemble superficially those of Ambonoides caraguata . However, in specimens of A. retinoides the legs are entirely black, whereas in A. caraguata specimens the femora are partially flavotestaceous.

Description: Size: Length 8.5 mm; width 2.8 mm. Form: As in Fig. 145 . Color: Cranium mostly black, lower frons and clypeus flavotestaceous; pronotum mostly black, upper sides, anterior margin, and small anterior wedged-shaped macula flavotestaceous; elytral disc mostly black, with midelytral testaceous fascia. Head: Antennal capitulum very long ( Figs. 62 , 90 ), each capitular antennomeres as long as combined length funicular antennomeres; antennal carina very prominent; EW/FW 12/16. Thorax: Pronotal anterior margin not projected at middle, sides of disc depressed; side margin of disc rounded ( Fig. 6 ); PW/PL 45/45; elytra subrectangulate, sides sharply deflexed; EL/EW 210/43. Abdomen: Male pygidium incised at distal margin; aedeagus as in Figs. 109, 110 . Female mesodermal reproductive organs ( Fig. 143 ): Spermathecal capsule slightly sclerotized; spermathecal gland attached to apex of capsule; bursa copulatrix saccular; bursal sclerite present ( Fig. 144 ).

Natural history: Specimens were collected during May and November.

Variation: Size: Length 8.0-8.5 mm; width 2.0-2.8 mm. The elytra may be entirely flavotestaceous, or flavotestaceous in basal half and black in remainder.

Distribution ( Fig. 175 ): This species is known from Uruguay and southeastern Brazil.

Etymology: The trivial name retinoides is a compound Latin name derived from rete (= net) and the suffix – oides (= likeness). I refer to the network-like property of the surface of the elytral disc.
