Abiliella Peracchi, 1964

Abiliella Peracchi 1964: 119 . Type species: Abiliella fasciata Peracchi, 1964 . By original designation. Opitz 2012: 4 .

Diagnosis. The members of this genus resemble those of Ochracea Opitz , but in Abiliella specimens, the pronotum is oblong, the pronotal lateral margins show a well-developed tubercle, the last maxillary and labial palpomeres are securiform, the elytral disc shows eight striae of asetiferous punctures, and the spicular apodemes are fused at their posterior extremity. By contrast, in Ochracea specimens the pronotum is slightly transverse, the pronotal lateral margins are without a tubercle, the maxillary and labial terminal palpomeres are subsecuriform, the elytral disc is devoid of asetiferous punctures, and the spicular apodemes are fused at their middle.

Description. This genus was described and illustrated by Peracchi (1964) and redescribed and illustrated by Opitz (2012) . In the latter publication, figure 1j indicates that the spicular apodemes are not fused. I have ascertained that the apodemes do fuse at their posterior limits.

Distribution. This genus is known from Bolivia, Brazil, and Uruguay.

Abiliella albosutura Opitz , new species ( Figs. 1, 8 View Figs , 26 View Figs , 33 View Figs , 39 View Fig , 40 View Fig )

Holotype. ♂. BRAZIL: Rondonia, 62 km SW Ariquenes, Fzda, Rancho Grande, XI-19-1994. A second label reads: Collectors : C. W. & L. B. O’ Brien. ( FSCA).

Paratype. One specimen. BOLIVIA: Santa Cruz, Est. Experimental Gral. Saavedra, XI-1973, L. Stange-C. Porter ( IMLA) .

Diagnosis. The narrow frons will distinguish the members of this species from congeners, whose frons are considerably wider (compare Figs. 26 and 27 View Figs ).

Description. Size: Length 6.0 mm; width 2.0 mm. Form: As in Fig. 26 View Figs . Color: Cranium, pronotum, pterothorax, and abdomen dark brown; legs bicolorous, femora and tibiae predominantly yellow, infuscated at extremities; elytral disc predominantly brown, sutural margin broadly yellow, epipleural margin yellow near apex. Head: Cranium coarsely punctate, frons much narrower than width of eye (FW/EW = 12/28); funicular antennomeres filiform, antennomeres 9 and 10 subtriangular, antennomere 11 subovoid ( Fig. 1 View Figs ). Thorax: Pronotum oblong ( Fig. 8 View Figs ) (PL/PW = 80/60), coarsely punctate, without tubercle at sides; elytral disc sculptured with 8 asetiferously punctate striae that end at elytral apical 2/3 (EL/EW = 125/28), interstitial spaces large and smooth. Abdomen: Male pygidium slightly incised at middle of anterior margin. Aedeagus: Phallobase very lightly sclerotized; lobes welldeveloped; slightly fimbriate; phallobasic rod linear; phallobasic struts fused to phallobasic apodeme; phallic apex large; phallic plates broad ( Fig. 33 View Figs ).

Variation. The elytral disc is light testaceous in the paratype.

Natural History. The type specimens were collected in November.

Distribution. This species is known from Santa Cruz, Bolivia and from Rondonia, Brazil ( Fig. 39 View Fig ).

Etymology. The specific epithet albosutura is a Latin compound name that stems from albus

(= white) and sutura (= seam). I refer to the coloration of the sutural margin.

Abiliella fasciata Peracchi, 1964 ( Figs. 2, 9, 15 View Figs , 27 View Figs , 34 View Figs , 39 View Fig , 40 View Fig )

Abiliella fasciata Peracchi, 1964: 120 . Holotype. ♂. Corcovado , Rio de Janeiro, Estado de Guanabara, BRASIL, 10-IX-1959, Alvarenga & Seabra col. (CASB).

Paratypes. Three specimens. BRASIL: Rio de Janeiro: 10-X-1958, Alvarenga & Seabra ( CASB, 1) . BRASIL: Rio de Janeiro: 23-X-1958, Alvarenga & Seabra ( CASB, 1) . BRASIL: Rio de Janeiro: 16- X-1958, Alvarenga & Seabra ( CASB, 1) . Allotype. BRASIL: Rio de Janeiro: 9-XI-1958, Alvarenga & Seabra ( CASB, 1) .

Diagnosis. The mid-elytral testaceous fascia will distinguish the members of this species from congeners.

Description. This species was described and illustrated by Peracchi (1964). Figs. 2, 9, 15 View Figs , 27 View Figs , and 34, included herein, refer to this species.

Distribution. This species is known from Brazil and Uruguay ( Fig. 39 View Fig ). I examined the following specimens: BRASIL: Rio de Janeiro, Corcovado, I-1962, Seabra & Alvarenga. BRAZIL: Maranhão: Lago Verde, 27-IV-1981, W. Overal. URUGUAY: Rocha: 15 km S Rocha, 4-II-1989, C.W. & L O’ Brien & Wibmer. Specimens are deposited in CASB, FSCA, JNRC, MPEG, and WOPC.

Holotype. ♂. ( BRASIL): Imbituba, SC ( Praia do Rosa ), 01.I.2001, R. Araujo coll. ( MCNZ).

BRASIL: São Paulo: Barueri , XII.1965, K Lenko ( WOPC, 1) .

Diagnosis. Specimens of this species resemble superficially those of A. albosutura , from which they may be distinguished by not having the sutural margin testaceous. Also, the frons of A. galbina ( Fig. 18 View Figs ) is wider than that of A. albosutura .

Description. Size: Length 7.0 mm; width 2.0 mm. Form: As in Fig. 28 View Figs . Color: Cranium dark brown, pronotum red-brown, pterothorax, legs, and abdomen dark brown; elytral disc predominantly dark brown, epipleural margin yellow. Head: Cranium coarsely punctate, frons narrower than width

of eye (FW/EW = 25/30) ( Figs. 18, 20, 21 View Figs ); funicular antennomeres filiform ( Fig. 3 View Figs ), antennomeres 9 and 10 triangular, antennomere 11 subovoid ( Fig. 19 View Figs ). Thorax: Pronotum oblong ( Fig. 14 View Figs ) (PL/PW = 85/74), coarsely punctate, with shallow tubercles at sides; elytral disc ( Figs. 22, 23 View Figs ) sculptured with 8 asetiferously punctate striae that end near elytral apex (EL/EW = 190/70), elytral interstitial spaces large and smooth; legs as in Figs. 24, 25 View Figs . Abdomen: Male pygidium slightly truncate. Aedeagus: Phallobase very lightly sclerotized; lobes well-developed; slightly fimbriate; phallobasic rod linear; phallobasic struts fused to phallobasic apodeme; phallic apex large, triangular; phallic plates broad ( Fig. 35 View Figs ).

Variation. Length 7.5–8.5 mm; width 2.0– 2.8 mm. The elytral disc is more yellow in some of the paratypes.

Natural History. The available specimens were collected in November, December, and January. Nine specimens were reared from tree boles.

Distribution. This species is known from Santa Catarina and São Paulo in southern Brazil.

Etymology. The specific epithet galbina is a Latin adjective that stems from galbus (= yellow). I refer to the color of the epipleural margin.
