Material.

Type locality: Brazil, São Paulo, Juquitiba, Sítio Sonho do Vovô, Atlantic forest.

Type specimens. Holotype, female, pinned. Original label: “Sítio Sonho do Vovô, Juquitiba - SP - 22-IV-1988 - (V) L.A. Joaquim, col." DCBU / UFScar, São Carlos.

Paratypes (DCBU): 1 female, same as holotype; 2 males, Brazil, Barueri, SP, 11.V.1966 and 22.I.1966; 1 male: Brazil, Estação Florestal, Caraguatatuba, SP, 40 m, VII.1965.

Diagnosis.

This species is similar to Aleiodes melanopterus . It can be distinguished by colour pattern: mesonotum black, contrasting with orange mesopleuron, metapleuron, and propodeum; smaller oral opening and clypeus not strongly protruding; striated sculpture on dorsal part of hind coxa; fore wing vein R1 relatively shorter.

Description.

Female. Body length 9-9.2 mm, fore wing length 8.2 mm.

Head (Fig. 4). Flagellum with 60 flagellomeres, F1 2.5-3 times longer than wide, F2 about twice longer than wide, remaining flagellomeres almost twice as long as wide; malar space ½ basal width of mandible; MS/EH 0.2; TW/EW 0.62; occipital carina absent ventrally, not meeting hypostomal carina (Fig. 6); oral opening width slightly greater than clypeo–antennal distance; clypeus height/width 1/3; clypeus not protrud ing, without carinate boarder; OS/MS 3.1-3.2; OOD/OD 0.87; face rugo-striate; frons and vertex smooth; temples smooth scattered with punctuations near occipital carina; maxillary palpus swollen, especially segments 2 and 3.

Mesosoma(Fig. 8). Pronotum smooth laterally and middorsally, granular-rugulose anteriorly; propleuron smooth; mesonotum weakly coriaceous; mesoscutum with short median posterior carina; notauli weakly scrobiculate; mesopleuron smooth and shinny, precoxal sulcus absent; epicnemial carina complete; propodeum smooth to weakly coriaceous dorsally, carinate-rugose basally, median carina complete. Legs:tarsal claws pectinate; hind coxa dorsally striate, same sculpture occasionally present on mid and fore coxa (Fig. 9). Wings (Fig. 15): dusky; R1/R2 0.29-0.33; R1/recurrent vein 0.38-0.4; 1CUa/1cu-a 1.7-2.5; basella/mediella 0.41-0.47.

Metasoma(Fig. 13): T1 length/width 1.19-1.25; T2 length/width 0.73-0.75; T3 length/width 0.48-051; T1 and T2 weakly rugose, apically smooth, raised triangular smooth area present; reminder metasomal terga smooth; OL/HBTL 0.21; HTS/HBTL 0.27-0.36.

Colour (Fig. 1): Black; mesopleuron, metapleuron and propodeum bright orange.

Male. Essentially as the female, but with slightly larger eyes; body length 10 mm; flagellum 59-63F.

Etymology.

The species is named in honour to Scott Shaw, for his contribution to the knowledge on this group.

Distribution.

Brazil, State of São Paulo, Brazilian Atlantic Forest.

Comments.

Despite the superficial resemblance with melanopterus, this species have quite distinctive characters, including the lack of a strongly protruding clypeus, which has been considered one of the synapomorphies for the Neotropical melanopterus species-group clade ( Shaw 1993; Fortier and Shaw 1999).
