Antennifer subquadrangular. Antenna ( Figs. 23–24 ) with 4 antennomeres: I shorter than II and glabrous, II long, with 1 lateral, 1 dorsal, and 3 ventral setae, II with 2 ventral setae and a small ventral projection, IV with a large dorsal spot and 2 ventral spots. Clypeus trapezoidal ( Fig. 21 ), each side with 1 anteroclypeal seta and 2 lateroclypeal setae. Labrum ( Fig. 21 ) as long as clypeus, each side with 3–4 posterolabral setae, 3 laterolabral setae, 1 mediolabral seta, and 2 anterolabral setae. Epipharynx as in Figs. 3, 4 , and 22. Corypha: epizygum distinct; clithra absent. Haptomerum: zygum as a cross-bar with 7 sensillae; 3 heli present; 1 denticlelike seta on right side of zygum. Paria: right and left acroparia with 8 setae; right acantoparia with 18 setae and left with 22 setae; acroparia-acanthoparia separation inconspicuous; gymnoparia narrow; chaetoparia well-developed, with 102 setae on right side and 110 setae on left side, anteromedial setae more robust than posterolateral setae; plegmatia present; proplegmatia absent; laeotorma shorter than dexiotorma, epitorma narrow and depressed, pterotorma small and fused to laeotorma. Pedium longer than wide. Haptolachus: crespis semicircular; nesium internum prominent; nesium externum acuminate and sharp; phoba absent; right lateral margin with 3 setae, left lateral margin with 7 setae. Right mandible ( Figs. 25–26 ): incisor with shallow groove distal to proximal tooth (S3). Dorsal face with 1 short and 1 long seta near S3 base; external face with 9 setae. Molar with 2 dorsal setae; brustia with 9–10 setae; ventral face with stridulatory area with 56 subparallel striae; ventral process welldefined. Left mandible ( Figs. 27–28 ): incisor similar to that of right mandible. External face with 5 setae; dorsal face with 1 short and 1 long seta near S3 base. Molar with 6 dorsal setae; acia long with apical setae; ventral stridulatory area with 56 subparallel striae; brustia with 12 setae; ventral process well-developed. Maxillae ( Figs. 29–30 ): galea and lacinia separated by a suture; galea with sharp uncus; lacinia with 2 unci. Stipe with stridulatory area with a row of 5–6 sharp denticles and a truncated anterior process. Palp with 4 palpomeres: I with 1 seta, II with 3 setae, III with 1 seta, and IV with small sensilla at apex. Hypopharynx ( Fig. 31 ): Posterior right margin with 8 long, thin setae and left with 6 setae; hypopharyngeal sclerite asymmetric with a prominent right process. Labium: Ligula ( Fig. 31 ) with 21 short, thick setae and 7 short, thin setae; palp with 2 palpomeres: I narrower and shorter than II; II with small apical sensilla. Thorax: Pronotum formed by 4 lobes. Thoracic spiracle 0.47 mm long and 0.33 mm wide, respiratory holes with irregular margin, 18 holes fit across longitudinal radius. Meso- and metanota with 3 lobes. Anterior and medial legs slightly smaller than posterior legs. Tarsungulus with 1 distal seta and 1 medial seta. Abdomen: Spiracles I–II 0.27 mm long and 0.27 mm wide; III–VI 0.33 mm long and 0.27 mm wide; VII–VIII 0.37 mm long and 0.33 mm wide. Urotergites VII–IX with most setae placed on 1–2 transverse rows; X with semicircular furrow. Barbula with 9–12 setae, slightly thicker than setae of the tergite. Raster ( Fig. 32 ): each palidium with 9–11 small, wide pali; each tegilla with 28–34 setae, of which 8–10 preseptular; tegilla setae long with apex curved and spatulated. Lower anal lobe formed by 33–46 setae, anterior setae similar to the tegila setae and posterior setae thin, straight, and sharp. Figs. 18–19.

Gomes (collector), 29.X.2010 , 7 larvae ( MZSP , file: 10296), 14.IX.2010 , 3 larvae ( UEMS ) . Remarks. Similar to other Anomala species , the larva of A. testaceipennis has each side of the head with one anterofrontal seta, one anteroclypeal seta, and one mediolabral seta. In addition to the identification key, the comparison of chaetotaxy can help in the larval identification ( Table 1 ).
