Aphonodiacanthus maculatus Tonon & Campos sp. nov. Figs. 5–7; Table 2 Etymology. The specific epithet is derived from the Latin maculātus or macula, meaning “spot”, referring to the spots present on the pronotum, tergites, and legs of the species. Type locality. Itamaraju, Bahia, Brazil. Type Material. Holotype: BRAZIL • ♂; BR, BA, Itamaraju / Par[que]Na[cional do] Monte Pascoal / 08– 11.III.2012 / DIAS, P.G.B.S. et al. col. (MZSP). Diagnosis. This species is separated from the other Aphonodiacanthus species by: body covered with spots throughout pronotum, abdominal tergites, and legs.Thoracic sternites medium brown.Male genitalia:pseudepiphallic sclerite medial region of anterior margin sub-straight in dorsal view. Pseudepiphallic paramere not reaching half of lateral lobe of pseudepiphallus in dorsal view. Ectophallic invagination: ventral projection of ectophallic invagination longer than half arc. Endophallic sclerite: endophallic apodeme thin, short, seven times shorter than End. Description. Head: Median ocellus absent. Occiput and vertex pubescent. Fastigium wider than long, pubescent (Fig. 5D). Frons, labrum, clypeus smooth. Antennal scapes longer than wide, pubescent. Maxillary palps: articles 4 and 5 almost equally sized, article 3 longer, article 5 clavate. Thorax: Pronotum longer than wide, pubescent. Posterior margin of pronotum covering metanotum (Figs. 5A, B). Dorsal disc of pronotum cephalic margin almost straight, caudal margin almost straight (Fig. 5A). Lateral lobe of pronotum ventro-cephalic angle rounded, ventro-caudal angle gradually ascending (Fig. 5B). Forewings very short, not surpassing the metanotum (Fig. 5E, red arrow). Legs: TI with three apical spurs, two inner and one outer. TII with four apical spurs, two inner and two outer. TIII subapical spurs formula: 4/5, three spines between each spur, 11 a 14 spines above most proximal subapical spur on inner and outer sides. TIII apical spurs formula: 3/3; TIII inner apical spurs: iad>iam>iav; outer apical spurs: oam>oav>oad, oav and oad almost equally sized. Basitarsus spines with four spines on outer side and one on inner side, two apical spurs equally sized. Abdomen: Tergites pubescent (Figs. 5A, B). Cerci pubescent. Supra anal plate posterior margin rounded, lateral margins V-shaped (Figs. 5F, H, red arrows). Subgenital plate posterior margin rounded, slightly elongated (Fig. 5G). Male genitalia (Figs. 6A–D; Figs. 7A–C). Pseudepiphallus: pseudepiphallic sclerite anterior margin upcurved, Cshaped in lateral view (Fig. 6C, 7C, red arrow), medial region of anterior margin almost straight in dorsal view (Figs. 6A, 7A). Lateral lobe of pseudepiphallus same as genus description. Pseudepiphallic paramere not reaching half of lateral lobe of pseudepiphallus in dorsal view (Figs. 6A, 7A), posterior portion divided into two lobes, not exceeding the medial region of lateral lobe of pseudepiphallus in dorsal and ventral views (Figs. 6A, B; 7A, B); apex of lobes equally sized, equally and strongly sclerotized, inclined inwards in ventral view (Fig. 6B; Fig.7B). Rami same as genus description (Figs. 6A, B; 7A, B). Ectophallic invagination: Ectophallic apodeme and lateral lobe of pseudepiphallus almost equally sized, inclined outwards in dorsal and ventral views (Figs.6A, B; 7A,B); arc open; ventral projection of ectophallic invagination longer than half arc (Figs. 6B, 7B). Ectophallic fold: membranous, finger-shaped, surpassing pseudepiphallic paramere apex. Endophallic sclerite: longer than wide, shorter than half of apodemes, dorsoventrally flattened, endophallic apodeme present, thin, short, seven times shorter than endophallic sclerite (Figs. 6B, 7B). Female. Unknown. Coloration. Occiput, vertex, fastigium, frons and genae yellowish-brown, bristles yellowish-brown. Labrum and clypeus whitish.Antennal scapes and antennomeres light yellow, bristles yellowish-brown (Fig. 5D). Maxillary palps segments light yellow, the apex of 5 th segment whitish. Pronotum yellowish-brown, bristles darker, irregular spots throughout structure dark brown (Fig. 5A). Thoracic sternites gray; abdominal sternites pale yellow to medium brown, not uniform (Fig. 5C). Abdominal tergites yellowish-brown, posterior margin darkened, brown spots throughout structure; sternites medium brown (Fig. 5A, B). Male supra anal plate dark brown, lateral margin and medial region lighter (Fig. 5F). Male subgenital plate medium brown (Fig. 5G). Cerci yellowish-brown. Legs I and II yellowish-brown with brown spots. FIII yellowish-brown with brown spots. TIII yellowish-brown with brown spots, spines yellowish-brown with apex brown, spurs yellowish-brown with basal portion brown. Basitarsus light yellow. Remarks. The apex of lateral lobe of pseudepiphallus is incomplete on Aphonodiacanthus maculatus Tonon & Campos sp. nov., apparently broken; sternites and subgenital plate have uneven coloring, which may be due to the conservation state of the specimen.
