description: ZALANODIUS CONVEXUS (MELLO- LEITÃO, 1940)   COMB. NOV.  
 Berlesecaptus convexus Mello-Leitão, 1940: 101; Kury 2003a: 23 (removed from Phalangodidae to Grassatores incertae sedis).   
 Diagnosis: Closest to Z. latifemur, in the compact shape and short legs (as opposed to slender body with longer legs in Z. bicornutus and Z. hirsutus) but with tegument much more finely granular and not wrinkled. Leg IV densely covered by small, long-haired setiferous tubercles (instead of covered by very large ones in Z. latifemur). Metatarsus IV normal (instead of incrassate with a powerful spur in Z. bicornutus).   
 Description, male neotype: Dorsum ( Figs 21A, B, 22A– D). Dorsal scutum outline classic alpha, carapace elongate, scutal groove posterior margin in obtuse angle. Mesotergum divided into four areas, area I entire, larger than the others, expanded to the sides. All areas unarmed, covered by irregular, large setiferous tuber- cles. Posterior border of scutum and free tergites each with a single transverse row of setiferous tubercles. Ocularium high, inclined frontwards, topped by a short protuberance, placed far from the anterior margin of carapace. Frontal hump low, unarmed. Venter (Figs 21C, 23A–C). Coxa IV with ventro-apical, rod-like ventral apophysis connected to sternite II. Sternite II with small, anterior projections partly covering the stigmata. Chelicera (Fig. 22B). Weakly developed, basichelicerite short. Pedipalpus (Fig. 23F). Articles short, trochanter with ventral setiferous tubercle, femur with one ventrobasal setiferous tubercle, tibia and tarsus armed with very weak ventro-ectal and ventromesal spines. Legs (Fig. 23D, E). Legs I−III short, unarmed. Leg IV considerably stouter than the others, trochanter unarmed, femur and tibia IV incrassate, femur to tibia densely covered with coarse, long-haired setiferous tubercles. The distitarsus I has three articles (as can be clearly seen on Fig. 23E), but the suture between the two distal-most is very shallow, and led to the count of only two by Mello-Leitão (1940; the nearest species, Z. latifemur has clearly only two articles, without any suture, and other species have three articles, so it appears that Z. convexus shows an intermediate state: trimerous in the process of becoming bimerous). Tarsal counts 4(3) or 3(2) (depending on the interpretation)/6(3)/5/5. Genitalia (Fig. 24A–C). Distal setigerous part of truncus divided into a basal malleus and a distal LP. LP slender, gently curved ventrally. Prepodium extremely elongate, forming angle with truncus. Malleus ventrally with longitudinal wide ditch. Macrosetae A1−A2 inserted laterally on malleus. Macroseta B ventral on malleus. Macrosetae C1−C3 short, D very small on the laterals of LP. Macrosetae E1−E2, short, forming rectangle on ventral surface of LP. Skirt flabellar, expanded laterally, with deeply serrate margins. Stylus C-shaped. Coloration. Body and appendages uniform 53 Moderate Orange.
