Ant.4 rather short and wide, 2 usual sensilla not especially thickened but distinct, a subapical organite and a basal microsensillum present. Ant.3 organ consisting of 4 low papillae, 2 sensory rods, 2 smooth sensory clubs without clear ribs, 5 guard setae, and a lateral microsensillum (Fig. 52). Ant.1 and 2 usually with 8 and 13 setae, respectively. PAO wide (length/width ratio ca 1.5), with (7)8-10 composed vesicles set close together. Labrum with 7 setae and 2 prelabral ones. Apical part of labium with thick terminal setae on papillae A, B and C (ABC - type), seta A clearly thicker, 6 long (e2 absent) and four spiniform (a1, b1-2 and d2), guard setae, a1shorter than others. Proximal field of labium with 5 setae, basal fields (mentum and submentum) with 4 and 5 setae. Maxillary palp simple, with 2 sublobal setae.</paragraph>

Upper subcoxae with two pso and (2)3-(3)4-(3)4 setae, respectively. Generally granulation rather fine, but areas of clearly enlarged granules usually present around some pso and in mid and lateral parts of thorax. Dorsal chaetotaxy almost symmetrical, setae smooth and rather thick, clearly differentiated into macro and microsetae, sensilla poorly distinguishable, 1/011/222121 (dorsal) and 2/000/00010 (ventral), only lateral ones on Th.2-Abd.1 and posterior one on Abd.5 always distinct (Figs 50, 54). Sensillum on coxae of Lg.3 present. Th.1 with (4)5+5 setae. Terga of Th.2-Abd.3 with 3, Abd.4 with 2 and Abd. 5 with 1, pairs of axial microsetae, additionally each tergum with 1+1 posterior axial mesosetae set slightly out of line with microsetae. Unpaired dorsal setae: d0 on head, microseta m0 on Abd.4, microseta a0 on Abd.5, and only one macrosetae (m0) on Abd.6, supplemented by 2+2 prespinal microsetae (Figs 50, 54).
