Frons dark yellow (Fig. 8J). Orb 3 and Orb 2 parallel (Fig. 8J). Pedicel dark yellow; first flagellomere yellow (Fig. 8J). Clypeus dark yellow medially and brownish laterally. Palpus brownish yellow (Fig. 8J). Mesonotum mostly dark yellow (Fig. 8K). Postpronotal lobe yellow (Fig. 8L). Acrostichal setulae in ca. 14–16 irregular rows (Fig. 8K).
