Sinanarchusini Pace, 2013: 22 (original description; type genus: Sinanarchusa Pace, 2013 View in CoL ); Maruyama et al., 2014: 394 (synonymized with Himalusini View in CoL ).

Diagnosis. Himalusini is distinguished from other aleocharine tribes by the combination of the following character states: paramere distinctive, apical lobe partially or entirely covered with fine scale-like protuberances; lacinia with several large elongate or triangular teeth near apex; labium with extremely broad ligula; labial palpus with two palpomeres; prementum transverse with elongate, delicate and thin lateral lobes of apodeme (component “r” of premental sclerite in Weide et al. (2014)) that converge at their apices; maxillary palpus with a pseudosegment; tarsal formula 4-4-4 or 4-4-5 (modified after Maruyama et al. 2014; most of these features shown in their figures 2–5).

Remarks. Parabrachida decipiens Cameron, 1939 (= Himalusa thailandensis Pace, Klimaszewski & Center, 2010 , syn. nov.) is known to feed on the leaves of sewer vine ( Klimaszewski et al. 2010), and is the only known leaf-feeding species of Aleocharinae, but the feeding habit of other species of this tribe remains unknown.
