( Figs. 2 A, 5–7) Diagnosis. Recognized by the following combination of characters: medium-sized body; fuscous dorsum ( Fig. 2 A); yellowish brown, broad head ( Fig. 5 ); grayish yellow, slender antenna; and identical color patterns of coxae ( Fig. 6 ) and femora ( Fig. 7 ). Most closely related to H. phuvasae , from which this new species can be distinguished by the pale antennal segments I and II, longer labium, dark metacoxa with whitish base, and different shape of ostiolar peritreme ( Table 1 ).
