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
).
