Diagnosis

Males of A. callitra sp. nov. can be distinguished from all species for which males are known except A. corundaria sp. nov. by a small body size (carapace length <4.0 mm), and the presence of a copulatory organ with a short embolus (embolus length / bulb length <1.5) and an angular bulb with a slight ridge adjacent to the embolus ( Fig. 94J–Q View Fig ). Males of A. callitra can be distinguished from those of A. corundaria by the presence of a thicker, straighter embolus ( Fig. 94L–M View Fig ; cf. Fig. 95 View Fig ).

Females of A. callitra sp. nov. are unknown.

Etymology

The specific epithet ‘ callitra ’ is an ad-hoc formation, referencing the cypress pine habitat in which both specimens of this species were collected. It is to be treated as a noun.

Distribution and natural history
