Diagnosis.
This species can be distinguished from the closely related L. carolinae only by the genitalia. Aedeagi are similar, but those of L. camplyacra have bent ventral processes. The terminalia of female L. camplyacra have partially sclerotized subgenital plates and are longer and narrower than those of L. carolinae , with relatively shorter coxites. No intermediate forms are known.
Both L. camplyacra and L. carolinae share a similar gestalt with L. brevipenne . The latter is endemic to the Interior Highlands of the south-central United States. Lathrobium brevipenne can be distinguished from either species by genitalia. Its aedeagus is highly variable in shape but is never fully sclerotized (Figs 24-26 View Figures 24–26 ). The females of L. brevipenne have larger, more sclerotized subgenital plates.
Description.
External morphology (Fig. 5A View Figure 5 ) identical to L. carolinae . It differs only in the sexual characters.
♂: Aedeagus (Fig. 5E, F View Figure 5 ) with median lobe well sclerotized; ventral process strongly curved, distal tip lying beyond median foreman in lateral view; dorsal plate long; internal sac with three patches of rugose flagella, visible as one structure when invaginated.
♀: Apical lobes of paraproct shorter than continuous basal portion in dorsal view; proctiger conical; sternum IX with coxites and valvifers fully divided, coxites less than ½ length of valvifers (Fig. 5B View Figure 5 ); subgenital plate a lightly sclerotized chevron.
Etymology.
The specific name is from the Greek camplyo - meaning bent, and acra meaning tip, in reference to the bent ventral process of the aedeagus.
Distribution and ecology.
Lathrobium camplyacra inhabits mid-elevation (600-1600 m) hardwood forests in the Great Balsam, Plott Balsam, and Cowee Mountains of the southern Appalachians (Fig. 27 View Figure 27 ). This area is bordered by the Cullasaja River and Little Tennessee River to the west, the Maggie Valley to the north, and the French Broad River Valley to the east. A single specimen from the CNC collection was reportedly collected from Newfound Gap in the Great Smoky Mountains, which is well outside of this range and needs to be verified.
