No one ever called it a "Digital Ethernet Personal Computer Bus

meaning behind the DEPCA name.

Yes, that's what it meant. "DELNI" - Digital Ethernet Local Network Interface. "DESTA" - Digital Ethernet Station Termination Adapter. DELQA - Digital  Ethernet Local Q-Bus Adapter (this one probably means something else. Working?). DEMPR - Multi Port Repeater. DEREP - Repeater.  And so forth. Yeah, nobody spelled it out, but those DExxx names usually meant what the device was. DEBNT, DEUNA, DEQNA. Same naming convention. I'm probably missing several.

The DEPCA manual (http://www.bitsavers.org/pdf/dec/ethernet/depca/EK-DEPCA-PR-001_Apr89.pdf) says "DIGITAL Ethernet Personal Computer Adapter", without "Bus".

DELQA was "DIGITAL Ethernet Local-Area-Network to Q-bus Adapter" according to its user guide.

It's predecessor, the DEQNA, was "Digital ETHERNET Q-Bus Network Adapter", according to its user guide, or "broken", according to most people :-)
