Etymology: dawnarnallae: Named for Dawn Arnall, who both funded the expedition
that led to the discovery of this species. She also provided critical support and advice to the Bird’s Head Seascape marine conservation initiative that now protects the habitat of this new species.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 10 - 20 m (Ref. 123061). Tropical
Western Central Pacific: Indonesia (West Papua Province).

Maturity: Lm ?  range ? - ? cm
Max length : 3.9 cm SL male/unsexed; (Ref. 123061)
The species is currently known only from the type locality, where the habitat consists of a gently sloping bottom with clean white sand and was well-removed (more than 100 m) from reef habitat, in an area exposed to periodic strong currents. An estimated 20 individuals were observed in an area approximately 30 sq.m and were seen mainly in pairs, occasionally solitary, although invariably associated with an unidentified snapping shrimp of the genus Alpheus that share the burrows (a symbiotic relationship found in all Vanderhorstia species (Ref. 123061).
