Heteropogon martini
Wilcox, 1965
Heteropogon martini is a of robber fly ( Asilidae) described by Wilcox in 1965. As a member of the Heteropogon, it belongs to a group of small to medium-sized predatory flies known for their distinctive courtship and twig-perching habits. The species is part of the diverse asilid fauna of North America, though specific details about its remain poorly documented compared to some .
Identification
Heteropogon martini can be distinguished from other Heteropogon primarily by male genitalia characteristics and geographic distribution. Within the , species identification typically requires examination of male terminalia. H. martini was described from Arizona, which may help separate it from eastern such as H. macerinus. The specific epithet 'martini' honors an individual (likely an entomologist), but this does not aid field identification. No published diagnostic key specifically including H. martini was found in available sources.
Appearance
Specific morphological details for H. martini are not documented in available sources. Members of the Heteropogon are generally small to medium-sized robber flies, typically 10–15 mm in length, with relatively drab coloration. Males possess ornamental setae (modified hairs) on the front , which are used during courtship. The body is characteristically compact with a tapered typical of the Brachyrhopalinae.
Distribution
The was described from Arizona, USA. No additional distribution records were found in available sources.
Ecological Role
As a member of the Asilidae, H. martini functions as an aerial of other insects. Robber flies in this typically employ a sit-and-wait hunting strategy, perching on elevated twigs to survey for flying prey.

Taxonomic Note
Heteropogon martini was described by Wilcox in 1965. The Heteropogon is part of the Brachyrhopalinae within Asilidae. The specific epithet likely honors someone with the surname Martini, though the etymology was not explicitly stated in the original description.
Data Deficiency
This is notably data-deficient compared to such as H. macerinus, which has been documented in detail for and . No published studies specifically addressing H. martini , behavior, or ecology were located.
