Haromyia Runyon, gen. nov.
No full textGenus Haromyia Runyon, gen. nov. Type species. Haromyia iviei, sp. nov. Male and female habitus (Figs 1, 2). Diagnosis. Haromyia can be distinguished from other Dolichopodidae by the combination of small body size (1.0– 1.5 mm), bulging clypeus with six large setae (Figs 1, 3), and wing veins that evenly diverge from base to tip (Fig. 4). Haromyia keys to Achalcus Loew and Australachalcus Pollet or Enlinia and Harmstonia in Nearctic and Neotropical keys (Robinson 1964; Robinson & Vockeroth 1981; Bickel 2009). On Dominica, Haromyia could be confused with Enlinia or Harmstonia to which it keys in Robinson (1975). The presence of six large setae on a bulging clypeus separates Haromyia from all of these. The only other New World dolichopodids I know of with clypeal setae are female Harmstonia, which lack acrostichal setae and have a dorsal arista; the coastal species Nanomyina barbata (Aldrich), which has a dorsal arista, yellow setae, and wing veins R 2 + 3, R 4 + 5 and M 1 nearly parallel; some Discopygiella Robinson which have fore tibia with a row of setae on distal half, R 4 + 5 and M 1 nearly parallel, and hypopygium enlarged, disc-like and laterally flattened; and some Nearctic Gymnopternus Loew which have setae on the dorsal surface of antennal scape. Etymology. Haromyia is named to honor the botanist and entomologist, Harold E. Robinson, in recognition of his many contributions to the study of Dolichopodidae, especially describing the Dominica fauna and for his unequaled work on the micro-dolichopodids.Published as part of Runyon, Justin B., 2015, Haromyia, a new genus of long-legged flies from Dominica (Diptera: Dolichopodidae), pp. 589-595 in Zootaxa 3964 (5) on page 590, DOI: 10.11646/zootaxa.3964.5.10, http://zenodo.org/record/23817

The epithet is derived from the Latin salinus meaning “of salt” and is in reference to the salty and alkali habitats where this species occurs (Figs 15–20). Type material. HOLOTYPE ♂, labelled: “ MONTANA: Golden Valley Co. | alkali area/ Deadman’s Basin | N46°20.528′; W109°22.937′ | 04July2017, J.B. Runyon ” [USNM, type number USNMENT01519228].

Specimens of Hurleyella salina sp. nov. have been collected at five localities, three in Montana and one each in Idaho and Wyoming (Fig. 21), all with at least some crusted salt and/or other minerals on the soil surface. The type locality, Deadman’s Basin in central Montana, has large areas of salt (Fig. 15) and H. salina sp. nov. was found there sweeping nearly bare soil with scattered grasses; most specimens were taken from areas with mud cracks and at least some signs of a little moisture (Fig. 16). Specimens were collected at the Piedmont Pond site in southwestern Montana from similar habitat but with more grasses and less salt on the soil surface (Fig. 17). The Gyp Springs site in southcentral Montana is part of the Chugwater Formation of red sandstone, and specimens were found on bare soil at the bottom sides of a small canyon where moisture evaporated and left a line of crusted salt (Fig. 18). In west central Wyoming, H. salina sp. nov. was found sweeping bare, moist areas of side pools along Salt Creek with large amounts of crusted salt on the soil surface (Fig. 19). Lastly, in southeastern Idaho, adults were found on the dry, crumbling surface of a sloping travertine mound composed of low-magnesian calcite and formed by a cold spring (Chafetz & Folk 1984; Fig. 20). Hurleyella salina sp. nov. is distinct, in a number of respects, from the other three species of Hurleyella. For example, the head of H. salina sp. nov. is relatively short and broad (Fig. 6). Several characteristics of the hypopygium (Figs 9, 10) of H. salina sp. nov. are unlike the other species, including lacking an obvious flange at apex of the surstylus, lacking a strongly sclerotized apical epandrial margin, having a nearly symmetrical hypandrium, and the epandrium almost wholly divided ventrally into left and right lobes.Published as part of Runyon, Justin B., 2019, Two new species of Hurleyella Runyon & Robinson (Diptera: Dolichopodidae), with the first record from the Neotropics, pp. 548-560 in Zootaxa 4568 (3) on pages 552-558, DOI: 10.11646/zootaxa.4568.3.8, http://zenodo.org/record/260177

The following combinations of characters should separate females of E. aetheoptera: femur III with preapical anterior seta equal to or longer than width of femur at insertion; wing broad (length approximately equal to 2 times width), bend in section of M 1 beyond crossvein dm-cu occurring at or just basal to termination of CuA 1 at wing margin. Etymology: derived from Greek aethes (ảΦς) = unusual, strange + ptera (πτέρον) = wing, in reference to the curiously modified wings of the male. Holotype: 3: ARIZONA: Cochise Co., Ramsey Canyon, Huachuca Mtns., 5500 feet, 23 -IV- 2002, R. Hurley & J. Runyon. Deposited: CAS. Additional (non-type) material: Ƥ: same data as holotype. Remarks: The male and female of E. aetheoptera were collected with E. ramseyensis along Ramsey Creek, Arizona, from a cavity created by several large boulders with some standing water underneath.Published as part of Hurley, Richard L. & Runyon, Justin B., 2009, A review of Erebomyia (Diptera: Dolichopodidae), with descriptions of three new species, pp. 38-48 in Zootaxa 2054 on pages 41-42, DOI: 10.5281/zenodo.27477
Chrysotus keyensis Runyon & Capellari 2018, sp. nov.
No full textChrysotus keyensis Runyon & Capellari, sp. nov. (Figs 4a, b, 5) Description. Male. Body length, 1.3–1.4 mm. Wing length, 1.1–1.2 mm, width, 0.4–0.5 mm. Head: Frons dark brown to black, with violet reflections; antenna wholly yellow; face yellow; proboscis yellow with yellow setae; palpus (Figs 4a, b) long, yellow, broadest basally, tapered and ending in nearly round, mostly black lamella; basal half with several long, yellow setae (ratio tibia I:palpus, 20:22) (MSSC). Thorax: Mesonotum and scutellum metallic green with violet reflections; mesopleuron brown with some bluish reflections and little pruinosity. Wing: Halter yellow, calypter brownish at apex. Legs. I: 24, 20, 11, 4, 3, 2, 2. II: 24, 24, 12, 6, 4, 2, 2. III: 28, 30, 7, 7, 4, 2, 2. Legs yellow except coxa II, base of coxa III, and apical tarsomeres which are brown. Setae on coxae yellow. Femur III with rather long, yellow ventral setae (longest about half width of femur) along full length (Key West specimen) or with long ventral setae only at base (Big Pine Key specimen). Hypopygium brown, not dissected; cercus yellow, short, with some brown hairs. Female. Body length, 1.4–1.5 mm. Wing length, 1.4–1.5 mm, width, 0.5–0.6 mm. Similar to male, except without MSSC and as noted. Head. Palpus a little enlarged, as long and as broad as face, dark brown, covered by brown setae that appear yellow in certain lights, with longest setae along apical margin. Antennal postpedicel brown. Legs. I: 22, 22, 12, 5, 3, 2, 2. II: 26, 29, 14, 6, 4, 3, 2. III: 30, 32, 8, 8, 4, 3, 2. Etymology. Named for the Florida Keys, the coral archipelago where specimens were collected (Big Pine Key and Key West). Material examined. HOLOTYPE ♂, “FLA: Monroe Co., Big | Pine Key (north end) | V-14-20-1990 | E. G. Riley, Malaise | trap, Pinelands”, “HOLOTYPE | ♂ Chrysotus | keyensis | Runyon & Capellari 2018 [red label]”. (USNM, type number USNMENT01447152). Paratypes: same data as holotype (1 ♀, USNM); Florida, Monroe Co., Key West, 22 November 2002, R. Hurley & J. Runyon (1 ♂, 3 ♀, MTEC). Distribution. USA: Florida. Remarks. There are small differences in the shape of the palpi and size of ventral setae on femur III between the male from Big Pine Key and the male from Key West. More specimens are needed to assess morphological variation and determine if these specimens might represent two species. Specimens from Key West were collected south of the airport between salt ponds and the road (Road A1A) by sweeping moist, sandy soil of shaded trails.Published as part of Runyon, Justin B. & Capellari, Renato S., 2018, Palpi aplenty: new species in the Chrysotus longipalpus species group (Diptera: Dolichopodidae), pp. 579-585 in Zootaxa 4399 (4) on page 581, DOI: 10.11646/zootaxa.4399.4.8, http://zenodo.org/record/120690
