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

Hurleyella brooksi Runyon & Robinson 2010, sp. nov.
No full textHurleyella brooksi Runyon & Robinson, sp. nov. Description: Very similar to H. cumberlandensis, showing only the following differences: Head: face with ventral half not as narrow (narrowest width approximately equal to width of first flagellomere), and more obviously widened toward palpus. Ochre pollen on frons and dorsal postcranium not as dense. Legs: coxae concolorous with pleura, but more yellowish in some specimens. Ratios of tibia: tarsomeres for leg I: 10–5–3–2–2–2; for leg II: 14–8–4–3–2–2; for leg III: 14–5–4–3–2–2. Abdomen: epandrial lobe with seta at apex only about one-third as long as seta near base (in H. cumberlandensis apical seta at least one-half length of basal seta). Surstylus (Fig. 5C) with 3 large blade-like setae directed medially (H. cumberlandensis has 2 large setae - the third seta is very small); the flange of surstylus is very broad and rounded apically (Fig. 5C). Female: Similar to male. Etymology: Named in appreciation of the dipterist Scott Brooks, who recognized and sent us the specimens of this species. Holotype: ♂, TEXAS: Brazos Co., College Station, Lick Creek Park, bottomland forest near creek, malaise trap, 28–30 March 2000, M. Buck (DEBU).

R 2+3 very short, fused with costa near midpoint of total wing length and slightly closer to termination of R 1 than R 4+5. R 4+5 nearly straight, very slightly arched toward M 1 apically. M 1 gradually arched far anteriorly on apical half of wing, lying alongside and nearly parallel to R 4+5 on apical third of wing. Length of distal section of vein CuA 1 about 3 times longer than crossvein dm-cu. CuA 1 slightly arched and fading apically, usually not reaching wing margin. Vein A 1 absent.

Similar to male except: face slightly wider; abdomen dorsoventrally flattened and usually arched ventrally, tergite 6 with short ventral setae along apical margin. Etymology. 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.

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
