Heteromphrale Kröber 1937: 221. – Hardy 1966: 1; Kelsey 1969: 286; 1971: 284; 1973: 332; Woodley 2009: 651. Type species (by original designation): Pseudatrichia chilensis Kröber 1928: 31.

Diagnosis

Body length: 2.5–4.0 mm [male], 2.7–5.0 mm [female]. Cream-white with yellowish-brown suffusion; eyes contiguous in male, frons broader than ocellar tubercle in female; antennal flagellum approximately twice length of scape and pedicel combined, attenuate and pyriform, notched apically; scutum light brown to dark grey, with cream-white to yellow patches marginally (pale area often more extensive in female); entire thorax overlain with glaucous pubescence; wing vein M1 meeting vein R5, forming closed petiolate cell r5; R4 branching from R5 along basal half of cell r5; abdomen with tergites either dark brown-grey with pale white to yellow band posteriorly, or vivid white with orange-brown suffusion laterally (and medially in female); tergite 2 sensory setae well defined (Fig. 1); male epandrium split medially as two sclerites, halves sub-quadrangular with posterior margins flared or tapered laterally, or large and globose; epandrium not completely covering gonocoxite ventrally; gonocoxite and aedeagus extended anteriorly from anterior margin of epandrium a relatively short distance; gonocoxite irregular, largely reduced, with strongly sclerotized dorsal process; gonocoxal apodeme relatively thickened; hypandrium as paired lobes, size and shape variable, with margin of setae, but no large setal brushes; lateral aedeagal bulb present; distiphallus bifid, recurved dorsally at base or straight, slender or slightly thickened, arms parallel or divergent. Female sternite 8 longer than tergite 8, almost level with cerci, broadly rounded or weakly emarginate (not forming distinct lobes posterolaterally); 6–7 acanthophorite spines present on lobes of well defined tergite 9+10; furca ring-like, dark-sclerotized; spermathecae paired, sclerotized and irregular-shaped; spermathecal sac simple, minute, elongate.

Comments

Heteromphrale is closely related to Brevitrichia, a genus found primarily in western North America and throughout Central America (Kelsey 1969; Woodley 2009). Heteromphrale can be differentiated from Brevitrichia by the shape of sternite 8 in the female (apically emarginate with rounded posterolateral lobes in Brevitrichia), male distiphallus short and thick (relatively long and thread-like in Brevitrichia) and the distiphallus straight (highly reflexed basally in Brevitrichia). The distiphallus of Brevitrichia can be greatly elongated, with the basiphallus reflexed upon itself up to 180° as found in the proratine genus Cyrtosathe Winterton & Metz, 2005 (Winterton and Metz 2005). This complex arrangement of the distiphallus in Brevitrichia often projects anteriorly into the abdominal cavity and is supported by aedeagal guides formed by paired, blade-like extensions of the hypoproct; the aedeagus is largely contained within the genitalic capsule in Heteromphrale, with hypoproct extensions absent. The distinct dorsal processes (physically ventral) on the gonocoxites of Heteromphrale (Figs 2–3) are similar to those found in some species of Propebrevitrichia Kelsey, 1969 (see Winterton 2005) and indicate a likely close relationship between these genera.

Distribution

1
Scutum with glabrous, glossy dorsocentral area (circular in male, linear in female) (Fig. 5C, D); basal antennal flagellomere abruptly pear-shaped; mouthparts tiny, much smaller than oral cavity; female frons with extensive pile (Fig. 4C); abdomen distinctly matte white with brown suffusion laterally and ventrally (Fig. 7A, B), transverse brown line anterior to dark brown spot encompassing tergite 2 sensory patch 
  Heteromphrale chilensis (Krober)
–
Scutum with uniform covering of pubescence, lacking a glabrous or glossy mark (Fig. 5A, B, E, F); basal antennal flagellomere more conical-shaped, tapering evenly; mouthparts usually normal-sized, nearly filling oral cavity; female frons with less extensive pile; abdomen in both sexes more extensively dark brown, with white only on posterior margins of tergites (Figs 6A–B, 8A–B)   ► 2
2
Wing with vein R4 diverging from vein R5 at point in basal quarter of cell r5 (Fig. 8B); tergite 2 sensory patch as relatively small single patch, slightly narrowed; male epandrium enlarged, bulbous, without distal fringe of long, white setae on posterior edge (Figs 3A–B, 8A, 10C); female sternite 8 shallowly emarginate posteriorly and without a fringe of long setae; acanthophorite spines stout (Fig. 9G–H) 
  Heteromphrale cyanops (Edwards)
–
Wing with vein R4 diverging from vein R5 at point between one-quarter and one-half of cell r5 (Figs 6A, B); tergite 2 sensory patch large and distinct, divided into two small patches with setae directed medially; male epandrium not bulbous, size subequal to preceding abdominal segment, with distal fringe of long white setae on posterior edge (Fig. 2A, B, 10A); female sternite 8 distally rounded with dense long thin setae apicolaterally and distally; acanthophorite spines thin and wispy (Fig. 9A–C)
