Head relatively broad, slightly wider than thorax, and much wider than high in anterior view; male frons narrower than anterior ocellus at narrowest point, slightly produced anteriorly, female frons flat; occiput concave (male), or convex (female); male with single row of postocular macrosetae dorsally, female with multiple rows; parafacial setae present only as small patch of dark setae adjacent to gena (absent in female P. argentoides sp. n.); genal setae white; palpus narrow apically; antenna length equal to, or longer than head length; scape bulbous, thicker than pedicel and flagellum, with numerous stout, erect macrosetae; flagellum shape turbinate, abruptly tapered. Thorax with scutum covered with erect filiform setae, often of variable length, denser anteriorly and longer in male; central depression of prosternum usually with setal pile, sometimes absent; pleuron dark, overlain with silver-grey pubescence; metanepisternum with postspiracular setae absent; scutellum shape rounded in profile; fore- and hind femoral velutum patches absent; femora all subequal in length; hind femur with 1–6 (rarely more) anteroventral (av) setae, either subapically (1–2) or along entire length as series (3–6 or more); posterior surface of midcoxa with or without setae; scutal chaetotaxy (pairs of macrosetae) notopleural, 3–5; supra alar, 1; post alar, 1; dorsocentral, 4–5, scutellar, 2; wing hyaline to extensively infuscate, mottled and fenestrate; wing cell m 3 open; vein R 2+3 shape smoothly sigmoid curved to wing margin. Abdomen acutely tapered; tergite 2 with a concentrated patch of shortened setae posteromedially or all setae uniform and regular in length; male frequently with extensive silver velutinous pubescence. Male genitalia (Fig. 32A–E) with gonocoxite with outer gonocoxal process present; velutum patch absent, posteromedial margins proximal so that medial atrium is absent; inner gonocoxal process present and articulated; hypandrium triangular; ventral lobe elongate and rounded apically; aedeagus with dorsal apodeme of parameral sheath subtriangular, distiphallus straight, relatively short, narrow distally (rarely wide); lateral ejaculatory apodeme relatively large and elongate. Female genitalia (Fig. 32F) with furca relatively large and sclerotised; three spermathecae, ducts joining to spermathecal sac duct near furca; spermathecal sac round, relatively small; female acanthophorite macrosetae with two sets present (A1 &amp; A2); A1 enlarged, female sternite 8 posterior margin emarginate posteromedially.</p> <p>Included species. Pachyrrhiza argentata Oldroyd, 1968: 383, P. argentatoides sp. n.; P. elegantissima sp. n.; P. parargentata sp. n.; P. pictipennis Philippi, 1865; P. subpictipennis sp. n.</p> <p>Comments. Compared to other South American therevid genera Pachyrrhiza has a surprisingly limited distribution throughout central Chile and adjacent Argentinian provinces (Fig. 35). South American agapophytine therevids are almost completely restricted to the southern and western Patagonian Region, which may reflect their close phylogenetic connection to Australasian genera where the greatest diversity and species-richness is found in semiarid, subtropical to temperate regions, especially in Mediterranean-type climates. Pachyrrhiza is similarly restricted to semi-arid to Mediterranean habitats in the western Patagonian region. South American genera in subfamilies Therevinae and Phycusinae have much wider distributions throughout South America northwards into Central and North America. Pachyrrhiza argentata and P. pictipennis are the most commonly encountered species of the genus, although their respective distributions are relatively limited and apparently overlap very little. The remaining four species are found in similar habitats and are more locally distributed in the same region of central Chile and western Argentina.</p> <p>Pachyrrhiza is a distinctive genus recognisable by the enlarged and bulbous antennal scape, narrow male frons, two pairs of scutellar macrosetae, parafacial with small patch of dark setae (absent in female of some species), single row of postocular macrosetae in the male and at least one large anteroventral macroseta on the hind femur. It is closely related to Sigalopella Irwin &amp; Winterton, and these genera along with Entesia and Melanothereva form a monophyletic group (i.e., Entesia genus group, sensu Winterton et al. 2016) sister to the Taenogera genus group found in Australia, New Zealand and New Caledonia (Winterton et al. 1999b; Winterton et al. 2016; Irwin et al. 2020). The key to genera of South American Agapophytinae by Irwin &amp; Winterton (2020) can be used to identify individuals of Pachyrrhiza.</p> </div>	http://treatment.plazi.org/id/6B6D2072FFF7FF1B48D1F8FA91C02F8B	Public Domain	No known copyright restrictions apply.

Body length: 5.0– 6.8 mm. Head with frontal pubescence light brown dorsally, silver around antennal base, dark brown band above antenna in female; parafacial with small dark patch of setae adjacent to gena; genal setae pale; male frontal vestiture consisting of patch of short setae above antenna, shorter than setae on scape; female frontal vestiture consisting of scattered dark, short to moderate length setae; occiput grey with brown pubescence; antennal scape length slightly longer than maximum width, brown, overlain with grey pubescence, numerous erect, large black macrosetae; flagellum brown with grey pubescence. Thorax with scutum pubescent grey with broken, dark brown stripes, some setal bases dark brown, two dark medial stripes anteriorly joining posteriorly, lateral stripes irregular, vestiture as numerous erect black setae, longer and denser in male; prosternum with setae present or absent medially; pleuron dark, overlain with grey pubescence; katatergite setae all white; posterior surface of mid coxa without setae, rarely with a few white setae present; femora dark brown (usually males) to dark yellow, suffused with brown-black dorsally (female), short dark setae admixed with elongate pale setae ventrally; hind femur with 1 or 2 subapical anteroventral macrosetae; tibiae yellow, dark grey-brown apically; tarsi dark yellow with apices brown; wing mottled dark infuscate, fenestrate in some cells; costal cell brown infuscate basally, yellow infuscate distally; scutal chaetotaxy (macrosetae pairs): notopleural 3, supra alar 1, post alar 1, dorsocentral 3–5, scutellar 2. Abdomen of male abdomen base colour dark brown dorsally, yellow laterally, silver velutum on tergites 2–7, male vestiture mostly elongate pale setae, denser laterally; terminalia dark yellow; female abdominal markings mostly dark brown, posterior margin pale, broader laterally, intersegmental membrane distinctly pale coloured, well defined. Male and female genitalia as per genus description except male with epandrium with dark medial stripe; aedeagus with distiphallus narrow apically.</p> <p>Comments. Pachyrrhiza argentata is easily distinguished from other Pachyrrhiza species by the mottled wing pattern, 1–2 subapical anteroventral macrosetae on the hind femur and male abdomen with silver velutum. It appears closely related to P. parargentata sp. n. and P. argentatoides sp. n. and while their respective distributions overlap, P. argentata is more widely distributed along the Argentinian eastern slopes of the southern Andes mountain range (Fig. 35).</p> <p>Type material.

Body length: 5.5–8.0 mm. Head with frons silver-grey pubescent with dark brown markings, lighter brown dorsally in female, silver pubescent around antennal base, small patch of setae on frons just above antenna, similar in length to setae on scape, female with short to moderate length setae distributed over frons; occiput grey to brown pubescent; parafacial with small patch of dark setae adjacent to gena; genal setae pale; antennal scape length approximately twice maximum width, brown (male) or dark yellow, brown suffusion dorsally (female), overlain with grey pubescence admixed with numerous large, erect macrosetae; flagellum brown to dark yellow with brown pubescence. Thorax with scutum and scutellum grey pubescent with, narrow dark medial stripe, lateral stripes broken to sub-tessellate, numerous erect black setae (longer and denser anteriorly in male); prosternum with pale setae present; pleuron with silver-grey pubescence, katatergite setae all white, sometimes admixed with black setae; mid coxa without setae on posterior surface; femora dark brown, sometimes with apices yellow, short dark setae on all surfaces admixed with relatively elongate dark setae ventrally, hind femur with 3–6 (sometimes more) anteroventral macrosetae distributed along entire length; tibiae yellow, dark grey-brown apically and basally; tarsi dark yellow with apices brown; wing dark infuscate, fenestrate in some radial and medial cells, costal cell brown infuscate; scutal chaetotaxy: notopleural, 4; supra alar, 1; post alar, 1; dorsocentral, 4–5; scutellar, 2. Abdomen dark brown, slight yellowish suffusion medially, intersegmental membrane pale, narrow male without silver velutum on tergites, male vestiture as short dark setae dorsally, longer pale setae laterally, female setae uniformly distributed, short, dark, erect; terminalia brown. Male and female genitalia as per genus description except: epandrium brownish, darker medially, distiphallus narrow distally.</p> <p>Comments. Webb et al. (2013) noted that the syntypes deposited in the National Museum in Santiago, Chile could not be located yet could not be confirmed as destroyed. A ‘cotype’ determined by Kröber (1911: p. 489) as “ Dialineura pictipennis Phil. ” is deposited in the USNM but cannot be part of the syntype series as it was collected decades after the original description was published. Pachyrrhiza pictipennis is distinctive compared with other species in the genus based on the dark body colouration, extensive wing infuscation with small hyaline fenestrations distally and lack of silver velutum on the male abdomen; these are all evident in the original description and the figure plate provided by Philippi (1865: fig. 25); the identity of the species is not in question and a neotype is not necessary at this time. This species appears to be locally abundant in central Chile. Pachyrrhiza pictipennis appears closely related to P. subpictipennis sp. n. and P. elegantissima sp. n. based on wing pattern and presence of a series of anteroventral macrosetae along the hind femur.</p> <p>Type material. three syntype females, CHILE: Santiago Province: Region Metropolitana de Santiago, Cordillere (location unknown, presumed lost).</p> <p>Other material examined.

Parafacial with patch of black setae adjacent to gena; hind femur with 3–6 anteroventral macrosetae along segment length; prosternum with setae medially; wing mottled infuscate; abdomen brown, yellow laterally, male without silver velutum pubescence; mid coxa without setae on posterior surface; femora yellow to brown.</p> <p>Description. Body length: 5.8–8.2 mm. Head with frons light brown prubescent, silver around antennal base, setae dark, small patch similar length to scape setae above antenna in male, female vestiture distributed more widely over frons; occiput brown to grey pubescent; parafacial setae as small dark patch adjacent to gena; genal setae pale; antennal scape length twice maximum width, brown (male) or dark yellow with brown suffusion dorsally (female), overlain with grey pubescence admixed with numerous erect, large, black setae; flagellum brown with grey pubescence. Thorax with scutum pubescence mostly grey-tan with few brown markings (more in female), narrow dark medial stripe posteriorly, lateral stripes intermittent, setae on scutum and scutellum scattered and very short (female) or with numerous elongate fine setae, denser anteriorly (male); pleuron with dense silver-grey pubescence; katatergite setae variable, from uniform pale, admixed pale and dark, or uniform dark setae; prosternum with pale setal pile medially; mid coxa without setae on posterior surface; femora dark brown, or dark yellow with brown-black suffusion dorsally, short dark setae admixed with longer pale setae, denser ventrally; hind femur with 3–6 (sometimes more) anteroventral macrosetae along entire length; tibiae yellow, dark grey-brown apically; tarsi dark yellow with apices brown; wing extensively mottled infuscate, fenestrate in most cells, small fenestrations basally in medial cells; costal cell brown infuscate basally, yellow infuscate distally; scutal chaetotaxy: notopleural, 4; supra alar, 1; post alar, 1; dorsocentral, 4–5; scutellar, 2. Abdomen dark brown medially with sparse grey pubescence, dark yellow to bright yellow laterally, male abdomen without silver velutum on tergites, male with elongate pale setae, denser laterally, dark posteriorly, female setae uniformly short and dark, erect; terminalia dark yellow. Male and female genitalia as per genus description except: epandrium dark brown, distiphallus narrow distally.</p> <p>Comments. Pachyrrhiza subpictipennis sp. n. appears closely related to P. pictipennis, but is differentiated by the more mottled, lighter wing infuscation, and the abdomen with yellow laterally on most tergites. These characters in addition to the number of anteroventral macrosetae on the hind femur are distinctive for this species to separate it from others in the genus. Pachyrrhiza subpictipennis sp. n. is only known from a relatively small coastal region in northern Chile.</p> <p>Type material.
