description: Euphranta ridleyi Hancock & Goodger, sp. nov.
(Figs 49–52)
Description. Female. Body length, 6. 2 mm; wing length, 6. 5 mm.
Head (Fig. 49): higher than long, fulvous. Frons with three frontal setae and one orbital seta, all black and acuminate, the lower two frontal setae close together and widely separated from the upper frontal seta, which lies just anterior to the orbital seta; ocellar seta absent. Face, palp and antenna fulvous; arista plumose. Face concave, yellow without spots; gena, parafacial and occiput fulvous; postorbital and postocular setae thin and black.
Thorax (Fig. 50): mostly fulvous to red-brown; scutum red-brown, fulvous laterally, along suture and medial stripe, the latter with large yellow patch posteriorly; pleura largely red-brown, fulvous on posterior part of anepisternum Thorax with full complement of setae except presuturals lacking and prescutellar acrostichals abraded in holotype; dorsocentrals placed below line of supra-alars; 1 anepisternal seta. Scutellum yellow with a broad, red-brown basal area; two pairs of scutellar setae.
Legs: mostly fulvous; hindfemur with basal 1/2 to 2/3 fuscous; mid and hind tibia fuscous.
Wing (Fig. 52): length (holotype) 6.5 mm; vein R1 setose; R4+5 setose to level of DM-Cu crossvein; R-M crossvein below apex of stigma; cell bcu with broad apical extension; stigma, including apex, entirely dark brown, without hyaline area. Wing pattern hyaline with four dark brown transverse bands; subcostal band from base of stigma to vein A1+Cu2 at apex of cell bcu; discal band from apex of stigma across R-M crossvein to posterior margin in cell cu1; subapical band through crossvein DM-Cu reaches anterior margin, broad preapical band from cell r1 to m leaving a small hyaline spot at extreme apex of cell r1 and a broad hyaline apical patch in cell r4+5 that extends distinctly into cell r2+3 for 1/3 of its length and weakly into extreme apex of cell m.
Abdomen (Fig. 51): elongate-oval; segments 1 and 2 fulvous except segment 2 broadly fuscous medially, leaving lateral margins fulvous; segments 3 and 4 fused, fuscous with anterolateral and posteromedial margins fulvous, twice length of segment 5; segments 5 and 6 fuscous with large medial fulvous patches posteriorly; segment 6 about as long as segment 5; oviscape robust, a little longer than abdomen and tucked beneath it in the holotype; 2.6 mm in length, red-brown becoming fuscous apically; aculeus not exposed.
Material examined: Holotype Ƥ, SINGAPORE: labelled ‘ Singapore, H.N. Ridley, 1900-242’ (BMNH).
Etymology: Named after the collector, H.N. Ridley.
Remarks: The holotype is also labelled ‘det Staurella quadrifasciata Enderlein, F.A. Perkins’. The holotype was misidentified as E. corticicola by Hancock and Drew (2004) and its sex misstated. It resembles E. corticicola in head characters (including the approximated lower 2 pairs of frontal setae) and keys to that species in Hardy (1983); however, E. corticicola is a larger species that differs in having the apical hyaline wing spot only faintly extending beyond cell r4+5 into cell r2+3, the stigma hyaline at its apex, the transverse wing band over DM-Cu crossvein curved, the legs with all femora fulvous, the abdominal pattern different and the oviscape short, about as long as abdominal segments 5 and 6. The wing pattern is also very similar to that of E. separata Ito but the transverse wing band over R-M crossvein is straighter (curved at stigma in E. separata); the oviscape is also longer in E. ridleyi and the leg and abdominal patterns different (femora entirely fulvous and abdomen with a medial fulvous band on segments 2–6 in E. separata). The abdominal segment 6 and oviscape are similar to those of E. zeylanica (Senior-White) but other characters are very different.
