Nothochrysa everetti van der Weele, 1909: 78 View in CoL . Type locality: Indonesia.

Diagnosis and notes

Nothochrysa evanescens was originally described from Malaysia by McLachlan (1869). Later, van der Weele (1909) described three subspecies: Nothochrysa evanescens javanica , N. evanescens everetti , and N. evanescens ludekingi . Among them, N. evanescens javanica and N. evanescens evanescens were transferred to Evanochrysa by Brooks & Barnard (1990), while N. evanescens everetti , and N. evanescens ludekingi were considered as independent species in Italochrysa . The photograph provided by van der Weele (1909: fig. 32) for Italochrysa everetti is almost identical to our examined specimen from Pakistan, particularly the third intracubital cell (icu3) distally with distinct brownish spot ( Fig. 4 View FIGURE 4 ). Therefore, we followed van der Weele (1909) and identified I. everetti based on a newly collected male specimen.

Redescription

Head ( Figs 9A–B View FIGURE 9 ). Vertex moderately raised, unmarked, brownish yellow, medially with an inverted V-shaped suture, rounded in frontal view. Postorbital sclerite brownish yellow, unmarked. Frons pale yellow, brownish yellow around base of antennal toruli; epistomal suture with an inverted V-shaped; covered with short yellow setae. Clypeus yellow, covered with short yellow setae. Labrum brownish yellow, with short yellow setae. Genae yellow. Maxillary and labial palpi brownish yellow, with short yellow setae. Antennae shorter than forewing length; scape and pedicel orange, covered with short yellow setae; flagellum dark brown, each flagellomere with five rings, with short black setae.

Thorax ( Fig. 9C View FIGURE 9 ). Pronotum wider than long (length 1.10 mm, width 2.00 mm), brownish yellow, with a broad median yellow stripe, covered with short black and yellow setae. Meso- and metanotum brownish yellow at lateral margins, except with a broad median yellow stripe, covered with dark brown setae. Pleurite brownish with yellow markings, covered with short pale setae ( Fig. 9E View FIGURE 9 ).
