Diagnosis

This species can be recognized by the following combination of characters:

(1) hind wings without orange marking ( Fig. 7E View Figure )

(2) pro- and mesofemora and tibiae largely dark brown ( Fig. 7A–D View Figure )

(3) anal tube of male narrow and parallel-sided on basal third, then subrhomboid ( Fig. 8D View Figure )

(4) centroventral part of gonostyli with long laminate process hooked apically ( Fig. 8A, C View Figure )

(5) laterodorsal part of gonostyli strongly curved before apex and pointing laterodorsally ( Fig. 8A, C–D View Figure )

(6) rather large size: 10 mm

Etymology

This species is dedicated to Greg Daniels who collected the holotype, together with his wife Alice.

MEASUREMENTS AND RATIOS. LT: ♁ (n = 1): 10.0 mm; BV/LV = 4.7; BF/LF = 1.95; LP+LM/BT = 0.72; Ltg/BTg = 2.3; LW/BW = 1.86.

Male HEAD ( Fig. 7A–D View Figure ). Vertex concave with anterior and posterior margins parallel, curved; variegated brown and yellow-brown with darker marking at lateral angles. Frons brown variegated with yellowish, with 2 irregular black markings on disc. Clypeus elongate, brown variegated with yellowish, and darker apically. Genae pale yellowish, with brown markings around eyes and under antennae. Labium dark brown, reaching metacoxae. Antennae dark brown; scape short, ring-shaped; pedicel subcylindrical, slightly narrowing towards apex.

THORAX ( Fig. 7A–D View Figure ). Pronotum brown variegated with yellowish and with 2 small yellowish spots near lateral angles; obsolete median carina and 2 small impressed points on disc. Lateral fields of prothorax brown. Mesonotum brown variegated with yellowish; broad, irregular, black marking along median carina; disc slightly transversely wrinkled; median and peridiscal carinae weakly marked; median carina stopping before scutellum; slight impression before scutellum. Red ventrally. Tegulae brown, paler dorsally.

TEGMINA ( Fig. 7A, C View Figure ). Brown variegated with yellowish and black; large, irregular, apical black marking; pale yellow, oblique, sinuate line on vein A1 at half length of clavus; large triangular white marking on costal margin on nodal line, slightly variegated with brown; white marking at apicosutural angle, slightly variegated with brown. Maximum breadth at nodal line; costal margin slightly sinuate; apical margin obliquely rounded.

POSTERIOR WINGS ( Fig. 7E View Figure ). Black-brown, paler near base along costal and anal margins and along anal fold; elongate, transverse, rather small white marking at apicocostal angle, extending on 3 cells. Margin of anal area sinuate; sutural margin with 2 clefts, cubital one slightly marked.

LEGS ( Fig. 7A–D View Figure ). Pro- and mesocoxae yellowish brown. Pro- and mesofemora dark brown with 2 obsolete yellowish rings. Pro- and mesotibiae dark brown with 2 slightly marked yellowish rings. Pro- and mesotarsi brown with basal half of third tarsomere paler. Metacoxae red. Metafemora reddish yellow with apex brown. Metatibiae brown with 3 lateral spines yellowish basally and 8 apical black-brown spines. Metatarsi brown with a ventral row of 6 black spines on first tarsomere.

ABDOMEN. Bright red with genital segments black-brown.

MALE GENITALIA ( Fig. 8 View Figure ). Posterior margin of pygofer in lateral view strongly sinuate, strongly roundly projecting at dorsal ½, rather broad ventrally ( Fig. 8A, C View Figure ). Anal tube elongate, 2.05 times as long as broad, slightly curved ventrally in lateral view; lateral margins parallel on basal ½, rhomboid on apical ¾ with posterior margin rounded ( Fig. 8A–B View Figure ). Gonostyli fused basally and coalescent on 4/5 of length; diverging apically ( Fig. 8C View Figure ). Centroventral part elongate, laterally compressed and ending in a strong hook pointing dorsally ( Fig. 8A, C View Figure ). Laterodorsal part of gonostyli strongly sinuate in dorsal view with apical part strongly curved and directed dorsolaterally; lateral process in more dorsal position, slightly curved ventrally near apex and slightly directed anteriorly, longer than spoon-shaped process ( Fig. 8A, C–D View Figure ). Dorsal portion of phallobase high basally in lateral view, directed posteroventrally and with apical hook strongly curved dorsally ( Fig. 8E View Figure ). Ventral portion of phallobase along lateral margin of phallus, weakly sclerified, laterally flattened, elongate ( Fig. 8E–F View Figure ). Phallus dorsoventrally flattened, narrowing, bifid and slightly diverging apically in dorsal view ( Fig. 8E–F View Figure ).
