Diagnosis

Parasogata sexpartita sp. nov. can be recognized by yellowish orange to stramineous habitus ( Fig. 1A ) with uninterrupted white vitta from frons to tip of scutellum ( Fig. 1C ) and aedeagus with 6 subapical dorsal processes ( Fig. 2 A–C), segment 10 with two pairs of processes ( Fig. 2G ).

Etymology

The species name is derived from the Latin term ‘ sex ’, meaning ‘six’, plus ‘ partita ’, meaning ‘parted’, a reference to the number of subapical spines on the aedeagus. The specific epithet is intended to be feminine in gender to match apparent gender.

Type material

Holotype

INDIA • ♂; Nagaland, Jharnapani ; 25°75′58″ N, 93°84′39″ E; 23 Jun. 2019; Niranjan G.N. leg.; Hg light trap; NPC HEMT7 .

Paratype

INDIA • 1 ♂; same collection data as for holotype; NPC HEMT8 .

Description

MEASUREMENTS (mm). Male (holotype, NPC HEMT7) 4.6 long, 0.7 wide across eyes, 0.5 wide across hind margin of pronotum.

COLOURATION. Yellowish orange to stramineous. Vertex, pronotum and mesonotum with uninterrupted white vitta. Near-black bands follow lateral carinae from anterolateral compartments of vertex to frontoclypeal suture; median portion of frons white (continuation of dorsal vitta); clypeus pale medially, darker laterally. Genae orangish anteriorly, stramineous around (and including) antennae. Pronotum and mesonotum dark yellow. Forewings and hindwings yellow-hyaline with prominent black veins. Legs yellowish white. Abdomen yellowish orange ( Fig. 1 A–D).

MORPHOLOGY. Head including eyes 0.9× as wide as pronotum. Head weakly produced, vertex 0.3× as long as head width (including eyes) ( Fig. 1A, C ). Fastigium elliptical in lateral view ( Fig. 1B ). Frons longer than wide, lateral margins smoothly diverging to frontoclypeal suture, widest at apex; median carina forked at level of compound eyes. Clypeus as wide as frons basally, rostrum reaching mesocoxae. Antennae terete ( Fig. 1D ). Pronotum 3.2 × as wide as long, anterior margin truncate behind vertex, posterior margin broadly convex; lateral carinae diverging, not reaching hind margin. Mesonotum 1.1× as wide as long; carina not conspicuous, obsolete before hind margin, lateral carinae weakly diverging ( Fig. 1C ). Forewings with R fork proximate to CuA fork; cell formed between fork of R and nodal line longer than that of cubitus; clavus long, reaching wing margin past basal ¾ of wing (approximately at nodal line); fork of Pcu+1A in basal ¼ of wing; branching pattern: RA unbranched, RP 2-branched (RP

1+2

, RP

3+4

), MP unbranched, CuA 2-branched.

MALE GENITALIA ( Fig. 2 ). Pygofer in lateral view approximately quadrangular ( Fig. 2F ), anterior margin nearly truncate, caudal margin convexly rounded (in lateral view), 1.2× as long as wide; margins of opening rounded (not carinate). Diaphragm well developed, dorsal margin concave, armature weak ( Fig. 2D ). Parameres diverging, rather sinuate, 6.1× as long as wide; widest subapically, apically acute ( Fig. 2H ). Aedeagus 8× as long as wide; shallow tubular, dorso-basally concave, subapically ornamented with six radiating spines dorsally; apically recurved with dorsal gonopore ( Fig. 2 A–C). Segment 10, including segment 11, 0.7× as long as wide (in lateral view) with two pairs of latero-apical pointed processes (dorsal tooth-like, ventral more elongate and directed ventrad); segment 11 long ( Fig. 2G ).

Molecular data

The DNA barcode fragment (mtCOI ~ 650bp) sequence was submitted to NCBI GenBank with accession number MN787519 .

Remarks

This species is similar to P. binaria and can be distinguished by an aedeagus with six radiating spines ( Fig. 2 B–C) (vs ten in binaria ) subapically and dorsal gonopore.

A peculiar aspect of the forewing venation is that the MP vein bends sharply at the nodal line, and it is not entirely clear whether it is angled toward the leading or trailing portion of the wing, a matter that could change the interpretation of the vein branches. Both previously described species of Parasogata appear to have the RP 3-branched (RP 1+2, RP 3, RP 4).

There are no host associations reported for any species of Parasogata .
