Sarimissus maculifrons
sp. nov.
(
Figs 1–11
)
Diagnosis.
This new species appears similar to
Eusarima contorta
Yang, 1994
, but differs by: 1) Frons with a pair of curved eyelike markings on the disc (
Fig. 4
), but the latter species without these eyelike markings (
Chan & Yang,1994
, fig. 45B); 2) Capitulum of gonostylus thick and short, with tip obtuse (
Fig. 9
), but long and slender, with tip acute in
E. contorta
(
Chan & Yang, 1994
, fig. 45E); 3) Aedeagus with a pair of short hook-like processes (
Fig. 10
), but the latter species with a pair of extremely long processes (
Chan & Yang, 1994
, fig. 45H).
Etymology.
This species name is a combination of Latin words “
macula
” and “
frons
”, referring to the light yellowish M-shaped markings on the frons.
Description.
Length: male (including forewings) (N=4): 5.1–5.2 mm.
Coloration.
Vertex brown, anterior, lateral and posterior margins all brown (
Figs 1, 3
). Compound eyes grayish brown, supported by grayish callus (
Figs 1, 3
). Frons brown, with an obvious light yellowish M-shape eyelike marking on the middle and some irregular yellow patches near base (
Fig. 4
); median carina brown from apex extending to near base, but not reaching to the frontoclypeal suture (
Fig. 4
); apical margin and lateral margins brown (
Fig. 4
). Antennae brown (
Fig. 4
). Postclypeus mainly brown, with light yellow near the base (
Fig. 4
). Gena brown, with one light yellow transverse fascia below compound eyes in lateral view (
Fig. 2
). Pronotum brown, anterior and posterior margins brown, median carina brown, only visible at middle (
Figs 1, 3
). Mesonotum brown, median and sublateral carinae all brown (
Figs 1, 3
). Forewings tawny to brown, longitudinal veins brown (
Figs 1, 5
). Hind wings brown (
Fig. 6
). Legs tawny, distributed with irregular brownish markings (
Figs 2, 4
).
Head and thorax.
Vertex 1.5 times wider in midline than long in midline, lateral margins nearly parallel, slightly concave at middle (
Figs 1, 3
). Frons 1.0 times wider at widest part than long in midline, 1.6 times wider at widest part than apical margin (
Fig. 4
); lateral margins nearly parallel from the apex to the middle of compound eyes, then expand to below antennae and finally narrow to the base (
Fig. 4
); sublateral carinae weakly present or invisible (
Fig. 4
). Pronotum 3.0 times wider at posterior margin than long in midline, 1.0 times longer in midline than vertex (
Figs 1, 3
); median carina weakly present or absent, with a small incision on each side of midline (
Figs 1, 3
). Mesonotum with anterior margin 1.8 times wider than long in midline, 1.7 times longer in midline than pronotum, median carina visible from anterior margin elevated to the basal 1/4, sublateral carinae elevated from anterior margin to the posterior margin (
Figs 1, 3
). Forewings 2.2 times longer at longest part than widest part, CuA forking slightly after MP (
Figs 2, 5
), MP1+2 vein bifurcate at apical 1/6 (
Figs 2, 5
), MP3+4 vein forked at apical 1/6 (
Fig. 2
) or unforked (
Fig. 5
), CuA1 and CuA2 unforked (
Fig. 5
). Metatibiotarsal formula: (2)–7/(8-10)/2.
Male genitalia.
Anal tube in lateral view curved downward near apex (
Fig. 7
), in dorsal view long cylindrical, widest at basal 1/3, 3.0 times longer in midline than widest part, apical margin rounded, lateral margins nearly parallel at apical half and convex at basal half (
Fig. 8
); anal opening located at basal 1/3 of anal tube (
Fig. 8
). Pygofer in lateral view long and slender, 2.6 times higher in midline than broad in midline, dorsal margin strongly sloping posterior, posterior margin convex at middle (
Fig. 7
); tectiductus large and broad (
Fig. 7
). Gonostylus in lateral view gradually broadened to apex, widest at apical 1/4, dorsal margin elevated at middle, then parallel with ventral margin; ventral margin deeply expand downward at basal 1/9 then straight with caudo-ventral angle subrectangular (
Fig. 9
). Capitulum of gonostylus directed cephalad, with an arc-shaped antero-lateral process on the base and a finger-shaped postero-lateral process at base (
Fig. 9
). Periandrium dorsal lobes slightly shorter than lateral lobes, the apical part laminar (
Fig. 10
). Periandrium lateral lobes in lateral view rounded in the apex (
Fig. 10
), in ventral view the median part deeply biforked (
Fig. 11
). Periandrium ventral lobe in lateral view rounded at apex (
Fig. 10
), in ventral view with apical margin rounded, lateral margins nearly parallel (
Fig. 11
). Aedeagus with a pair of short broad hook-like processes derived from apical 1/6, this pair of processes in lateral view curved downward then extending to the apical 1/3 of periandrium, tip pointed slightly surpassing the ventral margin (
Fig. 10
), in ventral view this pair of processes curved outward (
Fig. 11
)
