Type materials.
Holotype: China • 1♂; Hunan Province, Shaoyang City, Suining County, Jiuxi Bamboo Tower Villa; 26°24.39'N, 110°05.68'E; alt. 630 m; 25-v-2021; light trap; L. Peng leg.; NJAU Tricho-20210525-0001. Paratypes: China • 1♂; same data as holotype; NJAU Tricho-20210525-0002 • 1♂; Hunan Province; Shaoyang City, Suining County, Guanyinxing; 26°24.77'N, 110°05.39'E; alt. 550 m; 28-v-2021; light trap; L. Peng leg.; NJAU Tricho-20210528-0001.
Diagnosis.
This species is similar to Lype lubaretsi Arefina, 2005 from Russia. However, the new species can be easily distinguished by the following characteristics: (1) longitudinally, sternum IX of L. sagittalis sp. nov. is subtriangular in lateral view, rather than subrectangular in L. lubaretsi ; (2) each of the coxopodites of the new species is subcircular in lateral view, but elliptical in L. lubaretsi ; (3) the fused coxopodites in ventral view have a narrow mesal notch in the new species, rather than with a wide mesal notch in L. lubaretsi ; (4) the aedeagus is sagittal, with its apex truncate in dorsal view and pipe-shaped in lateral view in L. sagittalis sp. nov., but nearly triangular with apex broad in ventral view, triangular with a sharp apex in lateral view in L. lubaretsi .
Description.
Male. Length of each forewing 4.2-4.4 mm (n = 3), holotype 4.4 mm. Specimens in alcohol with compound eyes black; antennae, legs, and thorax brown; wings light brown without any distinctive markings; abdomen dark brown dorsally, pale yellow ventrally. Genitalia: Sternum IX subrectangular, anterior margin shallowly concave, posterior margin more deeply concave in ventral view (Fig. 4A View Figure 4 ); subtriangular in lateral view (Fig. 4C View Figure 4 ). Tergite IX covered with fine microchaetae, subtriangular with distal end truncate in dorsal view (Fig. 4B View Figure 4 ); tongue-shaped in lateral view (Fig. 4C View Figure 4 ), broadly fused with segment X. Segment X subrectangular and almost surrounding phallic apparatus in lateral and ventral views (Fig. 4C, E View Figure 4 ); apex excised mesally in dorsal view (Fig. 4B View Figure 4 ). Superior appendages elongate-oval in dorsal view (Fig. 4B View Figure 4 ); lanceolate, tilted posterodorsad in lateral view (Fig. 4C View Figure 4 ). Coxopodites each subcircular in lateral view (Fig. 4C View Figure 4 ); bases fused with each other in ventral view and with narrow notch between them apically about half their length, each with setose posteromesal corner produced caudad (Fig. 4A View Figure 4 ). Harpagones twice as long as coxopodites, each more-or-less parallel-sided, each with lower margin slightly concave, upper margin sinuate in lateral view (Fig. 4C View Figure 4 ); the pair divergent basally, evenly curved laterad and mesad to become somewhat forcipiform, with bases and distal ends enlarged in ventral view (Fig. 4A View Figure 4 ). Phallotheca massive, constricted at middle in lateral view (Fig. 4C View Figure 4 ), with apical margin membranous. Aedeagus sclerotized, depressed, broad in dorsal and ventral views (Fig. 4D, E View Figure 4 ); pipe-shaped in lateral view (Fig. 4C View Figure 4 ). Subapical projection of aedeagus sclerotized, finger-like in lateral and dorsal views (Fig. 4C, D View Figure 4 ).
Etymology.
The Latin feminine adjective Lype sagittalis , meaning “arrow-shaped”, and refers to the shape of the aedeagus in dorsal and ventral views.
