Diagnosis. This species is similar to L. zhengi sp. nov. and L. plinthochroa (West, 1931) externally. It can be distinguished from L. plinthochroa in the male genitalia by the trifurcate, distal process of the gnathos, outer dorsal process of the sacculus about 2/3 the length of the inner one, and outer margin of the median plate of the valva obtusely rounded; in the female genitalia by the entirely membranous ductus bursae about 1/2 the length of the corpus bursae; in L. plinthochroa, the distal process of the gnathos is hooked, outer dorsal process is about 1/3 the length of the inner one, and outer margin of the median plate is strongly produced to a lobe (Wang et al. 2017, Fig. 20); and in the female the basally sclerotized ductus bursae is about 1.2 times as long as the corpus bursae (Wang et al. 2017, Fig. 30). The differences between L. strumiformis and L. zhengi are stated in the diagnosis of the latter species.
Description. Adult (Fig. 3) wingspan 20.0–25.0 mm. Head yellowish white. Male labial palpus black mixed with yellow and reddish-fuscous scales; first segment about 1/6 length of second; second segment curved dorsad, appressed to vertex, hollowed out on inner side to receive long brush-like maxillary palpus; third segment tapering, yellow, about 1/5 length of second; female labial palpus thinner than male, third segment about 2/3 length of second. Male maxillary palpus long, brush-like, white; female maxillary palpus compressed and short, yellowish white. Antenna yellowish-fuscous, male serrulate on ventral surface; female with black annulations on dorsal surface; scape extension apically reaching end of metathorax, black suffused with yellow scales, basal half with long black mixed with yellowish white hair-like scales ventrally, yellow hair-like scales apically. Thorax and tegula yellowish white mixed with black and fuscous. Forewing with basal area black, suffused with yellowish white scales; median area pale pink mixed with yellow and black; distal area fuscous, along veins with white strips edged by black along both sides; costal margin yellow, with black scales scattered to postmedian line; antemedian line black, extending from basal 2/5 of costal margin slightly obliquely inward to lower margin of cell, then inward to basal 1/4 of dorsum, edged with pale pink fascia along inner margin; postmedian line black, extending from distal 1/3 of costal margin slightly arched inward to base of M 3, then slightly obliquely inward to distal 1/3 of dorsum, edged with pale pink fascia along both inner and outer margins; subterminal line fuscous, extending from distal 1/4 of costal margin slightly arched outward to distal 1/5 of dorsum, edged with wide yellow fascia along inner margin and narrow pale pink fascia along outer margin; cell with a longitudinal yellow fascia from middle to anterior 1/3 of antemedian line, with a black tuft from base of lower margin to antemedian line; yellowish fuscous patch from base of CuA 2 to middle of dorsum; discal spot absent; discocellular spot represented by a black tuft, brownish yellow on outer side; terminal line yellowish white. Hindwing concolorous with forewing; blackish-gray patch from below base of cell to dorsum, with a tuft of black mixed with white scales medially; wide yellow fascia extending from base of Rs to middle of dorsum, suffused with yellowish fuscous tufts; black hair-like scales between M 1 and M 2 and between 1A and 2A longitudinally. Cilia of both wings pale, brownish-yellow. Legs pale yellow, fore- and mid-femora and tibiae suffused with fuscous scales, fore tarsus with longitudinal fuscous strips. Abdomen white on ventral surface; yellow on dorsal surface, suffused with fuscous and black scales, each segment yellowish-white terminally.
Male genitalia (Fig. 34). Uncus broad, sub-quadrate, covered with short setae dorsally. Gnathos lateral arms narrowly banded, joined apically; distal process trifurcate. Valva narrow basally, widened distally, obtuse terminally, covered with sparse hairs, tuberculate ventroapically; weakly sclerotized median plate umbraculiformis, oblique outward, widened posteriorly, widely fused with sacculus posteriorly; costa reaching apex of valva, distal 1/3 slightly expanded. Sacculus reaching apex of ventral margin of valva; dorsal process at middle, bilobed: inner lobe slender, arched outward, outer lobe slightly curved inward distally, about 2/3 length of inner lobe, thicker. Juxta subrounded; lateral lobes broad, slightly narrowed to pointed apex. Saccus U-shaped. Phallus slightly curved medially, slightly longer than ventral margin of valva, with denticles on distal 1/6; with one spine-shaped cornutus.
Female genitalia (Fig. 46). Papillae anales sub-triangular, obtuse posteriorly, with long setae. Ovipositor with sclerotized sub-rectangular plate anteriorly. Eighth segment rectangular, sternite narrowed medially, about 1/2 width of lateral margin, with sparse short setae posteriorly. Apophyses anteriores about equal length of apophyses posteriores. Lamella antevaginalis sub-rhomboid, shallowly concave medially. Antrum inverted trapezoidal. Ductus bursae membranous. Corpus bursae elongated, twice as long as ductus bursae; signa ovate, with dense denticles.
Distribution. China (Anhui, Fujian, Guangdong, Guangxi, Hainan, Henan, Jiangxi, Shaanxi, Zhejiang).
Etymology. The specific name is derived from the Latin strumiformis, referring to the valva tuberculate ventroapically.
