Name
Lumicella Lu & Qin gen. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type species
Lumicella rotundata Lu & Qin, sp. n., here designated.
Description
Body small. Head with eyes broader than maximum width of pronotum (Figs 1, 3). Vertex short, rounded anteriorly (Figs 1, 3), profile of transition to face rounded (Fig. 2), coronal suture long (Figs 1, 3). Face narrow and slightly convex in profile, lateral frontal suture present (Figs 2, 4). Forewing narrow, rounded apically, apical cells occupying less than one-third total length, all apical cell with separate bases, 2nd apical cell with margins subparallel but slightly broadened at apex, c and r cells nearly equal in width, narrower than m and cua cells; veins RP, MP’ arise from r cell and MP”+CuA’ from m cell (Fig. 9). Hindwing with bifurcation point of CuA basad of coalescence of CuA with MP” (Fig. 10). Male basal abdominal sternal apodemes developed, apically rounded and parallel sided (Fig. 8). Male pygofer elongate, strongly narrowing caudad, terminally with rigid microsetae on each side of lobe, ventral appendage present (Figs 5, 6, 11–13), dorsal bridge short, less sclerotized in middle dorsocaudad (Fig. 6). Subgenital plate much exceeding pygofer side, A-group setae distinct, C-group setae arranged in a single row and reaching apex of plate (Figs 5, 11, 18, 19). Paramere slim, apophysis bearing prominent dentifer and a few slender setae (Figs 5, 7, 11, 19, 20). Connective lamellate (Fig. 17). Aedeagus without dorsal apodeme, preatrium well developed, shaft tubular and curved twice, gonopore apical on ventral side (Figs 15, 16). Anal tube process curved and narrowed terminally (Figs 5, 7, 11, 14).
Etymology
The generic name is an arbitrary combination of letters, and is regarded as feminine.
Discussion
In Alebroides Matsumura group, the new genus is similar to Ghauriana Thapa, Membranacea Qin & Zhang, Dattasca Dworakowska, Luvila Dworakowska, Szara Dworakowska, Szuletaia Dworakowska, Luodianasca Qin & Zhang, Nikkotettix Matsumura and Znana Dworakowska in having veins RP, MP’ of forewing arise from r cell and MP”+CuA’ from m cell, all apical cells in fore wing having separate bases (in Nikkotettix and Znana, 3rd apical cell stalked or sessile) and CuA in the hindwing branched apically. However, this new genus differs from Membranacea, Luodianasca, Luvila and Szara in the presence of the ventral pygofer appendage (ventral pygofer appendage absent in these four genera), from Dattasca and Szuletaia in having bifurcation point of CuA basad of coalescence of CuA with MP” (apicad of coalescence of CuA with MP” in Dattasca and Szuletaia),from Znana in having coronal suture not reaching apex of vertex (surpassing apex of vertex and reaching the level of ocelli on face in Znana); from Ghauriana in the subgenital plate having A-group setae (A-group setae undifferentiated in Ghauriana), from Nikkotettix in the absence of ventral process at the base of aedeagal shaft (with ventral process at the base of aedeagal shaft in Nikkotettix). The new genus also differs from Membranacea in the presence of anal tube appendage (anal tube appendage absent in Membranacea) and from Luvila in having the C-group setae of subgenital plate arranged in a single row subbasally (C-group setae arranged in two rows subbasally in Luvila).
Distribution
China (Fujian).
