Figs. 6A, 16A–N, 17A–C, 18A–J, 34C, 35B, 36E,F, 37, 43
Diagnosis. In the male sex from L. longitubulata and L. gibberosa distinguished by the extremely short glandular pouches scarcely surpassing T7 anteriorly, from L. fenestrata, which also has short T7 pouches, distinguished by the presence of pairs of vesicular structures contained in the glandular pit.
Etymology. The species name refers to the vesicles (in Latin: vesicula, -ae) present in the glandular pit of T7.

Description. Size. Male. Length of pronotum 1.48–1.73 (mean 1.59) mm, length of tegmina 2,16–2.83 (mean 2.58) mm. (N = 8/11). Female. Length of pronotum 1.68–1.99 (mean 1.82) mm, length of tegmina 2.13–2.47 (mean 2.30) mm. (N = 7/9).
Wings. Apex of tegmina in the male usually straight, seldom very weakly concave, in the female usually weakly concave, seldom straight; hindwings in both sexes of variable shape, not broadening towards the apex (Fig. 16H,I).
Male abdomen. Tergites: Fig. 16A–G. T 6 as described under characters of the genus and the species group (Fig. 6A). T7. Pit size: minor, not larger than size 2. Anterior pit wall (aw) with strongly sclerotised area (sa) along the uper margin, well set off by a very dark colouration; towards below the area is limited by the widely bow-shaped edges ed (Fig. 18D) of a pair of relatively deep excavations of the anterior pit wall, mesally separated by the relatively short and narrow stabilising bracelet (s); occasionally, the excavation is deepening in two steps, with the formation of a second edge (Fig. 17B) further below. The pit contains structures looking like vesicles (vs) (Figs. 17B, 18B,H); more detailed analysis showed that they consist of a clew of tubular structures, presumably formed by the elongated endpieces of the pouches entering the pit via the windows (w, Fig. 17B) of the anterior wall. Posterior pit wall (pw) with bulges (bu) of very different shape and size (Fig. 18A–H). Glandular pouches (gp) very short, scarcely surpasing the anterior border of the tergite (Fig. 17B, 18B,E,G); tubules (tu) also very short, scarcely measuring more than halfway the distance to the lateral borders of the tergite. Genital hook with relatively normally shaped shaft, below the apical process not or only weakly bulged out (Fig. 16L–N).
Distribution. The species is in its distribution restricted to the northwestern corner of Morocco, fairly in congruence with the Region Ranger-Tétouan. So far no other species of Luridiblatta had been found within the distribution area of L. vesiculosa.
II. The trivittata- species group
1. Group-specific characters
Male T6. Mesal part of anterior border slightly more produced than in the preceding group, transversal ridge mesally interrupted or completely missing, near the lateral borders with a pair of small deepenings (Fig. 1B,C; for more details see description under characters of the genus).
Wings. Male tegmina longer than in the longitubulata -group, almost reaching the abdominal end, obliquely rounded (Fig. 19H) or obliquely cut (Fig. 22G). Hindwings of both sexes broadening towards apically, apex in the middle with a variously deep excavation or a steplike excision on one side (Figs. 19J,K, 21J).
Male genital hook as in the preceding group with relatively normally shaped shaft, diameter at middle length equals about a fifth of the total length, but shaft below the apical process strongly bulged out; other features as described under characters of the genus (Figs. 19L–N).
2. Characters common to longitubulata - and trivittata-group, differing in beybienkoi -group
