Leprosoma olcesii FAIRMAIRE, 1886

( Figs 7, 15, 16, 29)

Material examined. Without geography designation (Jakovlev coll.), 2♀ ( ZISP) ; Morocco: (Puton coll.), 2♂♂, 2♀♀ ( MNHN) ; 1898 (Noualhier coll.), 2 ♀ ( MNHN) ; 1900 (Vaucher), 1♀ ( ZISP) ; Lalla ST, VI.1914 (de Bergevin coll.), 1 ♂, 1♀ ( ZISP) .

Diagnosis. Body rather large. Humeri long, rounded rectangular, rather curved forward. Intermediate pronotal carina absent. Posterior carina curved less strongly, but more sharply than in L. reticulatum . Elevations on connexival laterotergites strongly convex, tubercles in posterior corners of abdominal segments very large. Pygophore about as long as wide; its ventro-apical margin with very shallow trapezoid notch and slightly oblique, straight lateral parts ( Fig. 15). Ventral infolding of rim of pygophore and parandria very similar to those of L. tuberculatum . Parameres and aedeagus as in L. tuberculatum . Ventro-lateral lobes of conjunctiva forming wider obtuse angle in ventral view. Female genitalia very similar to those of L. reticulatum . Medial part of spermathecal duct as long as abdominal sternum VI or slightly extending beyond its anterior margin ( Fig. 29).

Measurements (mm) and ratios. Total length 6.00-6.80, width of pronotum 4.35-4.80, width of abdomen 3.85-4.50, ratio head length/head width 0.97-1.02, ratio scutellum width/scutellum length 0.54-0.57. Length of segments I-V of antennae: 12- 14:21-22:12-14:13-15:26-30.

Distribution. Recorded from Morocco ( Fig. 31).

L. olcesii was synonymized with L. reticulatum by Puton (1886) and restored by Horváth (1911). Other discriminating characters of L. olcesii , additional to the listed above, are given in the original description of L. olcesii and in Vidal’s (1949) key (head apex more broadly rounded, juga with deeper lateral incisures, posterior pronotal carina higher, posterior part of pronotum and all scutellum rougher), but these are not always diagnostic. Fairmaire (1886) considered L. olcesii to be merely a local variety of L. reticulatum with differences caused by the larger body size. The ratio of width of the pronotum to width of the abdomen is the character providing a dichotomy between these two species in keys. Specimens from Morocco examined by me show the following variability of this ratio: 1.0 (2 specimens), 1.11, 1.12 (2 specimens), 1.13, 1.16. Most likely, L. olcesii is not a separate species, judging by the co-existence of forms with short and long humeri in L. tuberculatum and continuity of distribution ranges of L. olcesii and L. reticulatum . However, the material examined by me is not sufficient for conclusion.
