ETYMOLOGY. — Honours Leonardo Latella, the collector.

DIAGNOSIS. — Differs from congeners by the strongly reduced crests on the collum and metaterga, the completely undivided dorsal crests (the mediodorsal ones also undivided anteriorly), the complete depigmentation (even of ocellaria), the evidently elongated antennae and legs, the low, but evident, transverse pleural ridge behind the gonopod opening on male segment 7, etc.

DESCRIPTION

Length of adults of both sexes 18-45 mm, width 1.3-2.0 mm. Coloration usually uniformly dark brown due to heavy sclerotization, sometimes ozoporiferous tubercles reddish; more rarely, coloration uniform yellowish.

Adults of both sexes with 42-63p+6-1a+T; largest juveniles (♀) with 35p+4a+T or 36p+5a+T. Length of holotype about 30 mm, width 1.3 mm, with 50p+3a+T.

Antennae much more elongate than usual ( Figs 24A View FIG ; 26A View FIG ), with especially numerous and dense distodorsal sensilla on antennomeres 5 and 6 ( Fig. 25C View FIG ). Ocellaria, if any, unpigmented, ocelli, when present, 1-11, irregularly spaced, barely traceable. Gnathochilarium usual, mentum divided (n = 2) ( Fig. 26B View FIG ).

Carinotaxy of collum rather typical, though hardly traceable because of crests being nearly obliterated, especially anteromedially ( Fig. 24A, B View FIG ). Carinotaxy of subsequent metaterga deviating slightly from typical formula ( Figs 24 View FIG ; 25B View FIG ) in that none of the dorsal crests is divided transversely or longitudinally; all crests somewhat reduced ( Fig. 25B View FIG ), with only 2 or 3 very low lateral ones (formula 2(3)+I+3+I+2(3)). From segment 7 on, crest below “I” (i.e. below ozoporiferous tubercle) poorly divided at about midway; further ventrad, segments with 1 or 2 barely distinguishable crests followed by about a dozen fine striae ( Fig. 24A, D View FIG ). A low, but evident, transverse pleural ridge present behind gonopod opening on male segment 7. Epiproct slightly elongate apically, more narrowly rounded than usual; hypoproct more narrowly emarginate at caudal margin ( Fig. 25A View FIG ).

Legs elongate ( Fig. 25B View FIG ), about as long as midbody height; claws strongly elongate, with a small spine near base on legs of anterior 1/5-1/4 body ( Fig. 26F View FIG ), thereafter devoid of any basal spines ( Fig. 25D View FIG ). Male legs 1 with rudimentary tubercular coxites ( Fig. 26C View FIG ); male legs 2 and 3 typical ( Fig. 26D, E View FIG ).
