Diagnosis. Males of L. franckei sp. n. resemble those of L. lancetillae Galiano, 1980 in the general morphology and disposition of sexual characters, but differ from them in having three additional embolic apophyses, placed distally in the palp, together with a more slender and less wide embolic apophysis base ( Figures 4-9 ).

Metatarsus I-II v 2-2-2, p 1 pr, r 1 pr; III v 2-2-1, p 1 pr, r 1 pr; IV v 1 di, p 1 me, r 1 me. The tarsal claws have nine teeth, being surrounded by a dense claw tuft ( Figure 3 ). Abdomen with two diffused dorsal, lateral and longitudinal brown stripes ( Figures 1-2 ), 2.53 long, 0.99 wide. Palp ( Figures 4-9 ): with a lateral, short and thick embolus, armed by five embolar distal apophyses (arrow in Figure 7 ), all together in a common embolar apophysis base (eAb); median apophyses (MA) with a ventral projection (vpMA). The palpal tibia has a little dorsal and distal projection, and the cymbium is short, and brownish, with a relatively large paracymbium.

Distribution and Comments. Mexico (Chiapas) ( Figure 19 ). The holotype male was collected by hand at night, in a low forest. The species has been found in sympatry with L. deinognathus and L. jemineus . Known altitudinal distribution: 150 m.
