14893321609FA67DD62E628F2AB14E42.taxon	etymology	Etymology. The species epithet is a noun in apposition and refers to the volcano " La Malinche, Malintzi or Matlalcueye " (meaning " blue skirt " in Nahuatl language), a seismically active volcano (4,420 m) of the Transmexican Volcanic Belt, located in the states of Tlaxcala and Puebla. This last state is where the type locality is located.	en	Valdez-Mondragon, Alejandro, Cortez-Roldan, Mayra R., Juarez-Sanchez, Alma R., Solis-Catalan, Karen P.

14893321609FA67DD62E628F2AB14E42.taxon	diagnosis	Diagnosis. Loxosceles malintzi sp. n. resembles L. huasteca Gertsch & Ennik, 1983 and L. coyote Gertsch & Ennik, 1983 in having a long, slender male palpal tibia and by the embolus (Gertsch and Ennik 1983: figs 173 ‒ 176, 200 ‒ 203). However, L. malintzi has a more slender palpal tibia (Figs 22 - 24, 38, 55 - 62), 4.4 x longer than wide (in L. huasteca the tibiae is 2.7 x longer than wide (Gertsch and Ennik 1983: fig. 200), and L. coyote is 2.9 x longer than wide (Gertsch and Ennik 1983: fig. 173 )). The palpal tibia of L. malintzi is nearly straight (Figs 22 - 24, 55 - 62) (in L. huasteca and L. coyote it is more curved ventrally (Gertsch and Ennik 1983: figs 200, 173 respectively )). In dorsal view, the palpal tibia in L. malintzi is nearly straight (Fig. 23) (in L. huasteca and L. coyote it is more curved each side (Gertsch and Ennik 1983: figs 201, 174 respectively )). In retrolateral view, the embolus of L. malintzi is straight as in L. huasteca (Gertsch and Ennik 1983: fig. 200), but slightly shorter (Figs 24, 25); also, L. huasteca has a small spur near tip of embolus (Gertsch and Ennik 1983: fig. 202), which is absent in L. malintzi (Figs 25 - 27, 40, 41). The embolus in L. coyote (Gertsch & Ennik, 1983: figs 173, 176) is markedly longer and wider than in L. malintzi, which is smaller and more slender (Figs 22, 24 - 26, 38 - 41, 55 - 62). Females resemble L. colima Gertsch, 1958 (Gertsch and Ennik 1983: figs 291 ‒ 292) and L. devia Gertsch & Mulaik, 1940 (Gertsch and Ennik 1983: figs 42 ‒ 46) in having long and curved seminal receptacles; however, L. malintzi has seminal receptacles finger-shaped, shorter than those of L. colima and less curved than those of L. devia (Figs 30, 63 - 67); also, the base of the receptacles in the new species point obliquely and they are closer to each other (Figs 30, 63 - 67), whereas in L. colima and L. devia, the base of the receptacles are widely separated (Gertsch and Ennik 1983: figs 42 ‒ 46, 291 - 292).	en	Valdez-Mondragon, Alejandro, Cortez-Roldan, Mayra R., Juarez-Sanchez, Alma R., Solis-Catalan, Karen P.

F322D4207D274394102A896647F6262D.taxon	distribution	Updated distribution records for the 39 species of Loxosceles from Mexico. A total of 461 records of the 39 species of Loxosceles distributed in Mexico were reviewed. Twenty records were discarded for not having complete localities or having doubtful georeferences. Thus, a total of 441 records were used to make the distribution maps (Figs 73 - 76). The states with the most records are Guerrero with 55, Mo relos with 35, and Baja California Sur with 30 (Fig. 75). The state of Tabasco only has a single record (Appendix 1, Fig. 75). The most diverse states are Baja California Sur, Baja California, Sonora (with five species each), Guerrero, Tamaulipas (with four species each), and Oaxaca, Puebla, Hidalgo, Coahuila, San Luis Potosi, Nuevo Leon (with three species each) (Figs 73, 74). The least diverse states are Durango, Zacatecas, Michoacan, Queretaro, Chihuahua and Sinaloa (with two species each); Jalisco, Guanajuato, Quintana Roo, Colima, Chiapas, Yucatan, Campeche, Tabasco, Veracruz, Mexico City, Nayarit, Aguascalientes, Tlaxcala and state of Mexico (with a single species each) (Figs 73 - 76). Regarding the number of total records per species of Loxosceles, the species with the most records are L. boneti with 59 and L. colima with 57 (Fig. 75). The species with the least number of records are L. barbara, L. carmena, L. francisca, L. insula, L. luteola and L. rufescens with a single record each (Fig. 74). A new record of L. misteca was found for Tlaxcala (Figs 75). A third record of L. reclusa was found for Tamaulipas (Fig. 74). The record of L. rufescens from Ciudad Juarez, Chihuahua represents the second record for the country of this introduced species and the first well-documented and illustrated record from Mexico (Figs 68 - 72, 73, Appendix 1).	en	Valdez-Mondragon, Alejandro, Cortez-Roldan, Mayra R., Juarez-Sanchez, Alma R., Solis-Catalan, Karen P.
