Bustamante, et al. 414 (holotype FCME!, isotype MEXU!). Fig. 1. Spigelia ayotzinapensis is similar to Spigelia mocinoi because of its sessile, ovate-lanceolate leaves without stipules.

039E87C0D55FFF851B990A118D7C8E73.taxon	etymology	Etymology: — Spigelia ayotzinapensis is named in honor of the 43 missing students, nine dead and 27 wounded, from the Escuela Normal Rural Raul Isidro Burgos in Ayotzinapa, Guerrero, Mexico on September 26 – 27, 2014. We are all Ayotzinapa. ¡ Vivos se los llevaron, vivos los queremos! Habitat: — The new species can be found in Quercus forest, at 2078 m elevation, with annual precipitation of 800 – 1200 mm and average annual temperature of 20 – 29 ° C (Rzedowski 2006, Challenger & Soberón 2008).	en	Islas-Hernández, C.

039E87C0D55FFF851B990A118D7C8E73.taxon	distribution	Distribution: — Species endemic to Mexico, restricted to the state of Guerrero. Phenology: — Flowering in July. The fruiting period is still unknown. Conservation: — Spigelia ayotzinapensis is known only from the type locality, recorded in the central-east of the state of Guerrero. The population was collected close to the municipality of Chilapa de Álvarez. Although the population seems abundant and the area surrounding the municipality is still conserved, the specimen was collected seven years ago and the locality is currently severely affected by livestock. We suggest assigning the category of critically endangered (CR) for this taxon (IUCN 2016), due to the very restricted area of distribution and the anthropogenic impact of the type locality.	en	Islas-Hernández, C.

Spigelia mocinoi is similar to Spigelia nicotianiiflora based on vegetative characters, but differs from the latter by its non-rhizomatous (vs. rhizomatous) plants, inflorescences with 3 - 5 flowers (vs. 8 - 9 flowers) and corolla lobes of 1.9 - 2 × 1 cm (vs. 0.9 - 1.6 × 0.4 - 0.5 cm). Perennial erect herbs of 25 – 30 cm tall. Stems cylindrical, pilose, monopodial. Leaves opposite, sessile; stipules absent; blades 2.9 – 3.3 × 1.7 – 2.1 cm, ovate-lanceolate, base rounded, apex acute, membranaceous, adaxially pilose, abaxially glabrescent.

039E87C0D55AFF801B9909FB8D0D82F6.taxon	etymology	Etymology: — Spigelia mocinoi is dedicated to José Mariano Mociño (1757 – 1820), a remarkable Mexican botanist born in Temascaltepec, the place where the new species was found. Habitat: — The new species can be found in tropical deciduous forest, at 1000 to 1300 m elevation, with annual precipitation of 800 – 1200 mm and average annual temperature of 20 – 29 ° C (Rzedowski 2006, Challenger & Soberón 2008).	en	Islas-Hernández, C.

039E87C0D55AFF801B9909FB8D0D82F6.taxon	distribution	Distribution: — Species endemic to Mexico, restricted to the Estado de Mexico. Phenology: — Flowering July to August. The fruiting period is still unknown. Conservation: — Spigelia mocinoi is known only from the type locality in Temascaltepec, Estado de Mexico. The specimen was collected over 80 years ago. However, 68 % of the territory of the municipality is preserved forest, so it is likely that the species is still occurring in the area. We propose to assign this taxon to the category of Data Deficient (DD) (IUCN 2016).	en	Islas-Hernández, C. Sofia, García, Rubí Bustamante, Alvarado-Cárdenas, Leonardo O.
