With paired scoli dorsally, directed dorsally or almost so, bearing tuberculate chalazae; forewing pad costal margin straight; forewing pad chalazae sparse, chalazal setae long, without costal chalazae; dorsal scoli 2-4 5 basal width; condition of lateral rows undetermined. Metathorax. With paired scoli dorsally, directed dorsoanteriorly, length 2-4 5 basal width, bearing tuberculate chalazae. Legs. Chalazae of tibia on anterior and posterior lateral margins, absent or very few on dorsal surface. Abdomen. Terga III-VIII ventrolateral marginal condition undetermined; terga III-VIII with paired dorsal scoli, unequal in size, but not clinally; terga III-VIII tallest dorsal scoli 2-4 5 basal width, apically acute; tergum IV dorsal scoli directed dorsally or almost so; terga III-VIII with lateral rows.

Material examined.

Tynelia godoyae Creão-Duarte & Sakakibara, images of 3 nymphs, 1 adult, COLOMBIA. Antioquia. Remedios, vereda La Cruz, finca La Brillantina, N 6.8840833 W 74.5713056, 500m, rastrojo manual, abr-2014, C. Flórez (Camilo Flórez collection).

Discussion.

This voucher material represents a new country record for both the genus and species. Tynelia most closely resembles Neotynelia , but differs in having long chalazal setae and in lacking the extended ventral apex of abdominal segment IX.
