Diagnosis.

Postmetopidium of pronotum, meso- and metanota, and abdominal terga IV-VII (usually III-VIII) each with pair of long scoli; segment IX posteriorly projected further ventrally than dorsally; body with chalazae with short subcylindrical setae; head with large or small scoli.

Nymphal description.

Overall body. Chalazal setae short; dorsal contour of abdomen in lateral view curvilinear; scoli splayed away from each other (except scoli parallel in Neotynelia pubescens (Fabricius)). Head. Simple conical scoli present or absent, if present then directed anterad; chalazal setae subcylindrical. Prothorax. Premetopidium scoli present, directed anteriorly; postmetopidium scoli present, directed dorsally; posterior extension of pronotum not surpassing anterior margin of metanotum. Mesothorax. With paired dorsal scoli, directed dorsally or almost so, bearing tuberculate chalazae; forewing pad costal margin straight, without chalazae (except present on base of costal margin in Neotynelia sp. 4); forewing pad surface chalazae sparse with short setae; dorsal scoli usually at least 5 5 basal width, rarely 2-4 5 basal width. Metathorax. Usually with paired scoli dorsally, directed anteriorly, up to 5 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 margins with or without single enlarged chalaza; terga IV-VII, and usually III and VIII, with dorsal scoli domen, very unequal in size, but not clinally, tallest dorsal scoli about 5 5 basal width, apically acute; tergum IV scoli basally directed dorsally or almost so, distally directed posteriorly; terga III-VIII lateral rows not manifested. Segment IX. Dorsal length subequal to combined length of segments V-VIII; apex with paired enlarged chalazae dorsally; ventral extension distinctly greater than dorsal extension.

Discussion.

Contrary to the majority of Neotynelia species examined in this study, Neotynelia sp. 1 has sparse to almost absent chalazae covering its entire body.
