Diagnosis

Triraphis ocellatus sp. nov. is a species with the shortest ocellus-eye distance, which is about ¼ of lateral ocellus width ( Fig. 2B ). This species keyed to T. simphlex Valerio, 2015 using Valerio & Shaw’s (2015) key based on the ocellus-eye distance; however, T. ocellatus sp. nov. can be distinguished from the latter species by having more than 50 flagellomeres (in one of the paratypes, the remaining type specimens had the antennae broken) and by the brown coloration in the last three metasomal tergites.

Etymology

The name of this species refers to its ocelli, which are distinctly bigger than the ocelli of the remaining species.

Length of mesosoma 2.4 times its maximum width (dorsal view), 1.3 times its maximum height (lateral view); pronotal groove smooth and scrobiculate, wide apically; propleuron colliculate; notauli wide, deep and scrobiculate, not meeting, finishing just before the end of mesoscutum; medial pit present; median and lateral mesoscutal lobes strongly colliculate, lateral lobes turning coriaceous near notauli posteriorly; mesopleuron smooth-colliculate, dorso-laterally costate; precoxal sulcus wide, deep and scrobiculate, running along two thirds of mesopleuron, almost vertically strigate below precoxal sulcus; metapleuron colliculate-coriaceous turning areolate posteriorly; with a distinct, posterior tubercle; propodeum rugose-areolate, basally colliculate, median carina ¼ of propodeum length, areola and basal areas almost indistinct.

LEGS. Hind coxa 1.5 times longer than wide. Length of hind femur 5.0 times its maximum width. Hind basitarsus 0.5 times longer than hind tibia; length of hind basitarsus 0.85 times combined length of second to fifth tarsal segments. Second, third, fourth and fifth tarsal segments 0.4, 0.3, 0.2 and 0.25 times as long as basitarsus. Tarsal claws with a basal, pointed lobe, followed by sharp spines.

WINGS. Fore wing length about 2.6 times its maximum width; pterostigma 4.3 times longer than wide; vein lCUb 0.88 times vein RS+Ma; vein 3RSa 0.6 times vein 3RSb, 4.0 times vein r; angle at union 2RS and 2M wide. Hind wing length 3.6 times its maximum width; vein M+CU almost as long as vein 1M and 2.3 times vein r-m; vein 1A 1.2 times vein cu-a.

METASOMA. 1.6 times longer than head and mesosoma combined, with seven visible tergites. First tergite, 1.4 times longer than its maximum width; maximum width about 2.0 times its basal width; longitudinally costate with coriaceous sculpture between carinae, with a longitudinal median carina running along its entire length. Length of second tergite 1.1 times its maximum width, 2.0 times length of third tergite, second tergite longitudinally costate with coriaceous sculpture between carinae; third tergite longitudinally costulate on basal two thirds, finely coriaceous on apical third.
