Description

provided by Zookeys
Male: Total length 8.8 mm; forewing length 4.7 mm; head 1.0 mm in length; mesosoma 3.3 mm in length, petiole 1.2 mm in length; gaster 3.3 mm in length. Integument dark brown throughout (Fig. 3). Head with scrobal cavity carinate laterally; maxillary palpus 4-segmented, apical palpomere elongate, with numerous elongate black setae dorsally; clypeus bare except for two erect setae laterally near oral fossa (visible in left, oblique view); antenna apparently 11-segmented, apical flagellar article elongate and apparently with lines indicating possible fusion of two very minute apical articles (resulting in an otherwise 13-segmented antenna); parascrobal crests and vertex strongly tranversely striate, forming rasp-like structure dorsally. Mesosoma with pronotum and mesoscutum strongly, transversely strigate (Fig. 4), strigae increasingly bearing spicules posteriorly on mesoscutum; pronotum elongate, anterior margin rounded, posterolateral surface with striolate area (Fig. 4), striolate area ovoid (distinctly longer than wide; more rounded in L. rufus LaSalle and Stage), striations in striolate area finer and more evenly spaced anteriorly; mesoscutellum strongly transversely strigate, with numerous spicules; mesopleuron coarsely and irregularly punctate except in impressed region largely glabrous; propodeum laterally densely and contiguously punctate, with sparsely scattered setae. Procoxa with strong carina along dorsolateral margin; metacoxa sculptured as on lateral surface of propodeum; metafemur longitudinally striate ventrally except reticulate basally; metatibia without longitudinal rasp-like structure on inner surface; metabasitarsus twice as long as second tarsomere (tarsi pentamerous). Forewing with anterior margin of costal cell sclerotized (Fig. 5), with dense fringe of short fuscous setae; basal cell with 22 setae; sclerotized spot at junction of M+Cu and basal vein (Fig. 5); M+Cu composed of series of 14 setae and posteriorly by thinly sclerotized band leading to sclerotized spot (Fig. 5); hind wing with three hamuli. Metasoma with petiole approximately 7 times longer than wide (direct dorsal view not possible so this is estimated); petiole weakly transversely strigate dorsally; gaster imbricate.
