Diagnosis

D. delongi can be distinguished from other species of Dwightla by the long narrowly pointed pygofer apex (similar in D. hercules but lobe is wider in that species) and the aedeagus with a pair of long apical falcate processes directed ventrally.

Etymology

This species is named after Dwight M. DeLong, author of 86 valid genera and 833 species of Deltocephalinae .

Type material

Holotype

♂, CAMEROON, Southwest , nr. Korup National Park, at bridge, 05°03’02.1” N – 08°56’41.0” E, 15-30 Mar. 2009, J.R. Cryan & G.J. Svenson, #8, coll. INHS.

Description

SIZE. ♂ 9.1 mm.

COLOR. General color reddish-brown.

BODY. Head slightly wider than pronotum. Crown broad; slightly longer medially than next to eye; about 4 x wider than width of eye; texture glabrous with longitudinal striae; depressed preapically; with 8 more or less well defined black maculae. Anterior margin of head with 3 distinct carinae. Ocelli on anterior margin of head; about 2 x their own diameter from adjacent eye. Face light brown; broad. Frontoclypeus shagreen; distinctly broadening dorsally. Clypellus widening apically; somewhat ovoid. Lorum large. Gena wide; with long fine erect seta laterad and distant from frontoclypeal suture. Antennal sockets large; near upper corners of eyes. Antennal ledges distinctly carinate. Antennae somewhat long, about as long as width of head. Pronotum carinate laterally; lateral margin about as long as width of eye; with ~10 more or less well defined black maculae in a fluctuate transverse line near anterior margin. Forewing with numerous short fine hairs on veins and wing surface; apices folded over, forming pointed apex; medial part of wing apex texture delicate; costal margin whitish, with small black spots near apex; with 1 or 2 crossveins between A1 and claval suture; with A1-A2 crossvein. Profemur row AM with AM1 and 2 or 3 more proximal macrosetae; intercalary row with fine setae apically, apparently with larger setae basally, basal setae continuous with row AV setae, generally in one row but with a few scattered setae; row AV setae long; dorsally with 2 apical and 4-5 more proximal macrosetae. Protibia rounded dorsally; macrosetae 1+7 (or so). Mesofemur row AV with ~10 short setae. Mesotibia dorsal setae ~5+7. Metafemur apical setae 2+2+1. Metatibia row PV macrosetae thick with 1-2 slightly smaller lighter setae between; dorsal surface with supernumerary short stout setae between rows AD and PD; pecten setae nearly equal in length. Metatarsomere I pecten setae with 6 platellae; PV seta platellate.

MALE. Pygofer incised dorsally nearly 2/3 its length; without macrosetae; produced caudoventrally; sharply pointed at apex. Subgenital plate triangular; with scattered macrosetae laterally. Connective broadly Y -shaped; stem very short. Style slender; preapical lobe evident in lateral view; apophysis digitate, turned slightly medially at apex, ventral side with rough texture and subapical small tooth. Aedeagus with pair of long falcate apical processes directed ventrally (holotype with one of these processes broken at base and directed anteriorly). Segment X long; sclerotized laterally and dorsally, and ventrally near apex.
