Madachauliodes ranomafana Penny

( Figs. 2 , 20–26 , 38 )

Madachauliodes ranomafana Penny, 1999: 194 . Type locality: Madagascar ( Ranomafana ).

Diagnosis. In appearance, this species is characterized by the brownish head with indistinct vertexal scars, the yellowish antennae, which are darkened on the distal half, and the MA vein connecting to Rs on the hindwing. This species is also characterized by the short and stout male ectoproct, the male tenth gonocoxite with median plate subtrapezoidal, and ventrally having a plate-like projection, the female eighth gonocoxite with two pairs of differently shaped sclerotized areas and a longitudinal incision, and the stout female ectoproct with obtuse apex.

Description. Male. Body length 23.7–31.2 mm; forewing length 28.1–31.8 mm, hindwing length 26.5–28.9 mm (n = 6).

Head pale brown; clypeus yellow, vertex medially with a pair of indistinct yellowish longitudinal scars; occiput dorsally with two pairs of yellowish brown scars. Compound eyes blackish brown; ocelli yellow, medially margined black. Antennae yellow on proximal half but dark brown on distal half. Mouthparts yellow; apex of mandibles, maxillary palpi, and labial palpi dark brown.

Prothorax uniformly pale brown; meso- and metathorax yellowish brown, but dark brown dorsally, metanotum yellowish medially. Legs yellow, densely setose; apex of tibia and entire tarsi brown; tarsal claw yellow with brownish tip. Wings ( Fig. 2 ) hyaline, pale smoky brown; pterostigmatic areas much darker. Forewing with numerous brownish spots, which are mainly along longitudinal veins, and with a darker marking across stem of 1A and anterior branch of 2A; markings on distal nygmata and branching point of CuA also darkened. Hindwing almost immaculate, distally with a few indistinct brownish spots along Rs. Veins dark brown. MA presents as an oblique veinlet distally connecting to Rs on hindwing.

Abdomen pale brown, pregenital segments dorsally with broad yellowish markings (visible only in specimens preserved in alcohol). Ninth tergum ( Fig. 20 ) subquadrate in dorsal view, with nearly truncate anterior and posterior margins. Ninth sternum ( Fig. 21 ) slightly shorter than ninth tergum, subtrapezoidal in ventral view, with posterior margin arcuately incised. Ectoproct ( Figs. 20–22 ) much shorter than ninth tergum, stout, straightly directed and gradually narrowed toward apex, posterolateral corner slightly prominent in dorsal view, inner portion bearing numerous small rhabdoid-shaped setae. Tenth gonocoxite ( Figs. 21–24 ) nearly as long as 3/4 of ninth tergum, posteriorly curved dorsad; lateral arm short and broad, anteriorly narrowed and posteriorly rounded in ventral view; median plate subtrapezoidal in ventral view, ventrally with a plate-like projection, which is directed ventrad and bears a small notch at tip.

Female. Body length 24.5–31.7 mm; forewing length 27.8–32.0 mm, hindwing length 24.7–28.9 mm (n = 6).

Eighth gonocoxite ( Figs. 25–26 ) broadly subquadrate in ventral view; laterally with two pairs of strongly sclerotized areas, anterior pair broad but posterior pair rather narrow; medially with a distinct longitudinal incision on anterior half; posterior margin slightly concaved medially. Ninth gonocoxite ( Fig. 25 ) broadly ovoid, with a stout gonostylus on posteroventral corner. Ectoproct ( Fig. 25 ) short and stout, with obtuse apex.
