Heteroglenea Gahan, 1897: 490 ; Aurivillius, 1923: 510 [Catalogue]; Aurivillius, 1926: 89 [Key]; Gressitt, 1951: 566, 580.

Glenea (pars): Breuning, 1956: 2; Rondon & Breuning, 1971 [“1970”]: 527; Chou, 2004: 354; Ohbayashi & Niisato, 2007: 661.

Type species: Glenea nigromaculata Thomson, 1865 , by original designation.

Redefinition. Small-sized (under 11 mm). Head broad with tumid eyes, frons usually broader than long, sometimes as broad as long (male), eyes deeply concave, not divided. Antennae longer than body, scape slightly expanded, without ridge, antennomere 3 always the longest, antennomere 4 subequal to or longer than scape. Prothorax cylindrical, without lateral pronotal spine or tubercle. Elytra subparallel, each with one or two obtuse lateral carinae reaching neither the base nor the apex, truncated apically, without spines or teeth at apex. Procoxal cavity closed posteriorly, metepisternum more than twice as wide anteriorly as posteriorly, mid tibia grooved, hind femur reaching between mid third abdominal segment and apex of fourth abdominal segment. Both male and female with anterior claws bifid (Figs 11 & 33 & 46) and posterior claws simple (Figs 11 & 33 & 46).

Male terminalia: Apex of tergite VIII emarginate, or rounded, or with a protruding lobe in the middle, lateral lobes moderately slender, ringed part elbowed in widest portion, converging ( Figs. 37 a,c); median lobe plus median struts moderately curved, a little longer than tegmen, internal sac with 4–5 basal armature, 2 bands of supporting armature and 1–3 rods ( Figs 3 , 12 , 19 , 25 , 38 , 47 ). Female genitalia: spermathecal capsule with a stalk curved almost 180 degrees, apical part of stalk parallel with apical lobe (with basal part of stalk, sometimes) ( Figs 5 , 15 , 21 , 27 , 41 , 43 S, 50), except H. mediodiscoprolongata having the curve in middle of apical expanded lobe ( Fig. 34). Tignum ranged from about as long as to much longer than abdominal length in ventral view ( Figs 14 , 43 ).

Diagnosis. Differs from Glenea Newman by anterior claws in both sexes bifid and elytra without distinct lateral carinae; differs from Daphisia Pascoe by claws without sexual dimorphism.
